OBJECTIVE This study evaluated the change and function of the pancreas, and small intestine in relation to growth performance of broilers on diets supplemented with raw soybean meal (RSBM) and protease. Samples of test ingredients and diets, after mixing and prior to being used were also assessed on contents of anti-nutritional factors. METHODS A 3×3 factorial study was used, with three level...

A total of 32 select line (SL) and 32 control line (CL) Duroc pigs were used in two trials to determine the effect of dietary amino acid contents during the grower (G) phase and selection for lean growth efficiency on growth performance, carcass traits, and meat quality. In each trial, pigs weighing 20 kg were assigned to 16 pens with two gilts or two castrated males per pen, and pens were rand...

Background: Selecting the appropriate amino acid levels according to age of modern broiler chicken is critical since proteins are costly. This study, therefore, evaluated performance by modulating growth curve through varying balanced protein (BP) regimen under conventional all step-down phase feeding. Methods: In total, 1750 one-day-old straight run chicks (Hubbard) were randomly allocated 10 ...

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 looked at the effects of processed kola nut husks meal (PKHM) utilization as a feed ingredient on broiler chicken in 42-day feeding trial. Kola pod were into PKHM using ash treatment and rumen liquor fermentation. Three experimental diets developed both starter finisher phases, with included 0, 4, 8%, dubbed 1, 2, 3, respectively. In fully randomized design, 240 Arbor Acres chicks ra...

Breeding leaner pigs during the last decades may have changed pig's empty body (EB) composition, a key trait for elaborating feeding recommendations. This research aimed to provide new experimental data on changes in the chemical composition of the EB of pigs from 20 to 140 kg BW. In addition, the impact of a reduction in the dietary CP associated with lower lysine, methionine+cystine, threonin...

Five experiments were conducted to determine the true ileal digestible Trp (tidTrp) requirement of growing and finishing pigs fed diets (as-fed basis) containing 0.87% (Exp. 3), 0.70% (Exp. 4), 0.61% (Exp. 5), and 0.52% (Exp. 1 and 2) tidLys during the early-grower, late-grower, early-finisher, and late-finisher periods, respectively. Treatments were replicated with three or four replications, ...

Graded levels of a trace mineral premix containing an organic (Bioplex) source of Cu, Fe, Mn, and Zn was evaluated with additional treatments containing organic Zn or Fe. Grower-finisher pigs were fed from 25 to 115 kg BW. The number of pigs in the experiment, the breeding/genetics of the pigs, the management, and the average age of the pigs were previously reported. The experiment was conducte...
