Effect Of Exposing Calf's Muscle (Biceps Femoris) To A Hydraulic Pressure On Some of Intrinsic Histological And Physiological Traits

Abstrak

Samples of Biceps Femoris muscle of Iraqi calves has been exposed to a hydraulic pressure and measuring some of physiological and histological changes. The experiment divided to five treatments, TRT cont. with no hydraulic pressure applied (0 bar), TRT2 with 50 bar, TRT3 with 100 bar, TRT4 with 200 bar and TRT5 with 300 bar hydraulic pressure applied. The studied physiological properties were (water holding capacity WHC, shear force SF, fragmentation index FI, myofibril fragmentation index MFI, protein solubility and myoglobin concentrations Mg. some sample from each treatment were tested microscopically under magnification of 600, 1000 and 1600X to find out the changes in muscle microstructure. All treatments had an obvious effect on muscle samples and the differences between means were significant (p˂0.05). the histological profile of muscle differed significantly from each treatment to other with the increasing of applied pressure. At first (TRT2 50 bar) the muscle tissue structure had a slight deviation from TRT cont. while at the last treatment TRT5 (300 bar) the muscle microstructure torn up completely and the physiological tissue system had extremely disappeared.
