assessment of silage quality
Silage fermented mature after 40-60 days, enough lactic acid has been produced, and it can be fed. The silage quality can be easily assessed after opening, and the quality of silage is judged mainly based on color, aroma, taste and texture.
Superior green or yellowish green is lustrous and aromatic, giving a sense of comfort. Moist, soft, stem and leaf flowers can be clearly distinguished, not sticky.
Medium yellow brown or dark green, pungent acetic acid, aromatic. Soft, watery, stem and leaf flowers can be distinguished.
Low black or brown, pungent, spoiled, musty, rotten, sticky, agglomerated or too dry, can not tell the structure.
2. Prevent secondary fermentation
The opening area should be based on the daily feeding amount. If it is found to be mildewed, blackened or rancid after opening, it should be discarded. Take it from the top to the bottom of the raft from the top to the bottom, and then cover the sputum.
After the opening, it is necessary to prevent secondary fermentation of silage. The so-called secondary fermentation refers to the mildew phenomenon caused by the silage of the ventilated part of the silage after the silage is fed. Better quality silage is prone to secondary fermentation. After the second fermentation, the sugar content of the silage can be lost by 10%-24%. If there is a large amount of mold activity and mildew or nitrite production, it will cause a certain degree of harm after feeding the cattle and sheep.
The secondary fermentation begins after the silage is in contact with the air after opening, so the size of the opening should be determined according to the number of cattle and the amount of feed and the amount of feed, and the opening should be as small as possible. After each silage is removed, the surface is covered with a plastic film so that it is not ventilated. Silage that has undergone secondary fermentation. If it is not enough to be eaten, the upper layer of the already heated feed should be placed in a sealed plastic bag and fed as soon as possible. Spraying the surface of the lower silage with propionic acid at a dose of 0.5-1 liter per square meter, covered with a plastic film, can effectively inhibit the secondary fermentation process of the silage.
3. Reasonable feeding of silage
Silage contains a lot of organic acids and has a laxative effect, so it is not advisable to feed the cows later in pregnancy. Feeding alone is not good for cattle health and should be used in combination with carbohydrate-rich feeds and hay to increase nitrogen use by rumen microbes. Dairy cows have an adaptation process for silage, and the dosage should be gradually increased. The average daily feeding amount of adult cows is 15-25 kg, and the maximum daily feeding amount should not exceed 30 kg. The frozen silage is to be fed after being melted, and how much is taken each day. It cannot be taken in large quantities at one time. After the mold is deteriorated, the cows cannot be fed.
