Autores: Baldi,Fernando; Laureano,Monyka Marianna Massolini; Gordo,Daniel Gustavo Mansan; Bignardi,Annaiza Braga; Borquis,Rusbel Raul Aspilcueta; Albuquerque,Lucia Galvão de; Tonhati,Humberto.
The objectives of this study were to estimate the genetic parameters for milk yield unadjusted and adjusted for days in milk and, subsequently, to assess the influence of adjusting for days in milk on sire rank. Complete lactations from 90 or 150 days of lactation to 270 or 350 days in milk were considered in these analyses. Milk yield was adjusted for days in milk by multiplicative correction factors, or by including lactation length as a covariable in the model. Milk yields adjusted by different procedures were considered as different traits. Heritability estimates varied from 0.17 to 0.28. Genetic correlation estimates between milk yields unadjusted and adjusted for days in milk were greater than 0.82. Adjusting for days in milk affected the parameter...

Autores: CAMARGO, A. C. de.
Este livro nasceu do desejo de me comunicar com os técnicos que atuam na extensão rural e com os produtores de leite. Queria mostrar minha forma de enxergar a atividade leiteira. Era o meu anseio partindo de um cenário de total desalento existente em muitas propriedades leiteiras, em especial, as de tamanho reduzido, mostrar os caminhos para a mudança da situação e, por fim, alcançar a realização plena, depois de um processo de transformação lento e longo. Tinha tentado me expressar em vários artigos, mas não estava satisfeito com o resultado. Apenas um aspecto isolado da atividade leiteira, tão complexa, era abordado. Ficava a sensação de ?quero mais?. Certa vez, lendo sobre os índices de audiência das telenovelas brasileiras e sobre como o povo daqui...

Autores: CAVALCANTE, F. A.
Há décadas, a pecuária leiteira é tratada como uma atividade de subsistência, mas hoje novas técnicas de gerenciamento e de manejo no rebanho precisam ser implantadas, para que o leite seja produzido com qualidade, caso contrário a pequena e a média produção serão prejudicadas no futuro. Vendo a importância do segmento da pecuária leiteira do País e o risco que a má qualidade do leite pode ocasionar à saúde pública, o governo estabeleceu padrões e regras para o setor, por meio da Portaria nº 56/1999 do Ministério da Agricultura, Pecuária e Abastecimento (Mapa), na qual delimita prazos, regras e números a serem cumpridos para o setor leiteiro de cada estado, visando à melhoria na qualidade do leite produzido pelos rebanhos leiteiros do País. Com o cenário...

Autores: 三浦, 伸也; 鈴木, 三義.
(社)北海道酪農検定検査協会の検定日記録および(社)日本ホルスタイン登録協会北海道支局の体型記録を用い，体細胞スコアと泌乳形質および体型形質との遺伝相関を推定した．各体型形質の記録数は審査開始時期の違いにより異なるが，多くの形質に共通な記録数を示すと，初産が181,291記録であり，2産が104,105記録，3産が30,973記録であった．遺伝相関の推定には，2形質分析モデルを用いた．母数効果としては，体細胞に対して，牛群・検定日，分娩月齢，分娩後日数の1次の回帰，分娩後日数に対するWilminkの指数項，体型形質に対しては，牛群・審査日，審査時月齢，泌乳ステージ，審査員の各効果を考慮し，さらに変量効果として両形質について，相加的遺伝効果と残差を含むモデルを用いた．体細胞スコアと乳生産形質との遺伝相関は−0.22〜0.15と低い値が推定され，初産において正の相関，2産以降では負の相関となる傾向が示された．体型形質と体細胞スコアとの遺伝相関は，産次により値が変動し，正負の符号の逆転が認められた．これは，加齢による体型変化に起因していると考えられる．体型形質の中で，乳房の深さ（−0.29〜−0.19）および前乳房の付着（−0.25〜−0.07）において，負の遺伝相関が推定された．これらの体型形質は生涯生産性，在群期間とも遺伝的な関連があり，これらの体型形質を改良することにより，体細胞スコアを低減することが可能であり，結果として生涯生産量の増加が期待できる．

