1 modulating the misunderstanding of pig feed
1.1 Misunderstanding 1: Fertilization stage to feed a large number of bean cake or peanut cake
Many pig farmers have an unscientific feeding concept, that is, feeding a large amount of bean cake or peanut cake in the pig fattening stage, which is considered to be such that the pig can grow fast and the meat is strong. In fact, this is wrong. During the fattening phase, pig growth is focused on long fats rather than long muscles, so there is no need for 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 consumes more energy. In addition, the bean cake or peanut cake contains a large amount of unsaturated fatty acid. After feeding, the fat of the pig can be softened and yellowed, and the meat is not strong at all, but the quality of the meat is lowered. The market price of cake feed is higher than other feeds, and multi-use will increase feed costs, which is a waste in itself.
1.2 Misunderstanding 2: Using cooked feed to feed pigs
The technology of raw feed and pig feeding has long been popular, but many rural pig farmers still use the method of feeding cooked pigs to pigs. It is considered that pigs eat cooked food and long oil, but it is not. After the feed is cooked, almost all of the vitamins are destroyed and the protein in the feed is aged and denatured. According to statistics, 20% of the nutrients in the feed are lost during the cooking process, and the loss of nutrients in the green feed is greater. If the pot is put into the pot for a long time while cooking, nitrite poisoning may occur during feeding. The pig died.
1.3 Misunderstanding 3: thin soup irrigation big belly
Some pig farmers feed the pigs with water. The ratio of feed to water is 1:8-10, even thinner. In addition, the pigs are supplied with water. This feeding method is very unfavorable for pig fattening. The harm of water feeding pigs is: increasing the energy required for water metabolism in pigs, increasing the burden on the kidneys; diluting the concentration of digestive juices, which is not conducive to the secretion of digestive juices; speeding up the speed of feed through the digestive tract, thereby reducing The digestibility of the feed. In order to increase the feed intake of pigs, let the pigs eat more and grow faster. Generally, it is recommended to feed thick porridge. The ratio of feed to water is 1:2, and the wet mix can also be fed. The ratio of feed to water is 1:1. In addition, adequate drinking water should be supplied.
1.4 Misunderstanding 4: pigs are the most economical
There are still a small number of pig farmers who use drowning to feed pigs and establish long-term cooperative relationships with hotels. After transporting the water to your home, put it in a built pool for storage. In fact, drowning contains a variety of pathogenic microorganisms, affecting the growth and development of pigs, and some are even fatal. In addition, a large number of pathogenic microorganisms are proliferated during storage of water, which can be transmitted to flies and can cause losses to farmers. Pig farmers should stop feeding water. .
1.5 Misunderstanding 5: Add antibiotics
Some diseases have no effective vaccines to prevent, especially some bacterial infections, and drug prevention has a good effect. In order to control the occurrence of diseases and promote the growth of pigs, many farmers have added them indiscriminately, posing a threat to food safety and human health. The majority of farmers must establish a concept of safe production, targeted, appropriate, timely addition of antibiotics.
2 corn feeding pigs notice
2.1 Do not simply feed the
Practice has proved that the use of corn to feed pigs, each weight gain of 1kg, need to consume more than 6kg of corn, while feeding pigs with compound feed requires only 2.5-3kg of corn, which can reduce the feeding cost.
2.2 Replenish protein feed
Corn has low protein content and poor quality, which 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 diet, and 5% fish meal when feeding the pig.
2.3 Replenishing vitamins
The vitamin content of corn is low. When feeding, it must be fed with green and green feed to supplement vitamins. In the absence of green feed, multivitamins for livestock and poultry can be added.
2.4 Replenishing minerals
Corn has low mineral content and a single nutrient composition. Therefore, bone powder and calcium phosphate, selenium, iron, copper, zinc, manganese and other minerals should be added to the pig diet.
2.5 after saccharification and then feed
After the corn flour is saccharified, part of the starch can be converted into sugar, and the pigs like to eat fast. Practice: Put the corn flour into the tank, then pour 2 times the boiling hot water and stir it into a paste. Then sprinkle 5cm thick dry corn flour on the surface and saccharify after 3-4h corn flour.
2.6 should be soaked before feeding
Soak the corn flour in 1-1.5 times of water for about 2 hours to make the corn expand and soften. The pig is easy to chew and easy to digest and absorb.
