Abstract

The present work evaluated the effects of the ap-plication of different amounts of liquid pig waste (LPw) in the manuring of Brachiaria brizantha cv. Marandu in relation to the chemical manuring usually recommended, as the production and composition chemist - bromatológica during the period from January at April/00. The treatments consisted of T1 = it controls, T2 = chemical manuring (60 kg/ha of N in form of sulfate of ammonium, 30 kg/ha of P in form of simple superfosfato and 37,5 kg/ha of K in form of potassium chloride), T3 = 50 m³/ha, T4 = 100 m³/ha and T5 = 150 m³/ha, being the  LPw,manurings divided in three applications. The used experimental deli-neament was it of blocks complete casualizados, with four repetitions. They were appraised: production of dry matter (PMS) (kg/ha), medium tenors of rude protein (PB), fiber in neutral detergent (NDF), fiber in acid detergent (ADF) and hemicelulose (HC), besides the medium tenors of the macrominerals: match (P), potassium (K), calcium (Ca) and magnesium (Mg). The manuring with dejections and the chemical manuring provided significant increments in PMS of the grass Marandu. The application of LPW influenced the composition bromatologyc of the forage, as well as the chemical composition. For the found results the application of 150 m3 of DLS can be recommended to substitute the recommended chemical manuring. 

KEY-WORDS: ADF, cruden protein, mineral macroelements, NDF, production of dry mater.
