摘要: At the Mirador farm of Patricia Pilar Parish km 41 on way Santo Domingo Quevedo, located in Buena Fe Canton, Los Rios Province, three levels silo banana were evaluated 5-7-yr crossbred Sahiwal cows at second third lactation (8, 12, and 16 kg/animal/day) compared to a control treatment (forage feeding) through completely random block design (DBCA) evaluating different productive features over the120 days investigation. Statistical differences (P<0.05) between treatments established, showing that best level silage surplus use was kg with higher weight gain milk production animals supplemented this 18.50 13.54 l milk/cow/day production. On other hand lowest response obtained group 14.75 8.28 The benefit-cost index upon using reaching an 1.12 USD while only 1.10 determined. This is why it recommended kg/animal/day as has shown efficiency improving considerably economic yields. LISTA DE CUADROS No. Pag. 1. DIGESTIBILIDAD LA BANANA. 14 2.
