AbstractA method is described for assigning beef cattle performance records to within-herd management effects (contemporary groups) retrospectively, using information on the recording date and herd. This method takes account of the within-herd calving pattern. The objective of developing a method of assigning records to contemporary groups was to maximize the contemporary group size while ensuring as far as possible that records in any contemporary group were subject to the same management.A simple method for assessing the effectiveness of different strategies for assigning records to contemporary groups is proposed, based on investigating the balance between the effects of contemporary group size upon the heritability and the accuracy of mass selection.The results of a study of different contemporary grouping strategies in the Simmental breed are reported.

Cattle Performance

A comprehensive review of the impact of tropical pasture grazing, nutritional supplementation during feedlot finishing and fat metabolism-related genes on beef cattle performance and meat-eating traits is presented. Grazing beef cattle on low quality tropical forages with less than 5.6% crude protein, 10% soluble starches and 55% digestibility experience liveweight loss. However, backgrounding beef cattle on high quality leguminous forages and feedlot finishing on high-energy diets increase meat flavour, tenderness and juiciness due to improved intramuscular fat deposition and enhanced mono- and polyunsaturated fatty acids. This paper also reviews the roles of stearoyl-CoA desaturase, fatty acid binding protein 4 and fatty acid synthase genes and correlations with meat traits. The review argues that backgrounding of beef cattle on Desmanthus, an environmentally well-adapted and vigorous tropical legume that can persistently survive under harsh tropical and subtropical conditions, has the potential to improve animal performance. It also identifies existing knowledge gaps and research opportunities in nutrition-genetics interactions aimed at a greater understanding of grazing nutrition, feedlot finishing performance, and carcass traits of northern Australian tropical beef cattle to enable red meat industry players to work on marbling, juiciness, tenderness and overall meat-eating characteristics.

Progeny Group

A numerical procedure was utilized to optimize the number of progeny for young bulls and reference sires in a beef sire progeny testing program. Optimization was based on attaining a desired level of accuracy on the types of comparisons that were to be made after the test was completed. As heritability increased, the total number of progeny required decreased, but the percentage of reference sire progeny remained the same. There were near optimum progeny distributions with smaller total number of progeny and only slightly less accurate than the optimum solutions which could also be considered for application. Key words: Progeny testing, beef cattle, optimum designs, reference sires
