THE DIETARY EFFECT GINGER (Zingiber officinale) AND GREEN TEA (Camellia sinensis) POWDER ON THE GROWTH AND MEAT YIELD PERFORMANCE OF BROILER

Abstract

This study was conducted to determine the efficacy of the dietary effect of different levels of Ginger (Zingiber officinale) and green tea (Camellia sinensis) powder on growth performance and carcass traits of commercial broiler. The study was conducted at the Central Poultry farm of Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period from 23 June to 20 July, 2023. A total of 120, day old broiler chicks (Hubbard-EP) were randomly and equally distributed to 4 groups having 3 replicates of 10 birds each. The birds were grouped as T0, T1, T2 and T3 group without Ginger and Green tea powder (control group), Ginger powder 0.5gm/kg feed, Green tea powder 0.5gm/kg feed and (Ginger powder 0.25g and Green tea powder 0.25g)/kg feed respectively. Body weight gains, Feed Conversion Ratio (FCR), mortality (%) and meat yield traits were recorded. The collected data were analyzed by using ANOVA with SPSS version 20. Feed intake (g/bird) was significantly (P<0.05) differed among the dietary treatment groups. The highest feed intake was significantly (P<0.05) higher in T3 (2190.16±33.22), followed by T1 (2176.97±41.4), T0 (2127.96±20.72) and T2 (2070.74±12) respectively. Body weight gain (g) and FCR were significantly (P<0.05) differed among the dietary treatment groups. The highest body weight gain (g) was observed significantly (P<0.05) higher in T2 (1561.63±16.79), followed by T3 (1509.51±6.11), T1 (1496.66±19.88) and T0 (1416.93±8.64), respectively. The highest FCR was found in T0 (1.50±2.40) and the lowest FCR in T2 (1.33±0.66), the intermediate in T1 (1.48±0.06) 1.45±2.08) and T3 (1.45±5.44), respectively. It was found that there was significant (P<0.05) difference among the dietary treatment groups in case of live weight (g), carcass weight (g), breast weight (g), thigh meat weight (g), but there was almost similar (P>0.05) among the dietary treatment groups in case of head weight (g), shank weight (g), liver weight (g), heart weight (g), spleen weight (g), intestine weight (g). Live weight, carcass meat weight, breast weight thigh weight was significantly (P<0.05) higher in treatment T2 group compared to control group T0. Mortality was found in T0 (3.33%) and in T2 (3.33%) dietary treatment groups during experimental period. Based on the result it could be concluded that green tea powder 0.5gm/kg feed may be used in broiler diet as growth promoter and it may also serve as an antioxidant.
