The objective of the research study was to determine the correlations between the lipid and glucose levels in blood serum of pigs and the parameters characterizing the quality of pork carcass and pork meat. The study performed covered 54 porkers (36 hogs barrows and 18 gilts/sows) derived from crossing the Naïma gilts and the P76-PenArLan hybrid boars. Immediately after slaughter, blood samples of the porkers were taken from their carotid arteries. In the blood serum, the levels of the following components were determined: glucose, triglyceride (TG), total cholesterol (CHOL), and HD cholesterol; also, the LDL cholesterol was calculated. After slaughter, the content of meat was determined in the carcasses using a CGM apparatus. In the longissimus dorsi (LD) muscle, the following was determined: pH values 45 min., 3 h, and 24 h after slaughter (at the height of the last rib), L*a*b* colour parameters, normal drip loss, and glycolytic potential. The coefficients of correlations were calculated among the traits analyzed. On the basis of the glucose content in the blood serum, the pigs in the population studied were divided into two groups, which differed in their lipid profiles, levels of glucose in the blood serum, and meat quality. The meat of pigs in the group characterized by higher levels of triglycerides (103.13 mg/100 ml vs. 76.32 mg/100 ml) and glucose (137.87 mg/100 ml vs. 81.98 mg/100 ml) had a lower pH 45 min. (6.34 vs. 6.54), 3 h(6.12 vs. 6.33), and 24 h (5.50 vs 5.58) post mortem, and a higher glycolytic potential (148.36 μmol/g vs. 134.90 μmol/g) as well as a higher normal drip loss (5.11 % vs. 3.9 5%). Significant correlations were confirmed to exist among the levels of lipids and glucose in blood serum and the characteristics of slaughter value and meat quality parameters (r = -0.28 ÷ 0.41 p ≤ 0.05).
