Effect of Different Mechanical Vibration on Blood Parameters of One Day Old Broiler Chicken
Mechanical vibrations are congenital to any system of transportation. In poultry industry, the higher or lower intensity of this agent during the transportation of eggs and chickens can increase the production losses and decrease the efficiency of the system as a whole. This study was carried out to investigate the effects of mechanical vibration (MV) generated by mechanized equipment on eggs, chickens mortality and levels of some blood biochemicals (triglyceride, glucose, cholesterol, calcium, phosphorus, urea) were analyzed in one days chickens. The data showed that the glucose and urea concentrations in blood of one day old chicks and their mortality increased with increasing vibration levels but calcium, cholesterol and triglyceride levels decreased. Levels of vibration seemed not to affect all of parameters. Mechanical vibrations may be responsible for the incidence of cracks, in addition to promoting the agitation of internal constituents (yolk and albumen), which could potentially compromise the quality of birth and hatchlings. The mechanical vibration are related to stress, discomfort and depreciation of the welfare of the birds, changed in glucose and corticosteroids levels and thus affect other factors as well as the quality of the meat.
