The methods used to select farm animals for breeding

• Individual Selection: animals are selected basing on their performance or appearance (phenotype value)
• Progeny testing: selection is done basing on the performance of offspring of individual animals. For example, an animal to give birth to cow that produce a lot of milk
• Pedigree Selection: Here animals are selected basing on the performance of their ancestors. This method is used for traits that can’t be measured in life e.g. quality of beef. The breeder assumes that the animal considered will show the same characteristics as the ancestors.
• Family/Collateral relatives Selection: here is selection done basing on performance records of close relatives like brothers, sisters, half-brothers etc. The transmission of traits (characteristics) with known importance between relatives can be measured using subtests.
