Gender selected or sexed semen has been commercially available to the dairy industry for almost a decade. However, sexed semen from beef bulls has only recently become commercially available. The availability of sexed semen from beef bulls along with concerns about success of the technology at the ranch level has limited the use of sexed semen in purebred and commercial beef operations.

The goat polled intersex syndrome (PIS) is a full association between the absence of horns and intersexuality. Several pairs of primer were designed to detect the complete or partial deletion of 11.7 kb fragment in PIS goat. We proved that the 11.7 kb fragment was not deleted completely but partially in PIS goat. The special 198 base substitutions were found between normal and PIS dairy goats, ...

We investigated the polymorphisms of PRLR and FOLR1 genes in Xinong Saanen, Guanzhong, and Boer goat breeds by DNA sequencing and PCR-RFLP. Two novel SNPs were identified: KC109741: g.62130C>T in the 3ꞌ-UTR of goat gene PRLR, and KC136296: g.7884A>C in exon 3 of goat gene FOLR1. In the three goat breeds, the polymorphism information content was 0.20-0.27 at the g.62130C>T locus. At the g.7884A>...

The genetic diversity was studied using microsatellite DNA markers in Laoshan dairy goat (LS), Xinong Saanen dairy goat (SN), Guanzhong dairy goat (GZ), Banjiao goat (BJ) and Guizhou white goat (GW). Within the nine polymorphic loci, allele frequencies, number of effective alleles (Ne), heterozygosity (He), polymorphism information content (PIC), genetic identity (I) and Nei’s standard genetic ...

The effect of gelatin addition to the semen extender on the viability and acrosome integrity of rabbit spermatozoa was studied. Pooled semen samples were processed in a boar semen extender with or without gelatin addition. Semen samples were stored at 5 degrees C for 72 h. Viability and acrosome integrity was evaluated by light microscope. Results showed that gelatin addition had a significant ...

The screening and confirmatory tests available to a forensic laboratory allow evidence to be examined for the presence of bodily fluids. With the majority of evidence being submitted involving sexual assaults, it is important to have confirmatory tests for the identification of semen that are straightforward, quick, and reliable. The purpose of this study was to compare two commonly used semen ...

BACKGROUND Acute lung injury (ALI) is an inflammatory disorder. Semen Cassiae has potent anti-inflammatory activities. The aim of our study was to investigate whether Semen Cassiae plays a protective effect on lipopolysaccharide (LPS)-induced ALI and, if so, to elucidate its potential mechanism. METHODS Male Sprague-Dawley rat lungs were injured by intratracheal instillation of LPS. Rats were...

OBJECTIVE To determine the prevalence of herpes viruses in the semen of an asymptomatic male cohort with and without infertility problems and its association with altered semen parameters. DESIGN A prospective randomized study. SETTING Medical school and IVF clinic. PATIENT(S) One hundred seventy-two male patients undergoing routine semen analysis: 80 with normal semen parameters (control...

Recent advances in reproductive endocrinology and physiology of mammals, molecular biology and genetic engineering have enhanced the expansion of the field of animal reproductive biotechnology. To date, many reproductive techniques have been applied in livestock animals such as cattle, sheep and pigs. Nevertheless, the application of such techniques is still limited in goat. This paper aims to ...
