Studies on the Egg Yolk Agglutinating Factors in Boar Semen
The author and his co-workers have found out that, when the diluents including egg yolk for freezing of boar spermatozoa were used, egg yolk agglutinated immediately after the dilution and most of the spermatozoa were enclosed into the agglutinated masses and their motility was drastically suppressed. On the other hand, by using skim milk-diluent widely used for storing liquid boar semen at 15°...
متن کاملBoar management and semen handling factors affect the quality of boar extended semen
Artificial insemination (AI) is the preferred method for reproduction in the majority of the intensive pig production systems Worldwide. To this end, fresh extended ready-to-use semen doses are either purchased from AI-centres or produced by boars kept on-farm. For profitable semen production, it is necessary to obtain a maximum amount of high quality semen from each boar. This paper reviews cu...
متن کاملStorage of boar semen.
The problems, aspects and methods of liquid storage and freeze-thawing of boar semen are discussed and a review is given on examination of spermatozoa by the recent fluorescent staining methods.
متن کاملEffect of boar semen senility on peroxidation of semen lipids.
T HE livability of stored bull spermatozoa is decreased by aerobic agitation (Prince and Almquist, 1948). Hydrogen peroxide has been implicated in defects of motility, livability and metabolism in spermatozoa of various species (MacLeod, 1943; VanDemark et al., 1949; Tosic and Walton, 1950; Wales et al., 1959). Investigations not involving spermatozoa have demonstrated that exogenous hydrogen p...
متن کاملEvaluating Boar Semen Quality
Determining the initial quality of a boar ejaculate is the first step in semen processing and should ensure that prior to further processing, a high quality artificial insemination dose of semen will be produced. Effective screening methods for ejaculates prior to processing are necessary for improving on farm reproductive performances. Ideally, ejaculates that are thoroughly evaluated prior to...
