Abstract

THE EFFECT OF DIFFERENCES CONCENTRATION OF NATIVE CHICKEN CLAW GELATIN ON THE PHISYCAL CHARACTERISTICS OF EDIBLE FILM. This study aims to determine the effect of differences concentration on the physical characteristics of edible film from native chicken claw gelatin. This study used a completely randomized design with the treatment of chicken claw gelatin concentration 5%, 10%, 15 and 20%, each treatment repeated four times. The results showed that the differences concentration of native chicken claw gelatin had significantly different effect (P<0.05) on the value of tensile strength, elongation and thickness of edible film. Based on the results of discussion, it can be concluded that the concentration of native chicken claw gelatin from variables with 10% gelatin concentration had good physical characteristics of edible film. Keywords: Native chicken claw, Edible film Gelatin

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

THE EFFECT OF EXTRACTION TEMPERATURE DIFFERENCES ON GEL STRENGTH, VISCOCITY, YIELD AND pH OF PIGSKIN GELATIN. This study aims to determine the influence of differences in extraction temperature on gel strength, viscosity, yield and pH value of pigskin. This study used a Completely Randomized Design (CRD) with an extraction temperature treatment (40℃, 50℃, 60℃ and 70℃), each treatment repeated four times. The results showed that the differences in gelatin extraction temperature of pigskin had a significantly different effect (P <0.05) on gel strength and yield of pigskin gelatin, but had no significant effect (P> 0.05) on viscosity and pH value. Based on the results, it can be concluded that the gelatin from pigskin with an extraction temperature of 70℃ had a optimal physical characteristics.Keywords : Extraction, Gelatin, Pigskin

Abstract

GROWTH RESPONSE OF Brachiaria humidicola cv Tully grass WITH ORGANIC FERTILIZER BOKASHI LAYING CHICKEN. This study aims to determine the growth response i.e stolon length, number of nodes, number of phytomers, and number of tillers of Brachiaria humidicola cv Tully with bokashi organic laying hens fertilizer. The completely randomized design was applied using four treatments and five replications for each treatment. The treatments were assigned level of bokashi. The levels of bokashi that B0 = 0 tons/ha (control), B1 = 2 tons/ha (1.8 kg/plot), B2 = 4 tons/ha (3.6 kg/plot) and B3 = 6 tons/ha (5.4 kg/plot). The variables measured consisted of stolon length, number of nodes, number of phyitomers, number of tillers. The Results of analysis of variance showed that treatment very significantly different (P <0.01) on stolon length, number of phyitomers, number of tillers and significantly different (P <0.05) on the number of nodes. Test of Honest Significance Difference (HSD) showed that B1 (1.8 kg / plot), B2 (3.6 kg / plot), and B3 (5.4 kg / plot) have higher length of stolone, number of phyitomers and number of tillers than B0. B3 and B2 had higher numbers of nodes than B0. It was concluded that the level 1.8 kg/plot organic fertilizer bokashi chicken laying equivalent to 2 tons/ha gave highest B. humidicola cv Tully growth response. Keywords: growth, B. humidicola cv Tully, bokashi laying Chicken

Abstract

CRUDE FIBER AND FAT DIGESTIBILITY OF INDONESIAN YEARLING LOCAL-RACING HORSE FED LOCAL AND IMPORTED CONCENTRATE. The objective of this study was to determine the ability of racing foals to digest feed both local and imported feed. This study was conducted at the Tonsewer Village, Tompaso District for 30 days consisting of preparation and data collection. The data were collected from type and amount of feed consumed by racing foals and the number of feces (head-1 day-1). The animals of 20 individuals at the ages of 13-24 months old were used in this study. The amount of 10 racing foals were fed local feed and the rests of 10 racing foals were fed imported feed. The variables measured were digestibility of crude fat and crude fiber, found as the difference between the feed substances consumed and those excreted in feces and divided by those consumed feed at 100%. The results showed that the average digestibility of crude fat for local feed was 66.16% and imported feed was 75.16%, respectively. The digestibility of local and imported raw fiber feed was 65.53% and 72.16%, respectively. Based on statistical analysis using the t-test showed that the digestibility of crude fiber and fat of imported feed was significantly different (P <0.05) compared to local feed. This might be due to higher content of the crude fat and crude fiber of imported feed than those of local feed.Keywords: Digestibility, fat, crude fiber Racing horses, local feed, imported feed.

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.
