Antibiotic Therapy in Mastitis Control for Lactating and Dry Cows
(B 1516)
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.
Caring for the Older Horse: Common Problems and Solutions
(B 1368)
Horses have relatively long life spans compared to other livestock and companion animals, often living into their late 20s and early 30s. Many horses have productive careers into their 20s. In fact, in many disciplines, horses do not peak until their teenage years. Good nutrition, maintenance and veterinary care allow horses to lead longer and more productive lives. However, as horses age, their needs change and additional care may be required to keep them as healthy as possible. This publication addresses changes in the aging horse's body that impact its requirements, possible ways to meet these requirements, and solutions to problems that may occur.

Bit selection is a critical area of consideration for riders of all disciplines and levels. Bit selection is often regulated by various breed and/or horse show associations. For many horse enthusiasts, lack of knowledge about bit types and functions, as well as common misconceptions held in the horse industry, can make choosing an appropriate bit a difficult process.
