Subknots in ideal knots, random knots and knotted proteins [PDF]

open access: yesScientific Reports, 2015
AbstractWe introduce disk matrices which encode the knotting of all subchains in circular knot configurations. The disk matrices allow us to dissect circular knots into their subknots, i.e. knot types formed by subchains of the global knot. The identification of subknots is based on the study of linear chains in which a knot type is associated to the ...

How Does Protein Nutrition Affect the Epigenetic Changes in Pig? A Review

open access: yesAnimals, 2021
Epigenetic changes regulate gene expression and depend of external factors, such as environment and nutrition. In pigs, several studies on protein nutrition have been performed to improve productive and reproductive traits.

Digestible lysine levels in semi-heavy laying hens in the period from 28 to 44 weeks of age

open access: yesActa Scientiarum: Animal Sciences, 2014
This study aimed to evaluate the performance of laying hens subjected to heavy semi-low crude protein (14.0%) and lysine levels while maintaining the same relation of digestible amino acid/ digestible lysine.

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

Digestible lysine levels for laying hens and their effects on egg quality

open access: yesActa Scientiarum: Animal Sciences, 2014
Egg quality of semi-heavy laying hens fed on low protein diets (14.0% CP) and on different lysine levels is evaluated, while maintaining the same ratio of digestible amino acids / digestible lysine.

Redução do nível de proteína bruta da ração com suplementação de aminoácidos sintéticos para leitões na fase inicial Effects of reducing dietary crude protein levels for piglets supplemented with synthetic amino acid

open access: yesRevista Brasileira de Zootecnia, 2006
Avaliou-se o efeito da redução do nível de PB e do farelo de soja, com suplementação de aminoácidos, na ração sobre o desempenho, a excreção de N, o peso dos órgãos e a incidência de diarréia em leitões na fase inicial.
