| Summary: | This study aimed to quantify the occurrence of gallstones in cattle slaughtered in the microregion of
Campos da Mantiqueira, and draw a profile of the animals affected by cholelithiasis. The present study was
conducted in slaughterhouse of São João Del Rei, MG, that receive animals from the various region cities
for slaughter. ID's registration number, breed, sex, body condition score (scale 1-5) and age of these
animals were estimated. A check for pregnancy in females was performed. The gallbladder was removed
intact, for analysis of the presence of gallstones. The liver was examined and data relating to liver problems
were reported. The recovered gallstones were weighed. For data analysis, we proceeded to calculate the
frequency of cases of gallstones in cattle studied. Among the cases of cholelithiasis observed, we calculated
the percentages of animal origin, race, sex, pregnancy, age and ECC in order to draw a profile of affected
animals. Moreover we studied the correlation between gallstones and liver problems. 91 cases of gallstone
(9.79%) among the 929 cattle studied were observed. Crossbred animals were the most affected (59/91),
followed by the Netherlands (30/ 91) race. Regarding sex, females were most affected by cholelithiasis,
totaling 83 cases. And animals with greater than 120 months old comprised 57.1 % of cases. Most gallstone
animals showed ECC 2 (53/91). Most bovine presented only cholelithiasis, without hepatic disorder (72/91).
The average weight of 2.98 grams was recovered calculations, ranging from 0.4 to 23.3 grams. Fasciolosis
(13/91), hemorrhage (3/91), neoplasm (2/91) and Hepatic Congestion (1/91) were observed in association
with gallstones.
