Analysis results showed there was no significant difference between body weight (BW) of breed cattle among breeds (P>0,05). Since environment was relatively similar in this study, genetics is therefore suggested to affect size of CG. According to Setiadi et al., CG is also determined by size of skeleton which is affected by genetics, and body condition or environment. Chest girth in cattle was affected by sex, age, and its environment such as fodder provided in maintenance region or height of its region. Small size of CG of subtropical breed cattle (Simbal and Limbal) in this study was caused by lack of ability in adapting cattle to environment. Statistical Analysis showed there was significant difference in wither height (WH) of breeds among males (P0,05), but average of chest girth in crossbreed cattle was higher than Bali cattle, where there is tendency that Bos indicus, specifically Brahbal, has higher average of CG. Average of vital statistic (cm) and body weight (kg) of breed cattles at 18-35 months Productivity of Crossbreed Calves The result of performance analysis between crossbreed calves and some breeds showed in Table 1. N = Total samples Comparison of value of quantitative traits on body length, productivity between offspring of Simental x Bali (Simbal), Limousin x Bali (Limbal), Ongole x Bali (Ongbal) and fellow Bali, was analyzed using GenStat (one-way ANOVA). Measuring percentage of phenotype was done with formula below : Note: A = Qualitative traits.
BADAN PUSAT STATISTIK PAPUA SKIN
Primary and secondary data were obtained such as presence of jawls, predominant skin color, border line of body color and ass, tail color, color of line of body and leg, tail color, black eye circle, lack backline, and presence of horn and its direction, and hump. Parameter of performance analysis that are body length (BL), chest girth (CG), wither height (WH), body weight (BW).
Sample Collection There were five groups observed in this study: first offspring of breeds, cement, age of cattle. Performance formula was used for performance analysis : 2.1. 37 cattle mans were involved and 50 breeds (breeds of Simental x Bali, Limousin x Bali, Ongole x Bali and Bali x Bali.) were used for research sample.
AI center have a program of crossbreeding between Bali cattle and some bulls breeds (Simental, Limousin, Ongole, Brahman and Bali). Materials and Methods Research was done with direct survey method all AI center in Prafi. The study aim is to evaluate the performance of crossbreed calves cattle in Manokwari, west papua, Indonesia. Therefore, evaluating the AI program is necessary to know the successful strategy. So, they use AI program for the solving this problem. This strategy affect to cattle growth and reproduction. Semi-intensive strategy or traditional livestock is used for keeping the cattle in Manokwari. The goverment provide Bali cattle and crossbreeding program using artificial insemination (AI) from several superior breeds such as Simmental, Limousin, Brahman, Ongole and Bali cattle. Local goverment support the program for cattle breeding center in Manokwari. There is tendency of decreased genetic quality of Bali cattle as shown in decreasing of body size. Introduction Manokwari, West Papua, Indonesia develop Bali cattle breeding, But it has some serious problems such as Productivity of Bali cattle are considered low.
