Forage mixtures for dairy cows: The effect on dry-matter intake and milk production of incorporating either fermented or urea-treated whole-crop wheat, brewers' grains, fodder beet or maize silage into diets based on grass silage



Forage mixtures for dairy cows: The effect on dry-matter intake and milk production of incorporating either fermented or urea-treated whole-crop wheat, brewers' grains, fodder beet or maize silage into diets based on grass silage



Animal Science 61(3): 491-496



One hundred and two multiparous Holstein/Friesian dairy cows were used to examine the effect on food intake and milk production of replacing 330 g/kg dry matter (DM) of first-cut perennial ryegrass silage (GS) with either fermented (FW) or urea (40 g/kg DM) treated (UW) whole-crop wheat, brewers' grains (BG), fodder beet (FB) or maize silage (MS). A forage mixture containing GS and 750 g/kg DM of maize silage (MSH) was also offered. Dietary crude protein (CP) concentrations were equalized by offering all cows 6 kg DM per day of an appropriate concentrate supplement. DM intake and milk yield of cows offered GS (15.3, 23.0 kg/day) were increased (P lt 0.01) by the inclusion of BG (16.3, 26-7 kg/day), FB (17.6, 25.9 kg/day), MS (16.6, 26.4 kg/day) and MSH (18.5, 27.6 kg/day). BG, FB and MS all produced similar increases in milk yield. Although the inclusion of FW and UW increased (P lt 0.05) DM intake, milk yield was not significantly affected. The differences between the highest and lowest milk fat concentration, produced by FB (42.9 g/kg) and BG (40.1 g/kg) respectively, and the highest and lowest milk protein concentration produced by FB (32.1 g/kg) and GS (29.9 g/kg) respectively, were statistically significant (P lt 0.001). Milkfat and protein yields of cows offered GS (0.97, 0.71 kg/day) were increased (P lt 0.01) by BG (1.07, 0.82 kg/day), FB (1.11, 0.83 kg/day), MS (1.11, 0.83 kg/day) and MSH (1.12, 0.88 kg/day). Intermediate values were recorded for FW (1.01, 0.72 kg/day) or UW (1.00, 0.73 kg/day). Results show that farmers should consider replacing a major part of the grass silage component with an alternative forage or forage substitute.
