Newly weaned rabbits are more susceptible for colonization of various microbes in gastrointestinal track. The study was taken up in the Central Sheep and Wool Research Institute, Avikanagar (Rajasthan, India). Sixty weaned rabbits of almost same age (28 days old) and similar initial live body weight were selected and distributed into four groups (T₁, T₂, T₃ and T₄ groups) of fifteen each. The diets were given in pelleted form and ad libitum throughout the trials. The pellet feed for the T₁ group was not supplemented with probiotics while the pellet feed for groups T₂, T₃, and T₄ was supplemented with Lactobacillus plantarum (Lp), Saccharomyces cerevisiae (Sc), and a combination of Lactobacillus plantarum and Saccharomyces cerevisiae (Lp + Sc), respectively. The microbial population was 10⁶ CFU/g pellet feed. The result indicates significantly ((p<0.05) decreased serum cholesterol level and non-significantly increased serum total immunoglobulin level were found in probiotics supplemented groups. Improved blood antioxidant property found in probiotics supplemented groups.
