The fishy smell is not equal to the fishmeal in the feed
Some farmers often use the fishy smell of feed to evaluate the content of fish meal in feed, so it is wrong to judge the quality of concentrate. At present, there is a kind of additive called fishy smell in the market. When it is added to the feed, the fishy smell is very strong. Pig farms (households) should realize this.
If a pig sleeps after eating, it doesn't mean that the feed is good
Pigs have certain living habits, especially those under 40 kg. They have certain time to play around noon every day. Sleepy pigs are sleepy because of the addition of sedatives (sleeping pills) to their feed, which destroys their normal physiological functions. The sedatives can reduce blood pressure, body temperature and heart rate of pigs, and affect their normal metabolism. To this end, the state has long had provisions for the feed industry to prohibit the addition of these drugs.
Fecal color can't prove the quality of feed
The evaluation of feed quality depends on feed conversion rate. Some farmers believe that pig manure proves that the feed is good, while yellow manure proves that the feed is bad. In order to meet the psychological needs of the farmers, some feed manufacturers added some substances that had no effect on the growth and development of pigs, such as sodium humate, blood powder and copper above 160ppm, which not only increased the feed cost, increased the burden of the pig farmers, but also had no obvious effect on promoting production.
Pig tail biting is not caused by feed malnutrition
If pigs do not get the necessary nutrients for a long time, such as salt, protein or some vitamins and microelements, they will have Pichia. At present, there are different reasons for tail biting, such as pig density, injection, environmental conditions, light intensity and lack of some nutrients.
