The darker the feces, the better. Many farmers think that if the feed is good, it's not black. This argument makes some sense, but it is not entirely correct. The correct method of identification is: take a look and smell. Not only look at the color, but also the degree of moisture, hard or dilute water samples are abnormal. In particular, we must pay attention to the presence of undigested corn and rice cake granules, and then smell the smell. If there is undigested granules in the Stool, it can be confirmed that the digestion of the feed is not complete, and the feed formulation may be irrational. If the recipe contains a little more bran, vegetable vines, etc., the animal excrement will be black. In addition, high copper can also cause fecal blackening, but high copper can only act as a fecal black (ie, copper content of 125 to 250 mg/kg) only if it is several tens of times higher than required, if the copper content exceeds 250 mg/kg. , it will cause pig poisoning. Red skin is like red skin is divided into normal red and drug red. Artificially add aphanelic acid in the feed. Individual unscrupulous manufacturers even directly add red arsenic or white phosphorus, which will also make the pig's skin ruddy. The main purpose of adding aphanelic acid is not to make the pig's skin red, but to use its antibacterial growth to promote long, in the low dosage, there is sterilization, antibacterial, prevention of dysentery and promote growth. If blindly increasing the dose to achieve skin redness, arsenic poisoning occurs in pigs. Can pigs eat or sleep? Many farmers believe that it is good for pigs to eat and sleep. As a result, many illegal manufacturers add sedatives and other prohibited drugs to the premix. In fact, the so-called eatable, that is, palatability problems (love sweets is the nature of the pig), but the pig can absorb the nutrition every day is a certain, eat too much can not be absorbed, it can not be converted into energy or fat It can only lead to waste of resources and increase costs. So instead of eating as much as possible, as long as the pigs eat nutrient balance, it will be very quiet. If the stocking density is too high, the premix ratio is unscientific, or the pig’s nutrient intake is improper or unbalanced, suffering from skin diseases will make the pig excited and restless. It is not advisable to add stability and libai equal hypnotic drugs to make pigs sleepy. Many farmers believe that there are clearly visible particles in the premix that are good products. Actually, the visible feeds for pellets are often unpretreated raw materials. The solubility and absorption of these large-grained raw materials in the gastrointestinal tract are worse than those after treatment, and are not easily absorbed. Excessive amounts can easily cause pigs. The adverse effects even poisoned.
