In pig farming, odour measurement and reduction are necessary for a cleaner environment, lower health risks to humans, and higher quality of pig production. There have been many studies on the modelling of pork farm odour by analysing the chemical co

The number of non-farming rural residents surrounding pork farm operations has increased greatly in many pork-producing nations. These non-farming rural residents consider pork farm odour emissions to be a serious health threat. This has led to signi

Pork farm odour has become an increasingly important problem for the pork industry because non-farming rural residents object to the odours coming from pig facilities and insist that it disrupts enjoyment of their properties. The pork industry has th

To address the problem of manure-based environmental pollution in the pork industry, we have developed the phytase transgenic pig. The saliva of these pigs contains the enzyme phytase, which allows the pigs to digest the phosphorus in phytate, the mo

Circadian levels of melatonin were determined in the hepatic portal vein, cranial vena cava, and the lower aorta of ten juvenile pigs. Blood was sampled every hour for a total of 24 hr via temporary cannulas introduced into blood vessels under anesth
