Abstract

The immune response of hens during artificial insemination (AI) and the survival of spermatozoa in the oviduct were determined in a series of studies. It was shown that lymphocytes, CD4+ and CD8+ cells were increased in the utero-vaginal junction (UVJ) tissue of low-fertility hens after repeated AI ...

Abstract

The objective was to determine whether expression of estrogen receptor (ER) mRNA in the utero-vaginal junction (UVJ) of laying hens was altered after repeated artificial insemination (AI). Semi-quantitative RT-PCR was used to determine the expression of mRNA of the two types of receptor, ERα and...

Abstract

The hypothesis was proposed that altered sperm hydrolysis of the germinal disc area of the ovum affects embryonic survival. Genetics and damaged spermatozoa were the 2 factors tested. Both factors affect embryonic livability. The mechanism of sperm selection was proposed to be in the oviduct or at...

Abstract

The goal of this study was to determine the mechanism by which the fertility is decreased by repeated artificial insemination (AI) in laying hens. The structures of sperm storage tubules (SST) and lymphocyte population in the uterovaginal junction (UVJ) of Rhode Island Red hens showing a declined...

Abstract

The aim of this study was to determine the effects of artificial insemination on the localization of antigen-presenting cells expressing MHC (major histocompatibility complex) class II mRNA in chicken oviducts. Laying hens (35-weeks-old) were inseminated with fresh semen or sham-inseminated with...

Abstract

When female fowls were inseminated with spermatozoa mixed with a DNA liposome into the magnum (intramagnal), egg production decreased during the first 2 days, and was equivalent to egg production of females inseminated intravaginally. After intravaginal insemination, egg fertility during the 1st...

Abstract

The physiological mechanisms that regulate and maintain the selection, transport and storage of spermatozoa in the oviducts of the main species of domestic poultry are reviewed. Selected spermatozoa are those residing in sperm storage tubules. The review also covers oviduct structure, sperm...

Abstract

139 layer-type and 145 broiler-type fowls were inseminated at 31 or 59 wk of age with 60 × 106 or 240 × 106 spermatozoa. Fowls were killed 1 and 6 h and 2, 4, 7, 14 and 21 days after insemination and their oviduct was prepared for histology. The percentage of uterovaginal gland (sperm storage...

AbstractFull Text

The study was conducted to identify the best time of manual insemination in the afternoon of solar day using RIR hens. The insemination was done hourly from 1400h to 1800h. It was observed that artificial insemination carried out from 1400h to 1600h exhibited higher fertility rate as compared to...

Abstract

A procedure of intramagnal insemination in fowls which involves anaesthesia and laparotomy is described. Hen-day egg production was adversely affected by this procedure. Hens anaesthetised with a mixture of ketamine and xylazine prior to laparotomy laid 14% fewer eggs (P<0.05) than unoperated controls. The postoperative hen-day egg production of hens anaesthetised with xylazine alone was comparable with that of controls. The use of xylazine alone increased the ease of handling sedated hens, and decreased recovery time. Therefore, xylazine is recommended for anaesthetising hens prior to laparotomy.
