Abstract

Seventy-two pigs between 7 and 28 days of age were given diets containing milk, fish or soya bean proteins in two separate experiments. In the first experiment, the weight gains of pigs given casein, isolated soya bean protein, fish meal and soya bean meal were 211,180,200 and 191 g/day, respectively, and the food conversion ratios were 0·84, 1·16, 0·93 and 1·10, respectively.

In the second experiment, the protein sources were skim milk, casein, isolated soya bean protein, soya bean concentrate and soya bean meal; weight gains of the pigs on these respective diets were 205, 180, 154, 133 and 169 g/day, and the food conversion ratios were 0·81, 0·92, 0·97, 1·07 and 1·05.

Apparent digestibilities of the soya bean and fish protein diets were less than those of milk protein diets. Apparent digestibilities of all diets increased between the collection periods at 9 to 14 days and 23 to 28 days of age.
