In a dairy farm located at Hilat Kuku, Khartoum North, Sudan, a crossed breed dairy cow was observed displaying an abnormal clinical sign in the molasses preparation hole for five days. This sign puzzled most of the clinician who were called to attend to the case. The mean frequency of display was 3.6±0.5 times/day and the mean time spent in the molasses preparation hole displaying the unusual posture was 31.56±16.64 minutes. Means of vital clinical parameters in five days were 39.6±0.7 C°, 45.2±2.4/ minute, 86.0±4.2,1 / minute, 1. 2±0.5 / 2 minutes for temperature, respiratory rates, pulse rates and rumen contraction rates respectively. Exploratory rumenotomy revealed presence of a 32 inches long wire entangled in reticular content and perforated reticular wall to became lodged into diaphragm. Mild localized signs of peritonitis were observed. The study concluded that, this unusual sign can be considered among the clinical signs for diagnosis of cases of traumatic reticulo-peritonitis.
