Emisiones de metano generadas por excretas de animales de granja y contenido ruminal de bovino.
Provedor de dados: 32
Autores: Ramírez Hernández, Irma Fabiola.
Las emisiones de metano (CH4) de las actividades ganaderas, como un gas de efecto invernadero, son estimadas para el desarrollo de inventarios. Sin embargo el aprovechamiento de la producción del CH4 a partir de excretas de animales rumiantes y no rumiantes, para la generación de energía, requiere de establecer condiciones de temperatura y humedad para eficientar la mayor producción de este gas, compuesto del biogás producido por la actividad microbiana. En este estudio, se desarrollaron cuatro experimentos para cuantificar la producción de CH4, con la fermentación controlada, en un sistema biorreactor-trampa. En el 1er experimento, se compararon diferentes excretas de animales rumiantes: estiércol de ganado lechero y en engorda, excretas de cabras y...

Autores: VOLPI, D.; ALVES, F. V.; SARAIVA, E. F.; VIGAS, V. P.; ARGUELHO, A. da S.; ZOPOLLATTO, M.; ALMEIDA, R. G. de.
A observação visual do comportamento ingestivo em ruminantes, principalmente naqueles mantidos em pastagens, apesar de comumente utilizada com diferentes finalidades de estudo, é trabalhosa, pouca precisa e empenha grande quantidade de mão-de-obra. Com o avanço da tecnologia em geral, outras metodologias, que fazem uso de sensores mecânicos, ópticos e sonoros, mostram grande potencial de uso em ruminantes. A bioacústica, em particular, adequa-se em experimentos que necessitam tanto de macro quanto de microatividades, otimizando mão-de-obra e com custo relativamente baixo em comparação à outras metodologias automatizadas. Entretanto, por ser um campo de estudo recente na produção animal, as operações de captura e análise dos sons ainda precisam ser...

Control of Footrot in Small Ruminants of Nepal
Provedor de dados: 31
Autores: McLeod,   Ross.
Footrot, a bacterial disease which attacks the feet of sheep and goats causing lameness and high levels of flock mortality, was endemic in the western districts of Nepal. As a result of the collaborative efforts between Nepalese, Australian and British scientists within ACIAR projects AS2/1991/017 and AS2/1996/021, the virulent form of this disease has been eradicated from the livestock industries of the country. The economic benefits stemming from this achievement are described and quantified in this report. Over the 1993–2022 period, ACIAR invested $A1.5 million in research designed to improve the management of footrot in Nepal. Based on levels of disease prevalence reported at the beginning of the projects and a probability of the disease spreading to...

Disaggregate Productivity Growth in Livestock Production: A Directional Malmquist Index Approach
Provedor de dados: 31
Autores: Ludena,   Carlos E.; Hertel,   Thomas W.; Preckel,   Paul V.; Foster,   Kenneth A.; Nin Pratt,   Alejandro.
Limited data on the allocation of inputs to different activities has limited agricultural economists' attempts to measure sub-sector productivity growth in agriculture. However, recent developments have enabled us to estimate total factor productivity (TFP) growth for crops and livestock accounting for input-output allocation. This paper extends previous work on TFP measurement for livestock into ruminants and non-ruminant productivity measurement, given the differences in productivity growth rates among these species. The results show that the non-ruminant sector is more dynamic than the ruminant sector, driving most of the productivity growth within the livestock sector. Given the rapid rates of productivity growth observed recently, non-ruminant...

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...

Provedor de dados: 96
Autores: Henrique,Douglas Sampaio; Vieira,Ricardo Augusto Mendonça; Malafaia,Pedro Antônio Muniz; Mancini,Maurício Cordeiro; Gonçalves,André Luigi.
Data of 320 animals were obtained from eight comparative slaughter studies performed under tropical conditions and used to estimate the total efficiency of utilization of the metabolizable energy intake (MEI), which varied from 77 to 419 kcal kg-0.75d-1. The provided data also contained direct measures of the recovered energy (RE), which allowed calculating the heat production (HE) by difference. The RE was regressed on MEI and deviations from linearity were evaluated by using the F-test. The respective estimates of the fasting heat production and the intercept and the slope that composes the relationship between RE and MEI were 73 kcal kg-0.75d-1, 42 kcal kg-0.75d-1 and 0.37. Hence, the total efficiency was estimated by dividing the net energy for...

