Sažetak
The study aimed to determine the effect of dietary supplementation with leaves of industrial hemp (Cannabis sativa L.) on live weight, carcass (carcass weight, dressing percentage, individual cuts and giblets) and meat quality (pH, color, EZ-DripLoss, thawing loss, cooking loss, and shear force) traits of broiler chicken meat. The study was conducted on 100 male Ross 308 chickens, which were divided into 4 experimental groups. The control group (K-0) was fed without hemp leaves, while groups P-1, P-2 and P-3 were fed with the addition of 1%, 2%, and 3% industrial hemp leaves, respectively. The animals were slaughtered at 42 days of age. Group P-2 had the highest wing proportion (10.30%), which was significantly different from the group P-1 (9.43%; P = 0.004). Abdominal fat was significantly lower in groups P-2 (0.66%) and P-3 (0.59%) compared to group P-1 (1.06%; P = 0.004). The breast meat of group P-2 was the lightest (L* = 48.28) and differed significantly from that of group P-1 (L* = 46.24; P = 0.044). Group P-1 had the highest shear force value (17.22 N), which was significantly different from groups P-2 (P = 0.0047) and P-3 (P = 0.0506). Hemp leaves may improve the quality of broiler meat, but more research is needed to understand their full effect on other traits and health.
