“…Prepubertal female lambs have a period of accelerated mammary parenchymal growth ending at about 4 months of age (Anderson 1975). During that critical period, high level of nutrition may inhibit the mammary parenchymal growth and reduce milk yield of ruminants at maturity (Gould and Whiteman 1975, Johnsson and Hart 1985, Foldager and Sejrsen 1991. Also too low level of nutrition before mating has had a negative effect on the productivity of ewes (Kassem et al 1989).…”

The effect of different feeding levels on the performance of primiparous ewes was studied in 31 Finnish Landrace ewes bred to lamb at the age of one year. Ewe lambs, initially weighing on average 19.2 kg (SEM 0.63), were placed on a low (L), standard (S) or high (H) level of feeding from 2 months of age to the end of mating and from 2 months pre-partum to the end of 8-week lactation. Changes in live weight were affected by the diet. During rearing, the ewe lambs on L diet gained significantly less (18.0 vs. 24.1 kg/lamb, P
