Pigs receiving daily tailored diets using precision-feeding techniques have different threonine requirements than pigs fed in conventional phase-feeding systems
(2019-02-22)
Background: There is large variation in amino acids requirements among pigs, hence feeding pigs individually with daily tailored diets or in groups with a single feed may require different levels of nutrients. Thus, the ...
Threonine incorporation in tissues of growing broiler chickens using L-[N-15] threonine
(Wiley-Blackwell, 2021-01-07)
Most amino acid requirement trials appear for whole-body responses, but there is little information concerning amino acid incorporation in individual tissues, which may vary according to the age. L-[N-15] threonine was ...
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 ...
Estimating real time individual lysine and threonine requirements in precision-fed pigs
(Wageningen Acad Publ, 2019-01-01)
This study aimed to estimate independently real-time lysine (Lys) and threonine (Thr) requirements in growing-finishing pigs. Ninety-five pigs were randomly assigned to treatments according to 2x5 factorial arrangement ...
Digestible threonine for slow-growing broilers: performance, carcass characteristics, intestinal mucin, and duodenal morphometry
(Brazilian Journal of Animal Science, 2023)
Exigências de manutenção e eficiência de deposição de lisina e treonina para suínos
(Universidade Federal de Santa MariaBRZootecniaUFSMPrograma de Pós-Graduação em Zootecnia, 2013-02-27)
Two experiments were performed in order to determine the maintenance requirements and marginal efficiency of utilization of the amino acids lysine and threonine, through the nitrogen balance technique. It was used 12 ...
Protease supplementation under amino acid reduction in diets formulated with different nutritional requirements for broilers
(Brazilian Journal of Poultry Science, 2019)
Efeitos de planos nutricionais sobre o desempenho, características de carcaça e custos de produção de frangos de corte
(Universidade Federal de Minas GeraisUFMG, 2013-02-28)
Two trials were conducted in a completely randomized design to investigate effects of nutritional plans on performance, carcass yield and composition, and costs of poultry production, males in trial one, females in trial ...
Protease Supplementation under Amino Acid Reduction in Diets Formulated with Different Nutritional Requirements for Broilers
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2019-01-01)
This study aimed to evaluate the effect of different reductions in digestible amino acids content (lysine, methionine, and threonine), according to two nutritional requirements in corn, soybean meal, and meat and bone meal ...
