Embodiment 1
[0042] Embodiment 1, the mensuration of alfalfa neutral detergent fiber content
[0043] (1) After cutting the alfalfa to 1-2 cm, place it in a dry and ventilated environment to dry naturally. The air-dried samples were ground with a food grinder to a particle size of 18 mesh.
[0044] (2) Put 1.03 g of the above-mentioned alfalfa sample and 100 ml of neutral washing liquid into a storage bottle (volume 150 ml); screw on the storage bottle cap, and tighten it properly to maintain internal and external ventilation. Then, put the bottle into the pressure cooker, add water to the neck of the pot (the place where the mouth of the bottle is convex), and put it on the fire. After boiling, adjust to a weak boiling state and keep for 10 minutes to degas. Do not cover the pressure cooker during this process.
[0045] (3) Tighten the cap of the preservation bottle, add water to the neck of the bottle, cover the lid of the pressure cooker and put it on the fire, keep the pressurized s...

[0050] Embodiment 2, the mensuration of Leymus chinensis neutral detergent fiber content
[0051] (1) After cutting the Leymus chinensis to 1-2 cm, place it in a dry and ventilated environment to dry naturally. The air-dried samples were ground with a food grinder to a particle size of 40 mesh.
[0052] (2) Put 0.97g sample of Leymus chinensis above and 100ml of neutral detergent into a preservation bottle (volume 150ml); screw on the cap of the preservation bottle, and tighten it moderately to maintain internal and external ventilation. Then, put the bottle into the pressure cooker, add water to the neck of the pot (the place where the mouth of the bottle is convex), and put it on the fire. After boiling, adjust to a weak boiling state and keep for 10 minutes to degas. Do not cover the pressure cooker during this process.
[0053] (3) Tighten the cap of the preservation bottle, add water to the neck of the bottle, cover the lid of the pressure cooker and put it on the fire, ...

[0058] Embodiment 3, the mensuration of white clover neutral detergent fiber content
[0059] (1) After cutting the white clover to 1-2 cm, place it in a dry and ventilated environment to dry naturally. The air-dried samples were ground with a food grinder to a particle size of 30 mesh.
[0060] (2) Put 1.08 g of the above-mentioned white clover sample and 100 ml of neutral washing liquid into a storage bottle (volume 150 ml); screw on the storage bottle cap, and tighten it properly to maintain internal and external ventilation. Then, put the bottle into the pressure cooker, add water to the neck of the pot (the place where the mouth of the bottle is convex), and put it on the fire. After boiling, adjust to a weak boiling state and keep for 10 minutes to degas. Do not cover the pressure cooker during this process.
[0061] (3) Tighten the cap of the preservation bottle, add water to the neck of the bottle, cover the lid of the pressure cooker and put it on the fire, keep th...
