Abstract

A combination of sodium caseinate and sweet dried whey was compared to dried skim milk as a protein source for artificially reared piglets. Rate and efficiency of gain, diet consumption, frequency of diarrhea, nutrient balance and characteristics of the gastrointestinal tract and its contents were observed in piglets fed these protein sources. Rats were fed the same protein sources with rate and efficiency of gain, diet consumption, and frequency and severity of diarrhea observed. The combination of sodium caseinate and sweet dried whey was inferior to dried skim milk as a protein source for artificially reared piglets, the rate of gain being only 80 to 83% as fast for the group fed the casein-whey diet as for those fed the dried skim milk diet. Rats responded similarly. In both species the depressed rate of gain on the casein-whey diets was associated with more frequent diarrhea. Balance data did not show the dried skim milk diet to be superior, but reliable fecal collections could not be obtained from severely scouring piglets. No treatment differences were observed in the pH of the gastrointestinal tract contents, weight of empty stomach or histology of the gastrointestinal tract. Weight of stomach contents was greater in piglets fed the casein-whey diet.
