A total of 200 Duroc cross (Landrace× Large White) pigs, 50% barrows and 50% gilts, of
26.3±0.55 kg body weight (BW) were used to study the effect of Lysine (Lys) restriction in the …

The expected increase in boar (pig entire male) production while societal concerns for
castration increase requires good estimations of their nutrient requirements. In this work, a …

Two experiments were conducted to develop a simplified dose–response technique to
estimate the Lys requirement of individual, meal-fed growing pigs. In Exp. 1, we studied …

An experiment with 2 trials (28 d/trial) was conducted to determine body composition, tissue
deposition, and utilization of Lys for protein deposition (PD) of barrows and gilts fed L-Lys …

There is large variation in the production performance of commercial growing-finishing pig
farms. This variation even exists when pigs have a similar genetic background and fed …

ABSTRACT A nitrogen balance test was performed to evaluate the individual responses of
growing pigs to threonine intake. Eight commercial barrows were used (body weight ranging …

Two nitrogen balance (NB) studies were performed to estimate individual responses and the
ideal standardized ileal digestible (SID) of valine (Val) and isoleucine (Ile) to lysine (Lys) …

Résumé Chez le porc en croissance, la connaissance des besoins nutritionnels, notamment
en acides aminés, est nécessaire pour formuler des aliments permettant d'optimiser …

The aim of this study was to compare the digestible lysine requirements of castrated and
immunocastrated pigs, generated via three factorial methods based on the performance of …
