Infectious Causes of Infertility in Sows (1993)
Metadata[+] Show full item record
Any time a sow farrows prematurely, there is the fear that additional litters will be lost. An abortion rate of less than 2 percent is considered an acceptable level in most herds. Premature farrowing usually results from nutritional, genetic or environmental stresses, but the exact cause is often unknown. This publication addresses several infectious causes of infertility and abortion in sows along with some preventive measures.
