Inbreeding depression in Zebu cattle traits.
The productivity of herds may be negatively affected by inbreeding depression, and it is important to know how intense is this effect on the livestock performance. We performed a comprehensive analysis involving five Zebu breeds reared in Brazil to estimate inbreeding depression in productive and reproductive traits. Inbreeding depression was estimated for 13 traits by including the individual ...

متن کاملPreweaning growth rate and weaning traits of Angus, zebu and zebu-cross cattle.
A 4-yr study was conducted on the preweaning growth rate and weaning traits of 620 calves from: (1) Angus (A), Brahman (B), Brangus (BR) and Africander-Angus (AF) dams sired by A and B bulls; (2) BR dams mated to BR sires and (3) AF dams mated to AF sires. Heifers were placed in the breeding pastures as 2-yr-olds and exposed to bulls for 75 d. Breed groups differed (P less than .01) in weaning ...
متن کاملProduction traits of Holstein cattle: estimation of nonadditive genetic variance components and inbreeding depression.
Additive, dominance, and additive by additive components of genetic variance and inbreeding depression were estimated for production traits from a group of daughters of young sires from the Canadian Holstein population. First lactations of 92,838 cows were analyzed. Three sire and dam models (additive, additive plus dominance, additive plus dominance plus additive by additive genetic effects), ...
متن کاملInbreeding in Dairy Cattle
Inbreeding is defined as half of the genetic relationship between an animal’s parents. For example, the offspring from a mating of animals A and B, which have the same father, will have 12.5 percent inbreeding, because the genetic relationship between A and B is 25 percent. Statistical methods to select the best sires of each generation have been developed, making it feasible to achieve any pos...
