Avaliação econômica de diferentes técnicas de inseminação artificial em ovinos da raça Santa Inês - DOI:10.5039/agraria.v4i2a16

Abstract

This study aimed to determine the cost of lamb produced from different artificial insemination te chniques in Santa Ines sheep. The experiment was conducted on a 3 x 2 factorial arrangement, on a randomized block design. One hundred and two females were divided in three groups: cervical artificial insemination with fresh semen - AI or frozen-thawed semen - AIFT or laparoscopic artificial insemination - LAI. On the determination of the total cost of the produced lamb, variable and fixed costs were considered. The costs from the labor suffered a great technical variation among the techniques as 9.4% in IAC, 17.7% in IAF e 26.4% in IAL. The expenses with hormonal treatment were higher when compared to other components corresponding to 65.8, 54.0 and 28.7% to IAF, AIFT and LAI, respectively. The total cost of the lamb changed according to the artificial insemination technique used, as the IAF cost was 4.4 times lower than IAC cost and 2.2 times lower than IAL cost. The IAF presents lower cost per produced lamb when compared to the other techniques. The IAC, due to low fertility rates achieved, was economically unfeasible, while the IA by laparoscopy, in spite of the satisfactory fertility rate, contributes to increase the cost of lamb produced.
