Effect of spirulina platensis as a dietary supplement on broiler performance in comparison with prebiotics
Hussein A. Kaoud
ABSTACT: A trial was conducted to investigate the effects of dietary supplementations of prebiotic (Lactose and Myco) and Spirulina platensis on broiler performance, carcass yield, and organs weights. Six hundred 1-d-old broiler chicks were randomly assigned to 1 of 4 dietary treatments for 6 wk. The dietary treatments were 1) control, 2) basal diets supplemented with prebiotic (lactose) (1 kg per ton of feed), 3) basal diets supplemented with prebiotic (Myco) (1 kg per ton of feed), 4) basal diets supplemented with dry powder Spirulina platensis (1 kg per ton of feed). The body weights, average daily weight gain, carcass yield percentage, and feed conversion rate were significantly (P < 0.05) increased by the dietary inclusion of the prebiotic and Spirulina platensis as compared the control fed broilers. In conclusion, the prebiotic and Spirulina platensis supplementation significantly increased BW and decreased feed gain ratios and decreased the mortality. The Spirulina platensis offers a good alternative to improve poultry production.
