And how do you clean the room, if straw was put under straws?
If for pigs on the floor to choose straw, it is best to use the so-called Canadian technology. It is also called deep bedding technology. It is very convenient in the household, but requires constant monitoring. To do this, a layer of straw is laid on the concrete floor at least 5-7 centimeters. Animals defecate directly on the litter, which absorbs and retains moisture inside.
This layer is not removed completely, but only a new one is placed on top. But this should be done every day and even twice a day, if there are many pigs. However, care should be taken that in certain places the layer is not too wet. For example, animals can ram it or constantly go to the toilet for one place. Here you should remove the entire layer and cover the new one.
On farms, such litter is rarely removed once a year. But, as practice shows, in the household it is advisable to do it more often. For example, once every three months, so as not to create high humidity. This way of keeping is very convenient in winter, as it allows for an additional warming up of the pigsty. But there is too much material consumption.
If you want to use the above method, then you should use the usual manure cleaning. To do this, the animals are expelled to the yard and cleaning is done. The wet layer is removed, the floor is dried and a new layer is covered. It is most expedient to carry out such cleaning once every three days. You can also put sawdust on the lower tier for more absorption of the liquid.
