Abstract

The objective of this study was to evaluate leaf quality of Gliricidia sepium (Jacq) Steud and vegetative growth under different population density and cutting interval in coconut plantation. Plant material of 30 cm length with diameter of 2-3 cm were planted in the poly-bag of 15 x 25 cm size. The area were fertilized using Triple Super Phosphate (TSP) and Kalium Cloride (KCl) fertilizer at 75 kg/ha during land  plough and using N fertilizer (Urea) at 100 kg/ha applied at two months age of plant. Treatment of population density of Gliricidia sepium (Jacq) Steud at 20, 30 and 40 plants per area of 9 m2 combined with cutting interval of 3; 6; 9 and 12 weeks were conducted in this study. Treatments were set in factorial arrangement based on block randomized design. Variables measured were including quality of leaf, dried matter production rate and vegetative growth. Results showed that nutrient content of the leaf of Gliricidia sepium (Jacq) Steud dictated by cutting interval, and vegetative performance influenced by the interaction of population density and cutting interval. In conclusion, to sustain high dry matter leaf production and quality of Gliricidia sepium (Jacq) Steud underneath coconut plantation management should be focused on the planting and defoliation regimes.

Abstract

EVALUATION OF BIOLOGICAL VALUE OF COMPLETE FEED BASED ON CORN COB AND MIXED GRASS ON PRODUCTION PERFORMANCE OF ONGOLE. This study was aimed to obtain the feed formula, which is effective on the productivity of beef cattle (PO). This study consisted of two experimental stages, namely: 1). In vitro experiment, and 2). Biological (in vivo) experiment. t-test two sample assuming unequal variance was used as the statistical analysis on both experiments. The treatments of this research consisted of RA feed = 50% concentrate + 50% corn forage and RB feed = 50% concentrate + 50% mixed grass, and it was repeated 10 times. In vitro test was used to measure dry matter and organic matter digestibility and NH3 concentration (NH3). The biological experiment (in vivo) was used 20 PO cattles, 12-18 months of ages, with 120 - 180 kg of body weight to measure feed intake, nutrients digestibility DMD, OMD, Protein and energy digestibility, live weight gain (LWG) and feed conversion (FCR). The results showed DMD and OMD in vitro of RA were 67.88% dan 66.06%, respectively, lower than the DMD and OMD obtained in RB, i.e 71.15% dan 69.08%, respectively. Meanwhile, NH3 of RA was higher than RB, i.e: 3.20 vs 2.50 mM/L. The biological experiment showed the DMD, OMD, CPD, and DE (in vivo) of RA were 77.05%, 78.64%, 82.13%, and 83.48%, respectively, while the results obtained at RB were higher, i.e. 80.15%, 83.44%, 85.55%, and 87.46%, respectively. On the liveweight gain (LWG) of PO cattle, the RA ration produces 0.60 kg per head per day, lower than RB which produces 0.65 kg per head per day. The FCR of both ration was 0.11. It is concluded, complete feed based on forage corn and mixed grass can be used as standard feed for fattening of local beef cattle because it is able to give high nutrient digestibility and good feed conversion value Keywords: Complete feed, in vitro and in vivo digestibility, liveweight gain, feed conversion

Abstract

THE EFFECT OF DIFFERENT FIBER SOURCES IN THE FEED TO DIGESTIBILITY OF CRUDE FIBER AND HEMICELLULOSE IN COBB STRAIN OF BROILERS. This research was carried out with the aim to determine the effect of providing different sources of fiber in feed on the apparent digestibility of crude fiber and hemicellulose in cobb strain of broilers. This study used 20 cobb strain of broilers 35-day-old. The design used was a Completely Randomized Design (CRD) with the treatment of 4 different fiber sources in the feed which was repeated 5 times. The treatments consisted of: R0 (commercial feed),R1 (commercial feed with coffe skin), R2 (commercial feed with rice bran), R3 (commercial feed with coconut pilp). Variables measured were: apparent digestibility of crude fiber and hemicellulose. Apparent-digestibility measurements using the total collection method. Data were analyzed using general linear model (MINITAB version 16), then differences between treatments were tested with Tukey’s simultaneous test. Apparent digestibility of crude fiber feed has a very different (P<0,01) with treatment R2 and R1. The treatment of R2 was not significantly different (P>0,05) from R1. Apparent digestibility test for hemicellulose shows that R3 is the same as  R0, but it is significantly different (P<0,01) with treatment R2 and R1. The treatment od R2 was not significantly different (P>0,05) from the treatment of R1. It was concluded that coconut pilp as a source of fiber in the feed of strain cobb of broilers provides better digestibility of coarse and hemicellulose fibers than coffe huks and coffe branKeywords: Apparent digestion of crude fiber, Apparent digestion of hemicellulose, strain cobb of broiler

Abstract

PHYSICAL AND CHEMICAL CHARACTERISTICS APPRAISAL OF LOCAL AND IMPORTED RACE HORSES FEED IN MINAHASA The present study was conducted to determine the physical characteristics and nutrient content of racehorse diets both local and imported feed used mostly by race horse breeders in Minahasa region. Race horse breeding management in Indonesia fully adopts methods used in developed countries. Race horse breeders in Minahasa have been practicing of using oats as an imported ingredient to replace local feed rice. This is due to the lack of further testing of local feed, so that race horse breeders practice and rely on using imported feed ingredients to feed their horses just before the horse racing.  A survey method was used to collect data, using interviews and direct observations on several race horses breeding farms. Types and amount of feed (forage and concentrates) both local and imported given to race horse were taken about 500gr for samples analysis. Data were statistically analyzed using t-test. The results showed that the nutrient content of imported feed ingredients significantly higher (P <0.05) compared with local feed. Physical characteristics (color, flavour, shape, and texture) of local food (rice) was significantly different (P <0.05) from that of imported feed (oats). It can be concluded that the nutrient content of imports feed is higher than that of local feed, and physical characteristics of oat and rice, different in colour, shape, aroma, and texture, on the other hand, oat and rice have the same physical shape.

Abstract

EFFECT OF REPLACEMENT OF CORN WITH SORGUM Cv. KAWALI IN PELLET RANSUM ON LOCAL RABBIT PERFORM. The purpose of this study was to determine the effect of substitution corn with sorghum in rabbit rations on feed consumption, body weight gain, and ration conversion. The duration of the study was 28 days using 20 local rabbits. The statistical design used in this study was a completely randomized design, with 4 (four) treatment rations and 5 (five) replications. The four experimental rations, namely R0: 45% corn + 0% sorghum, R1: 30% corn + 15% sorghum, R2 15% corn + 30% sorghum, R3 0% corn + 45% sorghum. Variables were measured, viz: feed consumption, body weight gain and ration conversion. The results showed that the average of feed consumption, body weight gain, and feed conversion, were: 28.27–30.59 g /head /day, 15.76–21.55 g / head /day, and 1.42-1.80 g /head /day, respectively. Based on the analysis of variance, the treatments ration had no significant effect (P> 0.05) on consumption, but had a very significant effect (P <0.01) on body weight gain and feed conversion. The LSD test showed that all treatment rations using sorghum (R1, R2, and R3) gave results of body weight gain which were very significantly different (P <0.01) and higher than R0. Whereas, on ration conversion, treatments R1, R2, and R3 give very different results (P <0.01) lower than R0. It is concluded that the substitution of corn with sorghum at the level of 45% in the ration gives the highest results for body weight gain and conversion of rations for rabbits. Keywords: corn, sorghum, ration, performance, local rabbit
