Effect of road transport for up to 24 hours followed by twenty-four hour recovery on live weight and physiological responses of bulls

Table 4 Treatment means (n = 12 animals per treatment) with SE¹ for plasma albumin, globulin and total protein pre (-0.25 h) and post-transport (0, 1, 2, 4, 6, 8, 12 and 24 h).

Control = J 0 not transported; animals transported for journey (J) durations of 6, 9, 12, 18 and 24 hours (h) by road at a stocking density of 1.02 m² per animal. ^a,b,within a row, means differ from pre-transport baseline (-0.25 h pre-transport) at P < 0.05. ¹Standard error (SE). ²Effect of time (exact P value).
