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 »

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 »

Resistance to heat stress is under genetic control
One of the major factors limiting optimal production and profitability in Florida is heat stress. During the summer, cows experience declines in milk yield of 15 to 20 percent and reduction in conception rate to values as low as 10 percent. Recent research supported by the Southeast Milk Inc. Dairy Checkoff Program indicates that a cow’s ability to regulate its body temperature and prevent the negative effects of heat stress on cow function is determined in part by its genetics. What that means is that it should be possible to select cows genetically that are more resistance to the effects of heat stress. FULL STORY »
