title: Growth and skeletal development of the pig.
abstract: Growth and skeletal development of the domestic pig (Swedish landrace and Yorkshire) are reported and the weight curve of males from birth to maturity included. Other parameters were tooth development and growth of certain bones. It was concluded that daily weight gain increases rapidly to an age of about 5 months. Sexual maturity is reached by both the male and female pig at about 5--6 months of age. At this time there is an inflection point on the weight curve. The period from 5--6 months to about 18 months of age is called adolescence. After 18 months of age the weight curve is flattened. The data from the domestic pigs were compared with the corresponding data of the wild European hog. It was found that the wild hog has a much slower weight gain.
