Abstract

The study aimed to evaluate the reproductive traits in poultry breeder with different weight ranges of two semi-heavy lineages. The experimental method was completely randomized design in factorial arrangement (3×2) with two factors: reproductive methods (artificial insemination and natural mating) ...

Abstract

A total of 970 eggs were collected from matings involving three genotypes of Nigerian local chickens (Normal-feathered, Frizzle-feathered and Naked neck) and one exotic broiler breeder strain (Anak Titan) to evaluate the effect of crossbreeding on fertility, hatchability and embryonic mortality....

Abstract

White Leghorn chickens were selected for 36 generations for high (HAS) or low (LAS) antibody response to SRBC 5 d after an intravenous challenge. The aim of this study was to investigate possible changes in reproductive soundness resulting from that selection. Age and BW at onset of lay (first...

Abstract

In the present study, we investigated the effect of squalene on the reproductive performance in meat-type male chicken. A total of 480 meat-type males, which were 72 weeks old with body weight of 6.0±0.5 kg were assigned randomly and equally to 4 groups in two independental experiments which...

Abstract

Effects of breed and lay number on seminal characteristics as well as fertility and hatchability of eggs collected from caged geese by assigned mating between ganders and dams with artificial insemination were investigated. In trail 1, a total of 56 ganders and 128 dams on the first lay with...

Abstract

Intensive selection based on growth traits in meat-type breeder flocks has resulted in new breeds expressing early sexual precocity but limited persistence of gonad development. This can be in part circumvented by adequate use of specific light regimes. However, these breeds require environmentally ...

Abstract

In a flock comprising Landes and Hungarian White geese, egg fertility was 85.7% to natural mating and 90.9% to artificial insemination combined with natural mating. For the 2 breeds resp., egg hatchability was 77.1 and 64.8%.
