As we all know, China is a big pig country. So, do farmers know how to increase the survival rate of piglets? In fact, the method is very simple, master the scientific farming methods, the following is a scientific farming method to improve the survival rate of piglets, you can refer to.
    First, the "dairy milk + teaching tank material" piglet nutrition matching model
At present, the feed industry often digging the growth potential of piglets by feeding the piglets to teach the trough, but the weight gain effect of the piglets is quite different due to the difference in the quality of the teaching materials. Therefore, for suckling piglets, the use of the "breast milk + milk substitute + start food" strengthening mode instead of the traditional "breast milk + open food" mode can promote piglet feeding, increase weaning weight and piglet survival rate. For weaned piglets, the change in diet from breast milk to the feedstock reduces the performance of the piglets. The use of the “dairy + feed†nutrient model instead of the traditional “food starter†model allows piglets to be weaned within 1 week. The food intake is significantly improved and adequate nutrition is obtained.
In essence, the model of “dairy product + teaching material†still belongs to the category of feed nutrition, which solves the problem of nutrient absorption. The piglet death problem solves a large part. The piglets are well nourished, the intestines develop well, and the growth and fattening stages grow faster and healthier.
    Second, piglet milk powder liquid feeding mode
The research on piglet milk substitutes began in the 1970s, and foreign pig farms have been widely used. Providing piglets with appropriate formulas at the appropriate time can give full play to the piglets' excellent growth performance and reduce production losses.
The formula concentration of the formula is related to its production process and solubility. Theoretically, the nutritional level of the 20% milk replacer solution is similar to that of the breast milk, but in actual production, due to the production cost and process difficulties, the 1 kg milk substitute is usually equivalent to 0.50. ~0.75 kg of breast milk, it is recommended to prepare an aqueous solution of 10% to 15% concentration. The maximum temperature during dissolution should not exceed 60 ° C, and feed at 37 ° C or so.
The type of feeder is also critical to the effective use of the formula. First, it is necessary to consider the characteristics of the piglets' preference for feeding. Secondly, it is convenient to eat and easy to clean, and to prevent piglet diseases caused by contamination of the milk substitute or equipment hygiene. Feeders should be lightweight, durable, easy to fix, easy to clean and work with workers, usually made of plastic and galvanized metal.
The amount of formula to be fed depends on the age of the piglets, appetite and breast milk supply. The average daily supply of the emulsion is: 1 to 3 days old, 0.5 liter per head; 4 to 7 days old, 1.0 to 1.5 liters per head; 8 to 14 days old, 1.5 to 2.5 liters per head; such as 2 weeks old Starting to add solid feed, the average daily supply of the emulsion can be maintained at 1.5 liters per head until 18 days of age; from 19 days of age to weaning can be maintained at 0.5 liters per day. The number of feedings depends on the use, age of pigs and temperature. It is a complete replacement for breast milk for newborn piglets (within 10 days of age). It is recommended to feed once every 2 hours on a limited basis to ensure The emulsion is fresh and free from contamination. For formulas used as breast milk supplements and weaned transition liquids, the number of feedings is determined based on actual production conditions.
The feeding stage of pig milk replacer powder can be divided into pre-weaning supplement feeding, post-weaning supplement feeding and simultaneous feeding before and after weaning. Feeding before weaning is to feed the piglets with lactation during lactation. The piglets are stopped after weaning. After weaning, the formula is supplemented when the piglets are weaned. The feeding time is generally 7-10 days. Before and after weaning. At the same time, supplemental feeding is to start feeding the milk in the lactating period until 7 to 10 days after weaning. Regardless of whether the milk is added to the milk before and after weaning, the feed intake and daily gain of the piglets in the delivery room can be increased. Supplementing the milk substitute before weaning can improve the health index of the piglet and improve the body condition of the piglet. Supplementary feeding of milk after weaning can also promote piglet weight gain. It is best to add a formula before and after weaning.
    Third, piglet milk powder solid feeding mode
Supplementing the milk substitute in the form of powder can also make up for the deficiency of breast milk. Comprehensive domestic and international experience in the research and production of dairy products, especially before weaning, piglets like liquid diets, the usual way is to add the milk to the water in a certain proportion. Studies have shown that "wet" weaning techniques can help piglets overcome digestive disorders caused by conventional early weaning techniques. However, there are many changes in this method in actual production. For example, there is no special liquid feeding device in pig farms. The influence of temperature difference on the storage time of liquid milk substitutes and water temperature and solubility is whether the whole group is supplemented with milk substitutes or weak. Affirmation of the problem of milk replacer, as well as daily feeding management issues, and so on. In the case of feeding no special feeding facilities, in the form of liquid milk replacer fed to the workload of personnel, is widely used in the actual production is difficult. Therefore, in order to facilitate the management of pigs, pig producers are more inclined to find ways to improve the lactation capacity of sows, but when the sows lose too much weight during lactation, they will affect the reproductive performance of the next stage of the sows. In combination with these practical problems, powder feeding of milk substitutes is a good choice. The specific frankincense contained in the powdered formula can stimulate the piglets' olfaction and make them actively feed, and the nutrient concentration of the powdered formula is higher than that of the liquid formula. In addition, the powder form is convenient for feeding. Feeding workers operate, therefore, feeding the piglet formula in powder form is more conducive to wider research and promotion, and better applied to pig production.
When feeding the milk powder in powder form, the milk replacer powder can be mixed with the teaching material and then sprinkled in the trough to feed the piglets. The ratio of the formula and the grooving material is the best in the ratio of 1:1 (see Table 2). The proportion of the formula added refers to the proportion of the formula in the solid diet of the piglet. Different addition levels of milk substitutes in the solid diet of piglets before and after weaning can significantly increase the daily weight gain of the piglets in the delivery room, improve the feed conversion rate, and improve the humoral immunity of the piglets.
Piglet breeding needs to strengthen aquaculture management, because piglets have weak vitality and are easily attacked by pests and diseases. If improper management can easily lead to piglet death, the above is the key point of scientific breeding to improve the survival rate of piglets. For everyone to learn from.
Ventilation is one of the most important components in a successful greenhouse.
If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
