Growth Performance of Kasila Broiler Parent Stock Reared on Quantitative Feed Restriction under Bangladesh Condition

A total of 201 Kasila broiler parent chicks were reared in an open-sided house from one-day to 22 weeks of age and growth performance and uniformity were monitored. The birds were maintained on quantitative feed restriction and their adaptability was evaluated. The experimental period was divided into three phases, phase I (day-old to 2 weeks), phase II (3 to 8 weeks) and phase III (9 to 22 wee...

Contrast in light intensity, rather than day length, influences the behavior and health of broiler chickens.

Day length and intensity are commonly manipulated aspects of the light environment in commercial broiler production. Both influence circadian rhythms, but it is unclear if they do this independently or synergistically. The effect of light:dark (20L:4D, 16L:8D) and intensity contrasts (1 lx:0.5 lx, 200 lx:0.5 lx) on broiler behavior and health (n=1,004, 4 replicates/treatment) was evaluated. Act...

Duration of fertility in ad libitum and feed-restricted caged broiler breeders.

It has been shown in previous studies that fertility can be reduced in overweight broiler breeder (BB) flocks. In an effort to determine the effect of ad libitum feeding on the duration of fertility in BB hens, 60 52-wk-old Shaver Starbro hens were randomly assigned to one of two treatments, ad libitum feeding (F) or restricted feeding (R) to maintain breeder target weights. All hens were reare...

Profile Analysis and Growth Curve for Body Mass Index of Broiler Chickens Reared Under Different Feed Restrictions in Early Age

The purpose of this study is to investigate the effect of different feed restrictions which were applied in early period on change of Body Mass Index of Ross 308 broiler chickens. For this aim we used to two different statistical methods, namely Profile analysis and Growth curves. The daily body weight and weekly body length change of chickens was collected from 7 days of age to 42 days of age....
