Production Characteristics

Production and management characteristics of an open range shorthorn beef cattle herd were recorded for a four year period on a cattle station in the south-east Pilbara region of Western Australia. Herd numbers increased from 893 to 1538 resulting in a 72% increase in grazing pressure on the grazeable portion of the lease. Branding rates varied from 54 to 78% of the cows present for mating the previous year. Mortality rates increased from 4% in 1974 to 15% in 1976. Losses anlong cows older than six years and female calves were significantly higher than among animals in other age and sex categories. Turnoff during this period of herd build-up varied from 3 to 11% of the herd.

Selection Of

Estimates of (co)variance components and genetic parameters were obtained for a preweaning weight, recorded between 2 and 5 months after birth, and the subsequent gain till weaning for two herds in a selection experiment in Western Australia. Analyses were carried out both accounting for age at weighing and assuming birth dates and thus ages were unknown. On adjusting for the interval between weighings, preweaning gain appeared to be independent of age and equally heritable to weaning weight. Estimates of the direct genetic correlation between preweaning gain and weaning weight (adjusted for age) were 0.9 or higher, while both genetic and permanent environmental maternal correlations were close to unity. Implications for the use of preweaning weight as an alternative selection criterion to weaning weight when birth dates are not recorded are discussed.
