摘要: The use of by-products such as swine manure (SM), poultry waste (PW), urea (U), molasses (M) and bakery by-product (BB) is an alternative method for lamb feeding. objective the present study was to determine chemical composition, dry matter intake digestibility in growing lambs using ensiled PW combined with BB (PWBB), SM (SMBB), M (SMM) U (UM) their diets. Four silages—PWBB, SMBB, SMM UM—were prepared, composition silages determined (n = 3), concentrate ratio (60:40) fresh were given over 21 days total period, collection samples carried out last 7 days, a 4 × 4 Latin square design, significance level P < 0.05. organic (OM) lower (P < 0.05) silage (886 g/kg), crude protein increased UM (206 g/kg) followed by PWBB (170 g/kg). DM, OM, NDF ADF higher diets compared rest treatments; (389 g/kg) than (417 g/kg) N (51.3 g N/day) treatments (39.9 ± 1.3 g N/day). PWBB, or feeding, provided that proper formulation supplies nutrient requirements diminish excretion diet.
