Abstract

There was no significant deterioration in semen characters over the period. Highly significant correlations were found between volume and sperm concentration (0.27) and between sperm motility and sperm concentration (0.31). Overall CR of 55 females inseminated with fresh semen was 83.6%, and CR to...

Abstract

Data covering a 9-yr period were analysed on 46 000 heifers and cows, and on 90 000 ejaculates of 241 bulls, of which 188 were Russian Black Pieds (RBP). Optimum values for some traits were as follows: post-partum insemination interval, 31-60 days; dry period 50-70 days; age at 1st mating, 18-22...
