Abstract

BIOCONVERSION OF BANANA PEEL Var. Raja (Musa paradisiaca) WITH Rhizopus oligosporus TO CHANGE OFDRY MATTER CONTENT, ORGANIC MATTER AND CRUDE PROTEIN. This study aims to determine the change of dry matter content, organic matter and crude protein in banana peel var. raja (Musa paradisiaca) fermented with Rhizopus oligosporus. The study was conducted for three weeks, using Completely Randomized Design (RAL) consisting of 9 treatments and each treatment was repeated 3 times. The treatment consisted of P1 (inoculum dose 0.2% and 48 hours fermentation time), P2 (inoculum dose 0.4% and 48 hours fermentation time), P3 (inoculum dose 0.6% and 48 hours fermentation time), P4 (inoculum dose 0.2% fermentation 96 hours), P5 (inoculum dose 0.4% and 96 hours fermentation time), P6 (inoculum dose 0.6% and 96 hours fermentation time), P7 (inoculum dose 0.2% and fermentation time 144 hours), P8 (inoculum dose 0.4% and fermentation time 144 hours) and P9 (inoculum dose 0.6% and fermentation time 144 hours). The results of variance indicated that the treatment of dose inoculum and fermentation time had a significant effect (P <0.05) on dry matter content, organic matter and crude protein. Based on the result of this research, it can be concluded that banana peel var. raja bioconversion (Musa paradisiaca) with Rhizopus oligosporus can increase percentage change of dry matter and crude protein but there is decrease of organic matter content. The use of 0.4% inoculum dosage and 96 hours of fermentation time (P5) could increase the percentage change of dry matter content by 6.55%, decrease the percentage change of organic matter content by 3.97% and increase the percentage change of crude protein content by 60, 91%. Keywords: Bioconversion, Banana Peel var.

Abstract

UTILIZATION OF ENSILAGE KEPOK BANANA PEELS REPLACING PART OF CORN IN THE DIET ON CARCASSES AND VISCERA INDICES OF BROILER. The purpose of the present research was to determine the substitution of corn with ensilage kepok banana peels (Musa paradisiaca formatypica) in the diet on  carcasses and viscera indices of broiler. Trial was arranged using an experimental study. Sixty unsexed Cobb day old Chicks (DOC) were used in a Completely Randomized Design arrangement, with 4 treatments and 5 replications. Treatments were formulated as follow: R0 = 50% yellow corn + 0% ensilage kepok banana peels, R1 = 42,5% yellow corn + 7,5% ensilage kepok banana peels, R2 = 35% yellow corn + 15% ensilage kepok banana peels, R3 = 27,5% yellow corn + 22.5% ensilage kepok banana peels. Parameters measured were: carcass weight (g), abdominal fat (%), liver weight (%), and gizzard weight (%). Research results showed that, the subtitution of yellow corn with ensilage kepok banana peels gave a significant different (P<0,05) effect on carcass weight, abdominal fat percentage, liver weight percentage, and gizzard weight percentage. The higher the ensilage kepok banana peels replacing corn in the diets, the lower the carcass weight and abdominal fat percentage, whereas liver weight percentage and gizzard weight percentage both decreased as the subtitution of ensilage kepok   banana    peels   increased.  Carcass percentage was the only parameter that was not affected (P>0,05) by treatments. It can be concluded that the utilization of ensilage kepok banana peels up to 30% or 15% can still substitute yellow corn in broiler diets.   Keywords : Broiler, Kepok Banana Peels, Carcasses, Viscera

Abstract

APPLICATION OF SCIENCE AND TECHNOLOGY FOR CATTLE BREEDING  GROUP IN TUMALUNTUNG VILLAGE  KAUDITAN SUB DISTRICT NORTH MINAHASA. Cattle’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  of forage sustainability, lack of knowledge about making silage and UGB. Therefore, we had done an empowerment  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. Keywords : Group of breeders, cattle, silage, UGB

This study was done to determine the effect of the lighting length on the performance of quail production at 6-14 weeks old. This research was conducted at the experimental laboratory of Animal Production Department, Faculty of Animal Husbandry Sam Ratulangi University Manado, during the period from January 7, 2017 to March 3, 2017. The ration used was SP-22 commercial feed by PT. Sinta Fredmill. The total of quails used were 80 birds. Birds were maintained in a 60cm x 40cm baterrey system, using 5 watts power light. The variables measured were feed consumption, egg production and peak production, egg weight, and thickness of the egg shell. The design used in this study was a completely randomized design with 4 treatments and 5 replications. Each replication of experiment involved 4 quails with the treatments; R0 = 12 hours of illumination; R1 = 16 hours of illumination; R2 = 20 hours of illumination; R3 = 24 hours of illumination. Feeding and drinking water were prepared ad libitum. The result of the analysis showed that duration of lighting did not affect the averages of feed consumption, egg production, egg weight and egg shell thickness, but peak production could be reached more than 80% at the thirteenth week. Therefore, it can be concluded that the addition of light for female quail production at 6-14 weeks old did not affect feed consumption, peak production, egg weight, and thickness of the egg shell Keywords: Quail, performance production, lighting length illumination

Abstract

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. Keywords: layerdevelopment strategy, West Halmahera regency potential.

Abstract

EFFECT OF PARTLY SUBSTITUTION OF BASAL DIET WITH SWEET POTATO VINES (Ipomoea batatas)  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  study was conducted to determine the utilization of sweet potato vines  substituting basal diet on energy and protein digestibility of finisher pigs. Five ‘Duroc X Spotted Poland China’ castrated male pigs, aged 3.5 to 4.0 months with an initial body weight 50 kg (±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  (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.   Keywords: Sweet potato vines, energy digestibility, protein digestibility, pigs
