While photoperiod has been generally accepted as the primary if not the exclusive cue to
stimulate reproduction in photoperiodic breeders such as the laying hen, current knowledge …

Chicken meat production relies on successful reproduction in broiler breeders. Challenges
with feed restriction and metabolic dysregulation of reproduction in broiler breeders warrant …

ABSTRACT A precision feeding (PF) system was developed to increase broiler breeder
lifetime reproductive performance through improved flock uniformity. The current study …

An experiment was conducted to study the effect of broiler breeder feeding management
practices on pullet performance, BW uniformity, and carcass traits during rearing (to 22 wk of …

The effect of ME intake (MEI) on the reproductive system was evaluated. Ross 308 broiler
breeder pullets (n= 140) were assigned to 2 treatments from 22 to 26 wk of age:(1) Low …

Perching, especially during the night, is an innate behaviour of chickens and the provision of
perches is mandatory for laying hens in multiple countries. We examined whether broiler …

An empirical nonlinear mixed model was derived to describe metabolizable energy (ME)
partitioning in Ross 308 broiler breeder pullets. Its coefficients described ME used for total …

The impact of growth curve (GC) and dietary energy-to-protein ratio on productive
performance of broiler breeder females was investigated from 0 to 60 wk of age. One-day …

This study aimed to evaluate the effect of early growth (EG) and time of maximum pubertal
growth peak (I2) on development, feed efficiency, carcass composition, and sexual …

Adipokines including adiponectin (ADIPO), chemerin (CHEM) and visfatin (VISF) are
involved in metabolism and reproductive functions. These 3 adipokines are present in …
