Example Embodiment

[0018] Example 1: Preparation of Rubber Comb Extract

[0019] Weigh 80kg of rubber bowl raw material and place it in an extraction tank, add first-grade water at 60°C according to a material-to-liquid ratio of 1:10, oil bath at 60°C-80°C, extract for 2 hours, repeat the extraction 3-4 times, and combine the extracts. Tannase was added at a ratio of 0.1 g / L, and the fermentation was carried out for 12 hours. The fermentation broth was frozen overnight for sedimentation, filtered, and the supernatant was concentrated under reduced pressure to a quarter of the original volume at 45°C. The concentrate was freeze-dried to obtain 17.7kg extract, the tannin content is 73.4% after testing.

Example Embodiment

[0020] Example 2: Broiler Breeding Experiment

[0021] 648 healthy 1-day-old AA male broilers with similar body weight were selected and randomly divided into 6 groups. Each group was set up with 6 replicates, with 12 chickens in each replicate. The rubber bowl extract feed additive (VT-1 group) was added to the basal diet, and the antibiotic (chlortetracycline) control group (addition amount of 300g / t) and the same commercial tannin control group (addition amount of 200g) were set at the same time. / t). The experiment was carried out in an online flat rearing mode, with free access to food and water. The initial temperature of the experiment was 35 °C, and then decreased by 2-3 °C every week until it dropped to 26 °C. Other management measures such as light, ventilation and immunization are implemented according to the feeding management manual. The diets were formulated and pelleted according to the nutritional requirements of NRC (1994) broilers. The composition and nutri...

[0028] Example 3: Broiler Breeding Experiment

[0029] 648 healthy 1-day-old AA male broilers with similar body weight were selected and randomly divided into 6 groups. Each group was set up with 6 replicates, with 12 chickens in each replicate. The rubber bowl extract feed additive (VT-2 group) was added to the basal diet, and the antibiotic (chlortetracycline) control group (addition amount of 300g / t) and the same commercial tannin control group (addition amount of 200g) were set at the same time. / t). Cultivation experiments were carried out as described in Example 2. The average daily weight gain (ADG) of each group at 1-21 days, 22-42 days, and 1-42 days was calculated. Statistically record the feeding amount of each group of chickens during the whole test period, calculate the average daily feed intake (ADFI) of each group according to the 1-21 day-old, 22-42-day-old, and 1-42-day-old stages, and calculate the average daily feed intake (ADFI) according to the daily wei...

Abstract

The invention provides a quercus variabilis/quercus acutissima cupule extract feed additive for broilers and an application method of the quercus variabilis/quercus acutissima cupule extract feed additive for broilers, and belongs to the field of feed production. The quercus variabilis/quercus acutissima cupule extract feed additive for broilers is prepared through the following process of with quercus variabilis/quercus acutissima cupules as raw materials, performing aqueous extraction so as to obtain a quercus variabilis/quercus acutissima cupule aqueous extraction solution, adding tannase,performing fermentation, performing freezing, enabling frozen substances to stay overnight and settle, performing filtration, performing concentration and drying on supernatant so as to obtain a quercus variabilis/quercus acutissima cupule extract, and mixing the quercus variabilis/quercus acutissima cupule extract with other feeds in a certain proportion so as to obtain the quercus variabilis/quercus acutissima cupule extract feed additive for broilers. The quercus variabilis/quercus acutissima cupule extract feed additive prepared by the method has quite prominent positive effects after being applied to broiler production. The feed additive is prepared from purely natural plant components, so that hurt of residual medicines in animal bodies to human bodies can be avoided, and people canbe safer and healthier when eating the broilers fed with the quercus variabilis/quercus acutissima cupule extract feed additive.

Description

technical field [0001] The invention relates to a feed additive of rubber bowl extract for broilers and an application thereof, belonging to the field of feed production. Background technique [0002] my country is a large animal husbandry country, and the use of feed additives is becoming more and more extensive. Growth promoters, food attractants, antioxidants, immune enhancers and other drugs are usually added to the feed to achieve the effects of promoting the growth of aquatic animals, preventing and curing diseases, enhancing the body's immunity, and saving nutritional needs. my country is a big country in the use of antibiotics, and it is also a big country in the production of antibiotics, with an annual production of about 210,000 tons. Among the raw materials of antibiotics, 97,000 tons are used in animal husbandry, accounting for 46.1% of the total annual output. It has become one of the countries with the most serious problem of antibiotic abuse in the world. T...
