How to identify the quality of hay
Identification of hay quality can be done from the following aspects. During the process of color modulation, there was no rain and sun exposure. The hay that had not been subjected to high temperature fermentation after being piled up was bright green. Anything that met the rain during the process of modulation and the moldy heat generated after stacking turned yellow-brown or dark brown. Moisture content The level of moisture in hay is the key to determining whether hay can be stored for long periods of time. The moisture content of hay should not exceed 17%. An easy way to check the moisture content of hay is to hold a bundle of hay by hand and twist it gently. If grass stems crack, it is slightly elastic and continuous, indicating that the moisture content is moderate (17%); if slight Torsion is fracture, indicating that it is too dry; if it can be twisted into a rope without cracking, it indicates excessive moisture. The odor of well-preserved hay has an aromatic smell. The musty hay is of poor quality. The content of protein, minerals, and vitamins contained in leaves of hay is much higher than that in stems. Leaves are rich in nutrients, good palatability, and easy to digest. Therefore, the number of blades directly affects the quality of hay. Therefore, in the process of modulation, the losses of the blades should be minimized. Castration stage has a great influence on the quality of hay. The timely hay coloration is green, aromatic, with many leaves and good quality. If castration is too late, it will cause a decline in quality. Impurity content If dry grass contains impurities such as dead branches, thorns, and sediment, it will affect the quality of hay, and the amount of impurities in hay should be minimized.
