Embodiment 1

[0029] (1) Weighing tauroursodeoxycholic acid;

[0030] (2) Mix tauroursodeoxycholic acid with feed premix raw materials to obtain a premix; or mix with a carrier to make a premix; said tauroursodeoxycholic acid is mixed with feed premix raw materials Conventional small-scale mixing equipment can be used. The selection and dosage of the feed premix raw materials and carriers refer to the conventional ones, and vitamin or mineral premixes are optional; the carrier is bran, corn flour or stone powder, etc.;

[0031] (3) Mixing the premix or premix obtained in the step (2) with the complete feed raw materials to prepare the complete feed. Conventional large-scale mixing and crushing equipment can be used for premix or premix and complete feed raw materials. The complete feed raw materials refer to conventional ones, and crushed corn, soybean meal, fish meal or other miscellaneous meal rations can be selected.

[0032] In this example, the formulations of each component are as fo...

Embodiment 2

[0034] Example 2 Effects of tauroursodeoxycholic acid on growth performance of broiler chickens under heat stress conditions

[0035] In this experiment, 640 44-day-old yellow-feather broilers were pre-fed for 3 days in the same environment, and then divided into two groups (the initial average body weight difference between the two groups was not significant). One group was raised in a high-temperature and high-humidity environment (the temperature was set at 32±1°C in the morning of the first day, and raised to 33±1°C in the afternoon of the same day, and so on, increasing by 2°C every day until the temperature reached the final temperature. The stress temperature is 36±1°C. The humidity remains unchanged at 75%±5%). The other group was reared in a constant temperature environment (24h: temperature 24±1°C, humidity 75%±5%).

[0036] With formula 1 of embodiment 1, do not add tauroursodeoxycholic acid as the basal diet of contrast, carry out experiment, experimental cond...

Abstract

The invention discloses an application of tauroursodeoxycholic acid in preparation of chicken feed additive, and a chicken feed, and particularly relates to the feed additive which is prepared from the tauroursodeoxycholic acid and can alleviate chicken heat stress. The tauroursodeoxycholic acid is found to have the function of alleviating the stress of a chicken in the environment with high temperature and high humidity, thus being capable of improving the organism redox state of the chicken and improving the conversion efficiency of the chicken feed; the tauroursodeoxycholic acid is a safe feed and does not contain the substances which are poisonous and harmful to the growth and the health of chicken flocks. The feed additive is less in adding amount of the tauroursodeoxycholic acid, and premix can be directly added into the feed additive, so that the adding process is convenient and fast; the feed additive is simple in preparation method and does not have special equipment requirement, thus having good popularization and application prospect.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to the application of tauroursodeoxycholic acid in the preparation of chicken feed additives and chicken feed containing tauroursodeoxycholic acid. Background technique [0002] Feed additives are substances with different uses that are artificially added to various compound or mixed feeds for some special needs. and the quality of meat products. With the development of animal nutrition, physiology, feeding, biochemistry, bioengineering, pharmacology, microbiology and other disciplines, the current feed additives have integrated various disciplines and various technologies, and their functions, types and applications have been obtained. On the other hand, most of my country belongs to the subtropical region, and presents a typical high-temperature and high-humidity climate every summer. The high-temperature and high-humidity climate has a great impact on modern i...
