Efecto de la ingestión de Chenopodium quinoa sobre el rendimiento productivo en ovinos y producción de gas in vitro
(2016) Cadena Yanchapaxi, Diego Rolando; Barros Rodríguez, Marcos Antonio
The aim of this research was to evaluate the effect of the ingestion of Chenopodium quinoa on the production performance in sheep and gas production in vitro. Eighteen sheep were used with an average weight of 21.34±2.03 kg. it is evaluated: 100% Kikuyo, kikuyo 80% + stover quinoa 20%, kikuyo60% + stover quinoa 40%. It was determined: voluntary intake, weight gain, feed conversion, in situ rumen degradability and digestibility MS and in vitro gas production. The results show differences in weight gain (P = 0.0001), showing higher gain the T2 (93.83g). The voluntary intake per Kg PV0.75 showed no significant difference (P= 0.1385) between treatments. Feed conversion was lower (P = 0.0178) in the T2 versus T1 (7: 1 to 9: 1 respectively). The apparent digestibility of DM did not differ (P = 0.2689) between treatments. The in vitro gas production (ml / 0.5 g fermentable MS) was 39 ml lower (P = 0.0215) in T2 with respect to T1. The ruminal degradation of DM for the soluble fraction A shows differences (P <0.05) between treatments, the largest percentage for T2, the fraction B showed differences for T1. It can be concluded that the stubble of quinoa can be included in the diet of sheep up to 20% improved productivity of the sheep.
