Abstract: RESUMO Este estudo foi realizado para determinar a relação ideal de treonina:lisina digestíveis para poedeiras leves no período de 42 a 58 semanas de idade. Foram utilizadas 240 poedeiras Hy Line W-36 com 42 semanas de idade durante 16 semanas. Os tratamentos foram distribuídos em delineamento inteiramente casualizado, com oito repetições e seis aves por unidade experimental. As dietas experimentais foram formuladas com cinco níveis de treonina digestível (0,461; 0,515; 0,569; 0,622 e 0,676%) proporcionando as… Show more

“…Digestible lysine levels in grower diet did not influence (p>0.05) the percentages of egg components (albumen and yolk), albumen and yolk indexes and Haugh unit (Table 7). These results are in agreement with those presented by Pastore et al (2016), Santos et al (2014), Figueiredo et al (2012) and Jardim Filho et al (2010). Nevertheless, lysine is an essential amino acid in the structure of egg components.…”

“…Due to the precocity and high peak production of commercial layers, it is necessary to reassess such animals' nutritional needs to guarantee maximum performance. However, these birds require the supply of nutrients in adequate amounts, including amino acids, to produce eggs at levels compatible with their genetic potency (Pastore et al, 2016;Chrystal et al, 2020).…”

“…Due to the commercial availability of synthetic amino acids at compatible prices, there is currently an increasing practice of incorporating these amino acids in diets, allowing formulations of minimum cost with crude protein levels lower than those recommended in the tables of nutritional requirements, but meeting the requirements in essential amino acids (Star et al, 2021). Threonine is an essential amino acid for birds, considered the third limiting amino acid in diets for laying hens (Pastore et al, 2016). The ratio of 76% digestible lysine for light laying hens with 51g egg mass is recommended (Rostagno et al, 2011).…”
