Embodiment 1

[0010] Embodiment 1 prevents the feed preparation method of inducing broiler chicken sudden death

[0011] Add 0.002% of soybean isoflavones to compound feed and mix well to make pellet feed. After the temperature of pellet feed drops below 30°C, dissolve β-glucosidase (3000U / mg) in potable water Spray on the pressed pellet feed, and add β-glucosidase to account for 0.0005% of the total mass of the pellet feed.

Embodiment 2

[0012] Example 2 Determination of various indicators for preventing sudden death in broiler chickens

[0013] 1-day-old Arbor Acres (AA) male broiler chickens were selected and randomly divided into 9 treatments, each treatment had 10 repetitions, and each repetition group had 10 chickens, and the chicks were fed high-energy diet (metabolizable energy ME = 3.05Mcal / kg, crude protein CP = 22%), 22-42 days old fed high-energy diets for growing broilers (metabolizable energy ME = 3.25Mcal / kg, crude protein CP = 20%). The experiment adopts 3×3 factorial design. From the 1st day of age, soybean isoflavones are added to the compound feed at 0, 10, and 15 mg / kg respectively. After mixing, the pellets are pelleted. β-glucosidase is dissolved in drinking water and sprayed on the pressed pellet feed, and the added concentration is 0, 5, 10mg / kg feed respectively. The purity of soybean isoflavones is greater than 95%, and the β-glucosidase is 3000U / mg.

Abstract

The invention discloses a method for preparing feed for preventing the induction of the sudden death of chickens and application, and belongs to animal science and animal nutrition and feed science. In the method, soybean isoflavone and beta-glycuronide are added into high-energy feed for the chickens, and the beta-glycuronide decomposes beta-D glucosidic bonds, so that the soybean isoflavone in a form of glucoside can be converted into free aglycones with physiological activity, the soybean isoflavone absorption of gastrointestinal tracts is increased, the function of the cardiovascular regulation of the chickens by the soybean isoflavone is conducted, the occurrence of cardiac failure is reduced, and thus, the occurrence of the sudden death of the chickens is lowered.

Description

technical field [0001] The invention belongs to animal nutrition and feed science of animal husbandry, and in particular relates to a preparation method and application of a feed for preventing sudden death of broiler chickens. Background technique [0002] Broiler chicken sudden death syndrome is a common disease that occurs in broiler chickens, and the mortality caused by it accounts for about 1% to 5% of the total mortality, which seriously affects the economic benefits of broiler chicken breeding. Although the occurrence of this nutritional metabolic disease is related to genetic factors, the breeding and popularization of new varieties will take a long time, and the harm of metabolic diseases to broiler breeding cannot be solved in a short period of time. In addition, according to the pathogenesis of this disease, Some drugs can control the occurrence of these nutritional and metabolic diseases, but there are problems such as drug residues in animal products and the saf...
