Abstract

Since early fertility decline is a permanent problem of broiler breeders, the aim of this study was to test the effects of various sex ratios, spiking strategies and additional artificial inseminations (AI) on their breeding efficiency. Six breeder flocks were analysed during the whole reproduction ...

Abstract

The aim of this study was to determine the role of fatty acids for sperm survival in the sperm storage tubules (SSTs) of the hen oviduct. The mucosa tissues of uterovaginal junction (UVJ) of White Leghorn laying hens with or without artificial insemination using semen from Barred Plymouth Rock...

Abstract

Avian sperm are stored in the sperm storage tubules (SSTs) of the hen oviduct for a prolonged period. However, the precise mechanisms by which sperm are kept alive in the SSTs are still not fully understood. The aim of this study was to determine whether exosomes are secreted by SST cells and play...

Abstract

Over a long period, White Leghorn (W.L.), Barred Plymouth Rock (B.P.R.) and crossbred hens were repeatedly inseminated with semen from W.L., B.P.R. and White Cornish (W.C.) ♂♂. Egg fertility declined as the period of artificial breeding increased, particularly with W.C. ♂♂. Sperm agglutinin titre...

Abstract

In 1959, Standard-bred Slate and Broad Breasted Bronze turkeys, and in 1960, the latter plus Broad White were used to test the advantages of "fresh" semen, artificially inseminated within 15-55 mins. of collection, over " stale " semen which had been in the oviduct 10-14 days. Examinations were...

Abstract

White Leghorn and New Hampshire virgin pullets were naturally mated or artificially inseminated for a 3-wk. period. The number of pullets showing blood serum agglutination titres against spermatozoa was greater after mating than before. Birds which had an egg fertility > 90% throughout the year had ...

Abstract

IN the spring of 1948 two silver pheasant hens were inseminated with sperm from a Polish Greenleg cock. Of 27 eggs laid after the inseminations, 2 were broken accidentally. From the remaining 25 eggs, 8 embryos died in the early stages of development, one died on the 6th day, and one on the 10th...
