Discounted profit for this breeding scheme was positive denoted with 35.92 € per animal due to a substantial reduction of breeding costs.
For the procreation of young bulls, breeding costs are additionally constrained.
Furthermore, genotyping bull dams was the major source of breeding costs, leading to values higher than 90% of the maximum possible breeding costs in the majority of parameter combinations.
The total cost of breeding schemes that maximised Δ Ga ranged from 544 685 to 718 973 € but only in 218 of the 975 parameter combinations was it below 700 000 €. Breeding costs incurred by genotyping females ranged from zero (no genotyping) to > 90% of the total breeding costs but was greater than 50% in 802 of the 975 parameter combinations.
Genomic selection might meet its promises concerning the increase in genetic gain per year, although the effects on breeding costs are still unclear.
Highly informative genetic markers may also allow breeders to combine simple, cost-effective mating designs (e.g., polymix or open-pollinated designs) with parental analysis to reduce breeding costs, speed breeding progress, and increase genetic gains [ 10, 11].
The breeding costs of path j were the sum over all expense factors in the path, and the total cost for a certain breeding program was the sum over all paths.
All told, the procedure cost about $10,000, said Joan Lacey, who paid the breeding costs and is listed as a co-breeder.
In consequence, profitability and furthermore sustainability of alternative breeding programs primarily depends on its applicability and corresponding breeding costs.
A breeding scheme based on the index trait BFiv measured on selection candidates implies low breeding costs, and simultaneously moderate genetic gain for meat quality traits.
