Abstract

The purpose of this study was to describe the phenotypic profile of body weight at one year of male and female came from fraternal twins in Indonesian Local Ettawah Goat (ILEG) or PE Goat. This research method was a case study with data retrieval using purposive sampling with the criteria of male and female fraternal twins. The variables observed were the average and variance of body weight in fraternal twin goats at one year. Data analysed descriptive and unpaired t-test with excel program. The results showed that male goats’ body weight at one year of age was significantly (P < 0.01) higher than that of female goats at fraternal twins. At one year of age, the body weight variance in male goats was higher than that of female goats at fraternal twins. The conclusion was that the phenotype profile of male ILEG goats was more varied, seen from the average and diversity of body weight, which was 15.37% and 52.24% higher than females. This research implies that feeding male goats should be based on body weight, not on age, to increase their potential optimally.
