Do you know all the signs before the onset of sow disease?
Pay attention to the early warning of reproductive disorders in sows, we need to keep in mind five tips, that is, "viscera around the eyes, blood from hair roots, viscera of auricle, dirty back, cool tip of ear".
We can judge the body condition and health of sows according to the severity of these five phenomena.
The first is the viscera around the eyes. When there are only periocular visceral problems in sows, and there are many periocular secretions and serious tear spots, it indicates that the health problems of sows are in the primary stage. This is mainly due to the liver damage of sows and the accumulation of toxins in the body. This shows that we should beware of reproductive system disorders caused by poisoning in sows, so as not to affect the subsequent reproductive processes such as estrus, mating, fetal development, litter birth, lactation and so on.
Followed by hair root blood, auricle dirty, back dirty. When more and more toxins accumulate in the sow, the pig will experience the phenomenon of pore bleeding, blood spots in the pig ear, back viscera and so on. This is mainly due to the decrease of prothrombin and the rupture of capillaries due to the weakening of liver function. At this time, the sow health problem is already in the intermediate level. Such sows will have low litter rate, return to estrus, abortion and other reactions. In order to avoid the abuse of antibiotics, we should pay attention to distinguish the pore bleeding from Eperythrozoon.
Finally, the ears are cold. When this phenomenon occurs in sows, it shows that the microcirculation of the pig body has been blocked and the blood flow does not reach the end, and the problem is already in a serious state at this time. Sows will appear uterine cold, so that the zygote implantation uterine wall proliferation, mucus secretion weakening, affecting the bed and fetal nutrition supply, just like planting seedlings on the asphalt road, definitely will not survive. Such sows often have a normal estrus, but have a high return to estrus and a low birth rate.
