_ CHAPTER VI. SELECTION OF THE SOW It is impossible to agree with the view held by so many persons that the necessity for the same care is non-existent in the selection of a sow as in the choice of a boar. We hold that the desirability for studying the forbears, especially the dam, of a young sow intended for breeding purposes is fully as great as when selecting the young boar, since many, if not most, of the qualities which we desire the brood sow to possess are strongly hereditary. Take, for instance, the question of gentleness or a quiet disposition, it follows from dam to produce with a regularity equal to that of bad temper, and the latter is wellnigh a certainty. Again, whoever found that the female produce of a sow deficient in the maternal instincts proved, if saved for breeding purposes, to be a really good mother? As a rule the daughters of a sow which gives but a small quantity of milk, and that of an inferior quality, are also cursed with the same grievous failings, but this does not appear to be universally the case, since the milking qualities of the dam descend through her sons, so that if the female progenitors of the boar have been good milkers it is probable that the boar's daughters may be able to rear their pigs successfully, even if their dam had not been in the habit of suckling her pigs well. Still, it is quite safe to assert that with this one exception we may fairly anticipate that the good qualities which we seek in a sow are far more likely to be found in the sow pigs of a sow herself the possessor, than from one which does not possess them. We are inclined to the belief that the alleged failure of some pedigree yelts to make good brood sows is in the main due to the continued selection for breeding purposes of those pure-bred yelts which show early maturing and flesh-forming qualities, rather than that motherly look which is almost invariably to be found in a sow which is prolific, a free milker, and a really good mother. There is a marked difference in the formation of a milk-giving and a fat-producing sow--the latter is generally somewhat heavy in the shoulders, has a muscular or fat neck, is rather short in the head and heavy in the jowl, and is altogether more compactly built, whereas a good brood sow has rather a long face, is wide between the eyes, has a light muscular neck, is fine in the shoulders, possesses long and square quarters and appears to be heavier in the hind than in the forequarters. She is somewhat more loosely built and often shows less of quality. Thickness of flank and length of side are desirable, the first as indicating substance and flesh, whilst the second gives plenty of room for her pigs to suck. The bone should be of good quality; the same remarks apply to the skin and hair. About half a century since there existed a fancy, which almost amounted to a craze for sows of small size; they could not be too neat, and showing too much so-called feminine character. The almost certain result of selecting the neatest of the female pigs followed, the fat pigs sent to market were light in weight, deficient in lean meat and rightly named "animated bladders of lard." Within about the same distance of time it was the common practice of exhibitors of pigs at the Smithfield Club's Shows to provide pillows in the form of round pieces of wood on which the fat pigs rested their heads so that these were raised in order to prevent the pigs becoming suffocated. In addition, the pigs were fed on forcing foods until they were at least one and a half year old and allowed to take, or were given little exercise, with the result that the pork consisted mainly of soft fat or lard. To such an extent had this craze for neatness been followed that the bacon curers and consumers of pork wellnigh ceased to purchase or consume pork. At the present time we are afraid that the tendency is in the opposite direction, and mere size is receiving far too much attention. At some of our agricultural shows the judges select for honour great unwieldly sows which could not possibly perform with any amount of success those maternal duties which a brood sow is supposed to be kept solely to perform. An extremely large sow is very frequently a poor milker, the quantity of milk she gives is not large, nor does she continue to give even this reduced supply for a period long enough to allow her young to grow strong enough to make a good start in life on their own account. Another great objection to a sow of extreme size is that her produce almost invariably take after her to such an extent that it is difficult, if not wellnigh impossible, to make them fat until they are from nine to twelve months old, and by that time they are too large and heavy for the general demand which is at the present time, and likely to become still more so in the future, for small joints of meat which carry a large proportion of lean and a limited quantity of bone. The most successful manufacturer is he who most nearly supplies the consumer with that which he requires or fancies. We are not moved by the contention of breeders of pedigree pigs that the most valuable pig is the one which possesses in the greatest degree those special points which are characteristic of the breed, as, for instance, size in the pigs of the Large White, the Large Black, and the Lincolnshire Curly Coated pigs, therefore the biggest pigs should be held in the highest esteem. In our opinion the best, as it is in the long run the most profitable, is the pig which furnishes to the greatest extent exactly the kind of meat in the most general demand. In addition to these objections to an extremely large and ungainly sow is the fact that such an one is invariably clumsy in the breeding pen, she is almost certain to lay on some of her pigs. It is even alleged that her period of usefulness as a breeder is shorter than that of a sow of ordinary size. _ |
