South African indigenous bucks are raised under extensive conditions and are more likely to reject artificial vagina (AV) due to their limited contact with human beings, as they are less handled. The purpose of the study was to compare goat semen collection techniques used for goats based on semen traits of South African indigenous bucks during the natural breeding season. A total of eight Sout...

The influence of thawing procedures on fertility of semen in .25-ml Continental 3 straws was investigated in a series of eight trials utilizing 1,634 cows. The following pregnancy rates were obtained: Trial 1, 38.6 vs 23.0% (P<.05) for semen thawed in 75 C water/7 sec vs "in the cow"; Trial 2, 29.7 vs 22.2% (P>.10) for semen thawed in 75 C water/7 sec vs "in the cow"; Trial 3, 82.8 vs 61.6% (P<...

Aim: Present investigation was carried out to study the physical characteristics of Kankrej bulls semen by evaluation of various semen parameters from neat semen and at various stages of semen preservation. Materials and Methods: A total of 60 ejaculates, 10 each from 6 mature Kankrej bulls, once in a week for 10 weeks, were collected and analyzed for various semen attributes. Result: The mean ...

The influence of semen on immunity in sexually active women has been scarcely studied. The effect of human semen on production of messenger RNA (mRNA) for the anti-inflammatory TH2-related cytokine, interleukin-10 (IL-10), the 70 kDa heat shock protein (HSP70) and the pro-inflammatory TH1-related cytokine, interferon-gamma (IFN-gamma) was examined. Co-incubation of peripheral blood mononuclear ...

In sexual assault cases, particularly those involving internal child sex trafficking (ICST), victims often hide their semen-stained clothing. This can result in a lag time of several months before the items are laundered and subsequently seized during a criminal investigation. Although it has been demonstrated previously that DNA can be recovered from clothing washed immediately after semen dep...

AIM To 1) compare post-wash and post-thaw parameters of sperm processed with PureSperm density gradient technique and swim-up method; and 2) test the efficacy of two commonly available density gradient media PureSperm and ISolate. METHODS This prospective study used semen specimens from 22 patients. Specimens from nine patients were processed by both PureSperm density gradient and swim-up met...

We collected semen from a male Amur leopard cat using the transrectal electroejaculation method and investigated the semen qualities for about four years. In addition, the influence of the season on the spermatogenic function of the Amur leopard cat was investigated with regard to the semen qualities, testicular volume and serum testosterone level. As a result, we could collect semen with good ...

It is of critical importance to understand the modalities of BLV presence in semen, especially with regard to artificial insemination (AI). Presence of bovine leukemia provirus was demonstrated in fresh and frozen semen samples by researchers. In this study paired blood and semen samples from 45 bulls were assessed for the presence of part of gag gene and antibodies to BLV in blood, semen and c...

The aim of this trial was to investigate the fertility of semen doses that contain sperm from either one, three or six Duroc boars. The trial was conducted on five different farms where sows were randomly assigned to three different groups: Group 1: Sows were inseminated with semen doses containing sperm from one boar. Group 2: Sows were inseminated with semen doses containing sperm from three ...

We have approached the problem of refrigerated storage of epididymal sperm samples from red deer by comparing three options: storing the genital (testicles within the scrotum), diluting the semen in extender or diluting the semen in extender supplemented with an anti-oxidant. Twenty-nine pairs of testes were collected. Spermatozoa from one of each of the pairs were immediately recovered, and di...
