Genetic correlations were estimated between first cross ewe reproduction traits and growth and carcass traits of their second cross lamb progeny. The 2460 crossbred ewes were progeny of 74 maternal breed sires and mainly Merino dams. The ewes had 3 j

The genetic variation of plasma IGF-I in crossbred ewe lambs postweaning was evaluated together with its potential use as a physiological marker for selection in meat sheep. Genetic variation for IGF-I was analyzed among 1,246 young crossbred ewes th

The reproduction of 2,846 crossbreed ewes with 7,899 records is reported. The ewes were progeny of mainly Merino dams and 91 sires from several maternal sire breeds including Border Leicester, East Friesian, Finnsheep, Coopworth, Corriedale, Booroola

Conformation scores can account for more than 20% of cattle price variation at Australian livestock sales. However, there are limited available references which define genetic factors relating objective live developmental traits to carcass compositio

Estimates of genetic and phenotypic parameters for lactation records of 143 ewes and growth performance of 134 Iambs were examined using the paternal half-sib mixed model analysis. Heritability (h 2 ) estimates for the curve parameters were 1.4, 0.3,

Growth and metabolic studies were conducted with 32 sheep (16 rams and 16 ewes) to evaluate Ficus leaves (Ficus thonningia) as substitute for Hyparrbenia rura (Hyparrhenia) in the diets ·'>f sheep. Ficus replaced O, 25, 50 and 75% of grass and was o

The accuracy of the gamma function to describe lactation curve of Yankasa ewes was investigated using milk production data obtained from 168 ewes with either complete or incomplete 84 day lactation records. Ewes were daily hand milked after over-nigh

The importance of direct genetic, maternal, heterosis and epistatic effects were examined on post-weaning weight, height, length, girth, fat depth and muscle (ratio of stifle to hip width) with dry and wet season gains in these traits. The breeds use

During a 5-yr period, 1994-1998, pre-weaning and weaning data were collected on 591 calves produced by mating either straightbred Jersey, straightbred Limousin or F1 (Limousin×Jersey) bulls to mature purebred Jersey or Limousin cows. Traits recorded
