Latest field notes
Field noteRumen · Reading silage fermentationA mold count is not a mycotoxin testViable molds and chemical toxins are different measurements, and patchy contamination challenges both. 
Rumen · Reading the feed reportA number without a unit is not a resultPercent, ppm, mg/kg, Mcal/lb, and Mcal/kg can turn the same digits into very different decisions.
Rumen · The feed composition mapAsh is not a mineral panelAsh measures total inorganic residue; it cannot tell whether calcium, potassium, or soil contamination caused the result.Field noteRumen · Reading fiber fractionsChemical fiber is not effective fiberGrinding can leave the NDF percentage intact while removing much of the particle structure that stimulates chewing. 
Rumen · Reading the feed reportCompare the feed, not the waterAs-fed columns answer loading questions; dry-matter columns answer nutrient-concentration questions.Field noteRumen · Reading proteinCrude protein is only the headlineCP counts nitrogen equivalents; it does not reveal solubility, rumen degradation, heat damage, or absorbable amino-acid supply. Field noteRumen · The feed composition mapDry-matter drift changes the loadWhen silage moisture moves and mixer kilograms stay fixed, nutrient delivery moves even if the written ration does not. Field noteRumen · Reading carbohydrates & energyEnergy on the report is a model outputRoutine NEL and TDN values are usually calculated from chemistry and assumptions, not collected as direct substances from the sample. Field noteRumen · Reading proteinEscape protein still has to digestRUP describes rumen escape, not guaranteed intestinal absorption. Field noteRumen · Reading proteinHeat damage can hide behind CPNitrogen can remain in the sample even after heating makes part of it poorly available to the cow. Field noteRumen · Reading mineralsMineral concentration is not daily supplyThe cow receives grams or milligrams per day, not a percentage printed for one ingredient. Field noteRumen · Reading fiber fractionsNever drop the digestibility clockNDFD30 and NDFD48 are different measurements because the microbes had different amounts of time.
