CHAPTER IX

THE FARROWING SOW

The pregnant sow usually carries her pigs about sixteen weeks. The

variations are neither great nor numerous, when they do occur it is

usually with sows with their first litters or aged sows which sometimes

farrow ere the full time has expired, or with robust sows in good

condition which occasionally carry their young beyond the one hundred

and twelve days which may be taken as the average period.

We assume that each owner of a breeding sow keeps a record of the date

of service of the sow in order that the necessary preparation of the

sty, etc., can be made in readiness for the arrival of the expected

litter. Even when this wise precaution is neglected nature gives a

sufficient warning to the observant owner. Apart from the increasing

size of the body, the udder gradually becomes more prominent, and each

pap becomes more defined, the vulva becomes enlarged and the muscles on

either side of the tail fall away and lose their tenseness, whilst in

the vast majority of cases milk appears in the udder some twelve hours

before the arrival of the pigs. The teats shine and become more

prominent, the presence of milk is easily ascertained by gently

pressing the teat between the finger and thumb.

Another certain indication of the early arrival of a family is the act

of the sow carrying straw about in her mouth wherewith to make her

farrowing bed.

One of the chief causes of trouble with the farrowing sow arises from

the sow not having been allowed to take sufficient exercise. Of course,

the best of all systems is to allow the sow its complete freedom at all

seasons of the year save when she is within about a fortnight of her

time, and when she is rearing a litter of pigs. Even if there be no

grass field or paddock in which she is able to pick up a good portion of

her living, or a roadside where she can get a few blades of grass, an

open yard is infinitely better than the confinement of a sty, as apart

from the reduction in the cost of keep, the sow will produce stronger

pigs, and have a decidedly easier time of farrowing.

In the case of a sow showing a disinclination to take a sufficiency of

exercise either owing to laziness, to high condition, or heaviness of

body, it is advisable to exercise her by walking her about quietly for a

short time each morning and evening before and after the heat of the day

has become excessive, or has passed off.

There is a difference of opinion amongst pig breeders as to the

desirability or the reverse of having someone in attendance on the sow

during the time she is farrowing. Those who object to this procedure do

so on the ground that the presence of a man simply tends to irritate the

sow, and to frequently cause her to become restless, with the result

that the little pigs are trodden upon or become laid upon and killed.

This view is generally held by those who are not particularly fond of

animals, as evidenced by that occasional intercourse between pig and

owner which consists of rubbing the head of the pig, or scratching its

side, when in response to the pleasant sensation it rolls over on to its

side like Oliver and asks for more. The trouble if any, which arises

from the owner or pig man being in the sty with the farrowing sow almost

invariably arises from the absence of a sympathetic feeling between the

two. Sows, and indeed wellnigh all animals, pine for sympathy and

company, and no animal more so than a pig. Still there are very

occasional instances where the young sow becomes very excitable as she

commences to farrow even when she and her owner or attendant have

previously been on the best of terms. But there the cause is not the

presence of a human being, but the arrival of one of her own little

pigs. So long as the pigling remains quiet there is peace, but as soon

as the youngster endeavours to get to the teat and especially if in the

endeavour it utters a cry or a squeak, the young sow will jump up from

her nest and endeavour to seize the youngster in her mouth, when unless

prevented the sow quickly squeezes all life out of the pig; and in some

cases when the pressure has been so severe as to break the skin of the

piglet, and the sow tastes blood, she will proceed to eat the dead pig.

When affairs have arrived at this sad state, the chances of the

remaining pigs having a pleasant reception into the world are

comparatively slight.

When there exists a good understanding between the sow and attendant, as

there invariably is when the latter is not rough and unkind, as only bad

tempered men can be, the trouble in a case such as just referred to is

greatly reduced, as the attendant runs no risk in entering the sty and

in removing the little pigs as they arrive, and placing them in a hamper

or box partially filled with straw until such time as the sow has

completed her farrowing, when the pigs can be placed against the sow's

udder, and providing they do not bite her, all will settle down in peace

and comfort.

In order to avoid the slightest risk of trouble it is advisable when the

pigs are apart from the sow to break off with a pair of pliers the four

little teeth with which the pigs are endowed prior to their birth. Care

being taken to remove the pigs beyond the hearing of the sow each little

pig in turn is tucked under the left arm, the mouth is opened by the

left hand, and the teeth pressed hard with the pliers, or even a slight

turn of the wrist given, when necessary, and the brittle teeth are

crushed.

As soon as the placenta or afterbirth is ejected this should be removed.

