Abstract

In birds, after natural mating or artificial insemination (AI), sperms are transported through cloaca or vagina at the utero-vaginal junction (UVJ) of oviduct. Only 1% of the deposited sperm passes through the selection process in the vagina to reach the UVJ. In the UVJ, sperm enter the tubular...

Abstract

Female birds store sperm in sperm storage tubules (SSTs) in the uterovaginal junction of their reproductive tract for days or weeks (depending on species) before fertilization. Sperm are transported from the SSTs to the infundibulum where fertilization occurs immediately after ovulation of each...

AbstractFull Text

This study was carried out to determine the optimum fertility and fertile period using the number of spermatozoa, oviduct condition and timing of insemination of native rooster spermatozoa. Ninety six commercial Isa brown pullets and nine kampung roosters were used in this study in a 3×2×2...

Abstract

Located at the anterior end of the turkey hen's vagina are numerous discrete tubular invaginations of the surface epithelium, collectively referred to as the sperm storage tubules (SSTs). After mating or artificial insemination, sperm ascend the vagina, enter the SSTs, and over the ensuing days and ...

AbstractFull Text

The aim of this study was to examine whether the secreted fluid from the uterus influences the survival and fertilization capacity of fowl sperm in the hen oviduct. Hens with either regular uterine fluid secretion or irregular uterine fluid secretion were artificially inseminated through the...

Abstract

The objective of this study was to examine whether domestic fowl (Gallus domesticus) sperm undergo maturation in their capacity for survival and fertilization in the male reproductive tract. Sperm collected from the testis, epididymis and the proximal, middle and distal vas deferens were...

Abstract

Glycerol (GLY) and egg yolk (EY) are good cryoprotectants of avian and mammalian sperm, but in birds, they strongly inhibit the eventual fertilization of ova. Using the sperm penetration (SP-holes) assay and fertility trials, the present study investigates (1) the possible mechanism by which this...

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

Using semen exhibiting vigourous motility and diluted twofold, it was found that, as far as fertility during the first 6 days after insemination is concerned, a dose as small as about 25 million spermatozoa per insemination can at times give results which are almost as good as those obtained with...

Abstract

In the 1st of 3 experiments, 3 ova (controls), recovered from the magnum of artificially inseminated $ 9 killed 85 min after oviposition, were cultured in vitro for 24 hr; 2 of the 3 were fertile. In the 2nd experiment, 5 ova (negative controls), recovered from the infundibulum of unmated ♀♀ killed ...
