Abstract: A method and composition for increasing the quantity and quality of the milk produced by lactating mammal subject to lactation failure or MMA syndrome which frequently occurs after giving birth to off-spring and which comprises orally administering to a lactating mammal, such as a farrowing sow or gilt, a composition comprising a combination of diuretic and cathartic components in proportions which maintain the electrolyte balance so as to avoid dehydration of the mammal while effectively removing excess fluid from mammary tissue via the kidneys and the intestinal tract and which in a preferred form is comprised on a weight basis of 65 percent sodium sulfate, 13 percent magnesium sulfate monohydrate, 12 percent sulfur and 10 percent anhydrous potassium sulfate, and said composition preferably being admixed with a complete feed for the lactating mammal in an amount of at least about 0.5 wt. percent or top-dressed on the feed at a rate of one ounce per day for a mammal such as a lactating sow.

Abstract: A nutritional and therapeutic source of iron comprising an orally administrable composition having as the essential source of iron the reaction product of one molar equivalent of a ferrous iron salt and at least two molar equivalents of glycine and said ferrous iron in said reaction product being in a non-ionic form with each ferrous iron molecule having two glycine molecules ionically bonded therewith and preferably also having six molecules of glycine associated therewith by covalent bonds and said reaction product when orally administered in a liquid or solid feed mixture or in an aqueous solution to mammals effecting a significant increase in the concentration of iron in the blood of the mammals.
