The evaluation of foodstuffs provides the animal nutritionists with necessary information to adjust the diet from a physiological and economic point of view, so that the animal performance be desirable. Nowadays, there are various methods for evaluating ruminant feed intake. One of the most important methods is in situ nylon bag technique. Prosopis farcta is one of plants which is used as forag...

This study was conducted to evaluate the ensiling characteristics and the in situ degradability of a by-product feed (BF)-based silage. Before ensilation, the BF-based mixture was composed of 50% spent mushroom substrate, 21% recycled poultry bedding, 15% ryegrass straw, 10.8% rice bran, 2% molasses, 0.6% bentonite, and 0.6% microbial inoculant on a wet basis and ensiled for up to 4 weeks. The ...

Three techniques for estimating rumen protein degradability were used together with in vivo apparent nitrogen digestibility estimates from sheep fed dried chopped Pangola grass or Siratro. The techniques used were 1) nitrogen disappearance from nylon bags suspended in the rumen, 2) S labelling of rumen microbial protein with plant nitrogen degradability calculated as the difference between micr...

in order to determination of ileum apparent and true digestibility of two samples of poultry by product meal, an experiment was conducted with a total of 60 day-old broiler chicks, ross 308 strain. poultry by-product meal was prepared from two slaughter house in alborz province. samples were sent to laboratory for determination of chemical analysis. the birds received commercial broiler starter...

nutritive value of rumen epithelial scraping (rep) was assessed using in sacco and in vivo procedures. concentrates were so formulated that 0% (a), 35% (b), 70% (c), and 100% (d) of soybean meal (sbm), were replaced (weight for weight) with rep. in a completely randomized design, 16 west african dwarf (wad) goats were randomly allocated to the experimental diets to assess feed intake and digest...

this study was conducted to determine in vitro crude protein degradation (ivdp) parameters and effective crude protein degradability (epd) of various feeds using the modified in vitro gas production (gp) technique. feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. rumen fluid was collected before the morning feeding from four rumen fistulated lam...

this study was conducted to determine the chemical composition and metabolizable energy of poultry by-product meal (pbpm) from two slaughterhouses in iran. samples were analyzed for dry matter, crude protein, ash, ether extract and gross energy. the amounts of calcium, phosphorus, sodium, potassium, magnesium, iron, manganese, copper and zinc were determined. the apparent metabolizable energy (...
