Abstract

ABSTRACT   EFFECT OF UTILIZATION OF VIRGIN COCONUT OIL (VCO) IN THE DIET ON PIG PERFORMANCE. Utilization of fats and oils in pig diets is of great importance due to their high energy value. VCO is obtained by cold press processing of the kernel from the coconut fruit. Utilization of virgin coconut oil (VCO) in the diets on pig performance.  The present study was designed to elaborate the effect of utilization of VCO in the diets on energy and protein digestibility of growing pigs. The experiment was conducted using 20 castrated male pigs aged 1.5 - 2.0 months weighing 12,0±2,0 kg. The data were analyzed according to the linear model procedure for ANOVA appropriate for Randomized Block Design with 5 treatments and 4 replications. Treatments were formulated as follow: R0 = 100% control diet + 0% VCO; R1 = 99.5% control diet + 1.0% VCO; R2 = 98.0% control diet + 2.0% VCO; R3 = 97.0% control diet + 3.0% VCO; and R4 = 96.0% control diet + 4.0% VCO. Parameters measured were: daily feed intake, daily gain, daily water consumption. The results showed that the utilization of VCO up to 4% in the diets had no significant effect (P > 0.05) on daily feed intake, daily gain, daily water consumption of pigs. It can be concluded that the addition of VCO up to 4.0% in the diets has no significant meaning on pig performance.   Key words: Virgin coconut oil (VCO), Performance, Growing pigs

Abstract

Study was conducted to evaluate the effect of feed restriction and source of different crude fiber on carcass weight and commercial pieces of broiler with Cobb strain. Study was using 24 broilers with Cobb Strain. Restriction of 20 percent feed and different sources of crude fiber were applied to broilers at age of 21to 28 days old. Ration was fed ad libitum to broilers until birds reached age of42 days old. . This research was using a Completely Randomized Design (CRD) in Factorial pattern of 2x4 with 3 replications. As a factor A was restricted feeding consisted of without restrictions (A0), and 20 percents restricted ration (A1). A factor B was source of crude fiber consisted of commercial feed (B0), commercial feed with coffee hull meal (B1), commercial feed with rice bran (B2), and commercial feed with coconut pulp (B3). There were treatment combinations including A0B0, A0B1, A0B2, A0B3, A1B0, A1B1, A1B2 and A1B3. The variables measured were percentages of commercial pieces consist of breast, thigh, wing and brisket. The data analyzed used variance analysis. The honestly significance difference test was used to determine which one of treatment was significantly different from each other. The results showed that the combination treatment of feed restriction and source of crude fiber in feed gave a very significant different effect (P <0.05) on carcass weight of broiler with Cobb strain. Sources of fiber crude affected significantly (P<0.05) percentages of thigh, breast, brisket and live weight. Treatment of feed restriction affected significantly (P<0.05) percentage of wing. Restriction of 20 percents with coconut pulp as source of crude fiber produced better commercial carcass of broilers withCobb strain. Keywords: Feed restriction, crude fiber source, broiler commercial pieces, Cobb strain

Abstract

UTILIZATION OF “GEDI LEAF (Abelmoschus Manihot (L) Medik) AS“ADDITIVE” IN DRINKING WATER RELATED TO THE PERFORMANCE OF INDONESIAN SUPER NATIVE CHICKEN. Research was done to evaluate the performance of Indonesian super native chicken treated with “Gedi” leaf (Abelmoschus Manihot (L) Medik) as“Additive” in drinking water. Study was conducted using hundred individuals of the Indonesian super native day old chicken. The juice of “Gedi” leaf (Abelmoschus Manihot (L) Medik) was given as in forms of the four treatments as follows, drinking water without “Gedi” leaf as control (P0), drinking water with 10 ml juice of “Gedi” leaf per liter of drinking water (P1), drinking water with 20 ml juice of “Gedi” leaf per liter of drinking water (P2), and drinking water with 30 ml juice of “Gedi” leaf per liter of drinking water (P3). Treatments were applied to the birds at 6 weeks old by completely randomized design five replications at each treatment. Data were taken during 5 weeks. Feeds were using 73 percents of commercial feed added by 10 percents of corn and 17 percents of rice bran with nutritional composition of crude protein 19.49 percents, crude fiber 4.66 percents, fat 3.63 percents, Calcium 1.02 percents, Phosphorus 0.66 percents and metabolic energy of 2920 kcal/kg, all given ad libitum. Variables measurement were focused on feed consumption, drinking water consumption, average daily gain, and feed conversion. Results showed that drinking water with 30 ml juice of “Gedi” leaf per liter of drinking water (P3) was not significantly different with other treatments for feed and drinking water consumption, except for average daily gain and feed conversion. The treatments of P1 and P2 were not significantly different for average daily gain, but these treatments were higher in average daily gain compared with control (P0). The highest value of feed conversion was obtained at treatment P3 and the lowest value was found at treatment P1. These values indicated that the best feed conversion was treatment P1. Therefore, it can be concluded that juice of “Gedi” leaf can be used as the alternative additive feed in drinking water up to 20 ml juice of “Gedi” leaf per liter of drinking water in term of high average daily gain and feed conversion of Indonesian super native chicken. Key words: Drinking water, “Gedi” leaf, Indonesian super native chicken.
