Embodiment 1

[0026] 1. Preparation of koji for strains

[0027] The Saccharomyces cerevisiae described in the present invention, preferably Saccharomyces cerevisiae ACCC20042, is purchased from the China Agricultural Microorganism Culture Collection Management Center, and the Saccharomyces cerevisiae ACCC20042 cell suspension is prepared as follows: Saccharomyces cerevisiae original bacteria test tube—— Small triangular flask seeds (maltose syrup 100ml, sugar content 7-8°Be) were incubated at 30°C for 10 hours—transfer to large triangle flasks (maltose syrup 600ml, sugar content 7-8°Be), and incubated at 30°C for 10 hours— Transfer to Karst jars (13kg of sugar water, 7-8 ° Be expanded cultivation) at 30°C for 10 hours—expansion of yeast seeds in Karst jars in distiller's jars (medium is 200kg of water per jar, 30kg of rice flour, Bran 10kg) The total culture time is 20h, which is the cell suspension of Saccharomyces cerevisiae.

Embodiment 2

[0030] Example 2: Preparation of cinnamon volatile oil (cinnamon oil)

[0031] Dry the cinnamon bark to a moisture content of 8wt%, crush it to 50 mesh, take 5000 g of the crushed cinnamon bark, soak it in 10 times distilled water for 1.5 hours, and extract the cinnamon according to the 2000 edition of the Pharmacopoeia of the People's Republic of China (Appendix XD) Oil (cinnamon essential oil).

Embodiment 3

[0032] Embodiment 3 inulin preparation

[0033] Wash the fresh Jerusalem artichoke tubers (purchased from the Horticultural Institute of Qinghai Academy of Agriculture and Forestry Sciences) with clean water, cut them into thin slices about 2 mm thick, and then dry them in a drying oven at 80 °C to a moisture content of 5 wt%, and grind them with a crushing mill for 40 Mesh sieve. Take 5Kg Jerusalem artichoke dry powder, add 100L water, extract at 70°C for 30min, and centrifuge at 3000r / min to get the supernatant. Inulin was obtained by spray drying the supernatant. Control the pressure of the spray dryer to 0.35MPa, and the air inlet and outlet temperatures are 190°C and 90°C respectively.

Abstract

The invention discloses a plant-source active feed additive and applications thereof in preparation of feed for livestock and poultry. The feed additive comprises germinated-soybean powder, tea dust culture, cinnamon volatile oil and inulin in a weight ratio of 1:0.5-1:0.01-0.05:0.01-0.03. The feed additive is used for preparation of feed for livestock and poultry. The feed additive is capable of improving palatability of the feed, promoting food taking, promoting growth of the livestock and poultry, boosting immunity and anti-stress capability of the livestock and poultry, decreasing the occurrence rate of livestock and poultry diseases, effectively relieving heat stress in summer, increasing the meat factor of commodities, improving the meat quality, and largely reducing discharge of face stench. The feed additive has a good market prospect.

Description

(1) Technical field [0001] The invention relates to a feed additive, in particular to a safe, high-efficiency, environment-friendly plant source active feed additive and its application. (2) Background technology [0002] The development of safe, efficient, and environment-friendly active functional feed has become a research hotspot for workers in animal husbandry departments. Active functional feed preparation refers to a type of feed preparation that can promote animal growth, enhance immunity, improve animal product quality, reduce environmental pollution, and improve ecological environment. [0003] There have been many researches on active functional feed preparations at home and abroad, including feed microbial preparations, prebiotics, acidifiers, enzyme preparations, Chinese herbal medicine additives, antioxidants, insect repellent drug additives, antifungal agents, flavoring agents, and binders. , emulsifier, livestock and poultry product quality improver, feed si...
