Boar semen is usually collected by the gloved hand method, allowing possibilities for bacterial contamination during the collection process as well as during the subsequent processing of the semen. Bacteria such as Staphylococcus and Streptococcus spp., are found on the skin and mucosa of health animals as well as in the gut (e.g. enteric bacteria) and respiratory tract [1]. Personnel also repr...

Artificial insemination (AI) of swine is widely practiced in countries with an intensive pig production. It is a very useful tool to introduce superior genes into sow herds, with minimal risk for disease transmission. However, the impact of semen that is contaminated with pathogens can be enormous. Most of the micro-organisms that have been detected in boar semen are considered non-pathogenic, ...

OBJECTIVE To probe the toxicity and relative application theory of the commonly-used traditional Chinese herbal drug Taoren (Semen Persicae), and set up a correct attitude and principle and method to use Taoren (Semen Persicae) for treating the syndrome of stagnation of blood stasis and others in TCM clinic. METHODS In this study, we analyzed and probed the ancient and modern literature resea...

OBJECTIVE This study aimed to assess and compare sperm motility, concentration, and morphology recovery rates, before and after processing through sperm washing followed by swim-up or discontinuous density gradient centrifugation in normospermic individuals. METHODS Fifty-eight semen samples were used in double intrauterine insemination procedures; 17 samples (group 1) were prepared with sper...

introduction: to evaluate and compare efficiency of sil-select with percoll to recover sperm with normal chromatin in morphology and also studyeffect of these parameters on fertilization, embryo quality and cleavagescore. materials and methods: assessment of semen parameters, protamine deficiency (cma3) and excessive histone (aniline blue staining) were carried out before and after sperm proces...

Artificial insemination (AI) is an efficient and cost-effective strategy to improve the genetics and reproductive performance of a herd. Reputable commercial AI stud and custom semen collection businesses, through stringent collection, processing and quality control, provide a highly fertile product to their customers. When semen is purchased and transferred to the producer’s liquid nitrogen re...

The equine shipped semen industry has developed and grown during the past few years, especially since the largest horse registry within the U.S., The American Quarter Horse Association, has recently sanctioned its use. However, a tremendous variation exists in the quality of shipped semen. This is due to factors ranging from the inherent ability of the stallion’s semen to withstand a particular...
