Effect of herbal extracts on serum minerals,lipid profile and anti-NDV-HI antibody levels of vaccinated broiler chicks

The present study was designed to evaluate the effects of different herbal extracts on the skeletal strength,nervous system,lipid profile and anti-newcastle disease virus-hem-agglutination inhibition (anti-ndv-hi) antibody levels of the newcastle disease virus (ndv) immunized broiler chicks. the study was conducted on seven groups of one day old broiler chicks labeled as a,b,c,d,e,f and g (each containing 15 birds) in three replicates of five birds. each bird of the group a,b,c,d,e and f was fed with 0.2% aqueous extract of aloe vera,zingiber officinale,safi,allium sativum,probiotic (dahi) and curcuma longa in addition to the basal diet,respectively. group g was kept as control,fed on basal diet only. serum levels of cholesterol,triglycerides,sodium,calcium and anti-ndv-hi antibody titer were measured. during this study,it was observed that the garlic extract increased the serum level of calcium while it decreased the cholesterol level in broiler chicks. so these two results with respect to garlic were significantly different from other herbs which show that garlic probably increased the calcium absorption in intestine and resultantly enhanced the skeletal strength. on the other hand garlic also decreased the total cholesterol level in blood making the broiler meat presentable for heart patients. there was no significant effect of any of the herbal extracts on the anti-ndv-hi antibody level of the broiler chicks. copyright 2016 zoological society of pakistan.
