The lifetime egg production capacity of laying hens (ie laying persistency) has increased
tremendously in the last 50 years from 220 eggs in 1960 to 500 eggs in 2019. To improve …

The objective of this study was to develop appropriate correction equations for dual energy
X-ray absorptiometry (DXA) for total carcass composition of live meat-and egg-type …

The egg production model (EPM) described here is a mechanistic and stochastic model that
simulates the amino acid and energy requirements of laying hens. It takes into account their …

Understanding the effect of nutrition on pullet growth curves and body composition may help
to design new feeding strategies that influence body composition and (long-term) laying …

Feathers play a critical role in thermoregulation and directly influence poultry production.
Poor feathering adversely affects living appearance and carcass quality, thus reducing …

Objective This study aimed to evaluate the effect of the ad libitum and restricted feeding
regimen on fasting heat production (FHP) and body composition. Methods Twelve Hubbard …

The objective of this study was to evaluate the effect of a novel consensus bacterial 6-
phytase variant (PhyG) on egg productivity, eggshell quality, and body composition of laying …

Two trials were carried out to develop and validate linear regression equations for body
composition prediction using Dual-energy X-ray absorptiometry (DEXA). In Trial 1, 300 …

Simple Summary This study aimed to investigate the impact of three dietary balanced
protein levels on laying hens, during the rearing and laying phases. The performance and …

Simple Summary Considering the dynamism of the price of feed ingredients, there may be
an opportunity to reduce the egg production cost by reducing the nutritional value of the …
