Evaluating natural planned exposure protocols on rotavirus shedding patterns in gilts and the impact on their suckling pigs

Objective: The objectives of this study were to determine the pattern rotavirus A (RVA), B (RVB), and C (RVC) shedding in gilts after natural planned exposure (NPE) administration assess effects on piglet weaning weight, preweaning mortality, RV shedding. Materials methods: total 70 pregnant enrolled allocated into 4 groups. Group 1 was given NPE at 5, 4, 3 weeks prefarrowing (WPF); 2 5 WPF; WPF only. (control group) did not receive any NPE. Samples from 46 litters (5 piglets/litter) tested 12 sample times. Piglets sampled weekly 24 hours age until 6 by quantitative reverse transcriptase-polymerase chain reaction for RVA, RVB, RVC. Results: There a significant improvement weight piglets born that received administrations compared fewer or no administrations. Shedding RVA RVB well controlled farrowing room regardless treatment group, but RVC observed as early week old. This conducted single farm, results should be carefully interpreted with knowledge variations farms systems. Implications: Three had valuable production economic benefits producer. Circulation patterns appear correlate; interventions one have value against others.
