Iberian Red Deer

Social rank in cervids and other mammals is not entirely predicted by body weight, but in most cases influences access to food directly. Milk provisioning depends on maternal weight and on daily food intake. Usually, body weight, body condition, age and social rank are inter-correlated making it very difficult to discern the relative importance of each variable to milk production. This study used path analysis to assess direct versus indirect effects of these variables on milk production of 62 Iberian red deer hinds (Cervus elaphus hispanicus). Once the known direct effects of body weight and body condition were set as fixed, hind age and social rank did not affect milk production directly. In contrast, they exerted an indirect influence through the correlation both with hind body weight and body condition. Body weight exerted an effect on milk production nearly twice as great as that of body condition. This study shows, for the first time in a wild mammal, the relative importance of social rank, body weight, body condition and age in affecting milk production ability.

Angus Heifers

Thirty-two early-summer-calving Angus heifers received 4 rations in early lactation for the last 92 days of drought and then grazed pasture. The aim was to produce calves suitable for slaughter at weaning (i.e. at about 11 months of age) and to maintain the usual calving rate of about 85% at the next calving. Variations on the control ration of 83% cracked wheat and 17% long oaten hay, plus minerals and vitamins, were 44% hay or additions of urea or sodium bicarbonate. The calves received 0.33 kg and later 0.66 kg of pasture hay/head.day. The nitrogen content of the respective rations was 19.3, 17.5, 24.3 and 19.3 g/kg of dry matter. The apparent digestibilities of the organic matter were 66, 68 and 88% for the pasture hay, oaten hay and cracked wheat, respectively. There was no acidosis, but the heifers would only consume at 80% of the intended level of 6.0 kg/head.day for the control ration. Heifer condition score, weight change and milk composition, and calf growth and milk consumption, did not differ (P>0.05) between treatments. The average daily liveweight changes during drought feeding were -0.51 kg for the heifers and +0.64 kg for the calves. There was a tendency to slower eating and fewer calves at the next calving with the urea and bicarbonate rations. The calves were all of slaughter condition at weaning, and on average 84% of the heifers calved at the next calving. The control ration appeared to contain adequate roughage and nitrogen for milk production. The heifers' energy requirement in relation to milk production and liveweight performance was as predicted by the common feeding standards. Feed consumption, although lower than intended and probably constrained by the mineral content of the diet, was adequate in heifers that were initially fat enough to tolerate prolonged weight loss.

Average Body

The effect of pre-calving hind body condition and the interaction with pasture forage mass during lactation on calf growth and intake to weaning were investigated. Two-hundred and forty red deer hinds (Cervus elaphus scoticus × hippelaphus) of average body condition score (BCS) 3.5 were subjected to either ad libitum or restricted feeding for the 4 weeks before the expected start of calving (31 October) to create hinds of low (2.5) or high (3.5) BCS. The hinds were then grazed continuously on pasture of either low (<1200 kg DM/ha) or high (>2400 kg DM/ha) forage mass during lactation (29 October–25 March). In a 2 × 2 crossover design liveweight, liveweight gain and pasture intake were measured in both hinds and calves. Low hind body condition score (BCS 2.5) at the onset of lactation resulted in low calf weaning weight (46.9 kg) when forage mass was low, but not when forage mass was high (57.3 kg). High BCS (3.5) in hinds resulted in intermediate calf weaning weight when on low forage mass (51.2 kg) and high calf weaning weight when forage mass was high (56.6 kg). Both BCS and forage mass influenced calculated total milk production.
