Whole crop wheat (WCW) appears to offer an attractive alternative forage to grass silage for dairy cows, particularly in those areas where maize silage cannot be grown. However in previous feeding trials the inclusion of WCW with grass silage has increased food intake but has not led to a corresponding increase in milk yield (Phipps et al,1993). As part of a programme to try to overcome the low efficiency of diets containing WCW, the present experiment was designed to examine the effects on feed intake and digestibility and milk production of the step-wise replacement of GS by urea-treated WCW.Winter wheat (cv Hussar), harvested at 620g DM/kg fresh weight and preserved with 20 or 40 g urea/kg DM (WCW-2, WCW-4) was compared with first-cut perennial ryegrass silage (GS). Six multiparous Holstein-Friesian cows in mid-lactation were offered six diets over three 4-week periods in an incomplete change-over design. Diets were 6kg DM concentrates daily with forages ad lib. Treatments (DM basis) were GS alone, 2:1 GS:WCW-2 or WCW-4, 1:2 GS: WCW-2 or WCW-4, and WCW-4 alone. Feed intake and milk production were measured in weeks 3 and 4 and digestibility in week 4.

Forty Holstein–Friesian cows were fed concentrate at one of five levels (0.15, 0.20, 0.25, 0.30, or 0.35 kg concentrate/kg milk produced) and alfalfa hay to appetite. In a 280-day lactation period with twice-a-day milking, average milk production was 19.9 kg/day and increased 0.150 kg/0.01-kg increase of concentrate per kilogram of milk produced (P < 0.05). The rate of change in milk production, feed intake, and milk constituents was not affected by the breed–class–average (BCA) index of the cows over the BCA range studied. For each 0.01-kg increase in concentrate per kilogram of milk produced, daily increase in production of solids-not-fat was 0.0138 kg and of protein was 0.0052 kg (P < 0.05). Total energy secreted in milk increased, but not significantly, as the level of concentrate feeding increased. However, the proportion of energy consumed that was secreted in the milk declined from 26.8 to 23.5% (P < 0.10) as the level of concentrate feeding was increased.

The effect of dietary crude protein (CP) level on intake, digestibility, milk production, and nitrogen (N) use efficiency was studied. Twenty-four Holstein-Friesian cows (17 multiparous and seven primiparous) were grouped by parity, days in milk, milk yield, and live weight into six blocks of four, and randomly assigned to four total mixed ration (TMR) treatments, containing 141, 151, 177, or 210 g CP/kg dry matter (DM), over 28 day experimental periods. Apparent total-tract DM and fiber digestibilities and milk fat composition were similar across treatments. Milk protein and urea-N compositions, and urinary and manure N excretion increased linearly, while milk N efficiency (MNE) decreased linearly with increasing CP. DM intake was highest with the 177 diet, while CP intake increased linearly with increasing CP, peaking at 200 g/kg DM. Milk yield increased with CP intake for the three lower CP levels, peaking at 176 g CP/kg DM. The further increase in CP level from 177 to 210 g/kg DM did not result in improved milk yield, but resulted in decreased milk N secretion and increased urinary N excretion. In summary, milk protein composition increased linearly with increasing CP, accompanied by a linear decrease in MNE, resulting in a bell-shaped relationship between milk yield and dietary CP level.
