AMELIORATIVE EFFECTS OF Withania somnifera ROOT POWDER ON GROWTH PERFORMANCE OF CADMIUM TREATED CHICKENS1
99 / 24
Abstract
ABSTRACT
A total of 90 chicks of one day age were divided randomly into five groups of 18
birds each viz. Group I (control), group II (100 ppm cadmium), group III (200 ppm
cadmium), group IV (100 ppm cadmium + Withania somnifera root powder, WSRP) and
group V (200 ppm cadmium + WSRP). Groups IV and V were administered WSRP
orally in standard recommended feed at the rate of 1% concentration from 2 weeks of
age till 60 days post treatment (DPT). Clinical signs, Body weight, feed consumption,
body weight gain and feed conversion ratio were studied at 0, 15, 30, 45, 60 DPT. Birds
in all the experimental groups were examined twice daily in morning and evening for
recording of clinical manifestations, if any. Birds in groups I and IV were active, healthy
and bright in appearance. In groups II and III, the birds showed decreased feed intake,
weakness, lethargy, dullness and depression from 10th DPT upto 60th DPT. However,
incoordination of movement was also observed in groups II and III from 30th DPT to 60th
DPT. In group V, no other clinical signs were observed except dullness. There was dose
and time dependent significant decrease in body weight, feed consumption, body weight
gain but significant increase in feed conversion ratio. Withania somnifera, administered
@ 1% in feed, in cadmium intoxicated birds @ 100 ppm and 200 ppm, minimized the
adverse effects of cadmium.
Key words: Withania somnifera, growth, performance, cadmium, chickens.
