This study aimed to systematically review the literature of the last 24 years to determine the influence of dam heat stress, nutrition, body condition, vaccination, parity, and twin pregnancy on calf morbidity and mortality. The systematic search was carried out using PubMed, CAB Abstracts, and Web of Science databases. The final number of included studies was 11 for heat stress, 21 for nutrition, 11 for body condition, 11 for vaccination, 23 for parity, and 18 for twin pregnancy. The body condition score, parity, and twin pregnancy had an influence on perinatal mortality. Vaccination, parity, and twin pregnancy had an influence on mortality up to weaning. Heat stress, nutrition, and twin pregnancy had an influence on the immunoglobulin transfer to the calves. Nutrition, body condition score, vaccination, and parity had an influence on morbidity. This systematic review provides evidence that prenatal factors have an influence on calf morbidity and mortality.
本研究旨在系统回顾过去24年的文献，以确定奶牛热应激、营养、体况、疫苗接种、胎次和双胎妊娠对犊牛发病率和死亡率的影响。使用PubMed、CAB文摘和科学网数据库进行了系统检索。纳入研究的最终数量为：热应激方面11项，营养方面21项，体况方面11项，疫苗接种方面11项，胎次方面23项，双胎妊娠方面18项。体况评分、胎次和双胎妊娠对围产期死亡率有影响。疫苗接种、胎次和双胎妊娠对断奶前死亡率有影响。热应激、营养和双胎妊娠对犊牛的免疫球蛋白转移有影响。营养、体况评分、疫苗接种和胎次对发病率有影响。本系统综述提供了证据，表明产前因素对犊牛发病率和死亡率有影响。
