Product Description
INTENDED USE
One of the aims of diary cow feeding management is to improve milk
output and shortening the period of no pregnancy.
PRINCIPLE
Detection of pregnancy in dairy cow offers valuable information to
producers. For a long time, dairy cow feeders and veterinarians are
looking forward to simple, rapid and effective early pregnancy
detection method, which is important for improving feeding
management and propagation rate. If the pregnancy is not promptly
detected after mating, it will result in delaying the period of
calving and decrease of propagation rate and milk output. Thus the
cost of feeding management will be increased. If the pregnant dairy
cow can be detected in early period, the cow can get careful
nursing and gestation management, which will increase the pregnancy
success rate. Non-pregnant cow can be hybridized early, shortening
the period of non-pregnancy and decreasing the feeding cost. Thus
propagation rate and economical benefit will be increased. Study on
the diagnostic skill for early pregnancy of diary cow is very
important to the development of the dairy cow industry.
Progesterone (P4) is a kind of steroid hormone. The concentration
change of P4 in milk is one specific characteristic indicating the
activities of cow ovary. The estrous cycle of dairy cow is *1 days
on average. P4 is in low-level at the beginning of the estrous
cycle, thereafter rise gradually, reaches more high-level in middle
period of estrous cycle, P4 level in non-pregnant cow begins to
drop to the lowest level on the *7th day after mating, while it is
still at high level in pregnant dairy cow's blood and milk. This
product is designed and developed on the basis of the estrous cycle
law of dairy cow. It can be performed at the end of estrous cycle.
If only one red line appears, it indicates that the cow is not
pregnant; P4 is in the lowest level at this moment. It is
recommended to make the best use of this time to have the diary cow
mate; If two red lines appear, it indicates the cow is pregnant. It
should get careful nursing and gestation management.
The test theory is based on variation of P4 in the estrous cycle,
to determine whether the early pregnancy of dairy cow by detecting
P4 in the end of estrous cycle .The test strip employs colloidal
gold immunochromatographic technology for early pregnancy diagnosis
of diary cow, with characteristics of high accuracy, easy to
operate, fast result, room temperature storage, easy to carry, safe
to mother and baby cow.
SCOPE OF USE
The test can be used to determine the early pregnancy of diary cow,
reexamine diary cows, and guide the artificial fertilization at
right time.
SPECIFICITY
Specificity: *7.8%
Analytical Sensitivity: 2ng/ml
Sensitivity: *6.9%
Specificity of this test was determined from cross-reaction studies
with FSH (**0μg/mL), E2 (*0μg/mL), PRL (**0μg/mL), LH (*5mIU/ml),
DHT (*0μg/mL), tetraborane (*0μg/mL) and H2O. No cross reactivity
was observed.
HOW TO USE
Because the diary cow’s estrous cycle is ****2days, it is suggested
to perform the test on day *1st after breeding. If positive
results, it indicates the cow is pregnant. It should get careful
nursing and gestation management. Pregnant dairy cow can be
reexamined at any time.
SPECIMEN COLLECTION AND PREPARATION
Take whole milk to test its progesterone level directly. In order
to get reliable result, give up the first three milking and then
collect sample milk around ***0ml. Mix the sample milk well before
testing.
ASSAY PROCEDURE
1. Remove the test device and milk dropper from its foil wrapper by
tearing along the slice.
2. Using the milk dropper, withdraw the milk sample from the
specimen cup and slowly dispense 3 – 4 drops into the circular
sample well. The sample liquid moves slowly to the other end due to
the capillarity. You will see one or two red lines in the result
window.
3. Read results at 5 minutes
Positive: If both T band and C band are visible, the test result is
Positive, which means the cow is pregnant or in middle period of
estrous cycle.
Negative: If only C line is visible, the test result is negative,
which indicates the cow is not pregnant.
Invalid: When control line does not appear on the membrane, the
test is invalid due to improper test procedure or deterioration of
reagents. It is recommended that the test be repeated.
PRECAUTION
(1) Test according to the law of the estrous cycle strictly.
(2) For single use only; do not reuse the test devices.
(3) Don’t keep the strip or cassette in the air for a long time
after unpacking.
(4) While performing the test, make sure that the surface of sample
should not exceed the “MAX” line of strip.
(5) Do not use test kit after expiry date.
VALIDITY AND STORAGE
The period of the validity is *4 months. Store as packaged in the
sealed pouch under the room temperature.
