This study was conducted to evaluate the effects of feeding aerobically processed and vacuum-dried food waste-broiler litter and bakery by-product mixture to finishing pigs on performance, carcass characteristics, meat quality and taste panel test. A corn-soy diet (Control) was replaced with food waste mixture (FWM) at dietary levels of 25% (25% FWM) and 50% (50% FWM) on a dry matter (DM) basis...
Major objectives of the poultry industry are to increase meat production and to reduce carcass fatness, mainly abdominal fat. Information on growth performance and carcass composition are important for the selection of leaner meat chickens. To enhance our understanding of the genetic architecture underlying the chemical composition of chicken carcasses, an F(2) population developed from a broil...
The effects of hydrochloric and butyric acids supplementation to broiler chicken diets were investigated on performance, apparent protein digestibility, intestinal microbial population, carcass characteristics and intestinal histology. In these experiments, 280 male Ross 308 one-day old chicks were assigned to 7 treatments. Each treatment included 4 replicates of 10 chicks. Data were anal...
this experiment was conducted to evaluate the effects of different levels of dried lemon pulp (dlp) on performance, carcass traits, blood biochemical and immunity parameters of broilers. in this experiment 240 of broilers (ross-308) were used in a completely randomized design with 4 treatments and 3 replicates (with 20 birds in each replicate) from 1 to 42 days. experimental diets included: 1) ...
this experiment was conducted to study the effect of dietary n-3 to n-6 ratio on performance, immune response, blood parameters and fatty acids profile of broiler chickens. a total number of 192 one day old broiler chicks were randomly alloctted into 6 groups. chicks of groups 1, 2, 3, 4, 5 and 6 were fed balanced corn-soybean diets containing n-3 to n-6 ratios of 1:1, 1:3, 1:5, 1:7, 1:9 and 1:...
The objective of the current study was to determine the consequences of using indirect carcass measurements on the genetic response and rate of inbreeding in broiler breeding programs. In the base breeding scheme, selection candidates were evaluated based on direct carcass measurements on relatives. The possibilities of using indirect carcass measurements were investigated in alternative breedi...
A feeding study evaluated whether standard broiler diets prepared with grain derived from Syngenta Seeds NK Brand Bacillus thuringiensis (Bt) Corn hybrids had any adverse effects on male or female broiler chickens. Four kinds of corn grain were used in this study: (1) grain from the Bt-expressing field corn hybrid N7070Bt, (2) grain from the N7070Bt hybrid that had been sprayed with Liberty bra...
An experiment was conducted to evaluate the effects of physical form of feed, probiotic and prebiotic feed supplementation on performance and carcass characteristics of broiler chicks. Two handred sixty four Cobb 500 strain chicks were used at a 2×2×2 factorial arrangement in a completely randomized design, with 24 experimental units (8 treatments with 3 replicates of 11 chickenss per replicate...
The objective of the present study was to determine the best dietary level of L-arginine on the growth performance, carcass traits, and blood parameters of female Ross broiler chickens in the starter and grower periods. In this experiment, 192 day old female Ross broiler chicks were fed with 4 dietary treatments in a completely randomized design, in which each dietary treatment included 4 repli...
the objective of this study was to determine the effect of different levels of chicory root and stem powder (crsp) and butyric acid (ba) combination on the performance, carcass traits, relative weight of internal organs and some blood parameters in broiler chickens. two hundred and forty one-day-old broilers (ross 308) were used in a completely randomized design with four treatments with six re...
