Goat Nutrition DCD9

DCD9 65-Percent Concentrate Late Lactation Diet

The 65-percent concentrate diet shown below was used in an experiment in late lactation. The level of milk production by doelings supported by this diet was similar to that of other dietary concentrate levels. However, milk production by does consuming this diet was less than production by does consuming a 50-percent concentrate diet (DCD8). Similarly, other researchers have suggested that milk production by dairy goats may not necessarily be greater with high- versus moderate-dietary concentrate levels, as is the case with dairy cows. Trace mineral and vitamin premixes are those used for CD2. The calculated composition on a dry matter basis is:

CP – 16.4%
ME – 2.62 Mcal/kg
NEl – 1.66 Mcal/kg
Ca – 0.80%
P – 0.40%
