The aim of this study was to investigate the effects of metabolic diseases on uterine involution and reproductive performance during the postpartum period. Multiparous Holstein dairy cows ( = 50) were divided into four groups based on whether they were healthy ( = 14), or had lipomobilization ( = 14), hypocalcemia ( = 11), and hyperketonemia ( = 11). Transrectal palpation and transrectal B-Mode sonography were carried out on days 7, 14, 21, 30, 45 and 60 after parturition. Cows with metabolic disease had a greater ( < 0.05) uterine size as assessed transrectally compared with cows without metabolic disease. Sonographic measurements revealed a greater ( < 0.05) horn diameter and endometrial thickness in cows of the metabolic disease groups than in the healthy cows. Metabolic disease affected ( < 0.05) the milk yield, percentage of service per pregnancy, days to first ovulation and days open. In conclusion, metabolic disease affected the uterine involution and fertility during the postpartum period.
本研究的目的是调查代谢疾病对产后子宫复旧和繁殖性能的影响。将经产荷斯坦奶牛（n = 50）根据其是否健康（n = 14）、是否有脂肪动员（n = 14）、低钙血症（n = 11）和高酮血症（n = 11）分为四组。在分娩后第7、14、21、30、45和60天进行经直肠触诊和经直肠B型超声检查。与无代谢疾病的奶牛相比，经直肠评估发现患有代谢疾病的奶牛子宫尺寸更大（P < 0.05）。超声测量显示，代谢疾病组奶牛的子宫角直径和子宫内膜厚度比健康奶牛更大（P < 0.05）。代谢疾病影响（P < 0.05）产奶量、每次妊娠配种百分比、首次排卵天数和空怀天数。总之，代谢疾病影响产后子宫复旧和生育能力。
