Digestible isoleucine requirements for 22- and 42-day-old broilers

open access: yesActa Scientiarum: Animal Sciences, 2015
Current experiment established different criteria to evaluate the requirements of digestible isoleucine for 22- and 42-day-old broilers by different regression models (quadratic, exponential and Linear Response Plateau) and, in the case of statistical ...

Chemical reaction systems with toric steady states [PDF]

open access: yes, 2011
Mass-action chemical reaction systems are frequently used in Computational Biology. The corresponding polynomial dynamical systems are often large (consisting of tens or even hundreds of ordinary differential equations) and poorly parametrized (due to ...

Diets formulated on total or digestible amino acid basis with different energy levels and physical form on broiler performance

open access: yesBrazilian Journal of Poultry Science, 2005
We studied the effects of two different systems of expressing amino acid requirements (total - TAA or digestible - DAA), two energy levels (2,900 or 3,200 kcal of ME/kg) and two physical forms (mash or pellet) on the performance of male broilers from 21 ...

Discovery of Stable and Selective Antibody Mimetics from Combinatorial Libraries of Polyvalent, Loop-Functionalized Peptoid Nanosheets. [PDF]

open access: yes, 2019
The ability of antibodies to bind a wide variety of analytes with high specificity and high affinity makes them ideal candidates for therapeutic and diagnostic applications. However, the poor stability and high production cost of antibodies have prompted

Effects of amino acid levels during rearing on Cobb 500 slow-feathering broiler breeders: 1. Growth and development

open access: yesPoultry Science, 2021
: Adequate pullet nutrition is essential to reach BW and suitable body composition for reproduction. An experiment was conducted to determine the effects of 4 dietary amino acid (AA) levels on BW, flock uniformity, body conformation, organ, leg, and ...

Ultrafast electron diffraction using an ultracold source [PDF]

open access: yes, 2014
We present diffraction patterns from micron-sized areas of mono-crystalline graphite obtained with an ultracold and ultrafast electron source. We show that high spatial coherence is manifest in the visibility of the patterns even for picosecond bunches ...

Digestible lysine levels obtained by two methods of formulation of diets for 22-to-42-day-old broilers

open access: yesRevista Brasileira de Zootecnia, 2014
The objective of this study was to evaluate the effect of digestible lysine levels in diets with or without supplementation of industrial amino acids on performance, carcass characteristics and nitrogen excretion in broilers of 22 to 42 days of age ...

Diets with reduced levels of nutrients supplemented with phytase and amino acids for broilers Dietas com reduzidos níveis de nutrientes, suplementadas com fitase e aminoácidos, para frangos de corte

open access: yesCiência e Agrotecnologia, 2012
One performance experiment and another metabolism experiment were conducted simultaneously with broilers from 22 to 35 days of age, evaluating five diets in six replicates. The control diet, without phytase, contained 19% of crude protein (CP); 0.412% of
