This experiment was conducted to investigate the effects of intensity of restricted early feed and increased nutrient density after restriction period on performance and compensatory growth in broilers. Two hundred and eighty-eight broiler (Lohman) chicks in a completely randomized design in a 2*3 factorial arrangement of treatments were employed. Birds were fully fed from 7 to 13d or 100% of a...

This experiment was conducted to determinate the effects of different levels of Amet protein binder (0, 1.5, 3, 4.5 and 6) in substitution for fish meal on performance and digestibility of nutrients. This study used 400 broiler chickens (Ross strain) with 5 treatments of 4 replications in a completely randomized design. Weight gain, feed consumption, and feed conversion ratio were determined at...

Two experiments were conducted to evaluate the nutritional value of millet and tallow for broiler chickens. In the first experiment, the nitrogen corrected apparent metabolizable energy (AMEn) of millet and tallow were determined by the method of Sibbald. In the second experiment, a 3×5 factorial experiment was designed to evaluate the effects of 3 levels of tallow and 5 levels of substitution ...

the effect of honey, royal jelly and bee pollenon performance, immune system and blood factors of japanese quail, using 160 quail chicks in a completely randomized design by four treatments ]control (without additives), pollen powder 1 g/kg, royal jelly 125 ppm/l, honey 22 g/l) and four replicates of 10 chicks in each replication for 42 days. the experimental groups had no significant effect on...

   This experiment was conducted to investigate the effects of supplementation of different levels of peribiotic of mannan oligosaccharide (MOS) (Celmanax) on performance and some blood parameters of broiler chicks under induced ascites. 320 day-old Ross 308 male chicks were randomly divided into 4 treatments with 4 replicates. The dietary treatments included: positive control (corn – soybean m...

An experiment was conducted to evaluate the effects of high dietary levels of selenium (as sodium selenite) and copper (as copper sulphate) on growth performance, serum biochemical parameters and antibody production against Newcastle disease vaccine (NDV) virus in broiler chickens. A total of 160 Ross 308 unsexed day old broiler chickens were randomly allocated into four treatment groups (n=40 ...

The compensatory growth, proximate composition and amino acid contents changes of young yellow catfish (Pelteobagrus fulvidraco R.) (1.63-1.69 g) had been investigated using a 45-day cyclic feed deprivation and re-feeding experiment. The control group (S0) was fed daily with live tubificid worms (Limnodrilus hoffmeisteri), while the S1/4, S1/2, and S1/1 groups cyclically experienced one-day of ...

Studies were conducted to determine the effects of high dietary ascorbic acid (vitamin C) on growth performance and body composition of a commercially important Asian catfish, Clarias batrachus. During experimental trial in the laboratory condition, the change in growth and feed utilization by the Clarias batrachus fed on three different Vitamin C level have been assessed by the determination o...

The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...
