Učinkovitost biljnih dodataka prehrani na svojstva trupa, masnokiselinski sastav i kvalitetu mesa tovnih pilića

The present investigation was carried out to determine the effect of two herbal formulations, AV/LMP/10 (T1) (garlic, Allium sativum) and AV/HLP/16 (T2) (mixture of gugal, Commiphora mukul and fenugreek, Trigonella foenum-graecum with 50:50%), on the carcass characteristics, proximate composition, lipid profile including fatty acids, and meat quality attributes in Vencobb 400 broiler chickens. Broilers fed with the AV/HLP/16 (T2) formulation had significantly (P<0.05) superior carcass characteristics in terms of pre-slaughter weight, head, neck, shank, skin, stomach, intestine, giblet, and wholesale cut yield than the control and broilers supplemented with AV/LMP/10 (T1). Meat obtained from the broilers fed with the T2 formulation had a significantly (P<0.01) higher dressing percentage and lean percentage than the control broilers and the T1 supplemented broilers. Meat obtained from the broilers fed with the T2 formulation had significantly (P<0.01) higher moisture and protein content, and lower fat content than the control birds. Meat obtained from the broilers fed with the T2 formulations had significantly (P<0.01) lower triglycerides and higher phospholipids and cholesterol content than meat obtained from the control birds. A significant (P<0.01) increase was observed in the myristic, palmitic, oleic, palmitoleic, linoleic and behenic acid percentages, and a decrease in the stearic acid percentage in meat obtained from the broilers fed with the T2 formulation. Addition of the T2 formulation significantly (P<0.01) improved the physico-chemical quality and sensory scores of the chicken meat. The results of this study revealed that addition of herbal formulations had a significant effect on the carcass characteristics, proximate composition, fatty acid profile and meat quality attributes in comparison with the control birds.Ovo je istraživanje provedeno kako bi se ustanovio učinak dviju biljnih formulacija, AV/LMP/10 (skupina T1) (češnjak, Allium sativum) i AV/HLP/16 (skupina T2) (mješavina dobivena od stabla smirne mukul (Commiphora mukul) i piskavice (Trigonella foenum-graecum) u omjeru 50 : 50 %) na svojstva trupa, kemijski sastav - uključujući lipidni status i masnokiselinski sastav te kvalitetu mesa Vencobb 400 tovnih pilića. U odnosu na piliće kontrolne skupine i onih hranjenih formulacijom AV/LMP/10 (T1), pilići hranjeni formulacijom AV/HLP/16 (T2) imali su znakovito (P<0,05) kvalitetnija svojstva trupa s obzirom na tjelesnu masu prije usmrćivanja te dijelove trupa kao što su glava, vrat, bataci, koža, organi trbušne šupljine, crijeva, iznutrice i veleprodajni komadi pilića. Tovni pilići u skupini T2 imali su znakovito veći (P<0,01) postotak mesa od kontrolne skupine i skupine T1. Meso pilića iz skupine T2 imalo je znakovito veći (P<0,01) sadržaj vode i proteina te manji sadržaj masti od pilića u kontrolnoj skupini. Meso tovnih pilića u skupini T2 imalo je znakovito manje vrijednosti (P<0,01) triglicerida i veće vrijednosti fosfolipida i kolesterola nego meso pilića u kontrolnoj skupini. Znakovit je bio porast (P<0,01) postotka miristinske, palmitinske, oleinske, palmitoleinske, linoleinske i behenske kiseline te smanjenje vrijednosti stearinske kiseline u mesu tovnih pilića iz skupine T2. Dodatak biljne formulacije u skupini T2 znakovito je poboljšao (P<0,01) fizikalno-kemijska i senzorička svojstva mesa tovnih pilića. Rezultati ovog istraživanja pokazali su da dodatak biljnih formulacija prehrani tovnih pilića znakovito utječe na svojstva trupa, kemijski - uključujući lipidni i masnokiselinski sastav te kvalitetu mesa pilića u odnosu na kontrolnu skupinu
