Clockwatchers: Cagle's says the time is up for cocccidiosis and gangrenous dermatitisNever mind days to market. At Cagle's, Inc., where most broilers are grown to only 3.75 to 4.30 pounds, they'd prefer to measure a bird's life in hours.

Updated strategy improves coccidiosis control and yields added perks for Wayne FarmsA new coccidiosis-control strategy that incorporates vaccination has improved disease control and yielded additional, unexpected benefits for a major US producer.
Proper nutrition the first 15 days of life helps ward off enteritisEnteritis in broilers is most likely to strike from 15 to 30 days of life but can be warded off with good nutrition the first 2 weeks after hatch, said poultry nutrition specialist and consultant Dr. José Barragan, of Spain.
Multiple factors can trigger necrotic enteritis developmentControl of necrotic enteritis requires attention to multiple factors that can trigger the disease, ranging from coccidiosis to the amount of protein in feed, said Dr. Aris Malo, global technical manager, Intervet/Schering-Plough Animal Health.
Consider house conditions, management to get best results with coccidiosis controlGood coccidiosis control and consistent flock performance can be achieved flock after flock, but house conditions and management need to be considered to get the best results, said Dr. Linnea Newman, a consulting veterinarian for Intervet/Schering-Plough Animal Health.
Special Report
Late coccidiosis challenge has 'profound' impact on profitsA coccidiosis challenge late in the production cycle has a profound, negative effect on energy utilization, flock performance and profitability - even when coccidial gut lesions are minor, indicates expansive research by a US nutritionist.
Field experience shows perils of late coccidiosis challengeReal-world experience is corroborating research indicating that a coccidiosis challenge late during the production cycle takes a far more serious toll on broilers and the producer's wallet than an early coccidiosis challenge.
Opinion
�More than 1 billion served�Coccivac-B hit a milestone in 2009 and, for that matter, so did the US poultry industry. For the first time in history, US poultry farms used more than 1 billion doses of the coccidiosis vaccine within a year. Based on USDA figures indicating that over 7 billion broiler chicks have been placed so far in 2009, we estimate that 13% of all US broilers were vaccinated this year with Coccivac-B - nearly double the number vaccinated in 2008.
Real-world resultsVirtually everyone reading this publication is going to be someone who appreciates the importance of research.

Research Watch
'Bio-antibiotics' improve feed conversionUsing green algae, Italian scientists say
they've developed a new strain of antibiotics
that can be used as a growth promoter
without the detrimental effects of products
that are currently banned in some countries.
Caution urged when feeding DDGS, canola to broilersFeeding distillers' dried grains plus solubles
or canola meal could impair performance
and carcass yield, investigators cautioned
at the International Poultry Scientific Forum
in Atlanta.
Vaccination more effective than anticoccidial drugsVaccination is a more effective way to control coccidiosis than drugs and may become less expensive in the future by making use of cross-protection between some Eimeria species, Herman Peek of the University of Utrecht, the Netherlands, says in his doctoral thesis.
