Serological positive reaction to enzootic bovine leukosis (EBL) were established by means of agar- gel- imunodiffusion tests applied to 25 beef cattle. The pepsinogen activity in the serologically-positive sera was determined by using Paynters method. The results were compared with those from a group of 30 clinically healthy EBL negative young cattle and those from a group of 10 animals with pathoanatomical abomasal ulcers. Although not statistically significant, the mean pepsinogen activity in the sera of the EBL-positive beef cattle was higher (3.35 ± 2.31 U/L) than in the control group of EBL-negative animals (2.45 ± 1.00 U/L). The sera of the group of animals with abomasal ulcers had statistically significant higher mean value of pepsinogen (6.48 ± 1.80 U/L) than both the control and EBL-positive groups. A comparison of the established mean pepsinogen values confirmed that EBL-associated lymphosarcoma-related alternations on the abomasal mucosa were not manifested in the majority of the younger animals.
