Economic analysis of the Moghani sheep during the annual production cycle in two different cultivating systems
In this research, production, reproductive, managerial and economic characteristics of Moghani sheep breeding during the annual production cycle in nomadic and rural systems were used to identify the traits' performance and economic analysis of both rural and nomadic systems in Ardebil province. In order to estimate the economic value of the traits, the models that describe the production and reproductive conditions at the breeding ground of the sheep breed in the rural and nomadic system and the economic values of the traits were calculated using MATLAB software. The effect of increasing the unit of variation in average of attributes on the revenues and costs of production systems and the resulting economic value showed that in both systems, in the case of an increase in the average traits, the survival rate of the ewe, the pregnancy rate, the number of births per year, the weight of the wool and The weight of milk increases the income, and if the average weight of the alternative increases, it will increase the cost and eventually reduce the income. In nomadic and rural methods, the relative economic coefficients of all traits except the alternative weight trait were similar to those of most of the research carried out. Economic analysis of the system showed that in rural conditions, the income, expenses and profits per head of the ewe per year were 3864702.32, 3293308.57, 571393.75 Rials, in nomadic conditions of income, expenses and profit of the system, respectively, 8134659.38, 11072563.71 and 2937904.33 Rials. In order to investigate the effects of economic and biological variables on economic value, sensitivity analysis was performed. The cost-benefit analysis for each ewe's head was done in the Moghani sheep under the rural system, with the largest share of labor costs and the largest share of income related to the sales of live weight of lambs. While sheep in the nomadic system, the most was the cost of nutrition and the highest income associated with live weight during sales. Also, to study the changes in the factors affecting economic efficiency as a performance index, some of the parameters of the model were changed by 50 percent in the positive and negative directions. It was shown that if the traits change, the survival rate of the ewe, pregnancy rate and milk weight in the direction Positive increases the productivity index, but in the case of weight gain in the positive direction, it decreases productivity.
