Normalized weight gain of protein-sufficient and -deficient HRV-infected pigs transplanted with sufficient and deficient HIFM (sHIFM/dHIFM) and monitored for 4 weeks. Normalized weight gain of protein-sufficient and -deficient HRV-infected pigs transplanted with sufficient and deficient HIFM (sHIFM/dHIFM) and monitored for 4 weeks. The results are the mean ± SEM from two to four animals of sufficient-diet dHIFM/deficient-diet dHIFM/deficient-diet sHIFM groups, and two or three animals in the sufficient-diet sHIFM group. Statistical analysis was not conducted because of the low animal numbers in some groups. Anastasia N. Vlasova et al. mSphere 2017; doi:10.1128/mSphere.00046-17
