Introduction & Objective

Traumatic bloat (TRP) is a common disease of cattle that is caused by the performance of the digestive, feeding and reproductive systems of ruminants. Rumination of the rumen by sharp external objects in the animal's diet, following the physiological contractions of the rumen and rumen before and after rumination, often leads to peritonitis and can cause involvement of other organs as well. This disease in cattle is of great economic importance due to the decrease in production and high death rate. The purpose of the present study is to investigate the possibility of presence external bodies and their types in seemingly healthy cattle for slaughter in Khorramabad slaughterhouse.

In order to carry out this study from February 2014 to May of 2014, a total of 40 times were made to Golshan Khorramabad industrial slaughterhouse and the study was done on 2400 slaughtered (male and female). In each case, except for registering the sex, the age of the animal was determined from the dental formula and based on this, animals were divided into 4 age groups (under 2 years, 2-4 years, 4-6 years and top of 6 years old).

Adhesion of reticular was observed in 896 under reviewed Cows. Statistical analysis shows differences between two sexes and different age groups of adhesion existence (p<0.01). There were external objects in rumen and reticulum of 1500 cows (%62.5), while 186 pieces metal external objects had perforated wall of reticulum of 165 cows.

Regarding the presence of external objects, A significant statistical difference was observed between the two sexes and different age groups (p<0.01). Also, relationship between adherence and presence of external objects in under reviewed Cows was meaningful (p<0.01).
