The nutrient digestibility, nitrogen balance and in vivo metabolizable energy supply of Mucuna pruriens whole pods fed to growing Pelibuey lambs was investigated. Eight Pelibuey sheep housed in metabolic crates were fed increasing levels of Mucuna pruriens pods: 0 (control), 100 (Mucuna100), 200 (Mucuna200) and 300 (Mucuna300) g/kg dry matter. A quadratic (p<0.002) effect was observed for dry m...

Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...

Component models were developed to predict the net efficiency of ME utilization for gain in cattle and to predict daily gain using recovered energy as the input. These models were integrated into a single model to predict daily gain from ME available for gain. One component model predicts the net efficiency of ME utilization for gain using constant partial net efficiencies of 0.2 and 0.75 for M...

A total number of 156 laying chickens at 29 weeks of age were used in the study. Birds were distributed equally in two dietary energy levels (2600 and 2900 Kcal ME/Kg feed) and three strains viz., Lohmann Selected Leghorn (LSL), Fayoumi and Dandarawi. Three experiments were conducted to measure energy partitioning values (36 birds), liver oxygen consumption and oxygen consumption of epithelium ...

For both period and cumulative growth performance data, there were trends for increased feed intake and increased feed to gain ratios associated with increasing concentrations of dietary clinoptilolite. If, however, efficiency was expressed as daily intake of megacalories of metabolizable energy, there were no treatment effects. This lack of treatment response is illustrated by overall cumulati...
