Misunderstanding 1: During the fattening stage, lots of bean cakes or peanut cakes are fed
Many pig farmers have an unscientific concept of feeding, that is, feeding large amounts of bean cakes or peanut cakes during the fattening stage of the pigs. They think that the pigs can grow fast and the meat is strong. In fact, this is wrong. During the fattening phase, pig growth focuses on long fats, not long muscles, and therefore does not require large amounts of protein feed. If a large amount of protein feed is fed during the fattening stage, the pig must remove the nitrogenous part of the protein in the gastrointestinal tract, and other nitrogen-free parts can be converted into fat, but denitrification requires more energy. In addition, the bean cake or peanut cake contains a large amount of unsaturated fatty acids. After feeding more, it can make the fat of the pig soft and yellow, and it will not make the meat strong, but it will reduce the quality of the meat. The market price of cake feed is higher than that of other feeds, and more use will increase the cost of feed, which itself is a waste.
Misunderstanding 2: Feeding pigs with cooked feed
Feeding pigs with raw feed has long been popularized, but many rural pig farmers still adopt the feeding mode of cooked feeds to feed pigs. They think that pigs eat cooked foods tend to grow oil, but this is not the case. After the feed is cooked, the vitamins are almost completely destroyed and the proteins in the feed age and denature. According to statistics, 20% of the nutrients in the process of cooking are lost. The loss of nutrients in the green feed is even greater. If the pot is kept in the pot for a long time during cooking, nitrite poisoning will occur during feeding. The pig died.
Misunderstanding 3: Soup soup
Some pig farmers feed their pigs with water, and the ratio of feed to water is 1:8 to 10, even thinner, and they also feed water to pigs. This method of feeding is very unfavorable to the fattening of pigs. The harm of water feed to pigs is: increase the energy required for water metabolism in pigs, increase the burden on the kidneys; dilute the concentration of digestive juices, which is not conducive to the secretion of digestive juices; accelerate the speed of feed through the digestive tract, thereby reducing the The digestibility of the feed. In order to increase the feed intake of pigs, let pigs eat more and grow faster. Generally, we recommend feeding thick porridge with a feed-to-water ratio of 1:2. We can also feed raw wet mixes with a feed-to-water ratio of 1:1. In addition, sufficient drinking water should be provided.
Misunderstanding 4: The most economical way to feed pigs
At present, there are still a few pig farmers who use drowning to feed pigs and establish long-term cooperative relationships with restaurants. Put the limousine water at home and put it in a built pool for storage. In fact, drowning water contains a variety of pathogenic microorganisms that affect the growth and development of pigs, and some are even fatal. In addition, when drowning water is stored, a large number of pathogenic microorganisms multiply, spread through the flies, etc., can cause losses to farmers, and pig farmers must put an end to feeding drowning water. .
Myth 5: Add antibiotics to feed
Some diseases currently have no effective vaccines to prevent them, especially some bacterial infectious diseases. The use of drugs for prevention has good results. In order to control the occurrence of diseases and promote the growth of pigs, many farmers have added them indiscriminately without understanding the mechanism of antibiotics, posing a threat to food safety and human health. The majority of farmers should establish a concept of safe production with targeted, appropriate, and timely addition of antibiotics.
Do not simply feed the practice to prove that the single use of corn to feed pigs, each 1 kg of weight, need to consume more than 6 kg of corn, but the use of feed to feed pigs only 2.5 to 3 kg of corn, can reduce the cost of feeding.
Protein supplemented feed corn has low protein content and poor quality and cannot fully meet the growth needs of pigs. Therefore, protein feed must be added. You can add 15% bean cake or rapeseed cake to the pig's diet, and add 5% fish meal to the pig.
The vitamin content of vitamin corn supplement is low. When feeding, green feed must be added and vitamins must be added. In the absence of green feed, a variety of vitamins can be added to livestock and poultry.
Minerals supplemented with minerals have a low mineral content and a single nutrient content, so bone powder and calcium hydrogen phosphate, selenium, iron, copper, zinc, manganese and other minerals should be added to the pig diet.
After saccharification and feeding of corn meal, some starches can be converted into sugars after saccharification, and pigs prefer eating fast. Practice: put the corn flour into the tank, then pour 2 times boiling water into a paste to fully paste, and then sprinkle 5 cm thick dry corn flour on the surface, after 3 to 4 hours of corn flour is saccharification.
Before soaking, it should be soaked in corn flour and add 1 to 1.5 times of water to soak for about 2 hours to make corn expand and soften. Pigs are easy to chew and easy to digest and absorb.
