Abstract
Of the total meat production in Serbia, pork makes up more than one half. This meat is often associated with cardiovascular diseases due to its high contents of fat and saturated fatty acids. The aim of this study was to determine the effect of various sources of fat in pig feeds on lipid indices of fat and muscle tissue of pigs from the point of view of consumer health needs. A total of 30 Yorkshire × Landrace crossbred pigs were divided into three experimental groups of 10 individuals and fed a complete finisher mixture for fattening pigs, with standard raw materials and chemical composition but with differing sources of fat. The results obtained show fat sources in pig feed significantly influenced the lipid indices, and the differences were more pronounced in fat than in muscle tissue of pigs.
Highlights
Pig production is an important part of agricultural production and of the agricultural service industries as suppliers of necessary equipment, raw materials, and preventive and protective materials [1]

No statistically significant differences were found between the average thrombogenic index (TI) of muscle tissue from the pig groups (TIs ranged from 1.08 to 1.10)
Summary
Pig production is an important part of agricultural production and of the agricultural service industries as suppliers of necessary equipment, raw materials, and preventive and protective materials [1]. The rapid development of pig breeding has led to an increase in the reproductive efficiency of sows and carcass quality, but the meat content of carcasses has almost reached a physiological maximum. In intensive sowing, during the production cycle, in one year from one sow, 36 fattening animals can be produced, of which about 1500 kg of meat can be obtained. It is more widely used than other meat species, while beef production has been suppressed, as its market price is lower. The total production of pigs is unevenly distributed worldwide and very differently across the continents, which is conditioned by a number of factors, such as climatic conditions, surface, structure and quality of arable land, development of agroindustrial complex and the like. The continent that stands out for pig production is Asia
