In this research, influence of Revabio enzyme on improving anti-nutritional of wheat bran (high in fiber, non-starch polysaccharides and phytate) were investigated. The total number of 320 commercial male broiler chicks (Ross 308) in a factorial experiment 4×2 with four replications were used. Treatment consists of four levels of wheat bran (0, 10, 15 and 20 percent) and two levels of enzyme (0...

Using probiotics can control pathogens by a variety of mechanisms. Probiotics can promote growth performance and have, therefore, become increasingly important in the aquaculture industry. Convict Cichlid belongs to the family of Cichlidae and is known for its rapid development in laboratory conditions and is suitable for behavioral examinations. The aim of this study was to evaluate the effect...

In order to study the nutritive value of grades 1 and 2 wheat feed screening and macaroni wastes as energy resources, 360 21-day-old broiler chicks were divided into 36 groups of 10. In this experiment, each experimental levels of feedstuff was used at 0 (control group), 15, 30 and 45%. In addition, their apparent metabolizable energy (AMEn) was determined by Sibbald’s method. Daily feed intake...

A significant challenge facing the world today is the expected 34% increase in the human population by 2050, which will require 70% more food from existing natural and land resources (FAO, 2009). Thus, the efficiency of natural resource use must be improved to meet the food security goals for a growing population while protecting the environment (FAO, 2009). Due to their ability to utilize cell...

The objectives of this study were to estimate (co)variance components for growth and feed efficiency measures, and to compare selection strategies to improve economic efficiency of gain. Variance components for pre- and postweaning growth, body weight, and measures of feed efficiency were estimated from data collected on 1,047 Targhee lambs over 7 yr. Approximately 21 d after weaning, lambs wer...

Background & Aim: Medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.This experiment was conducted to investigate the effects of milk thistle (MT) and thyme seeds (TS) on the performance in broilers. Experimental: In this study, 160 one-day-old (Ross 308) male broiler chicks were divided randomly into four major groups with 4 replicates b...

The present study deals with the isolation and identification of intestinal bacteria from Common carp Cyprinus carpio. and its effect on growth performance. Six experimental feeds such as Fl control (without probiotics), F2 (1ml of Proteus spp.), F3 (2ml of Proteus spp.), F4 (3ml Proteus spp.), F5 (4 ml of Proteus spp.), and F6 (1ml of yeast). Where prepared by using fish meal, Ground nut oil c...

Reaction behaviors and kinetics of catalytic oxidation of toluene with different feed flows over Pt/Zr(x)-HMS catalysts with Si/Zr ratio equal to 5, 10, 20 and 35 were investigated over a wide temperature range (200 – 500 oC). Results show that Pt/Zr(x)-HMS performs more easily toluene oxidation. The kinetic data were fitted by the Power-law and Mars–van Krevelen kinetic models. The fitting res...
