Designing genetic impact assessment for crossbreeding with exotic beef breeds in mixed farming systems

, 2021
A genetic impact assessment (GIA) methodology is developed, consisting of consultation of stakeholders, identification of issues and assessment of associated indicators, for crossbreeding with exotic beef breeds in smallholder mixed farms.

Efficient design of crossbreeding experiments

Theoretical and Applied Genetics, 1989
The efficiencies of different experimental configurations for estimating additive (A) and heterotic (H) effects in purebred and crossbred populations derived from two parent breeds are examined. Allocation of resources over six groups is considered: the two parental breeds, the F1, the F2 and the backcrosses to the two parental breeds.

Dairy cattle crossbreeding in the tropics: Choice of crossbreeding strategy

Tropical Animal Health and Production, 1996
Two strategies for crossbreeding of indigenous and exotic cattle for milk production in the tropics, viz. rotational crossing and formation of a composite breed, have been compared. Genetic considerations suggest that rotational crossing would lead to somewhat better dairy performance, mainly because of more heterozygosity.

The basis of crossbreeding in pigs; A review

Livestock Production Science, 1976
Abstract A survey of the different parameters involved in crossbreeding is given following the analysis of Dickerson (1969). The genetic gain resulting from crossbreeding has a double origin: complementarity and heterosis. The practical importance of these two advantages is evaluated in swine.
