2024 Dairy Outlook
1. The outlook for 2024 is an improvement over 2023 as feed costs should decline and milk prices remain at similar levels in 2024.
2. Risks remain as improved margins may spur a strong production response and demand growth is uncertain both domestically and overseas.|

Freeze Branding Cattle
To improve efficiency, cattle producers should place a high priority on identifying individual cattle and maintaining accurate records. One type of permanent identification is branding.

Feeder cattle buyers, marketers, and producers are able to communicate the potential growth and carcass merit potential of individual and grouped calves using the USDA Feeder Cattle Grading Standards. Producers that are aware of these standards and their use in predicting carcass value are better suited to making breeding and management decisions to improve the value of future calf crops.

Antibiotic therapy continues to play an important role in the control of mastitis in dairy cows. Lactational therapy is effective against Streptococcus agalactiae but less successful against infections caused by Staphylococcus aureus and other causes of mastitis. As a result, alternative treatment strategies have been developed, including a combination of both intramammary infusion and the parenteral administration (injection) of antibiotics to successfully cure quarters infected with S. aureus. Likewise, extended therapy, which involves prolonged drug administration, has improved cure rates against this organism. Nonantibiotic approaches to treatment have included oxytocin injections, but relapse rates after this form of therapy can be unacceptably high. Dry or nonlactating cow therapy is almost always more successful than lactational therapy because cure rates are higher and new cases of mastitis are prevented. To reduce antibiotic usage, selective dry cow therapy is becoming popular, and teat seals are appealing because they prevent new infections without having to rely on antibiotics.

According to the National Mastitis Council, the recommended milking procedure for dairy animals is 1) provide low-stress environment, 2) check foremilk and udder for mastitis, 3) wash or predip teats with an effective disinfectant, 4) completely dry teats with a single-use towel, 5) attach milking unit within 120 sec of teat stimulation, 6) adjust milking units as necessary, 7) shut off vacuum for removing the unit, and 8) dip teats with a postdip disinfectant. One of the most critical steps in this recommended routine is checking foremilk to not only ensure there are no signs of mastitis and to maintain milk quality, but also to effectively stimulate the teats in preparation for milk collection. Thus, stripping the first three to five streams of milk (foremilk), during the premilking routine serves three important purposes including: teat stimulation which can result in optimal milk release, enhanced milk quality by removing the highest bacterial and somatic cell count milk, and identification of mastitis to allow rapid, well-informed decisions regarding further evaluation, milk culturing, and/or antibiotic therapy. This publication will discuss the purposes of forestripping for dairy animals to serve as an educational resource when creating and evaluating best milking practices.

The purpose of this publication is to serve as an educational
reference and resource to those who are interested
in animal feeding and nutrition. Our primary objective
is to list the common terms used when discussing animal feeding. This listing will also be helpful when reading articles on animal feeding and nutrition, feed analysis reports or tags associated with feeds sold in the market.|

Cattle producers commonly evaluate reproductive performance by determining how many cows became pregnant during the breeding season. Although pregnancy rates are important, when the females become pregnant within the breeding season is a major component of cow-calf profitability. Cows that become pregnant early in the breeding season calve earlier in the calving season. Consequently, they have more time to recover before the next breeding season, which increases their chances of becoming pregnant and staying longer in the herd. Estrus synchronization programs have the ability of inducing estrus and can be combined with natural service to increase the percentage of cows and heifers that become pregnant early in the season. This publication describe different synchronization protocols that can be incorporated by cow-calf producers utilizing only natural service.

Determining an equitable price for purchased forages is a necessary but often uncomfortable topic of discussion for feed growers and purchasers. Usually this discussion is in the context of corn silage; however, the same principles can be used in any discussion involving hay, baleage or grains. In order for an input market to be efficient, the price agreed upon by both buyers and sellers should adequately compensate the producer while still allowing the purchaser the opportunity to economically use the input.
