Pig feed is the basic substance for the growth and development of pigs. The quality of pig feed is related to the health and growth rate of pigs. Therefore, when feeding pigs, you should pay attention to the following misunderstandings about the quality of pig feed and correctly identify them. Pig feed quality.

01

Pigs have a certain life Habits

That is, eating, moving, resting, and sleeping. Especially piglets under 40 kilograms must play and fight to a certain extent around noon every day. The reason why pigs fall asleep after eating may be because a sedative is added to the feed, which destroys normal physiological functions and causes the pigs to fall asleep under anesthesia. Sedatives have three effects on the body: lowering blood pressure, lowering body temperature, and lowering heart rate, affecting normal metabolism. Moreover, these drugs have residues in the body and are harmful to the human body. For this reason, the country has already stipulated that additives are not allowed in the feed industry.

02

A strong fishy smell does not mean that too much fish meal is added to the feed.

Some pig farmers often use the fishy smell in the feed to evaluate the fish meal content in the feed and the quality of the concentrate. This view is wrong. There is a flavoring agent called fishy fragrance on the market. When added to the feed, it will appear to have a strong fishy smell. Pig farmers are reminded to be aware of this.

03

The color of feces does not represent the quality of feed.

Evaluating the quality of feed depends on the feed conversion rate. The color of feces is normally determined by the composition of the feed and the digestion and absorption capacity of the pig. Some pig farmers think that feed that discharges black feces is good, but feed that discharges yellow feces is not good. In order to cater to pig farmers, some feed manufacturers add substances that have little effect on pig growth and development, such as fertilizer humic acid and copper above 125 mg/kg, which increases the cost of feed and increases the cost of pig farmers. burden without obvious growth-promoting effect.

04

The color of pig skin does not represent the quality of the feed.

Some pig farmers believe that if the pig's skin is red, the feed will be good. The color of pig skin and the brightness of hair tubes are determined by the nutrient content in the feed. Mainly protein, fat, vitamins, etc. Some feed manufacturers increase the content of selenium and copper in the feed to make the skin of pigs red. However, a large amount of selenium and copper remain in pork. We know that selenium and copper are toxic substances. , people eat pork high in selenium and copper, which is seriously harmful to the human body.

05

Tail biting by pigs does not mean nutritional deficiencies in the feed.

If pigs do not get necessary nutrients for a long time, they will develop pica. Such as salt, protein, or certain vitamins and trace elements. However, for regular feed manufacturers, these substances will not be seriously insufficient, and there will be no phenomenon of pica. What is the reason for tail biting? Currently, many pig experts have different opinions. Such as pig density problems, pig house environmental conditions, light intensity problems and lack of certain nutrients, etc. However, on-site observation showed that most tail-biting pigs weigh between 10 and 40 kilograms. Tail biting is particularly serious in pigs weighing about 20 kilograms. It rarely occurs in lactating piglets or pigs weighing more than 40 kilograms.
