Judul: Strategi Pengembangan Sapi Bali (Bos javanicus) pada Sistem Pemeliharaan Ekstensif dan Semi Intensif Desa Tawali Kecamatan Wera Kabupaten Bima Nusa Tenggara Barat
Abstrak: West Nusa Tenggara has a program called “Bumi Sejuta Sapi” (NTB BSS). The highest population cattle in NTB was bali cattle. Tawali village in NTB was one of village which developed bali cattle in two farming system. Farming system in Tawali village were extensive and semi intensive. The aims of this study arranged development strategy of bali cattle in two diferrent farming system. Primary data obtained from 42 farmers who farmed with extensive farming systems and 16 farmers who farmed in semi intensive. Secondary data obtained from the village government and related agencies. The Strategies formula of development bali cattle with extensive farming system is purchase breed of bali cattle from the government and the private sector, making hay, using moor for the cultivation of forage with good quality and forming groups of farmers. The strategies formula of development bali cattle with semi intensive farming system is making a warehouse for food storage, organize training about recording of reproduction animal and recording about animal health with cooperation with the government, cooperation between members of the group to supply forage and meet regularly to exchange information between members of the group

Judul: Produktivitas, Potensi dan Prospek Pengembangan Sapi Bali (Bos javanicus) di Desa Pa’rappunganta Kabupaten Takalar Sulawesi Selatan
Abstrak: Bali cattle is one of Indonesia indigenous cattle with high adaptivity of environment and feed. The aims of this study was to determine the productivity, potency, and development prospect of bali cattle in Pa'rappunganta village. This research was conducted from July to August 2011 in Pa’rappunganta village, Takalar region, South Sulawesi. Primary data was obtained through interviewed of 42 farmers. Secondary data was obtained from the village government and related agencies. Data of village profile, farming management and resources were analyzed descriptively. This study also analyzed reproductive characteristic, SWOT (strengths, weaknesses, opportunities and threats) and Increasement Population Capacity of Ruminant (IPCR). The results showed that the age of first oestrus in female bali cattle average was 2,1 years and age of first mating was 2,2 years. Service per conception (S/C) was on average 1,9 times and calving rate mean was 98,1%. Oestrus postpartum of bali cattle in this study was an average of 81.95 days, calving interval was 370±36 days and calf mortality was 5,8%. Result of IPCR analysis showed that capacity of ruminant increase was 137,97 Animal Unit. The result indicated that bali cattle still potential to be developed in Pa’rappunganta village. Result of SWOT analyzed and IPCR showed that bali cattle had a good prospect to be developed in Pa’rappunganta village.
