First, the ills of the cement floor, here I say three main drawbacks 1, lack of nutrition: the cement floor is relatively hard, the ingredients inside the pig can not shake, all the nutrients can only be provided by breast milk and feed, easy to make part of the lack of nutrition. For example, the sows’ milk is prone to iron deficiency. When pigs are raised on the land surface, the piglets can obtain iron from the soil by biting the soil. However, iron cannot be supplemented on the concrete floor, and iron must be manually supplemented. Do not underestimate this point of iron, China in the 1970s a lot of imitation of foreign pig construction, many large farms use concrete floor, there has been a special kind of disease, piglets during breastfeeding, weight loss, anemia, and finally a large area of ​​death; For the first time the disease was discovered, only the cement floor was there but the land surface was not. At that time, people named it as "cement disease." Later, after the study, it was caused by iron deficiency. After a variety of iron supplements were adopted, this problem was solved. In addition, the soil can also provide a variety of nutrients, if we pay attention, other pigs in the earth ring are often stronger than the pigs in the cement ring; pigs on the cement floor may also lack other nutrients, but only a short time for pigs. There is no obvious symptom. Therefore, if you are raising male sows in the cement ring, you must consider the lack of nutrition. 2. Hard and easy to hurt limbs and hooves: We all have experience. Running or playing on concrete grounds for a long time is very easy to cause joint pain. This is because the ground is too hard and it lacks elasticity. Compared with pigs, pigs have smaller legs, smaller hoof areas, and larger pig weights, making it easier to injure limbs and feet. In the past, when China imported advanced varieties, a large number of Danish Landrace pigs were introduced. However, after the arrival of domestic animals, a large number of outbreaks were caused due to the onset of limb and leg diseases; the reason for the final investigation was that this species had more fine legs, a long body, and a high lean percentage. Legs and hooves cannot often bear excessive weight. In foreign countries, they don't use cement floor alone, and they all take preventive measures. Later in China, they have been considering leg firmness to avoid this The situation happened again. Now, there are still a large number of breeding pigs on imported pig farms because of the limbs disease, especially the high lean boars. High thermal conductivity, not conducive to thermal insulation The concrete floor has a higher thermal conductivity and a poorer thermal insulation performance compared to brick and land; this is not a big impact on the big pigs, but fatal to the pigs. One of the characteristics of pigs is that “big pigs are afraid of heat and piglets are cold.†Large pigs are afraid of heat because pigs lack sweat glands and cannot rely on sweating to dissipate heat. Moreover, big pigs wear a thermal underwear all year round (in vivo). Fat), and the pig's coat (hair) is not warm, underwear has not been created, is the most cold. If the temperature is insufficient, the disease resistance of piglets is greatly reduced, and various diseases are prone to occur. The cement floor belongs to the cool ground, which means that the heat conductivity is strong. The heat of the piglets allows the cement floor to suck away, and it is easier for the cold to have problems. According to scientific research, pigs lie on cement floors, and the effective temperature is 5°C lower than the actual air temperature. In the case of grass or wood, the effective temperature can be 5°C higher; that is, the same temperature is 20°C. The pigs are Lying on a matted ground will not feel cold, because the effective temperature will increase; while lying on the concrete floor, it will often feel cold because the effective temperature is lowered. The above hazards do not mean that the cement floor cannot be used, but that we know the hazards of the concrete floor and we can take appropriate measures to prevent and solve it. The following methods are available for reference: Second, the solution 1, the use of full-priced feed: If the pig needs nutrition can be met through the feed, there will be no lack of nutrition, with particular attention to vitamins and trace elements. Now people are using compound feeds, nutrition should be sufficient, but also pay attention to some issues; if the feed is stored for a long time, part of the nutrients will easily fail, it may cause lack of this nutrient; In addition, the feed formulation is detailed The formula can not be arbitrarily changed, so if you do not understand the characteristics of various feed ingredients, do not easily change the formula, or reduce the amount of material (or premix). 