This experiment was conducted to determine the effect of methionine to lysine ratio on growth performance of 10 kg kilogram pigs. The experiment treatment diets containing four different methionine to lysine ratios (27:100, 33:100 and 45:100). Average daily weight gain was highest in pigs fed 39:100 showed significant (P<0.01) were 265 g/h/d greater than 33:100, 27:100 and 45:100 were 248, 233 and 212 g/h/d respectively. Similarly, feed conversion ratio were 1.70, 1.82, 1.93 and 2.13 respectively. Furthermore, pigs fed 39:100 showed higher protein efficiency ratio than pigs fed 33:100, 27:100 and 45:100 (P<0.01) were 2.95, 2.76, 2.59 and 2.35 respectively. Body weight loss of pigs fed protein free diet were 129 g/h/d. Net protein ratio showed highly significant (P<0.01) were 4.38, 4.19, 4.02 and 3.79 respectively. In conclusion, methionine to lysine ratio as 39:100 was best recommended for requirement of 10 kilogram pigs.
