Fig. 3From: Variations in porcine colostrum oligosaccharide composition between breeds and in association with sow maternal performanceDistribution of colostrum samples stratified by breed (a), season1 (b) and parity number2 (c) to oligosaccharide (OS) clusters3,4. 1The season was assigned as follows: 1 = if the parturition was included in the period between the 1st of December and the 28th of February; 2 = between the 1st of March and the 31st of May; 3 = between the 1st of June and the 31st of August; 4 = between the 1st of September and the 30th of November. 2 Class of parity number were defined as 1 for parity number from 1 to 3 and as 2 for parity number ≥ 4. 3Clusters were formed using the first 7 principal components (which explained 78% of the total OS variability and had eigenvalues for components > 0.8), considering the 16 mostly represented OS (those in Table 2 plus 2_0_1_0_0; 3_2_0_0_0; 4_0_0_0_0; 4_1_1_0_0). 4 Total number of samples in each clusterBack to article page
