Optimum Weights to Which Pigs Should Be Carried in Puerto Rico for Maximum Profits

Abstract

A study on the feeding of swine at the Lajas Experiment Substation shows the maximum weights that animals of the Duroc Jersey and Landrace X Duroc breeds should reach for best yield and maximum profit. Pigs considered in this study entered feeding trials which extended from weaning at 56 days to 182 days of age. Feed consumed and gain in weight of the pigs was recorded every 14 days. Reference tables included were worked out on this basis.
