Broiler Chick and Laying Hen Tolerance to Sodium Hypochlorite in Drinking Water

Susceptibility of drinking water biofilm bacteria to sodium hypochlorite

The Fate of Sulfamethazine in Sodium-Hypochlorite-Treated Drinking Water: Monitoring by LC-MSn-IT-TOF

Pharmaceutical compounds represent a rapidly emerging class of environmental contaminants. Such compounds were recently classified by the U.S. Geological Survey, including several antibiotics. An LC-MS/MS screening method for the top five antibiotics in drinking water was developed and validated using a Shimadzu LC-MS-IT-TOF. The separation was performed using a Waters Acquity UPLC BEH C18 colu...

Effect of sodium hypochlorite on typical biofilms formed in drinking water distribution systems.

Human health and biological safety problems resulting from urban drinking water pipe network biofilms pollution have attracted wide concern. Despite the inclusion of residual chlorine in drinking water distribution systems supplies, the bacterium is a recalcitrant human pathogen capable of forming biofilms on pipe walls and causing health risks. Typical drinking water bacterial biofilms and the...

Effects of Laying Hen Manure Application Rate on Water Quality

Excessive use of animal manure on agricultural lands can impact the quality of surface and groundwater resources. A three–year study (1998–2000) was conducted on nine 0.4–ha plots and on six 2.1–m 2 lysimeters to investigate the effect of two nitrogen (N) application rates from laying hen manure and one N application rate from urea ammonium nitrate (UAN) fertilizer on surface and groundwater qu...

Nonruminant Nutrition: Poultry Nutrition - Breeder and Laying Hen Nutrition and Broiler Environment

1 in southern Japan, Bs was added to all broiler feeds (0 or 3x105 CFU/g), and excreta collected at 2 ages. At 14 d, in the Bs ock Lac increased (P<0.05) and Salmonella were not detected vs 4.97 Log10 CFU/g excreta in the negative control ock. At 49 d, Clostridium perfringens (3.22 vs 2.66 Log10 CFU/g excreta; P<0.05) and Salmonella (4.07 vs 3.31 Log10 CFU/g excreta, P<0.01; 20/20 vs 10/20, P...
