Abstract

The objective of this study was to know the incidence of reproductive disorders in smallholder dairy farms. The study was conducted in 12 small dairy farms in Enrekang Regency, Indonesia.  A total of 80 dairy Holstein Friesian cattle consisted of 51 dairy cows and 29 dairy heifers were used in the present study. All dairy cattle at each farm were housed in tie-stall barns.  Reproductive examination was conducted to determine the incidence of reproductive disorders both vaginoscopy and palpation per rectum. The incidence of reproductive disorders was 30.0%; 31.0% in dairy heifers and 29.4% in dairy cows. Uterine infection was the most reproductive disorder suffered to the dairy cattle (12.5%), followed by inactive ovaries and cyst (10% and 5%, respectively). The dairy cattle suffered from reproductive disorders increased the likelihood to mate (artificial insemination; AI) greater than three times as well as to become pregnant. In the population of dairy cattle, 48% AI was conducted greater than three times. The pregnancy rate for the dairy cattle suffered from reproductive disorders was only 20%, with interval from calving to conception was 550 days in average. It can be concluded that high incidence of reproductive disorders in smallholder dairy farms. The occurrence of reproductive disorders decreased the reproductive performance of the dairy cattle in smallholder farms.

Abstract

The research compared the quality of frozen semen (motility, sperm live-cell and spermatozoa abnormality) of Bali Cattle on andromed and tris egg yolk (TKT) diluent. This research used one of the Balinese Bull. Semen was collected five times for two diluent treatments, which was P1= andromed+ aquadest and P2= TKT + glycerol. The parameters measured were motility, sperm live-cell and abnormalities of spermatozoa. Each parameter in each treatment was compared using the T-test (t-test independent sample). This research indicated that P1 was better able to maintain with P2, motility and the percentage of sperm live-cell frozen semen spermatozoa in andromed diluent is still above 40% is 50.8, 6.14% and TKT is 5.03% and a TKT of 33,3 %; 2,64 %. There was no significant difference in abnormalities of frozen semen Bali cows in the two diluents which the respective values for andromed and TKT were 13,2 %; 2,73%; and 14.3 %; 3.51%. It can be concluded that TKT still needs improvement to reach 40% or more.
