At present, the competition in the feed industry is fierce, the number of feed manufacturers is large, and small feed mills are everywhere. Manufacturers are playing price wars on prices. Small manufacturers are lowering prices with each other, resulting in unguaranteed product quality, but also to cater for farming. The psychological needs of the household, the addition of some additives, led to a lot of problems, the need for the majority of farmers to pay attention.
1. Skin color
In particular, it is easier to observe white pigs. When some pigs are found to be red, they will be "red and purple" in a few days, and many white bubbles appear on the back. These are poisonous phenomena. The pigskins are red and bright, and the eyes are good. Some manufacturers add some additives to the feed, such as organic arsenic preparations, which can promote growth and make the skin rosy in the normal amount of additives. However, if the dosage is too large and the preparation quality is low, poisoning will occur. Pay attention to the observation so that the feed can be changed in time.
2. Stone powder content
In order to occupy the market, the price of various small feed mills has been lowered again and again, resulting in unguaranteed quality. In the preparation of full-price materials, some low-cost raw materials such as millet shells and grass seeds are used. These raw materials have a small specific gravity and a unit weight. The volume is so large that 40 kg of package is not enough 40 kg after filling the feed. At this time, some more important and cheap stone powder is added to the feed to make the weight reach 40 kg, so that the feed has low nutritional value and poor palatability. Farmers can use the following methods to identify: take about 1 kg of feed in the pot, add enough water, stir, after a while, let the stone powder fully precipitate, pour off the water and feed, you can see how much stone powder. Some feed stone powders are not fine enough, and there are many stone powder particles. The right amount of stone powder is needed for nutrition, but if the amount is too high, it will affect the quality.
3. Fecal state
The normal state of pig manure should not be hard or hard. The softening of the floor is due to the influence of diarrhea on piglets and the low survival rate. Feed manufacturers and farmers pay great attention to this problem. For this reason, drugs for preventing and treating diarrhea have been added to the feed. Such as antibiotics, antibacterial drugs, etc., played a very good effect. However, the amount of the additive is too large to make the stool hard and spherical, which is also a manifestation of indigestion. Long-term use causes the pig to grow slowly. Some farmers think that it is good to not diarrhea, and some farmers suffer from the death caused by pig diarrhea, and they will not hesitate to buy such feed at a high price, causing economic losses.
Regarding the color of the stool, it is not possible to judge whether the quality is good or not depending on whether it is black or not. At present, some farmers think that black manure is a good material and the digestibility is high. There is no scientific basis. In order to cater to this understanding, some manufacturers add a large amount of additives to make the feces black, such as copper sulfate, ferrous sulfate, etc., normal addition is suitable for pig growth, a large number of long-term use, can lead to chronic poisoning, accumulation in the body In general, environmental pollution, etc., the feces are black, may be good, may not be good, can not judge the quality according to the color of the stool.
4. How much sleep
Under normal circumstances, the big pig rests on a daily basis, not in a state of sleep, and when it is slightly alarmed, it will rise. The pig is lively and active, which is good for health and growth. However, there is a misconception in the farmers that they think that they can sleep and grow fast. In order to cater to this understanding, some feed mills add sedatives to the feed, which is not good for pig growth and development, especially for pigs. Such as reduced exercise, decreased physical fitness, slow estrus, decreased ability to breed. At the same time, the state prohibits the use of sedatives for residues in meat. Therefore, the majority of farmers need to pay attention.
5. Protein content
Regarding what kind of feed to buy, it should be based on the breed of the pig and the management conditions of the feed. It is not the higher the protein content and the higher the price. For example, ternary hybrid lean meat growth and fattening commercial pigs, if the pursuit of high lean meat rate, can use about 16.5% of protein containing feed, if the pursuit of high growth rate, you can use about 15% of protein containing feed. For the vast rural areas, most of the pig breeds are mixed-use pigs, and it is not necessary to use high-protein feed. In order to pursue growth, we can refer to the following three stages: 16% for piglet crude protein, 14% for medium pig, and 12.5% ​​for large pig. However, it should be noted that the protein content of some manufacturers does not match the actual value, and often does not reach the standard value. In the use, attention should be paid to observation and identification.
