• Abstract

  Based on discussions with producers, researchers and a careful literature review, the objective of this research was defined to determine the ideal profile of amino acids for male and female broiler breeders in the phases of growth and reproduction. The amino acids studied will be lysine (Lys), methionine+cysteine (Met+Cys), threonine (Thr), tryptophan (Trp), valine (Val), isoleucine (Ile…

• Abstract

  The In order to elaborate this proposal, a bibliography was carried out on sources and requirements of tryptophan for brown laying hens in the last six decades. Based on the reviewed studies, at least three findings were made, the first being in relation to the sources used in the studies, which used a single source of tryptophan, l-tryptophan 98%. The second is in relation to the use of …

• Abstract

  The objective of this research is to analyze the coefficients that represent the partition of energy ingested by Japanese quails for maintenance and egg production. An assay will be carried out to evaluate the responses of egg mass (EM) and body weight (BW) of Japanese quails submitted to different intakes of metabolizable energy (MEI). 70 Japanese quails will be used, receiving levels of…

• Abstract

  Based on the ideal protein concept, accurate estimation of Lys intake is essential for the correction of other essential amino acids in dietary protein. Until the present moment, no scientific publication was found the requirement of Lys for Japanese quail breeding females. The lack of this information limits actions in the nutritional management of these birds, especially in the current …
