The Effects of Sperm Number and Insemination Interval on the Fertility and Hatchability of Sentul Hens

Abstract

Sexually mature Indonesian native hens (Sentul hens) were housed singly in laying cages and artificially inseminated with combination of three different levels of diluted pooled semen (50 million sperm/0.05 ml; 100 million sperm/0.1 ml; and 150 million sperm/0.15 ml) and at either of three different intervals (every 3, 6 and 9 days). The results show that the sperm number and Insemination intervals had no significant interaction (P>0.05) on % fertility and hatchability. The best fertility around 90 %; P<0.05 was obtained by inseminating interval 6 days with sperm number 100 million/0.1 ml of diluted semen.
