Abstract: The aim of this experiment was to study the effect of different primrose seeds level on growth in young quails. 150 quails of 1 day age were divided into 5 groups randomly,each group of 3 repetitions,and each repetition of 10 quails. The first group was the control group of feeding basal ration,and the others was treatment groups of feeding evening primrose seeds (triturated) of 8%,10%,12%,15% on the basal ration. All of the quails were raised for 35 days. The results indicated that slaughter traits were not significantly affected in young quails fed primrose seeds (P＞0.05), and slaughter weight, eviscerated weight and breast muscle rate in young quails fed primrose seeds were numerically higher than the control group. There were no significant difference for the heart,liver, spleen and bursa of fabricius index in young quails fed different diets (P＞0.05). Therefore, it could be concluded that primrose seeds could be used in young quails’diet safely.

Key words: primrose seeds; young quail; slaughter trait; internal organ index
