Netting on trees, Anaesthetic shortages, Turning slurry into bedding

The practice of covering trees with netting to prevent wildlife from taking hold is proving an emotive issue for environmentalists and Alun Beach has been to meet some of the people taking steps to remove it. Simon Doherty from the British Veterinary Association speaks to Anna Hill about the shortage of procaine hydrochloride found in many animal medicines, particularly anaesthetics, and the problems this shortage has caused. Anna also asks Rachel O'Connor, a speaker at a conference on insects as food & feed, about the growth of the insect protein industry and what steps would need to be taken for it to become a feed for livestock. Charles Goadby uses the slurry produced by his cows to create the bedding they need in their cubicles - Ben Jackson's been to meet him for farm waste week.
