Problems solved by technology

[0002] Adding antibiotics to livestock and poultry feed can promote the disease prevention and growth of animals to a certain extent, but excessive use will lead to antibiotic resistance of pathogenic bacteria, which will affect the health of animals and humans. Antibiotics will be completely banned in feed

Embodiment 1

[0032] The application of a kind of rhamnolipid in broiler feed additive comprises rhamnolipid. The dosage of the rhamnolipid in the feed is 500 mg rhamnolipid / kg feed in terms of mass ratio.

[0033] Corn 55%, soybean meal 38%, phosphorus 1.4%, stone powder 1.0%, salt 0.3%, oil 3.0%.

[0034] The rhamnolipid is in the form of a dark brown viscous paste, and the rhamnolipid is mixed with silicon dioxide using a mixing device, so that the silicon dioxide is adsorbed to form a uniformly dispersed powdery solid, and the silicon dioxide is mixed with silicon dioxide. The ratio of rhamnolipid is 1.5:1.8.

Embodiment 2

[0036] A broiler feed additive comprising rhamnolipid. The dosage of the rhamnolipid in the feed is rhamnolipid 1000 mg / kg feed in terms of mass ratio.

[0037] Corn 55%, soybean meal 38%, phosphorus 1.4%, stone powder 1.0%, salt 0.3%, oil 3.0%.

[0038] The rhamnolipid is in the form of a dark brown viscous paste, and the rhamnolipid is mixed with silicon dioxide using a mixing device, so that the silicon dioxide is adsorbed to form a uniformly dispersed powdery solid, and the silicon dioxide is mixed with silicon dioxide. The ratio of rhamnolipid is 1.5:1.8.

[0039] 1. Effects of rhamnolipids on broiler performance and volatile fatty acids

[0040] Select 840 1-day-old yellow-feathered broiler chickens and randomly divide them into 4 groups. The negative control group (NCO) is fed with a basal diet without antibiotics, and the positive control group (ANT) is fed with a basal diet + antibiotics 200 mg / kg. Experimental group 1 (RLS1) were fed basal diet + rhamnolipid 500mg...

Abstract

The invention discloses an application of rhamnolipid in a broiler feed additive, wherein the rhamnolipid and a feed are in a mass ratio of 100 to 5000mg rhamnolipid / kg feed. The rhamnolipid additiveis added into the broiler feed, so that the intestinal absorption function of broilers is improved, and the weight and daily gain of broilers are increased. The content of volatile fatty acids in intestinal tracts is increased, which facilitates the balance of intestinal microorganisms. Intestinal inflammation in a stress state can be reduced. Intestinal functions are protected. The immunity of organisms is improved. The application of antibiotics in the feed is reduced. Rhamnolipid is safe and non-toxic in oral administration, and is a safe and green antibiotic substitute. The feed containingthe broiler feed additive has a remarkable repairing effect on intestinal inflammation damage when being fed.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to the application of a rhamnolipid in broiler feed additives. Background technique [0002] Adding antibiotics to livestock and poultry feed can promote the disease prevention and growth of animals to a certain extent, but excessive use will lead to antibiotic resistance of pathogenic bacteria, which will affect the health of animals and humans. Antibiotics will be completely banned from feed. After antibiotics are banned, how to protect animal health and improve the digestion and absorption rate of nutrients has become an important issue. Especially in the broiler breeding process, due to poor breeding environment, high-density intensive breeding mode and other reasons, it is easy to cause immune stress, which leads to the occurrence of broiler diseases and the decline of production performance. How to alleviate the immune stress under the condition of prohibiting antibiotics E...
