Abstract

ABSTRACTNITROGEN RETENTION AND METABOLIC ENERGY OF BROILER CHICKEN RATION USING SORGHUM MEAL (Sorghum bicolor (L). moench) AS A SUBSTITUTE FOR CORN. The aims of this study was to determine the value of Nitrogen Rretention (RN) and Nitrogen-Corrected Metabolic Energy (AMEn) rations using sorghum meal as a substitute for corn in broiler chickens. The study was carried out using 20 broiler strain Cobb aged six weeks consisting of six preliminary days and four days of data collection. Completely Randomized Design (CRD) was used which is consisting of five treatments and four replications. The treatments used are: R0 = substitute 100% corn or sorghum 0%, R1 = substitute 25% corn or sorghum 12.5%, R2 = substitute 50% corn or sorghum 25%, R3 = substitute 75% corn or sorghum 37.5%, and R4 = substitute 100% corn orsorghum 50%. The variables observed were the Nitrogen Retention value (RN) and Nitrogen Corrected Metabolic Energy (AMEn). Study showed that RN value of R0 (63.38%), R1 (65.69%), R2 (70.76%), R3 (70.77%), R4 (68.03%) and AMEn R0 (2417 , 14 Kkl / kg), R1 (2331.17 Kkl / kg), R2 (2157.87 Kkl / kg), R3 (2261.17 Kkl / kg) R4 (2290.02 Kkl / kg). he treatment gave no significant effect (P> 0.05) on RN value and AMEn. Based on this study it can be concluded that sorghum flour can replace corn to 100% or use 50% in broiler ration seen from the N retention value (68.03%) and AMEn value (2290.02 Kkl / kg).Keywords :     Broiler chicken, corn, metabolic energy, nitrogen retention, sorghum

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

Abstract

PRODUCTION PERFORMANCE OF GROWING PIGS FED RATION CONTAINING CAKALANG FISH WASTE PRODUCT. The study aims to determine the extent of the effect of using fish waste flour as a partial substitute for concentrates in feed on the appearance of grower phase pig production to finiser. Swines are very potential to be developed in North Sulawesi because they have the attributes and capabilities of fast growth rates, high number of litter size, good ration efficiency, and a high percentage of carcass. Cakalang fish waste is one of the feed ingredients that are potentially used as animal feed ingredients because it is easy to be obtained and its price is relatively cheap.  Cakalang fish waste can be processed into fish meal and can be used for animal feed mixtures including swines, poultry and fishery. This research was carried out on the farm belongs to Mr. Cloudio Lumowa, starting with the pre-trial for the 2 weeks and data collection for the 10 weeks, starting on June 14 to August 26, 2017. Research was using 20 heads of gilt and boar with a range body weight of 53-63kg. The research design used was Randomized Block Design (RCBD) involving 4 treatments and 5 replications at each treatment. The treatments of feeding were including R0 = ration without cakalang fish waste flour, R1 = ration + 2% cakalang fish waste flour, R2 = ration + 4% cakalang fish waste flour, and R3 = ration + 6% cakalang fish waste flour. The results of the research showed that the use of cakalang fish waste flour with a level of 2%, 4%, and 6% had a significant effect (P< 0.05) on swine weight gain and feed effciciency, but did not affect significantly feed consumption. Based on the results of the study and discussion of all variables, it can be concluded that the use of cakalang fish waste flour as a partial replacement of concentrate up to 6% in grower to finisher produced the same ration consumption, a good body weight gain and feed efficiency.Keywords: cakalang fish waste, production, grower
