Utilización de subprodcutos de cosecha para la alimentación de cuyes en la etapa de crecimiento y engorde

Abstract

The objective of this research was to evaluate the effect of harvest by-products in the feeding of guinea pigs during the growth and fattening stages. Composed of different treatments: T1(carrot+oats+corn leaf+concentrate), T2 (carrot+corn leaf+concentrate), T3 (oats+corn leaf+concentrate), T4 (oats+carrot+concentrate) versus a control treatment. A total of 60 animals (30 females, 30 males) of 15 days of age, with an average initial weight of 352 g, were used. A completely randomized design was used in a combinatorial arrangement of factors: factor A corresponded to the feed rations and factor B to the sex of the animals. The results obtained were subjected to an analysis of variance (ADEVA) and a separation of means according to Tukey (P≤0,05). When evaluating the productive parameters of final weight and weight gain according to T1, results of 1259 g and 903.83 g were obtained, respectively, as well as the productive parameters of feed conversion and carcass yield %, with no significant differences (P>0.05). However, the highest values were observed in the guinea pigs that were in T1 for carcass yield with 67,38% and T2 for feed conversion with 5,45. It was concluded that the best treatment T1 (carrot+oats+corn leaf+concentrate) in the feeding of the guinea pigs was evidenced in the good body development of the guinea pigs. It is recommended to carry out research in which new crop by-products (beans, peas, beans and broccoli) can be used in different species of zootechnical interest, such as rabbits and sheep.
