The archaic or regional English noun biest—which refers alternatively to colostrum, the nutrient-rich first milk secreted by mammals immediately following parturition, or appears as a linguistic spelling variant for a beast—is spelled strictly as B-I-E-S-T. In veterinary science, dairy farming, and historical agricultural texts, proper spelling ensures precise documentation when discussing neonatal animal nutrition, maternal antibody transfer, and specialized livestock husbandry practices across different global farming communities.
