Abstract

This case study characterizes breeding performance related to unintentional dietary intake of phytoestrogenic compounds. Breeder farms A (affected) and B (unaffected) were under single management and supplied by two unconnected feed mills. Breeding parameters were recorded over 2 years and feed analyzed for mycotoxins and isoflavonoids. Farm B had consistently better breeding performance. Clinical signs of hyperestrogenism (vulval tumefaction, mammary gland dysfunction, and delayed estrus) were evident in 5% to 10% of breeding females on farm A. Mycotoxin concentrations were negligible, but phytoestrogenic isoflavonoid concentrations associated with one source of soybean meal were above 55,000 µg/kg on farm A.

临床雌激素水平升高与无意摄入植物雌激素大豆有关

本案例研究的特点是与无意中摄入植物雌激素化合物有关的育种性能。饲养场A(受影响)和B(未受影响)采用单一管理，由两个不相连的饲料厂供应。记录了2年的饲养参数，并分析了饲料中的霉菌毒素和异黄酮。农场B的育种性能一直较好。在A农场，5% - 10%的繁殖雌性有明显的雌激素分泌亢进的临床症状(外阴肿胀、乳腺功能障碍和发情延迟)。霉菌毒素浓度可以忽略不计，但在A农场，与一种豆粕来源相关的植物雌激素异黄酮浓度高于55,000µg/kg。

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.
