This paper uses the spatial analysis tools DIVA and FloraMap to identify potential areas for the in situ conservation of a set of 10 forage species. We introduce the idea of roadside verges as conservation areas and discuss the risks and opportunities of two potential scenarios for conservation. These are the introduction of mass reservoirs outside of the original areas of collection and conservation inside the area of origin. Four potential areas for in situ conservation in Latin America are identified. Although more detailed studies using remote sensing, soil information, and field reconnaissance will be necessary for a final assessment of the suggested areas as field conservation sites, we discuss the possibilities of establishing low-maintenance...

Forrageiras: principais fatores de antiqualidade.
Provedor de dados: 14
Autores: JERBA, V. de F.; MEDEIROS, S. R. de; FERNANDES, C. D.
A pecuária brasileira baseada em pastagens é uma das atividades econômicas mais importantes do Brasil, portanto são necessárias a manutenção e a ampliação de programas de melhoramento genético de forrageiras. Além de observar o desempenho agronômico do vegetal, é importante a determinação do seu valor nutritivo. Essa última característica é comumente determinada por análises bromatológicoas, mas, no entanto, existem fatores que limitam a ingestão e a digestão das forrageins que não são determinadas pelas análises convencionais, os quais são denominados de antiqualidade ou antinutricionais, os quais projudicam até mesmo a aceitabilidade da forragem pelos animais. Os fatores de antiqualidade são de natureza quimica ou estrutural, podendo ser determinados em...

An Exploratory Assessment of the Economic Impact of Forage Options for Beef Production on Smallholder Farms in the Red Soils Region of China
Provedor de dados: 31
Autores: MacLeod,   Neil D.; Wen,   Shilin; Hu,   Mingwen.
The rapidly growing beef cattle herd of the Peoples Republic of China is largely carried as small numbers of animals on smallholder farms. These enterprises have traditionally focussed on cereal and vegetable crops. Limited plantings of specialised forages combined with a poor knowledge of ruminant nutrition by sm allholder farmers represent a serious challenge to establishing genuinely sustainable beef enterprises for this sector. Government policy to promote beef cattle production on smallholder farms is now focussing on the use of new forages and improved feeding practices. The paper draws on some economic insights from an Australian Centre for International Agricultural Research (ACIAR) project that is exploring options for integrating the planting and...

Agricultural research in INIFAP (National Institute for Agricultural, Livestock and Forestry Research of Mexico) has been traditionally oriented to increase yields. Under this approach research objectives have been directed to obtain more kilograms of grains per hectare, more milk liters per cow, more meat per animal, etc. As national and international agricultural context has been changed, new approaches have been included and topics like environment and market trends are now incorporated to INIFAP's research activity. The market approach has been taken into account in an implicit way in some research projects of INIFAP. However, it is necessary to pay more attention to this topic because as it is known, consumers orient type and characteristics of goods...

Did farmers’ livelihood improve? An impact assessment of incorporating forages into the crop-livestock system in the coastal savannah zone of Ghana
Provedor de dados: 31
Autores: Ameleke,   G.Y.; Okantah,   S.A.; Sottie,   E.T.; Marfo-Ahenkora,   E.A.; Aboe,   P.A.T.
The study used programming methods to assess the farm-level impact of incorporating forages, including dual purpose Cajanus cajan (C. cajan), into the crop-livestock system in the Coastal Savannah Zone of Ghana. The system was modeled in GAMS and solved using linear programming. The optimal enterprise mixes and their resultant net revenues with and without the interventions and therefore the change in net revenue were obtained. The intervention was to grow forages as part of the crop-livestock system and feed them to milking cows and their calves for increased milk production and growth. The grain of the forage was used as food by the farmers, and manure from the animals was also used for crop production. The effect of policy options like educating farmers...

