Effect of different concentrations of aqueous extract of ginger (Zingiber officinale) on performance and carcass characteristics of male broiler chickens in wheat-soybean meal based diets

Abstract
This study was conducted to investigate the effects of using different concentrations of ginger extract (Zingiber officinale) on performance and carcass characteristics of male broiler chickens. Three hundred one-day-old commercial male broilers (Cobb-500) were randomly allocated in 20 floor pens (15 chicks each). Animals of each pen were supplemented with five different concentrations of ginger and the experiment was performed in quadruplicate. The broilers were fed a wheat-soybean meal based diet containing different concentrations of ginger extract (0, 0.25, 0.5, 0.75 and 1%) supplemented to drinking water. Feed intake, body weight gain and feed conversion ratio were measured during 1 to 10, 11 to 21, 22 to 42 and 1 to 42 days of age. At 42 days of age, two birds from each pen were selected and after weighing and slaughtered were dissected manually. Carcass yield, liver, abdominal fat and gut weight is expressed as percentage of live body weight. The results showed that there is no significant difference in the feed intake, body weight gain and feed conversion ratio between the different treatments except the feed conversion ratio of the period 1 to 10 days of age (p<0.05). Also, different supplemented concentrations of ginger extract to drinking water of broilers influenced the carcass yield (p<0.05).