全国的データを用いて，在群期間の遺伝率および初産泌乳形質，体型形質，および繁殖形質との遺伝相関の推定を行った．データは，社団法人家畜改良事業団に1975年から集積された1993年9月以前に誕生した雌牛の誕生，淘汰，泌乳，および社団法人日本ホルスタイン登録協会で集積された体型と血統記録である．在群期間は誕生から96ヵ月までの打ち切りデータとした．計算機の制約からすべてのデータを用いた遺伝的パラメータの推定は困難であった．そこで，同じ牛群コードをもつ記録が同一サブセットに無作為に分割されるように，遺伝率およびデータ数の限られる体型形質との遺伝相関の推定には10個，データの多い形質の遺伝相関推定には100個のサブセットを作成し，その中の10個のサブセットを用いて，制限最尤法（REML）により分散成分の推定を行った．在群期間の遺伝率は0.07と低い値が推定された．在群期間と初産泌乳形質における遺伝相関の推定値は，0.08から0.16と低いが正の関係が認められた．初産泌乳形質の向上させながら，在群期間に対する改善が可能であると考えられた．体型形質との遺伝的関連では，体の大きい個体を選抜することは負の関係にある在群期間の改良を妨げとなる恐れがあるが，正の比較的大きな遺伝相関がある肢蹄（0.37）や乳器（0.34）などを用いた間接選抜は有効であることが示唆された．在群期間と初産分娩月齢においては小さい負の値が認められ，初産から2産の分娩間隔における遺伝相関の推定値は小さい正の傾向を示したが，2産から3産の分娩間隔は0.15とやや高くなった．

Organic Dairy Farming in Norway Under the 100% Organically Produced Feed Requirement
Provedor de dados: 31
Autores: Flaten,   Ola; Lien,   Gudbrand D.
The EU regulation governing organic production will require 100% organic feed in organic dairy systems from August 2005 compared with 85% currently in Norway. This study aimed to assess adjustments in resource use and financial impacts on organic dairy herds using a discrete stochastic programming model. Farm management effects of the regulatory change varied between farm types. For the two organic dairy systems examined, both having a milk quota of 100 000 litres but with varying farmland availability, the introduction of the 100% organic feed regulation resulted in an economic loss of approximately 6-8% of the net income compared to the current regime. The economic loss was mainly due to the considerable higher price of organic compared to conventional...

Künftige Wettbewerbsfähigkeit der Milchproduktion im Berggebiet Österreichs und der Schweiz
Provedor de dados: 31
Autores: Kirner,   Leopold; Gazzarin,   Christian.
The mountain areas of Austria and Switzerland are important locations for dairy farming. Owing to natural conditions, the milk in these areas is produced at a considerably higher cost. Nevertheless, structural change in the mountain areas of both countries proceeded at a lower pace than in the plain areas. Milk production in the mountain area of Austria was appreciably expanded. This paper presents a number of attempts to explain these regional shifts, analysing the competitiveness of the farms, as well as the alternatives outside of milk production in the mountain and plain areas of Austria and Switzerland. In addition, we investigate whether milk production in these regions is also capable of holding its ground under future conditions. The on-average...

Like in other CEEC, transition in the beginning of the 1990s had significant consequences for the agricultural and food sectors in Slovakia. For example, Slovakian consumers reacted to the abolition of consumer subsidies by drastically reducing their consumption of milk and milk products. Concurrently, milk production declined and now stands at fifty percent of its 1989 level. Dairies were closed down while those remaining carried on producing under constantly increasing overcapacities. In the years prior to EU accession, activities in the milk sector were primarily aimed at the adoption of EU standards. Meanwhile, the Slovakian milk processing industry is predominantly in the possession of foreign investors. Present per capita consumption of milk and milk...

Moga District in Punjab, India, is a microcosm of the twin story of irrigation-induced growth and stress. The groundwater consumptive water use in agriculture exceeds the recharge by a substantial margin. Rice production contributes to a major part of this difference. The groundwater depletion is so critical that diversifying agriculture is the only way forward for sustainable agricultural growth. Reducing the rice area and intensifying milk production will be a win-win situation for both the farmers and the area reeling with a groundwater crisis.

ARMENIAN RURAL COOPERATIVES AND MARKETING: DAIRY SECTOR
Provedor de dados: 31
Autores: Hovhannisyan,   Vardges; Vasa,   Laszlo.
Armenian milk marketing cooperatives provide several benefits, of which the increased opportunity for milk marketing is valued most by member farmers. During the cooperative action milk production has also increased due to seminars on cattle feeding, artificial insemination, sanitation programs, and support by cooperatives in feed procurement. Another benefit is that through pooling products of specified grade or quality, marketing cooperatives are better able to market milk to large-scale buyers than individual owners. Putting their efforts together cooperatives can move to distant markets and thus expand their sales opportunities. This is of paramount importance for those cooperatives that have a sole buyer. In addition to milk marketing, almost all of...

