A Bayesian method was developed to handle QTL analyses of multiple experimental data of outbred populations with heterogeneity of variance between sexes for all random effects. The method employed a scaled reduced animal model with random polygenic and QTL allelic effects. A parsimonious model specification was applied by choosing assumptions regarding the covariance structure to limit the numb...

A study was conducted to investigate the effect of chilling method on broiler carcass skin color, moisture retention, breast fillet quality, and functionality. One hundred fifty eviscerated broiler carcasses were removed from a commercial processing line before chilling, transported to the laboratory, weighed, and chilled by dry air or immersion in ice water. Postchill carcasses were weighed fo...

Two commercially available litter treatments, aluminum sulfate and sodium bisulfate, were tested to determine their effect on Campylobacter and Salmonella levels associated with commercial broilers during a 6-wk grow-out period. A total of 20 broiler houses at 10 different locations were studied; 5 aluminum sulfate-treated houses, 5 sodium bisulfate-treated houses, and 10 paired, untreated cont...

An experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (Se) sources on broiler male birds (Ross 308). Uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental Se, negative control), 0.25 ppm of inorganic Se, 0.5 ppm of inorganic Se, 0.25 ppm of inorganic Se + 0.25 ppm of organic ...

this study was designed to investigate the effects of different levels of tarragon powder on performance, carcass characteristics of broiler chickens. two hundred ross 308 male broiler chickens were randomly allocated into four treatments and five replicates per treatment. at each replicate ten birds were used. experimental diets were set on the basis of corn-soy-wheat and ross 308 broiler chic...
