REPRODUCTIVE PERFORMANCE OF BEEF CATTLE IN BINTAUNA DISTRICT OF NORTH BOLAANG MONGONDOW REGENCY. This study was conducted to evaluate the reproduction performance of beef cattle in Bintauna district of North Bolaang Mongondow regency. Reproductive performance was studied to determine the productivity of livestock especially in population increase and availability of meat. This research used samples of farmer as breeder of beef cattle. The selections of village samples were determined purposively by consideration of the villages with the largest population of livestock including the villages of Pimpi, Kopi, and Bintauna. Selection of respondents using random sampling method involved 10 farmers for each selected village, with the total of 30 farmers as respondents. Data of the variables were analyzed using descriptive analysis model. The results showed that the age of puberty animal was 12.03 ± 4.81 months, service per conception was 1.19, conception rate was 73%, pregnancy period was 276 ± 2.53 days, and calving interval was 366 ± 3.21 days. Based on these results, it can be concluded that the reproduction of beef cattle in Bintauna district of North Bolaang Mongondow regency was categorized into good performance.

REPRODUCTIVE PERFORMANCE BEEF CATTLE OF ARTIFICIAL INSEMINATION IN THE DISTRICT OF NORTH TOMBATU AND SUB DISTRICT OF RATAHAN. The porpose of this study to know appearance of reproduction beef cattle artificial insemination in the northern Tombatu District and the Sub District of Ratahan in the Southeast Minahasa Regency. Research the everage valve standard deviation and coefficient of diversity. Based on research results that service preconception 1.25-1.30, conception rate 70-75%, calving interval 366.4-377.55 and length of pregnancy 279.25-281.1 day. It can be colcluded that the reproductive performance of artificial insemination beef cattle in North Tombatu and Ratahan Districts already quite good.

Several studies have shown that pigs are considered as the main reservoir of Japanese encephalitis virus transmission in Indonesia, in addition to having isolated Japanese encephalitis virus in pigs, pigs are also the type of livestock that is most often reported to contain Japanese encephalitis antibodies with a relatively high infection rate. This study aims to determine the spread and magnitude of Japanese encephalitis virus infection in pigs by detecting the presence of Japanese encephalitis antibodies using the Competitive Enzyme Linked Immuno Assay (C-ELISA). By knowing the spread of Japanese encephalitis virus infection in pigs in North Sulawesi Province, it can indirectly be used as an indicator of the possible threat of Japanese encephalitis virus transmission to humans, especially if the location of pig farms is close to residential areas. The results of serological examination using the Competitive ELISA method on 50 samples of porcine serum in 3 districts/cities, 30% of Japanese encephalitis reactors (15 samples were positive). The JE reactor in pigs in Minahasa Regency is the highest (43.8%) compared to Tomohon City (29.4%) and South Minahasa Regency (17.6%). The proximity of pigs to humans can be seen from the location of the settlements adjacent to the location of pig farms. Pigs located in Minahasa Regency which are close to settlements are the highest risk factors for the transmission of the Japanese Encephalitis virus.
Weight gain, feed consumption and the efficiency of growing pigs to slaughter with palm sugar in drinking water. The production performances by looking at weight gain, consumption and feed efficiency is part of the requirements to see pig production capabilities. The study lasted 10 weeks consisting of 8-week data collection period and 2 weeks of data collecting preliminary aims to determine the effect of the use of palm sugar in the drinking water to the performances of grower to finisher productivities of pigs. The study used 16 mix male and female pigs period grower 12-14 week-old offspring of type cross-bred Yorkshire and Landrace. The experimental design used in this research was Block Randomized Experimental Design with four levels of treatment as follows 0, 2%, 4%, 6% palm sugar in drinking water in four different weight groups as replication. The analysis of variance (ANOVA) showed that the use of palm sugar in drinking water on weight gain (0,57- 0,65 kg) significantly effect (P <0.05), while the amount of consumption (2,56- 2,64 kg) and feed efficiency (0,22-0,25) were not significantly different (P> 0.05), however the amount of water consumption drink (6,57-8,91 litre) indicates the effect of significantly (P <0.05). The use of palm sugar in drinking water in pigs grower phase until finisher can deliver good growth despite the amount of consumption and the efficiency of feed use remains the same.

REPRODUCTIVE PERFORMANCE OF LOCAL BEEF COWS IN BOLAANG DISTRICT OF BOLAANG MONGONDOW REGENCY. This study aims to determine the reproductive performance of local beef cattle in Bolaang District, BolaangMongondow Regency. This study used local beef cattle owned by breeders who were taken as samples in several villages in Bolaang District, Bolaang Mongondow Regency. This study used a survey method to obtain primary and secondary data collection. Data analysis regarding the studied variables used descriptive analysis referring to the measurement of each variable. The results showed that service per conception was 1.38, conception rate was 70%, pregnancy period was 276.47 days, animal age of first calving was 32.022 months, and calving interval was 375.26 days. Based on these results of study, it can be concluded that the reproductive performance of local beef cattle in Bolaang district, Bolaang Mongondow regency was categorized into normal reproductive performance of local beef cattle. Key word: Reproduction, Local beef cow, Bolaang district,
