Waste Milk from Antibiotic Treated Cows as Feed for Young Calves

Risk factors for neonatal calf diarrhoea and enteropathogen shedding in New Zealand dairy farms

“…According to the responses to the questionnaire, most waste milk originated from cows affected with mastitis or treated with antibiotics (data not shown). Comparable results have been reported previously (Chardavoyne et al, 1979). The potential benefits of the administration of waste milk should, however, be assessed in specifically designed prospective studies, Table 3 Variables independently associated with liquid faeces with P < 0.5 in the final logistic regression models with random farm effect.…”

Selective degradation of tetracycline antibiotics present in raw milk by electrochemical method

“…During the withdrawal period, the milk from cows that have been treated with an antibiotic must be withheld from sale. This waste milk represents an economic loss and causes disposal problems [5]. The feeding of milk with antibiotic residues to calves is prohibited because it has been reported that antibiotic-containing milk has poor palatability and is often rejected by calves, slows the growth rates of the calves, their antibiotics may select for resistance in the calves' enteric flora, and increases the risk of disease [2,6].…”

Tissue disposition and depletion of penicillin G after oral administration with milk in unweaned dairy calves

“…[1][2][3][4][5] Any use of antimicrobials in veal calves requires consideration of the fact that calves are commonly processed within 12 hours of marketing. 7 Because this "waste" milk often contains antimicrobials, [7][8][9] producers may unintentionally and unknowingly cause tissue drug residues when feeding calves waste milk. 7 Because this "waste" milk often contains antimicrobials, [7][8][9] producers may unintentionally and unknowingly cause tissue drug residues when feeding calves waste milk.…”
