Everything else — rumination, lameness, oestrus, welfare — is inference, and inference has error bars.https://en.bioecon.ru/docs/agri-food/livestock-aqua/aquaculture-fish-farming/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/aquaculture-fish-farming/A fish does not pay to keep itself warm and does not carry its own weight. Both facts, and the gas chemistry of the water it sits in, set what a farm can do.https://en.bioecon.ru/docs/agri-food/livestock-aqua/aquaculture-microbiome/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/aquaculture-microbiome/A fish lives inside its own transmission route. The water is the reservoir, which is what makes the tank community manageable and the probiotic dose transient.https://en.bioecon.ru/docs/agri-food/livestock-aqua/industrial-single-cell-protein-for-feed/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/industrial-single-cell-protein-for-feed/A microbe that grows fast is a microbe full of ribosomes, and ribosomes are RNA. That single fact sets the inclusion ceiling.https://en.bioecon.ru/docs/agri-food/livestock-aqua/livestock-gene-editing-precision-breeding/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/livestock-gene-editing-precision-breeding/Almost every livestock edit that has worked is a broken gene, not a better one. That is a statement about genetic architecture, not about ambition.https://en.bioecon.ru/docs/agri-food/livestock-aqua/methane-reduction-ruminants/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/methane-reduction-ruminants/Methane is how the rumen disposes of hydrogen. Any inhibitor must give that hydrogen somewhere else to go, or fermentation itself slows down.https://en.bioecon.ru/docs/agri-food/livestock-aqua/microbiome-phage-preparations-animals/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/microbiome-phage-preparations-animals/A phage’s specificity is why it spares the gut community — and why a cocktail matched to this year’s strains stops matching.https://en.bioecon.ru/docs/agri-food/livestock-aqua/sperm-sexing-reproductive-biotech-livestock/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/sperm-sexing-reproductive-biotech-livestock/The X-bearing bovine sperm cell carries about 3.8% more DNA than the Y-bearing one. Everything in this field is built on measuring that difference one cell at a time.https://en.bioecon.ru/docs/agri-food/livestock-aqua/trace-mineral-feed-additives/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/trace-mineral-feed-additives/How much zinc is in the feed is the easy question. How much of it reaches the animal, and what it displaces on the way, is the whole subject.https://en.bioecon.ru/docs/agri-food/livestock-aqua/veterinary-biotech-mrna-drugs/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/veterinary-biotech-mrna-drugs/The molecule is the same as in human medicine. The economics, the cold chain and the acceptable cost per animal are not, and that is what decides where it is used.https://en.bioecon.ru/docs/agri-food/livestock-aqua/veterinary-genomics-companion-animal-diagnostics/Mon, 01 Jan 0001 00:00:00 +0000https://en.bioecon.ru/docs/agri-food/livestock-aqua/veterinary-genomics-companion-animal-diagnostics/A variant discovered in one breed is a fact about that breed. Reporting it across all dogs is where most of the field’s false results come from.
