Effect of season and ejaculate number on the chemical composition of N'Dama bull semen


, : Effect of season and ejaculate number on the chemical composition of N'Dama bull semen. Proceedings, The Fifth World Conference on Animal Production, August 14-19, 1983 Volume 2 Free communication papers: 175-176

Double ejaculates were collected by artificial vagina from eight 3-yr-old N'Dama bulls 4 times weekly during a 9-wk period in each of 3 seasons: dry season (Dec.-Mar.), rainy season (Apr.-July) and late rainy-early dry season (Aug.-Nov.). The concentrations of sodium, potassium, calcium, magnesium, chloride and fructose in whole semen and seminal plasma are tabulated. The chloride concentration was significantly lower in 1st than in 2nd ejaculates.

Achondroplasia (ACH) is the most common genetic form of dwarfism. This disorder is inherited as an autosomal dominant trait, although the majority of cases are sporadic. A gene for ACH was recently localized to 4p16.3 by linkage analyses. The ACH...
