A Case of Bacterial Postpartum Metritis in a 4-Year Old Duroc Sow

The attention of the Animal Health team of Swine Research Unit of Swine and Rabbit Research Programme of National Animal Production Research Institute (NAPRI) was drawn to a farrowing pen with a complaint of pus discharge from the vulva of a Duroc sow which farrowed 9 piglets 10 days earlier. Microbiological survey identified the presence of Escherichia coli, Staphylococcus and Proteus species from the sterile vaginal swab was taken from the sow. Antibiogram revealed the susceptibility of the three identified bacteria to ofloxacin, streptomycin and gentamicin in the order of increasing susceptibility. Staphylococcus species was also found to be susceptible to ciprofloxacin while Proteus species was susceptible to augmentin® and chloramphenicol. All the three species of bacteria were resistant to nitrofuratoin, rocephin® and ampiclox®. The sow was treated with deep intramuscular administration of streptomycin at 20 mg/kg once daily for 5 days and 10 IU of oxytocin once daily for 2 days. There was expulsion of macerated feotus about 24 hours following administration of the last dose of oxytocin and the macerated feotus was properly disposed and the entire pen was cleaned and disinfected. The vulva was noticed to be completely devoid of the mucous discharges after the course of the antibiotic regimen.Key words: Metritis, Postpartum, Duroc, Sow, NAPRI

Fertility Parameters in Crossbred Sows Treated with Cloprostenol Sodium (Synchromate®) in Zaria, Nigeria

This study was carried out to evaluate fertility parameters in crossbred sows in Zaria, following treatment with Cloprostenol sodium (Synchromate®). Ten (n = 10) apparently healthy crossbred sows were randomly assigned to two equal treatment groups based on number of injections of 500μg Synchromate®. Group 1 received two injections on days 0 and 13, while Group 2 received three injections on days 0, 7 and 13. Oestrus was monitored visually for signs of oestrus twice daily from 0700 – 1000h and 1500 – 1800h. The fertility parameters evaluated were: oestrus response rate (ORR), time to onset of oestrus (TOO), duration of oestrus (DOO), conception rate (CR), pregnancy rate (PR), farrowing rate (FR) and litter size (LS). Data on ORR, CR, PR and FR were expressed in percentages while TOO, DOO and LS were expressed as mean ± SEM. Student t-test and Tukey’s post-hoc test were used to compare the percentages and mean values between the groups. The Graphpad Prism® data package was used for statistical analysis and values of P<0.05 were considered significant. Fertility parameters TOO, DOO, LS, ORR, CR, PR, FR for Group 1 (187.20 ± 8.98h, 87.60 ± 4.49h, 7.25 ± 1.44, 100 %, 60 %, 80 % and 100 % respectively) and Group 2 (176.00 ± 40.00h, 86.60 ± 13.36h, 7.50 ± 1.50, 60 %, 100 %, 80 % and 66.67 % respectively). The differences in fertility parameters between the groups were not statistically significant. It is recommended therefore that double injections of cloprostenol sodium (Synchromate®) should be used for oestrus synchronization as it increases fertility parameters in cross bred sows at 13 days apart.Key words: Fertility parameters, crossbred sows, cloprostenol sodium, Zaria
