The aim of this study was to evaluate the effect of inclusion of tannic acid on some performance traits and nutrient digestibility in Holstein dairy calves. A total of 20 seven days old Holstein calves were randomly assigned to 4 experimental treatments with 5 calves each. The treatments were as follows: 1) basal diet formulated to meet all nutritional requirement of calves according to NRC (20...

an experiment was conducted to evaluate the efficacy of exogenous enzymes supplementation (es) on performance, carcass traits and some blood parameters of broilers chickens. one hundred and eighty day old chicks with 40 ± 2 g initial body weight in a completely randomized design with 3 treatments and 4 replications were fed experimental diets included, 1) basal diet no enzymes (control), 2) bas...

this study evaluated the effects of artichoke leaf powder on growth performance and physicochemical properties of japanese quailfrozen meat after 3 monthstorage. a total of 240 japanese quail chicks (1 d old) were raised over a 42-d experimental period. the experiment was performed as a completely randomized design with 4 replicates of 15 quails in each, using a 4 × 2 factorial arrangement with...

Abstract—Linear programming has been used widely in practice with noticeable success for formulating optimum livestock diets. Diet formulated by linear programming is based on the assumption of linearity between animal yield and nutrient ingredients included in the diet. To overcome the drawback of linear approximation of objective function for diet formulation, there is a need to look for tech...

An eight week feeding trial was conducted to evaluate the potential of Gliricidia maculata leaf meal as dietary protein source in the diet of Cirrhinus mrigala fingerlings. Four experimental diets were formulated to contain 20%, 30%, 40% and 50% G. maculata leaf meal (Diets 1 – 4) to partially replace other protein ingredients in the C. mrigala diet. The diet containing 0% leaf meal served as t...

a total of 240, one-day-old quail chicks (coturnix coturnix japonica) were used to study the effects of artichoke leaf meal (alm) and vitamin e in diet on growth performance, ileal microbial populations and intestinal morphology in a 42-d trial. this experiment was performed as a completely randomized design with 4 replicates of 15 quails each, using a 4 × 2 factorial arrangement with diet and ...

An experiment was conducted to elucidate the effect of graded levels of vitamin D3 in White Leghorn (WL) layer breeders on egg production, shell quality, hatchability of eggs and juvenile performance of offspring during their late laying period (7288 wk). White Leghorn breeder females were randomly divided into 5 groups of 50 each and were housed in individual California cages in an open-side h...

The objective of this experiment was to test the hypothesis that the reduced carcass fat quality that is often observed in pigs fed diets containing distillers dried grains with solubles (DDGS) may be ameliorated if corn germ, beef tallow, palm kernel oil, or glycerol is added to diets fed during the finishing period. A total of 36 barrows and 36 gilts (initial BW 43.7 ± 2.0 kg) were individual...
