Modifying the Quality of Pig Carcasses, Meat, and Dry Fermented Sausage from Black Slavonian Pigs by Selecting the Final Body Weight and Nutrition.

A total of 96 Black Slavonian pigs were subjected to the research, in which they were split into 6 groups. Three groups (100, 120, and 130 kg) were fed a higher level (HL) of crude protein in fodder mixtures (CPFM), and three groups (100, 120, and 130 kg) were fed a lower level (LL) of CPFM. After the pigs were slaughtered, pig carcasses were dissected and the meat and halves quality indicators were determined. According to the influence of the final body weight (BW) and nutrition of pigs on the quality of their halves, meat, and dry fermented sausages (kulens), it was concluded that feeding an HL of CPFM increased the proportion of loin, belly rib part, and chin and increased the muscle tissue in the ham, loin, shoulder, neck, and belly rib parts. However, the chemical composition of the meat and the sensory properties of the kulen were not significantly affected by feeding the pigs an HL of CPFM. It was concluded that, by selecting the final BW and adjusting the feeding strategies for pigs, it is possible to modify the conformation and composition of pig carcasses and the quality of meat and kulens produced from the Black Slavonian pig, which is important because consumers prefer products with certain characteristics and of a standard quality and are ready to pay for them.

Slaughter Indicators, Carcass Measures, and Meat Quality of Lamb Fattened with Spelt (Triticum aestivum spp. Spelta L.).

The aim of this research was to investigate the slaughter indicators, carcass measures, and meat quality of lambs fattened with spelt. Lambs consumed various feed mixtures (1000 g day-1 lamb-1): I-control group; II-group with 10% dehulled spelt; III-group with 20% dehulled spelt. In the blood, the concentrations of minerals (calcium, phosphorus, magnesium, and iron), biochemical parameters (urea, glucose, total proteins, albumin, globulin, cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, ß-hydroxybutyrate, non-esterified fatty acids, glutathione peroxidase, and superoxide dismutase), and hepatic enzymes (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyltransferase, and creatine kinase) were determined. After slaughter, carcass development was measured. Samples of musculus semimembranosus were taken, of which the physical properties were analyzed. By analyzing the production properties of the lambs, we found that the slaughter characteristics of the lamb carcasses and the physical properties of the lamb meat as well as most biochemical indicators and enzymes did not significantly differ. The concentrations of albumin were increased in the groups with 10% and 20% spelt, as was the activity of alkaline phosphatase in the group with 20% spelt. The presented results indicate that spelt is an appropriate ingredient in the diet for weaned lambs.
