Abstract

This study aimed to test the reliability or accuracy of various types of tape measure and develop a model of the measuring tape and weight estimation formula based on cow size chest circumference Peranakan Ongole, cross Brahman cattle, Limousin Cattle, Cattle Bali and Aceh cattle. Research conducted at BPTU-HPT Indrapuri Aceh, Desa Tanah Raja Sei Rampah Bedagai Serdang, Oil Palm Research Center (PPKS), Livestock People in Tanjung Morawa Serdang Bedagai, and Livestock of the people in the village of Big Two Falls Pantai Cermin District Serdang Bedagai , The research was conducted from May to September 2015. The tape measure used in this study is the measuring tape Agrotech, Animeter and Rondo, then use a formula Schoorl and Smith as a comparison, as well as using a simple correlation analysis in testing research data. The result showed that the estimation of body weight for cattle crossbreed ongole, Brahman cross cattle, cows limousines, bali cattle and cattle Aceh using a measuring tape Agrotech, Animeter and Rondo obtained deviation of 30.03% for male cattle and 16.23% for livestock female. Conclusion estimation of body weight that comes closest to the ongole crossbreed cattle, Brahman cross cattle, cows limousines, bali cattle and cows Aceh is using a regression formula, namely for male animals Y = - 405.70 + 4,33X and for female animals Y = - 448.64 + 4,72X.
