چکیده
The objective of this study was to evaluate the effect different pasture systems on beef steers’ performance, dry matter intake, enteric methane emission, carcass production, forage quality, and animal production per hectare (ha). trial conducted at Embrapa Southeast Livestock, São Carlos/SP, Brazil. Sixty Cachim steers (5/8 Charolais × 3/8 Zebu) with initial liveweights 255 ± 7 kg were evaluated for two years under five grazing (EXT = Extensive; INT Intensive; iCL Integrated crop livestock; iCLF livestock forest; iLF forest). final liveweight greater (p < 0.05) animals (484 51 466 79 kg, respectively) compared in iCLF, EXT (416 57, 414 50 429 48 kg). intake significantly system than it (9.8 2.1 7.5 2.9 day?1). Regarding emission intensity relation gain unit area (g CH4 LWG?1 ha?1 year?1), differed among 1.6; 0.6; 0.8; ICLF 1.1; ILF 0.7). Similarly, (kg kg?1 carcass; 0.496; 0.250; 0.297; 0.345; 0.286). Beef cattle that are raised intensive and/or integrated have a availability mass nutrients those extensively. Pasture undergo soil pH correction fertilization, rotational maize cropping produce average daily liveweights, thereby lessening emissions weight gain. In these systems, efficiency terms land is also greater, however, forest component (iLF iCLF) equal system. same pattern observed as area.

Prediction 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 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...
متن کاملCan live weight be used as a proxy for enteric methane emissions from pasture-fed sheep?
To test the hypothesis that sheep live weight (LW) could be used to improve enteric methane (CH4) emission calculations, mature ewes of 4 different breeds representative of the UK sheep industry were studied: Welsh Mountain, Scottish Blackface, Welsh Mule and Texel (n = 8 per breed). The ewes were housed and offered ad libitum access to fresh cut pasture of three different types, varying in dig...
متن کاملMethane emissions from cattle.
Increasing atmospheric concentrations of methane have led scientists to examine its sources of origin. Ruminant livestock can produce 250 to 500 L of methane per day. This level of production results in estimates of the contribution by cattle to global warming that may occur in the next 50 to 100 yr to be a little less than 2%. Many factors influence methane emissions from cattle and include th...
