PIG AILMENTS.

PROFESSOR CARROLL’S ADVICE.

In a recent article Professor

Carroll, professor of swine husbandry, Ulinios University, U.S.A. states that, providing the diet includes either tankage (slaugh-ter-house offal), or sufficient skim milk or whey, minerals need not be supplied independently to pigs, with the possible exception of salt.

However, one encounters a type of paralysis in Digs due to deficiency in supply of assimilation of calcium. Disease due to deficiency is recognised. lodine in some form supplied to preg-

nant sows has overcome troubles such as hairlessness, goitre, weakness, or small number of the new litters, and is also proved to produce more rapid growth with the same amount of feed. “I think, therefore,” says the professor, “that the standard mineral mixture—steamed bonedust 501 b., salt 121 b., sulphate of iron exsiccated lib., potassium iodide 2oz—made available in a small trough apart from the feeding trough would be quite beneficial. Pigs are somewhat susceptible to salt poisoning, so only small quantities should be put out at first. Alternatively, the steamed bone-meal alone may be put on in the trough, and loz. of potassium dissolved in a quart of water and added to the feed at the rate of I teaspoonful per pig per day for pigs half-grown and UDward.”
