Planning forage needs in beef cattle enterprises is necessary for efficient utilization of genetic and environmental resources in pastoral systems and to generate economic benefits in an environmentally sound way. Production risk evaluation is essential in feed planning for cow-calf operations in pastoral systems. The proposed method to accomplish with production risk in these systems is based on the time biological system is maintained in an acceptable state under adverse climate conditions. This is coined "buffering time". The buffering time is calculated for both animals and pasture using an energetic approach. For cows, the buffering time is the minimum period the animal takes to reach the lowest acceptable body weight. for pasture, it is period for herbage mass to decrease to its mininum acceptable pasture buffering time indicated that increasing stocking rates put grazing systems at a higher risk. |

Abstract: Currently, due to environmental and economic issues, ruminant production system has aimed at maximizing production, concomitant with an increased efficiency. Because of methane is produced in the process of feed energy utilization within the animal, its reduction is usually associated with improved productivity. Therefore, one of the strategies to optimizing energy use in ruminants is to minimize enteric methane (CH4) emission during the fermentation process, by reducing dry matter intake (Shibata and Terada, 2010). Feed restriction is a common practice on goat production in several parts of world, and can be used to exploiting the compensatory gain, resulting in better efficiency of animal feed energy utilization. Therefore, this study was carried out to evaluate the effect of feed restriction on methane emission and digestibility. |
