20.500.12556/RUL-176021 Growth performance, carcass quality, and lipid metabolism in Krškopolje pigs and modern hybrid pigs comparison of genotypes and evaluation of dietary protein reduction This study compared the performance, meat quality and adipose tissue characteristics of Krškopolje pigs and modern hybrid pigs under identical rearing conditions, besides examining the effects of dietary protein reduction in both genotypes. A total of 29 pigs (14 Krškopolje and 15 hybrids) were assigned to litter into two dietary groups (high and low protein). The low-protein diet for hybrid pigs corresponded to the high-protein diet for Krškopolje pigs. All diets were iso-energetic. Dietary protein reduction decreased growth rate and muscle development in modern hybrids but had no significant impact on performance, quality or metabolic traits in Krškopolje pigs. Genotype differences revealed that Krškopolje pigs had lower growth rates, less lean and more fat deposition, as reflected in thicker subcutaneous and higher intramuscular fat compared to modern hybrids. Krškopolje pigs also exhibited higher myoglobin concentration and fatty acid saturation. Lipogenic enzyme activity and histo-morphological traits behaved in a tissue-specific manner but still indicated a greater lipogenic potential in Krškopolje pigs. This study provides valuable insights into breed-specific responses to dietary changes and highlights the unique characteristics of Krškopolje pigs. pigs local breeds Krškopolje pig breed comparison protein reduction performance carcass quality lipid metabolism meat quality true false true Angleški jezik Ni določen Članek v reviji 2025-11-18 13:51:39 2025-11-18 13:51:41 2025-12-17 03:58:32 0000-00-00 00:00:00 2024 0 0 19 str. iss. 22, art. 3331 Vol. 14 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 636.3 2076-2615 10.3390/ani14223331 216468483 animals-14-03331-v2.pdf animals-14-03331-v2.pdf 1 1CC837EA7C9C1AB7ED03762DAEFFEDF1 9ecea3b5f724ae556800d01d978fc822122f40987b6ec001f4dcb0a52d534a57 6f6bb5c7-c47d-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=222065 https://www.mdpi.com/2076-2615/14/22/3331 1 fc0e832d-c47c-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=222064 Veterinarska fakulteta 0 0 0
