Abstract

This study was conducted to evaluate the effects of Whey on the performance, biochemical parameters of blood and immune response in broilers. A total 250 day-old Ross 308 male broiler were randomly distributed in 25 experimental units including 5 treatments with 5 replicates. The experimental diets included control, Whey (at 4, 8 and 10% levels) and 0. 1% of commercial probiotic (multifactorial 100). The analysis of data showed that the addition of probiotic and Whey at 4% to broiler diets decreased the feed conversion ratio during the starter and finisher period (P<0. 05). In the grower period, adding 4 and 8% Whey resulted in an increase in body weight compared to diets contained 10% Whey (P<0. 05). The Antibody titer against SRBC were higher at adding 4 Whey in 35 days and were higher at 4 and 8% Whey at 42 days (P <0. 05). The Immunoglobulin M and G titer were not affected by experimental treatments at 35 and 42 days of age. The probiotic and Whey at the level of 8% decreased serum Cholesterol and also probiotic and Whey at the levels of 4 and 8 levels decreased the concentration of LDL as compared to control (P≤ 0. 05). The level of 8% Whey increased the depth of the crypt and the Height of villi to the crypt depth ratio compared to the control (P<0. 05). Whey and probiotics increased the relative weight of bursa of fabricus and decreased abdominal fat percentage compared to the control group (P <0. 05). Therefore, the findings showed that supplementation of Whey up to 10% does not have undesirable effects on performance, it suggested that addition of Whey up to 4% to broiler diets may reduced Cholesterol, and FCR and improve the immune response of broiler chickens.
