Abstract

The lack of appropriate intestinal enzymes apparently limits the use of other carbohydrates to replace glucose and lactose in milk replacers.

The replacement of 20% lactose or glucose by wheat flour slightly reduced the digestibility of the organic constituents of the diet and a further slight reduction occurred when wheat flour was replaced by precooked maize starch. The relative digestibilities of these materials were: glucose, 100; lactose, 93.5; wheat flour, 71.5, and cooked maize starch, 62.5%.

Addition of a mixture of amylases and maltase reduced the digestibility of a milk replacer containing cooked potato starch.

Invertase addition immediately prior to feeding substantially improved the digestibility of a milk replacer containing 25% sucrose.
