Meat quality of Istrian cattle

The goal of this work was to determine the beef meat quality of Istrian cattle using the chemical analyses' results for the quality of its meat. Five meat samples of Istrian cattle bull calves were sampled for the needs of chemical analyses at the end of fattening, at 23 months of age on average. The samples were sampled from m. longissimus dorsi (MLD) between the 7th and the 9th rib and laboratory researches included the basic chemical research, collagen and hidroxyproline quantity and fatty acid content of lipids in intramuscular fat in MLD. The obtained results have shown that the meat of Istrian cattle by its basic chemical composition did not differ from the content of meat of Simmental cattle, except in the fact that quantity of intramuscular fat was in average 0, 94 ± 0, 65 %, which is almost three times lower than in Simmental cattle. The content of connective tissue in the meat of Istrian cattle is relatively acceptable, where its quantity is in a positive correlation with meat tenderness. The results of fatty acid content of lipids in intramuscular fat in the meat of Istrian cattle have shown a significant quantity of saturated fatty acids (about 60%), which doesn't give this meat a complete nutritional advantage. But, from the point of view of sustainability and quality, because of that and a smaller quantity of polyunsaturated fatty acids (2, 41 ± 0, 60 %), such meat is less prone to auto oxidative changes in longer storage period or during processing of meat to the assortment of meat products in sausage type. Overall, the obtained results of our research indicate that the meat of Istrian cattle has a favorable quality for culinary preparation. Therefore, breeding and increasing self- sustainability of this breed has the future. Due to the fact that the population of Istrian cattle of almost 40.000 individuals 50 years ago reduced to only about 530 breeders suitable for breeding most experts emphasize the significance, value and need for that cattle breed to be preserved. Our researches' results agree with it.
