Energy Requirements of Zebu Beef Cattle
Projections for beef cattle production in Brazil for the next 10 years forecast an annual increase of about 3.5%. For the same period, a 2.22% growth in the domestic intake of beef cattle and an increase of 3.07% a year in exportation is estimated. This annual increase in exportation could reach 3.4 million tons by 2019, establishing Brazil as the main beef exporting country (MAPA/AGE, 2009). T...
متن کاملPrediction of enteric methane emissions from cattle.
Agriculture has a key role in food production worldwide and it is a major component of the gross domestic product of several countries. Livestock production is essential for the generation of high quality protein foods and the delivery of foods in regions where animal products are the main food source. Environmental impacts of livestock production have been examined for decades, but recently em...
متن کاملEffect of Feeding Total Mixed Ration on Methane Emission and Energy Metabolism in Crossbred Cattle and Buffaloes
This study evaluates the nutrients digestibility and energy metabolism of crossbred cattle and buffaloes fed different ratio of concentrate and roughage based ration. 12 adult animals were used of three groups of cattle and buffalo, the following: cattle (Bos taurus × Bos indicus) (n=6) and buffalo (Bubalus bubalis) (n=6). Three groups of animals, each consisting two crossbred cattle, and two b...
متن کاملPrediction of methane energy output in dairy and beef cattle offered grass silage-based diets
Since 1992 a number of lactating dairy cows (n 5 247) and beef steers (n 5 75) were offered grass silage-based diets in a range of feeding experiments and subjected to gaseous exchange measurements in calorimetric chambers at the Agricultural Research Institute of Northern Ireland. The objective of the present study was therefore to use the energy metabolism data from these studies to evaluate ...
متن کاملThe potential of 3-nitrooxypropanol to lower enteric methane emissions from beef cattle.
This study evaluated if 3-nitrooxypropanol reduces enteric methane (CH4) emissions when added to the diet of beef cattle. The effects of 3-nitrooxypropanol on related variables including diet digestibility, ruminal fermentation, and ruminal microorganisms were also investigated. Eight ruminally cannulated Angus heifers (549 ± 64.3 kg [mean BW ± SD]) were fed a high forage diet (backgrounding di...
