A negative MYFG indicates there is insufficient intakes from grazing grass to support maintenance requirements or any additional litres of milk. (nwfagriculture.co.uk)
That equates to a loss of over 3.5 litres of milk, because they haven't analysed their forage to understand their energy base. (overthecounter.news)
However, this amount of milk is about half of what calves would typically drink (around 10 litres of milk over 8-12 feeds per day) in the first month of life if a calf were able to suckle from its dam. (rspca.org.au)

In early lactation, she's wired to make more milk. (liquidfeeds.com)

At this time, DMI generally decreases sharply, limiting nutrient intake. (biomin.net)
Restricted nutrient intake coincides with when foetus development demands are at their highest, placing an additional strain on available glucose. (biomin.net)
A NEB state induces the cow to mobilise body reserves to compensate for the lack of nutrient intake, predisposing the cow to an inflammatory catabolic condition. (biomin.net)

For example, after an overnight fast, 2-6% of energy comes from ketones and this increases to 30-40% after a 3-day fast. (wikipedia.org)
The model predicts the substitution effect on forage intake of increasing rates of concentrate supplementation, the temporal pattern of rumen pH fluctuation with multiple concentrate feedings per day, and increase in dry matter intake when concentrate meals and amount increases. (uoguelph.ca)

With restricted energy consumption, wool growth slows, fiber diameter is reduced, and weak spots (breaks) develop in the wool fiber. (premier1supplies.com)
Fiber, an untapped energy source? (lallemandanimalnutrition.com)
Ruminants, on the other hand, have the unique ability to release the energy from part of the fiber structure thanks to the fermentative activity of the rumen. (lallemandanimalnutrition.com)
Better understanding of how fiber is degraded in the rumen helps identify the levers that can help reach this goal and make sure fiber is no longer an untapped energy source. (lallemandanimalnutrition.com)
Fiber is slowly degraded in the rumen due to its physical structure and the lignin cross-linking that holds the fiber intact. (lallemandanimalnutrition.com)
