How do daily temperature fluctuations impact breeding sows?

A team of Spanish researchers evaluated the impact of circadian rhythm of temperature in breeding sows’ reproduction during the oestrus period. They published their findings in Porcine Health Management. The circadian rhythm controls a variety of physiological events in pigs and is determined by their body temperature. Body temperature is subject to variation throughout the day. Data collection The researchers used 85 sows for this trial. The team determined the onset of oestrous in
