The objective of this study was to evaluate the total methionine+cystine requirements in function of crushed and ground diets and pullet strain (light and semi-heavy) from 1 to 4 weeks of age. One thousand and sixty 1-day-old pullets were used as follows: 800 Dekalb White pullets and 800 Bovans Goldline pullets, weighting 34.52 ± 0.26 g and 36.41 ± 0.22 g, respectively. The experimental design was completely randomized in a 5 × 2 × 2 factorial scheme (0.65; 0.70; 0.75; […]