2, to supplement easily lack of nutrition (primary iron, fill green feed, red clay, coal cinder, etc.): In the previous mention of full-priced feed, but the full price of feed sometimes there will be a lack of nutrients, it needs to be artificially compensated. There are several main places: First, suckling piglets must be iron supplemented, because the iron in the sow milk can not meet the needs of growing piglets, conditional can directly fill the iron needle, without conditions can also sprinkle some of the pigpen Without contamination of the new soil, piglets will add their own food. Second, breeders are prone to lack of nutrients. They may consider supplementing green feed, and they may also sprinkle some new soil or coal cinders into the ring. There is another question here. Why should the male and female pigs make up without considering fat pigs? Because nutrient deficiency is often the accumulation of quantity and time, the feeding period of fat pigs is very short, and some nutrient deficiencies do not show a lack of symptoms; male and female gilts have a long feeding time and lack of nutrition can cause obvious symptoms. For example, vitamins are called biotin. When pigs are poor, there are no symptoms. When raising sows, however, there is a hoof crack. In the end, because of hoof pain, it is difficult to walk and cannot be normally produced. 3. Soft ground in the circle (out-of-home activities): Some pig farmers have cement floors, brick floors or land surfaces in the pigsty, which can reduce the problem of excessive cement floor; Soft ground activities outside the home can also alleviate the problem of excessive ground. If broilers are bred, this issue must be taken seriously. Ground and floor heating: The problem with cement floors is that the heat transfer is quick and the pigs are afraid of cold. However, if the concrete floor is close to the pig's body temperature, there will be no temperature difference. Building a floor or floor heating is a measure to increase the temperature of the concrete floor. The mantle is a part of the barn ground built into a mantle, the following is the fire, in the fire up the fire, you can increase the temperature of the cement floor, which is the use of the principle of the use of fire pits in rural people; another approach is to design cement If it is difficult to change the ground, you can lay heating pipes on the concrete floor. The water pipes are covered with a layer of cement. When it is necessary to warm up, use a water-heating boiler and a pressure pump to make the laid pipes perform hot water circulation. The method of temperature increase. This is a good way to do this. Even if the temperature is low, the pig will feel comfortable if the ground is hot. According to this principle, many pig farms have designed an inexpensive piglet incubator to adjust the temperature through a temperature sensor. This is a cement incubator designed in a pig farm in Anhui Province. The bottom is a cement surface, under which there are electric heating wires and a temperature sensor on the side, just like our common air conditioners. For example, when the temperature is controlled at 35-40°C, heating starts at less than 35°C, and heating stops at 40°C. The effect is very good and the price is low. Bedding: Bedding is a cost-effective and practical way to deal with the concrete floor. As long as it is a good insulation material, such as wood, crop straw, sawdust, random cloth, etc., you can choose according to the specific circumstances, people This is often the case with pigs raised in fermented beds. In the picture below, sawdust is laid high on the ground. Pigs are very comfortable in such an environment. 6, bundle tied firewood insulation: This method is to tie the firewood into bundles, hanging up vertically, these fireweed is also equivalent to insulation wall, but it does not affect the pig's activities, which can also prevent firewood and urine mixed, It is a method commonly used by farmers for raising pigs. 7. Raise the temperature in the house: If the house temperature is high, it will also reduce the impact of the cement floor; for example, if the temperature required by the pig is 25°C, and we supply the pig with 30°C, then the 5°C that eliminates the effective ground temperature drop is eliminated. It is also 25°C, which is the temperature that pigs need. In this way, the concrete floor is not only harmless, but it is beneficial. 8, built a small room: in a large circle to build a small room, can make the local temperature rise, suckling piglets incubator is this principle. Because pigs need a local environment. For example, a pig house is a small environment relative to the outside world, and a small room built is also a small environment relative to a pig house. For humans, the smallest environment is human clothes. In cold weather, wearing a fur coat will not be cold. But pigs can't wear clothes. Small rooms are the smallest environment for pigs. Keep dry: Keeping dry is also a measure to reduce the cold impact of the cement floor, because the dry concrete floor lowers the effective temperature by 5°C, while the wet concrete floor lowers the effective temperature by 10°C because the water absorbs heat when it evaporates. . Therefore, in the season when insulation is needed, it is necessary to strictly prevent ground watering.
