Problems solved by technology

[0003] At present, there are still some problems in the method of using fermentation beds in dairy cow breeding in my country: There are a large number of bacteria and insect eggs in unfermented cow dung, sawdust, other biological residues and other litter materials
The disadvantage of this litter is that the fiber structure of the litter is broken with fermentation, the water permeability and air permeability are poor, and it hardens and agglomerates as the cows sit and rest
Not only can it not play the role of litter, but it is harmful to cow udders and hooves

Embodiment 1

[0020] Use extruded and dehydrated cow dung (about 70% moisture) and sawdust (50% moisture), mix according to the ratio of cow dung: sawdust 3:1, and the moisture content after mixing is about 65%. The raw materials are stacked into a long stack with a height of 0.7m, a width of 1.5m, and unlimited length, and the stack is mechanically turned once a day to maintain the oxygen in the stack. After 4 days of fermentation, the temperature reaches around 70°C. When the pile temperature exceeds 70°C, except for some thermophilic bacteria, most of the harmful bacteria and insect eggs are killed. Continue to ferment for another day, flatten the fermentation piles, let them cool down and stop fermentation. At this time, because the fermentation time is not long, the fibers in the cow dung and sawdust are not destroyed. Because of the high moisture, let it dry for three days to further reduce its moisture to about 30%.

Embodiment 2

[0023] Choose dehydrated cow dung (about 70% moisture) and sawdust (moisture 50%), mix according to the ratio of cow dung: sawdust 1:1, and the moisture content after mixing is about 60%. The raw materials are stacked into a long stack with a height of 0.7m, a width of 1.5m, and an unlimited length; the stack is mechanically turned once a day to maintain the oxygen in the stack. After 6 days of fermentation, the temperature reaches around 70°C. When the pile temperature exceeds 70°C, except for some thermophilic bacteria, most of the harmful bacteria and insect eggs are killed. Continue to ferment for two days, flatten the fermentation stacks, let them cool down and stop fermentation. At this time, because the fermentation time is not long, the fibers in the cow dung and sawdust are not destroyed. Because of the high moisture, let it dry for two days to further reduce its moisture to about 38%.

Embodiment 3

[0026] Choose dehydrated cow dung (about 70% moisture) and sawdust (moisture 50%), mix according to the ratio of cow dung: sawdust 2:1, and the moisture content after mixing is about 63%. The raw materials are stacked into a long stack with a height of 0.5m, a width of 1.0m, and an unlimited length; the stack is mechanically turned once a day to maintain the oxygen in the stack. After 8 days of fermentation, the temperature reaches around 70°C. When the pile temperature exceeds 70°C, except for some thermophilic bacteria, most of the harmful bacteria and insect eggs are killed. Continue to ferment for two days, flatten the fermentation stacks, let them cool down and stop fermentation. At this time, because the fermentation time is not long, the fibers in the cow dung and sawdust are not destroyed. Because of the high moisture content, it was dried in the sun for three days to further reduce its moisture content to about 35%.

Abstract

The invention discloses a semi-fermented padding for dairy cattle lying and a preparation method and application thereof. The semi-fermented padding for dairy cattle lying is mainly made from raw materials including cow dung andsaw dust by mass ratio of (3-1) to 1 through semi-fermentation. It is ensured that fermentation temperature kills harmful bacteria and eggs by controlling the height, width, fermentation temperature and time of a fermentation pile. In addition, due to the fact that the semi-fermentation is not thorough, fiber texture in the padding is kept perfect, the soft comfort degree of fiber is high, caking is not likely to occur, the milk yield of dairy cows can be effectively improved, and the occurrence rate of mastitis of the dairy cows can be reduced.

Description

technical field [0001] The invention relates to the field of dairy cow breeding, in particular to a semi-fermented bedding material for dairy cow breeding, and a preparation method and application of the bedding material. Background technique [0002] Dairy cows in dairy farming will produce about 12kg of dung every day, which will cause the growth environment of the barn to deteriorate, the concentration of ammonia gas will be high, and mosquitoes and flies will breed. In addition, the large amount of cow dung produced by dairy cows will bring huge environmental protection treatment pressure to the cow farm. Therefore, it is particularly important to utilize the waste of cow dung in situ. In cattle farms, cow dung is often used to add other materials to make bedding materials for dairy cows. Bed rest is closely related to cow comfort and directly affects cow production performance and farm efficiency. High-quality bedding and bedding can increase the rest time of cows in ...
