The spermatological properties of semen and results of fertility of frozen Angora Goat semen

Estimated average semen volume in 43 ejaculates of 5 sires was 0.98 cc varying from 0.4 to 2.0 cc. Average motility of the spermatozoa estimated in the fresh semen was 86 % varying between 70 and 90 %. Average spermatozoa concentration of the semen was 3.674 x 10⁶ in 1 cc. Varying between 1.660 x 10⁶ and 5.200 x 10⁶. Estimated abnormal spermatozoa was 2.3 % in average. The abnormal spermatozoa head without tail was in the rate of 0.60 % and turned tail was the rate of 0.40 %.

Egg yolk and natrium citrate diluter that consist 7 % glycerol was used to freeze the Angora Goat semen. The semen that was prepared in 0.25 cc straw which contains about 50 x 10⁶ spermatozoa for one inseminating dose and froze in liqued nitrogen at –196 ºC.

The dissolving motility of the frozen semen at 34 &orm;C just after the freezing and 48 hours later was between 40 and 55 %.
