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 ...

Abstract

Various factors affecting fertility in turkeys, such as initial insemination, semen dose, timing of inseminations and insemination intervals are described. The anatomical and physiological roles of sperm storage tubules, which are located at the urovaginal junction, in maximizing fertility rates in ...

Abstract

The sperm storage tubules (SST) of the turkey hen, which are located in the uterovaginal junction (UVJ) of the oviduct, maintain viable sperm for up to 10 wk after a single insemination. The mechanisms of this in vivo sperm storage are poorly understood. Our objective was to evaluate mRNA and...

Abstract

Egg yolk is one of the most widely used cryoprotective components for sperm preservation and a wide range of factors affect its action on sperm motility, viability and fertilizing ability. The aim of this experiment was to determine the effect of different species egg yolk, namely the domestic...

Abstract

A review. Recent observations in turkeys and fowls show that sperm storage in both species is a highly inefficient process. After AI, <1% of the spermatozoa inseminated are selected for transport to and enter the sperm storage tubules (SST). It has been shown that the sperm selection process is orchestrated within the vagina and not at the level of the SST. At least 2 mechanisms are involved in the selection of spermatozoa fit for sperm storage, one being mechanical (motility) and the other biochemical (sperm-vaginal mucosa interactions). Furthermore, it has been shown that sperm storage efficiency in fowls is dependent upon the logarithm of the number of spermatozoa inseminated. From a practical standpoint, inseminations performed frequently with a moderate number of spermatozoa should be more efficient than inseminations performed with higher doses at longer intervals. ...

Abstract

71 hens were inseminated at the onset of egg production and then once per week. Hens were slaughtered at various intervals, and the UVJ were removed. The percentage of hens with spermatozoa in the lumen of the UVJ was 100, 81, 90 and 53 in hens slaughtered 0-8, 9-36, 37-60 and >60 h after the last ...

Abstract

Of the spermatozoa recovered 24 h after intra-infundibular insemination of turkey hens, about 92% were in the infundibulum and 6% in the magnum. Of the spermatozoa recovered 24 h after intramagnal insemination, about 67% were in the infundibulum, 26% in the magnum, and a total of about 8% in the...

Abstract

The method of semen collection and instruments used are described. Ejaculate volume averaged 0.3 ml. (0.15-0.40) and the av. number of spermatozoa per ml. semen was 7 x 109 (6.5 × 109-7.5 × 109); good quality semen was creamy-white and opaque. Up to 91.15% fertile eggs were obtained when the semen...

Abstract

After biochemical examination of the oviduct and infundibulum and of semen, a diluent was prepared containing inositol, glutamic acid, cysteine, a buffer and glucose. The motility of spermatozoa diluted 1: 3 in it and stored at 15° C remained good for up to 27 hr. Groups of 20 ♀♀ were inseminated...

Abstract

Large-type White turkey hens from a flock with a record of low " fertility " (live embryos at 7-10 days' incubation) were distributed randomly into 4 groups of 50 hens each and were given treatments involving antibiotics and inseminations on a weekly or fortnightly schedule. During the first 5 wks, ...
