The fetus obtains nutrients directly from the beef cows during late gestation period, and their weight is increasing exponentially. Maternal nutrition supply such as energy, protein, fat, minerals, and vitamins during this period can influence fetus development and subsequent growth of calves after birth. Research suggested that adequate nutrient intake of cows during late gestation period can influence the composition of intestinal microbiota of both beef cows and fetuses, ensuring the health of calves; maintain glycemic homeostasis in its offspring, promoting calves’ growth, and facilitate the differentiation and proliferation of muscle fibroblasts and adipocytes in calves, ultimately leading to an improvement in carcass quality. Clarifying the influence of maternal nutrient intake during late gestation period on its offspring will contribute to the high-quality and efficient production of beef cattle.
