Problems solved by technology

[0004] So far, the additives used in natural pasture silage are the silage additives used in cultivated forage and forage crops, but because the natural pasture is a mixed forage, its characteristics are quite different from those of a single type of cultivated forage and forage crops. It is particularly important to develop special additives suitable for pasture silage in natural grasslands

Embodiment 1

[0032] Present embodiment provides a kind of method for preparing natural pasture grass silage, and this method comprises the following steps:

[0033] 1) The pasture grasses in the Bashang meadow of Hebei Province were mowed in late July, and the cut length was 5-8 cm. Dissolve 0.025% inulin in a small amount of water and spray evenly on the pasture layer by layer, according to the water content of 65%-70% and the silage density of 450-500kg / m 3 Packed in 10L gland barrel, compacted and sealed layer by layer.

Embodiment 2

[0035] Present embodiment provides a kind of method for preparing natural pasture grass silage, and this method comprises the following steps:

[0036] 1) The pasture grasses in the Bashang meadow of Hebei Province were mowed in late July, and the cut length was 5-8 cm. Dissolve 0.05% inulin in a small amount of water and spray evenly on the pasture layer by layer, according to the water content of 65%-70% and the silage density of 450-500kg / m 3 Packed in 10L gland barrel, compacted and sealed layer by layer.

Embodiment 3

[0038] Present embodiment provides a kind of method for preparing natural pasture grass silage, and this method comprises the following steps:

[0039] 1) The pasture grasses in the Bashang meadow of Hebei Province were mowed in late July, and the cut length was 5-8 cm. Dissolve 0.10% inulin in a small amount of water and spray evenly on the pasture layer by layer, according to the water content of 65%-70% and the silage density of 450-500kg / m 3 Packed in 10L gland barrel, compacted and sealed layer by layer.

Abstract

The invention relates to the technical field of pasture processing, and particularly discloses a natural grassland forage grass silage and a preparation method thereof. A silage additive adopted during a preparation comprises 0.025%-0.20% wt of synanthrin, the silage raw material is natural grassland forage grass, and the natural grassland forage grass is mixed forage grass obtained by directly cutting on a natural grassland. The provided preparation method of the natural forage grass silage improves forage silage quality, specifically, improves content of lactic acid, crude fat and soluble carbohydrate in the silage, reduces content of propionic acid and NDF, and greatly reduces content of butyric acid.

Description

technical field [0001] The invention relates to the technical field of forage processing, in particular to a natural pasture silage and a preparation method thereof. Background technique [0002] At present, the production of pasture in natural grassland is mainly to make green hay, but in the process of hay preparation, there are losses such as rain, defoliation, oxidation and photochemistry. As an efficient way of forage processing and storage, silage has its unique advantages. Natural pasture silage can effectively preserve the nutrients in the pasture; improve the palatability and digestibility of the pasture; eliminate the germs and insect eggs attached to the pasture, and reduce the harm of diseases and insect pests to livestock; the natural pasture is a mixed grass group, and silage can Improve the palatability of pasture that livestock do not like to eat, and expand the source of feed; the silage production process is less affected by external conditions such as wea...