The intake of the dry matter (DM), the crude protein (CP) and the metabolizable energy intake (ME) in megacalories per day (Mcal/day) were not affected by the diets. In contrast, the intake of neutral detergent fiber (NDF), in g/kg BW, increased linearly. An increasing linear effect was also observed for the ether extract (EE) intake, whereas a decreasing linear performance was observed for the non-fibrous carbohydrate (NFC) intake. The digestibility of DM, organic matter and NFC decreased linearly with the sunflower cake inclusion, whereas the digestibility of CP, NDF, and EE were not influenced by the diets. No effect was observed for the concentration of serum glucose or urea nitrogen serum. No effect was observed on the urea nitrogen serum in the hours...

Autores: Henrique,Douglas Sampaio; Lana,Rogério de Paula; Vieira,Ricardo Augusto Mendonça; Fontes,Carlos Augusto de Alencar; Botelho,Mosar Faria.
A mathematical model based on Cornell Net Carbohydrate and Protein System (CNCPS) was developed and adapted in order to evaluate beef cattle rations at tropical climate conditions. The presented system differs from CNCPS in the modeling of insoluble particles' digestion and passage kinetics, which enabled the estimation of fiber mass in rumen and its effects on animal performance. The equations used to estimate metabolizable protein and net energy requirements for gain, net energy requirement for maintenance and total efficiency of metabolizable energy utilization were obtained from scientific articles published in Brazil. The parameters of the regression equations in these papers were estimated using data from Bos indicus purebred and crossbred animals...

Impact of dietary manipulation on nutrient flows and greenhouse gas emissions in cattle
Provedor de dados: 96
Autores: Kebreab,Ermias; Strathe,Anders; Fadel,James; Moraes,Luis; France,James.
The growing global demand for meat and particularly in countries such as Brazil is expected to increase intensive animal production. Consequently the main pollutants of interest are nitrogen (N), phosphorus (P) and greenhouse gases (GHG). Nitrogen can be a problem through nitrate leaching to water bodies, ammonia, and nitrous oxide emissions to air. Phosphorus loading in soil from manure application can be the main issue due to the tendency of P to accumulate in soil and leach to groundwater and rivers. The sources of agricultural GHG emissions include methane from enteric fermentation, manure storage and spreading, and nitrous oxide mainly from application of manure on land. Dietary manipulation has proven to be an effective tool to reduce...

Provedor de dados: 96
Autores: Tedeschi,Luis Orlindo; Fox,Danny Gene; Fonseca,Mozart Alves; Cavalcanti,Luigi Francis Lima.
Protein supply and requirements by ruminants have been studied for more than a century. These studies led to the accumulation of lots of scientific information about digestion and metabolism of protein by ruminants as well as the characterization of the dietary protein in order to maximize animal performance. During the 1980s and 1990s, when computers became more accessible and powerful, scientists began to conceptualize and develop mathematical nutrition models, and to program them into computers to assist with ration balancing and formulation for domesticated ruminants, specifically dairy and beef cattle. The most commonly known nutrition models developed during this period were the National Research Council (NRC) in the United States, Agricultural...

Nowadays consumers are highly interested in the quality of the products they eat, especially when this refers to meat. Consumption of meat from ruminant animals and its derivatives is on the increase, particularly in some countries such as Brazil, one of the main beef exporters in the world. Current analysis is a review of the different factors that affect meat quality in ruminants, with a focus on sensory analyses. Some factors throughout the entire meat chain are analyzed, or rather, from those that producers underscore to improve the quality of their products to those related with consumers' habits and beliefs. Most of the papers reviewed have been developed by researchers involved in the Meat Quality and Technology Group (University of Zaragoza and...

