Kvalitet mesa grudi brojlera hranjenih brašnom od kalifornijskih glista i svežim glistama (Lumbricus rubellus)

The goal of the work was to investigate the physical and chemical characteristics of the meat of broilers fed with mixtures in which fishmeal had been replaced with fresh earthworms and worm meal. The experiment was carried out on 100 day-old chickens of both sexes, Hybro provenance, divided into 4 groups, 25 broilers each. The experiment lasted for 42 days and had three phases: the first lasted for 3 weeks, the second 2 weeks and the third 1 week. The control group of broilers were fed with complete feed for chickens for fattening, of standard fiber and chemical composition, while I and II experimental groups were fed with mixture in which fishmeal had been replaced by worm meal in an amount of 50 and 100 %, and III experimental group obtained a mixture with no fishmeal, but fresh, chopped earthworms ad libitum instead, from the 1st day to the end of the experiment. At the end of the experiment, on the 42nd day, the broilers were transported to a slaughterhouse. After individual weighing they were slaughtered, and primary processing and cooling of the carcasses were performed. Then the carcasses were cut up to the main parts and the breast samples were taken for examining the physical and sensory properties of the meat. The results of the investigation have shown that there was no difference in physical properties (colour, pH) of the breast meat (p>0.05) among the experimental groups. The breast meat sample ranking has shown that the E-II group samples were rated as the most acceptable while the least acceptable were the meat samples of the control group as well as of the group fed with food in which fishmeal was completely replaced with fresh earthworms.Cilj rada je bio da se ispitaju fizičke i senzorne osobine mesa brojlera hranjenih smešama u kojima je izvršena supstitucija ribljeg brašna svežim glistama i brašnom od glista. Ogled je izveden na 100 jednodnevnih piladi oba pola Hybro provenijencije, podeljenih u 4 grupe po 25 brojlera. Ogled je trajao 42 dana i odvijao se u tri faze, pri čemu je prva faza trajala 3 nedelje, druga 2, a treća 1 nedelju. Kontrolna grupa brojlera je bila hranjena potpunim smešama za ishranu piladi u tovu, standardnog sirovinskog i hemijskog sastava, I i II eksperimentalna grupa hranjena je smešom u kojoj je riblje brašno supstituisano brašnom glista u količini od 50 i 100%, a III eksperimentalna gupa je dobijala smešu iz koje je potpuno isključeno riblje brašno s tim što je ova grupa dobijala od 1. dana do kraja ogleda sveže, seckane gliste ad libitum. Na kraju ogleda, 42. dana, brojleri su transportovaní u klanicu. Posle pojedinačnog merenja obavljeno je klanje, primarna obrada i hlađenje zaklanih brojlera. Potom se pristupilo rasecanju trupa na osnovne delove i uzimanju uzoraka grudi za ispitivanje fizičkih i senzornih osobina mesa. Rezultati ispitivanja su pokazali da između eksperimentalnih grupa nije bilo razlike u fizičkim osobinama (boja, pH) mesa grudi (p>0.05). Rangiranjem uzoraka mesa grudi kao najprihvatljiviji ocenjeni su uzorci E-II grupe, a kao najmanje prihvatljivi uzorci mesa kontrolne grupe i grupe hranjene hranom u kojoj je potpuno izvšena zamena ribljeg brašna svežim glistama
