The procedure for determining the season of slaughtering of pigs on the basis of age at the time of death is discussed. The starting points of this procedure, the frequency and time of birth, are contested on the basis of biological and historical data. The factors that determine the frequency and time of birth of pigs, that must be known for the correct use of this procedure are described. 相似文献
