Assessment of pig carcass meatiness in Serbia

The objective of this study was to determine lean meat content in pigs from different farms and smallholdings, which were slaughtered in one abbatoir in Serbia. In Serbia one third of the total number of pigs is slaughtered in slaughterhouses and two thirds in rural households. Results of this examination carried out on 12 523 slaughtered pigs from 9 farms and smallholdings showed that lean meat content in farm pigs ranged from 51.16± 4.31% to 53.27±2.94%. The average quantity of meat in farm pig carcasses was 52.29± 2.04%. The average lean meat percentage of pig carcasses from smallholdings was 48.99±4.85 %. All farm pig carcasses were classified on the basis of meatiness into class U (50.0-54.9% of lean meat content) while pig carcasses from smallholdings were graded as class R (the percentage of meat ranging from 45.0-49.9). Data about lean meat content of pig carcasses in Serbia have not been published during the past twenty years, because lean meat percentage has not been determined. Today, only three abattoirs in Serbia determine lean meat percentage and pay pig producers according to meatiness.
Cilj ovog rada bio je ispitivanje mesnatosti trupova svinja sa različitih farmi i iz otkupa koje su zaklane u jednoj klanici u Srbiji. U Srbiji se jedna trećina svinja zakolje u klanicama, a ostale dve trećine u domaćinstvima. Rezultati ispitivanja 12.523 zaklanih svinja sa devet farmi i iz otkupa pokazala su da je mesnatost svinja sa farmi bila od 51,16±4,31% do 53,27±2,94%, a u proseku 52,29±2,04%. Prosečna mesnatost trupova svinja iz otkupa bila je 48,99±4,85%. Svi trupovi svinja sa farmi prema mesnatosti svrstani su u klasu U (mesnatost od 50,0-54,9%), dok su trupovi svinja iz otkupa svrstani u klasu R (procenat mesa u trupu od 45,0 do 49,9%). Podaci o mesnatosti trupova svinja u Srbiji nisu objavljivani u poslednjih 20 godina, zato što se mesnatost nije određivala. Danas se samo u tri klanice u Srbiji određuje mesnatost svinjskih trupova, pri čemu se koriste električno-optički instrumenti.
