A.I. & BREEDING

As concerns over falling reproductive performance escalated around the turn of the century, dairy cattle breeders and advisers decided to take on this trend by putting more emphasis on reproduction-related genetic traits (e.g., Daughter Pregnancy Rate [DPR] and Sire Conception Rate [SCR]) and seeking out effective heat detection tools.

Almost all dairy farmers would like to improve the reproductive efficiency of their dairy herd, but they must manage many aspects to achieve this goal, including the nutritional program.

Increase profit. Reduce management inputs. Design a cow that eats less, doesn’t know what a hospital pen is and rarely gets the “open” diagnosis at pregnancy check.

Inventory should be updated every time semen enters or exits the tank. Always ensure hands, gun and all equipment are kept clean and themometer is working properly.

The onset of estrus in dairy cattle is accompanied by changes in physiological activity, rumination and feeding behaviour.

Today, there are many tools a dairy producer can use to influence the rate of genetic change and have lasting effects on the performance of their herd. Over the last decade, the use of assisted reproductive technologies (ART) has steadily increased.
