Embodiment 1
[0019] The preparation method of the special feed for shelduck with cocky nose, the specific operation steps are as follows:
[0020] 1) Crush wheat, soybean meal and arrowroot and mix them, add brown sugar and lactic acid bacteria, mix evenly, seal and ferment, and filter after fermentation. The fermentation temperature is 25~30℃, and the fermentation time is 6~8d. Lactic acid bacteria destroy the cell walls of wheat, soybean meal and sagittarius, and decompose them into small molecular substances, which is beneficial to the digestion and absorption of shelducks;
[0021] 2) Mix the fermented fermentation residue with tea oil residue, Chinese herbal medicine preparation and compound enzyme preparation for enzymatic hydrolysis. The enzymolysis temperature is 45~52℃, and the enzymolysis time is 2~3h. The compound enzyme preparation destroys the cell wall of the substances in the fermentation residue, tea oil residue and Chinese herbal medicine preparation, dissolves the cytop...
Embodiment 2
[0029] The preparation method of the special feed for shelduck with cocky nose, the specific operation steps are as follows:
[0030] 1) Crush wheat, soybean meal and arrowroot and mix them, add brown sugar and lactic acid bacteria, mix evenly, seal and ferment, and filter after fermentation. The fermentation temperature is 28°C, and the fermentation time is 7 days. Lactic acid bacteria destroy the cell walls of wheat, soybean meal and sagittarius, and decompose them into small molecular substances, which is beneficial to the digestion and absorption of shelducks;
[0031] 2) Mix the fermented fermentation residue with tea oil residue, Chinese herbal medicine preparation and compound enzyme preparation for enzymatic hydrolysis. The enzymolysis temperature is 50°C, and the enzymolysis time is 2.4h. The compound enzyme preparation destroys the cell wall of the substances in the fermentation residue, tea oil residue and Chinese herbal medicine preparation, dissolves the cytopla...
Embodiment 3
[0039] The preparation method of the special feed for shelduck with cocky nose, the specific operation steps are as follows:
[0040] 1) Crush wheat, soybean meal and arrowroot and mix them, add brown sugar and lactic acid bacteria, mix evenly, seal and ferment, and filter after fermentation. The fermentation temperature was 27°C, and the fermentation time was 7 days. Lactic acid bacteria destroy the cell walls of wheat, soybean meal and sagittarius, and decompose them into small molecular substances, which is beneficial to the digestion and absorption of shelducks;
[0041] 2) Mix the fermented fermentation residue with tea oil residue, Chinese herbal medicine preparation and compound enzyme preparation for enzymatic hydrolysis. The enzymolysis temperature is 50°C, and the enzymolysis time is 2.7h. The compound enzyme preparation destroys the cell wall of the substances in the fermentation residue, tea oil residue and Chinese herbal medicine preparation, dissolves the cytop...
