Creatine monohydrate (CMH) has become a popular dietary supplement used by athletes to increase muscle performance. Creatine acts in muscles in the form of creatine phosphate, which provides muscle with ATP. The increased concentration of intramuscular kreatinfosfat draws water into muscle cells, thus increasing cell volume. It has been reported a significant increase in total body mass and lean body mass in CMH intake in humans, suggesting that pigs with the addition of CMH could showe a linear increase in growth during the period of complementary feeding. Creatine is not present in the feed of plant origin that requires the use of feed of animal origin as its source in diets for animals or the use of synthetic products. Among the feed of animal origin that is commonly used in formulating meal for pigs, the greatest amount of creatine is found in meat and bone meal (207.7 mg / kg), fish meal (1110.5 mg / kg) and poultry by product meal (201 mg / kg), with variations depending on the quality of raw materials and production process for obtaining. Currently there are three different synthetic forms of creatine at the market: monohydrate, phosphate and citrate. The amount and length of adding CMH may be the reason for the variation in the quality of meat in the differen groups of pigs. It was found that water loss, and firmness of Musculus longissimus are improved due to CMHC addition into the meal for fattening pigs in the amount of 3 g daily for 30 days, or 25 grams daily for five days before slaughter. Adding creatine in small amounts over a longer period of time can be just effective as addition of large quantities of creatine in a shorter period of time.
