Evaluation of Different Breeds of Beef Cattle Bull's Capacity in Producing Frozen Sperms

摘要

Frozen semen production level was specified by quality of fresh semen. Different breeds of beef cattle produce various quality of fresh semen. The aim of this study was to determine differences of frozen sperms production competence of various breed of beef in Artificial Insemination (AI) Center of Ungaran. This study was conducted at Artificial Insemination (AI) Center of Ungaran, Semarang, Central Java, Indonesia. Data collecting was done based on recording data of sperm from 2014 to 2015. Sperm quality and frozen sperm production were observed in Simmental bull, Limousine bull, Brahman bull and Ongole bull. 39 bulls were observed that are 18 Simental, 8 Limousin, 8 PO and 5 Brahman. The method was done by sampling data analysis using Analysis of Variant (ANOVA). The study design was used completely randomized design of sperms production and average production of frozen semen variation between breeds. During 2014 the best sperm production is Limousin bull, but the highest total number of frozen semen produced is Brahman bull. There is no significant difference in the average production of frozen semen among the Limousine cattle, Simental and Brahman, but in the Brahman cattle does. Each individual has the ability to produce spermatozoa with resistance in different freezing processes. The conclusion is sperms production and average production of frozen semen varies between breeds and during 2014 to 2015 the best production is Limousin bulls.
