Feather Meal as a Source of Protein for Growing-Finishing Swine¹

Florida Agricultural Experiment Station²

Abstract

Two experiment involving 48 group-fed and 24 individually-fed weanling pigs were conducted to study the value of feather meal as a protein supplement for swine.

Three levels of feather meal were studied and the growth rate was found to be significantly influenced by the level fed. Pigs that received the ration containing 10% feather meal gained significantly slower than pigs fed any of the other rations.

Daily gains were significantly lower for pigs fed 7% feather meal than for those fed the basal or 5% feather meal. Supplementation of the 7% feather meal ration with 0.27% DL-lysine resulted in an improved rate of gain when compared to the unsupplemented ration (Experiment I); and, when the lysine supplement was increased to 0.46%, (Experiment II) daily gains were significantly increased.

The addition of Bovirum to the 7% feather meal ration had an adverse effect on pig performance.

No significant differences were obtained among the growth rates of pigs fed the basal, 5% feather meal or 7% feather meal plus lysine rations.
