متن کاملArtificial Insemination and Its Role in Transmission of Swine Viruses
Artificial insemination (AI) in swine is not a new technique and reports as early as the 1930s (Lush, 1925) describe collecting semen for AI. However, because of farm structure changes, increasing farm sizes and separation of production stages, interest in intensive pig production is growing and AI has become a critical component in modern pig production. In 2001, nearly 60% of North American s...
متن کاملDiseases in swine transmitted by artificial insemination: an overview.
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, ...
