Abstract

Preservation and improvement of production performance Bali cattle as indigenous livestock needs to be done through targeted breeding programs and standards. One of the efforts to improve Bali cattle breeding program at BPT HMT  Serading Sumbawa is to inventory the data size as a measure of body dimensions seeds stud with the right candidate. Dimensions mean are the values that can be measured from the body parts of animals and can be seen on the surface of the cow's body, among others: body height, body length, and chest circumference. Observations obtained in the field (1) The development of Bali cattle population in BPTHMT Serading over the last five years; (2) Distribution of the percentage of livestock deaths; (3) The ratio of male to female animals use; (4) the size of the body of the bulls born in 2013. The size of the body of the male Bali cattle in BPTHMT Serading 1.7-1.9 years of age, still does not meet the minimum requirements of  class III standard ISO: lower chest circumference of 22-30%, 15-26% body length shorter and a shoulder height of 10-17% shorter.

Suggested selection of male Bali cattle in BPTHMT Serading that would be candidates for seed based on the dimensions of the body size, should be performed at least 2 years. Besides bulls, candidates provide the seeds of the descendants of a group that has the ideal sex ratio.
