    SUPPLEMENTATION OF Asparagus racemosus (SHATAVARI) ON THE GROWTH PERFORMANCE, IMMUNE STATUS, GUT HEALTH AND CARCASS CHARACTERISTICS IN GIRIRAJA BIRDS

    An experiment was conducted to study the supplementation of Asparagus racemosus on growth performance, immune status, gut health and carcass characteristics in Giriraja birds. A total of 150 day old Giriraja chicks were distributed into five treatment groups with three replicates in each group and ten chicks in each replicate. Basal diet (T1) and the experimental diets were prepared by incorporating Shatavari at 0.25 per cent (T2), Shatavari at 0.50 per cent (T3), Shatavari at 1.0 per cent (T4) and Shatavari at 1.50 per cent (T5). The results revealed significantly (P ≤ 0.05) higher body weight, lower feed intake and better feed efficiency compared to control and no significant (P > 0.05) difference in survivability among treatment groups compared to control. Significant (P ≤ 0.05) improvement on immune response against Infectious bursal disease and no significant (P > 0.05) difference on immune response against Newcastle disease was observed. Significant (P ≤ 0.05) increased in weight of bursa of fabricius and non-significant (P > 0.05) difference observed in weight of spleen and thymus. Significantly (P ≤ 0.05) lower serum cholesterol levels and LDL values observed in test diet compared to control group and no significant (P ≤ 0.05) difference observed in HDL. Supplementation of Asparagus racemosus at 1.0 per cent revealed low E. Coli counts and high Lactobacillus spp. counts. Significantly (P ≤ 0.05) higher in dressing percentage, breast yield, thigh yield and weight of gizzard, respectively in test diet and non-significant (P > 0.05) difference in abdominal fat percent, drumstick yield and weight of heart, liver, kidney and proventriculus. Based on the above result it was concluded that supplementation of Asparagus racemosus at 1.0 or 1.50 per cent was beneficial in improving body weight, feed intake, feed efficiency, immune response, gut health, carcass characteristics and lowering the serum cholesterol content in Giriraja birds.