Autores: Popovics,   Peter Andras.
The dramatic decline in consumption after 1990 was an important problem during the analysis of the sector. Even today, consumption is still below the degree that was before the political change, and significantly lags behind the EU level. The importance of this topic is emphasized by the fact that surplus milk could be marketed through the increased domestic consumption; this would create a more stable and calculable situation for farmers. Therefore, I considered it important to reveal what factors and by what shares influence the consumption of milk and dairy products. The relationship, time series and cross-sectional analysis based on national and international databases demonstrate the relationship between the consumption of milk and dairy products and...

Autores: Lehtonen,   Heikki.
We evaluate impacts of milk quota abolition in Finland where production costs and producer price of milk are among the highest in the EU. We analyse several price scenarios for dairy products corresponding to 10-30% reductions in raw milk prices in the EU following milk quota expansion of 2% per year. The sector model includes 18 dairy products and regions and other agricultural activities. Armington -assumption is used in modelling foreign trade. Trade of milk quotas and structural change are endogenous in the model. The results suggest that 10-15% reductions in the EU milk prices would result in less than 10% decrease in Finnish dairy production. Investments to large farm units would still increase. However, if the EU milk prices decreased by 15-20%...

Autores: Fuller,   Frank H.; Beghin,   John C.; Boland,   Michael A.; Babcock,   Bruce A.; Foster,   William E.
We assess the international competitiveness of the dairy industries in Argentina and Chile, combining recent market intelligence gathered from field visits with quantitative simulations of global policy reform scenarios. Both countries exhibit strong potential for export growth but face significant internal and external barriers to expanding their dairy industries. Global policy reforms would resolve some of the international obstacles to their expansion. Argentina has great potential, but it is handicapped by its current macroeconomic policies, trade policy distortions, and the uncertainty associated with policy implementation. Chile is more limited in terms of natural capacity for expansion, but it has a positive trade and investment environment.

Autores: Falkowski,   Jan; Malak-Rawlikowska,   Agata; Milczarek-Andrzejewska,   Dominika.
Taking into consideration a significant outflow of Polish farmers from dairy sector, we investigate what factors determine their decision to quit milk sales. We also analyse their current revenues and compare with that of similar households that remained in commercial milk production. Using logit model we find that severing relations with the market is mainly determined by worse endowment of farms with dairy specific assets, smaller cow herds and older age of the farm manager. Based on semi-parametric matching methods we find that in terms of revenues farms that decided for subsistence milk production perform worse than those that maintained commercial dairy business. However, more detailed analysis shows that this difference could be attributed to supply...

Organic milk production has been one of the fastest growing segments of organic agriculture in the United States in recent years. Despite the growing number of organic dairy operations, the characteristics of organic dairy operations and the relative costs of organic and conventional milk production have been difficult to analyze. This study, using 2005 ARMS data for U.S. dairy operations, which include a targeted sample of organic milk producers, examines the structure, costs, and challenges of organic milk production. The analysis addresses economies of size, regional differences, and pasture use in organic milk production and compares organic and conventional milk production costs. The findings suggest that economic forces have made organic operations...

Magyarország tejtermelése az EU-csatlakozást követően visszaesett. A többnyire alacsony átvételi árak és a szigorúbb minőségi követelmények miatt az elmúlt években sok tejtermelő kiszorult a piacról. A tej- és tejtermékek külkereskedelmében 2004 óta mind volumenben, mind értékben nettó importőri pozícióba kerültünk.  A tejkvóta-rendszer fokozatos kivezetése (a hazai kvóta kihasználtsága alig éri el a 85%-ot) a hazai tejágazatot közvetetten érintheti: a hatékonyabban ter¬melő tagállamok kerülhetnek előnybe a számunkra fontos olaszországi piacon, így értékesítési lehetőségeink szűkülhetnek, a hazai árakra még nagyobb nyomás nehezedhet.

