some factors affecting crude protein balance (cpb), as a measure of efficiency, were studied using 2824 records of 501 lactating holstein cows. the cpb (kg d-1) was calculated as crude protein (cp) intake (kg) minus cp yield (kg). two different statistical methods including principal components (pcs) and general linear model analyses were used to study the effects of different factors. crude pr...

three groups of 11 new zealand white (nzw) rabbit does, each were reared from 12 weeks of age on iso-energetic diets containing 16, 14 or 12% crude protein (cp) were used to study influences on productive performance, digestibility, some carcass traits, haematological, biochemical and hormonal parameters of rabbit does. the results showed rabbits fed on 16% protein diet had heavier body weights...

Effect of dietary protein lowering and supplementation peppermint extract on yield, carcass, blood parameters microbial population broiler chickens

In this study, effect of different levels of dietary protein (25, 35 and 45 per cent) and water salinity (0-3, 12-15 and 32-35 ppt) on antioxidant enzymes of white leg shrimp (Penaeus vannamei) was studied. 324 P.vannamei (with mean weight±SE: 5.55 ± 0.18 gr) were randomly distributed in twenty seven tanks. Experimental shrimps were fed by formulated diets for 56 days and at the end of the expe...

The relationship between gut microbiota and obesity is well documented in humans animal models. Dietary factors can change the intestinal composition influence development. However, knowledge of how diet, metabolism, interact modulate energy metabolism development still limited. Epidemiological studies show a link consuming dietary proteins fats from specific sources obesity. Animal confirm tha...

Dietary protein quality is commonly defined by the bioavailability of essential amino acids, a function acid composition and digestibility. This review assesses potential for manipulation in organisms, improving nutrition. Animal generally regarded as higher than plant protein, but it also relatively resistant to change. Plant appears more susceptible genetic environmental influence with seed s...

The effect of dietary Terbutaline, a beta adrenergic agonist, on carcass characteristics and blood attributes in 288 Japanese quails was studied from 21 through 49 days of age. Dietary treatments included four levels of Terbutaline [0 (T0), 1 (T1), 3 (T3), and 5 (T5) mg/Kg of the diet]. Quails were bled at the end of the trial for biochemical assays and the carcass characteristics were then mea...

variation in growth, feed utilization and survival was assessed in sturgeon fingerlings of beluga fed different dietary lipid levels. all diets were iso-nitrogenous (protein = 45%) comprising 3.4-3.7 kcal digestible energy g-1. triplicate groups of 35 fingerling beluga with a mean initial wet weight of 2.14 ± 0.07 g (± sd) were fed with four experimental diets containing 6.7, 10.5, 14 and 17% c...

bone mass loss is one of the commonest menopause symptoms, resulting from cessation of estrogen production. compounds which have estrogen – like biological activity similar to “isoflavones” present in plants especially soy, may reduce bone loss in postmenopausal women, because as they are similar in structure to estrogens. this study, therefore, was undertaken to assess the effect of soy protei...
