  • Changes in magnetic resonance relaxation times in the muscle tissue of broiler chickens = Spremembe v magnetno resonančnem relaksacijskem času mišičja brojlerjev
    Petrási, Z. ...
    In the course of this experiment two samples per occasion and per sex were taken from the breast muscle of the broiler chickens studied on eight examination dates (at hatching and at the age of 1, 2, ... 3, 4, 5, 6 and 7 weeks), which were then subjected to NMR proton spectroscopz examination. The procedure involved the recording of T1 and T2 relaxation times (directly at the time of sampling, and then 1, 3, 6, and 9 hours subsequent to this), and for the purpose of the quantitative examination of the water fractions multiexponential analysis of the T2 curves was also performed. The results obtained, which maz be regarded to be of a preliminary nature, indicate that three stages can be distinguished in the changes occurring in the water fractions of the breast muscle tissue. In the first week of life relaxation times decreased in parallel with decrease in tissue water content. Between the second and the fifth week no change in the T1 times was observed, the T2 times increased continuously, and the ratio of slow components decreased from 54 % at one day of age to 35 %. Finally, in the last week of the examination period, both the T1 and the T2 relaxation times decreased, while the ratio of slow components once more approached 50 %.
