The effects of dietary lysine, crude protein, energy and feed allocation on broiler breeder hen performance.
This study was conducted to investigate the effects of varying levels of dietary lysine and feed allocation, on the performance of female broiler breeders. In trial 1, 900 Cobb breeders from 26 to 45 weeks of age were ...
The response of broiler breeder hens to dietary lysine : hatchability, embryo growth and subsequent offspring performance.
This study was conducted to determine the effects of breeder hen dietary lysine on offspring performance. In trial 1, Cobb 500 broiler breeder hens were fed 1200, 1070, 930 and 800 mg lysine/bird/d from 26 to 60 weeks of ...
The use of enzyme supplementation for wheat-barley diets in poultry as a means of improving productive performance.
The objective of the study was to evaluate the effect of an exogenous multi-blend enzyme ( -glucanase and xylanase) on the performance of the broiler chickens and laying hens fed diets based on wheat and barley. Experiments ...
The effects of maternal dietary lysine intake on broiler breeder offspring performance.
The aim of this study was to evaluate the effects of broiler maternal dietary lysine intake on progeny performance. Three experiments were conducted with chicks hatched from Cobb 500 breeders at 38, 48, and 60 weeks of ...
Factors influencing breast meat yield in broilers.
The increased demand for breast meat of broiler chickens has challenged researchers to investigate management techniques that could be used to increase the production of this valuable commodity. Two experiments were ...
The productive response of broiler breeder hens to lighting and growth manipulation during rearing.
This study was designed to provide information that would enable the development of a theory to predict age at sexual maturation and settable egg production in broiler breeder hens submitted to a variety of constant or ...

The effect of photoperiod and feeding time on broiler breeder eggshell quality and oviposition time.
This study was conducted to determine the effect of photoperiod and feeding time on oviposition time and eggshell quality of broiler breeders. Five experiments were conducted in total. The effect of photoperiod on ...

The constraining effect of feed bulk on the voluntary feed intake of laying hens.
1. Two experiments were designed to determine a suitable method of measuring and predicting feed bulk, such that this could be used to predict when the feed intake of a laying hen would be constrained by feed bulk. 2. ...
