Clinical study of an outbreak in feedlot cattle by poultry litter consumption

Laboratorio de toxicología, Mexico
A
clinical study in a feedlot cattle in Michoacan is described.
The disease occurred in November 2017, in a feedlot beef
cattle herd, 35 out 130 were affected. Clinical signs included
anorexia, diarrhea, tachycardia, dyspnea, low weight gain and
four animals, corneal opacity. The animals were fed with rations
of grains (50%), poultry litter (35%), soybean paste (10%)
vitamins, mineral salts (5%) and roughage. Daily water intake
was low since there were no drinking sources. The treatment
consistedinantibiotics,vitamins,antihistaminesandhepatonics.
Three months later, 64% of the animals were blind. The clinical
diagnosiswas poultry litter intoxication. Samples of poultry litter
and water were collected from the production unit to confirm
the diagnosis. Lead (Pb), mercury (Hg), chromium (Cr), copper
(Cu), arsenic (As) andcadmium(Cd)wereanalyzedby theatomic
absorption spectrophotometry technique coupled to a flame
detector; phosphorus and sulfates by UV light spectrometry.
Mercury and copper in the poultry litter were found out of the
recommendations. In the water, arsenic, mercury and sulfates
were found outside too. It is concluded an acute poisoning by
Cu associated with Hg by exposure of bovines to contaminated
water and poultry litter. Thewater contaminated caused a lower
consumption due to taste, and a low nutritional performance
reflected in the clinical picture of the intoxicated animals.
