Abstract EN

The present study was designed to investigate the positive effects that may result from the use commercial organic acids mixture X-Mold Cid® and pomegranate peels as nutritional supplements to reduce the severity of infection with Salmonella by reducing the bacterial count and reduce the infection and incidence or shedding rate.

The experiment included the study of efficiency of additions food additives mentioned against the experimental infection of Salmonella enteritidis, 120 chicks aged 5 days divided in to four groups each group contain 30 bird were used, the first group represented the negative control and dealt with the basic diet and the second group represented the positive control has dealt with the basic diet and was given a challenge dose (1 × 108 ml / cfu) of the S.

enteritidis bacteria.

The two other groups were challenged by the same dose, the third group give pomegranate peels with dose of 5 g / kg feed and the fourth group give a mixture of organic acids at a dose of 1 ml / L of water.

The experiment lasted for 40 days for evaluating the efficiency of food additives against Salmonella enteritidis.

The results showed good ability of both additives in reducing the severity of the infection by reducing the shedding rate of the S.

enteritidis and the percentage of infection of cecal contents as well as the total number of bacteria.

Some blood parameters have been studied also which included a number of white blood and the ratio of H / L cells, the study recorded the increase significantly (P <0.05) in white blood cells rate and a significant decrease (P <0.05) in proportion H / L in treated groups.
