Effect of varying level of ginger powder in the diet of starter turkeys on performance, haematological and serum biochemical indices

Abstract

Dietary inclusion of various phytogenic additives has been used as alternative growth promoters in poultry. They enhance performance and stabilize health status of farm animals. This study was conducted to investigate the effect of inclusion of ginger powder to the diets of pre starter and starter turkeys at different levels (0g/kg, 2g/kg and 4g/kg) on its performance and some blood parameters. A total of one hundred and twenty day- old British United Turkey (BUT) poults were allotted on weight equalization basis into the 3 dietary treatments in a complete randomised design. Forty poults were assigned to each treatment group replicated four times with 10 poults per replicate. The study lasted for 56 days comprising of the prestarter (0-28 days) and starter (29-56 days) phases. At the pre-starter phase of the experiment, growth performance was not affected (p>0.05) by ginger powder inclusion while the starter phase showed improved (p<0.05) final weight, feed intake and feed conversion ratio. Final weight increased (p<0.05) with ginger inclusion in the diets, while feed intake reduced linearly as ginger inclusion increased. Supplementation with ginger reduced haemoglobin and RBC of the pre starter turkeys. The RBC increases linearly (p<0.05) as ginger supplementation increases with starter turkeys. Serum albumin improved significantly (p<0.05) following dietary inclusion of 2 g/kg ginger powder at the starter (3.37g/dl) phase. In conclusion, starter turkeys fed diet containing ginger at 2 g/kg showed improved growth with improvement in hepatic enzyme activities.