Recently, several studies compared the performance of conventional and organic farms. Most studies concentrated on technical efficiency. In this paper we add to this literature by also comparing the scale efficiency of conventional and organic milk farms in Austria during the period 1997-2002. To do so we utilize a bilateral production frontier that includes both production technologies and Green’s (1995a,b) true fixed effects model to account for firm specific time-invariant heterogeneity and technical inefficiency. We find both groups of farms to be on average equally technical efficient (when compared to their production frontier), but conventional farms being on average considerably more scale efficient. However, while scale efficiency remained...

This paper attempts to identify factors which influence the effectiveness of milk production. The basic aim is to compare levels of costs in the dairy industry between Czech and European producers. The average cost per 100 kg ECM milk is determined from data provided by the European Dairy Farmers association (EDF). The total costs per 1 litre of Czech milk producers are on the European average level with high production efficiency. The problem is only in the utilisation of basic production factors, especially land and labour.

RESUMEN: La reestructuración que acompaña al régimen de cuotas en España, que pudo tener un sesgo más propio, sigue en sus resultados pautas de otros países de la UE. La trayectoria del proceso es similar a la de Alemania o Francia. Sin embargo, en cuanto al patrón para la gestión de las cuotas se ha venido inclinando hacia el esquema flexible del Reino Unido y Holanda, incluso regionalizando de facto el tráfico de cuotas, pues las transacciones entre CC.AA. están sometidas a fuertes limitaciones administrativas. En España el sistema de estado ha propiciado un escenario como el francés o el alemán, pero obtenido de esa gestión liberal de las cuotas según los modelos británico y holandés. Más que la desvinculación de cuota y tierra, han jugado los intereses...

Provedor de dados: 31
Autores: Strelecek,   Frantisek; Zdenek,   Radek; Lososova,   Jana.
This paper analyses the development of milk prices and effectiveness of holdings included in particular production category of Farm Accountancy Data Network “411 Milk” and their relations. The influence of prices on profitability, elasticity of production, effectiveness of long-term assets and resulting cost changes are discussed in particular. Milk profitability was not significantly influenced by different prices in individual states, but variation of prices in time was more important. The production is supposed to grow with delay. Milk yield and number of cows per worker are main determinants of labour productivity growth in in-kind expression. The influence of prices on labour productivity in monetary expression among individual states is not as...

Selected Results of the IFCN Dairy Network Milk Prices and Costs of Milk Production in 2003
Provedor de dados: 31
Autores: Hemme,   Torsten; Deeken,   Eva.
Within the IFCN Dairy Network milk prices and costs of milk production have been analysed from 31 countries for the year 2003. A wide diversity of milk prices between the countries could be observed with &gt; 35 US-$/100 kg milk in Switzerland, Norway and Canada and &lt; 15 US-$ in Argentina and Pakistan. Costs of milk production differ significantly between the countries, and within the countries as well. The highest costs of milk production (50 - 60 US- $/100 kg milk) are found in Switzerland and on average sized farms in the EU, the lowest costs in Argentina (10 – 15 US-$). For the future, a "world market price for milk," which was around 15 - 20 US-$/100 kg milk in 2003, is expected to be higher and might end at around 28 US-$.

Milk Production Strategies for Farmers in the EU Under New Policy Regulations
Provedor de dados: 31
Autores: Fuchs,   Clemens.
The recent reform of the agricultural policy in the EU provides totally new frame conditions for farmers. Main components of the reform are the decoupling of direct payments and particular for dairy farmers the reduction of intervention prices for milk products such as butter and SMP. The objective of this analysis is to develop strategies for dairy farmers considering the initial situation of four typical farm sizes at different productivity levels, debt-to-equity ratios and risk attitudes. The uncertainty of the price development for milk itself as well as for milk quotas will be covered using Monte Carlo simulations. Due to decreasing intervention prices profitability of milk production is endangered in most dairy farms and the values of assets will...

"Dairy sector reforms and transformation in Uganda since the 1990s
Provedor de dados: 31
Autores: Mbowa,   Swaibu; Shinyekwa,   Isaac; Lwanga,   Musa.
The Dairy sector in Uganda has responded positively to agricultural sector liberalisation policies that took effect in the 1990s. Total national milk production has grown from 460 million litres in 1990 to 1.6 billion litres in 2011, with per capita milk consumption growing from 16 litres in 1986to 58 litres by 2010. A variety of dairy products that were previously imported are now being produced locally in the country. Driven largely by dairy, the livestock sector has maintained positive growth rates averaging 3 percent per annum compared to the declining (and often negative) growth rates registered in the food and cash crop sub sectors. Milk production increased primarily from growth in cattle population, and secondarily from adoption of higher milk...

