UTI (Urinary tract infections)
The percentage of sows suffering from UTI in the EU is between 22% and 40%. During gestation, the percentage of sows with UTI increases from 7% to 18.2%.
The proportion of sow deaths attributable to cystitis/pyelonephritis varies from 10% to over 40%.
E.coli is the most common pathogen of UTI and the amount of UTI based on E.coli is about 75%.

MMA in Sows – Mastitis-Metritis-Agalactia Syndrome
Mastitis-metritis-agalactia syndrome (MMA) or postpartum dysgalactia syndrome (PPDS) is a disease of multiple etiology and has close links with coliform mastitis and cystitis in sows. Multiple pathogens can be involved in the disease such as E.coli, Klebsiella spp., Enetrobacter spp., Mycoplasma spp. as well as Streptococci and Staphylococci. Other etiological factors are related to endotoxins produced by, for example, E. coli, subclinical endometritis, retarded lactogenesis, hormonal imbalance, teat malformation, and stress. Low fiber diet, fatness at farrowing, and confinement have been found to be risk factors for sows.
MMA syndrome can threaten the lives of both the sow and the piglets. MMA syndrome occurs mostly within the first 48 hours after farrowing, but can also appear within the first week after farrowing.
MMA syndrome requires rapid intervention to save the life and the future productivity of the sow as well as the lives of the piglets. Due to its high efficacy and rapid bactericidal effect, Baytril® offers excellent therapeutic opportunities for MMA syndrome. In different trials, Baytril® was shown to be highly effective against the consequences of MMA Syndrome in metaphylactic as well as in therapeutic use.
In one study, 828 sows were randomly divided in three groups which received the following:
Group 1 served as untreated controls.
Group 2 received 2.5 mg/kg bw enrofloxacin (Baytril®) by i.m. injection immediately after farrowing.
Group 3 received 5 mg/kg bw enrofloxacin (Baytril®) by i.m. injection immediately after farrowing.
The results showed a lower incidence of fever after farrowing, a lower incidence of elevated milk pH (above 6.7), and lower piglet mortality in the groups treated with Baytril®.
