The Local Livestock Sale Barn

Advances in livestock genomics: opening the barn door.

Genome research in animals used in agriculture has progressed rapidly in recent years, moving from rudimentary genome maps to trait maps to gene discovery. These advances are the result of animal genome projects following closely in the footsteps of the Human Genome Project, which has opened the door to genome research in farm animals. In return, genome research in livestock species is contribu...

Laboratory-scale investigation of UV treatment of ammonia for livestock and poultry barn exhaust applications.

The feasibility of using deep ultraviolet (UV) treatment for abatement of ammonia (NH(3)) in livestock and poultry barn exhaust air was examined in a series of laboratory-scale experiments. These experiments simulated moving exhaust air through an irradiation chamber with variables of UV wavelength and dose, NH(3) concentrations, humidity, and presence of hydrogen sulfide (H(2)S). Ammonia, init...

Challenges and opportunities in genetic improvement of local livestock breeds

Sufficient genetic variation in livestock populations is necessary both for adaptation to future changes in climate and consumer demand, and for continual genetic improvement of economically important traits. Unfortunately, the current trend is for reduced genetic variation, both within and across breeds. The latter occurs primarily through the loss of small, local breeds. Inferior production i...
