Dietary lysine-to-energy ratios for managing growth and pubertal development in replacement gilts

Applied Animal Science, 36(5), 701–714.

By: C. Lents *, C. Supakorn*, A. DeDecker, C. Phillips, R. Boyd n, J. Vallet *, G. Rohrer *, G. Foxcroft* ...

author keywords: gilt; growth; puberty; diet; lysine
topics (OpenAlex): Animal Behavior and Welfare Studies; Effects of Environmental Stressors on Livestock; Reproductive Physiology in Livestock
TL;DR: Reducing SID lysine–to–ME ratios in gilt diets can increase the number of gilts within optimal BW range at first estrus, but overall pubertal development is delayed if ratios are reduced below 2.8 and 2.1 g in grower and finisher diets, respectively. (via Semantic Scholar)
