Embryo Inventory

• Sire: The bull whose semen was used to fertilize the donor's egg to produce the embryo. If this column shows Pool, it means that an oocyte An unfertilized egg. was fertilized by IVF In-Vitro Fertilization. In relation to embryo transfers, IVF occurs when oocytes (eggs) are collected via OPU (ovum pick up), and then in a lab, semen is added to create embryos. from a pool containing the semen of multiple sires.
• Donor: TThe female who provided the embryo or oocyte (sometimes referred to as the donor dam).
• Embryo Breed: The embryo breed. Select from the standard list of NAAB National Association of Animal Breeders. www.naab-css.org breeds.
• Fertilization Date: Date the donor egg was fertilized using the sire semen.

• Recovery Type: The recovery type used:

  • Flush is used for embryos
  • IVF for in vitro fertilization (oocytes Unfertilized eggs.)
  • Other for neither of the above
• Tank: The liquid nitrogen storage tank containing the cane with the embryo's straw.
• Incubator: The warming unit containing the embryo's straw or mating.
• Cane: The container holding the embryo's straw.
• Mating: A description of the embryo mating details, such as sire, donor, and fertilization date. May contain multiple embryos.
• Straw number: Number of the straw holding the embryo. Canes contain multiple straws and each straw holds a single embryo.
• From Straw: The first straw number that contains this embryo.
• To Straw: The last straw number that contains this embryo. This allows PULSE to calculate the total number of embryos to be added. For instance, if you add embryos From Straw 6 To Straw 11, a total of 6 embryos are added.
  NOTE: To add a single embryo, do not include From Straw and To Straw values.

• Stage: The stage at which the embryo was harvested:

  • 1 Unfertilized
  • 2 Simple Celled
  • 3 Early Morula
  • 4 Morula
  • 5 Early Blastocyst
  • 6 Blastocyst
  • 7 Expanded Blastocyst
  • 8 Hatched Blastocyst
  • 9 Expanded and Hatched Blastocyst

• Grade: The quality of the embryo:

  • 1 Good
  • 2 Fair
  • 3 Poor
  • 4 Dead (or Degenerating)
• Frozen Date: Date the embryo was frozen.

• Freeze Method: The method used to freeze the embryo:  

  • Direct Transfer (DT) is the process of using high levels of cryoprotectant to quickly cool an embryo to freezing. A common cryoprotectant used for this process is ethylene glycol.
  • Slow is the process of using low levels of cryoprotectant and a programmable freezing machine to slowly lower the temperature of the embryo to freezing.
• Recipient: The animal that received the embryo transfer. Including the Recipient and Transfer details automatically adds a TRANSFER event to the recipient animal. See Import Transferred Embryos for more information.
• Transferred Tech Tech is short for Technician.: The embryo technician who completed the transfer.
• Transferred Date: Date the embryo was transferred to the recipient.
• Breeding Code Bred Code is short for "Breeding Code.": The code associated with the breeding activity. Check your dairy's Breeding Codes for more details on each code.

Interactive column headers allow you to arrange the data into a way that's most useful to you. Depending on the features available for each column, you can add new columns of data, rearrange and reorder them, and filter some columns. To access these features, click on the column menu in the column you want to change.

The top menu can contain three different options—one for resizing the column, one for filtering the data displayed in the column, and one for controlling which columns are displayed. Each menu contains various ways for manipulating what's shown on the page.

Expand the sections below to learn more:

Filter Columns

Columns that contain numeric values can be filtered to show only certain data. For example, to filter the Lactation column so that only animals with a lactation value of 3 display, click the filter option, and then use the fields to create your filter.

Reorder Columns

You can reorder the way columns display by clicking in the header of the column you want to move and dragging it to its new location.

Change which Columns to Display

To add or remove columns from the page, click the columns option and then check or uncheck the boxes to select which columns to display.

You can also remove columns by clicking on the header of the column you want to remove, holding down the mouse key, and dragging the column up and out of the table.
