The effects of feeding levels of tryptophan on performance and stress of Japanese quails (Coturnix coturnix japonica) in the rearing and laying periods were evaluated. In the rearing phase, from 30 to 44 days old, 192 Japanese quails were lodged to cages and allotted to completely randomized blocks design, with four nutrition plans [0.27% (control) 0.52; 0.77 and 1.02% of tryptophan] with six replicates and eight birds per cage. Performance (feed intake, body average weight gain, feed conversion ratio), mortality […]
