Evaluation of Birth Weight and Body Measurements of Madura Cattle based on Year of Birth and Breeding System in Madura Breeding Centre, Indonesia

Abstract

This research was conducted to evaluate the birth weight and body measurement of Madura cattle based on year of birth and different breeding systems. The research was conducted in Technical Unit for Animal Breeding and Veterinary in Madura. A total of 137 Madura cattles born in 2014 to 2019 were observed for its birth weight (BW), chest girth (CG), body length (BL) and wither height (WH). The data were analyzed by using one-way ANOVA to understand the effect of year of birth on birth weight and t-test to analyze the effect of sex and breeding system on birth weight. The results showed that the mean BW, CG, BL and WH were 16.25±2.37 kg, 58.23±4.9 cm, 50.59±7.68 cm, 60.75±4.92 cm for Madura heifer and 17.08±2.4 kg, 59.12±4.04, 51.09±4.75, 63.78±4.07 kg for Madura bull calf, respectively. Birth weight of bull calf was significantly higher than the heifer (P=0.02). Moreover, the practiced natural mating in Madura cattle were higher (62.04%) compared to artificial insemination (37.96%). Birth weight of Madura cattle in 2014, 2015, 2016, 2017, 2018 and 2019 were 17.07±3.02 kg, 17.13±2.56 kg, 17.91±2.58 kg, 16.75±2.09 kg, 16.40±1.84 kg, and 18.01±2.38 kg, respectively. The research concludes that the BW, CG, BL and WH of Madura calves at birth were not significantly different between year of birth and showed uncertain patern.
