Some small and medium-sized farmers' pig farms are cemented, clean and easy to clean. The main reason is that they are cheap. It is very common to raise pigs in cement in China. In the process of raising pigs, pigs in cement will also appear. Unexpectedly, in countries where European and American pigs are more developed, the pigs in the cement field are gradually decreasing. Then, why is it not good to raise pigs in cement? Xiaobian will tell the farmers about the disadvantages of raising pigs in cement. Everyone's reference:
1. Violation of the nature of the pig arch
Pigs like to arch the earth because they can get the necessary minerals (calcium, phosphorus, iron, zinc, etc.) from the soil. If the pig houses are all cemented, the pigs can't get trace elements, which may lead to the lack of trace elements. Piglets, especially during lactation, may be thin, anemia, or even death. The underlying cause is iron deficiency.
In this case, we can use a reasonable ratio of feed, or use full-price feed, sprinkle some soil in the corner of the pig house, but clean it regularly.
2, hot summer cold
The cement will absorb heat in the summer, and it will become cold in the winter because of the smaller specific heat capacity. After scientific experiments, the temperature of the cement floor and the mud land will differ by 5 degrees, and the pig has the characteristics of long lying (the piglet is lying for 18 hours every day). ), the cement floor is not too hot to cause heat stress, or it is too cold to cause pig diarrhea, the pig is afraid of cold (pig body temperature conditioning ability is not perfect, the cement floor temperature is lowered quickly, it will cause piglet diarrhea), the big pig is afraid of heat, so It is very detrimental to the growth and development of pigs.
The friction of the cement floor is relatively large. The pigs are active in the cement floor every day. When the time is long, the pigs will become rough and thick. The pigs have no sweat glands. The heat and cold are all done through the skin and fat. In order to resist the cold, The skin of the pig will become thicker, which will also affect the taste of the pork. In this case, weeding can be laid on the concrete floor, so that the pigs often go to the mud land outside the activity, which can effectively reduce the stress.
3, pig leg and hoof disease is more frequent
For the pigs in the fermentation bed, for the free-range pigs, the pigs in the cement field are more likely to find that the pigs have diseased limbs and hoofs. Of course, pigs and hooves that grow in the cement land will not be found in the pigs. A is more prone to wear. If the pig has constipation, the urine is still excreted normally, so the cement floor will slip. If there is a fight between the pigs, it will further increase the probability of the disease. Part of the problem can be solved by making corresponding modifications to the cement house.
