to evaluate the effects of supplementation of tomato pomace (tp), canola, soybean and tallow oils on performance, carcass characteristics, and bone parameters of heat stressed broilers, 792 d-old arian broiler were divided to 36 pens. each dietary treatment had 4 replicate with 22 birds each. these factorial experiment (3*3) involved 3 kinds of canola, soybean and tallow oils and 3 levels of 0,...

Feed costs are a major cost component of pig production and the optimal use of feed for production is therefore of high importance in an economic and sustainable pig industry. The amount of food eaten by the growing pig is used for maintenance and growth which includes lean meat as well as fat growth. The aim in pig production is to produce lean meat most efficiently which is achieved by optimi...

this present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg-1 phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. the results of experiment have shown that egg weight was increased by supplementation of 12 g kg-1 feed additive whereas egg production, feed...

Efficiency of beef production is one of those terms that probably means something different to each person discussing the topic. Certainly, efficiency means something different to the packer than to the feeder or cow/calf producer. Beef production practices, and especially breeding, have been largely influenced by feed conversion (one measure of efficiency) in the feedlot and in dressing percen...

the effect of a commercial probiotic (protexin) on growth performance and survival rate in sobaity sparidentex hasta was investigated. 240 fish with average weight of 2.99±0.87g were treated for 10 weeks. this study was carried out in a completely random design with 12 experimental groups, in 4 treatments each with 3 replicates. experimental groups were consisted of four levels of 0.0, 0.5, 1.0...

This case study includes three pig production systems belonging to two companies in Spain. Mortality, percent culls, average daily gain (ADG), and feed efficiency in Production Systems One and Two were incorporated into a database program and analyzed using statistical process control (SPC) techniques to assess changes in performance before and after phytosterols, natural substances that act as...
