Effect of feeding lysine and methionine on some production performance and blood picture parameter of broiler chickens

الملخص EN

The study aims to determine the effect of feeding lysine and methionine on some blood and productivity traits of broiler chickens.

Seventy five (Ross breed) birds one day old were been breeding and grouped randomly into three equal groups as follows: T1 control group, T2 lysine group, T3 methionine group.

Chicks were housing and feeding for 42 days.

Results were show a significant (P <0.05) weekly increase of body weight of lysine and methionine groups (2729.45 g, 2741.25 g) respectively than the control group (2515.20 g), and feed intake (4678.73 g, 4680.03 g) compared with control group (4586.93 g).

Also a significant increase in (PCV) (9.53, 9.65%) and the number of red blood cells (2.98, and 3.15 × 610 / ml3) and the concentration of Hb (9.62, 10.01 g / 100 ml of blood) than the control group and there is significant increase in the number of white blood cells.

So can give lysine and methionine to increase productivity qualities and blood for poultry.
