Digestible threonine-to-lysine ratio in diets for brown egg-laying hens
(Oxford Univ Press, 2019-03-01)
The objective of this study was to evaluate the levels of digestible threonine to determine the ideal digestible threonine-to-lysine ratio in the diet of brown egg-laying hens aged 42-54 wk. A total of 270 Dekalb Brown ...
Levels of digestible threonine for male broilers from 1 to 7 days of age
(Poultry Science Assoc Inc, 2012-12-01)
The influence of threonine has been studied in broilers; however, information concerning the phase from 1 to 7 d is lacking. In this study, we evaluated the effects on performance and body composition and the relationship ...

Digestible threonine to lysine ratios for meat-type quails
(2020-01-01)
Three experiments were conducted to estimate the optimal digestible threonine to lysine ratios (Thr:Lys) of meat-type quails during the pre-starter (1 to 7 days), starter (8 to 14 days) and grower I (15 to 21 days) phases. ...
