Abstract

The current study was conducted to assess the consequences of Spirulina platensis extract based on growth performance and immunological response of broiler chicks. There was a total of a hundred and Eighty-one-day-old chicks were assigned at random into three dietary groups undergoing treatment with three replicates of 20 each bird. Control group was given ration without additives. The second and third groups were supplemented with Spirulina platensis extract at doses of 30 and 50 gm./kg. of ration, respectively. Supplementation of broiler chicks with Spirulina platensis extract enhanced their growth performance represented by increasing final body weight, body weight gain, phagocytic activity, and phagocytic index while significantly decreased feed intake and food conversion ratio. Moreover, it increased serum levels of Ig-M, and Ig-G and obviously change in serum level of Insulin like growth factor-1 (IGF-1) but not lead to a significant change as compared to control.
This study indicated that Spirulina platensis extract in ration enhanced the growth performance and immunological response of broiler chicks through increasing serum levels of immunoglobulins.
