Methods of Yoking Bullocks
both the euglobulin and pseudoglobulin I farctions
are less in the protein-deficient than in the control
group. Since globulins are associated with the
maintenance of body integrity, it may be that the
decreased amounts of these immunologically active
fractions in protein deficiency render the animals
more susceptible to infection.
SUMMARY
Observations on the morphological and chemical
constituents of the blood of normal cattle and
of those fed on a protein-deficient diet are presented.
It has been found that the red cells, white cells,
cell volume, sugar, haemoglobin, iron, total choleste-
rol, calcium, inorganic phosphorus, magnesium, non-
protein nitrogen and the protein fractions are
decreased in protein-deficient animals. As the
globulins are especially associated with the integrity
of the body cells, it may be that the decreased
amounts of these immunologically active fractions
in protein-deficient animals render them more suscept-
ible to infection.

REPORT ON A DETAILED STUDY OF METHODS OF YOKING BULLOCKS
FOR AGRICULTURAL WORK PRESENTED TO THE IMPERIAL
COUNCIL OF AGRICULTURAL RESEARCH
By M. VAUGH, Agricultural Engineer, Allahabad Agricultural Institute
(Received for publication on 28 September 1944)
(With two text-figures).
THIS is a report of a study which is part of a larger
programme of research being carried out at the
Allahabad Agricultural Institute on the methods of
yoking bullocks for agricultural work and on the
effect of body conformation on draft ability of work
animals. This report will deal with the study of
yoking methods, yokes and harness.
The main object of the whole scheme was to secure
information on the effect body conformation has on
the draft ability of work cattle. This information,
especially if a positive correlation were found, should
provide a basis for selecting breeding animals. If
readily measured or recognised body measurements
can be determined which are consistently associated
with high draft ability, they should be a valuable
guide to the animal breeder in selecting breeding
stock. We wished to determine how far any such
measurements associated with draft ability coincided
with body measurements or proportions known to be
consistent with milk yielding ability. We particularly
