Abstract

The study was aimed determine the growth pattern of body weight of female Kacang goat in Grobogan. The research was done by survey and used 150 female Kacang goats aged from 0-3 months many as 23 materials,> 3-6 months many as 29 materials,> 6-9 months many as 21 materials,> 9-12 months many as 11 materials,> 12-18 months many as 15 materials,> 18 -30 months many as 16 materials,> 30-42 months many as 16 materials and age> 42 months many 20 as materials. The location and the sample were determined by purposive sampling method based on the Kacang goat population, sex and age. Body weight of Kacang goat was measured by weighing manually.
