abstract
The present research investigation was carried out to study effect of 50% ethanolic rhizome extract of Zingiber officinale on physical parameters on Lead induced toxicity in broiler birds. 140 broiler chicks were divided into 7 groups each comprising of 20 birds. The toxicity was induced by administration of lead acetate @200mg/kg feed from T₂ to T₇ and T₁ as normal control. T₃ & T₄ was given Ascorbic acid @200mg/kg feed & extract @200mg/kg BW, respectively. T₅ was given Ascorbic acid @200mg/kg feed & extract @200mg/kg BW. T₆ was given extract @300mg/kg BW. Group T₇ received Ascorbic acid @200mg/kg feed and etract @300mg/kg BW. The results showed that, lead treated group with Zingiber officinale extract i.e. T₄ and T₆ and with L-Ascorbic Acid i.e. T₅ and T₇ has suppressed the negative impact of lead on body weight and body weight gain, also by ascorbic Acid alone (T₃). However, all the treatment of Zingiber officinale extract alone and with ascorbic acid does not produced significant positive effect on feed consumption. The feed conversion ratio (FCR) was significantly improved by Zingiber officinale all treatments. Finally, it has concluded that extract of Zingiber officinale alone and with L-ascorbic acid has protective effect against the lead induced toxicity in broiler birds.
