''Colostrum concentration meter product technical parameters'

ATAGO The Application of Colostrum Gravimeter and Colostrum Concentrator in Feeding and Management of Calves in Pasture ,Can quickly calf serum IgG When the calf was not fed any colostrum IgG Of the content is zero, because the calf is a passive immunization, all of its antibodies from colostrum.When the colostrum fed to determine how or when to collect serum to determine whether the passive immune calf success ?Acquisition time is very important 24 ~ 72 h IgG Content is relatively stable, so in the pasture to calves whether passive immune success, 24 ~ 72 h IgG Blood collection are not any problem, we do not have to be a certain time in a certain time to collect blood and then test IgG Whether the passive immune success IgG achieve 10 mg / mL It will be successful, this is a standard, many cattle can not be determined IgG , Can be used to replace serum total protein, requires more than 5.5 mg / dL Hand - held portable detection equipment (Written colostrum concentration meter )The ranch can be considered equipped.

To control the colostrum Of the quality is very important, ATAGO (Love extension )Of colloidal colloid analyzer, IgG colostrum concentration meter , Can quickly and accurately determine the quality of colostrum.Typically, the preservation temperature of fresh colostrum 0 ± 2Lt; 0 & gt; C (Slightly icing best), nutrient preservation is better, and to prevent microbial invasion of bacteria, frozen colostrum for fresh colostrum is not enough to use, save the temperature of -18Lt; 0 & gt; C, But generally with fresh colostrum (0 ± 2Lt; 0 & gt; C), To ensure quality and reduce the time of the first feeding colostrum.

Colostrum quality testing

Colostrum antibody protein is milk 100Times, ,Colostrum color and other external appearance can only show how much fat content, and can not reflect the level of antibody protein, no matter how experienced staff can not judge the appearance of the merits of the quality of colostrum, the use of colostrum is necessary Colostrum concentration meter of Application of the principle: the serum protein can cause light bending, the higher the protein content, there will be more refraction of the pipeline, the visual area of ​​light is also large area, the same light and dark junction line up, the corresponding reading high.

The colloidal colloid analyzer measures serum total protein content rather than immunoglobulin content. Immunoglobulins are only a part of the total serum protein, while immunoglobulin levels are a real concern. Total protein levels are associated with immunoglobulin levels What is the relationship? 2-8Day calf immunoglobulin and total protein have a close positive correlation.The serum total protein content in calf newborn 2-8Days to reflect the passive immune situation.

Experts have proved through a lot of practice calf serum total protein content threshold is as follows:

◆> 7 g / dl : The calf is likely to be in a dehydrated state (calves are already sick or otherwise)

◆5.5-7 g / dl : Ideal

◆5.0-5.4 g / dl : Threshold, acceptable lower limit

◆<5.0 / dl : Passive immune failure

Colloid quality assessment and feeding volume

Now from the laboratory point of view to determine the quality of colostrum has been very perfect, the monitoring of the instrument is very complete, but from the perspective of the cattle, the quality of colostrum generally have two ways to determine a kind of hydrometer, Is the colostrum, another term called refractometer. Colostrum quality is basically in accordance with the quality IgG The content of the judge, when IgG The content is greater than 50 mg / mL , That its quality is better IgG Of the content below 25 mg / mL When the weight is relatively poor when the hydrometer shows green is better colostrum, if the show is generally not recommended to feed the calf. Refractometer refractive index greater than the general 22%When the general means colostrum IgG Content is higher than 50 mg / mL;If less than 19.9%, We believe IgG Content is lower than 25 mg / mL . In addition, when we use colostrum or hydrometer to measure the quality of colostrum at room temperature must be the case, 20℃ or so.The temperature is too high or too low will determine the quality of colostrum caused a greater impact from the current data, refractometer or colostrum than hydrometer effect better, because the temperature is not limited , So that can directly reflect the quality of the quality of colostrum.Studies show that the proportion of colostrum and immunoglobulin is not associated.
