Feed costs are a major economic expense in finishing and developing cattle; however, collection of feed intake data is costly. Examining relationships among measures of growth and intake, including breed differences, could facilitate selection for efficient cattle. Objectives of this study were to estimate genetic parameters for growth and intake traits and compare indices for feed efficiency t...
Abstract It is essential to know the process efficiency in industrial magnetic separation under different operating conditions because it required control parameters optimize efficiency. To our knowledge, there no information about using artificial intelligence for modeling process. Hence, finding a robust and more accurate estimation method predicting selectivity index still necessary. In this...
. light is an environmental factor, which has profound influences on broilers performance and frequently overlooked management practices. this study was conducted to compare the effects of different lighting programs on growth, carcass parts and economical performance using 320 one day–old broilers (arian 386) in completely randomized design with 4 treatments and 8 replicates per each treatment...

The aim of this study was to examine the effect of Lactic acid bacteria based probiotic and its use schedule on Kurd male calves’ growth performance and white blood cell antimicrobial activity. The experimental period was 105 days after calves adapted to new environmental conditions. This study was carried out by 12 calves with an average body weight of 195 ± 10 kg and age of 240±10 days in a c...
The objective of this experiment was to replace soya bean oil with glycerol in laying hen diets and assess the change's effect on performance, parameters of egg quality and the egg fatty acid profile. A total of 60 44-week-old Hy-Line W36 laying hens were distributed according to a completely randomised experimental design into four treatments consisting of glycerol substitutions for soya bean ...
This study was conducted to investigate the effects of garlic powder on the performance, egg traits, egg cholesterol and serum parameters of laying Japanese quails. One hundred and twenty 10-weeks-old quails were allocated to four dietary treatments. Quails were caged individually and fed diets supplemented with 0 (control), 1, 2, 4% garlic powder for 12 weeks. There were significant (P < 0.05)...
Fish wastes management has become a global problem from the last years. Dispose of seafood wastes cause environmental pollution. To overcome this issue these unwanted seafood products are used for the formation of animal feed and aquaculture feed. These unwanted products include small fish and those parts of fish which are not used as human food. These unwanted parts include viscera, head, fins...
This study was conducted to evaluate fungus, Aspergillus niger, as probiotics in broiler chickens. The Chickens were divided into 4 treatments with average weight (375± 4 g). First treatment as control fed control diet and other chicks were fed diets supplemented with Aspergillus niger at the levels of 0.01, 0.05 and 0.1%. The birds were fed experimental diets until 27 d of age to evaluate the ...
