The recovery, R, was determined as a function of time (R *calculated via the relative weight concentrate to feed "yield"), and the k was calculated according to Eq. (2).
The conversion for any given feed was calculated as (feed converted)/(feed fed), while the yield was based on a carbon equivalency, so for all feeds the yield = (carbon in product molecule)/(carbon fed).
When small amounts of N2O (300 ppm, 1000 ppm) were added to the feed, yield and selectivity to H2 and CO increased.
This evolution is due to improvements in CGE modelling such as modifications to the modelling of animal feed, yield responses to price increases, and representation of growth in both supply and demand [ 24].
Larval feeding causes yield loss primarily by pulp consumption and inducing premature fruit dropping.
Today, cows in New Zealand cost less to feed and yield more milk solids, making them more profitable.
They don't need as much space as livestock, emit less greenhouse gases, and have a sky-high feed conversion rate: a single kilo of feed yields 12 times more edible cricket protein than beef protein.

Unlike daytime feeding, nighttime feeding yielded rhythms similar to those generated during ad libitum feeding [ 198].
On d 25, 3 kg of corn grain DM was placed in the rumen 1 h before the morning feeding, and yields of milk and milk components were measured after the challenge.
