摘要

低蛋白日粮可能会限制日粮中的氮（N）。本研究旨在确定非蛋白氮（NPN）添加量和赖氨酸含量对生长猪生长性能的影响。将围栏饲养的生长猪随机分配到 6 种日粮处理中的一种，以测试 28 天内非蛋白氮添加量和日粮赖氨酸含量的影响。最终体重随赖氨酸含量的增加而增加（P < 0.05），但不受 NPN 的影响（P > 0.05）。磷酸铵可能是猪限氮日粮中一种合适的氮源。

Ammonium phosphate is a potential nitrogen supplement in nitrogen-limiting diets for growing pigs

Reduced protein diets may be limiting in dietary nitrogen (N). The objective of this study was to determine the impact of non-protein nitrogen (NPN) inclusion and lysine content on growth performance of growing pigs. Pen-housed growing pigs were randomly assigned to 1 of 6 dietary treatments to test impact of NPN inclusion and dietary lysine content for 28 d. Non-protein N inclusion increased feed efficiency and lean depth (P < 0.05). Final body weight increased with greater lysine (P < 0.05) but was not impacted by NPN (P > 0.05). Ammonium phosphate may be an appropriate N source in N-limiting diets for pigs.

期刊介绍： Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
