Reproductive performance of lactating dairy cows is dependent upon service rate (or estrus detection rate), fertility of the service sire, and maternal fertility. FULL STORY »

Assessing ultrasound’s impact on dairy cattle reproduction

Technology continues to revolutionize the way tasks are completed on the dairy, including your ability to get cows bred. One tool that has grown in use is ultrasound. Learn more about how this tool has enhanced dairy reproductive programs. FULL STORY »

Treating dairy cow infertility with intrafollicular insemination

Low fertility in dairy cattle has prompted new research evaluating intrafollicular insemination (IFI) as an alternative to common artificial insemination (A.I.) practices. IFI is based on direct introduction of sperm to a pre-ovulatory follicle. FULL STORY »

Student’s device monitors dairy cows for efficient breeding

The San Luis Obispo Tribune reports a dairy science student at Cal Poly has used a device to monitor a cow’s health and increase pregnancy rates. FULL STORY »

Help to sort through synchronization protocols

It can be a challenge to keep the various synchronization protocols straight in your mind, let alone successfully implement them on your dairy. To help you and your management team more effectively manage your farm’s reproductive performance, a group of dairy reproductive experts have created a dairy synchronization protocol fact sheet. The two-page document outlines established synchronization protocols, making it an excellent resource tool for your reproductive toolbox. FULL STORY »
