Swine Respiratory Health May Shed Light on Human Lung Disease

North Carolina Agricultural and Technical State University (N.C. A&T) animal sciences researchers are studying the respiratory health of swine raised indoors and outdoors.

The D-A-R-T Way to Handle Cattle

One way to diagnose cattle is to use the D-A-R-T system. The letter “D” stands for depressed; the letter “A” stands for appetite; the letter “R” stands for respiration, and the letter “T” stands for temperature.

Dairy Cows’ Carbon Footprints from Barn to Field

A University of Wisconsin–Madison researcher began using a specialized device to measure the methane being exhaled or belched by a group of Holsteins and Jerseys. It was the first step in an ongoing study by dairy scientists, engineers, and agronomists to see how a cow’s breed and forage consumption affect the greenhouse gases generated by her gut and her manure.

Study Provides Evidence of Parental Infanticide in a Grassland Bird Species

University of Illinois (UI) researchers are monitoring dickcissel nests as part of a larger ongoing study examining the effects of fire, grazing, and herbicide application on the grassland-dwelling species. In extremely rare cases, parents have been observed removing their own chicks from their nests. The new study documents the mysterious and fatal behavior in dickcissels for the first time.

OSU Study Clocks Low Time for Cattle Stream Use

Researchers at Oregon State University using precise tracking technology discovered that cattle spend less time in streams than prior believed.

Fluorescent Fish Making a Mark

Researchers at the University of Arkansas Pine Bluff (UAPB) tested the application of calcein, a fluorescent dye that produces visible external marks on fish, as a potential substitute for traditional chemicals.

Mucosal Environment of Older Pigs Helps Newborn Piglets with Intestinal Injury Recover

Researchers from North Carolina State University (NC State) have found that the intestinal mucosal environment of juvenile pigs can stimulate repair of intestinal injuries in newborn piglets. The findings have implications both for understanding why newborns of many species – including humans – are unable to repair these injuries on their own, as well as for potential future treatments.

Successful Transition Cow Program Could Save Iowa Farmers $1.2 Million

Dairy producers throughout Iowa were able to re-evaluate best management practices for their transition cow program. Project Director Jennifer Bentley notes that while transition cow management encompasses only 20-30 percent of a herd, it ultimately influences the milk production and health of 100 percent of the cows.

Researchers Investigate Influence of Heat Stress on Pig Fetal Development

Researchers at Iowa State University are investigating how heat stress can influence a pig’s fetal development and postnatal life, including the ability to develop and grow. NIFA originally published this impact in the NIFA 2015 Annual Report.

Researchers are Working to Improve Feed Efficiency in Beef Cattle

Animal science researchers at the University of Missouri are working to improve feed efficiency in beef cattle. NIFA originally published this impact in the 2015 Annual Report.
