Amino Acid Supplements to Milo-Peanut Meal Rations for Growing Pigs

Abstract

Two experiments involving 324 pigs were conducted to evaluate milo-peanut meal in starter and grower rations. Corn-soybean meal rations served as positive control.

The 16% crude protein milo-peanut meal grower ration was nutritionally inadequate for pigs from 18 to 50 kg. in weight in pasture and drylot environments. Addition of either 0.13% lysine, 0.13% lysine plus 0.13% methionine, 3.0% fish meal, or 3.0% fish meal plus 0.10% methionine significantly improved rate of gain. This increased performance was associated with increased feed intake of the supplemented rations. None of these supplemented rations, however, produced gains equal to those from 16% corn-soybean meal rations.

Levels of 4.0, 6.0, 8.0, and 10.0% fish meal in a 20.0% crude protein milo-peanut meal-base starter ration produced significantly faster gains and better feed efficiency than the milo-peanut meal ration. In these rations calculated to be isonitrogenous, maximum gain and best efficiency were obtained at the 8.0% level of fish meal. However, the highest level of performance from the fish meal supplemented milo-peanut meal rations was significantly less than that from the corn-soybean meal starter ration.

Supplementation of the milo-peanut meal rations with either lysine, lysine and methionine, fish meal, or fish meal plus methionine presumably improved the amino acid balance of the rations, particularly correcting the primary deficiency of lysine.
