Insert esophagus or trachea to inject drugs into pigs and be careful.
Pigs often lose their appetite and even do not eat when they get sick, which makes it difficult for artificial forced drug administration. So, how can we solve this problem?
First of all, hold the sick pig and make it stand or lie on its back. Then, use the mouth opener to pry open the pig's mouth and quickly insert the gastric tube into the esophagus along the tongue surface through the root of the tongue. When the position of the inserted gastric tube is correct, the pre-dissolved drug can be injected, and then a small amount of gas is filled into the tube after filling, so that the drug in the gastric tube is emptied. Finally, pull out the stomach tube quickly. It should be paid special attention that the stomach tube should not be inserted into the pig's trachea, so as not to cause the death of sick pigs. The methods to judge whether the gastric tube is inserted into the esophagus are as follows: (1) the compressed rubber ball is connected to the outer mouth of the gastric tube, and the ball remains intact without bulging. After inflating the rubber ball, the gastric tube feels unobstructed, which proves that the gastric tube has been inserted into the esophagus or stomach. (2) if the outer mouth of the gastric tube is immersed in water, if bubbles emerge with the exhalation of diseased pigs, it indicates that the gastric tube is mistakenly into the trachea; if no bubbles emerge, it indicates that the gastric tube is inserted into the esophagus. (3) if the stomach tube is mistakenly put into the trachea, the pig does not bark or the sound is low and weak; if the stomach tube is inserted into the esophagus, the pig's cry remains the same.

The adaptability of chicken bone grass is strong, the soil requirements are not strict, general dry land (flat land, sloping land) can be planted, sandy loam is good, drought resistance, fear of waterlogging, planting land to be well drained, sufficient sunshine. 1, seedling (solar calendar 3~4 months sowing is appropriate), chicken bone grass seed coat smooth and hard, must be treated before sowing, otherwise the germination rate is not high. Treatment method: Mix the seeds with twice the amount of fine sand, put them in mortar holes or bamboo tubes, pound them with round-headed wood for 20 minutes, or rub them with hands for 30 minutes, and sift out the sand.

How to prevent pigs from grinding their teeth at night
First, the feed should be diversified. It is best to feed pigs formula feed, because the various nutrients of formula feed such as minerals, trace elements and so on are reasonable. Concentrate feed should be matched with green roughage, and an appropriate amount of minerals and trace elements should be added, such as adding 1% 2% bone meal and 0.25% 0.5% salt, which has a certain effect on preventing pig molars at night. Once the phenomenon of grinding teeth at night occurs in pigs, each pig is fed with bone meal or eggshell powder, calcium bicarbonate powder 30g, salt 6g, and salt 7g every day.
