Treatment diets consisted of three levels of supplemental lysine in starter and grower period (0, 0.15, and 0.30 %) and the two levels of protein (20.84, 17.84 in starter, and 18.12, 16.12% in grower period) with 2900 Kcal ME/kg diet. The results indicated that the Reducing dietary protein decreased significantly the weight gain in starter, grower, and total period up to 6, 4.6, and 5.6%respectively (P }, URL = {http://jstnar.iut.ac.ir/article-1-510-en.html}, eprint = {http://jstnar.iut.ac.ir/article-1-510-en.pdf}, journal = {Journal of Water and Soil Science}, doi = {}, year = {2006} }
