Effects of nutrient supplementation on pig sickness behavior when infected with Porcine Reproductive and Respiratory Syndrome virus

Porcine Reproductive and Respiratory Syndrome virus (PRRSV) is a significant respiratory pathogen in grow-finish pigs. The objective of this research was to investigate how nutrient supplements impact pig sickness behavior during a PRRSV infection. Sixty pigs were inoculated intranasal and I.M. with PRRSV at 35 kg bodyweight and began treatment supplements. Treatments included no nutrient supplement, water supplement, and water+feed supplement. Pig home-pen behavior was video recorded on -1, 3, 6, 9, 12, 15, and 18 days post inoculation. Observations were recorded using 10-minute scan sampling from 7:00-19:00 hours by one observer. Percent of pigs standing, lying, sitting, eating, and drinking within each pen was recorded. Pigs given the water+feed supplement showed an increase in sitting behavior compared to the control and water supplement treatments (P≤0.05); however, no other differences were observed (P>0.05). Therefore, the nutrient supplement treatments had minimal effect on sickness behaviors of PRRSV infected pigs.
