Morphometrics of Etawah Grade goat females as dairy breeding stocks under intensive management system in Central Java

Abstract

Body measurements and their intercorrelations can be used as initial indicators of measurements, and to estimate chest girth from other body measurements in EG goat females kept under intensive management at one government dairy station in Purwokerto District, Central Java. Samples were Etawah Grade (EG) goat performance-based selection for good EG dairy breeding stocks. The aims of this research were to study characteristics of morphometric, to investigate intercorrelation among body females specified as breeding stocks of dairy goat type kept under intensive management of the Government Dairy Breeding Station at BBPTU Baturraden, Purwokerto District, Central Java. A total of 50 EG females between the ages of 1-6 years old were measured for some body measurements. Averages of body measurements of the observed EG goat females increased by the ages. The averages of body sizes at the ages of 2 years old for SH, HH, BL, CG, and HG were successively 75.011.1 cm, 79.81.8 cm, 65.31.8 cm, 77.03.9 cm, and 82.80.4 cm. At the mature ages (5 years old), compared to the young ones (2 years old), EG females had higher values of SH, HH, BL, CG, and HG by 6.3%, 1.8%, 17.9%, 18.0%, and 16.3%.CG had the highest correlation to HG (rs = 0.837-0.858) and CG was accurately predicted by HG or by the combination of HG to other body sizes. High intercorrelations were found among certain body measurement(s) of the EG dairy goat females.
