Study of body measurement and feed intake in heifer and calf growth performance in the different topografi.

Abstract

The environment condition directly or inderectly influence animal performance, such as growth. Growth in animal was difine in many ways. One of its parameter is body growth. Location this riset was Cikole, Ciater and Cibungbulan in East Java and Pondok Ranggon in Jakarta. The present study was done in high, middle and lowland to observe wither height, body length (BL), chest width (CW), and heart girth (HG). 121 heads calves and and heifer 131 heads. Calipster and Rondo Ribon were used to measure the body size. The Gompertz model was used to predict the growth parameter of mature age. The age maturity for highland was 348-372 days, midleland 378 days, and lowland 466 days. The growth rate for all body size (BL, CW, HG) were higher in highland than midleland and lowland. The sequences of growth development from the Gompertz analysis were BL, CW, and HG respectively. Heifer which those early in puberty or mature age will reach better in body size.
