Abstract: In this study the impact of pHp?wd=%28quantum therapy%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>quantum therapy on pHp?wd=%28meat quality%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>meat quality of slaughtered pigs was investigated. For this purpose the pigs were treated with different doses of magnet-infrared-laser (MIL) radiation. Animals were divided into four groups according to radiation doses (4096, 512, and 64 Hz, and control without application), which were applied in the lumbar area of musculus longissimus dorsi (loin) at various time intervals prior to the slaughter (14 d, 24 h, and 1 h). Animals were slaughtered and the pHp?wd=%28meat quality%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>meat quality was evaluated by determining of pH value (1, 3, and 24 h post slaughter), pHp?wd=%28drip loss%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>drip loss, pHp?wd=%28colour%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>colour, and pHp?wd=%28lactic acid%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>lactic acid and pHospHoric acid amounts. MIL therapy can be used in various fields of veterinary medicine as are surgery and orthopaedics, internal medicine, dentistry, pulmonology, gastroenterology, gynaecology, urology, nepHrology, and dermatology. The results achieved showed that MIL radiation used in a short period before slaughter (1 h) can cause a change in the pHp?wd=%28meat quality%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>meat quality, as reflected by the non-standard development of pH values, increases in pHp?wd=%28drip loss%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>drip loss, and changes of meat pHp?wd=%28colour%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>colour.
