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 The aim of the study was to evaluate prediction methods, validation approaches and pseudo-phenotypes for the prediction of the genomic breeding values of feed efficiency related traits in Nellore cattle. It used the phenotypic and genotypic information of 4,329 and 3,594 animals, respectively, which were tested for residual feed intake (RFI), dry matter intake (DMI), feed efficiency (FE), feed conversion ratio (FCR), residual body weight gain (RG), and residual intake and body weight gain (RIG). Six prediction methods were used: ssGBLUP, BayesA, BayesB, BayesCπ, BLASSO, and BayesR. Three validation approaches were used: 1) random: where the data was randomly divided into ten subsets and the validation was done in each subset at a time; 2) age: the division into the training (2010 to 2016) and validation population (2017) were based on the year of birth; 3) genetic breeding value (EBV) accuracy: the data was split in the training population being animals with accuracy above 0.45; and validation population those below 0.45. We checked the accuracy and bias of genomic value (GEBV). The results showed that the GEBV accuracy was the highest when the prediction is obtained with ssGBLUP (0.05 to 0.31) (Figure 1). The low heritability obtained, mainly for FE (0.07 ± 0.03) and FCR (0.09 ± 0.03), limited the GEBVs accuracy, which ranged from low to moderate. The regression coefficient estimates were close to 1, and similar between the prediction methods, validation approaches, and pseudo-phenotypes. The cross-validation presented the most accurate predictions ranging from 0.07 to 0.037. The prediction accuracy was higher for phenotype adjusted for fixed effects than for EBV and EBV deregressed (30.0 and 34.3%, respectively). Genomic prediction can provide a reliable estimate of genomic breeding values for RFI, DMI, RG and RGI, as to even say that those traits may have higher genetic gain than FE and FCR.

ABSTRAK. Tujuan penelitian ini untuk mengukur seberapa besar pengaruh minyak ikan yang sudah terenkapsulasi terhadap kolesterol darah dan performa pada Domba. Penelitian telah dilakukan di Sub Unit Pelayanan Pengembangan Pembibitan Ternak Domba dan Kambing (SUPPPTDK) Bunihayu, Subang pada tanggal 20 Januari 2020 sampai 27 Maret 2020. Sebanyak 18 ekor domba Ekor Tipis jantan dengan bobot 15,99±0,98 kg dialokasikan ke dalam 3 perlakuan secara acak. Domba tersebut diberi ransum perlakuan yang disuplementasi dengan mikroenkapsulasi minyak ikan sebanyak 0% (P0), 2,5% (P1), dan 5% (P2). Data yang terkumpul dilakukan analisis ragam dan bila hasil berbeda nyata maka dilanjutkan dengan uji Duncan. Hasil menunjukkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah (P0,05), namun tidak berpengaruh nyata terhadap pertambahan bobot badan, konsumsi dan konversi ransum (P0,05). Penurunan kadar kolesterol terjadi pada kelompok domba dengan perlakuan mikroenkapsulasi sebanyak 2,5% (P1) dan mikroenkapsulasi 5% (P2). Kadar kolesterol darah masing-masing perlakuan berturut-turut adalah 100,70 mg/dl (P0); 96,20 mg/dl (P1); dan 78,76 mg/dl (P2). Rataan yang terbaik pada pertambahan bobot badan, konsumsi bahan kering harian, dan konversi ransum terdapat pada P2 yaitu 63,96 g/hari, 574,13 g/hari, dan 9,08. Hasil penelitian dapat disimpulkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah, dengan penurunan tertinggi pada pemberian 5%.  (The impact of microencapsulation fish oil in feed on blood cholesterols and performance on sheep) ABSTRAK. This study measured the effect of encapsulated fish oil on blood cholesterol and sheep performance. The study was conducted at the Bunihayu Sheep and Goat Breeding Services Bunihayu, Subang on January 20, 2020 to March 27, 2020. A total of 18 male thin-tailed sheep 15.99±0.98 kg were allocated randomly into 3 treatments. The sheep were given feed supplemented with fish oil microencapsulation of 0% (P0), 2.5% (P1), and 5% (P2). The data were collected and analyzed by analysis of variance and, if the result is significantly different, continued by Duncan's test. The results showed that fish oil microencapsulation decreased blood cholesterol levels (P0.05). However, it did not affect body weight gain, consumption, and feed conversion (P0.05). Decreased levels of cholesterol occurred in the group of sheep with 2.5% microencapsulation (P1) and 5% microencapsulation (P2). Blood cholesterol levels of each treatment were 100.70 mg/dl (P0); 96.20 mg/dl (P1); and 78.76 mg/dl (P2), respectively. Averagely, the highest body weight gain, dry matter intake and feed conversion were found in P2 as much as 63.96 g/day, 574.13 g/day, and 9.08, respectively. The results can be concluded that microencapsulation of fish oil can reduce blood cholesterol, with the highest decrease at the level of 5%.
