On this point also the verdict is against the common belief, as Messrs. Mackenzie and Marsh have carried out a series of investigations at Cambridge which clearly proved that seedy bellies were equally as common when the sow pigs were not in heat and when they were; but that the discoloration which resembles numbers of small spots of colour varying from dark blue to light red in the mammary glands is merely an excess of pigment, the darker shade being common in pigs with dark coloured hair and skin such as the Large Blacks, Berkshires, etc., and the lighter shade in pigs of the Tamworth breed. In the bacon manufactured from pigs with a white skin and white hair there is no discoloration or seedy bellies. Although it has been generally considered by bacon curers that pigs of a white colour were preferable for their trade, and this to such an extent that some of the bacon curers in Ireland will pay a slightly higher price for a pig with a white skin, the preference was generally considered to be due to the more presentable appearance of a side of bacon from a white than from a black pig; it would appear that in the future a still greater preference will be observable when it becomes generally known that the bacon made from white pigs is free from seedy bellies. * * * * * _To make money out of Pigs_ One must go on the NON-STOP PRINCIPLE, every little check to growth means so much less profit.
