Determination of breeding goals and economic values of Adani goat in pasture system

Increasing the profitability of each production unit, is the most important way to increase its competitiveness in all fields, including animal husbandry. The first step in designing livestock breeding programs is to decide on appropriate breeding goals and the Lack of precise breeding goal determination is the most important factor behind the inadequacy of livestock breeding programs. Therefore, the determination of the breeding objectives and economic values of the important traits in the Adani goat, which is one of the important livestock of the Persian Gulf coastal strip, will greatly help the breeding of this animal.
In this study, a deterministic static model which assumes no variation among animals for the important traits was used for calculation of economic values. In order to estimate the required parameters (demographic, productive, reproductive, managerial, and economic), for a whole year of production (from the 1st of September 2016 to the 1st of September 2017), seven flocks of Adani goats with 920 does were directly recorded. The economic values of the traits were calculated by generating profit equations and changing the traits by one percent or one unit, while the mean of other traits was constant at the average of the population. The economic weight of the traits was calculated for a genetic standard deviation of the increase in the corresponding trait while the other traits were maintained at a constant average. In order to correct comparison the economic values of the traits, their relative importance was determined.
The results of this study showed that the highest income was the share of kid sales and milk and the largest share of the cost was the management and labor contribution. The traits that were included in the objective goals of the Adani goat including kidding rate, number of kidding per year, litter size, the weight of the kid sales at 12 months, conception rate, survival of the kid to weaning, doe survival, survival from weaning to sales, milk production, mature doe weight, and twining rate were 22.7, 17.5, 12.8, 12.1, 10.1, 9.8, 9, 4.6, 1.9, -0.7 and 0.3, respectively.
Reproduction, longevity and production traits are the most important trait in Adani goats, respectively. According to the breeding conditions of this animal, number of kidding per year, kidding rate, litter size, the weight of the kid sales at 12 months, conception rate, survival of the kid to weaning, doe survival, kid survival from weaning to sales and milk production are the most important traits, respectively and must be regarded more in breeding programs for Adani Goats.
