Summary

From 50 to 140 lb liveweight pigs were given mixtures containing 25 or 50% of either un-neutralized or neutralized lactic casein whey powders in partial replacement of barley meal in a control ration.

Those animals that were given rations containing 25 and 50% un-neutralized whey powder and 25% neutralized whey grew significantly faster and more efficiently up to 110 lb liveweight than the controls and those given the rations containing 50% neutralized whey powder. For the overall trial period, only differences between the last-named group and each of the 3 other groups that received whey powder were statistically significant.

Water intake increased with level of whey powder in the diet and was significantly greater at both levels with the mixtures containing the neutralized powder than with the other diets.

Carcass measurements did not indicate any significant difference in treatment.

Both whey powders were sticky and unpleasant to handle, the neutralized material being worst in this respect.
