Ultrasonic Study of Methionine
نویسندگان
چکیده
The ultrasonic velocity (U), density (ρ) and viscosity (η) measurements have been carried out for L-Methionine in aqueous sodium chloride, potassium chloride and lithium chloride as a function of composition at 303K. Experimental data have been used to estimate the adiabatic compressibility (β), change (∆β) and relative change in adiabatic compressibility (∆β/β°), acoustic impedance (z), limiting apparent metal compressibility (φk°) limiting apparent molal volume (φ°v) and the constants (Sk, Sv) and viscosity B co-efficient. The results are discussed in terms of structure-making (or) structure -breaking effects of amino acids in the mixtures.

Bio-efficacy comparison of herbal-methionine and DL-methionine based on performance and blood parameters of broiler chickens
This study was conducted to compare the bio-efficacy of herbal methionine (H-Met) relative to DL-methionine (DL-Met) on 160 “Ross 308” broiler chickens. DL-Met and H-Met were added to the basal diet in eight experimental treatments with three and four concentrations respectively in starter, grower and finisher period. Blood parameters which were measured at 24 and 42 days of age consisted of: s...

This study was conducted to investigate the effect of dietary chromium-methionine (Cr-Met) supplementation on growth performance, feeding behavior and physiological responses of Holstein male calves during two different phases of body weight (BW). Twenty six (153.5±9.83 kg of BW) male calves were divided in two groups (n=13) and randomly assigned to treatments: 1) control and 2) Cr-Met (1.1 mg ...

Introduction: Feathers are important body structures that act as surface insulators to reduce maintenance energy requirements and also to protect skin against abrasions and infection. The purpose of this study is to investigate the effects of methionine injection into the yolk sac on development of feather follicle in chicken embryo. Methods: 50 fertilized eggs (weighting 50±0.4 gr) of Ross×...
