Suspect reproductive disorders in sows should:
- deterioration of herd reproductive parameters: decreased percentage of fertilization and farrowing; increased number of over-fertilization (return to hunt; procholosity);
- сhanges in production parameters: decrease in the size of nests; increase in the number of stillbirths;
- appearance of pathological signs: increase in the number of mummified piglets; abortions; vaginal discharge, etc.
Often these problems may not be accompanied by obvious pathological changes that would directly indicate reproductive disorders, but their negative impact on the productivity of the flock will be significant.
At detection of what signs one should "sound the alarm", what diagnostic methods to choose for the best result and how to take reproductive infectious disorders in sows under control read the column "For the veterinarian" in the December issue of "Profitable Pig Production".
