Animal Breeding And Selection
Certain value economic weight is assigned to each trait depending its h2 and economic value as well as genetic correlation among the traits.
. Selection for heterosis-results with laboratory and domestic animal. Concerned with the production and care of domestic animals. 2 The performance records for milk and other maternal qualities are available only after sexual maturity is reached.
Selective Breeding of animals only. 3 When the heritability of a trait is high individual merit is a poor indicator of breeding value. Deer Some animals lack a well defined dominance hierarchy Eg Bighorn sheep For an animal to be of benefit to humans it needs to grow fast.
Technique that uses genes to treat or prevent disease. Cats Some animals are territorial during breeding seasons when they fight and dont tolerate each other Eg. Save the eggs of the best egg laying hen for hatching.

One method Burbank used was hybridization crossing dissimilar individuals to bring together the best of both organisms. The intentional mating of two animals or plants.
Collected semen deposited directly in to females. Animals are ranked on the basis of the estimated breeding values EBV and the better animals are mated together and the rest are culled ie. Seeds from the largest heads of grain.

The next events might occur when information is available on animals themselves and maybe also on sibs. Identify desirable characteristics Choose parents w these characteristics Select the best offspring from parents to breed the next generation Repeat 1-3 continuously Domestic Animals Selective Breeding of Horses Horses were first domesticated. Hybridsthe individuals produced by such crossesare often hardier than either of the parents.
In animal breeding genetics and biotechnology for over 37 years. Animal breeders analyze the data to estimate the breeding values of individual animals in a population using statistical linear models. Selective Breeding-selected organisms bred with one another to produce offspring with desired traits.
Deficiency in some traits is taken into account by superiority of other traits. Proceedings of II the World Congress on Genetics Applied to Livestock Production. The first selection event might be based entirely on pedigree information usually the average of the parents breeding values.
Function of the male. American botanist Luther Burbank developed more than 800 varieties of plants using selective breeding methods. I To predict the BV of individuals ie û based on their own records and or their relatives records.
The book covers the discipline of animal breeding from. This is sometimes called stepwise selection. Ii To predict the environmental effect common to all records of an animal ie pˆi the permanent environmental effect of animal i.
Selection within a population is usually applied in several stages. Learn faster with spaced repetition. Two Main Types of Breeding.
Seeds from the juiciest berries. Selection index is an index of the net merit of an animal for many traits. Produces offspring with desirable traits.
