Evaluación de la harina de suro en la alimentación de cuyes en la etapa de crecimiento y engorde.

Abstract

The objective of this research was to analyze the effect of using different levels of suro flour (Chusquea scandens) in the feeding of guinea pigs in the growth-fattening stage. Eigthy guinea pigs, 40 female and 40 male of improved genetics line of 15 days of age with an average weight of 0.46 kg were used for the different treatments, (5%; 10%; 15%) using sour flour in comparison to a control treatment. In this research a Completely Randomized Design (CRD) with 5 repetitions was applied. The size of the experimental unit (TUE) was of 2 animals. It was carried out at the Altamira Farm, Chilicay Campus, Cumandá Canton, Chimborazo Province. For the separation of media, the Tukey test was used. Highly significant differences were recorded (P <0.01). The treatment T2 (10% of sour flour) which obtained the best results in the variables final weight 1.22 kg, weight gain 0.77 kg, consumption of concentrate based on dry 2.46 kg, total feed consumption 4.95 kg, feed conversion 6.51 kg carcass weight 0.87 kg. While when evaluating the productive behavior of the guinea pigs of the sex factor, highly significant differences were registered in the variables, consumption of concentrate, 2.42 kg, consumption of forage 2.50 kg, and total food consumption 4.91 kg. The males showed to be those with the best values. When analyzing the cost benefit variable, it was higher in Q2 (10%) and Q3 (15%), which reached a value of 1.15 USD, that is, for every dollar invested, there was a profit of 15 cents. It is recommended to use up to 15% of sour flour, as the highest cost benefit is recorded and the supply of this raw material does not affect the biological behavior of these livestock.
