MASTITIS IN SOWS

Sub-clinical infections that don't affect all the glands are
possible during lactation. "Ideally, they should be similarly
treated with intramuscular antibiotics. But they are often not
detected until later when the condition has become chronic
and an antibiotic at this stage would not be effective," said
Webster. In these cases nothing can be done to regain function in the gland and it can mean the sow has to be culled.

Conclusions
Failure to diagnose or treat mastitis can have a significant
effect on a producer's bottom line. Death of the sow and or
the litter is the most obvious loss, but the effect on performance of surviving piglets and sows are not insignificant.
Litters with a poor start in life may take some time to recover
in terms of body weight. Poor development of the gut due to
inadequate milk intake could also affect feed conversion.
Not all infections are preventable, but there are a number
of straightforward management strategies that could help to
reduce the number of cases. Close attention to the sow at farrowing and at weaning is important to spot infections quickly. Maintaining a high standard of hygiene both before and
after farrowing is essential, along with effective fly control. ■
