Evaluación de la Fertilidad de la Cipermetrina Deltametrina, Fipronil, Triclorfón como Antiparasitarios Externos en Cuyes

Abstract

In the Program of Minor Species of the Faculty of Sciences of the ESPOCH, was evaluated the effectiveness of different external parasitic (cypermethrin, deltamethrin, fipronil, trichlorfon), for control of ectoparasites (lice) as well as its effect on growth performance of guinea pigs in the stage of growth - fattening, using 20 experimental units of four weaned guinea pigs each one of them, the experimental results were submitted to an analysis of variance and separation of averages during the test of Tukey. Determining the application of cypermethrin, effectiveness from 96.67 % to 45 days and 100% to 60 days, not in this way with the trichlorfon that to 45 days was 51.84% and to 60 days and 90.73%, but to 70 days the guinea pigs were free of ectoparasites. To the worming to the guinea pigs with cypermethrin showed better answers in the productive end weights (1.11 kg), increments of weight (0.83 kg), feed conversion (5.76), weights and yields to the channel (0.83 kg and 74.71%, respectively), and the increased economic efficiency (B / C of 1.22), difference in employment of trichlorfon, that productive presented lower rates and lower profitability (8%), for what recommended that you use cypermethrin for the control of ectoparasites of guinea pigs.
