Utilization of Date by Product on Sheep Feeding: Its Ruminal Degradation, Nutrient Digestibility and Its Effect on Sheep Growth
This study was conducted in two separate experiments. Four rumen-cannulated sheep were allocated in the first experiment to evaluate date by-product (DBP) and date seed (DS) nutrients degradation in rumen. In experiment two eighteen fattening lambs were allocated in three different treatments (6 animals/treatment) to evaluate DBP effects on animal performance and nutrients’ digestibility. Three...
متن کاملAcetate utilization in sheep.
Acetate, an important metabolite in most species, has a unique place in ruminant metabolism. As the major product of ruminal and caecal fermentation, acetate provides much of the energy requirements of ruminant tissues. Little information is available, however, on the overall utilization of acetate in sheep. Intravenous-acetate tolerance tests in sheep (Jarrett, Potter & Filsell, 1952; Pugh & S...
متن کاملUtilization of Sweet Sorghum Juice for Efficient 2,3-Butanediol Production by Serratia marcescens H30
Sweet sorghum juice (SSJ) is considered a good carbon source for biorefinery due to its low price and high fermentable-sugar content. In this study, 2,3-butanediol (2,3-BD) production from SSJ by Serratia marcescens H30 was investigated. First, the medium compositions including the contents of SSJ, nitrogen source, and mineral salts were optimized in conical flasks using a single factor and ort...
متن کاملNet utilization of roughage and concentrate diets by sheep.
1. Two diets, an all-roughage diet and a high-concentrate diet, were fed at two levels, a low level of estimated 1-5 times maintenance energy requirement and a higher level of estimated two times maintenance energy requirement, to South African Mutton Merino castrated male sheep, aged 13 months and in fairly lean condition at the start of the 93 d experimental period. 2. Body composition and en...
متن کاملThe Utilization of Ammonia-Nitrogen by the Sheep
Ammonia plays a central role in the nitrogen metabolism of the rumen; essentially, this is due, on the one hand, to its origin from the deamination of proteins and other nitrogenous substances and from the hydrolysis of urea, and on the other hand to its use by ruminal bacteria as a source of nitrogen for growth. Ammonia is absorbed from the rumen and converted in the liver to urea, which in pa...
