The effect of herbal supplements on the carcass characteristics, fatty acid profile and meat quality attributes of broilers ; 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 ...
