Microscopic speed limits that constrain the motion of matter, energy, and information abound in physics, from "ultimate" limit set by light to Lieb-Robinson quantum spin systems. In addition these state-independent limits, systems can also be governed emergent state-dependent indicating slow dynamics arising, for example, low-energy quasiparticles. Here we describe a different kind limit: situa...

this study was conducted to evaluate production response of early lactating cows to rumen protected fats. twelve (nine multiparous and three primiparous) holstein cows (26±4 d in milk) were empolyed in a replicated 3×3 latin square design of 21-d periods. each period consisted of 14 days of adaptation and 7 days of sampling. cows received diets containing either one of two types of protected fa...
