Effect of supplementation Artemisia herba, Curcuma longa, Thymus vulgaris and Nigella sativa in diet on some microbial character of broiler chicken

Abstract

This study was aimed to investigate the effect of supplementing different concentration of Artemisia herba, Curcuma longa, Thymus vulgaris and Nigella sativa and the mixture of Thymus vulgaris and Nigella sativa in diet of broiler chicken (starter diet contain 21.96% crude protein, 2966.7 Kcal/ Me and grower diet contain 19.93% crude protein, 3084.9 Kcal\ ME) on some microbial character of broiler chicken. In the first experiment 225 chicks as Ross strain unsexed were used one day old to 42 days the chicks distributed randomly on five treatment each one have 15 chicks replicate (45 chicks\ treatment) the supplementing of Curcuma longa, Thymus vulgaris to diet as follow T1 contain standard diet without any supplement T2, T3 contain 5,10 kg/ ton Thymus vulgaris, T5, T6 contain 5,10 kg\ ton Curcuma longa. The second experimental, 315 chicks unsexed Ross strain one old were distributed randomly on 7 treatment, 15 chicks for each replicate (45 chicks\ treatment) as follow: T1 contain standard diet without supplement, T2, T3 2.5 and 5 kg\ ton Artemisia herba, T4, T5 2.5 and 5 kg\ ton Nigella sativa, T6, T7 2.5 and 5 kg\ ton mixture of Artemisia herba and Nigella sativa. The results were reveals a significant decrease (P<0.05) in total aerobic bacteria count and coliform count in intestine content of broiler chicken in contrast with control treatment the result of experimental showed the Thymus vulgaris and Nigella sativa supplement have high effect on decrease the total and coliform when compare with Curcuma longa, Nigella sativa. The result of study confirmed that the mixture supplementing Artemisia herba, Nigella sativa have position effect to decrease the number of total and coliform when contrast where other treatment.
