A chick bioassay with chemically defined amino acid (AA) diets was conducted to compare four different AA profiles: the NRC 1994, Feedstuff 2002, Rhone Poulenc Animal Nutrition 1993(RPAN) and Illinois Ideal Chick Protein (IICP) AA profiles. This battery study involved male and female chicks during 7 to 21 days of age. Indispensable AA were rationed to lysine according to requirement ratios pre...

In a completely randomized design (CRD) experiment with 6 treatments and 4 replicates per treatment, the effect of energy and protein dilution during 6-12 days of age was tested in broilers. Rice hull was used for dilution of energy and protein at levels of 0.05 (control), 10, 15, 20, 25 and 30 percent. The metabolizable energy and crude protein content of the experimental diets were 3089, 2780...

We investigated the effects of a wheat-based diet (WBD) supplemented with different levels of zinc on the performance, intestinal viscosity, immune system and lipid peroxidation of broiler chickens. A total of 240 Ross 308 day-old male broiler chicks were weighed and assigned to six dietary treatments with four replicates (floor pens) of ten birds per pen. Dietary treatments consisted of a WBD ...
The study of zinc bioavailability in foods is important because this mineral intake does not meet the recommended doses for some population groups. Also, the presence of dietary factors that reduce zinc absorption contributes to its deficiency. Rice fortified with micronutrients (Ultra Rice®) is a viable alternative for fortification since this cereal is already inserted into the population hab...
the aim of this study was to evaluate the effects of three lighting programs on immune system and performance of broiler chickens. a total of 288 seven day-old male broiler chicks (ross-308) were randomly distributed between three treatments. each group was housed in the separated room with eight pen and 12-birds per pen. the management conditions were similar for all treatments throughout the ...
An experiment was conducted to evaluate the effect of protein and synbiotic levels performance and carcass characteristics of Japanese quail. The experiment was done using 720 day old quail for 42 days in a completely randomized design with 3×3 factorial arrangements with three levels of protein (sufficient protein diet (24%) during whole period, low protein diet (22.08%) during whole period an...
In this study, 360 rainbow trout fingerlings with an average body weight of 10.93 ± 0.2 g were divided into 3 group of BV (8, 12 and 16 μg of bee venom powder) and a control group (commercial diet free of honey bee venom) with three respective replicates. After one week adaptation with experimental conditions, the fish were fed with experimental diets for 60 days. Results showed that final leng...
The effect of dietary protein level and feed restriction on performance, body temperature and hematological values was evaluated, using Ross 308 broiler chicks under heat stress. For this purpose, three dietary treatments were fed to broilers during 21 to 42 days of age. Two treatments consisted of diets with protein levels recommended by NRC, 1994 and 85% of NRC recommendation and were fed ad-...
