Enzyme Supplementation of Baby Pig Rations Containing Different Sources of Carbohydrate and Protein¹

Florida Agricultural Experiment Station, Gainesville²

Abstract

Two hundred and twenty pigs weaned at 9 to 11 days of age were used to evaluate the effects of supplementing various type rations with digestive enzymes. Sugar and/or corn were used in conjunction with combinations of dried skim milk, soybean meal, poultry meal and feather meal to form the major constituents in all rations.

There were no statistically significant differences in average daily gain between the control groups and the groups supplemented singly with diastase, pepsin and pancreatin or with various combinations of these enzymes; a similar situation existed when Ethmoid C/15 or sucrase was combined with these enzymes. The differences in gain, while small, were consistently in favor of the enzyme supplemented groups.

Feed efficiency was significantly improved (P<.05) for a 21-day period by the addition of pepsin, pancreatin and a combination of the two with and without sucrase to a ration composed essentially of sugar, corn, soybean meal and feather meal. Although in general the differences between the control and treated groups were not statistically significant, feed efficiency in most instances was improved by enzyme supplementation.

The performance of pigs fed enzyme supplemented rations for 21 days was similar to that of pigs supplemented over a 49-day period.

Pigs fed rations containing a dried skim milk-soybean meal combination gained significantly faster (P<.05) than those receiving a mixture of feather meal and soybean meal.
