On the other hand, there are many practical pig keepers who make it a rule to delay the mating of their young sows beyond the eight months'
age. They contend that a sow pig at eight months is not sufficiently matured to bear the strain of producing a litter of pigs when she is about one year old, and then to furnish the pigs with a sufficiency of milk to give them a good start in life. The plan which they adopt is to mate the sow when she is about a year old so that she is some sixteen months old before her family troubles commence.
Another very curious reason has been recently made public by an enthusiastic novice for delaying the mating of the yelt until she is at least a year old. It is the following, that it is quite possible to ensure that the produce of young sows which have reached the age of sixteen or seventeen months ere they farrow their first litter shall possess the desired characteristics of the breed, whereas this is by no means certain if the young pigs arrive before the sow has reached that age or is about a year old. Unfortunately, we have see no attempt made to account for this alleged curious variation in the qualities inherited from a parent of about one year old and the parent which had arrived at the more matured age of about sixteen months, so that it is impossible to discover a solution of the strange problem.
Therefore, we should be unable to admit the correctness of the a.s.sertion even though it was not directly in opposition to our belief which is founded on experience of a most extensive character extending over some sixty years. To aver that the power of a young sow to impress its hereditary characteristics on its young are only fully developed by deferring the arrival of the young pigs for four or five months, or until the sow is sixteen instead of twelve months old when she farrows must surely cause surprise, if not, disbelief. Perhaps the object of the propounder of the theory was to create a discussion--it could not have been to bring his name prominently before the public.
Another advantage in mating the young sow so that her first litter appears when she is about a year old, her daughters will in turn farrow during the most suitable months of the year, providing of course that she herself had been farrowed in early spring or about the month of July.
When the sow pig which is intended to be kept for breeding has been farrowed in some other part of the year, it is advisable to defer beyond the eight months the mating of her so that she farrows at the best times, or perhaps even better than that, if the pigs are not intended for breeding purposes, would it be to have the sow mated when she is about eight months old, and then allow the pigs to remain on the sow a few weeks beyond the usual period of eight weeks so that the pigs are taken off the sow three or four days before it is desired to have her again mated with the boar. The risk of the sow returning to the boar will be minimised, as a sow which has been baulked is sometimes difficult to settle. In addition, the sow will be stronger and more vigorous and likely to produce a strong litter of pigs, whilst the piglings will scarcely miss their mother's milk when they are weaned from her.
Those pig breeders who are in favour of withholding the boar from the young sow until she is about a year old aver that early mating results in the sow becoming worn out and useless for breeding at a much younger age than if she be not mated until she is well matured. This is not in accordance with the writer's experience, as many of his sows which farrowed their first litter when they were about a year old continued to breed regularly until they were six or seven years old--indeed, one Middle White, Holywell Victoria Countess farrowed her last litter when she was in her eleventh year. This sow also disproved the confident a.s.sertion that the showing of sows renders them comparatively useless for breeding purposes, since she not only continued to rear her pigs well, but she produced a number of most successful prize winning boars and sows, and also won many prizes herself from the age of five months to five years.
The princ.i.p.al cause of premature old age amongst sows is not due to their being first mated when they are eight months old, but to the want of care in the management and feeding of the sow during her pregnancy and whilst she is suckling her litter of pigs. To a sow with a good const.i.tution the act of breeding and rearing a family of pigs is only the most important act of nature which cannot be harmful to her, providing that she received that amount of proper food and attention which nature required.
There may be very occasional instances of harm being done to the breeding sow by over feeding, or rather by injudicious feeding, but in comparison there are hundreds of instances where under feeding and neglect are the cause of trouble and loss.
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 a.s.sume 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 v.u.l.v.a 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 s.h.i.+ne 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 gra.s.s 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 gra.s.s, 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 pa.s.sed 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 a.s.sistance 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 a.n.a.lysis 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 pa.s.ses 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 diarrha.
