Crossbreeding is probably the most misunderstood and underappreciated practice in commercial livestock production. Crossbreeding is the mating of males and females of different breeds or breed types. Purebreeding is the mating of individuals of the same breed or type.
Crossbreeding is the recommended breeding strategy for commercial meat sheep and meat goat production.
As a breeding practice, crossbreeding does not denote the indiscriminate mixing of breeds. Rather, it is the systematic use of breed resources to produce offspring of a specific type.
crossbreeding program uses a male of superior growth to produce lambs or kids for market, while maintaining moderate sized females that excel in fitness and reproductive performance.
Crossbred lambs and kids grow faster and have higher survivability than their purebred counterparts. Crossbred GOATS are more fertile.
Breed complementarity is the other major advantage of crossbreeding. It relates to the fact that there are no perfect breeds.
Each breed possesses certain strengths and weaknesses.
In a systematic crossbreeding program, breed resources are combined to balance the positive and negative aspects of each breed in the cross.
For crossbreeding to be most effective, it is important to identify the strengths and weaknesses of different breeds and to determine the appropriate role of a breed in a crossbreeding program.
Cross-breeding larger with smaller breeds achieved faster growth rates in the progeny.
CROSS BREEDING AND SELECTION OF GOATS:
Environmental factors include nutrition, age of mother, rearing status and birth date. select animals based on their performance.
It is not likely the selection group will all be early born, single kids. However, some of the later born twins, although they do not look as good.
All animals get half their genes from each parent. The genes passed onto each offspring are randomly selected.
When you are selecting animals for breeding, the aim is to select the ones which will pass on good genes to their offspring.
The reason for this is that the selected parents were good partly because they had better genes but partly because they had a better environment.
select animals that are both good for genes and good for environment. However, they will only pass onto their offspring, the superiority of their genes. They will not pass on their superiority in the environment
