Abstract
Analysis of the sales of surplus calves to Ministry of Food collecting centres in West Wales during the four years 1943–46 reveals the interesting fact that there is a fall in the percentages sold during the autumn months (September–December) from coastal to inland centres and from centres in the west to those in the east. Autumn deliveries to the milk depots in the region show the same trends: thus factory F in the west received during the month of December (average of the four years 1943–46) 94·6 per cent of its September deliveries, whereas factories C, D and G in the eastern areas received only 53·9, 52·7 and 52·1 per cent respectively. There is therefore considerable evidence that the coastal areas, and particularly West Pembrokeshire, have a higher incidence of autumn calvings.
