Abstract

An evaluation was conducted of the returns to fattening cattle of small- and medium-scaleenterprises in East Java. The objective was to analyze income over feed costs (IOFC) based on locallyavailable feedstuffs to increase liveweight gain. The study was conducted during July-September 2010and January-March 2011, representing relative dry and wet season. The breeds were PO and Limousinand Simmental crossed with PO (LimPO and SimPO). Small-scale farmers owning 1-2 bulls andmedium-scale farmers fattening 10-20 bulls in one period. Fattening period was 58 and 46 days,respectively for dry and wet season. Monthly measurements included liveweight, feed intake, input andoutput prices. Mean values of growth rates and IOFC were compared using t-tests. The results indicatedthat, for small-scale operations, SimPO bulls gave a significantly higher return than either PO or LimPObulls. Likewise, LimPO gave a higher IOFC than SimPO in medium-scale operations. Small-scalefarmers achieved equal or higher IOFC for European-cross than medium-scale farmers in both seasons.This reflects that cash outlays for feed were about two-thirds that of medium-scale operations whiledaily growth rates were similar. Small-scale fattening operations using European-cross can befinancially competitive with medium-scale operations in both wet and dry seasons.

Abstract

Parboiled rice product has been widely produced by industry in the developing countries. The increasing of parboiled rice product will consequently increased rice bran waste. Therefore, the objective of the study was to analyze the effect of parboiling processes on nutritional value of rice bran and evaluate nutritional value of parboiled rice bran in the rumen fermentation using in vitro digestibility method. The experiment was arranged in completely randomized factorial design with 2 factors and 3 replications. The first factor is types of rice bran from different rice plant variety consisted of LIPI GO1, LIPI GO2, LIPI GO4, and Sintanur. The second factor is soaking time consist of 0 minute (control), 30 minutes and 60 minutes. Data were analyzed by using ANOVA and significant effects of each treatment were further analyzed by using the least significant difference by Duncan multiple range test (P<0.05). Kinetic parameters of Ørskov’s equation were obtained by non-linear regression procedure. Results showed that the quality of parboiled rice bran was significantly affected by the parboiling process such as soaking periods and rice variety. Chemical composition, rumen gas production, and digestibility of rice bran differ depends on rice variety. Soaking for 30 minutes and 60 minutes decreased organic matter, crude protein, and increased crude fiber (P<0.05). Moreover, soaking rice grain for 60 minutes increased crude fat. The longer of soaking periods decreased of total gas, potential gas production, gas production rate and total organic matter digestibility (P<0.05).

Abstract

An experiment was conducted to evaluate the effect of type of feed and slaughter age on the performancesand carcass characteristics of male Arab chicken. Thirty six male Arab chicken of seven weeks old weredivided into two groups, each group consisted of three cages with six chicken in each group. Two types ofration consisted of Ration One (Par-S + corn) containing 2904 kcal ME and 17 % CP, and Ration Two (BRII) containing 3100 kcal ME and 19% CP. The chicken were raised for seven weeks, weekly weighed, andrandomly taken for slaughter at 12 and 14 week old. The data collected were performances and carcasscharacteristics of the chicken. The data were analyzed using analysis of variance of completely randomiseddesign. The results showed that the chicken fed BR II consumed more protein and energy (483.7 g CP and7868.8 kcal ME) compared to the chicken fed BR I (444.0 g CP and 7586.1 kcal ME). Besides, the chickenfed BR II produced heavier final body weight (1142.5 g) than the chicken fed with BR I (1048.6 g) (P <0,05). Type of ration affected the tenderness of chicken. Slaughter age influenced carcass weight andcarcass physical composition of the chicken (P<0.05). Slaughter age affected the physical characteristic ofmeat. It could be concluded that male Arab chicken fed ration containing higher CP and ME (higher feeddensity) consumed more protein and energy, and finally had heavier final body weight. Slaughter age influencedcarcass weight, carcass physical composition and meat characteristics of the male Arab chicken.

