Fattening of Polish Holstein-FriesianSimple Summary: Cattle raised beneath various production systems differ in their capability to accumulate adipose tissue. Whereas the deposition of intramuscular fat is normally regarded as advantageous, excessive amounts of subcutaneous and internal fat are undesirable. This study compared the fatty acid (FA) profiles of 4 sorts of fat depots from crossbred bulls (Polish Holstein-Friesian Limousin, PHF LM) fattened semi-intensively (SI) and intensively (I). Intramuscular fat was most abundant in total polyunsaturated fatty acids (PUFAs), n-3 and n-6 PUFAs, and functional fatty acids C 18:two, C 18:three, C 20:four and C 20:five in comparison with all the remaining fat varieties. In addition, note that external fat was more abundant in conjugated linoleic acid (CLA) than other fat kinds. This locating may well have implications for each the beef sector and, on account of the observed differences in FA composition, human well being. Abstract: This study was developed to examine the fatty acid (FA) profiles of 4 sorts of fat depots from crossbred bulls (Polish Holstein-Friesian Limousin, PHF LM) fattened semi-intensively (SI) and intensively (I). Intramuscular fat was most abundant in total polyunsaturated fatty acids (PUFAs), n-3 and n-6 PUFAs, and functional fatty acids C 18:2, C 18:three, C 20:four and C 20:five in comparison with the remaining fat varieties. Additionally, note that external fat was far more abundant in conjugated linoleic acid (CLA) than other fat kinds. Grass silage fed to cattle through fattening had a advantageous influence on the FA profile of beef, and a rise within the volume of concentrate within the ration didn’t decrease beef good quality.

Introduction Recent years have witnessed increasing interest in the good quality of beef in lieu of aspects such as the growth price of cattle or carcass composition, which utilised to be the main concentrate of producer.
