The determination of open cows in modern dairy farm is important for several reasons, which are mostly based on economic considerations. For examples, first, open cows are unproductive and costly to maintain. They consume feed and resources that could be used for pregnant cows or replacement heifers. Secondly, open cows reduce the number of calves that can be sold or retained each year. This affects the income and profitability of the cow-calf operation. Besides, open cows indicate a problem with the reproductive performance of the herd. This could be due to poor nutrition, disease, genetics, or management factors. Identifying and culling open cows can help improve the overall fertility and efficiency of the herd.
There are different methods to determine the pregnancy status of cows, such as palpation, ultrasound, blood tests, or milk tests. Each method has its advantages and disadvantages in terms of accuracy, cost, convenience, and timing. The best method depends on the availability of a veterinarian or technician, the size and type of the herd, and the goals and preferences of the producer.
Pregnancy checking should be done as soon as possible after the breeding season to allow for early culling decisions. This can save feed costs and improve cash flow. It can also help plan for future breeding and calving seasons. Knowing when the cows are conceived can help estimate their calving dates and manage them accordingly.
Pregnancy checking is a valuable tool for cow-calf producers to optimize their herd performance and profitability. It can help them identify and eliminate open cows that are not contributing to the production goals. It can also help them monitor and improve the reproductive efficiency of their herd.
