Digestion of Protein. in the Intestines of the Sheep
نویسنده
چکیده
Studies have been made of the digestion of nitrogen (N) and of organic matter (OM) in sheep offered thirteen gramineous roughages of widely differing nutritive value. It was concluded that the true digestibility of crude protein in the intestines ranged from 74 to 82% (mean 78%). These estimates were based on observations that, while metabolic faecal N (MFN) was equal to 0.4 g/100 g OM intake, less than one third of the MFN came from endogenous secretion into the intestines. The intestinal component of MFN was equal to 0.18 g/100 g OM leaving the stomach. The possible use of this information in studying protein digestion in grazing sheep is discussed.

Effect of Dietary Protein Supplementation on Sheep Milk Coagulation Properties
The objectives of this experiment were to evaluate the effects of dietary protein supplementation in lactating dairy ewe’s diets on milk coagulation properties. Milk samples (n=126) were analyzed to assess the source of variation for rennet coagulation ability at the 6th (RCA6) and 12th hour (RCA12), milk clotting time (MCT, s) and an index of milk clotting time (IMCT, %). In addition, data wer...

The aim of present experiment was to investigate the feeding value of wild pistachio leaf (khinjuk leaf, KL) for Arabi sheep. The digestibility and fermentation of diets containing different amounts of khinjuk (0, 5, 10, 15, 20, 25 and 30%) were measured. Then, the effect of presence of KL in the diet and its tannin content on the digestibility of alfalfa hay (Alfa), wheat straw (WS) and soybea...

متن کاملGenetic diversity of myostatin and calpastatin genes in Zandi sheep
Myostatin (MSTN) is an inhibitor of skeletal muscle growth, and a mutation in the gene coding region leads to increased muscling. Calpastatin (CAST) is a specific inhibitor of the ubiquitous calcium-dependent proteases, µ-calpain and m-calpain, found in mammalian tissues. In this study, genomic DNA was extracted from Zandi sheep blood samples. Gel monitoring and spectrophotometer methods were u...
