Aspects of semen production in boars

Proceedings of the British Society of Animal Production (1972), 1984
Efficient reproductive performance in the pig breeding herd depends on many different factors including the behaviour and semen production characteristics of the boar. The latter are difficult to measure under on-farm conditions but results are accumulating from experimental and A.I. units (e.g.

Measurement of semen production rates of boars

Australian Veterinary Journal, 1985
Summary: Frequency of semen collection was used to determine methods of stabilising epididymal sperm reserves in young boars in order to measure daily sperm output which then allows estimation of daily sperm production. By collecting from boars 3 times a week (Monday, Wednesday and Friday) most boars reached epididymal stabllisation within 4 weeks and

Factors influencing semen characteristics in boars

Australian Veterinary Journal, 1985
Summary: Factors influencing semen characteristics in young boars reared in a subtropical environment were studied. Age had only a slight effect on semen volume, but had a significant effect on sperm concentration, total sperm in the ejaculate and daily sperm output (DSO), there being marked increase in boars over 12 months of age compared with ...

Assessment of Boar Semen Morphology and Morphometry

The evaluation of sperm morphology is crucial in assessing reproductive health in both humans and animals. In humans, the World Health Organization recognizes the importance of morphology in semen analysis. Similarly, in animal breeding programs, assessing sperm morphology is essential for selecting superior breeding candidates.
