Resumo


Evaluated partial substitution of commonly used concentrate mixture by jurema preta (Mimosa tenuiflora) pods (JPP) in the diet of Santa Inês lambs of according to a randomized complete block design with three treatments (0, 10 and 20% concentrate substitution, in a 40:60 concentrate: roughage fodder diet) and six replications, using 18 non-castrated Santa Inês male lambs with initial body weight of 20.28±1.18 kg. Analyzed variables were apparent coefficients of digestibility and/or daily donsumption of dry matter (CDDM and CDM), organic matter (CDOM and COM), neutral detergent fiber (CDNDF and CNDF), acid detergent fiber (CDADF and CADF), crude protein (CDCP and CCP), crude energy (CDCE only), ether extract (CDEE and CEE), total carbohydrates (CDTCH and CTCH), non fibrous carbohydrates (CDNFC and CNFC), metabolizable energy (CME) and water (IH2O), mean daily body weight gain (MDBWG) and food conversion (FC). There were no effects (P>0.05) of JPP on digestibility, except for the quadratic effect (P<0.05). Mean daily body weight gain, consumption and food conversion were not affected (P>0.05), consumption of CP, NDF, ADF and EE increased linearly, while CNFC decreased linearly. Jurema preta pods can be included in the diet of lambs and may contribute to the sustainability of the sheep activity in the semiarid region of northeast Brazil.