A little slop food should be fed to the sow, and whilst she is eating

it, the wettest part of the bedding should be replaced by a little short

and dry straw just enough to render the nest comfortable for the little

pigs. The nest should be disturbed as little as possible, as should the

whole of it be removed and fresh straw given, the sow will probably

spend a considerable time in remaking the nest, and in the meantime the

little pigs will be in danger from a chill, or in being mixed up in the

straw and being laid upon. The risk from delay in the sow laying down

and suckling her pigs is much greater in cold weather, as not only will

they become chilled, but they will persist in crowding round the sow and

so run the greater risk of being trodden upon, or rolled up in the

bedding in the effort of the sow to remake her comfortable nest.

Some persons strongly recommend the giving of a strong dose of medicine

to the sow after she has farrowed. In ordinary cases this is not

necessary, the farrowing of a litter of pigs is a simple and natural

operation. In those occasional instances where manual assistance has to

be given to the sow owing to the unusual size of the pig, or wrong

presentation, or even of a pig which has been dead for a day or two and

has begun to decompose and consequently to increase in bulk, it is

advisable to give medicine to the sow, since there is every probability

of some amount of inflammation due to the insertion of the hand. As the

sow's bowels are likely to be somewhat constipated it is always

advisable to exercise her for a few minutes during the morning after she

has farrowed. In most cases the exercise will at once cause her to

relieve her bowels and her bladder, when she can be returned to her sty.

We found sharps, or the finest portion of miller's offals (which usually

go by varying names in different parts of the country), the most

suitable food for newly farrowed sows, and until the pigs were at least

four weeks old. Some persons recommend that a portion of the food should

consist of bran, this on two grounds--the first that its use tends to

prevent constipation, and secondly on account of the food analysis which

it gives. Our experience has been that when sharps are fed to the sow no

trouble should arise from constipation, whilst as to the nutriment which

bran contains the claim may be good, but the pig is unable to extract

it; so large a proportion of the bran passes through the pig in an

undigested condition. As a rule the pig, unlike the horse, cow, or

sheep, does not masticate its food, nor does it, like the two last

named, chew its cud, but it usually bolts its food, and thus casts a

greater labour on its digestive organs which have neither the time nor

power to extract the whole of the nutriment from the bran. In addition

to this, bran tends to too great looseness of the bowels, which in the

case of young pigs tends to become diarrh[oe]a.

There is a tendency on the part of some pigmen who are over anxious to

succeed to feed the sow too large a quantity of food during the first

ten days or so after she has farrowed. During this period the demand on

the sow is really not much greater than it was during the last two or

three weeks of carrying the pigs. As the pigs grow older an increased

supply of food is necessary, but for a week or two after the arrival of

the pigs twice feeding of the sow should suffice unless she is very low

in condition, or a very large litter of pigs is left on her. In such

cases it may be advisable to feed her three times per day just as much

as she will promptly clear up. It is a great mistake to give so much

food at one time that a portion is left over in the trough,

particularly is this so when the pigs are over three weeks old, as

nothing so quickly upsets the stomachs of the youngsters as sour food.

If in ordinary cases feeding the sow three times daily is persisted in,

the same quantity of food given should simply be distributed over the

three feedings, as an excess of food is only less a mistake than

underfeeding.

Three of the most common troubles with young pigs are diarrh[oe]a, fits,

and loss of the tail. There is a belief amongst many old pigmen that

every litter of pigs is bound to have at least one attack of diarrh[oe]a

ere it is weaned. They look upon it as a fatality which is certain to

eventuate, no matter what steps may be taken. Of course, this is folly.

The liability of little pigs to an attack of what is commonly called

scouring is great as the causes are several, amongst them the greatest

is perhaps a chill which may arise from draughts owing to faulty

construction of the sty doors or ventilators neglected; insufficient,

unsuitable, or damp bedding; neglect of proper sanitation, or the

frequent cleaning out of the sty; and most frequently of all from

injudicious feeding of the sow. In fact, anything which affects the

health of the young pig to any great extent appears to result in

indigestion, which causes constipation, and this in turn nature

endeavours to remove by a special effort which softens the faeces

somewhat. On removal of the cause of the constipation, the bowels

perform their duty normally, but if this be not removed the result is

diarrh[oe]a, which again if continued for any length of time often

becomes dysentery, when the fever is acute; the pigling neglects its

mother's teat, and instead sucks up any moisture however foul which it

can find in the sty. This is almost invariably a precursor of death.

From the above it will be gathered that prevention is better than cure.

In case of an attack, the first thing is to discover the cause, and the

second is to remove it, when, generally speaking, the trouble ceases. As

a help to this end, depriving the sow of one meal is recommended. Coal,

cinders, or even earth will be readily eaten by the young pigs and prove

of benefit. Medicine is not often required if the steps recommended are

promptly taken.

In our earlier days hog's madder was the common medicine used with pigs

for most ailments, but of late years sulphur appears to have taken its

place. It is less violent than castor oil, which is apt to cause

constipation of the bowels after its first effect has passed off.

