Drought does not develop overnight but progressively over time. Proper management during a drought period can make or break a producer’s ability to stay in the cattle business. One main concern during a drought period is feeding and nutrition of the cow herd. Several problems could arise due to drought conditions. A good producer should stay alert for warning signs and avoid potentially damaging situations.

The number of calves sold is a major source of income from a cow/calf operation. A high percent calf crop increases profit. Reproductive efficiency is the first factor to consider in a breeding program. A beef cow must conceive in the first 40 to 60 days of the breeding season, have a live calf unassisted, breed back to calve every 12 months, and raise a calf that is heavy enough to be profitable. To accomplish this, she must be managed correctly.

Adjust rations for the dry matter (DM) content of each feed, especially when wet feeds, such as silage, are fed. Small changes in the DM content will change the nutrient profile of the ration. The potential results of not monitoring the DM content of wet feeds and adjusting rations accordingly are a combination of problems including decreased animal performance and feed efficiency and increased health problems and feed cost.

Research has demonstrated that proper dry-off methods are vital in promoting udder health during the nonlactating period and at calving. For high producing cows, it may be necessary to decrease dietary energy over the last 1-2 weeks of lactation by increasing fiber and eliminating grain. Abrupt cessation of milking is probably as good as intermittent milking with a diet change for low and medium producing cows; however, intermittent milking is recommended for high producing cows to decrease milk yield and minimize leakage at dry-off, which could lead to mastitis. First lactation cows should be given a 50- to 60-day dry period, but multiparous animals fare well with a 35- to 45-day dry period. Selective dry cow therapy with non lactating cow antibiotics plus teat seal is as effective as blanket dry cow therapy with non lactating cow antibiotics plus teat seal for cows with SCC less than 200,000/ml. However, blanket dry therapy with both products is recommended for cows that dry off with greater than 200,000/ml. It is important to follow recommended infusion techniques to preserve the protective components of teat canal keratin and the sphincter muscle. And lastly, use of coliform vaccines will enhance immunity over the dry period and reduce clinical coliform mastitis in early lactation. This publication address these topics in more detail in order to help producers prevent mastitis in their dairy herds.

Prevalence of mastitis in dairy goats ranges between 5% and 30%, with Staphylococcus spp., otherwise known as the coagulase-negative staphylococci, identified as the most frequent cause of infection. These staphylococci produce persistent subclinical mastitis with markedly elevated somatic cell counts (SCC), which may lead to clinical symptoms.
Prevention is the key to controlling staphylococcal mastitis in dairy goats, as once this disease becomes established, chronic inflammation of mammary tissues and elevated SCC will follow, resulting in reduced milk yield and quality. This publication discusses proper husbandry practices and sanitation methods that can be implemented by producers. The results of two vaccine trials as a potential means to control mastitis in ruminants are also presented and discussed.
Vaccination should only be included as part of the whole herd approach to mastitis control. Any vaccination program must be carried out in conjunction with other proper management practices.

Proper fertilization and liming help maximize fish production in ponds. This resource describes how to effectively fertilize and apply lime to a pond for optimum fish production.

Certain algae can cause serious problems when they become very abundant in drought, hot weather, unusual rainfall patterns, or after nutrient accumulation in pond water. Fortunately, most ponds do not experience toxin problems or dense algal blooms. Watching for the warning signs that lead to toxic algal bloom development is the best way to prevent toxin problems.
This publication describes how to effectively monitor for potential toxic conditions, control algae, and improve water quality in ponds.

Beef Management Calendar
This calendar contains a monthly listing of the common management practices needed for commercial beef herd production in Georgia. Some are recommended at a certain time of the year and others are recommended when calves are a certain age or at a certain point in their reproductive cycle.

Water is a critical nutrient that receives little attention until a problem arises. Not only should producers make an effort to provide water in adequate quantity, they should also know what is in the water to be used in evaporative cooling systems and consumed by the birds.
