Supplementation of taurine and methionine to all-plant protein diets for rainbow trout (Oncorhynchus mykiss)
Taurine has been demonstrated to be a conditionally indispensable nutrient for several carnivorous fish species. Currently, trout feeds contain reduced levels of fishmeal which had been the primary source of dietary taurine. The reduction of fishmeal in the diet, and thus dietary taurine, may limit growth. A 12-week feeding trial was conducted using a factorial treatment design with taurine sup...
متن کاملEffect of Methionine Supplementation on Methionine Metabolism in Growing Cattle
Methionine is often the first limiting amino acid for growing cattle. This study was conducted to determine how methionine metabolism is regulated in the liver of growing steers. Six ruminally cannulated steers were used in a replicated 3 × 3 Latin square experiment. Either 0, 5, or 10 g/day L-methionine was infused into the abomasum. These treatments were designed to be deficient, adequate, an...
متن کاملoptimization of methionine level in broiler breeder diets, using of maximized economic profit and multi-criteria decision making methods
an experiment was conducted to determine the appropriate methionine level in broiler breeder’s diet. the treatments consisted of 6 levels of methionine (0.2, 0.25, 0.3, 0.35, 0.4 and 0.45% diets), with 4 replicates of 7 hens each for a duration of 8 weeks and for ages of 28 to 35 weeks. diets contained similar levels of protein metabolizable energy. the levels of the other amino acids were take...
متن کاملBreeder Age and Zinc Source in Broiler Breeder Hen Diets on Progeny Characteristics at Hatching
Metabolic, immune, and physical status of chicks can impact the incidence of morbidity and mortality of broilers during the first week of production. Assessments of chick quality are made primarily by subjective observations with few quantitative measurements. Given a better understanding of how broiler breeder hen age and nutrient intake may influence progeny physiology, certain actions can be...
متن کاملDL-methionine supplementation of rice-and-bean diets affects gamma-glutamyltranspeptidase activity and glutathione content in livers of growing rats.
Gamma-glutamyltranspeptidase (GGT-EC 2.3.2.2) activity and glutathione (GSH) content were measured in livers of female weanling Wistar rats (N = 5-18), submitted to rice-and-bean diets (13 and 6% w/w protein), both supplemented or not with DL-methionine (0.5 and 0.23 g/100 g dry diet, respectively). After 28 days, the rats on the rice-and-bean diets showed significantly higher levels (four time...
