Gas Tight

Legume–grass forage was ensiled two seasons in 25-ton polyvinyl-encased stacks at dry matter (D.M.) levels of 22 to 37% or stored as field-cured hay. The polyvinyl sleeve coverings provided initial gas-tight conditions. High losses occurred in the high D.M. (32 to 37%) silage during the feeding-out period. Silage quality, as indicated by volatile fatty acid ratios, proximate principles, and digestibility coefficients, was not significantly influenced by D.M. content. When cows were fed the lower D.M. (22 to 29%) silages and hay, forage intake was inversely related to its dry matter content. Intake of high D.M. silage appeared abnormally low. Milk yields appeared to be more consistently influenced by small variations in grain intake than forage dry matter intake through both trials. Milk yields from silages were greater than from hay per unit of D.M. intake. Moisture content of forage had no significant effect on milk composition as indicated by percentage of butterfat, solids-not-fat, or protein.

Calving Difficulty

ABSTRACTThirty-nine Hereford × Friesian autumn-calving cows (mean calving date 17 September) and their Charolais-cross calves were used in a 2 × 2 × 2 factorial experiment to assess the effects of feeding level in winter and sward height in summer on intake and performance. Mean estimated metabolizable energy intakes during winter (30 October to 6 May) were 63 (L) or 92 (H) MJ/day. Two sward heights, 4·8 (SI) or 7·6 (Tl) cm, were imposed from turn-out to weaning on 3 July, and a further two sward heights, 4·7 (S2) or 8·0 (T2) cm, from weaning to housing on 1 October. At turn-out the H cows were 17 kg heavier (P > 0·05) than the L cows and their calves were 30 kg heavier (P < 0·01). Cow herbage intakes were significantly higher on the Tl and T2 treatments compared with the SI and S2 treatments as were live-weight changes: 0·94 v. –0·01 kg/day (P < 0·001) for Tl and SI treatments and 0·96 v. –0·18 kg/day (P < 0·001) for T2 and S2 treatments respectively. Calves on the Tl treatment had higher live-weight gains than those on the SI treatment (1·40 v. 0·63 kg/day; P < 0·001). After weaning the SI cows had significantly higher herbage organic matter intakes than the Tl cows (P < 0·05) and had significantly higher live-weight gains (0·51 v. 0·28 kg/day; P < 0·05). Calving difficulty and calf birth weight were not affected by any of the treatments. The results demonstrate that both previous and current level of nutrition have an effect on cow performance. When cows are turned out to pasture at body condition scores of 2·25 to 2·5, the sward heights recommended for spring-calving cows are equally appropriate for autumn-calving cows.
