Selection of Bali Cattle as a Bull in Nusa Penida Island-Bali Based on Its Performance and Breeding Value

Abstract

Selection program applied to improve the animal genetic potential. This program can be carried out based on the performance and breeding values ??of the economic trait of each individual. The research was carried out for 5 month (from May until September 2018). The purpose of this study was to find out the superior Bali bull by determining of chest girth male Bali cattle. This study used purposive random sampling method. The number of male Bali cattle with incisor of I0,I1,I2 used in this study were 147,29,19 heads respectively. Performance test was calculated by formula of BV = h2 ( Pi – P ) (Hardjosubroto, 1994). The results showed that the average of chest girth male Bali Cattle for I0, I1 and I2 were 135,65±16,98cm; 159,57±13,75cm and 166,26±19,94cm respectively. Based on the breeding value, male Bali cattle coded BK030 with I1 and BK101 with I2 were recommended as a superior Bali bulls because of their highest ranking.

Selection of Superior Male and Parent Candidates for Etawa Crossbreed Goats based on Breeding Values and Morphometric Characteristics in Jembrana Regency, Bali Province, Indonesia

“…Code 5 goats can be used as male candidates to improve the genetic quality of the goat population in Jembrana district. Warmadewi et al [6] who found that chest circumference has a closer relationship with body weight compared to body length and shoulder height. Therefore, selection to improve the genetic quality of goats is more effective on chest circumference compared to selection on body length and shoulder height.…”

Morphometric diversity of swamp buffaloes in Indonesia: A meta-analysis

“…Heritability of body length in cattle is around 0.34-0.51 and chest girth is around 0.27 to 0.47 (Kamprasert et al, 2019). Heritability at the withers height of Bali cattle is 0.6 (Warmadewi et al, 2017) (Nuraini et al, 2018). Therefore, the breeding program for Buffalo in Indonesia must prioritize frame size and carcass percentage.…”

“…The most prominent advantage of Bali cattle is high fertility [1,2] ; high reproduction; sufficiently good adaptability to new environments, especially the ability to adapt to low quality feed [18] high percentage of carcass and good quality of meat [14] . Based on these advantages, Bali cattle are very feasible to be improved and developed, both in terms of genetic quality and population [20] . In addition, the government has designated Bali cattle as the main local beef producer to support the beef self-sufficiency program in Indonesia.…”

“…Good genetic quality will not be expressed if it is not supported by an optimal environment/feed. Conversely, if the genetic quality is bad/not good, the optimal environment/feed will not provide maximum performance [20] . The action needed to improve the genetic quality of Bali cows is to select and mate within the Balinese cattle breed, so that the purity of the calves can be maintained.…”

“…This can be seen from the body weight of Bali cattle and size of adult male and female bali cattle have decreased when compared to the results of Djagra [5] . If the decline in genetic quality occurs continuously, and runs for a long time, it is feared that Bali cattle, as one of Indonesia's native germplasm, will be threatened by its existence [20] . Efforts to improve the genetic quality of Bali cattle can be carried out by implementing a selection program and application of artificial insemination technology [13] .…”
