Pears: An Alternative Feed
JOHN M. HARPER, Livestock and Natural Resources Advisor,
University of California Cooperative Extension,
Mendocino and Lake Counties
In 2006 the pear industry in Lake and Mendocino
Counties experienced up to 30 percent crop losses
due to lack of qualified pickers to harvest the crop.
These losses may have been a one-time problem,
but cull pears happen every year and represent an
annual problem to the pear industry. While little can
be done to salvage the direct loss of high-grade fruit,
an opportunity exists for ruminant (cattle, sheep, or
goats) livestock producers to recoup some of this loss
by turning it into a quality feed source.
Fruits, unlike other crop residues that are univer-
sally low-quality roughages, are an excellent source
of energy for ruminant animals. Fresh pears used in a
cattle ration, for example, have TDN (total digestible
nutrients) values of 87 percent, which is the same as
46–48 bushel weight barley. Rations high in fresh pear
content must be supplemented with protein, miner-
als, and fiber content. In feeding trials with cattle in
California, it was noted that dry cows and 2-year-old
heifers consumed an average of 20 pounds of pears
daily without noticeable bad effects. In comparing
cattle responses to feeding on peaches and pears, the
animals seemed to find spoiled pears more objection-
able (Bath et al. 1980; NRC 1983).
Since pears are high-moisture content feeds (the
average pear dry matter is 17 percent), care must be
taken to insure that animals only consume half or
less of their ration’s dry matter from the high-mois-
ture feed. Ruminants will eat about 2.5 to 3.5 percent
of their body weight per day when the feed is in
a dry form such as hay and grains (90 percent dry
matter), but they cannot eat this much if it is high in
moisture content. The reason is one of rumen capac-
ity; the rumen (stomach) will not hold enough high-
moisture feed to fulfill the animal’s nutrient needs.
Many high-moisture feeds are often quite palatable,
and if given free choice, the animals will fill up on
such feeds to satisfy their appetites, resulting in
weight loss and reduced milk production (in lactat-
ing animals). The maximum dry matter intake of an
all-high-moisture ration is about 2 to 2.5 percent of
body weight.
Cull fruits, when fed in large amounts, can be very
laxative, so it is important to monitor their intake.
Feeding some dry forage prior to access to the fruit is
a good management idea. Cattle should be gradually
acclimated to the pears by feeding 2 or 3 pounds as
fed per day and increasing the amount 2 or 3 pounds
as fed per day per head until they are getting the
desired amounts. Smaller ruminants like sheep or
goats should be started on about half the amount for
cattle and increased proportionately. Usually fruit
harvested for human consumption has been handled
safely with respect to residual pesticides and would
be safe to feed to livestock. If the livestock producer
is unsure, have the fruit tested for pesticide residue
prior to feeding.
One of the biggest problems with feeding fresh
pears is their highly perishable nature. Two options to
address this problem are possible: drying the pears or
ensiling them. In the feeding trial mentioned above,
it was noted that a somewhat larger quantity of dried
pears than of dried peaches could be fed. In addition,
dried pears fed up to 4.5 pounds per day over a 10-day
period resulted in no noticeable loss of appetite and
no laxative effect. However, drying pears is expensive
in terms of energy expenditure. Making pear silage is
probably the better method for preserving this feed
resource. When pears that contain about 80% moisture
are ensiled for cattle, 20 to 25 pounds of dry hay, straw,
or chaff is run through the silage cutter with each 100
pounds of pears (Boyles 2000). The most economical
method of ensiling is with large, airtight plastic bags
commercially available for this purpose.
Timing is critical in salvaging pears for livestock
feed. If the weather turns hot, the fruit will spoil

before it can be fed or preserved through ensiling.
Spoiled fruit should not be fed.
So how would one calculate the value of fresh pears
or pear silage? In buying or selling feeds, sellers or pur-
chasers should check price against values received or
sold. An easy method is to calculate the cost per unit of
nutrients. Since pears would be considered an energy
feed, like barley, one can compare the cost per pound
of total digestible nutrients (TDN) to arrive at a com-
parable price for the pear feed. Since fresh pears and
barley are similar in TDN values (87 percent), checking
with the local feed store or mill on the price for barley
will give the seller and buyer a starting price for nego-
tiation. Of course, many other factors affect the actual
feeding value of each feed. The livestock producer will
also want to consider such things as palatability, grade
of feed, preparation of feed (such as ensiling), ingredi-
ents with which each feed is combined, and quantities
of each feed fed (Ensminger, 1978).
Savvy livestock producers with the land space and
skill may be able to look at cull pears or other unusual
feedstuffs as a method for reducing their feed bills or
extending their feed supplies. Savvy pear producers
may want to think about ensiling pears and produc-
ing secondary income by selling pear silage to live-
stock producers.
