From a genetic point of view, the selection of breeds and animals within breeds for conservation in a national gene pool can be based on a maximum diversity strategy. This implies that priority is given to conservation of breeds and animals that dive

SummaryThis paper addresses major issues and challenges for Animal Genetic Resources (AnGR) and the livestock sector, as well as options for further development of policies or regulatory approaches. Three main areas were identified, i) how we can hal

SummaryCross-breeding with European beef breeds has become a standard approach for the intensification of smallholder cattle production in Indonesia. This study assessed the environmental impact of cross-breeding, in terms of Global Warming Potential

The objective of this study was to estimate genetic correlations among fertility and measures of energy balance, dry matter intake, and live weight (change). Data from 622 first lactation cows (fed ad libitum a complete ration) included milk, fat, an

In Indonesia, cross-breeding local cattle with European beef breeds is widely promoted to stimulate beef production. This cross-breeding is threatening local breeds that have often different functions, including cultural roles. This study analysed th

A closed nucleus breeding program for beef cattle, to increase beef production from the dairy herd, was studied. The nucleus will produce purebred beef embryos for implantation into dairy cows. The breeding goal was an acceptable level of dystocia an

Jersey, Friesian (Fr) and Dutch Red and White (DRW) dairy cows were treated over three lactations with BST, recombinantly derived bovine somatotropin (somidobove), in a sustained-delivery vehicle injected subcutaneously once every 28 days. In the fir

A field trial was conducted to determine genetic parameters in veal and beef production, relationships between performance test and progeny test, and effects of performance and progeny testing on the returns from selection. Progeny of 61 performance-
