Parachlamydia involvement in bovine abortions in a beef herd in Scotland

Massey University assumed management responsibility for "Riverside", a 723 ha sheep and beef cattle farm 8 km north of Masterton in Master-ton in March 1978. The farm is leased to the University under the terms of the will of the late Mr Sydney Campbell to assist in the accumulation, expansion and dissemination of knowledge about agriculture, with particular emphasis on agriculture in the Wairarapa. A lo-year farm development programme instigated in 1978 resulted in the sale of the beef herd and the winter stocking rate of sheep being increased to 15.1 suiha by 1984 (9.7 sulha in 1978). In 1985 stocking rates were sharply reduced following a severe drought and the current mixed 2-year bull beef and breeding ewe policy was introduced. Recent research has focused on drought-tolerant pasture species. In late 1992 sheep and beef cattle farmers (n=lOO) were surveyed to identify local information needs and how Riverside could continue to serve the region's research and extension requirements. Information related to fertilisers and farm management were most frequently rated as the most imporant current needs. Keywords: extension, research, Riverside, teaching, Wairarapa

Analysis Of Performance

The need to speed up the rate of genetic progress in beef cattle, particularly in economically significant traits such as growth and carcase merit has always been recognised by the Meat and Livestock Commission. This is achieved through the Beefbreeder Pedigree Recording Service which records over 1,000 pedigree herds in Great Britain. Traditionally, analysis of performance records from pedigree herds has been carried out using within herd contemporary comparisons.Average pedigree beef herd size in Great Britain is typically less than 20 cows which limits accuracy and scope for genetic improvement when making within herd selection decisions.

The One

Epitheliogenesis imperfecta (EI) has been diagnosed in calves on a north Queensland beef cattle research station. There are five Bos indicus cross, inter se mated breed groups on the station: 1/2 Brahman, 3/4 Brahman, 1/2 Sahiwal, 3/4 Sahiwal and High Grade Sahiwal. The disease was confined to the three Sahiwal breed groups and caused calf losses over seven years from 1978 of 0.2%, 3.4% and 1.0% in the 1/2, 3/4 and High Grade groups respectively. The Sahiwal breed was identified as the origin of the gene responsible for the disease. The source of the gene within the Sahiwal breed was investigated, and several ancestors were identified as almost certainly being heterozygotes. Analyses of relationships of affected and non-affected calves to the 10 Sahiwals that were originally imported into Australia identified the one that was most likely the source of the El gene.

Running a Small Beef Herd provides an introduction to beef production for those about to enter the industry and is an ongoing reference for anyone managing a small herd of beef cattle on their property. Fundamental considerations such as the economics of beef production, the selection of a suitable beef enterprise to match a particular property and level of experience are covered. It considers various systems suitable for a small beef operation: steer fattening, cow and calf systems, foster calves and multiple suckling, and lot feeding. Running a Small Beef Herd offers practical advice on buying cattle, marketing methods for particular types of cattle and specifications for markets. Cattle handling, necessary husbandry practices such as castration and vaccination, herd health, reproductive management, nutrition and carrying capacity are also explored. This updated edition expands on the systems of beef production, breeds, breed management, supplementary feeding, drought management, ear tagging requirements and soil health and fertility.

Over Time

This paper quantifies the benefits of using a sire genotyped for a single recessive gene in a commercial beef herd. A modified gene-flow method was used to account for changing allele frequency over time. The benefits to a commercial breeder of using a genotyped sire were highest when initial allele frequency was moderate and when the sire was used in a self-replacing herd that had increased allele frequency over time. An example of the thyroglobulin gene affecting marbling in beef cattle was used. The value to a self-replacing herd of a sire homozygous for the favourable allele of the thyroglobulin gene was shown to be up to $338 more than of an ungenotyped sire, in a population where the initial gene frequency was 0.3 and the genotype accounted for 0.5 standard deviations of phenotypic variation.
