| Abstract | ||||
| This study was carried out at the poultry farm of Animal Resources Dep./ college of Agriculture / University of Baghdad during the period from 1-5-2011 to 31-8-2011, to study the effect of a new local oily injectable cadmium complex (CAC) [Di nitrate- bis {p-methyl anilino phenyl aceto nitrite} cadmium (II)]-2H2O with molecular formula [Cd (HL) 2(NO3)2] - 2H2O in layer hens to control ovaritis and salpingitis and its effect on egg quality traits. 60 healthy Lohmann Brown laying hens 49 weeks age were used in this study. The hens were randomly distributed into five treatments،each treatment included three replicates (4 hens / replicate). The CAC was injected subcutaneously in layer hens neck at different levels where T1: 0.0% (uninjected, uninfected as normal control), T2: 0.25% ، T3: 0.50% and T4: 1.00%. After five days T2 , T3 ,T4 and T5 were orally administrated with E.coli by drinking water at concentration of 8500×106cells/ ml (highly pathogenic) as causative agent of Salpengitis and Ovaritis,while T5 assumed as uninjected treatment but treated with E.coli. The results revealed that the treated birds (T2, T3, and T4) showed a resistance against E.coli infection. However, birds injected with 0.50%CAC(T3) showed superiority in egg weight as compared to control group T1,T2 and T4, respectively, during the production weeks 57-60 and 61-64 as well as at the total mean of the experiment 49-64 wks.T3 also showed superiority in albumen weight during these two production periods as compared to T4, while the mentioned treatment (T3) showed superiority over all other experiment groups in weight and height yolk at the total mean of the experiment ,and in yolk index during the two production periods 49-52 and 53-56 wks. However, no significant differences among different treatments in shell weight, shell thickness, albumin height and Haugh unit. The results also showed that the liver and egg samples of treated birds were free from cd (11) ion residuals. The obtained results refered to the safety use of CAC as a synthetic chemical prophylactic agent against E.coli during the production period of layer hens. | ||||
