Growth, feed conversion ratio and fillet composition of rainbow trout (initial weight of 9.99±0.109)were investigated in a 6x2 factorial design experiment employing two levels of digestible energy (DE) (2900 and 3500kcal.kg-1) and six feeding rates (1.0%, 2.0%, 3.0%, 4.0%,5.0% of the body weight,(BW) day-1 and to satiation) for 60 days. Specific growth rate (SGR) was highest at 5.0% rati...

Abstract Proteins, inevitable for nutritional security of human beings and legumes, by far, are the cheapest source this vital nutrient. The escalating prices never halting population growth limit per capita availability protein‐rich legumes. In view limited land resource need to grow other food crops, greater protein harvests possible only increasing levels popularly grown context, attempts we...

A feeding trial was performed to evaluate the effects of dietary L-threonine supplementation on growth and body composition fingerlings Rhamdia quelen (initial weight: 4.47 ± 0.39 g). Five diets (370 g/kg crude protein 14.23 MJ / kg digestible energy) containing levels (16.0, 22.0, 28.0, 34.0, 40.0 g threonine/kg protein) were fed quadruplicate groups fishes for 10 weeks. The analysed variables...

At each station, fortified corn-soybean meal diets containing 0, 15, 30 or 45% DDGS were fed to growingfinishing pigs in three phases. A common source of DDGS analyzing 26.3% crude protein, 0.96% lysine, and 9.7% fat was used at each station. Diets were formulated to contain 0.83, 0.70, and 0.58% true ileal digestible lysine during the three phases with diets changed at 133 and 200 lb, respecti...

the objectives of this experiment were to evaluate the effects of dietary protein supplementation in lactating dairy ewe’s diets on milk coagulation properties. milk samples (n=126) were analyzed to assess the source of variation for rennet coagulation ability at the 6th (rca6) and 12th hour (rca12), milk clotting time (mct, s) and an index of milk clotting time (imct, %). in addition, data wer...

BACKGROUND Pea protein (from Pisum sativum) is under consideration as a sustainable, satiety-inducing food ingredient. OBJECTIVE In the current study, pea-protein-induced physiological signals relevant to satiety were characterized in vitro via gastric digestion kinetics and in vivo by monitoring post-meal gastrointestinal hormonal responses in rats. DESIGN Under in vitro simulated gastric ...

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...

Protein available to ruminants is supplied by both microbial and dietary sources. Metabolizable protein (MP) is the true protein which is absorbed by the intestine and supplied by both microbial protein and protein which escapes degradation in the rumen; the protein which is available to the animal for maintenance, growth, fetal growth during gestation, and milk production. Thus, the concept of...
