Abstract
In 1810, many years before the nature of the
organic nutrients in food was appreciated, Thaer developed
his "hay values" as measures of relative nutritive value.
Following the recognition of protein, fat and carbohydrate
as the essential organic nutrients, Grouven in 1859 made use
of analyses for these nutrients to formulate the first feeding
standards for farm animals.
Feeding standards are tables showing the amounts
of food and nutrients which should be provided in the rations
of different species for different purposes, such as growth,
fattening and lactation.
In order to combine various feeds into rations that
will meet the requirements of livestock, it is necessary,
first of all, to have definite knowledge concerning the
chemical composition of these feeds.
A large proportion of the barley, oats and wheat
grown in Canada is used for feeding livestock. The evaluation
of these grains, therefore, is a matter of interest to
stockmen, farmers and agrologists generally.
At present government grades for oats, barley and
wheat are used to indicate the quality of these grains as
they enter commerce. During recent years the question has
been raised as to how accurately quality is reflected in the
official grades.
The grades are determined by an examination of
physical factors such as bushel weight, shape, colour, and
seed coat texture. The use of physical factors alone in the
determination of composition or quality undoubtedly has
