13. fixed resources Size of the farm
Ability to grow supplementary feeds
Available labor
14. Management Policies implemented by the farmer — feeding, healthcare, length of time an
animal is on the farm
15. Economics Costs of farm inputs like feed, labor, and supplies and the prices of farm outputs.
16. Traits Observable or measurable characteristic of an animal
17. Phenotype Observed category or measured level of performance for a trait in an individual
18. environmental ef- Effects that external factors have on animal performance
fects
19. Biological Type a classification for animals with similar genotypes for traits of interest
20. interaction a relationship in which the effect of one factor depends on another factor
21. Genotype by En- A dependent relationship between genotypes and environments in which the
vironment (G x E) difference in performance between two (or more) genotypes changes from en-
Interaction vironment to environment
22. Genetically animals have evolved in that location over many generations and carry the genes
adapted that allow them to survive and thrive in those locations
23. Breeding Objec- a general goal for a breeding program - a notion of what constitutes the best
tive animal
24. Seedstock breeding stock, animals whose role is to be a parent or, in other words, to
contribute genes to the next generation
