Extract

Mansbridge (1995) reported that replacing ground wheat with a mix of ground wheat and maize grain increased milk protein concentration, which led the authors to speculate that increased inclusion of maize grain increased rumen by-pass starch. Indeed, de Visser et al (1990) reported that feeding less rapidly degradable starches has led to increased milk protein concentration.

The objective of this study was to examine the effects of starch concentration and source on feed intake, milk yield and milk composition of dairy cows.
