Introduction and Objective: Medicinal plants can have potential supportive effects by enhancing the body's antioxidant system. These plant compounds are able to directly reduce the production of oxygen free radicals during all types of stress by inhibiting the producing enzymes. Generally, probiotics as food products are able to be freed from enzymatic digestion by mice and settle in a large amount at the end of the digestive tract of the host, especially in cecums. Studies have shown that probiotics strengthen intestinal flora and the immune system, as well as increase nutrient digestibility and improve growth performance. This research was conducted with the aim of studying The effect of different levels of Alpinia Officinarum powder on growth performance, lipid profiles, liver and antioxidant enzymes in Japanese quail under heat stress conditions
Materials and Methods: The experiment was conducted using 408 quail pieces of one-day-old chicks in the form of a completely randomized design with 17 experimental units with 6 treatments and 4 replications. Experimental treatments include: 1- Control (without Alpinia Officinarum powder and probiotics, feeding with basic diet); 2- Basic ration with 50 mg of Alpinia Officinarum powder; 3- Basic ration with 100 mg of Alpinia Officinarum powder; 4- Basic ration with 50 mg of Alpinia Officinarum powder + 2/0 g/kg Lactofid probiotic; 5- Basic ration with 100 mg of Alpinia Officinarum powder + 2/0 g/kg Lactofid probiotic; 6- The basic diet was lactofeed with 2/0 grams/kg of probiotics. Performance traits (weight gain, feed consumption and food conversion ratio) of quail chicks at 20, 10 and 35 days old and the whole period were investigated. At the end of the test period, one piece of bird was randomly weighed from each pen, killed and immediately skinned, and the carcass and its parts were weighed. At the end of the test period, one quail piece was randomly selected from each unit, and the orientation of blood parameters was taken.
Results and Discussion: Addition of sea buckthorn powder Alpinia Officinarum and probiotics caused a significant increase in body weight during rearing periods (P<0.05). Body weight was affected by sea Alpinia Officinarum powder and probiotics throughout the entire rearing period (1 to 35 days of age) (P<0.05). The parameters of feed consumption in the entire rearing period were significantly affected by experimental treatments (P<0.05). So that the simultaneous use of 50 and 100 mg of Alpinia Officinarum powder with 0.2 g/kg probiotic significantly reduced feed consumption compared to the control treatment respectively, the lowest and the highest food conversion coefficient during the rearing periods and the entire rearing period were observed in treatments 4 and 5 and the control treatment. Alpinia Officinarum powder has antioxidant properties, stimulates the secretion of digestive juices and is a strong g/kg, and the menthol present in this essential oil increases the digestion and absorption of nutrients by reducing the harmful microbes of the digestive tract and increasing the secretions of the pancreas and other digestive organs and, as a result, the weight of quails. By increasing the activity of digestive enzymes and neutralizing internal toxins produced by other microorganisms, probiotics cause better functioning of the intestinal absorption level and beneficial effects on poultry performance. Feeding cabbage Alpinia Officinarum powder and Lactofid probiotic had a significant effect on lipid profiles (P<0.05). Antioxidant substances in Alpinia Officinarum are mainly compounds with phenolic hydroxyl group, double bonds including flavonoids, unsaturated fatty acids and tannins. Polyphenolic compounds in galangal regulated the redox homeostasis balance in chickens and reduced membrane lipid peroxidation, which led to a reduction in the risk of free radical-related disorders and a decrease in serum triglyceride concentration. Saponin in galangal limits fat absorption in the small intestine by binding to triglycerides in the intestinal tract, which inhibits lipase activity. The highest concentration of aspartate aminotransferase was observed in the control group, and the lowest concentration was observed in treatment 4. The concentration of alanine transferase was significantly lower than the control group in the treatment containing kollanjan powder and probiotics (P<0.05). The concentration of superoxide dismutase enzyme increased in the treatment groups containing Alpinia Officinarum powder and lactofid probiotic compared to the control treatment (P<0.05). Horsetail Alpinia Officinarum powder and probiotic and their simultaneous use in the basic diet had no significant effect on glutathione peroxidase enzyme concentration (P<0.05). In a study, they noted that feeding broiler chickens an experimental diet containing Alpinia Officinarum powder (250, 500, and 750 mg) for six weeks resulted in increased levels of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, and catalase, which was consistent with the present study.
Conclusion: Based on the results of the present study, the use of Alpinia Officinarum powder and probiotics at the level of 0.2 g/kg improved body weight, feed consumption and food conversion ratio; It also improved lipid profiles, liver and antioxidant enzymes in birds.
