Linear regression of calf body weight (BW) from March birth to November weaning. Calves were born to dams that conceived either by artificial insemination (AI) or natural service (NS). Cow–calf pairs grazed either subirrigated meadow (MDW) or upland range (RNG) from June 1 to weaning. No difference in calf birth BW was observed (P ≥ 0.13) until weaning (*P < 0.01).
