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.

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.

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.

Crossbreeding and Meat Quality in Pigs

1987
A review is presented on heterosis for meat quality. The classical view, i.e. no significant heterosis, is to be revised to some extent when considering specific meat quality traits in specific crosses. Evidence is presented for two main deviations from additive inheritance of breed differences in crossing.

"Crossbreeding" Geographical Quantities

Geographical Review, 1955
A s INCONCEIVABLE as a "boneless vertebrate" is a "nonquantitative geography." Estimates and measurements of terrestrial magnitudes-distances, directions, dimensions-have always constituted the framework of geographical knowledge. There are, however, degrees and standards of "quantitivity." Those attained by Eratosthenes and Ptolemy were comparatively ...