G.L. Arzate-Vázquez, F.A. Castrejón-Pineda, R. Rosiles-Martínez, S. Carrillo-Pita, S. Angeles-Campos, and E. Vargas-Bello-Pérez. 2016. Effect of genus and growth stage on the chemical and mineral composition of tropical grasses used to feed dairy cows. Cien. Inv. Agr. 43(3): 476-485. In tropical production systems, dairy cows are rarely supplemented with minerals, which often lead to mineral imbalances. Grasses grown together in the same soil type and sampled at the same growth stage can vary widely in chemical and mineral composition; therefore, the objective of this study was to characterize the chemical and mineral composition of Urochloa spp., Megathyrsus spp., and Andropogon spp. at three different stages of growth in the same soil type.

The objective of this research was to evaluate the in vitro degradability and gas production from different byproducts of the domestic biodiesel industry (Glycine max, Brassica napus L., Helianthus annuus and Raphanus sativus L.) using four increasing levels (0, 30, 50 and 70%) of replacement of Pennisetum purpureum. The inoculum for the in vitro incubations was obtained from three Holstein cows with rumen fistulas. Gas production was measured at 3, 6, 12, 24 and 48 hours of incubation. The experimental design was a completely randomized 4 × 4 factorial arrangement, with byproducts and their levels being the factors. The results showed a significant effect (P &amp;#8804; 0.05) of all byproducts. A higher level of degradation was observed following 48 hours...

We report exogenous pigmentation in sheep grazing in native pastures in northeastern Brazil. The sheep carcasses from a farm were condemned at the slaughterhouse due to pigmentation of the carcasses and viscera. In visits to the farm, bluish-purple pigmentation of the mucosa was observed in the sheep. In two necropsied sheep, a bluish-purple pigment was observed in the skin, subcutaneous tissue, fat, muscles, cartilage, bones, serous membranes of the forestomachs, kidneys, adrenal glands, and the mucosa of the uterus, urinary bladder, urethra, vagina, trachea, bronchi, and bronchioles. Some bone surfaces, the intima of large arteries, tendons, muscle insertions, and ligaments had a yellow-brown or light brown pigment. However, the pigment was not observed...

ABSTRACT:  Swainsonine-containing plants comprise a group of important poisonous plants in Brazil. This research aimed to characterize both the behavioral changes related to reproduction and appearance of lesions in the reproductive system of bucks poisoned by Ipomoea brasiliana. I. brasiliana plants were collected and administered at a dose of 4g/kg (800µg swainsonine/kg) to two groups of bucks for 45 days. Goats from Group I were euthanized on the 46th day of the experiment, and goats from Group II were euthanized on the 120th day. Group III was composed of goats that did not receive I. brasiliana and were euthanized on the 120th day of the experiment. Reproductive behavioral changes were observed starting on day 20 and were characterized by an absence...

Autores: Martinele,Isabel; Paiva,Paulo César de Aguiar; Lopes,Fernando César Ferraz; Pereira,Juliana de Cássia; Ferreira,Ludhiana Rosa.
The aim of this study was to evaluate ruminal in situ degradability and in vitro digestibility of dry matter (DM) in concentrate supplements containing diverse potato flour pelletized with urea (0%, 4%, 8%, and 12% DM). Samples of feeds were incubated for 0, 2, 4, 8, 12, 24, 36, and 48h in the rumen of four fistulated sheep. Level of urea added had no significant effect (P&gt;;0.05) on the soluble fraction (a) or potentially degradable fraction (b) of the pellets and ranged from 2.1% to 12.2% and 72.9% to 87.5%, respectively. Quadratic effects (P=0.03) of the rate of degradation of fraction "b" ranged from 4.75% h-1to 7.39% h-1; the estimated maximum value at 7.4% h-1was obtained when 5.9% urea was added to the pellet. Quadratic effects (P≤0.02) of the...

ABSTRACT: This report aimed to describe a case of peripheral neuropathy in a copper-deficient goat, and highlights the clinical, and pathological features of the disease. The goat had low body score, hyporexia, alopecia, achromotrichia, left hindlimb protraction, paralysis with dragging of digit and difficulty to stand up and microcytic normochromic anemia. Copper concentration in serum was markedly lower (2.0µmol L-1) whereas the iron serum content was significantly increased (51.0µmol L-1). The main gross alteration was the reduction of the quadriceps vastus laterallis muscle volume. Histologically, there was atrophy of the quadriceps vastus laterallis muscle and presence of satellite cells, infiltration of lymphocytes, macrophages and replacement of the...
