Several oilseed and legume protein products were fed to rats as the sole source of dietary protein, and in blends with cereals for the determination of protein efficiency ratio (PER) and biological availability of amino acids. In addition oilseed protein isolates were fed to mice for the determination of PER. Results of the mouse study revealed that the adjusted PER (casein = 100)for Target rap...

Two trials were conducted to study the effect of multi-steps phase-feeding (PF) program on growth performance of broiler chickens from 1 to 24 and 1 to 39 d of age. The control group was the nutrient recommendation of Aviagen (2019) with a three-step PF program (1-10, 11-24 and 25-39 d of age). In the first trial, the control group was compared with an eight-step PF program (PF8), and in the se...

Protein nutritional status indicators were studied in weanling albino Swiss mice infected with S. mansoni and fed the Regional Basic Diet (RBD) from Northeast Brazil, a multideficient diet of low-protein content. Each mouse was infected percutaneously with 80 cercariae. The experiment lasted 63 days. The growth curve, food consumption, protein intake, weight gain, Protein Efficiency Ratio (PER)...

The presented work deals with possibilities in isolating amaranth protein. A biochemical procedure was chosen, consisting in employing enzymes acting specifically on protein degradation. Experiments were executed through two-level factor tests, and the influences under study were those of enzymatic hydrolysis duration (1 and 5 h) and temperature (30 and 50 oC) on efficiency of protein hydrolysi...

a deterministic model was employed to simulate various progeny testing programs compatible with the conditions of holstein dairy cattle population in iran. in simulated programs, the selection intensity of bulls was increased by increasing the ratio of cow population in mate with young bulls. selection accuracy in the programs was fixed because of the fixed progeny group. economic efficiency (t...

breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...

One of the most important targets in Alzheimer disease is Beta site amyloid precursor protein cleaving enzyme-1 (BACE-1). It is a membrane associated protein and is one of the main enzymes responsible for amyloid β (Aβ) production. Up to now, a considerable number of peptidic and non-peptidic inhibitors of BACE-1 have been developed. Recently, small molecule BACE-1 inhibitors have attracted the...

in order to determine the optimal levels of energy and protein in grower diet of japanese quail, 360 dayold japanese quails were used in a 3×3 factorial arrangement of dietary treatments that comprised threelevels of metabolisable energy (2750, 2850, and 2950 kcal/kg) and three levels of crude protein (24, 26and 28 percent) with four replicates per treatment in a completely randomized design. f...
