Abstract EN

This study was carried out at the Poultry farm of Animal Resource, College of Agriculture, Tikrit University from 28/3/2013 to 2/6/2013 The present study was conducted to explore the usage of different levels of Neem (Azadirachta indica) Seeds powder and aqueous extract to Performance, Physiological and producing of the Broiler Chickens, used in the experiment 525 chicks of broiler non-naturalized hybrids (Hubbard), day-old.

The chicks were distributed randomly to seven treat- ments each treatment has three replicate and each replicate has 25 chicks were as follows: T1.

Control without any addition, T2.T3.T4.

Add Neem seeds powdered to feed ratios of 1.5, 2 and 2.5 g / kg feed respectively, T5.T6.T7.

Add extract Neem seeds to drinking water rates 20.30 and 40 ml / liter of water respectively, The results of the study showed that: No significant differences (P <0.05) forred and white blood cells, PCV (%) andhemoglobin concentration of among all experimental treatments, the results showed a significant decrease (p <0.05) inserumglucoseconcentration level with no significant difference to the level of uric acid, the concentration of total protein, albumin and total globulin among all treatments.

The results showed significant reducing (p <0.05) in cholesterol and enzymes (GOT and GPT) concentrationof the treatments add the Neem seeds to the feed or drinking water, compared to the control group, the absence of significant differences (p <0.05) in each of the villus length and depth of the crypts and the relationship between them for the ileum of broiler chickens between different groups.

We conclude from this study use of Neem seed powder or aqueous extracts did not have a negative impact on traits of blood and has had a positive impact on the functions of the liver and the concentration of cholesterol.
