Levels of digestible lysine for free-range chicken of the Caneludo Catolé from 1 to 105 days of age

“…This can be explained by the use of isoenergetic diets, since poultry normally regule the feed intake primarily to satisfy energetic demands (Bertechini, 2006); however, there was an increasing linear effect (P<0.01) for digestible lysine, regule the intake (Ŷ = 1423x -0.014; r 2 = 0.98) ( Table 4). The lack of significant effect on feed intake has been reported for fast-growing chicken by Bernal et al (2014) when evaluating five levels of Research, Society and Development, v. 9, n. 7, e706974717, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i7.4717 digestible lysine (1.06 to 1.30%) for Cobb 500 broilers from 10 to 22 days of age. In addition, Dias (2015) evaluated four levels of digestible lysine, between 1.016 and 1.265%, for Cobb 500 broilers in the period from 8 to 21 days of age, and did not observe an effect on feed intake, corroborating with the present study.…”
