|
To determine the effect of dietary potassium and lysine levels on blood parameters, serum and bone composition, 360 male broiler chicks of 3 days of age were used in a completely randomized 3 횞 3 factorial experiment for 6 weeks. Experimental diets contained three supplemented levels of dietary potassium (0.3, 0.6 and 1.2%) and three supplemented levels of dietary lysine (0.6, 1.2 and 2.4%). Dietary levels of potassium and lysine did not influence blood pH, pCO2, pO2, HCO3 and total CO2 and interaction between potassium and lysine was not shown (p>0.05). Serum lysine and arginine contents were significantly different by the levels of dietary lysine (p<0.05). Lysine-arginine antagonism was observed in high lysine diet. But increasing dietary potassium did not alleviated the alleviated the lysine-arginine antagonism. Serum sodium, potassium and chloride were not affected by the levels of dietary lysine (p<0.01). But no difference was observed in femur ash and Ca contents (p>0.05). Interaction between potassium and lysine was shown in ash and P contents (p<0.01). |