Forage Outsourcing in the Dairy Sector: The Extent of Use and Impact on Farm Profitability
Provedor de dados: 31
Autores: Gillespie,   Jeffrey M.; Nehring,   Richard F.; Sandretto,   Carmen L.; Hallahan,   Charles B.
The extent of forage purchasing behavior in milk production and its impact on profitability are analyzed using data from the 2000 and 2005 dairy versions of the Agricultural Resource Management Survey. Forage outsourcing is more common with hay than with silage and haylage, and is more prevalent in the western United States. Though silage and haylage outsourcing is found to impact profitability, the major profitability drivers appear to be farm size and efficiency. Evidence of significant forage contracting is found in the western United States.

EFICIÊNCIA TÉCNICA EM PROPRIEDADES LEITEIRAS DA MICRORREGIÃO DE VIÇOSA-MG: UMA ANÁLISE NÃO-PARAMÉTRICA
Provedor de dados: 31
Autores: Santos,   Jeronimo Alves dos; Vieira,   Wilson da Cruz; Baptista,   Antonio Jose Medina dos Santos.
The main objective of this paper was to evaluate the technical efficiency in 17 milk production farms in the region of Viçosa, state of Minas Gerais, during the period 1999-2002. These farms have received technical assistance from a program created by the Federal University of Viçosa and Nestlé. The technical efficiency was evaluated through the Data Envelopment Analysis (DEA) technique. The results obtained show that there are still a significant proportion of inefficient farms. It was also observed that the farms have become more homogeneous in their production characteristics which is probably due to the pattern of technical assistance adopted during the period analyzed.

Autores: Poncheki,Jessica Karina; Canha,Maria Luíza Schultz; Viechnieski,Sandro Luiz; Almeida,Rodrigo de.
The objective of this study was to describe daily body weight (BW) changes in the first 100 days of lactation in confined dairy cows and to associate BW loss with productive and reproductive performance. Data included 26,344 daily BW measurements of 372 Holsteins calving between June 2011 and June 2012 in a commercial herd in the South of Brazil. Cows were automatically weighed and were assigned according to parity. Individual measurements were smoothed using cubic splines, generating nadir BW, days to nadir BW and the BW loss (absolute and relative values). This approach used days in milk (DIM) as a single smoothing variable. Body weight at calving differed across parities: 570.5, 653.5, and 699.9 kg, for the 1st, 2nd and 3rd and subsequent parities,...

Autores: Oliveira,André Soares de; Campos,José Maurício de Souza; Lana,Rogério de Paula; Detmann,Edenio; Valadares Filho,Sebastião de Campos.
It was adopted in this work a methodology to estimate the optimal level of concentrate food for dairy cows on tropical pastures based on the theory of marginal analysis. An empiric model was developed and validated for application of the methodology using a database composed of 62 means of treatments from 32 studies in which milk production was evaluated regarded to the levels of concentrate feeding. Milk production (MP) showed quadratic behavior in response to concentrate intake (CI): MP (kg/cow/day) = 10.554 + 1.5855CI - 0.0552CI². Evaluation of the MP values observed over the predicted ones pointed the non-rejection of the null hypothesis, indicating that the model can be applied on the prediction of milk production, and consequently, on the optimal...

ABSTRACT Critical gaps exist in our understanding of the diagnostic reliability of subclinical mastitis tests in dromedary camels. Using a retrospective longitudinal cross-sectional approach, 191 lactating camels were randomly sampled from 47 camel herds to investigate at first the practicability of somatic cell count (SCC) and electrical conductivity (EC) tests as subclinical mastitis tests in camels through their validations by California mastitis test (CMT) score, and then through the subsequent employments of those objective means in assessing certain potential risk markers predisposing camels to this disease. Results indicate the reliability and validity of SCC test, in contrast to EC test, in distinguishing subclinical mastitic udders in camels, as...

Tropical pastures fertilized with nitrogen may have high crude protein (CP) contents with high rumen degradability. High crude protein concentrates offered to cows grazing these pastures may increase feed costs without positive effects on their performance. The objectives of this trial were to evaluate the effects of increasing metabolizable protein (MP) supply beyond the NRC (2001) recommendations for mid lactating dairy cows grazing elephant grass pasture (Pennisetum purpureum Schum. cv. Napier) managed with high stocking rates. Three concentrates (6.3 kg DM-1 cow-1 day-1) were evaluated: control (17%CP) was adjusted in relation to MP according to the NRC (2001); the other two contained extra soybean meal, to increase the CP content to 21.2% (CP) and...

