First, hybrid pigs cannot be used as breeding pigs.
This is because the hybrid pig is large in size, good in physique and fast in growth. However, because its genetic performance is extremely unstable and used for breeding pigs, its offspring will have severe segregation of traits, such as reduced feed remuneration, slow growth, and resistance to disease. Ability to weaken and so on. Therefore, hybrid pigs cannot be used for breeding pigs.
Second, pellet feed mixed with water.
In practice, some pig farmers like to mix granules with water to form porridge for pigs. This is unscientific. Because of the water content of the feed pellets, its nutrient composition will be severely damaged and its nutritional value will be greatly reduced. The correct method is to drink dry water first.
Third, the pig eats sleep and shows good material.
Pigs have a certain living habits, that is, eating, activities, and rest. Especially for pigs under 40 kg, there must be some play before and after noon every day. Sleeping after eating may be a tranquilizer (such as chlorpromazine) added to the feed. After the pigs eat the feed, their normal physiological functions are destroyed and the pig sleeps due to anesthesia. At the same time, sedatives have a role in lowering blood pressure, lowering body temperature, and reducing the number of heartbeats that occur in pigs, affecting the normal metabolism of pigs, and there are residues of tranquilizers in pigs, which is extremely detrimental to consumer health.
Fourth, the feed taste is of good quality.
Some pig farmers tend to assess feed quality based on the size of feed odors. This is not correct. If there is a kind of additive called *** in the current market, it will be very rich in fishy smell when added to the feed. It reminds pig farmers to take notice of this and prevent them from being deceived.
5. Black pig manure indicates good feed quality.
To assess the quality of feed quality depends on the level of feed conversion. The normal color of the feces is determined by the composition of the feed intake and the digestion and absorption capacity of the pig. Some pig farmers think that the feed for pork chops is good, and the feed for yellow feces is not good. This is wrong. It is precisely because of this misconception that some feed manufacturers add substances that have little effect on pig growth and development in order to cater to the wrong psychology of pig farmers. For example, copper sulfate makes black feces and increases feed. The cost has greatly increased the feed price and also increased the economic burden on pig farmers, but it has no obvious growth-promoting effect on pig growth and development.
Sixth, the pig's fur is bright and the feed is good.
Some pig farmers think that the pig's skin is red and the feed is good. The skin color of the pig and the brightness of the fur are determined by the amount of nutrients in the feed, mainly proteins, fats and vitamins. Some feed manufacturers increase the content of selenium and copper in the feed, making the pig's skin red, but there is a large amount of selenium and copper left in the pork, and eating such pork will cause serious harm to the human body.
Seven, the pig bite tail nutrition is incomplete.
Under normal circumstances, pigs that have not obtained essential nutrients for a long period of time may experience pica, such as salt, protein, or lack of certain vitamins and trace elements. However, the feed produced by regular manufacturers will not be seriously inadequate and there will be no phenomenon of different foods. Pigs also bite the tail due to the following reasons: the density of the pigs is too large, the environment of the pig house is poor, the light intensity is high, and some nutrients are lacking. Biting pigs are often between 10 and 40 kg body weight, and pigs weighing around 20 kg are particularly severe, and suckling piglets or pigs over 40 kg weight rarely occur. Pigs weighing between 10-40 kg are the only weapon to attack the pig during the hilarious stage. The only attack weapon of the pig is the mouth. The beginning of the tail biting is for the sake of play. When the blood is bitten, it becomes the hobby of the same pig. Pigs bleeding on the tail, out of curiosity, licking or arch bite, this is one of the important causes of tail biting. This situation occurs in response to wounded pig segregation, while piglets should be tailed.
