2015 Georgia Corn Performance Tests
In this research report, the results of the 2015 corn performance trials are presented. Short-season and mid-season hybrids were planted at Tifton, Plains, and Midville in the Coastal Plain region, at Griffin in the Piedmont region, at Calhoun in the Limestone Valley region, and at Blairsville in the Mountain region. Hybrids used for silage were evaluated at Tifton, Griffin, Calhoun, and Blairsville.

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.

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.

Results of the 2014-2015 performance tests of small grains grown for grain and forage are printed in this research report. Grain evaluation studies were conducted at five locations in Georgia, including Tifton, Plains, and Midville in the Coastal Plain region; Griffin in the Piedmont region; and Calhounin the Limestone Valley region. Small grain forage evaluation tests were conducted at four locations in Georgia, which included Tifton and Plains in the Coastal Plain region, Griffin in the Piedmont region and Calhoun in the Limestone Valley region, and at Marianna, Florida.
