Abstract: 

In a completely randomized design, effect of different levels of sulfur amino acids (SAA) in broiler starter diet on weight gain (WG), feed intake (FI) and feed conversion ratio (FCR) were investigated. Tow hundred and eighty eight Ross 308 day old broiler chicks divided into 16 groups. Dietary treatments were four levels of 0.7, 0.8 (NRC recommendation), 0.9 and 1.0% of sulfur amino acids. FI, WG and FCR were measured weekly. Heamatological indices were measured at 21 day old. In 8 to 14 days, WG of chicks that receiving 0.9 and 1.0% of SAA were significantly (p£0.05) greater than 0.7% SAA fed group. In 15 to 21 days, 0.7% SAA fed group significantly (p£0.05) had lower WG and FI than other groups. In 15 to 21 days, 0.7% SAA fed group significantly (p£0.05) had lower FI than other groups, only. In 15 to 21 days, FCR of chicks receiving 0.9% of SAA were significantly (p£0.05) lower than 0.7% SAA fed group. In day 21, 0.7% SAA fed group significantly (p£0.05) had lower final weight than other groups. Dietary treatments had no effect on heamatlogical Indices. On the basis of this investigation, it seems, the level of SAA in broiler starter diet that recommended by NRC (1994), is sufficient.
