However, there were three SNPs associated with serum IgG concentration, three SNPs associated with serum albumin concentration, four SNPs associated with serum total protein content, three SNPs associated with globulin concentration, two SNPs associated with specific gravity, five SNPs associated with total solids percentage from a Brix refractometer, three SNPs associated with incidents of pneumonia and two SNPs associated with diarrhoea occurrence, which were suggestively significant (P < 5 × 10−5) (Table 3). Here, ALB is linked to susceptibility to pneumonia measurement.
