The present study was performed to determine the effect of resistant starch as a type of prebiotic and phenolic compound extract on performance, hematological and blood parameters of suckling Holstein calf. For this, 54 suckling Holstein calves (27 male and 27 female) were randomly assigned in 9 treatments including: RS1 (8 g resistant starch), RS2 (16 g resistant starch), PE1 (1800 mg phenolic...
A feeding trial was conducted to investigate the efficacy of Pediococcus acidlactici (Bactocell®) or Baccillus cereus (Toyocerin®)-based probiotics on turkey’s performance, carcass yield, blood parameters and intestinal morphology. A total of 240 1- day-old male Nicholas turkey poults were allocated into three dietary groups with four replicates. A corn-soybean-based diet was used as a basal di...
The influence of dietary oxidized oil was studied on laying hen performance, egg quality and blood metabolites. Experiment was conducted on 160 laying hens (Hy-Line W-36, 54-61 wk of age) in a completely randomized design with five treatments and four replicated cages containing eight birds per cage. Dietary treatments replaced fresh soybean oil in the control diet (3% fresh soybean oil, 15.25...
in order to evaluate the effects of chlorella on broiler performance and immune system, an experimentwas performed by using 80 ross 308 male broiler chicks. the experiment was accomplished incompletely randomized design including 5 treatments with 4 replication and 4 observations in eachreplicate. the basal diet was based on corn-soybean meal (control) and without any additives. agraded level o...

This experiment was conducted to determine the effect of different vegetable oil types on broiler performance, carcass characteristics and fatty acid profile of breast and thigh meat. For it, a total number of 300 day-old cobb-500 broiler chickens were housed in floor pens for 42 days in a completely randomized design, consisted of 5 treatments (soy, flaxseed, canola, corn and sunflower), with ...
An experiment was done for studying different levels of Ca & P (with and without Phytaze enzyme) on liver enzymes and blood parameters in Arian broiler chickens. Two hundred eighty eight broiler chicken were used in a completely randomized design with 6 treatments and 4 replicates with 12 chickens in each floor pen. Broiler chickens were fed with different levels of Ca and P (with or withou...
Two trials were conducted to test the hypothesis that broilers classified as good rather than poor feed converters (low vs. high feed-to-gain ratios, respectively) would show decreased activity (increased lethargy) and reduced fear of human caretakers. In both trials birds were reared to juvenile selection age when the 192 males with the “best” breast and leg conformation were placed into indiv...
Effects of mating sex ratios on production performance in Indian peafowl were investigated at PunjabWildlife Research Institute, Gatwala Faisalabad. Research was conducted from May through August 2007 toexplore the most productive mating sex ratio. The sex ratios have a significant effect on egg production.Maximum mean eggs (1.63) were produced by the sex ratio 1:2 while maximum egg fertility (...
