Phenomes: the current frontier in animal breeding

Software Packages in Animal Breeding

Six packages for solving mixed model equations and estimating variance components by REML are compared. Each has a unique strength. Meticulously finished DFREML is the only one that implements hypothesis testing for variance component estimates. MTDFREML is a comprehensive, relatively easy to install and simple to use package for analyses of experimental data. PEST, the only semi-commercial pro...

Random Regression in Animal Breeding

Precision animal breeding.

We accept that we are responsible for the quality of life of animals in our care. We accept that the activities of man affect all the living things with which we share this planet. But we are slow to realize that as a result we have a duty of care for all living things. That duty extends to the breeding of animals for which we are responsible. When animals are bred by man for a purpose, the aim...

Selection from Animal Breeding

The impact of genetics on animal breeding.

I F we would know how genetic knowledge is changing animal breeding practices or is likely soon to change them, we can probably get our best clues by asking what the animal breeders are studying now. Predictions made on this basis will not be wholly accurate, of course. The "endless frontier" nature of science precludes high accuracy in any method of predicting the future, especially the distan...
