    (2022-09) López Gutiérrez, Mijael Alexander; Rosero Peñaherrera, Marco Antonio
    The research work was carried out in the Chiquicha parish of Pelileo canton, Tungurahua province, located at 2598 meters above sea level at 1°16'0'' south latitude and 78°31'60'' west longitude. The objective was to evaluate the anticoccidial effect of alfalfa saponin (Medicago sativa L) included in the diet of broilers, a completely randomized design (DCA) was applied with 4 treatments: T1 (10 g of alfalfa saponin extract /40 kg of feed), T2 (20 g of saponin extract from alfalfa/40 kg of feed), T3 (30 g of saponin extract from alfalfa/40 kg of feed) and T4 (0 g of saponin extract from alfalfa). alfalfa/40 kg of food) with 3 repetitions. The results obtained were for the variable number of oocysts/g of feces, on day 19 (5 post inoculation) and 21 (7 post inoculation) being the best T (10 - S), T (20 - S) and T (30 –S) with a mean of 0.00 ooq/g, on day 23 (9 post inoculation) the best treatment was T (30 - S) with a value of 50.00 ooq/g. On day 25 (11 post inoculation) the best result is presented by treatment T (20 – S) with a value of 166.67 ooq/g, for day 27 (13 post inoculation) the best result was obtained in T (30 – S) with a value of 333.33 ooq/g, on day 35 (21 post inoculation) the value of 1450.00 ooq/g was for treatment T (30 - S), on day 42 (28 post inoculation) and 49 (35 post inoculation) the same behavior was presented as in the previous days, obtaining a value of 25626.67 ooq/g and 104150.00 ooq/g respectively. Finally, on day 56 (42 post inoculation) the best result was T (30 – S) with 107416.67 ooq/g, while the treatment that presented the highest number of oocysts in the investigation is (T – 0). On the other hand, the productive indices such as: live weight, feed conversion and European index were better in the birds fed with alfalfa saponin extract, while weight gain was better in the treatment that did not include the saponin extract in its feed. diet.
