Twenty-five gilts, from 30 to 60 kg LW, maintained in cold environment, were used to evaluate the effect of levels of digestible energy (DE) from 3100 to 3700 kcal/kg of diet on the performance, carcass composition and blood serum concentrations of free T3. The daily weight gain was not influenced by the dietary DE level, however, linearly influenced the dietary and protein intakes. The feed:gain ratio linearly improved with the increased of the dietary ED level. The DE intake linearly […]
