Efeito do tratamento da água por campo magnético sobre os parâmetros séricos e espessura de gordura subcutânea

The goal of this study was to evaluate the effect of magnetic water on blood cells counts, biochemical profile, blood gas level and subcutaneous fat thickness of Jersey cows. This research was carried out at Agencia Paulista de Tecnologia dos Agronegocios - APTA, SP. Twenty six Jersey cows from the APTA were allotted into two groups: control (n=13), drinking regular water and the group consuming magnetic water (n=13). The animals were lactating around 150 days and pregnant around 60 days. Blood samples were collected from caudal auricular artery and jugular vein. The water treatment had no effect on hemogram (p>0.05). Higher pH (7.448 vs 7.407 mmHg, p<0.05) and lower PaCO 2 (37.97 vs 42.47 mmHg, p<0.05) levels were detected in arterial blood of the group drinking magnetic water. The concentration of Na ion (138.8 vs 145.5 mmol/l, p<0.05) and serum triglycerides (10.4 vs 22.6 mg/dL, p<0.05) were significantly lower, resulting in smaller osmolality (273.30 vs 280.99 mOsm/kg, p<0.05) and subcutaneous fat thickness (0.2 vs 1.3 mm, p<0.05). In summary, the water treatment, evaluated in this study, may have decreased the risk of some metabolic disorders, such as acidosis and high serum concentration of Na and carbon dioxide.
