The average annual number of pigs moved, grouped by age and sex
categories were 71,606 (2.03%) sows, 26,606 (0.76%) boars, 1.37
million gilts (38.70%), 1.60 million barrows (45.37%), 258,290 male
piglets (7.31%) and 206,223 female piglets (5.83%), the average
considered only 2018 and 2019.
The number of movements (110,932) in Figure 1A is related to the number
of animals (474,116) in Fig. 1B. In contrast, when analysing the
industrial premises, the relation is inverted, and few movements (3,379)
in Fig. 1A account for the higher number of animals (875,232) in Fig.
1B. The number of animals transported by the industrials, which averages
51.99 pigs per movement, clearly explains this observation, which
contrasts with an average of 5.94 pigs in the other type of premises.
