I understand line breeding.cbcr":1l1sc9d9 said:I have another question. When making the choice on a bull for crosbreeding would you get more hybred vigor using a line bred bull on line bred cows? And then what would be the effect of crossing non related progeny?
Linebreeding is a form of inbreeding in which an attempt is made to concentrate the inheritance of some favored ancestor in descendants within a herd. The average relationship of the individuals in the herd to this ancestor is increased by linebreeding, but at the cost of an increased level of inbreeding.
While a linebred animal can be important in the creation of a composite animal. As in the difinition above a linebred animal is bred for certain desirable trait(s) and with the breeding concentration it is expected that that trait is above average for consistency.
But in the case of (Composite, Hybrid, Crossbred) animals hybrid vigor is much higher when unrelated animals are mated.
I don't know if you answered the question. I may have asked it wrong.
I am talking of crossing 2 line bred animals of different breeds. Bos Indicus X Bos Taurus. Would there be an increase because they are linebred.
