Effects of lysine levels on performance, blood parameters, and nutrient digestibility of Duroc barrows in the starter phase.

The objective of this study was to evaluate the effects of different levels of digestible lysine, at fixed amino acid ratios, in performance, blood parameters and diet digestibility of barrows from 15 to 30 kg. Fifty barrows of the Duroc breed with an average initial body weight of 14.95±3.
