Although the concentration of antibodies contained in regular milk is much lower than that of colostrum, it still contains certain antibodies. Most of these antibodies are local antibodies synthesized by lymphocytes of the mammary gland and are not absorbed by the intestine. They can be attached to the intestinal mucosa to prevent the invasion of bacteria from the intestine, and localized. Immune against disease. This is called breast milk immunization. Although diarrhea occurs after weaning, the reasons vary, but loss of breast milk immunity is also an important cause. Maternal antibodies that migrate from the colostrum to the piglet's blood are reduced at a certain rate, and generally lose their protection 2 weeks to 3 weeks after birth. At this time, the antibodies produced by active lymphocyte immunization of piglets are still low, and the concentration is low and cannot be produced. Strong protection, so that at the time of passive immunization of maternal antibodies and active immunization of piglets, there must be immune protection. At this time, the ability of the pig to resist infection is very fragile and it is a very dangerous period. The length of this period is positively related to how much colostrum is eaten. Colostrum eats much and this period is short. In order to allow the pigs to get through this period, letting the pigs eat colostrum is the best way.

Measuring a person`s temperature can be done in several ways. One method to measure a person`s surface temperature is with the use of non-contact infrared thermometers (NCITs). NCITs may be used to reduce cross-contamination risk and minimize the risk of spreading disease. While typically 98.6°F (37.0°C) is considered a [normal" temperature, some studies have shown that "normal" body temperature can be within a wide range, from 97°F (36.1°C) to 99°F (37.2°C). Before NCITs are used, it is important to understand the benefits, limitations, and proper use of these thermometers. Improper use of NCITs may lead to inaccurate measurements of temperature.
