Abstract

This research will be composed of two sequential experiments conducted in Botucatu, São Paulo State, Brazil. The aim will be to validate an integrated crop-livestock system to production of corn silage, with alternatives for subsequent pasture formation, aiming at finishing lambs in semi-feedlot. The experimental design of the first experiment will be a randomized block, with 24 replications, being two modes of corn cultivation for silage: in intercrop with palisadegrass and in intercrop with palisadegrass and pigeon pea cultivar BRS Mandarim, harvested at 0.45 m in relation to soil surface, and grains with 35% moisture. The experimental design of the second experiment will be in a split-plot scheme. The treatments of the first experiment constitute the plots and oversowing black oat cultivar EMBRAPA 29 (Garoa) by broadcasting or in row after harvest for silage constitute the subplots, where will be allocated lambs for grazing in the method of rotational grazing with variable stocking rate and supplementation with ration (concentrate more silage of the same treatment). Will be evaluated the fraction of the corn plants, the forage yield and silage chemical composition; and effect of oversowing black oat on: dry mass yield of the pasture, and performance, carcass characteristics and economic viability of lamb's finishing in semi-feedlot. The results will be submitted to ANAVA by F test and means will be compared by LSD test (pd0.05).
