Abstract EN

This Study was conducted in the hatchery of AL-Anwar Poultry Company-Babylon province.

The aim of this study was to find out the effect of early feeding injeuction (IOF) with different levels of AL-Carnitine Solution on villi length , villi width and crypt depth character.Egg used were from laying hens flocss (Ross 308) in the age of 33weeks.Eggs divided into five groups (Treatments) with 60 eggs per treatment (group) as follows : T1 negative control treatment( without egg injection),T2 positive control treatment (eggs injected by distilled water only) ,T3,T4,T5 treatments (the eggs injected by carnitine solution with concentration of 5%,7%,9%) respectively.

The hached chicks were reared from the period (29/9/2015 until 2/11/2015) the results obtained from this study were as follow: 1) Highly significant superiority (p<0.01) in T4 and T5, in villi length for the duodenum andjejunum of the small intestine compared to control treatments (T1 and T2).

Also, significant superiority in the villi length in the Ileum in the small intestine for T3 compared to T1.

2) Highly significant superiority (p<0.01) in villi width for the duodenum of the small intestine for T4 and T5 compared to control treatments T1 and T2 where T5 was the best in thischaracter.

3) Significant superiority (p<0.05) in villi width for jejenum in the small intestine for injected treatments compared to the control .

4) Highly significant superiority (p<0.01) in crypt depth character for the duodenum in the small intestine for T4 and T5, compared to other treatments.

5) Significant superiority (p<0.05) in crypt depth for the jejenum in the small intestine for T4 compared to T2.
