“…Furthermore, cow transportation or milking routine changes can cause milk accumulation. Mammary gland engorgement may allow absorption of milk proteins, especially casein, as this is mediated by histamines that increase vascular permeability (3,4), generating type I hypersensitivity (anaphylaxis), as in the present report.…”

Allergy to milk is the only auto-allergic disease in cattle. It is characterized by the retention and absorption of milk itself, making milk proteins, especially alpha casein, have access to the bloodstream, resulting in a type I hypersensitivity. The purpose of this report is to describe a case of auto-allergic disease in cattle. Here we report the case of a four-year-old Jersey female bovine, which was pregnant and weighing 400Kg. The animal was being treated at (hidden for revision) and had a history of an acute allergic reaction. Its owner reported sudden onset of skin lesions, salivation, and difficulty breathing. As the animal was participating in an agricultural exhibition, it was not being milked to generate mammary gland engorgement (milk retention). In physical examination findings wherein there is presence of multifocal urticarial papules and plaques, mainly on the sides and right and left flanks, besides the absence of pruritus, edema in mucocutaneous regions of the upper and lower eyelids of the right and left eyes, submandibular edema, excessive salivation, inspiratory dyspnea with half-open mouth breathing, respiratory distress, apathy, cough, tachycardia tachypnea, ruminal hypomotility and increased volume of the mammary gland, characterizing milk retention. Clinical suspicion was milk allergy with anaphylactic reaction (type I hypersensitivity). Treatment was based on promethazine administration (1mg/kg; IV) and immediate full milking of the mammary gland. After 12 h of treatment, clinical respiratory signs resolved, and after 24 h, skin changes resolved completely. Based on clinical signs and treatment success, the clinical suspicion of milk allergy causing anaphylactic reaction (type I hypersensitivity) was confirmed.

“…An edema originates from exudation from blood vessel walls and lead to development of papules (9). Pulmonary edema is permeable, which occurs due to excessive opening of the interendothelial spaces or damage to the blood-air barrier after release of inflammatory mediators (2,4,11). Abortions have been reported in female bovines affected by milk allergy (1).…”

BackgroundThe prevalence, anatomical distribution, or nature of cutaneous, hair and oral mucosal abnormalities (CHMAs) in cattle is uncertain.ObjectivesTo determine how often dairy cattle admitted to a veterinary teaching hospital (VTH) had CHMAs (except for foot and ear canal) on physical examination and if there was an age‐related difference.AnimalsFour hundred and thirty‐three cattle: cattle <3 months (n = 85), cattle 3 to 24 months (n = 73), and cattle >24 months (n = 275).MethodsIn this descriptive, observational, prospective study, CHMAs of dairy cattle admitted to the VTH of the Université de Montréal were recorded over 1 year. Prevalences were calculated. Dermatological examinations were performed within 48 hours of admission, according to a glossary. Chi‐square tests were used to compare prevalence between age groups.ResultsThe 433 cattle were mostly females (97.5%) and of the Holstein breed (89.8%). The prevalence of cattle <3 months presenting with at least 1 identifiable CHMA was 65% (55/85). In cattle 3 to 24 months old, it was 90% (66/73), and in cattle >24 months, it was 99.3% (273/275). There were significant differences (P < .001) between the prevalence of CHMAs localized on the ischia, ilia, stifles, hocks, carpi, flank, lateral neck, dorsal cervical, and cornual regions in cattle >24 months vs <3 months.Conclusions and Clinical Importance.CHMAs were highly prevalent and age‐specific. Calluses on the carpi and hocks of cattle >24 months were the most common CHMAs.
