<p>Researcher from University of Oxford recently developed new camera based techniques which determines the “Optical flow” in chickens, to The technique could help in detection of which flock is infected only when birds are days old. The concern research can great support in prevention of food poisoning mostly caused by campylobacter infections.</p><p>This study is published in the Journal proceedings of the royal society B. &#039;Humans consume nearly 60 billion chickens a year -- more than any other animal. At the same time, there is a worldwide epidemic of human gastro enteric disease caused by Campylobacter. It is estimated that up to four-fifths of this disease originates from contaminated chicken meat, Said Dr. Dr Frances Colles, from Department of Zoology, University of oxford and lead author of this research.<br /><br /><img src="http://www.microbiozindia.com/images/JHU.png" alt="" /></p><p>According to researcher,</p><p>&#039;Optical flow works by detecting the patterns formed by changes in brightness in moving images, both temporally and spatially. It is computationally simple and does not require tagging or marking individual animals, making it ideal for long-term continuous monitoring of large groups of similar animals such as egg-laying hens and broiler chickens, where optical flow is predictive of key welfare measures such as mortality rate.</p>rn&#039;rn<p>Note: For more information go through original story source.</p><p>Story Source : University of Oxford</p><p>Journal References</p><p>Frances M.