The soreness of the tails, which if not attended to generally results in

the pig becoming bob-tailed, appears most generally in damp and cold

weather, and is the result of impaired circulation of the blood. The

cure is simple. The application of fat or oil as soon as the tail

becomes red and cold, twice per day, and continued for two or three days

will almost always result in a cure. For some years we used

boro-glyceride, a compound, we believe, of boracic acid and glycerine,

but we are not certain that it is now procurable.

The third of the common troubles of the young pig is fits of an

apoplectic and epileptic character. As a rule the shortest, thickest,

and fattest pigs of the litter are those which are affected. This

points to the chief cause, too much food in the form of mother's milk. A

reduction in the quantity of the food fed to the sow will generally be

effectual, except when the pigs are old enough to eat. Then both the

quantity and the quality of the food given to them should be reduced.

Prompt removal of the cause is usually sufficient, but it may be

necessary to mix a little medicine in the food in persistent cases, or

when remedial measures are not promptly taken. The ordinary symptoms are

unmistakable, the pig falls on its side, struggles and gasps for breath,

then in a minute or two it rises and appears to be little the worse.

Unless continued over a period, fits are not usually fatal.

Very occasionally young pigs suffer from the protrusion of the rectum,

or as it is commonly termed "shooting of the gut." This is due to

various causes which result in straining. Of these constipation and

diarrh[oe]a are the two most common. As soon as the protrusion of the

gut is noticeable, the enlargement should be carefully washed, then

oiled and gently pressed back into its natural position. Some pigmen

advise the dusting of flour on to the protruded portion before it is

returned, but there is a risk of increasing the amount of inflammation

which is generally present. If known the original cause of the trouble

should be removed, but in any case it is advisable not to give any solid

food to the pig for two or three days after the operation.

Still another of the troubles to which pig flesh is heir is hernia, or

rupture. This is of two kinds, umbilical and scrotum. The former is

the escape of a portion of the bowels through an imperfectly closed

navel opening, whilst the latter shows itself in an enlargement of the

scrotum or purse due to an escape into it of a portion of the abdominal

contents. Both of these ailments are considered to be hereditary, but

the most common and the most troublesome is the latter, since there is

always a chance of strangulation of the escaped portions, which nearly

always results in death.

At one time it was considered to be inadvisable to castrate the boar

pigs affected, but of late years the plan has been adopted of making

only one incision in the scrotum in place of two, and making that one as

high as possible. Then after the operation is performed, the aperture is

sown up. The pig should be fed lightly for a day or two in order to give

time for the healing of the wound.

Umbilical hernia is not generally of much importance, the navel opening

gradually closes as the pig grows stronger and the enlargement

disappears. It is advisable not to breed from a sow pig which has been

affected, nor to continue to use a boar which has begotten ruptured

pigs, as both failings are hereditary.

For a time at least, there is certain to be a difficulty in obtaining a

full supply of sharps, even of the greatly reduced feeding value of the

present quantity available. It may, therefore, be advisable to refer to

another system of feeding the suckling sow and the young pigs. It is now

perforce being generally adopted, but the result is not generally

considered to be equal to the old system recommended. It is that of

feeding pigs of the kind mentioned on vegetable food, and a mixture of

palm nut, cocoa nut, ground nut, or linseed cake. The proportions fed at

the Cambridge University Farm are mangolds 20 lbs.; a mixture of two

parts palm nut cake, and one part cocoa nut cake, 2 lbs.; linseed cake,

2 lbs.; and ground nut cake, 1 lb. The two former were fed in the

morning and evening, and the other two at midday. The various cakes seem

to have been fed in a dry condition, but other pig feeders have found it

beneficial to soak the cake in water for some twelve hours. This view

seems to have received support from the practice at Cambridge, which was

to mix the cake with the cut mangolds twenty-four hours before being fed

to the pigs so that at least a portion of the cake would become softened

by the mangold juice. Almost any kind of vegetable matter containing a

fair amount of nutrition would be equally as suitable as mangold, indeed

more so during the period from October to April. In the winter months

cooked potatoes; kohl rabi, swedes, parsnips, cabbages, artichokes,

etc., fed raw; and in the summer grass, lucerne, clover, vetches, rape,

or almost any kind of vegetable food will be readily eaten by the pigs.

Even where the wasteful practice of peeling the potatoes before being

cooked for the household is still followed (and just how wasteful this

old-fashioned plan is has been lately proved to be a loss of nearly one

quarter of the nutriment)--it is advisable to boil the parings and then

mix the whole with the pig's food.

It cannot be too strongly impressed on pig keepers that a certain

proportion of vegetable food is most beneficial for pigs of all ages, as

not only is a saving in cost effected, but the pigs will continue in a

more healthy condition than when fed solely on meal or other

concentrated food.
