Modeling of broiler chicken supply-chain economics depends on robust biological models of growth and yield of broiler chickens. In this paper, 8 dynamic nonlinear broiler carcass and carcass part yield models were evaluated statistically for their suitability for predicting weights of carcass parts. The analysis employed 4 sigmoidal (S) models (Gompertz, modified Gompertz, Richards, and Lopez) ...

The objective of this study was to measure the effect of substituting different levels of shrimp meal (SM) for soybean meal (SBM) in broiler diets. In Experiment 1, 0, 10, 20, 30, and 40% of the crude protein contributed by the SBM in broiler diets was substituted by crude protein from SM. In Experiment 2, 0, 60, 80, and 100% of the crude protein contributed by SBM in broiler diets was replaced...

The effects of selected herbal dietary supplements on the growth performance and carcass quality of broiler chicken were investigated. Three hundred and eight day-old, male broiler chicks of Indian River strain were randomly allotted to seven experimental diets namely negative control, 0.0125% flavomycin (positive control), 0.1% Moringa leaf powder (MLP), 0.05% Moringa leaf powder, 0.035% Zigbi...

Study was carried out to find out the effect of L-carnitine supplementation on carcass characteristics in Venncobb broiler chicks fed with diet containing animal fat. Eighty day old commercial broiler chicks were randomly allotted to two treatment groups (T1 and T2) with four replicates of ten chicks each. The birds were fed with standard broiler chicken ration (BIS, 1992) containing 5% animal ...

Whole carcass rinse is the most common method used to determine Salmonella prevalence in broiler carcasses. However, there is a need to determine the carcass rinse sampling method that best measures the Salmonella status of a broiler carcass as it proceeds through processing, thus allowing the assessment of efficacy of interventions to meet Food Safety Inspection Services (FSIS) performance sta...

The yield of carcass parts as well as levels of carcass fat, moisture, and ash were measured in the 1957 Athens-Canadian Randombred Control (ACRBC) and in the Ross 308 commercial broiler, when fed diets that were representative of those being fed during 1957 and 2001. The Ross 308 was used to represent 2001 commercial broilers. Comparisons of carcass weights of the Ross 308 on the 2001 diet ver...

In the present experiment, 320 one day old Ross 308 broiler chickens were used completely randomized design with 4 treatments, 4 replicates, and each replicate contained 20 broiler chickens. Experimental treatments include control, 0.5, 1, and 2% of Thymolina powder in chickens’ diet. Thymolina is an antibacterial powder drug which is made by composing 4 medicinal plants. A significant differen...

An experimental study in 180 day-old broiler chicks was conducted to evaluate efficacy of herbal liver tonic & growth promoter products on overall growth, performance and carcass quality parameters. Day old chicks were randomly divided into three groups, control group I was given no treatment while group II & III were administered herbal liver tonic & growth promoter products Superliv DS & Xliv...

D6WE (Diet 6 with enzyme); D7NE (Diet 7 with no enzyme); and D8WE (Diet 8 with enzyme). Each of these diets was fed ad – libitum to the experimental broiler finishers. The trial lasted twenty eight days. The feed intake, weight gain, cost per gain (N/Kg) and carcass characteristics were the parameters evaluated. There were significant differences (P < 0.05) in feed intake, weight gain and carca...

Palm Kernel Oil Residue (PKOR) is a waste product obtained after extracting oil from palm kernel by cottage industries. The residue is dumped at processing sites and the stench that emanates from the oxidizing product, causes nuisance to processors and nearby residents. Animal scientists are advocating the use of the fresh product as energy resource in broiler rations. This study was therefore ...
