This study evaluated live performance, carcass, abdominal fat and commercial cuts yields of broilers fed corn-soybean meal diets with increasing digestible valine to lysine levels from 21 to 42 days of age. One thousand five hundred and seventy-five Cobb vs Cobb 500 male broilers were raised with the same commercial mash feed until 21 days of age. Seven treatments with 9 replications of 25 bird...

This thesis evaluates the protein and amino acid requirements of the modern growing-furring blue fox (Alopex lagopus). The effects of dietary protein and the supplemented amino acids, methionine and lysine, on nitrogen (N) retention, nutrient digestibility, growth performance, health, and fur characteristics were estimated in digestibility and N balance trials and production experiments. As wel...

Three experiments were carried out to estimate the optimal ratios of digestible phenylalanine + tyrosine (Phe + Tyr), histidine (His), and leucine (Leu) relative to digestible lysine (Lys) for performance and carcass criteria of Cobb-500 broilers from 8 to 17 d of age. In each experiment, 160 male chicks were allocated to a completely randomized experimental design with eight replicate pens, ea...

results in patients with an svr, the serum levels of aminotransferases were decreased after hcv eradication. although general liver functional tests (albumin and total bilirubin) did not significantly change, the btr values significantly increased. however, in patients without an svr, an improvement in the btr value was not observed after ifn treatment. conclusions hcv eradication can improve t...

using uv-vis spectrophotometric method, the formation constant for interaction of fe2+(aq) ion with l-alaninewas experimentally studied at ph = 4.1 ± 0.01 (50mm of potassium hydrogen phthalate buffer), ionic strengthof 0.1m potassium nitrate and at 5 different temperatures 15,20, 25,30 and 35 t. the optical absorption spectraof mixtures containing considered cation and l-alanine were analyzed b...

Two experiments were conducted to evaluate the nutritional value of three cultivars (Promore, Kiev mutant and Ultra) of white lupins (Lupinus albus L.) for broilers. In experiment 1, the apparent metabolisable energy (AME) and ileal amino acid digestibility coefficients of the three cultivars were determined. The cultivar effects were significant (P < 0.05) for AME, but the ileal amino acid dig...

Sex-separate male and female broilers (2,592 broilers; Ross x 708) were placed in 144 floor pens (12 replications per treatment) and fed diets containing high (H) and moderate (M) amino acid density from 1 to 55 d of age. Diets were formulated using ileal digestible amino acid ratios to Lys. Six dietary treatment combinations (MMMMM, HMMMM, HHMMM, HHHMM, HHHHM, and HHHHH) were implemented in 5 ...

Abstract Three trials were executed to examine the nutritive profile, metabolisable energy and digestible amino acid (AA) contents of four indigenous feed ingredients including wheat (W), middling (WM), canola meal (CM) rapeseed (RSM) in Nile tilapia. samples each test ingredient collected from three different locations Multan (MUL) Sukkar (SKR), Pakistan. The pooled thereafter make a homogenou...
