Index Selection In Terminal Sires Improves Early Lamb Growth, G. C. Márquez, W. Haresign, M. H. Davies, G. C. Emmans, Rainer Roehe, L Bünger, G. Simm, Ronald M. Lewis

Department of Animal Science: Faculty Publications

The use of terminal sires (TS) for crossbreeding is integral to the UK sheep industry where approximately 71% of market lambs are sired by TS rams. Early growth of these crossbred lambs affects profitability. The objectives of this study were i) to evaluate the effectiveness of index selection among TS on BW and ADG of their crossbred offspring; and ii) to compare the efficacy of that selection within TS breeds. The most widely used TS breeds in the United Kingdom are Charollais, Suffolk, and Texel. These participated in sire referencing schemes in which they were evaluated on a lean growth …

Genetic Relationship Between Longevity And Objectively Or Subjectively Assessed Performance Traits In Sheep Using Linear Censored Models, W. Mekkaway, Rainer Roehe, Ronald M. Lewis, M. H. Davies, L. Bünger, G. Simm, W. Haresign

Department of Animal Science: Faculty Publications

Genetic parameters of longevity in crossbred mule ewes, and genetic relationships among longevity, growth, body composition, and subjectively assessed traits on mule lambs and ewes have been estimated using Bayesian linear censored models. Additionally, the genetic associations between longevity and culling reasons were examined. Data comprised 1,797 observations of mule ewes for longevity, culling reasons, growth, body composition, mouth scores, and type traits. Longevity was defined as the time (in years) from 2 yr of age (the age at first lambing of most ewes) to culling or death. Censored data (i.e., observations for which only the lower bound of the …

Special Field Days For Merino Breeders, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

More than 200 Merino stud breeders attended special stud breeding and fertility field days arranged for them by the Department of Agriculture recently.

Breeders attending represented some 40 per cent of the State's Merino studs.

Twinning Increases Production, K P. Croker

Journal of the Department of Agriculture, Western Australia, Series 4

Many breeders claim that twinning causes too many losses among Merino lambs and does not favour breeding for twin lamb production.

But recent experiments have proved otherwise and agricultural scientists now agree that . . .

TWINNING INCREASES PRODUCTION

THE low marking percentages regularly recorded for Merino flocks suggest that the Merino is a relatively infertile breed.

Certainly, lambing percentages are low when compared with those of most British breeds of sheep.
