Calving Emergencies in Beef Cattle: Identification and Prevention

Calving difficulty, technically called dystocia, is a major cause of death loss in cow-calf herds. CHAPA (Cow-calf Health and Productivity Audit) studies indicate that dystocia is responsible for 33 percent of all calf losses and 15.4 percent of beef cattle breeding losses.

Current Strategies in Parasite Control in Virginia Beef Cattle

Many advances have been made in the field of livestock parasite control over the past few years. Because parasites decrease production, usually through decreased weight gain, advances in the control of parasites can have a direct economic impact on beef cattle operations.

Estrus Synchronization for Heifers

Developing replacement heifers is the most expensive enterprise in the cow-calf operation. You can increase returns to heifer development if the heifers calve at 24 months of age and calve early in the calving season.

Feeder and Stocker Health and Management Practices

Disease represents a major problem in most feeder and stocker settings. In some instances, outbreaks of disease can result in as much as a 30% death loss. In addition, treatment costs, feed efficiency losses, and the expenditures and labor necessary for treatment, as well as the necessity of culling animals which fail to respond to treatment, make disease loss substantial in many situations.

GnRH Based Estrus Synchronization Systems for Beef Cows

New systems of synchronizing estrus (heat) in cows for artificial insemination (AI) have been developed using commercially available Gonadotropin Releasing Hormone (GnRH). These systems allow producers to artificially inseminate cows with little or no heat detection. For the first time, producers have a reliable system that results in acceptable pregnancy rates to timed AI.

Goat-Herd Health Calendar

The goal of any goat-herd health program should be to increase efficiency and productivity. Herd health programs should include general husbandry, nutrition, and parasite and vaccination programs. Your emphasis should be on disease prevention rather than treatment. There are three major approaches for disease control:

  1. Keep resistance high.
  2. Avoid exposure.
  3. Recognize and address diseases early.

Mycoplasma in Beef Cattle

Mycoplasma is a tiny bacterium that has a long history of causing disease in the cattle industry. Beginning in the early 2000s, it has emerged as an important entity in Virginia.

Mycoplasma in Dairy Cattle

Mycoplasma is a tiny bacterium that can cause mastitis, metritis, pneumonia, drooped ears, and lameness in dairy cattle. While this bacterium has existed for more than 100 years, the current disease was first recognized in the 1960s and 1970s, and has only recently become a problem in Virginia. There has been a steady rise in the frequency and severity of disease associated with Mycoplasma in the last ten years. Mycoplasma is a highly contagious disease that can have devastating economic effects on a dairy farm due to decreased milk production, additional veterinary costs, culling of cows, calf loss, and treatment cost. All dairy animals can be infected, including calves, heifers, dry cows and lactating cows.

Pinkeye in Beef Cattle

Pinkeye, also known as infectious bovine keratoconjunctivitis (IBK), is one of the most common diseases of beef cattle in Virginia. It is a highly contagious disease, causing inflammation of the cornea (the clear outer layer) and conjunctiva (the pink membrane lining the eyelids) of the eye.
