SPAYING OF COWS,

comparative ply siology lags in regard to
the needed progress. A few ihings,
/ however, are quite certain, among which
may be stated the great analogy between
the physiological functions Of domestic
animals and the human race. Although
our knowledge in regard to the human
race is further advanced than that in re-
gard TO animals, yet we NAV believe that
great discrepancies have no, been found
in saking our knowledge of any iunc
tons Of the human organization as a
point oil departure. and then making
reference 10 the same functions in animals
Milk flow, OF rather milk. secretion, is q
function subsidiary to reproduction with
every animal in nature. Ii is for the
susten'ion of the yoang, before their
organs of mastica,ion and digestion are
sufficiently malured TO cope with the
coarser diet of the adult. After the
milk secretion organ has been active a

function should be transferred 10 the

The proposition, then, is having given
COW in state Of milk to prevent this
transfer, by the removal of the ovaries
from the animal. One thirg among
those which are certain is, that there can
be no commencement OF reproduction
after the removal of the ovaries; there
can be no intervals Of gong dry any
months in the year; if once dry she must
be dry for life. Another thing is abso

method by which animals are necessarily
operated upon. Ii is sufiicien, here to

the mode of access. /! should be per-
formed during milk flow, and some time
before the anticipated heGt of the animal.

The quality Of the milk of spayed
COW is admitted TO be superior. The
milk Of cows Ear advanced in pregnancy
was analysed by LAssAiGNE, and found

milk, or tactic acid, bu. much albumen
and uncombined soda. lie analy zed the
milk of the same cows after parurilion,
and found the first three named substan-
ces, but no albumen. Physicians have
pronounced against the use Of the milk
for babes taken from the cow in state
of CESSATION. The spayed animal is
more amiably disposed, always kind,
and having 20 season of heat. it kept
alone never breaks her enclosure. The
writer is assured shat she gives greater
quantity ofmilk, varying with the season,
as matter depending on the season.
Those who have fa,ied these cows for
beef, assure Us they are fatted quicker.
and that The beef is better. As TO the
length of time they will give milk, DR..

years; others have stated i, to be seven
and eigh. years. None have pronounced
against the operation. or have deemed
the animal less valuable if j, be preferred
to put her in beef in four years. We
have only 10 think Of the expense OF
winiering dry COW, as an oilse. to such
necessity. Boston Cuitivator.
