Abstract

The effects of different lighting regimes on the oviposition schedule, productive performance, and reproductive efficiency in cage housed laying hens of layer parental flock (Hisex White-R) were studied; the reasonable regime of artificial insemination (AI) under intermittent lighting is proposed....

Abstract

Strategies that would increase eggshell quality could be of considerable value to egg producers. This research demonstrated the effective use of fibroblast growth factor 23 (FGF-23) peptide vaccines to increase eggshell quality of Single Comb White Leghorn laying hens (from 69 to 72 wk of age)....

Abstract

Probable involvement of avidin and avidin-related protein-2 (AVR2) in sperm viability in the sperm storage tubules of turkeys has been suggested. The high affinity of biotin to avidin and its analogs is also well documented. The present study aimed to determine the effect of oral biotin on...

Abstract

A total of 160 Inshas and Gimmizah laying hens, 35 weeks of age, was divided into eight groups of 20 hens each. Groups 1 and 3 were inseminated once a week, while groups 2 and 4 were inseminated twice a week. The depth of intravaginal insemination was 3 cm in groups 1 and 2 and 5 cm in groups 3 and ...
