GROWER PRODUCTION PERFORMANCE USE FLOUR COFFEE PULP AS SUBSTITUTION MATERIALS TO A PARTS OF FINE BRAN ON FEED. Various feed ingredients or waste that have not been utilized for example the skin of coffee fruit can be an alternative feed ingredient source of crude fiber see its content in the skin of the fruit coffee is 33.60%. North Sulawesi, especially Bolaang Mogondow, which is a center of coffee plantation, has a plantation area of 4,097.7 ha, with coffee production reaching 2,135.46 tons of raw material which has not been separated between coffee fruit with its leaves and stems. After the separated coffee fruit obtained as much as 1,288.22 tons per year. Coffee fruit is processed to separate between the seeds and skin after separated obtained by the skin of coffee fruit as much as 448,449 tons. The appearance of production by looking at weight gain, the amount of consumption and the efficiency of feed use is part of the requirement to see the production capability of pigs. The study was conducted for 66 days consisting of 52 days of data collection period and 2 weeks preliminary collecting data aims to determine the effect of coffee skin use as a substitute of some fine bran on the production performance of the grower pigs to the finisher. The study used 16 male and female pigs grower period aged 12-16 weeks descent kinds Yorkshire and Landrace. Randomized block design with four levels of treatment that is 0, 25%, 50%, 75% coffee pulp as a partial replacement of fine bran in 4 groups. Differences in body weight is a replication of the study. The result of analysis of variance (ANOVA) showed that the powder of coffee husk as substitute of bran to the weight gain gave real effect (P <0.05), the amount of feed consumption did not give real effect (P> 0.05) Feed gave a real effect. The result is the use of coffee leaf powder as a substitute of some fine bran in grower pigs until finisher can provide good growth and efficient use of good feed.Keywords: Phase grower, finisher, flour coffee skin

UTILIZATION MANURE DEGRADED USING BLACK FLY LARVAE (Hermetia illucens L) SUBSTITUTING FISH MEAL IN RATION ON LOCAL GROWING CHICKENThe objective of this study was to evaluate the performance of local growing chicken fed ration containing manure flour degraded (MFD) by Larva of black fly (Hermetia illucens L). This experiment was carried out using a complete Randomized Design (RAL), consisted of 4 treatments and five replications in each treatment as follows: R0 = Rations with 15% fish meal + 0% MFD, R1 = 10% fish meal + 5% MFD, R2 = 5%Â fish meal + 10% MFD, and R3 = 0% fish meal + 5% MFD. The variables measured were feed consumption, average daily gain and feed efficiency. Statistical analysis was done according to the procedure using analysis of variance. Results obtained in the research showed that treatments did not affected significantly feed consumption, average daily gain and feed efficiency of local grower chicken. Therefore, it can be concluded that MFD can be used as the candidate ingredient replacing fish meal in ration of the local grower chicken.Key words: Manure flour degraded, fish meal, black fly, kampong growing chicken

UTILIZATION OF MANURE DEGRADED BY BLACKFLIES LARVAE (HERMETIA ILLUCENS L) ON THE PERFORMANCE OF LAYING NATIVE CHICKEN. Native chicken is one of the livestocks that have been widely used for source of protein. It has already been maintained everywhere in Indonesia. Native chickens is widely kept for eggs because it contains good nutrients for human beings. One of the source of rations for native chicken is manure flour from the degradation of the blackflies larvae (MHD flour). This feed material contains a good nutritional value for this chicken. In this study the results of the degradation of manure blackflies larvae processed into flour and added into the rations with the aim to know the consumption of rations, egg production and rations conversion of native chicken. 40 native chickens females aged 56 weeks had been used.Baterry system cages of 50x50x75 cm in size was used to kept the native chickes. Placement of chicken in each unit was done randomly. A randomized complete design (RAL) with 4 treatment and 5 replications was used as design methods (Steel and Torrie, 1991). Each replication using native chickens age 56 weeks with the following treatments: R0 = 0% flour MHD: R1 = 5% flour MHD: R2 = 10% flour MHD: R3 = 15% flour MHD. The variable measured is the sum of rations consumption, egg production and rations conversion. The results obtained showed that there was highly significant difference (P < 0.01)between treatmentsandrations consumption, egg production, and there was no significant difference (P > 0.05) between treatmens and rations conversion. It can be concluded that as much as 15% of the MHDcan be used in chicken rations. Keywords: Native Chicken, Black Flies, MHD flour.