Forage based animal production systems and sustainability, an invited keynote
Provedor de dados: 96
Autores: Chaudhry,Abdul Shakoor.
Forages are essential for the successful operation of animal production systems. This is more relevant to ruminants which are heavily dependant upon forages for their health and production in a cost-effective and sustainable manner. While forages are an economical source of nutrients for animal production, they also help conserve the soil integrity, water supply and air quality. Although the role of these forages for animal production could vary depending upon the regional preferences for the animal and forage species, climate and resources, their importance in the success of ruminant production is acknowledged. However with the increasing global human population and urbanisation, the sustainability of forage based animal production systems is sometimes...

Alkanes as markers in nutritional studies with wild ruminant and non-ruminant animals
Provedor de dados: 63
Autores: Oliveira,Dimas Estrasulas de; Silva,Sila Carneiro da.
Knowledge of information relative to the digestibility, intake and botanical and morphological composition of the diet is important in nutritional studies, since it provides the basis for understanding aspects related to the ingestive behavior and selectivity of animals. N-alkanes have been used successfully as markers in studies with many species of animals, particularly domesticated ruminants, most of the times as replacements for conventional markers as chromium oxide for example. However, for wild ruminants and non-ruminant animals information on this technique is still scarce and, as a consequence, its potential for use unknown. This review reports the use of this technique in studies of feed digestibility, intake and diet composition with wild...

Mechanical maceration enhances site and extent of digestion of low-moisture, low-quality forages. Four Holstein steers (172 ± 8 kg) with cannulas in rumen and proximal duodenum were used in 4x4 Latin square design to evaluate the process of mechanical maceration of sudangrass hay on the characteristics of ruminal and total tract digestion. Treatments consisted of a steam-flaked corn-based growing diet supplemented with 21 % forage (DM basis) as: i) wheat straw (Triticum aestivum, STRW), ii) sudangrass hay (Sorghum sudanense, SG), iii) macerated SG at intensity of 4,134 kPa (MAC600) and 4) macerated SG at intensity of 6,200 kPa (MAC900). All forages were ground to pass through a 3.8 cm screen before incorporation into complete mixed diets (21:79 forage to...

Provedor de dados: 115
Autores: Huerta-Treviño,Alejandra; Dávila-Aviña,Jorge E.; Sánchez,Eduardo; Heredia,Norma; García,Santos.
Abstract Mycotoxins are secondary metabolites produced by specific filamentous fungi that are common contaminants of agricultural commodities. These compounds are toxic to humans and animals, and they are a health problem worldwide. Mycotoxin-containing feeds can cause serious diseases in farm animals and substantial economic losses. Therefore, the objective of this study was to determine the occurrence and levels of six mycotoxins in three types of forage at retail in the state of Nuevo León, México. The hypothesis was that all types of forages were contaminated with at least one of the six mycotoxins analyzed. One hundred and twenty samples of alfalfa (Medicago sativa L.), sorghum [Sorghum bicolor (L.) Moench], and grass (Cenchrus ciliaris L.) used for...

Autores: Brighenti,Alexandre Magno; Benites,Flávio Rodrigo Gandolfi; Souza Sobrinho,Fausto.
ABSTRACT Cynodon nlemfuensis Vanderyst, commonly called African star grass, is excellent forage in pasture formation and herd feeding. However, little information is available regarding weed management in areas of star grasses. Two field experiments were carried out in 2017 and 2018 to evaluate the response of African star grass to postemergence herbicides. The treatments applied were as follows: 2,4-D (1,340.0 g ae ha-1); 2,4-D + picloram (720.0 +192.0 g ae ha-1 + 0.3% v/v nonionic surfactant); fluroxypyr + picloram (80.0 + 80.0 g ae ha-1 + 0.3% v/v mineral oil); fluroxypyr + aminopyralid (160.0 + 80.0 g ae ha-1 + 0.3% v/v mineral oil); fluroxypyr + triclopyr (320.0 + 960.0 g ae ha-1 + 0.3% v/v mineral oil); bentazon (720.0 g ai ha-1 + 0.5% v/v mineral...
