A Greener World’s farm standards are developed in collaboration with scientists, veterinarians, researchers and farmers across the globe to maximise practicable, high-welfare farm management.
As well as providing practical advice for farmers, vets and advisers, our Technical Advice Fact Sheets, Information Sheets and Briefing Papers explain the scientific assessment and reasoning behind many of our key farm standards. We hope the information will help those with an interest in the programme to have a greater understanding of our position on key management issues and animal welfare.
Technical Advice Fact Sheets (TAFS)

This technical paper looks at the importance of soil testing in sustainable livestock systems. Key topics include the reasons for soil testing, the benefits of soil testing and best practice for pasture production.
- TAFS 13 – The Prolific Hen
This technical paper examines the welfare concerns about modern prolific laying chicken breeds and considers egg production numbers, health problems arising from high numbers of eggs per cycle and advice on suitable and unsuitable breeds.
- TAFS 14 – Farm Health Plans: A Practical Guide
Introducing a farm health plan–and keeping it up to date–can help prevent health problems in livestock and significantly improve overall farm performance. This technical paper offers advice on the creating and maintaining a dedicated farm health plan.
- TAFS 15 – Record Keeping
This technical paper explains how record keeping can benefit your farm business, explaining what records are required by AGW, what constitutes a ‘record’, and just how easily you can incorporate record keeping into your daily routine.
- TAFS 16 – Nose Ringing Pigs
This technical paper examines the practice of nose ringing pigs. Key topics include understanding the welfare implications of nose ringing and management options as an alternative to nose ringing.
- TAFS 17 – Age of Weaning Lambs
This technical paper examines the impact of different weaning ages on the welfare of ewes and lambs, the importance of good nutrition during lactation, and the impact of weaning age on lamb growth and productivity.
- TAFS 18 – Why Pre-Slaughter Stunning is Important
This technical paper examines the issue of pre-slaughter stunning. Key topics include minimising pain and stress at slaughter, evidence of pain at the bleed cut and the time to loss of consciousness without prior stunning.
- TAFS 19 – Avoiding the Need to Teeth Clip Piglets
This technical paper examines the practice of teeth clipping piglets. Key topics include why teeth clipping is carried out, problems with teeth clipping, and management of the sow and litter to avoid teeth clipping.
- TAFS 20 – Pre-Slaughter Stunning – Why it is Important for Poultry
This technical paper explores the issues of pre-slaughter stunning of poultry. Key topics include minimising pain and stress at slaughter, evidence of pain and the time to loss of consciousness without prior stunning, and what happens when an animal is stunned.
- TAFS 21 – Weaning Age in Beef Cattle
This technical paper examines the impact of early weaning on calf and cow (including scientific evidence of stress and production issues), and the benefits of later weaning for both calf productivity and cow condition.
- TAFS 22 – Faecal Egg Counts
This technical paper discusses faecal sampling to monitor the internal parasite burdens of livestock, explaining what’s involved and how the results can be used, as well as providing links to public and private laboratories that can carry out the tests.
- TAFS 23 – Feed Calculation for Ruminants
This technical paper explains how farmers can calculate how much their animals are eating each day and how much non-forage feed they can provide while maintaining compliance with AGW standards. Includes useful reference tables to aid feed calculations.
- Guidelines for Farms that Host Open Days Hosting farm visits offers the public a real insight into practical farming–and farmers the opportunity to show off their farms, livestock and the high welfare food they produce to interested customers! But as well as being informative and enjoyable, every farm visit should be a safe experience. This information sheet offers basic guidance on key health and safety measures to ensure everyone has a great day out.
- Sheepdogs: Breeding, Feeding, Housing and Welfare Information Sheet: The ‘Border Patrol’ article in Sustainable Farming magazine was based on this piece written by Barbara Sykes, leading author on training border collies and owner of Mainline Border Collie Centre, UK. This information sheet offers guidance on puppy selection, appropriate housing, ensuring a good diet and general welfare, and establishing a strong bond with your dog.
- Dual Production and Sale of Product Policy with the goal of ensuring that non-certified products do not get the marketing benefit of association with certified products and farms.
- Animal Byproducts Statement Statement on AGW’s standards on feeding animal byproducts.
- OP and Non-OP Parasite Treatments Information on prohibited and acceptable external parasite control products for animals within the Animal Welfare Approved by AGW program.
- Comments on Holt white paper on range access for hens
In 2011, Dr. Peter Holt, published an important article in Feedstuffs: The weekly newsletter for agribusiness. Dr. Holt claimed the welfare benefits of free-range poultry systems are primarily based on welfare perception, rather than scientific welfare facts. By examining the limitations of the scientific research upon which he bases his argument, and by presenting a range of alternative research, Dr. Holt’s conclusions are robustly challenged.
- Comments on Glasgow research on antimicrobial resistance
Following the publication of a research paper in the Proceedings of the Royal Society B journal, several agricultural industry websites and magazines used the research to argue that antibiotic resistance does not result from the overuse of antibiotics in animal agriculture. But upon closer examination, AGW subsequently uncovered numerous weaknesses in the analysis used, questioning the controversial conclusions of the research paper.
- Trichinella and Pastured Pigs
Numerous reports and articles claim that eating meat from pastured pigs represents a greater risk of contracting the parasitic disease, trichinellosis. This briefing paper gives details of the disease, its source and transmission, and examines results from the national trichinellosis surveillance system and various research papers. A review of current research concludes that the risk of contracting trichinella from eating pork from well-managed pastured systems is no greater than from indoor pork.
