¹Weekly amount of LFAT and HFAT supplements was divided into three equal amounts and offered every Monday, Wednesday, and Friday. Cows calved their first offspring on average on day 89 ± 5. All pastures were offered free choice access to limpograss hay and supplemented with sugarcane molasses + urea (12 kg DM per cow per week) from days 110 to 236.
