APPLICATION OF SCIENCE AND TECHNOLOGY FOR CATTLE BREEDINGÂ GROUP IN TUMALUNTUNG VILLAGEÂ KAUDITAN SUB DISTRICT NORTH MINAHASA. Cattleâ€™s breeding in Indonesia is generally still done traditionally, which the cattle are allowed to feed themselves, while the numbers of grass / forage become less and lower in nutritional value. This will affect on cattle productivity adversely. To overcome this, it is necessary to peform of a grass silage preservation and supplemental feeding using an urea-sugar palm-block (UGB), so the feed remains available all the time and the nutritional value becomes better. Tumaluntung is a village in KauditanSubdistrict of North Minahasa Regency, which produces brown sugar as its main crop. In this village there are several groups of cattle bereeders, among them group Mateluntung I and Mateluntung II.Pre-survey showed that the problems faced by the cattle breeders in this village were lack of knowledge by group members to raise cattle, lack of knowledge to provide qualified Â of forage sustainability, lack of knowledge about making silage and UGB. Therefore, we had done an empowerment Â cattle breeder groups to increase their knowledge, skills and their income. Method was carried out through counselling and training. Members of the group responded well to this application of science and technology, this can be seen from the availability of elephant grass and dwarf grass. Other products produced were silage and UGB.Â Keywords : Group of breeders, cattle, silage, UGBÂ

THE DEVELOPMENT POTENTIAL OF LAYER POULTRY IN WEST HALMAHERA REGENCY.The objective of this study was to analyse the potential and constraints and strategic priority of laying hen development. Respondents were chosen purposively involving farmers, policy makers and related stakeholders. Breeders weregenerally in their productive age with medium education levels, the breeders who were not been trained and the breeders who had no breeding experience. Majority of breeders had the profession as farmers. The ownership status of the farm business belongs to both group and private, and most of them made their livestock business as a sideline to add their income. Management of cultivation wasnot done properly so that the population fluctuated, and productivity was very low. The main strength was business capital support from local government and egg marketing was relatively easy. The main weakness was the lack of information. The main opportunity was the government policy supporting the livestock industry in conducive situation and the biggest threat was the price of feed tending to fluctuate. The alternative strategy achieved were increasing the market share to achieve market leader position through local government policy, improving the quality of human resources through mentoring and assistance to increase productivity, providing livestock production facilities, especially feed in the area by utilizing available local raw materials, and establishing cooperation through partnership between farmers and the private company. Based on QSPM analysis, the priority of strategy chosen was to establish cooperation through partnership between breeder and private sector / Animal Husbandry Company with the highest total TAS value of 5,353.Â Keywords: layerdevelopment strategy, West Halmahera regency potential.

EFFECT OF PARTLY SUBSTITUTION OF BASAL DIET WITH SWEET POTATO VINES (Ipomoea batatas) Â MEAL ON ENERGY AND PROTEIN DIGESTIBILITY OF PIGS. Pork is one of the meat producer animals that can contribute to satisfy animal protein requirements. Sweet potato vines is considered as an agricultural waste product and can be used as feedstuff for pigs. The present Â study was conducted to determine the utilization of sweet potato vinesÂ substituting basal diet on energy and protein digestibility of finisher pigs. Five â€˜Duroc X Spotted Poland Chinaâ€™ castrated male pigs, aged 3.5 to 4.0 months with an initial body weight 50 kg (Â±2.5 kg) were assigned to four treatments as follow: R0 = 100% basal diet + 0% sweet potato vines meal; R1 = 92.5% basal diet + 7.5% sweet potato vines meal; R2 = 85% basal diet + 15% sweet potato vines meal; R3 = 77.5% basal diet + 22.5% sweet potato vines meal; and R4 = 70% basal diet + 30% sweet potato vines meal. Parameters measured were: energy and protein digestibility. Research reasults showed that there is no significant differences Â (P > 0.05) among treatments on energy and protein digestibility of pigs in the present study. This indicated that utilization of sweet potato vines meal up to 30% replacing basal diet did not affect digestible energy and protein of finishing pigs. It can be concluded that substituting basal diet with sweet potato vines meal up to 30% has no negative effect on energy and protein digestibility of finishing pigs.Â Â Keywords: Sweet potato vines, energy digestibility, protein digestibility, pigs
