Seeding rates for crops are fairly well established in most countries, but when the quantities fed to animals have to be estimated, many aspects must be considered.
Low quality and quantity feeding has been associated with high calf losses in cow dairy herds (Ombura et al. 2007).
Type of concentrates and quantity fed, number of meals per day, silage feeding, other roughages, minerals.
For adequate passive transfer of immunoglobulins (Ig) not only time, but also Ig quantity fed to the calf plays an important role.
These variables were e.g. herd characteristics (presence of other farm animals than cattle on farm), colostrum management (time of first colostrum feeding, quantity of colostrum fed, testing for colostrum quality), calf housing (in- vs outdoor housing, hygienic measures), and feeding (milk quantity fed, access to water, hay and concentrates).
We are growing grain in sufficient quantities to feed a population of seven hundred million souls".
Cows spent similar amounts of time eating and consumed similar quantities of feed in all four tie stalls.
Focused on highly energy efficient water desalination, this project concentrated on the development of a novel approach to Membrane Distillation (MD) capable of handling different quantities of feed waters and high salinity levels.
She organized a phenomenal lobster bake on an island in the Penobscot Bay which featured clams, mussels, lobster, potatoes and corn in quantities to feed 60 people; there were 30 present.
These techniques, collectively known as 'micro-biochemical engineering', require only minimal quantities of feed materials and other resources, thus enabling initial design work to be carried out during early process development.
