Relações treonina:lisina digestíveis para suínos na fase inicial, alimentados com rações de baixa proteína, calculadas de acordo com o conceito de energia líquida Digestible threonine:lysine ratios for starting pigs fed low protein diets, considering net energy concept

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2009
Foram realizados dois experimentos com o objetivo de estudar, no primeiro, o efeito de diferentes relações treonina:lisina digestíveis (TL) sobre a utilização do nitrogênio (N) em suínos na fase inicial, dos 15 aos 30kg de peso, e, no segundo, o efeito ...

Evaluation of nutrient excretion and retention in broilers submitted to different nutritional strategies

open access: yesBrazilian Journal of Poultry Science, 2013
An experiment was carried out to evaluate the effects of different nutritional strategies on nitrogen (N), phosphorus (P) and calcium (Ca) balance and on copper (Cu), manganese (Mn) and zinc (Zn) excretion in broilers during the periods of 1 to 21 days ...

Cohort study of the association of antibody levels to AMA1, MSP119, MSP3 and GLURP with protection from clinical malaria in Ghanaian children. [PDF]

open access: yes, 2008
BACKGROUND: Antigen-specific antibody-mediated immune responses play an important role in natural protection against clinical malaria, but conflicting estimates of this association have emerged from immuno-epidemiological studies in different ...

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 ...

Estimation of the dietary essential amino acid requirements of colliroja Astyanax fasciatus by using the ideal protein concept

open access: yes, 2015
Colliroja, Astyanax fasciatus, is a new aquaculture species, and information on its dietary essential amino acid requirements is lacking. The whole body composition of 120 farmed fish (16.2 ± 8.8 g) was determined to estimate the dietary essential amino ...

Carcass characteristics of broilers at 42 days receiving diets with phytase in different energy and crude protein levels Características de carcaça de frangos aos 42 dias recebendo rações com fitase em diferentes níveis energéticos e de proteína bruta

open access: yesCiência e Agrotecnologia, 2011
The aim of this study was to evaluate carcass characteristics and quality of breast meat after the inclusion of phytase in broiler diets with different levels of apparent metabolizable energy (AMEn) corrected for nitrogen and reduced crude protein (CP ...

Modeling of tertiary and quaternary protein structures by homology [PDF]

open access: yes, 2012
The structure of a protein is crucial to understand its function. Despite this importance, experimentally solved structures are only available for a small portion of the currently known protein sequences.

Performance and carcass characteristics of Cobb × Cobb 500 slow-feathering male broilers fed on dietary programs having stepwise increases in ideal protein density

open access: yes, 2012
SUMMARY The Cobb × Cobb 500 slow-feathering male is a fast early-growth broiler grown under variable feeding programs and amino acid (AA) densities. An experiment was conducted using diets with increased ideal protein densities in a feeding program of 1 ...
