Influence of thermal stimulation during the late phase of incubation on hatching results and post-hatch broiler performance under commercial conditions

Abstract: Two experiments, which differed in breeder age, strain and season, were conducted to study the influence of low-intensity, short-duration thermal stimuli during the late phase of incubation on hatchability and performance. The first experiment conducted in April-June used eggs from Cobb × Ross broiler breeders at 35-41 weeks of age and the second experiment performed in February-April used eggs from Hubbard × Cobb broiler breeders at 49-53 weeks of age. Eggs in the test group had the same physical environment … Show more

“…They also demonstrated that TM (þ1 8C, 2 h/day from day 18 of incubation until hatching) increased the hatching rate and the weight of hatched chicks, and it resulted in better weight gain up to slaughtering age and a better feed conversion. Elmehdawi et al (2016) reported better feed conversion in broilers as a result of the same thermal manipulation.…”

“…From the six continuous TM studies, the application increased [39], and had no significant effect on hatchability [26,35,36] compared with control groups. Moreover, continuous TM increased [32], decreased [33] and had no significant effect on embryo, chick weight, or chick quality [26,35,39]. Furthermore, Elmehdawi et al [35] reported no negative effect of continuous TM on hatch body temperature compared with control treatment.…”
