Problems solved by technology

[0002] In the process of modern livestock and poultry farming, in order to prevent and treat animal diseases, excessive antibiotic products are often used to ensure the health of animals, but the excessive use of antibiotics often leads to the decline in the quality of animal meat products and their products and the enhancement of antibiotic resistance, resulting in transmission through the food chain. Human health is also severely affected by the antibiotic problem

Embodiment 1

[0037] Example 1: Acquisition of marine Rhodotorula yeast WYN1 and domestication of copper tolerance

[0038] (1) Fresh sea shrimp, starfish, seaweed and other biological samples collected from the Yellow Sea are placed in sterile YEPD medium, and red or pink round colonies are picked for further purification and culture. According to the accumulation of carotenoids in each strain, the strains with high carotenoid production were screened. Among them, the marine rhodotorula WYN1 with higher carotenoid production has oval cells without pseudohyphae; it forms red colonies on the YEPD medium prepared in seawater, with smooth surface and neat edges; it does not produce eggs on the sporulation medium Cystic spores, multilateral budding, no sporulation; no fermentation of sugar, no formation of starch-like compounds, and no inositol synthesis. Based on the above characteristics, it was preliminarily determined to belong to the genus Rhodotorula. Keep ramps in the refrigerator.

Abstract

The invention relates to a compound feed additive rich in carotenes and a preparation method thereof, belonging to the field of enzymic preparations of feeds. The compound feed additive rich in carotenes comprises the following components in parts by weight: 10-15 parts of antibacterial peptides, 10-20 parts of propolis, 10-15 parts of eucommia bark leaf extract, 15-30 parts of rhodotorula culture, 25-50 parts of morchella enzymatic powder, 5-10 parts of alfalfa powder and 0.01-0.02 part of tea polyphenol, wherein rhodotorula is rhodotorula sp. WYN1, with collection number of CCTCC No:M2014592. The compound feed additive has the beneficial effects that as used rhodotorula can produce high-yield carotenes and convert inorganic copper in a culture medium to chelated copper and enrich the chelated copper, the growth and development of animals are better promoted, the feed utilization rate is increased and the heat stability of the feed additive is improved.

Description

Technical field: [0001] The invention belongs to the field of feed, in particular to a feed additive. Background technique: [0002] In the process of modern livestock and poultry farming, in order to prevent and treat animal diseases, excessive antibiotic products are often used to ensure the health of animals, but the excessive use of antibiotics often leads to the decline in the quality of animal meat products and their products and the enhancement of antibiotic resistance, resulting in transmission through the food chain. Human health is also severely affected by the problem of antibiotics. [0003] Some natural substances derived from nature not only have good nutritional properties, but also have anti-virus, anti-inflammatory, anti-oxidation, and regulation of immune functions, etc., and have broad application prospects. [0004] The main components of propolis are flavonoids, phenols, lactones, coumarin, aldehydes and ketones, a small amount of iron, calcium, silicon...
