Abstract
It is suggested that the seasonal distribution of the sale of surplus calves through the collecting centres of the Ministry of Food in west Wales during the years 1943–6 is a reasonably accurate reflexion of the rate of calving in the areas associated with these centres. It is shown that between the centres there is a considerable difference in the seasonal distribution of calf sales, and that the percentage numbers of autumn calf sales (September to December) show a gradual decline from the westerly coastal centres to the easterly inland ones. It is also found that the figures for the milk production and particularly the milk deliveries into the factories during the period September to December support the above suggestion.This publication has 7 references indexed in Scilit:
