Effects of green tea phytosome on growth performance and intestinal integrity under coccidiosis infection challenge in broilers
ABSTRACT: This research examined the effects of feeding phytosomal green tea on broilers infected with coccidia. To provide phytosome, green tea extract was loaded into soy lecithin. Groups of chicks included uninfected and untreated control (NC), infected and untreated control (PC), infected and tr...

| description | ABSTRACT: This research examined the effects of feeding phytosomal green tea on broilers infected with coccidia. To provide phytosome, green tea extract was loaded into soy lecithin. Groups of chicks included uninfected and untreated control (NC), infected and untreated control (PC), infected and treated with salinomycin control (SC), infected and treated with 300 and 400 mL of green tea extract (GTE300, GTE400), infected and treated with 200, 300, 400 and 500 mL of green tea phytosome (GTP200, GTP300, GTP400, and GTP500). At 14-days posthatch, chickens were orally gavaged, except the NC group with a coccidia vaccine 30 times larger than the approved dose. Body weight (BW), feed intake (FI), and feed conversion ratio (FCR) were determined at 7, 14, 20, 28, 35, and 42 d. The characteristics of the carcass, internal organs and intestinal morphology were assessed on d 42. Applying overdose of coccidiosis vaccine showed experimental Eimeria infection, led to decrease in FI and BW, and increased FCR compared to PC group (P < 0.001). Meanwhile salinomycin, green tea extract, and green tea phytosome compensated the negative effects of Eimeria infection on growth performance. The treatments did not affect carcass, breast, and thigh relative weights. Interestingly, abdominal fat percent was significantly lower in chickens fed GTP300, GTP400, and GTP500 than in those fed GTE300, GTE300, and GTP200 (P < 0.0001). In comparison to the basal diet plus green tea extract forms and NC groups, the PC group increased the relative weights of the liver, spleen, bursa, and pancreas (P < 0.05). The highest values of villus height and villus height to crypt ratio were obtained in duodenum, jejunum and ileum in GTP300 group (P < 0.0001), while, villi diameter in duodenum and ileum decreased the most in GTP300 and GTP500, respectively (P < 0.0001). Consequently, as natural anticoccidial drug delivery systems, 300 mL of green tea phytosome can be introduced as the optimal dose to maximize the benefits of phytosome for intestinal integrity and reduce the consumption of green tea extract. |
