Farmers' Misunderstanding of Pig Feed Quality
1. Pigs have a certain living habits, that is, eating, activities, rest, and sleeping. In particular, pigs under 40 kg must have a certain amount of play and joy before and after noon every day. Sleeping after eating is due to the addition of a sedative (hypnotic) to the feed. After eating, the pig breaks normal physiological functions and sleeps under anesthesia. The sedatives will have a three-reducing effect on lowering blood pressure, lowering body temperature, and lowering the number of heartbeats on the body, affecting normal metabolism, and such drugs have residues in the body and are harmful to the human body. For this reason, the country's feed industry has long been forbidden to add.
2, thick fish flavor does not mean that the fish meal in the feed plus. Some pig farmers tend to assess the amount of fishmeal in the feed and the quality of the concentrate based on the fish smell in the feed. This is not correct. In the current market, there is a kind of additives called fish musk. Adding to the feed makes fish smell very strong, reminding pig farmers to realize this.
3, fecal color does not mean the quality of the feed. 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 black feces is good, and the feed for yellow feces is not good. In order to cater to the hearts of pig farmers, some feed manufacturers have added substances that have little effect on the growth of pigs, such as humic acid and more than 160 mg/kg of copper, to increase feed costs and increase the burden on pig farmers. Without obvious growth-promoting effect.
4, the color of the pig's skin can not represent the quality of the feed. Some pig farmers think that the pig's skin is red and the feed is good. Pig skin color and capillary brightness are determined by the amount of nutrients in the feed. Mainly proteins, fats, vitamins, etc. Some feed manufacturers increase the content of selenium and copper in the feed to make the pig's skin red, but there are a lot of selenium and copper in the pork. We know that selenium and copper are toxic substances. People who consume high-selenium, high-copper pork are seriously harmful to the human body.
5, pig tail biting does not mean that the nutrition in the feed is incomplete. If pigs do not get necessary nutrients for a long period of time, pica can appear. Such as salt, protein, or certain vitamins and trace elements. However, the manufacturers who normally produce feed normally do not have serious shortages of these substances, and there will be no phenomenon of different foods. What is the reason for tail biting? At present, many pig experts have different opinions. Such as the density of the pigs, the environmental conditions of the piggery, the light intensity problem and the lack of certain nutritional problems. However, on-site observation, biting pigs more than 10-40 kg body weight. Pigs with a body weight of about 20 kg are particularly severe, and piglets that are lactating or who have more than 40 kg of body weight rarely occur.
