Abstract

EFFECT OF SUBTITUTION OF BASIC RATIONS WITH PAPAYA LEAF MEAL ON BROILER PERFORMANCE.  This research aims to know the effect of substitution of basic rations with papaya leaf meal on broiler performance. Using 100 broiler chickens aged 2 weeks with an initial weight rate of 278.75 g. The design used was complete random design (CRD) consisting of 4 treatments and 5 replications. The arrangement of the treatment was as follows: R0 = 100% basal ration (RB) + 0% papaya leaf meal (PLM), R1 = 95% basal ration + 5% PLM, R2 = 90% basal ration + 10% PLM, R3 = 85% basal ration + 15% PLM. The results of the analysis of variance showed that the replacement of a portion of basal rations with papaya leaf meal had a significantly different (P < 0.05) on feed intake, daily weight gain and feed conversion. Based on the results of this study, It can be concluded that the using of papaya leaf meal can replace a portion of ration until 5% level.Keywords: Performance, papaya leaf meal, broiler chickens

Abstract

THE DIVERSITY OF QUALITATIVE CHARACTERISTICS IN   NATIVE    CHICKEN  AROUND MINAHASA.  This study aims to determine the diversity of qualitative characteristics in native chicken around Minahasa Regency. A total of 292 adult chickens were used as samples taken randomly and analyzed using descriptive methods. The results showed that the phenotype frequency, color genotype and feather pattern were 0.000515. Trait frequencies of comb shape was 0.000458, cupping color was 0.9957, foot skin color was 0.9949, and spur shape was 0.000193. The degree of heterosigosity of qualitative characteristics of Kampung chickens in Minahasa on average was in the medium category (0.20) to high (0.50). The degree of heterosigosity of the phenotypic traits of native chicken in Minahasa indicated the relative low degree of inbreeding mating. Distribution of phenotypic inheritance of feather color, comb shape and shape of male foot spurs based on samples of native chicken populations were not in genetic equilibrium. The qualitative traits of native chickens in the Minahasa Regency showed a fairly high level of diversity. Key words: native chicken, qualitative characteristics.

Abstract

THE USE OF A COMPLETE FEED BASED ON CORN FORAGE ON  THE DIGESTIBILITY OF CRUDE FIBER AND NITROGEN FREE EXTRACT OF THE FRIES HOLLAND DAIRY  COWS. This study aims to determine of the use of complete feed based on corn forage on the digestibility of crude fiber and nitrogen free-extract (NFE) of the Fries Holland (FH) dairy cows. This research used 14 dairy cows aged 7-8 years with a bodyweight of 300-400 kg. This study used an experimental method with t-test analysis (unequal diversity) consisting of 2 treatments with 7 replications. This study was arranged in two treatment groups according to t-test (assuming unequal varience). They consisted of Ra = 70% corn forage + 30% concentrate and Rb = 35% corn forage + 35% king grass + 30% concentrate. The variables observed were crude fiber consumption, NFE consumption, crude fiber digestibility and NFE digestibility. T Test analysis results showed that the consumption of crude fiber treatment of Ra (2.07 kg/head/day) was not significantly different (P>0.05) with Rb treatment (2.10 kg/head/day) while NFE consumption showed no significant difference (P>0.05) between Ra (3.36 kg/head/day) and Rb (3.46 kg/head/day). The digestibility of crude fiber showed a very significant difference (P<0.01) between Ra (70.31%) and Rb (78.15%) while NFE digestibility showed no significant difference (P>0.05) between Ra (87.97%) and Rb (90.28%). Based on the results of this study it can be concluded that feeding with concentrate of 30%, corn forage of 35% and king grass of 35% has better in increasing digestibility of crude fiber than just consisting of concentrate of 30%  and corn forage of 70% in dairy cows (FH).Keywords: digestibility, crude fiber, NFE, Fries Holland cows

