Application Place:

Press the label onto the hair across the backbone, between the hip and the tail head.

Application Procedure:

Apply the label 25 days after calving.

Labels can also be used after insemination to identify three weeks returns and for others productiveness managements uses.


  1. Storage:

    Keep the labels warm 15 - 20 minutes before application. Place them in a polystyrene box with a warm pack and/or a bottle with hot water, or in your clothing near your body. Perfect temperature is 37º (human body temperature). These methods activate the adhesive and are essential for optimum performance product. Kept under these conditions, the product can be applied in all seasons.
  2. Cleanness:

    Remove the loose hair with a brush vigorously and then clean the area with a cotton cloth. The hair must be dry and free of dust and oil.
  3. Stick it on!

    1. Stick the label on from one end to the other.
    2. Press the label firmly onto the hair along its whole surface by rubbing the hands backwards and forwards over it to allow the adhesive to penetrate the animal hair. 
    3. With the edge of the hands press the ends down firmly.
    4. With your fingertips press the label and make sure it sticks properly.

    Stick the label during midday or afternoon, so you make sure the hair is not wet.

  4. Visualization:

    The product is ready to detect mount activity. The bright layer underneath (blue, fuchsia, green, orange or yellow) will begin to reveal after the first mount. The animal must be inseminated after several mounts, when more of the bright signal layer is revealed.

Aditional Information:

  • During fly season, the label needs to be applied nearer the top of the tail head so tail flicking does not damage the rub-off surface.
  • For smaller cows, stick the label slightly forward of normal.
  • During winter trim long hair if necessary, leaving 3 cm minimum.
  • Best to not apply in rain.
  • The label will stay in its place for weeks if applied properly by following the steps above

Way of use:


Use the same colour of label (eg: orange) for the first application. When FASCO AP  detects true mount activity / standing heat, you have to inseminate the animal and change the label for a new one (eg: fuchsia) to verify the results of the insemination. If the second label is not scratched after 21 days, the animal has been correctly inseminated. But if the rub-off surface is scratched, the animal has repeated and was not pregnant.

Option A: On day 8-9 after starting the AI protocol, apply FASCO AP  labels with the end of the application of hormones. Then only inseminate cows recorded mounting activity / oestrus.
Option B: In the re-synchronization or review of oestrus in the return, apply FASCO AP  labels  at the time of use of CIDR (controlled internal drug release intravaginal insert containing progesterone) in animals that were not pregnant. Then re-inseminate only cows that accuse mounting activity / oestrus in FASCO AP  labels. At this point, change FASCO AP  labels of the re-inseminated animals with a new one of another color to certify in the next days the labels may not detect mounting activity by pregnancy.

Applying FASCO AP  labels along with hormones in all cows released into service, you will be able to increase their rate of heat detection (without any decrease in conception rate) without difficulty. It is very useful the combined use of FASCO AP  labels and hormones.

Before moving the bulls with the cows, streamline the management of your herd applying FASCO AP  labels and select the animals showing the First Heat!

AP - Productivity Management System

Orange: Used to identify cows that have never been served. Once they have been served remove the label.

Green: Used to identify problem cows. Apply to cows which are found not to be pregnant, where you need to get them served as soon as posible.

Yellow: Used to identify three weeks return. Labels must be applied two weeks after service. If these repeat heats are missed you will have to wait another three weeks or wait until your vet confirms the cow is not pregnant.
Fuchsia: Used to identify cows which have had vet treatments for fertility.
