Comportamiento productivo de ovinos mestizos Pelibuey suplementados con diferentes niveles de rechazo de Solanum tuberosum (papa) cocida más un aditivo buffer como estimulante ruminal

Abstract

The productive performance of mongrel sheep of the Pelibuey breed was evaluated at the San Pablo farm located in Chambo canton in Province Chimborazo at 2800 masl. Sixteen mestizo sheep with an average weight of 21.85 kg of similar age and phenotypic characteristics were used during 98 days of experimentation where a completely randomized block design was used, working with four treatments, in each treatment with four replications. For the development of this research, three levels (200, 300, 400 g) of cooked Solanum tuberosum (potato) plus buffer additive (50 g) were used in each treatment, to be compared with a control treatment (forage mixture). For the statistical analysis, the experimental results were subjected to an analysis of variance (ADEVA) and separation of means using the Tukey test at a significance level (P≤0.05), the productive behavior of the sheep during the research did not report significant differences in the parameters final weight and final height; while for the variables weight gain, feed conversion, carcass weight and carcass yield, favorable results were reported for the treatments that used cooked potato. It is concluded that 300 g of cooked potato plus buffer additive can be used because it improves weight gain by 17.9 kg, feed conversion 3.17, carcass weight 24.33 kg and carcass yield 63.4%, in comparison with the control treatment, in addition, no mortality is reported with its use. It is recommended to use cooked potato in other stages of sheep production, such as lactation and weaning, to prove the benefits of cooked potato in sheep production.
