摘要

本章考察了早期生活扰动对发育中的小牛的作用。令人惊讶的是，我们观察到对性发育和精子质量的影响，包括精子形态，早在受孕期（受孕后-60至23天）。同样，在出生后（6个月前），饮食紊乱会延缓性发育和精子质量。在这里，我们讨论了发展的本体论，并研究了为什么这些发展时期是公牛生育的基础。最终，这导致了对当前畜牧业协议的修改建议。

Prenatal and Preweaning Environmental Effects upon Pubertal Development and Sperm Production.

This chapter examines the role of early life perturbations upon the developing bull calf. Surprisingly, we observe effects upon sexual development and sperm quality, including sperm morphology, as early as the periconception period (-60 to 23 days post conception). Similarly, during postnatal life (prior to 6mths of age) dietary perturbations retard sexual development and sperm quality. Herein we discuss the ontology of development and examine why these periods of development are fundamental to fertility in the bull. Ultimately, this leads to recommendations for changes to current husbandry protocols.

期刊介绍： "Advances in Anatomy, Embryology and Cell Biology" presents critical reviews on all topical fields of normal and experimental anatomy including cell biology. The multi-perspective presentation of morphological aspects of basic biological phenomen in the human constitutes the main focus of the series. The contributions re-evaluate the latest findings and show ways for further research.
