Abstract

The recovery of degraded areas, the reduction of production costs and intensive use of the area throughout the year, are being made possible by cereals intercrop with forage. Despite of the sheep production systems have shown a considerable growth in recent years, the inclusion this animal species in crop-livestock integration systems is still small, requiring further studies. The research is composed of two sequential experiments conducted during two years on Botucatu city, São Paulo State. The experimental design of first experiment will be randomized blocks, with four replications, in factorial scheme 3x2, being three cultivation modalities of corn crop for silage (exclusively, in intercrop with Brachiaria brizantha cv. Marandu and Brachiaria brizantha cv. Piatã in the sowing row) and two silage harvest heights (20 and 45 cm in relation to the soil surface) with grain in stage 1/4 milk line. The experimental design of second experiment will be in split-plot scheme. The treatments of first experiment constitute the plots and the absence or over seeded of oat cultivar São Carlos (Avena bysantina) after the silage harvest constitute the sub-plots. The experimental unit is the subplot (piquet) which will be allocated three crossbred male lambs Dorper x Santa Inês, with average initial weight of 23 kg and average initial age of 90 days, totaling 144 animals. The grazing method is the continuous stocking with stocking rate fixed, and the animals will be supplemented with the silage the same treatment + multiple mineral supplement. Will be evaluated the silage, the pasture, the straw decomposition and the soil physical/chemical attributes, as well as, the performance, the ingestivo behavior and the carcass characteristics of lambs. Data will be analyzed for distribution normality and the results submitted to variance analysis by test F (P<0.05). Data of straw decomposition will be adjusted by regression analysis (orthogonal polynomials) in function of days, adopting the equation with highest determination coefficient (r2) (P<0.05). Other data will be compared by Tukey test (P<0.05). (AU)