Abstract

The purpose of this research was to study genetic diversity in Indonesian sheep population usingmicrosatellite markers. A total of 18 microsatellite loci have been used for genotyping Indonesian sheep.Total sheep blood 200 samples were extracted from garut sheep of fighting and meat types, purbalinggasheep, batur sheep and jember sheep populations by using a salting out method. Microsatellite loci datawere analyzed using POPGENE 3.2 software. Based on this study obtained 180 alleles from 17microsatellite loci, while average number of alleles was 6.10 alleles (6 to 18 alleles) from fiveIndonesian sheep populations (garut sheep of fighting type, garut sheep of meat type, purbalingga sheep,batur sheep and jember sheep population). The average of observed heterozygosity (Ho) and expectedheterozygosity (He) values were 0.5749 and 0.6896, respectively, while the genetic differentiation forinbreeding among population (FIS), within population (FIT) and average genetic differentiation (FST)were 0.1006, 0.1647 and 0.0712, respectively. Genetic distance and genetic tree showed that Indonesiansheep population was distinct from garut sheep of fighting and meat types, purbalingga sheep, batursheep and jember sheep population. Based on this results were needed a strategy for conservation andbreeding programs in each Indonesian sheep population.

Abstract

This study aimed to compare the antibiotic resistance patterns among original Enterobacteriaceae isolates from broiler and backyard chicken meats in Surabaya, Indonesia, isolated in 2016-2017. The Kirby–Bauer disk diffusion method was used to determine the resistance of these isolates against tetracycline (TE), gentamicin (CN), cefoxitin (FOX), sulfamethoxazole-trimethoprim (SXT), nalidixic acid (NA), and chloramphenicol (C). Both broiler and backyard chicken meat isolates were resistant to the six antibiotics tested. Overall, broiler meat isolates which resistant to TE, CN, FOX, SXT, NA, C were 57.76% higher than backyard chicken meat isolates. More than 50% of broiler meat isolates (304 samples) were resistant to TE and NA, whereas backyard chicken meat isolates (310 samples) were only resistant to TE. The resistant strains found in both meat isolates were Salmonella spp., Escherichiacoli, Shigella spp., Citrobacter spp., Klebsiella spp., Yersinia spp., Proteus spp., Enterobacter spp., Serratia spp., and Edwardsiella spp. Resistant strains of broiler meat isolates were significantly higher (P<0.05) than backyard chicken meat isolates, except Edwardsiella spp. Overall, multidrug-resistant Enterobacteriaceae was found to be higher in broiler meat isolates than in backyard chicken meat isolates. Broiler and backyard chicken meats are potential reservoirs of multidrug-resistant Enterobacteriaceae which threat to public health.

Abstract

The objective of this study was to obtain enriched eggs with low cholesterol content. Forty-eight laying hens (strain Dekalb Warren) aged 72 weeks were distributed into six treatment groups as follows: 1) Laying hens fed diet without Sauropus androgynus leaf extracts (SALE), fish oil and vitamin E (P0) as the control; 2) Laying hens were fed diet with 27 g SALE/kg diet, but without fish oil (P1); 3) Laying hens were fed diet with 27 g SALE/kg diet, 1.5% fish oil (P2); 4) Laying hens were fed diet with 27 g SALE/kg diet, 1.5% fish oil and 60 mg vitamin E/kg diet (P3); 5) Laying hens were fed diet with 27 g SALE/kg diet, 3% fish oil (P4); 6) Laying hens were fed diet with 27 g SALE/kg 3% fish oil and 60 mg vitamin E/kg diet (P5). Experimental results showed that the treatments affected (P <0.05) egg production, thick eggshell, egg white height, yolk color, the odor of eggs after the split (P <0.05). It was shown that the treatments had no effect on the contents of protein, fat, β-carotene of eggs but affected the contents of cholesterol and vitamin E of eggs. In conclusion, the treatments improved egg quality and increased egg Vitamin E but reduced egg cholesterol.

Abstract

This experiment was aimed to investigate the effect of combining tannin and saponin extracts onruminal methane emission of diets with different proportion of forage to concentrate in the in vitrofermentation. The experiment was conducted in a factorial block design. The first factor was theproportion of forage:concentate in diets (70:30 and 30:70) and the second was addition of tannin andsaponin extracts (control, tannins, saponins, tannins + saponins) in the dose of 2 mg/ml. Variablesobserved were gas production kinetics, methane production, dry matter digestibility (DMD), organicmatter digestibility (OMD) and ammonia concentration. Results revealed that addition of tannins,saponins and their combination generally lowered total gas and methane production during 24 and 48 hof incubation period in both types of diets (P<0.05), but combination of tannins and saponins comparedwith their separated forms did not show any significant differences. The addition of tannins, saponinsand their combination reduced DMD, OMD and ammonia significantly (P<0.05). It can be concludedthat the addition of tannin, saponin and their combination at a dose of 2 mg/ml could reduce methaneemission but followed by a decline in the DMD, OMD and ammonia.
