Abstract:
The decision on whether to treat cows’ subclinical udder infections or to ignore it is not straightforward as antibiotic treatment of animals that are not at risk should be justified with respect to the cost of treatment and milk loss. Data regarding 152 dairy cows was used to evaluate the economics of mastitis-control according to five categories: a) No intervention; b) Antibiotic treatment; c) Drying off quarter/s; d) Drying-off the whole udder and e) Culling. The data was analyzed according to parity, bacteria, time in lactation at infection recording, treatment, time elapsed between infection and treatment and somatic cell count at treatment. Cure of first lactation cows was significantly higher than that of cows at their 2nd and 3rd onward lactations and depended on the bacteria causing the infection. It was higher in cows infected with coagulase negative staphylococci than with various types of Streptococci, and lowest in cows previously infected with Escherichia coli. The effect of day of treatment after onset of the infection was significant. It was also demonstrated that use of casein hydrolysate (a drug in development that can dry-off the inflamed quarter with modest reduction in overall milk yield by avoiding the problem of withholding milk), eliminates the need to use antibiotics and the cost of treatment becomes highly economical. In conclusion, antibiotic treatment is unavoidably associated with milk waste; thus, when the alternative is no intervention it is the preferable option. In cases where the infected gland produces low quality milk with somatic cell count ~1,000×103cells/mL milk, drying-off the gland by using a drug such as casein hydrolysate is the preferable option. © 2017, Israel Veterinary Medical Association.
