A 16 week feeding trial was carried out to study the influence of dietary inclusion of probiotics and prebiotics on livability, egg shape index and egg shell quality parameters. A total of 140 White Leghorn layers in the age group of 22 to 38 weeks were divided randomly into seven experimental groups containing 4 replications of 5 birds each. In (T1) control group layers were fed a basal diet formulated as per BIS (2007) standards. In treatment groups T2, T3 and T4 hens were fed control diet supplemented with probiotics (containing 5×108 cfu/g of Lactobacillus fermentum, 1×109 cfu/g of Bacillus spp. and 1×109 cfu/g of Saccharomyces cerevisiae) @ 0.5g, 1.0g and 2.0g Kg-1 feed, respectively, and layers in experimental groups T5, T6 and T7 were fed basal diet added with prebiotics (mannan oligosaccharide of Saccharomyces cell wall-47gm, formic acid-32gm, HSCAS-upto 1Kg) @ 0.5g, 1.0 g and 2.0 g Kg-1 feed, respectively. Study results revealed that there was (P<0.05) increase in egg shell thickness, egg shell weight and egg shell percent under different levels of probiotic and prebiotic regimes (T3, T4, T5, T6 and T7) as compared to the control (T1) group. Shell thickness increased from 0.348 to 0.374 mm indicating an advantage of 0.026mm in favour of probiotics and prebiotics. Egg shape index was not affected, however, egg width and egg length were (P<0.05) increased under various levels of probiotics and prebiotics supplementation in comparison to control. The mean body weight gain in hens were not affected significantly and no mortality was observed under different dietary regimes. Thus, result findings clearly indicate that supplementation of probiotics and prebiotics has beneficial effects by significantly improving the egg shell thickness, shell weight, shell weight percentage and egg shape parameters, without affecting health and livability of the layers.
