Can you recommend animal husbandry sites for comparing feeding and housing practices on commercial livestock farms?

Yes—here are some useful animal husbandry resources for comparing feeding and housing practices on commercial livestock farms. I’ve grouped them by type so you can choose depending on whether you want research-based, industry, or regulatory comparisons.

Good general resources

• FAO (Food and Agriculture Organization)
  Good global overviews on livestock systems, feeding strategies, housing, welfare, and management.
  https://www.fao.org/livestock/en/

• Merck Veterinary Manual
  Practical reference for animal care, housing, nutrition, and production systems across species.
  https://www.merckvetmanual.com/

• CABI / CABI Digital Library
  Strong for applied animal science and husbandry practices, especially in farm management contexts.

Livestock-specific and comparative sources

Cattle

• University extension sites such as:
  • Penn State Extension
  • University of Wisconsin Extension
  • UC ANR (University of California Agriculture and Natural Resources)
  • Texas A&M AgriLife Extension
    These often have side-by-side material on housing systems, nutrition, stocking density, barn design, grazing vs. confinement, etc.

Dairy and beef production

• The Dairy Site
  Useful for practical dairy feeding, housing, and welfare management comparisons.
  https://www.thedairysite.com/

• The Cattle Site
  Covers beef and dairy management topics.

Poultry

• The Poultry Site
  Strong for comparing cage, cage-free, aviary, broiler housing, feed conversion, stocking density, and welfare.
  https://www.thepoultrysite.com/

Swine

• The Pig Site
  Good for sow housing, farrowing systems, group housing, feeding methods, and production comparisons.

Sheep and goats

• Small Ruminant Resources from university extension programs
  Often the best source for housing and feeding comparisons in commercial or semi-commercial systems.

Research and review sources

• Google Scholar
  Best for finding review articles comparing feeding/housing systems.
  https://scholar.google.com/

• PubMed
  Helpful if you want animal welfare, veterinary, or physiology-focused literature.
  https://pubmed.ncbi.nlm.nih.gov/

• ScienceDirect / Springer / Wiley Online Library
  Good for peer-reviewed review papers and system comparisons.

Animal welfare and standards sources

• WOAH (World Organisation for Animal Health)
  Welfare standards and husbandry recommendations.
  https://www.woah.org/

• RSPCA Assured / Certified humane standards
  Useful for comparing housing requirements and feeding/welfare expectations in certified systems.

• National animal welfare standards or farm assurance schemes
  Often provide very clear housing/feeding benchmarks for commercial farms.

If you want direct farm practice comparisons

Look for:

• extension fact sheets
• farm assurance standards
• species-specific production handbooks
• peer-reviewed review articles
• industry benchmark reports

If you want, I can also give you:

1. a short list of the best sites by species (cattle, pigs, poultry, etc.), or
2. a comparison table of feeding and housing practices across commercial livestock sectors.
