Age at First Mating on Lifetime productivity of Corriedale Ewes in Southern Brazil. Repositório Alice
OLIVEIRA, M.M. de; KENNEDY, J.P.; SELAIVE-VILLARROEL, A.B..
A total of five different Corriedale flocks (respectively initiated in years 1976--1980), totalling 2,561 breeding ewes, were first mated at 19-20 or 30-31 months of age. Lifetime production data on: a) fleece weight and its components (as measured by greasy fleece weight, washing yield, clean fleece weight, fibre diameter and staple length), b) reproductive performance (as evaluated by the number of lambs weaned/ewe joined and lamb weaning weight/ewe joined) and c) ewe liveweight, were investigated within each flock up to 1982. Considering the environment provided in the study, the results indicated that earlier mating in these Corriedale ewes depressed their subsequent wool quantity, yet there was no appreciable effect upon wool quality components and...

Joining Time and Stocking Rate on the Production of Corriedale and Romney Sheep Lambing on Winter Improved Pasture in Southern Brazil. Repositório Alice
OLIVEIRA, N.M. de; KENNEDY,J.P.; SELAIVE-VILLARROEL, A.B..
Wool weight, fleece components and reproductive performance of Corriedale and Romney sheep joined within three periods (14 january-25 february, 01 march-12 april and 15 april-27 may) and stocked at two rates (10 ewes/ha and 15 ewes/ha) on paddocks of winter improved pasture (Trifolium repens and Lolium multiflorum) up to weaning, were examined during 5 years (1977-1981) at EMBRAPA, Bage, RS, Brazil. In the environment employed, the results were consistent in showing that Corriedales were superior to Romneys either in wool quantity and quality or in reproductive performance, and indicated that when 10 or 15 ewes are stocked per hectare, the higher stocking rate did not cause any harmful effect on both wool or reproductive components. Fleeces produced from...
