Genetic Diversity of Bali Cattle in Barru Regency Based on Phenotype Characteristics and Microsatelite DNA Identifier
Full text linkSapi Bali is one of Indonesia germplasm, which has great potential to be developed as a national meat suppliers. Barru regency, South Sulawesi province is one of the purification center of Bali cattle in Indonesia. This study aimed to determine the genetic characteristics of Bali cattle in Barru regency based on identification of phenotype qualitative (horn shape and color of feathers) and quantitative traits (body size), as well as the identifier of microsatellite DNA diversity, in particular HEL9 and INRA035loci. Bali cattle phenotype characterization was done by identifying the typical qualitative properties owned by Bali cattle, as well as a quantitative trait such as body weight, body length, chest circumference and height. Blood samples were collected from about 80 heads of Bali cattle (35 males and 45 females). Extraction of genomic DNA using a DNA extraction kit (GeneJet Genomic DNA Extraction). PCR technique was then used to amplify DNA in microsatellite HEL9 and INRA035loci. Genetic diversity was calculated based on the frequency of alleles and genotypes, observed heterozygosity (Ho), expectated heterozygosity (He) and the Hardy-Weinberg equilibrium. The results showed that the predominant form of horns in males were silak bajeg while the females were silak manggulgangsa, while the percentage of normal color pattern (typical of Bali cattle) was 92.5% and the color pattern deviates ie. 7.5%. In HEL9 locus, alleles found were A and B with only AB genotype(100%). While at the INRA035 locus,were found three alleles ie. A (0.4813), B (0.50) and C (0.0187), with the most common genotype were AB (0.96). Based on shape horn and feather color, the phenotype characteristic of Bali cattle in the Barru regency were quite diverse, but the genetic diversity of DNA microsatellite observed quite low with only found two alleles (A and B) at HEL9 and 3 alleles (A, B and C ) at the INRA035 locus
The Influences of Transaction Costs on Dairy Farming system in South Sulawesi Province
Full text linkThe research aimed to 1) identify transaction cost in small holder dairy farm operating either under partnership or independent system, 2) analyze the influence of transaction cost for dairy cattle business system, in South Sulawesi. The research was carried out from November 2009 to March 2010 at two different regions based on the farming system practiced, namely for partnership system in Sinjai Regency and for independent system in Enrekang Regency. Descriptive analysis was applied to identify the first aim of study and the logic model was adopted to analyze the second one. For the latter, 30 farmers for each system were deeply interviewed. The results of this research showed that (1) transaction cost of partnership system was lower than that of independent system, (2) transaction cost, particularly transportation cost, had significant influence on partnership system
Antioxidant and Antihypertensive Activity Egg White Powder Produced by Pan Drying at Different Temperature and Drying Time
Full text linkAntioxidant and antihypertensive (ACE-Inhibitors) are commonly known as bioactive molecules in foodstuff. Both molecules can be obtained naturally or through processing and preservation of egg white of poultry eggs. One way of preserving the egg white with drying method is by pan drying method. The objective of this study was to determine an appropriate temperature and drying time to produce high yield of antioxidant and antihypertensive activity. The materials used for this study were 900 eggs which were obtained from the same farm. That amount was calculated based on the number of experimental units required to run the experiment with the total number of treatment (3 x 3) with 4 replications for each treatment combination giving 25 chicken eggs for each treatment. The experiment was carried out using a 3x3 factorial arrangement according to completely randomized design. The first factor was drying temperature, i.e. 45oC, 50oC, and 55oC and the second factor was drying time, i.e. 30h, 39h, and 48h. The results showed that high antioxidant activity was found on egg white which was dried at temperature of 45oC for 39 hours which reached 26.85%. However, antihypertensive activity was optimum at 50oC and drying for 48 hours, which was up to 75.06%. Drying the egg white using appropriate temperature and time may improve the antioxidant and antihypertensive activities
Analyze The Contract of Broiler Partnership Farming System in the Province of South Sulawesi in Conjunction to the Law No. 5, 1999 Regarding Prohibition on Monopolistic and Unfair Business Competition
Full text linkThis research aimed to analyze the contract of broiler partnership farming system in the Province of South Sulawesi in conjunction to the Law No. 5, 1999 regarding prohibition on monopolistic and unfair business competition. This research was carried out from August 2013 till October 2013 in Maros and Gowa Districts of South Sulawesi. All broiler farmers were treated as the population of the study and farmers having contract with any company in the region were taken as the samples giving total number of sample was 50 farmers. The results of study showed that the implementation of partnership was in line with the contract. However, there were some points of the contract which were not well implemented by both parties, such as the late harvest time and the late payment in which these did not comply with the Law No. 5, 1999
