Coping with seasonal infertility in the sow herd.
By NCSU Extension Swine Husbandry specialists. During summer and early fall, many sow farms experience a variety of reproductive problems. These problems can be, but are not limited to, anestrus, extended or no weaning-to-estrus intervals, poor conception rates, and higher embryo mortality rates (low farrowing rates).This phenomenon is commonly referred to as "seasonal infertility" and can also be present in boar studs, where the result is lower semen output and lower semen quality.

The second article offers specific management strategies to combat the heat stress problems discussed in the above article.
