ΤΕΣΤ ΕΓΚΥΜΟΣΥΝΗΣ ΓΙΑ ΑΓΕΛΑΔΕΣ ΤΥΠΟΥ CP250

ΠΕΡΙΓΡΑΦΗ

Poor reproductive performance is one of the most costly and difficult problems for dairy and livestock producers. Even in some well-managed herds, reproductive failure continues to be one of the primary reasons why cows are culled.

Depending on the level of milk production in the herd and variable costs associated with poor reproductive management, a dairy producer loses between $1 to $3 per cow each day the cow is open (not pregnant) beyond the 90 days postcalving.

Inaccurate or inefficient heat detection is still the major cause of low conception rates and long calving intervals. But there is a tool to help herd managers and veterinarians troubleshoot causes of poor reproductive performance--especially problems associated with heat detection. The tool is milk or blood progesterone analysis. Milk samples have been tested by scientists for many years to monitor progesterone levels in cattle. Thus, we manufacture this test kit to help the farmer/dairy owner to increase their reproductive management and profitability.

ΕΝΔΕΙΞΕΙΣ

Recommended to confirm estrus, detect pregnancy, improve controlled breeding, define cycling, diagnose infertility disorders, and to monitor fertility treatment

ΠΡΟΟΡΙΣΜΟΣ ΧΡΗΣΗΣ

Progesterone(P4) is a steroid hormone and regulates ovulation in female mammals. The concentration of progesterone in blood and in milk is in accordance with the reproductive cycle of the individual female. When items related to reproduction need to be addressed, an assay of progesterone is often the method of choice. In the dairy industry, progesterone tests in bovine milk are used as a non-invasive method for determination of the reproductive status of the cow. To minimize user handling, the format of a dry reagent assay is chosen. This format can be automated, gives results fast, and investments and disposables are low-cost. These requirements are obligatory as preferably these test are performed at every milking. If cow conceive, the progesterone present in high peak from day18 ~ day22, then detect pregnancy at this period to get result fast and reliable.

ΧΑΡΑΚΤΗΡΙΣΤΙΚΑ

  1. Identify "open cows" as early as 23 days post insemination
  2. Reduce costly "Days Open"
  3. Reduce pregnant intervals
  4. Increase conception rates by making a better breeding decision
  5. Screen for ovarian dysfunction
  6. Improve an embryo transfer practice
  7. Eliminate guess work from qualirative tests

ΑΠΟΔΟΣΗ

Perform the test 23 day post insemination .Testing on other days lead to wrong results due to variations of progesterone labels which varies in different stages of reproductive cycle.

ΔΙΑΔΙΚΑΣΙΑ ΤΟΥ ΤΕΣΤ

1. ΣΥΛΛΟΓΗ ΔΕΙΓΜΑΤΟΣ

Milk samples should be obtained preferably from the foremilk or milk jug and put into a clean container. Last milk can be used, but is less preferred. Test milk within 30 minutes after collection.

2. ΔΟΚΙΜΗ

Take 2-3 drop sample milk into the sample pad of the test strip or put the the sample pad of the test strip into the sample milk, read the results in 5 minutes

ΑΠΟΤΕΛΕΣΜΑΤΑ

Positive:two lines appears
Negative: only Contol Line appear
Invalid: no lines appear, or only Test Line appear

ΑΠΟΔΟΣΗ ΤΟΥ ΤΕΣΤ

We completed the evaluation in 635 cows in four dairy farms, and used the Rectal Palpation Method to reconfirm the pregnant/non-pregnant cow. Used the CowPreg Test to detect 515 cows, and 499 cows were positive results, the accuracy 96.9%; used the CowPreg Test to detect the nonpregnant cow, total 120 cows, and 117 cows were negative results, the accuracy 97.5%.