Abstract

DIGESTIBILITY OF CALCIUM AND PHOSPHORUS COMPLETE FEED BASED ON CORN FORAGE IN ONGOLE CROSSBREED COWS. Research was conducted to evaluate digestibility of calcium and phoshorus ongole crossbreed cows based on Corn Forage. Fourteen cows were used in this experiment, one and a half to two years old by weight of one hundred eighty to two hundred and fifty kilograms. this research was using experimental method, the data were analyzed by T test (Unequal Variance Assumed). Consisting of two replications and seven treatments used. The treatment used was : Ra = 50% concentrate+ 50% corn forage, Rb = 50% concentrate+ 25% king grass + 25% corn forage. The variables measured were feed calcium and phosphorus consumption, calcium and phosphorus digestibility. The results of analysis T test showed that intake capacity of calcium significantly affected (P<0.05) between Ra (31.49 gram/animal/day) and Rb (31.02 gram/animal/day) while calcium digestibility of treatment Rb (84.92%) higher significantly than Ra (77.70%). The results of analysis T test showed that intake capacity of phosphorus Rb (31.45 gram/animal/day) significantly affected (P<0.01) than Ra (30.52 gram/animal/day) and phosphorus digestibility Rb (88.39%) significantly affected (P<0.01) than Ra (83.94%). Based on the research result can be concluded that the complete feed consisting of 50% concentrate, 25% king grass (Pennisetum purpupoides) dan 25% corn forage increase digestibility of calcium and phosphorus ongole crossbreed cows.Key Words: Ongole crossbreed cattle, complete feed, digestibility, calcium and phosphorus.

Abstract

UTILIZATION  OF BANANA CORM (Musa paradisiaca L.) IN DIET ON BROILER CHICKENS PERFORMANCE. The research on the utilization of banana (Musa paradisiacaL.) corm in broiler diet aimed to determine its effect on the performance of broilers, namely the feed intake, weight gain, and feed conversion ratio. The birds used were 100 unsexed days old chicks. This study used a Completely Randomized Design (CRD) consisting of 4 treatments and 5 replications. The composition of the treatment as follows: R0 = 55% corn + 0% banana corm meal (BCM), R1 = 50% corn + 5% BCM, R2 = 45% corn + 10% BCM, R3 = 40% corn + 15% BCM. The result showed that the treatment had a significantly different effect on feedintake, body weight, and feed conversion ratio. Based on the results of the study, it was concluded that banana corm can be used up to 10% in broiler chicken diet.

Abstract

ENERGY DIGESTIBILITY AND TOTAL DIGESTIBLE  NUTRIENT IN DAIRY COWS GIVEN COMPLETE FEED BASED ON  CORN FORAGE. The purpose of this research  was to examine the value of energy digestibility and total nutrient digestibility in dairy cows which are given complete feed based on corn forage. 14 head of cattle with age ± 6-8 years weighing 300-400 kg were used in this study. This biological experiment used a statistical analysis of the T test with unequal variations (t-test two sample assuming unequel variance). The treatments consists of: Ra (30% Concentrate + 70% Corn forage), and Rb (30% Concentrate + 35% Corn forage + 35% King Grass). The results showed that the energy intake both of treatments(Ra and Rb) were not significantly different (P <0.05) while the energy digestibility and total digestible nutrient of the Rb treatment were significantly higher (P <0.05) than Ra treatment. It can be concluded that feed treatment using of 30% oncentrate, 35% king grass, and 35% corn forage was obtained the best energy disgestibility and total digestible nutrient values.Keywords: energy digestibility, dairy cows. corn forage , king grass.

Abstract

THE EFFECT OF THE USE OF PAPAYA LEAVES SUBSTITUTED TO BASAL DIET ON THE PERCENTAGE OF CARCASS AND ABDOMINAL FAT PERCENTAGE OF BROILER CHICKEN. This study aims to determine the effect of papaya leaf meal substituted to basal diet on the carcass weight, percentage of carcass, and abdominal fat of broilers. This study used 80 unsexed broilers, day old chick (DOC). The experiment used a completely randomized design (CRD) consisting of 4 treatments and 5 replications. The arrangement of the experimental treatments was as follows: R₀ = 100% basal diet (BD), 0% papaya leaf meal (PLM), R₁ = 95% BD + 5% PLM, R₂ = 90% BD + 10% PLM, R₃ = 85% BD + 15% PLM. The results showed that partial replacement of the basal diet with with papaya leaf meal had no significant effect on carcass weight and the percentage of broiler abdominal fat. The treatment gave a very significant difference on the percentage of carcass. On carcass percentage results showed that R0 was highly significant different from R3 but not significantly different with R2 and R1. Treatment R1 was significantly different from R3 but not significantly different from R2, whereas between treatments R2 and R3 were significantly different. Based on the results of this study it can be stated that the use of papaya leaf meal up to level of 15% can produce a good proportion of carcass and abdominal fat. Keywords: broiler, papaya leaf meal, carcasses, abdominal fat.
