Immunosuppression has historically cost the poultry industry in increased mortality and in performance factors during rearing. In addition, immunosuppression has had a negative impact on the ability of the poultry industry to process chickens due to associated health problems. Industry strategies for controlling immunosuppression are not consistent between broiler companies. The broiler industr...

To take advantage from genetic improvement of broiler chickens, updates must be made of the nutritional levels that promote maximum protein accretion and minimum fat deposition. The development of growth models is a valuable tool to understand nutrient deposition in poultry. This article presents experimental results and methodologies used to obtain prediction equations for true digestible lysi...

Recent studies have suggested the utilization of maggots as a feed supplement forenhanced broiler performance. Maggots, which are a major dietary source of protein, appear during the biodegradation of chicken droppings using house flies. The objective ofthe present study was to investigate the effect of maggot supplementation on the meat quality and growth performance of broiler chickens. A tot...

This study was conducted to find the effect of methionine and threonine supplementations higher than the NRC recommendation on growth performance and white blood cell differentiation of broiler chickens challenged with infectious bursal disease. A total of 450 day-old male broiler chicks were assigned to nine groups. Chickens were fed by three graded levels of DLmethionine [NRC (M1), 2 times NR...

Two experiments were conducted to evaluate the effects of male broiler breeder feed intake on broiler progeny performance. In experiment 1, a low cumulative nutrition program supplied 29,580 kcal of ME and 1,470 g of CP, whereas a high cumulative nutrition program supplied 33,500 kcal of ME and 1,730 g of CP to photostimulation at 21 wk of age. Two diets (HiDiet and LoDiet) were formulated, and...

An experimental study was carried over a period of 42 days using 160 day-old commercial broiler chicks (Ven Cobb) to study the effect of copper and flavomycin as feed additives on growth performance in broiler chicken. The birds were divided into four groups with four replicates of ten chicks in each replicate. The treatment (T1) was control with standard broiler ration and Cu as CuSO4 at 100 p...

A meta-analysis was conducted (i) to evaluate broiler response to partial or total substitution of corn by sorghum and millet and (ii) to determine the effect of soybean meal replacement by cottonseed meal in broiler diet. The database included 190 treatments from 29 experiments published from 1990 to 2013. Bird responses to an experimental diet were calculated relative to the control (Experime...

Objective: The aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (CGM) and its effect on growth performance of broiler chicks. Methods: Chemical composition and nitrogen corrected true metabolizable energy of CGM was determined by standard and precision-fed cockerel assay methods.  For evaluating of protein quality, 90 male broiler chicks in a com...

459P Effects of early imprinting and replacing inorganic Zn with different levels of Zn proteinate in broiler diets on growth performance and tissue zinc status of broiler chicks. S. Mwangi*1, T.

feed restriction strategies are proven to be effective in increasing the growth performance and carcass parameters of broiler chickens. the objective of the present experiment was to evaluate the effects of feedremoval for three hour time periodon growth performance and carcass parameters of relatively older male broiler chickens. twenty days old male broiler chickens (n=80) were allocated into...
