Data were collected over the first 4 generations of a divergent selection experiment for residual feed intake of Large White pigs having ad libitum access to feed. This data set was used to obtain estimates of heritability for residual feed intake and genetic correlations (r(a)) between this trait and growth, carcass, and meat quality traits. Individual feed intake of group-housed animals was m...

To study the effect of herb ginger powder on performance, carcass characteristics and blood parameters of broilers used from 192 broiler chicks (Ross ) in a completely randomized design with 4 treatments and 4 replicates ( each replicate of 12 chicks ). All treatments, including different levels of ginger powder ratios of 0, 0.5, 1, 1.5 percent respectively called T1, 2T, T3 and T4 that were ad...

this study was conducted to investigate the effect of supplementation different levels of pomegranate seed pulp (psp) on performance and blood parameters in laying hens. a total of 96 layers hens (hy-line w-36) at 24 week of age were randomly assigned into 4 treatments including 0 (control), 5, 10 and 15% of psp, with 4 replicates containing 6 layers in each. results showed no significant effec...

an experiment with 240 one-day-old lohman male broilers was conducted to investigate the effects of different levels of palm kernel meal supplemented diet with/without enzyme on performance and lactic acid bacteria population of ceca. birds were distributed in 20 experimental units and data were analyzed in a complete randomized design with 2x2 arrangement plus a control diet.the levels of palm...

Effects of different feeding frequencies on growth performance, preprandial metabolic parameters, and endocrine traits were studied in calves up to 28 d after birth and respective postprandial changes were investigated on d 3 and 7. Calves were fed with a computer-programmed automate that allowed frequent daily intakes (GrA; n = 7) or were fed twice daily by bucket (GrB; n = 7) the same daily a...

Background & Aim:Hypericum perforatum L. is native to Iran. This herb is one of the most important medicinal plants and had many medical effects.This experiment was conducted to investigate the effects of feeding Hypericum perforatum and protexin on performance, carcass characteristics and intestinal morphology Japanese quails. Experimental: ...

Body composition traits have potential use in fish breeding programs as indicator traits for selective improvement of feed efficiency. Moreover, feed companies are increasingly replacing traditional fish meal (FM) based ingredients in feeds for carnivorous farmed fish with plant protein ingredients. Therefore, genetic relationships of composition and feed utilization traits need to be quantifie...

protein and energy are the two major components of feed that influence performance of the growing and fattening lambs. provision of the quality of protein in the lamb’s diet does not only improve the animal performance but also ensures profitable animal production. different vegetable protein sources are used to formulate the rations for growing and fattening lambs. these protein sources differ...
