Sampling dates occurred prior to lambing (prelambing), after lambing (postlambing), and at weaning.

¹Treatments were not supplemented (CON−), a pelleted supplement only (CON+), CON+ with a seaweed extract (SWO), and CON+ with a seaweed plus terrestrial plant extract (SWP).

²Orthogonal contrasts tested were SWO vs. SWP = differences in the extracts used (SWO compared with SWP), eff. of extract (CON+ compared with SWO and SWP), and eff. of supp. = effect of supplements (CON− compared with CON+, SWO, and SWP).

³PU = plasma urea.

⁴Experimental unit was the replicated pastures.
