“…Thus, it is likely that SGV-mediated increase in growth performance as shown in this study would be the consequence of altered gut morphology (e.g., thinning the intestine), thus facilitating efficient nutrient absorption. Indeed, it is well-known that dietary additives with antibiotic activity have been reported to affect small intestinal morphology, thereby leading to better nutrient digestion and absorption (Jukes et al, 1956;Hill et al, 1957;Humphrey et al, 2002).…”

The present study was conducted to investigate whether dietary sanguinarine (Sangrovit ® , SGV) could affect growth performance, relative organ weigths, gut microbiota, serum cholesterol levels, and malondialdehyde contents of leg meat in broiler chickens. A total of 840 day-old male broiler chicks (Ross breed) was randomly placed on 28 floor pens with rice straw as a bedding and subjected to one of four experimental diets; corn-soybean meal based control diet, the control diet added with avilamycin at 10 ppm as growth promoter (AGP) and SGV at the level of 20 (SGV20) or 50 ppm (SGV50). The final body weight (BW), daily BW gain, and feed conversion ratio (FCR) were significantly improved (P＜0.05) in broiler chickens fed either AGP, SGV20 or SGV50 compared with the control diet-fed chickens. Compared with the control group, relative jejunal weight was significantly lowered (P＜0.05) in SGV20-fed chickens and relative jejunal or ileal length was significantly increased (P＜0.05) in all SGV-fed chickens. Dietary SGV20, but not AGP, altered gut microbiota (especially increase in cecal lactic acid bacteria) compared with the control diet-fed chickens. Total cholesterol of broiler chickens fed on a diet containing SGV20 or SGV50 vs. the control diet was significantly reduced. Finally, the content of malondialdehyde in thigh meats as an indicator of lipid peroxidation was significantly lowered (P＜0.05) by dietary SGV compared with that seen in the control chickens. In conclusion, our study clearly reveals that supplementation of SGV into the broilers' diet at 20 or 50 ppm improved growth performance and altered various biological and physiological parameters such as relative organ weights, serum cholesterol levels, gut microbiota, and meat qualities in broiler chickens.

“…The inclusion of antibiotic growth promoters in the feed of farm animals has been banned in the European Union since (EU, 2005, while their use is under consideration in other countries around the world due to the potential development of antibiotic resistant bacteria (Jukes et al, 1956;Greko, 2001;Spais et al, 2001;Roe & Pillai, 2003). Consequently there has been a growing interest in the identification and evaluation of alternative feed additives that would satisfy consumers' demands and would be closer to environmentally friendly farming practices.…”

The effect of sex and the supplementation of the prebiotic, mannan oligosaccharides (MOS), the acidifier, calcium propionate (CPr) or their combination in the feed of Japanese quail (Coturnix japonica) on their performance and carcass quality was examined in this experimentation. Three hundred, 1-day old Japanese quail were divided into four groups with three replicates each. One group that served as control received the basal diet. The three experimental diets consisted of the basal diet to which either 6 g CPr/kg, 2 g MOS/kg or both 2 g MOS/kg and 6 g CPr/kg was added. The body weight, feed consumption, feed conversion ratio (kg feed/kg weight gain) and mortality were examined at weekly intervals. At the end of the 42-day feeding period the birds were slaughtered, the carcasses were processed and the carcass weight, carcass dressing percentage and carcass part percentages were calculated. Also, the breast meat composition and its fatty acid profile were analyzed. Results showed that the female quail had a higher body and carcass weight and liver to live weight percentage, whereas they had lower carcass dressing percentage than males. The dietary addition of MOS increased body and carcass weight, whereas it decreased liver to live weight percentage and crude fat content of the breast meat. The dietary addition of CPr lowered carcass dressing percentage and ash content of the breast meat. Interactions between the two examined supplements were observed in feed consumption, feed conversion ratio and carcass weight. An interaction between MOS and sex was observed on carcass weight. It was concluded that MOS and calcium propionate can be used effectively in Japanese quail diets. ________________________________________________________________________________
