Embodiment 1
[0053] The preparation of embodiment 1 biological feed composition
[0054] The preparation method of the yeast metabolite is as follows: the yeast culture is crushed, extracted with water as a solvent to obtain an extract; the extract is concentrated and centrifuged to collect a supernatant; the supernatant is purified, concentrated and dried to obtain the product.
[0055] Organic trace elements are calculated as trace elements, including copper glycinate (5kg as copper), ferrous fumarate (30kg as iron), zinc lactate (20kg as zinc), manganese methionine (10kg as manganese), and yeast selenium (80g in terms of selenium), chromium nicotinate (90g in terms of chromium), and 85kg of yeast metabolites, and mix well to obtain.
Embodiment 2
[0056] The preparation of embodiment 2 biological feed composition
[0057] Superfinely pulverize the yeast culture (diameter less than 10 μm) to obtain the ultrafine powder of the yeast culture, extract it with water as a solvent, and obtain the extract; concentrate the extract, in L / kg, and obtain the concentrate after concentration The ratio between the volume of the yeast culture and the quality of the yeast culture is 5:1 (equivalent to 5L of concentrated liquid obtained from 1kg of yeast culture), centrifuged at 10,000 rpm at a high speed, and the supernatant after centrifugation is placed on a macroporous adsorption resin column Adsorb, collect the ethanol eluted part, obtain the ethanol eluate, concentrate and spray dry, and obtain the yeast metabolite.
[0058] Organic trace elements are calculated as trace elements, including copper glycinate (6kg as copper), ferrous fumarate (34kg as iron), zinc lactate (25kg as zinc), manganese methionine (12kg as manganese), and y...
Embodiment 3
[0059] The preparation of embodiment 3 biological feed composition
[0060] Superfinely pulverize the yeast culture (diameter less than 10 μm) to obtain the ultrafine powder of the yeast culture, extract it with water as a solvent, and obtain the extract; concentrate the extract, in L / kg, and obtain the concentrate after concentration The ratio between the volume of the yeast culture and the quality of the yeast culture is 5:1 (equivalent to 5L of concentrated liquid obtained from 1kg of yeast culture), centrifuged at 10,000 rpm at a high speed, and the supernatant after centrifugation is placed on a macroporous adsorption resin column Adsorb, collect the ethanol eluted part, obtain the ethanol eluate, concentrate and spray dry, and obtain the yeast metabolite.
[0061] Organic trace elements are calculated as trace elements, including copper glycinate (7.5kg as copper), ferrous fumarate (50kg as iron), zinc lactate (37.5kg as zinc), manganese methionine (15kg as manganese), ...
