Methionine plus cystine to lysine ratio in diets for tambatinga fingerlings

open access: yesCiência e Agrotecnologia, 2021
Among a variety of hybrids produced in Brazil, tambatinga is obtained from the crossing of a tambaqui female with a pirapitinga male. Although rapid weight gain in less time is an attractive characteristic from a commercial viewpoint, the information on ...

Performance and intestinal responses to dehulling and inclusion level of Australian sweet lupins (Lupinus angustifolius L.) in diets for weaner pigs [PDF]

open access: yes, 2012
A total of 180 entire male weaner pigs weighing 6.4 ± 0.1. kg (mean ± SEM) and housed in pairs was used in a completely randomised block design with 9 dietary treatments (n= 10 pens). Pigs were blocked based on weaning weight.

Effect of amino acid deficiency on precaecal amino acid digestibility in broiler chickens

open access: yesJournal of Animal Physiology and Animal Nutrition, 2019
AbstractIn this study, we determined whether deficient dietary amino acid (AA) concentrations influence the precaecal (pc) AA digestibility when determined using the regression approach. We mixed two basal diets. Basal diet 1 was deficient in essential AAs, whereas adequate AA concentrations were ensured in basal diet 2 by adding free AAs.

THE METABOLISM OF AMINO ACIDS AND CASEIN DIGEST IN PHLORHIZINIZED DOGS [PDF]

open access: yesJournal of Experimental Medicine, 1947
When solutions of sugar-forming amino acids are given parenterally or orally to phlorhizinized dogs, extra sugar and nitrogen are excreted in the urine. The route of administration does not influence the way in which the amino acids are metabolized.

Comparison of different protein evaluation systems for growing pigs: Digestible crude protein, and total, faecal digestible and ileal digestible amino acid intakes as performance response predictors

open access: yesAgricultural and Food Science, 1994
The validity of apparent faecal digestible crude protein and total, apparent faecal or ileal digestible amino acid intakes (lysine, threonine and methionine) as animal performance predictors was evaluated on the basis of digestibility coefficients ...
