Study the effect of adding aqueous extract of clove (eugenia caryophyllus)‎ to drinking water in productivity and physiological efficiency of broiler chicken

الملخص EN

This study was to investigate study the effect of adding the aqueous extract of clove (Eugenia caryophyllus) by two different levels to drink water to improve the productive efficiency and some physiological characteristics of the broiler.

The study was carried out on 180 chicks of Hubbard at one day old.

They were divided randomly into three groups (60 bird in each group) with three replicates for each group (20 bird for each replicate.

In this experment, the bird was given two types of diets, the first diet was a starter that has been feeding on the 1-2٢ day age-old , whereas the second diet was finisher that has been feeding on 2٣-4٨ day age-old.

The experimental treatments divided into three groups.

In control group, birds drink free water without any addition.

In group T1, birds received 1% of aqueous extract of clove flower in drinking water, whereas group T2 received 5% of aqueous extract of clove flower in drinking water.

The current study showed a significant improvement (p <0.05) in the production efficiency of birds.

Its included weight of the body, weight gain, feed conversion ratio, feed and water consumption rate, decrease in mortality rate and improvement in some blood traits including haemoglobin, white blood cell WBC, packed cell volume PCVin treatment groups(T1, T2) compared with control group.

As well as the results showed a significant decrease (P <0.05) in the glucose level, cholesterol, urea and creatinine in both of treatment groups compared with the control group that intake water free from an aqueous extract of clove.

From this study, we concluded that adding of aqueous extract of clove flower at different concentrations led to improved productive and physiological effects of broiler chicken.
