A
Plant And Animal Considerations For Graziers
(Continued from Page 19)
ing plants also are more
likely to produce the poison.
Feeding or grazing of these
forages should be delayed
until they are more mature.
Feeding forages following
heavy nitrogen fertilization,
plant injury by trampling or
stunting of plant growth due
to adverse weather should be
avoided. If large amounts of
forages ' containing prussic
acid are eaten, death can
occur within a few minutes.
Excess salivation, difficult
breathing, muscle tremors
and rapid heart rate all signal
the onset ot prussic acid poi
soning. Shortly after these
symptoms are seen the
animal may go down and
death will likely occur due to
respiratory paralysis.

two hours after the onset of

these signs will usually re-
cover,
Prussic acid is quite vola
tile and there is little danger
from feeding well-cured hay.
However, ensiling affected
forages does not appear to
make it safe to feed. The fol
lowing prevention measures
will best control the problem:
n Do not graze pastures that
are less than 18-24 inches tall
or green chop plants over 18
inches tall for three days after
a killing frost.
Do not green chop plants
less than 18 inches tall for
three weeks after a killing
frost.
Feed grain befoie allowing
animals to graze fields that
may be high in prussic acid.
Pasture bloat is usually
caused by the consumption of
young growing legumes in
the pre-bloom stage. Alfalfa

volved. Cattle in early stage
of bloat will show signs of at
dominal pain, which includ
restlessness and kicking a
the belly.
The left side of the anima
will usually appear distendei
and swollen. In advance*
cases severe distension of th
abdominal cavity will b
seen. Animals with sever
bloat will often exhibit diffi
cult open-mouthed breathing
and in many cases they will
be down.
The first indication that a
problem exists may be the
discovery of one or more
dead animals in the pasture.
Pasture bloat is usually of
the frothy type and cannot be
relieved by passage of a stom
ach tube alone. Bland oils,
detergents and/or special
chemicals such as poloxalene
are usually required to free
the gas from the rumen.
Prevention of pasture bloat
includes pre-feeding hay or
othe. - feed before turning ani
mals into legume pastures,
limiting access to legume pas
tures until animals are
adapted to the new feed, or
mowing the field and allow
ing one or two days before
pasturing.
Using oils, detergents or
poloxalene for preventing is
only effective if given the
same day that the problem
forage will be eaten and may
not be economically feasible
in many management situa
tions. Legumes tend to pro
duce gas in the equine
digestive system.
Horse do not bloat but do
colic, just another name for a
severe stomachache.
