Utilización de harina de yuca y soya integral cocida en dietas con dos formas de presentación para lechones de prelevante

Abstract

En lechones de prelevante (35 días 20kg) se evaluó al reemplazo de 50 y 100% del maíz por harina de yuca en combinación con torta de soya y soya integral cocida (SIC). Presentada en forma de harina y peletizada. En ensayo tuvo un arreglo factorial de 2 x 2 x 2 + 1 ,5 replicaciones. Las unidades experimentales o camadas estuvieron constituidas por lo menos por 6 lechones puros o cruzados de las razas Yorkshire, Landrace y Duroc. No hubo diferencias (P

In postweaning pigs (35 days, 20 kg) was evaluated the replacement 50 % and 100 % of corn by cassava meal, using soybean meal (SBM) and whole coocked soybean in a meal or pelleted diet. The experiment was conducte with a complete random design and a factorial arrangement 2 x 2 x 2 + 1 and 5 replications. Each experimental unit was constitutive for a Iitter with a minimum of 6 piglets, pure and (or) crossbred (Yorkshire, Duroc, Landrace). Diets were formulated to meet the nutrient requirements followed by NRC (1979), except energy requirements (3600 Kcal M.E. /kg). Were no differences (P and lt; 0.05) in feed consumption, weight gain, feed conversion and days to reach 20kg live wight in pigs due to the replacement of 50 % and 100 % of corn by cassava meal, there were differences(P
