Calf Rearing

Management deficiencies on the part of the pastoralists were claimed to be one of the major causes of the high losses of camel (Camelus dromedarius) calves contributing to low productivity of camel herds. In the present study, calf deaths, and the causes thereof, were analysed in connection with pastoral calf management in order to assess possible relationships. Progeny history data on 1506 Rendille, 789 Gabra and 1206 Somali calves born between 1980 and 1995 provided quantitative information on losses and the underlying causes. Assessment of the causes of death, and analysis of related management practices, led to suggestions for management changes. In feedback seminars with pastoralists, however, it became apparent that these management changes would not be adopted because they contradicted the pastoralists' assumptions on the causes of calf mortality. The discussions revealed that differences between pastoralists' and scientists' perceptions determined different opinions on proper calf-rearing management practices. Combining different knowledge systems offers the possibility of a more complete understanding, which is required for the derivation of adoptable calf mortality-reducing interventions that are compatible with the knowledge and production systems of the pastoralists.

Calf Rearing

AbstractA system of high-care calf rearing which was developed and demonstrated at the National Agricultural Centre Beef and Calf Unit is described. The unit reared around 600 calves per year which were purchased at 2 to 3 weeks of age, reared and then transferred to one of several finishing systems on the unit. The system depends on good calf nutrition, airy buildings which were rested regularly, careful disinfection of equipment and buildings and a programme of health management.The calves were purchased mostly in batches of about 40 from a farmers' co-operative and reared on milk replacer which was restricted and given twice daily to force a discipline for inspection of calves. They were also fed through teats which gave more efficient food conversion than buckets. They were penned in pairs because it had been found they were less stressed in pairs than penned singly. Detail of management and health routines are described. Target live-weight gains on the system were 0.5kg per day up to weaning and 1.0 kg per day thereafter. For simplicity the commercial names of foods, drugs and vaccines are given.

Calf Rearing

To wean calves early and then feed them dry meal, hay and water is thought to have a number of advantages over more conventional methods of calf rearing. These advantages include: a considerable saving of milk or milk substitutes, an early build-up of the microbial population of the rumen (thus permitting the use of simple inexpensive foods), and the saving of labour concomitant with early weaning.Accordingly, a number of small experiments were set up to test the practicability of early weaning, the effect of different dry feeds and of a variety of types of flooring for calf pens.

AbstractThe objectives of this study were (i) to characterise clinical health in dairy calves on an Irish research farm during the artificial calf-rearing period and (ii) to determine whether calves’ pre-weaning intakes and feeding behaviour, recorded by electronic calf feeders, changes in response to incidents of bovine respiratory disease (BRD). Holstein-Friesian (H-F) and Jersey (J) calves were fed by automatic milk replacer (MR) and concentrate feeders. Feeding behaviour, including MR consumption, drinking speed, number of rewarded and unrewarded visits to the feeder as well as concentrate consumption, was recorded by the feeders. A modified version of the Wisconsin calf health scoring criteria chart was used to score calves’ clinical measurements and identify incidences of BRD. Thus, 40% of calves were found to have at least one incident of BRD. Feeding behaviour was altered during incidents of BRD. The number of unrewarded visits to the feeder was reduced, by approximately four visits, for calves with BRD during the 3 d prior to the identification of BRD(P< 0.05) and tended to be reduced during the 7 d following the identification of BRD(P= 0.05), compared with healthy calves. Additionally, calves with BRD had a tendency for reduced net energy intake (approximately 8%) during the 3 d prior to the identification of BRD, compared with healthy calves. Therefore, calf feeding behavioural data, recorded by electronic feeders during the pre-weaning period, can indicate cases of BRD.
