(10) w i j = max s (| C max i s − C max j s | max (C max i s, C max j s ) ) where C max i s = max (C i s (t ) ) The by-production efficiency is defined as the ratio of by-production intake rate to primal carbon resource uptake rate.
The aim of this feeding trial was to analyze the effect of the full substitution of a common concentrate mixture with a by-product concentrate mixture on milk production, feed intake, blood values, and the edible feed conversion ratio (eFCR), defined as human-edible output per human edible input.
Individual milk production, feed intake, and milking frequency were recorded daily, while milk composition and milk FA daily were analyzed weekly.
The objective of this study was to evaluate the effects of dry period length and dietary energy source in early lactation on milk production, feed intake, and energy balance (EB) of dairy cows.
These results indicate that predictions of the new WFM are relatively accurate and precise, with a conclusion that incorporating a plant-animal relationship model into the WFM allows for dynamic predictions of residuals and more realistic simulations of the effect of grazing pressure on herbage production and intake at the farm level without the intervention from the user.
Milk production, feed intake, and digestion remained normal among the 48 milk-producing cows that were given the supplement over 12 weeks.
Because of the steep reduction in the production and intake of industrial trans fatty acids, ruminant fats are now the major source of trans fatty acids in most European countries [9] and will likely become so in the USA [10].
Accordingly, lactate production, glucose intake and sensitivity to glucose deprivation were significantly reduced.
For most chemicals, relative to the uncertainty in published production data, intake uncertainty is small.
In adults, achieving blood levels of 5 to 7 mM/l total KB requires the production or intake of about 150 g per day [ 23].
