Pattern of Growth Lengths, Circumference Chest and Body Weight of Bali Pig

The research in patterns of body length growth, chest circumference, and body weight of Bali pigs was carried out in the village of Musi, Gerogak district, Buleleng, Bali. This study aims to determine the measurement of body length, chest circumference and body weight during birth and the maximum growth size that can be achieved, as well as determining when the growth had reached inflection points and its adult size. The sample used in this study are Bali pigs at the age of 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, and 26 weeks, consisting of 2 males and 2 females. Data were analyzed with sigmoid regression analysis model, by determining the body length, chest circumference, body weight at birth, its maximum size, and as when it reaches the inflection point and maximum size based on the equation obtained. The results showed the body length, chest circumference, and body weight followed the sigmoid pattern. Male and female bali pigs during birth has the same body length, chest circumference, and body weight. While the maximum size of body length, chest circumference, and body weight were different between male and females. Most rapid inflection point of chest circumference was achieved at the age of 6 – 8 weeks, while the fastest adult size reached at the age of 32 - 34 weeks.
