What should I do if the gilt is not estrus?

The reason why the sow does not have estrus is more complicated. The reasons are as follows: 1 mature and immature; 2 years old and aging; 3 genital diseases; 4 systemic diseases; 5 endocrine disorders; 6 nutrition, trace elements and vitamins Lack of; 7 environmental temperature is too low or too high, light is too weak and other stress factors. All of these can cause sows to lose their estrus. If the sow is not estrus for a long time, appropriate treatment measures should be taken for the reason that the sow is not estrus. 1 Strengthen feeding and management, properly increase concentrates, feed feed rich in inorganic salts and vitamins, increase exercise and improve feeding environment. 2 suffering from genital diseases, common in ovarian and uterus diseases caused by heat, should take the appropriate treatment for different diseases. 3 Induction of estrus, during the estranged period of the sow, the use of exogenous hormones to promote their estrus and breeding, shortening the reproductive cycle of sows. Among them, gonadotropins (such as aphrodisiac, intramuscular injection, 10 ml per pig) can cause ovulation in the estrous period of the sow. In addition, oestrogen injections to sows and the use of chorionic gonadotropin or maternal serum also allow ovulation of sows.

Flask

Conical culture flask (referred to as shake flask) is an ideal choice for medium configuration, mixing, and storage, which is mainly used to cultivate cytoplasm to oxygen-demand, which can also be used to cultivate bacteria, fungi, and plant cells in suspensions.

The shake flask is made of medical grade PETG, which is in line with the requirements of contact management requirements to avoid bisphenol A;
Products are made of independent vacuum packaging, easy to use, avoid cross-infection;
Bottle body seam,
One-time blow molding, avoiding surface scratches or cell hit crackers;
The surface finish reaches the mirror requirements, and the permeability is close to the glass, which reduces the risk of cellular wall;
The bottle mouth is in line with the international SBS standard, suitable for the shortcut connection of the bioreactor;
Using electron beam sterilization, SAL = 10, ensures ⽆ DNase / RNASE, no thermal, non-toxin.
It is equipped with 0.2 ㎛ ㎛ ⽓, can better mix the cells and culture fluid, increase the empty transmittance, so that the cells can be longer to more density.
5L culture bottle handle design for easy design, avoiding the risk of pollution during the use of the bottle mouth during use
2.8L Cultivate the bottom optimization of the bottle, saving usage space, greatly improving the usage rate of shaker, reducing customer development and production costs
Bottle of ⾝ uses the extrusion process technology, the bottle is smooth, and the cellular wall and culture liquid are reduced.
Adding electron beam irradiated, sterile independent packaging is convenient.
