Meloxicam alters arachidonic acid relationships with baseline haptoglobin and type of rearing. a The treatment × haptoglobin covariate interaction (P = 0.01) for plasma arachidonic acid (ArA) concentration in control ewes (CON) and ewes treated with 90 mg meloxicam (MEL) on d 1 and 4 after lambing. D 4 ArA concentrations was dependent on d 1 haptoglobin concentrations (inflammation marker), with greater initial haptoglobin related to greater ArA in control ewes, but lesser ArA in ewes receiving MEL. D 4 ArA = 7.02–3.87 × covariate + 0.70 × covariate2–5.41[control] + 3.85 × covariate[control] – 0.77 × covariate2[control]. Shaded areas represent 95% confidence intervals; slopes differ at P = 0.01. b D 4 plasma ArA was less in control ewes rearing single lambs compared to MEL ewes rearing either single lambs or twins and control ewes rearing twins (Trt × lambs: P < 0.001)
