Effect of added levels of Clove (Eugenia aromaticum) extract on the performance, some immune response, Blood Constituents and some Carcass characteristic of broiler chicks

Abstract

This study was conducted to evaluate the response of broiler chickens to adding graded levels (0g/l -250g/l -500g/l -750g/l) of clove extract in drinking water. The study measured included production performance, immune response, some carcass characteristics, attributes and economic evaluation impact. The experiment birds were randomly distributed into four treatments using a completely randomized design. 200 one day old chicks (Cobb500) were used. They were divided into four treatments, each containing 50 chicks, and each treatment consists of five replicate 10birds each. The experimental feed was formulated to be isocaloric and isonitrogenous to meet the nutritional requirements of broiler chickens issued from NRC (1994), the experimental chicks were fed for 5 weeks as experimental period and at the end two birds for each replicate were taken for slaughtered measurements. Results of this study showed that added clove to drinking water chicks was revealed a significant improvement in the percentage of feed consumed, total weight gain and carcass weight. The results showed that a highly significant differences (P<0.01) among experimental groups in feed intake, weight gain and final body weight gain. Group B of 250g/l clove level concentration was superior values for above parameters while significant improvement of (P<0.05) were recorded by group drinking clove extraction. Also addition of clove extraction appeared a significant improvement of economical impact. Percentage of concentration of 250g/l was given a highest values among the experimental groups while 750g/l is most profitable. Therefore, cloves can be introduced as a natural feed additive in the drink water of broiler chickens.
