What are the signs of sows before giving birth?

Question: A farmer called to ask, what are the habits and actions of sows before giving birth? What are the signs of sows before labor and delivery?

Luo Wenyi: The sow's customary actions before birth are: The sow is lying and lying and does not like to exercise too much in the days before giving birth. Therefore, the sow should be given a quieter and more comfortable environment. The breeder should be in contact with the sow, and when feeding or cleaning the house, wipe the body of the sow with a hand or brush it with a soft brush to form a conditional reflex that is not afraid of people. Ready. In addition, it is best to put some grass in the pens, so that the sows can make grass nests, and it is also convenient for the breeder to observe the sow's delivery time.

According to the experience of raising pigs for many years, we can use the “three look and one squeeze” method to observe the symptom of the sow's labor: to see if the sows' breasts are inflated and glossy. As the sows are in labor, the breasts are enlarged and shiny. The nipples on the two sides are separated outwards, the nipples show signs of milk dripping, and piglets will be produced shortly thereafter. The second is to look at the tail. Before the sow was delivered, the tail roots were measured for depression, vaginal vulva relaxation, and labia swelling. The third look is to see the performance of sows' labor performance. Before the onset of labor, the sows lost appetite, showed unrest, moved back and forth in the pens, and burrowed in the nest. This behavior usually occurs after about 6 to 10 hours. Sow mucus outflow of the sow, "frequent urination, farrowing to." A squeeze is nipple. Under normal circumstances, sows in the abdomen in front of the abdomen after the emergence of thick milk, about 20 hours or so may be delivered, the middle of the milk out of about 10 hours when the milk can be delivered, the back of the nipple when the milk should be in 3 ~ 6 hours to deliver. However, the above time is not absolute, due to the direct relationship between the breeding sow and the feeding and management, feeding, variety, and body condition. The more accurate method for judging the sow's farrowing time is to squeeze out a lot of milk when gently pressing any sow of the sow, indicating that the sow will be produced immediately.

Vitamin

Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
