Campylobacter; Salmonella Typhimurium; air; monitoring; research; viruses
Abstract:
... The AeroCollect is a new air sampling tool that can capture both bacteria and virus from the air inside poultry houses. Each sample provides enough material for several analyses and hence offers the possibility for identification of different zoonotic and/or bird pathogenic microorganisms in a single sample. In the present study, the performance of the AeroCollect technology was compared to that o ...

Abstract:
... Modern broiler diets may contain excess levels of leucine due to the increased level of this amino acid in cereal grains. Excessive levels of leucine have previously been shown to negatively influence broiler performance due to branched-chain amino acid antagonism. Therefore, 2 leucine titrations were conducted in male and female Cobb 500 broilers. Low and high leucine diets were formulated to con ...

Abstract:
... Distillers dried grain with solubles (DDGS) has been associated with a reduction in pellet production efficiency and quality in animal diets, whereas some minerals may improve pellet efficiency by scouring the surface of the pelleting die holes, reducing friction. The objective of this study was to understand the relationship between DDGS and a dacitic tuff breccia (DTB) based on pellet production ...
