Application of Origanum Oil in layer culture

Due to the potential harm to human beings caused by the drug residues of antibiotic feed additives such as chlortetracycline, oxytetracycline, olaquindox, asan in animal products, all countries have stipulated that such products are strictly forbidden to be used in laying hens In order to reduce the occurrence of E.coli, Salmonella and other bacterial diseases in laying hens, improve the disease resistance ability of laying hens, and give full play to the high-yield performance of laying hens Since 2007, Origanum Oil, a new type of natural plant extract, has been used in laying hens to replace antibiotic additives Through the promotion and application in recent two years, obvious economic and social benefits have been achieved One of the problems in the production of laying hens is that bacterial diseases are still the frequent diseases of laying hens, mainly including Escherichia coli and Salmonella Especially in the hot summer, yolk peritonitis is the main cause of high death rate Some layer breeders use drugs in a disorderly way, which makes the chickens resistant to the drugs Secondly, the immunity of chicken is low, the antibody of immune vaccine is low, and some viral diseases are induced For example, some laying hens are immunized with Newcastle disease and bursa of Fabricius according to the procedure, but some chickens are still ill in the safe period With the improvement of people's living standards, the quality of livestock products is required to be higher and higher In recent years, the harm of some high residual drugs and drug additives to human body has attracted great attention Many drugs, such as chlortetracycline, oxytetracycline and ethanol, have been forbidden to be used in laying hens The effect of Origanum Oil: Origanum is a perennial herb of Labiatae, which has a strong fragrance and is like hyssop, slightly bitter and spicy Origanum Oil is the volatile oil extracted from the plant Origanum It is mainly composed of thymoquinone, thymol, dipentene, isothymol, and galoroxylol Origanum Oil was widely used in food, beverage, candy, seasoning and meat products as antioxidant, antiseptic and fresh-keeping agent It is a food flavor permitted by the state In recent years, Origanum Oil has been used in animal health products industry According to the applied research, Origanum Oil has two major functions: first, it has a strong anti intestinal bacteria effect, and has a strong bactericidal effect on E Due to the normal metabolism function of the fine film, the physiological functions of some important thin films are lost Therefore, Origanum Oil has strong antibacterial, bactericidal and antibacterial functions The other is to promote growth and enhance the immune function of the body Origanum Oil can improve the activity of digestive enzymes, thus promoting the digestion and absorption of nutrients, improving feed conversion rate, promoting growth, increasing egg production, enhancing the function of the body and improving the specific immunity of the body In addition, Origanum Oil has the characteristics of rapid action, no residue and no drug resistance Application method and effect application method: add 10% Origanum Oil premix 100 g per ton of feed in the whole process of chicks, adult chickens and laying hens From June to September, each ton of feed for laying hens was added with 150g oregano oil premix The treatment dose after the onset of the disease was 200 grams per ton The results showed that the resistance of chickens, the incidence of digestive tract diseases, the ratio of feed to meat and the evenness of the whole chickens could be improved According to the experiment, the layer can save 0.3KG feed, the survival rate of brood period is 98%, 3 percentage points higher than that of no addition, the survival rate of brood period is 96%, 4 percentage points higher than that of no addition 350 kg of feed is saved in 350 days for 1000 laying hens, and 2 yuan per kg of full price feed is equivalent to 700 yuan of feed saved According to the application comparison, the application of oregano oil as a drug additive for every 10000 laying hens will generate an extra benefit of 7000 yuan in the whole year, and 1.75 million laying hens will be used in the whole year, with an annual economic benefit of 1.22 million yuan In addition, it can produce pollution-free green eggs and improve the market competitiveness of laying industry It can be seen that Origanum Oil is an ideal drug additive, which can not only control the occurrence of intestinal bacterial disease, improve the survival rate, but also reduce the ratio of feed to meat and feed to egg, and achieve good economic benefits.
