40 percent of annual production costs in typical cow/calf operations. These costs also have a dramatic impact on cost per unit of gain in stocker operations. Consequently, cattle producers must continually evaluate new methods to make efficient use of available resources while optimizing animal performance and minimizing supplementation costs. Often, when cattle graze marginal to low quality fo...

Abstract Following recent arguments that cultural practices in wild animal populations have important conservation implications, we argue recognizing captive animals as has welfare implications. Having a culture is of deep importance for animals, wherever they live. Without understanding the capacities will be left with deeply impoverished view what need to flourish. Best should therefore requi...

The objective of this paper was to review recent studies on nutrient synchrony and the effects of synchronization of energy and N supply in the rumen on nitrogen utilization and animal performance. Theoretically, synchronization of energy and N supply in the rumen should allow more efficient use of nutrients by rumen microbes, increase microbial protein and fermentation end products, and thus i...

Twenty seven lambs were used to investigate the effects of the inclusion of 4% hydrogenated palm oil (HPO) or sunflower oil (SFO) in the concentrate on feed intake, animal performance and fatty acid composition. Animals (16.2±0.27 kg initial weight) were fed concentrate (Control, HPO or SFO) and barley straw ad libitum and slaughtered at 25 kg. Vegetable oils did not affect (P>0.05) feed intake...
