A Mississippi-based Agricultural Research Service (ARS) researcher has learned that using poultry litter as fertilizer can help cotton growers in the Southeast maximize profits.

Poultry litter (chicken manure, spilled feed, excess feathers, and other poultry-house materials) contains nitrogen and phosphorus—both important crop nutrients. Applying poultry litter to the soil also recycles some of the tons of litter generated annually by poultry operations throughout the United States, says Haile Tewolde, an ARS agronomist at Mississippi State.

Water hardness can influence the development of columnaris disease in catfish, according to a study by U.S. Department of Agriculture (USDA) scientists.

Agricultural Research Service (ARS) scientists found a difference in disease development in fish exposed to hard and soft water containing the bacterial pathogen Flavobacterium columnare, which causes columnaris disease

Using poultry litter as fertilizer is a welcome trend in many southern states because that is where most of the U.S. broiler chickens are produced. The litter's nitrogen content helps boost crop yields, and also helps reduce farmers' expenses for commercial fertilizers. But a U.S. Department of Agriculture (USDA) agronomist has found that many farmers in Mississippi may be applying litter at the wrong time of year.

Classic Caesar salad, old-fashioned eggnog, some homemade ice cream—and many other popular foods—may contain raw eggs. Now, U.S. Department of Agriculture (USDA)-led research has produced a faster way to pasteurize raw, in-shell eggs without ruining their taste, texture, color or other important qualities.

A number of poultry industry groups are using a less costly method to collect avian influenza virus samples, thanks to U.S. Department of Agriculture (USDA) scientists.

 

Avian influenza is a foreign disease that infects poultry and other bird species. Viruses identified as highly pathogenic cause severe disease, killing more than 90 percent of infected birds. Low pathogenic viruses are not as severe, but can cause sickness in birds as well as financial losses
