The tail IL often measured In judging
the COW and should roach to or below
the hooks and carry 4 good switch.
This readers It most useful In brush
ing flies. which appears to bo its chief
purpose.
In Judging the quality and condition
of the muscular tissue Of the body one
shonld remember to take into consid.
eration the size, age, and stage of
lactstion Of the animal. The bone
and muscular tissues in = large COW
are naturally heavier than in q small
one and there is not the apparent re-
nnement and spareness of form in the
large breeds that Is noted in the
smaller ones. Marked coarseness,
however, in any animal is usually
! accompanied by . sluggish disposi-
tion which in dairy COW prevents
her from performing satisfactorily.
Young heifers with first calf usually
carry more flesh than cows of mature
form. All properly fed cows usually
show . higher condition Of flesh de-
velopment toward tho close of their
lactation and prior to freshening than
they do when four or five months ad-
vanced In lactstion.
The Uddsr.-The udder is the milk
secreting organ and its proper devel.
many instances cows of large digestive
capacity and of dairy breeding have
failed in production apparently on ac
, count of poorly developed udders. The
udder consists of two large glands
| each Of which 10 more or less distinct
ly divided to correspond with each O
the four teats and form the quarters
The duct Of each teat enters a small
cavity termed the milk cistern. Th
milk cistern OF each quarter is NOR,
| or less surrounded by lobes Of CLAN,
tissue held in position and closely to
Kether by connecting tissue. Thes,
lobes may be hkened to thick bunche
of grapes since each lobe has severa
| lobules corresponding to the grapes
The lobules are made OF small division
called alveoli which correspond to tn,
seeds Of grapes. These alvsoli ars
constructed Of small cells surrounded
| by q ine network of blood vessels an6
nerves and 1t Is by these cells that the
milk is secreted,
o The best cows have comparatively
large udders with equally developed
quarters extending well forward un
darneath the body and good distance
up behind and between the. thighs
Poor attachment giving a swinging or
pendant type Of uddsr and deficiency
and irrsSufarity III the development Of
the quarters are criticisms to be Of
fered on many cows. Tho quality of
the udder when examined by handling
! should reveal gland tissue of fine,
plastic texture rather than fatty tissue
or . texture that is coarse and hard
The cireulatory system.-This sys
ten determines the activity Of the
COW with respect to all parts Of the
body. Only when in perfect health
and all parts Of the body are actively
perfosming their respective fupctions
can the dairy COW be expected to yield
| . large flow Of milk. When tho COW

viduality IL dali and morbid there 10
an inactivity of all tho glands of the
body resulting In q dry. harsh condi
4 ton of the skin, . staring coat, and q
low production Of milk. The ctrcula-
tory system includes the heart, lungs
arteries and veins since these organs
respectively force, purify and carry
| blood to and from all parts Of the
/ body. When food becomes disested
!, and assimilated the blood must carry
1t to the parts Of the body demanding
it and In the dairy COW the glands of
the udder demand q large share Of the
!, nonrtshment Of the blood for the secre-
ton Of milk. The size and character
Of the mi1k veins. more properly
termed "mammary veins" and tho
milk wells on the underside Of the
body are the best indications Of how
!, much blood passes through the udder.
These veins do not cary milk as some
people believe, but carry 4 large por.
dom Of the blood away from the udder
The blood passes into the udder
through arteries located deep on the
inner side Of the thighs. II one were