Animal simulation models are sets of equations used to describe biological processes. A non-steady state simulation model of cattle digestion is presented in order to represent nutrient availability as a response to feed intake pattern and the kinetics of particle size reduction. Variables representing the particle size reduction and discontinuous voluntary feed intake were included in a mechanistic model created to optimize the supplementation of sugarcane based diets. In general the predicted values were very close to observed values for fibre and nitrogen flows. The model has not shown consistent bias in relation to the behavior of the observed data of duodenal flow of neutral detergent fiber and non-ammonia nitrogen. Milk production simulations were...

Abstract Thermal environment is recognized to be one the most important ecological factor to determine domestic animal growth, development and productivity for direct and indirect effects on its physiology and behavior. Despite having specific and individual adaptation, is very common, within seasonal or diurnal temperature variations, animals deal with situations outside their thermal comfort zone. Due to heat stress, dairy cows reduce milk production and fertility, and therefore, had achieved an increasing in metabolic disorders incidence, causing low revenues to farm in short and medium periods. Due to world climate change more impact of the meteorological variables on animal responses is expected for the future. This study aimed to describe and...

This study aimed to evaluate the effect of corn silage (CS) replacement by cassava's foliage silage (CFS) on the production and quality of milk. Twelve lactating dairy cows were used in a randomized block experimental design with four treatments and three repetitions per block. CS was replaced by CFS at the levels of 0, 20, 40, and 60%. The replacement of CS by different levels of CFS had very low effect on the variables studied. Milk density decreased when the replacement level was increased. Fatty acids 4:0 and 6:0 presented a quadratic behavior, while fat acids 8:0, 10:0, and 15:0 presented a linear behavior as their concentrations fell when CFS diet content was increased. The CS replacement by 20% until 60% CFS resulted a significant decrease in the...

Nutritional Strategies to Improve Nitrogen use Efficiency by Grazing Dairy Cows
Provedor de dados: 117
Autores: Keim,Juan Pablo; Anrique,René.
Grazing dairy cows are characterized by converting a low proportion of dietary N into milk N. This low N use efficiency (NUE) is mainly due to an excessive supply of crude protein (CP) of pasture with regard to animal requirements. Excess N in the diet has negative effects for the animal; it alters the organoleptic characteristics of milk and pollutes the environment through N excretions. The aim of this review was to analyze the available information on nutritional strategies to improve NUE by grazing dairy cows, such as diluting the dietary N through supplementation, synchronizing ruminal carbohydrate (CHO), and N fermentation rates, and using pastures with a high water soluble carbohydrates (WSC) content. There is a beneficial effect of carbohydrate...

ABSTRACT: The aim of this study was to evaluate the effect of total replacement of raw whole soybean (RAW) for roastedwhole soybean (ROS) on the production performance of Holstein cows. Two experiments were carried out usinga simple reversal design where RAW has been completely replaced by ROS. In experiment 1, 22 cows (175±60 days in milk)were used, and the dietary inclusion level of RAW or ROS was 3.7% of dry matter (DM). In experiment 2, 16 cows (130±50 days in milk)were used, and thedietary inclusion level of RAW or ROS was 11% of DM. In both experiments, ROS increased milk production by 1.1kgday-1 without changing fat and protein production. Dry matter intake or milk urea nitrogenwere not affected by dietary soy source. In experiment 2, plasma glucose...

The work was developed in the experimental station of Embrapa Gado de Leite (Dairy Cattle Embrapa), in Coronel Pacheco, in Zona da Mata Region of Minas Gerais, with the purpose of evaluating the productive performance of Holstein cows kept on 'Coast-cross' (Cynodon dactylon (L.) Pears) pasture, fertilized, strategically irrigated and where the cows were daily supplemented with 3 or 6 kg of concentrate/cow/day. The data were collected during three years (October/2000 to October/2003), involving 108 lactations. An experimental randomized block design with two replicate areas per treatment was adopted, with nine animals per area and eighteen animals per treatment being utilized, with fixed stocking rate of five cows/ha. The system of grazing, under rotated...
