Abstract
An experiment was conducted to study the effect of feeding neem, ginger and
garlic powder on growth performance, lipid profile and immune response in Giriraja
birds. A total of 150 day old Giriraja birds were procured and allocated to five
experimental groups each consisting of three replicates with ten chicks each.
Experimental diets for broiler starter and finisher rations were formulated as per the
ICAR (2013) standards.The basal diet (control) T1 was prepared using corn and soyabean
meal (as per requirement) without supplementation of garlic, neem and ginger for
day 1 to 56 days of experimental period. The experimental diets T2, T3, T4 and T5 were
prepared by incorporating basal diet+ 0.5 % garlic powder, basal diet + 0.5 % neem
powder, basal diet + 1 % ginger and basal diet + 0.5 % garlic powder + 0.5 % neem
powder + 1 % ginger powder, respectively. The results revealed that feeding neem,
ginger and garlic powder individually and also in combination resulted in significant
improvement in body weight, feed intake and feed efficiency whereas survivability
showed no significant difference among different treatment groups. No significant
improvement on immune response against Newcastle disease. But significant difference was
observed in Infectious bursal disease on the 56th day of the experiment and also showed
non-significant (P > 0.05) difference on immune organs weight of birds fed with different
treatment groups except Bursa of fabricius which was significant in group fed with 1 %
ginger and combination. Significant (P ≤ 0.05) reduction in serum cholesterol,
triglycerides, low density lipoprotein and meat cholesterol was observed. Significant (P ≤
0.05) reduction in E. Coli count compared to control group was observed whereas
Lactobacillus count was significantly increased in the groups fed with garlic, neem,
ginger and in combination. Significant difference (P ≤ 0.05) in carcass characteristics like
dressing percentage, breast yield, thigh yield and abdominal fat per cent was observed
and no significant difference (P > 0.05) in gizzard, drumstick yield, heart, liver and
proventriculus of birds. Based on the above result it was concluded that inclusion of
garlic, neem and ginger powder and combination was beneficial in improving growth
performance, gut health, carcass characteristics and lowering serum cholesterol in
Giriraja birds. However feeding of 1 % ginger and combination of 0.5 % garlic powder,
0.5 % neem powder, 1 % ginger powder have more beneficial effects in Giriraja birds.
