Pigmentación en pollos de engorde con la suplementación de harina de zapallo ( cucurbita maxima).

Abstract

The present investigation was established to evaluate the pigmentation in broilers with the supplementation of pumpkin flour (Cucurbita maxima), for which 80 experimental units arranged in a completely random design with 4 treatments were evaluated: (0%, 5%, 10% and 15% of pumpkin flour) with distinction of females and males, weekly weight gain, feed consumption, feed conversion, mortality, skin pigmentation and economic analysis were measured. The results show that there was significance in weight gain in Broiler chickens due to the supplementation of pumpkin flour (Cucurbita maxima), being T2 (Machos + 10%HZ) the best with 2322,73 grams with a feed conversion of 1,50. In addition, it was determined that skin pigmentation improved with T3 (Male + 15% HZ) with 6,20 and T3 (Female + 15% HZ) with 5,65 points, with values on the Roche scale. Finally, it was established that the treatment with the highest cost benefit ratio was T2 (Male + 10% HZ) with 1,59 and T2 (Females + 10% HZ) with 1,47 and a utility for males of 36,97% and females of 31,92%, so they are considered economically more profitable.
