Abstract:The aim of this research was to analyze the correlation of age of Bali bull to the body weight and semen qualities. The materials were 50 Balibulls data collected from 2012 to 2018. Therecordeddatawere consisted ofsemen productions (n = 1304) and body weight (n = 1544). The observation was conducted to analysis the interrelationship between the Bali bulls age and body weight (BW), to the semen volume (SV), individual motility (IM) and sperm concentration (SC). The obtained data was analyzed with One-Way ANOVA analysisby using SPSS 24 and followed with Duncan’s Multiple Range Test to determine any significant differences. The correlation between Bali bulls age (the independent variable) and semen quality (the dependent variable) was computed by using Pearson correlation method and presented in linear regression models. The results showed that the Bali bulls agesignificantly affect (P

Abstract:The objective of this study was to evaluate the effect of manure at saline soil on forage production, quality and livestock carrying capacity of P. maximum and S. grandiflora. The research was conducted on moderately saline soil at Rembang Regency, Central Java Province, Indonesia.Randomized complete block design was used as design experiment. The treatments were different dosage of manure as organic amendment (0, 10 and 20 tonnes/ha). Forage crops were P. maximum and S. grandiflora that planted monoculture or mixed-cropping. Parameters measured were dry matter (DM) production, ash, crude protein, crude fibre, ether extract, total digestible nutrients. P. maximum was cut eight times, S. grandiflora was cut six times during one year. The result showed that the highest total dry matter production of mixed cropping P. maximum and S. grandiflora was available at moderately saline soil with application 20 ton/ha manure. Total production of dry matter, crude protein and total digestible nutrient available at application 20 ton/ha manure were 29131 kg/ha/year; 3722 kg/ha/year and 17718 kg/ha/year, respectively. Carrying capacity based on dry matter, crude protein and total digestible nutrients were 10.8 AU/ha/year; 13.6 AU/ha/year and 11.3 AU/ha/year, respectively. In conclusion, application of 20 ton/ha manure at saline soil increased production, crude protein and carrying capacity.

Abstract:The research objectives was to analyze the farmer’s decision in selecting breed of bull frozen semen for Artificial Insemination (AI) and determine the factors influencing the decision. There were five bull frozen semen options which simulated in this research, such as Simmental, Limousine, Ongole Grade (Peranakan Ongole / PO), Brahman, and other option. ”Other” option was used if the farmer did not recognize what breed of frozen semen was inseminated to their cow. Farmers must choose only one option of bull frozen semen that suitable for their cow. This study was conducted by collecting data using questionaire from 400 beef cattle’s farmers in Central Java Province and Yogyakarta Province. Respondents were selected by multistage random sampling technique. Descriptive statistical analysis and multinomial logistic regression analysis was used in this study The results revealed that 42% of farmers were more interested in inseminating their cows with bull semen from Simmental, and 30.75% of farmers were more interested in Limousin. Other variables such as family member, AI’s cost, land ownership, cow breed which lastly being inseminated, geographical factor, and farmer’s knowledge about the inseminatorswere variables that determine farmer’s decision process.

Abstract:The present study was conducted to analyze the broiler farmers’ capacity level in the partnership pattern and to analyze the factors which affect it. The current study was conducted in Bogor and Sukabumi, West Java Province using a survey approach on 247 farmers who ran farm businesses with the partnership pattern. Data were collected through questionnaire filling by farmers and in-depth interviews with key informants. The data were collected from July to October 2018. The data were analyzed descriptively and with inferential analysis (regression). The results of the study revealed that the farmers’ business capacity was weak. This was evident in the managerial and partnership capability which was categorized as low, the entrepreneurship and problem-solving capability which was categorized as medium, and only the technical capability which was categorized as high. The regression results demonstrated that business capacity was influenced positively by the formal education level, social environment characteristics (organizational support, access to experts), and the role of private extension agents (their role as educators, communicators, consultants, dynamizators, and organizers).

Abstract:The aims of this research were to improve the nutritive value of palm kernel cake by fermentation technology using Bacillus amyloliquefacien, Trichoderma harzianum and cocktail microbes (combination of Bacillus amyloliquefacien and Trichoderma harzianum). Data were analyzed using Completely Randomized Design Factorial, with experiments consisting of types of microbes (B. amyloliquefaciens, T. harzianum, microbial cocktail) as treatment and incubation time (0, 3, 5, and 7 days). Parameters were crude protein and crude fiber for all treatments, and the lowest fiber analysis would continue with NDF, ADF, crude fat, and amino acids. Result showed that the three of microbes grew on palm kernel meal in third incubation and grew on and in the substrate at 7 days. microbial cocktails increased protein and reduced crude fiber better than B. amyloliquefacien and T. harzianum on palm kernel cake fermentation technology. Cocktail microbes enhanced amino acids such as methionine, arginine, and glutamic acid, also neutral detergent fiber but reduced ADF and hemicellulose. It was concluded that the palm kernel cake fermented with microbial cocktails can reduced crude fiber and increase crude protein with an incubation period of 7 days.

Abstract:This study was aimed to explore the effects of Betaine-Homocysteine Methyltransferase (BHMT) gene polymorphisms on fatty acid traits and cholesterol in lambs. This study used a total of 147 blood samples for genotyping including 19 Javanese Fat-Tailed (JFT), 16 Javanese Thin-Tailed (JTT), 41 Composite Garut (CG), 35 Compass Agrinak (CA) and 36 Barbados Black Belly Cross (BC). A total of 61 rams as representative from five breed of sheep were selected for association study. Identification of BHMT single nucleotide polymorphisms was analyzed by PCR-RFLP method. Association of BHMT genotypes with fatty acid traits and cholesterol was performed by T-TEST. BHMT genotyping resulted into three genotypes (CC, CT and TT). Gene frequency of BHMT (g. 9947372 C>T) was in Hardy-Weinberg Equilibrium, excluding Javanese Fat-Tailed sheep. Association of BHMT genotypes with fatty acid traits resulted into a significant association (PT) of BHMT gene might be a useful marker for selecting and producing sheep meat with desirable fatty acids.

Abstract:This study was completed to investigate the breed factor that influences milk production in different goat breeds in the tropical environmental area. A total of 28 goats were utilized in this work. These goats consisted of two different breeds, which were Anglo-Nubian and Saanen. Blood samples were withdrawn through jugular veinsof goats into plastic tubes without EDTA for gene polymorphism. A t-test was used to analyse if there are any significant differences in molecular weight and frequency values of DNA between breeds. Investigation of DNA polymorphism in alleles A, B and C of α-casein were identified in all breeds, while allele F were studied in Saanen goats only. As a conclusion; Saanen goats have more varieties α-casein allele

Abstract:The objective of the present study was to evaluate the impact of dietary supplementation of formic acid, butyric acid or their combination on carcass and meat characteristics of broiler chicks. A number of 288 day-old-chicks (Lohmann MB-202 meat broilers) were distributed to four groups, including CONT (basal diet with no additive as a control), FORM (basal diet containing 0.1% formic acid), BUTR (basal diet with 0.03% butyric acid) and FORM+BUTR (basal diet with 0.1% formic and 0.03% butyric acid). At day 35 the birds were slaughtered and eviscerated, and from which the breast meat was obtained. Carcass and cut yields of broilers were not different (P>0.05) among CONT, FORM and BUTR birds. The combination of formic and butyric acids increased (P
