Lay cycle lengths in the Canadian egg industry are currently 50-52 weeks (68-70 weeks of
age). In light of increased productivity in commercial laying hens over the last few decades …

This study was to assess the impact of permanent or temporary restricted feeding on laying
hen production traits, physiology, and egg quality. Two hundred and forty individually …

Circadian oscillatory system plays a key role in coordinating the metabolism of most
organisms. Perturbation of genetic effects and misalignment of circadian rhythms result in …

Presently, excessive fat deposition is the main reason to limit the development of duck
industry. In the production, the methods of restricted feeding (RF) were widely used to …

Background and Aim: The primary components of fat and protein in chicken diets are

This study was conducted to investigate the influence of different feed withdrawal (FW) and
ad libitum dietary protocols on the behavioral, physiological, and productive traits in …

This study aimed to determine the effects of dietary energy and body-weight (BW) restriction
on layer pullets' growth, uniformity, and feed efficiency. Two experiments were conducted …

Recent studies showed that apart from photostimulation, metabolic triggers may
independently activate sexual maturation and egg production in chickens. However, the …

This study evaluated the external and internal quality characteristics after various storage
periods (SP) of eggs from different management practices (MP) regarding layer hen housing …
