Do you remember the story about "Goldilocks and the Three Bears." The story goes that Goldilocks visits the three bears when they are not at home. She finds three bowls of porridge on the table and she tries them. She finds one too hot, one too cold and one just right and she eats the whole bowl. The story goes on but I think we can apply this principal to cows in the beef herd as well.

This is a good time to be checking on the body condition of the cow herd. We need to look for some that may be too thin, some that may be too fat and some that are just right. Hopefully most of them will be just right.

In order to manage a beef cow-calf operation in the most cost-efficient way, producers must be aware of the body condition of their herd. Research indicates that the body condition of beef cows is related to many critical aspects of production such as conception rate, days to estrus, calving interval, and milk production. When cows are extremely thin they are not only reproductively inefficient, but they are more susceptible to health problems. On the other hand, cows that are over-conditioned are the most costly to maintain. Over-conditioned two-year-olds may encounter calving difficulty due to the excessive fat in the pelvic area.

Body condition scoring (BCS) is a useful management tool for distinguishing differences in nutritional needs of beef cows in the herd. This system uses a numeric score to estimate body energy reserves in the cow. Research indicates that there is a strong link between the body condition of a cow and her reproductive performance. The percentage of open cows, calving interval, and calf vigor at birth are all closely related to the body condition of cows both at calving and during the breeding season.

All these factors play an important role in the economics of a beef cow-calf operation and help determine the percentage of viable calves each year. Monitoring body condition using the BCS system is an important managerial tool for assessing production efficiency. The mature cow should be a BCS of 5 at calving and heifer should be a BCS of 6. Research has shown the females with a BCS lower than 5 will be much slower to breed back.

Take a hard look at the "3" cows. Is it going to be economical to bring them back to the point where they should be? Marketing these animals may be the best option. Just remember that it takes an 80 to 100 pound increase in weight to move up just one body condition score, and it will require a lot of feed.

As the feeding program is developed, remember that energy is the most important nutrient. Adequate protein is required, but energy is the nutrient that will add weight. Be sure to monitor the BCS as the feeding program progresses.

The goal is to get a good calf on the ground each year. Beef producers need to know when the cow is not too fat or not too thin but just right.

Bull Test Station Open House …. Thursday, December 5, 2019. This event offers visitors a chance to view 105 bulls that will be featured in this winter's Bull Test Sale. There is no cost to attend, and lunch will be provided. The open house begins at 9:30 a.m. CST with an educational program covering the latest technologies in beef cattle genomics and an overview of research conducted at the Bull Test Station. The sessions will also include discussions on bull selection and how to choose a bull that will best fit your operation.
