Effect of age at photostimulation on sexual maturation in broiler breeder pullets

Published: June 10, 2021

Summary

INTRODUCTION Genetic selection programs emphasizing broiler growth, breast muscle deposition, and feed efficiency traits over the past 30 yr have led to a rate of change that has not slowed (Havenstein et al., 2003a,b). Photostimulation ( PS ) age, feed allocation, and BW profile of the maturing pullet can all effect nutrient partitioning between growth and ovary development (Robinson et al., ...

Congrats Dr. Renema and Dr. Zuidhof.

Excellent work, a significant contribution toward validating good zootechnical practices. It also serves as a starting point for understanding the processes involved in the onset of lay, grounded in uniformity regarding carcass, fat deposition, secondary sexual characteristics, and body condition, as well as the response to photostimulation—all of which are prerequisites for strong production performance and a low incidence of metabolic diseases.

Greetings from the Universidad Nacional de La Plata, Buenos Aires, Argentina.
