摘要

营养策略对初乳品质和产量的影响受母猪初乳生产能力、胎次、诱导产犊方案和妊娠期长短的影响。最大限度地提高初乳产量和质量的最大机会是通过适当管理妊娠期的身体状况，使母猪在分娩时不处于负能量平衡状态。饲粮中添加脂肪或油可提高初乳总脂肪率。初乳脂肪酸组成也可以通过添加饲料油或增加支链氨基酸来改变。初乳蛋白和免疫球蛋白更难影响。

Feeding strategies to increase sow colostrum quality and yield

Effects of nutritional strategies on colostrum quality and yield are variable as influenced by sow colostrum production capacity, parity, farrowing induction protocol, and gestation length. The greatest opportunity to maximize colostrum yield and quality is through proper management of body condition in gestation such that sows are not in a negative energy balance when entering farrowing. Total colostrum fat percentage can be increased through the addition of dietary fat or oil. Colostrum fatty acid composition can also be changed by addition of dietary oil or increased branched chain amino acids. Colostrum protein and immunoglobulins are more challenging to influence.

期刊介绍： The Journal of Swine Health & Production (JSHAP) is an open-access and peer-reviewed journal published by the American Association of Swine Veterinarians (AASV) since 1993. The aim of the journal is the timely publication of peer-reviewed papers with a scope that encompasses the many domains of applied swine health and production, including the diagnosis, treatment, management, prevention and eradication of swine diseases, welfare & behavior, nutrition, public health, epidemiology, food safety, biosecurity, pharmaceuticals, antimicrobial use and resistance, reproduction, growth, systems flow, economics, and facility design. The journal provides a platform for researchers, veterinary practitioners, academics, and students to share their work with an international audience. The journal publishes information that contains an applied and practical focus and presents scientific information that is accessible to the busy veterinary practitioner as well as to the research and academic community. Hence, manuscripts with an applied focus are considered for publication, and the journal publishes original research, brief communications, case reports/series, literature reviews, commentaries, diagnostic notes, production tools, and practice tips. All manuscripts submitted to the Journal of Swine Health & Production are peer-reviewed.
