Hubungan antara Ukuran-ukuran Tubuh dengan Bobot Badan pada Kambing Kacang di Kabupaten Grobogan, Jawa Tengah

Morphological performance can be used to characterize and to select livestock. Body weight can be estimated by body measurements. The objective of this study was to analyze the correlation between body measurements and body weight of Kacang goats in Grobogan Regency. Fourty one Kacang goats were used as materials. Kacang goats were grouped into different group of sex. Variable observed were body weight, face length, ear length, chest circumference, chest width, chest depth, body length, height at wither, height at hip, hip width, front leg length, hind leg length and tail length. Data observed were analyzed by using Statistical Analysis System (SAS ver 6.12). Results showed regression equation models of body measurements can be used to estimate the body weight of Kacang goat with coeffisient of determination of 81.4%-97.8%. Variable of body measurements used to estimate body weight of Kacang goat were face length, ear length, chest circumference, chest width, body length, height at wither and hind leg length

Keragaman Protein Plasma Darah pada Kambing Kejobong dan Kambing Peranakan Ettawa

The objective of this study was to evaluate the genotype variations of Kejobong and Ettawa Grade (EG) goats based on the blood plasm protein using gel polyacrilamide electrophoresis (PAGE). Twenty four of blood samples taken from Kejobong goat in Purbalingga regency and twenty four of blood samples taken from Ettawa Grade (EG) goat in Purworejo regency were used as materials. Data were analyzed to calculate gene frequency, individual heterozygosity and average heterozygosity. The independent t-test was performed to analyzed the significance of gene frequency, total genotype and average heterozygosity from six locus of blood plasm protein between Kejobong and Ettawa Grade (EG) goats. Result showed that locus of pre albumin (P-alb), albumin (Alb), ceruloplasmin (Cp), transferrin (Tf), post transferrin (P-tf) and amylase-I (Amy-I) on Kejobong and Ettawa Grade (EG) goats were polymorphic. The total genotype, gene frequency and average heterozygosity of six locus blood plasm protein between Kejobong and Ettawa Grade (EG) goats were not different. Average heterozygosity of Kejobong and Ettawa Grade (EG) goats was 0.423 and 0.435, respectively
