Evaluación de diferentes niveles de harina de yuca de rechazo en la alimentación de cuyes durante la etapa de crecimiento - engorde

Abstract

In the present investigation, the impact of the different levels of rejection meal on the feeding of guinea pigs of the improved line during the growth-fattening stage was evaluated over period of 75 days. The experimental units consisted of a total of 64 guinea pigs, 32 females and 32 males. A completely randomized design was applied, in a combinatorial arrangement of factors, where factor A was the levels of rejection cassava meal, and factor B was the sex, working with 4 repetitions and an experimental unit size of 2 animals. The treatments evaluated were: T1 (10%), T2 (20%), T3 (30%) of cassava rejection meal for comparison with the control treatment. To verify the results, an analysis of variance (ADEVA) was performed, separating the means of the treatments according to Tukey's test at a significance level (P<0.05), resulting in highly significant differences in the feed conversion variable, while for the rest of the variables we found significant differences. It is concluded that the best treatment was T1, because it contributes to improve the feed conversion rates without affecting the productive behavior of the cattle, showing that the males obtained the highest yields, with a final weight of 0.95 kg, a weight gain of 0.64 kg. Finally, it is recommended to use 30% of rejected cassava meal with a benefit/coast of 1.20, which represents that for each dollar invested, there is a profitability of 0.20.
