Conteúdo: | Abstract: Sixty-six Awassi ewes were divided into two equal groups. The sheep were milked twice daily from lambing for 22 weeks. In one group (weaned) the lambs were separated from their dams within 6 h of parturition. In the second group (suckling) the lambs sucked the residual milk after milking for 15 weeks, after which they were weaned. Milking yields, fat tests, lactational persistency and udder health were not affected by the early weaning. The suckling ewes had greater amounts of residual milk and consumed more concentrates. Further data are presented that suggest that there may be a critical period of attachment of at least 10 days following lambing, during which weaning may effect subsequent milk production. The practical implications of these results are discussed in terms of flock management and the intensification of breeding programmes.
