A total of 1,200 pigs were used to determine
whether dietary lysine level fed in the growing phase influenced the response to
lysine level fed in the finishing phase. Pigs
were fed either an adequate or low lysine level during the growing (60 to 170 lb) and/
or finishing phase (170 to 265 lb). Feeding
a deficient lysine level decreased ADG and
F/G during the phase when the deficient diet
was fed; however, lysine level fed in the
growing phase did not influence the response
in the finishing phase. Carcass parameters
were influenced more by the lysine level fed
in the finishing diets.
