It has been contended that our varioustypes had a common origin in the wildhog, and that the difference in form,

Trang 10

colour, and character amongst the localbreeds is due, in the main, to therequirements, imaginary or real, of theinterested residents in the particulardistricts On the other hand, it is assertedwith equal confidence, and probably withthe same amount of actual proof, that itwould be impossible so to improve thewild hog by selection as to render it theequal of the domesticated hog There must,therefore, have been an infusion of blood

of a cultivated breed of pigs to acquireeven that amount of success which wasnoticeable in the improved pig of acentury, or less, ago Unfortunately, forthis argument, it has not been possible toobtain any information of value as to thealleged source of origin of this cultivatedbreed of pigs

Trang 11

Again, those pigs which possess in amarked degree early maturity, fine quality

of flesh, and those other characteristics ofthe improved pig, are so various incolour, that one cultivated breed onlycould not have been utilised in the generalimprovement

All the ancient writers on pigs appear tohave experienced the same difficulty whenendeavouring to discover the sources oforigin of the material which might havebeen used in the production of the pigwhich in their time was looked upon asthe domesticated and improved pig of theperiod This difficulty extends even to thepresent day So far as is known thereexists no actual proof that thedomesticated hog has been evolved in any

Trang 12

particular way other than by continuedselection of those animals for breedingpurposes which possessed in the greatestdegree those particular qualities held inthe highest estimation at the time.

Of course, the soil, climate, etc., of thedistrict in which pigs are reared have acertain amount of influence, but this isnoticeable to a much lesser extent withpigs than with horses, cattle, or sheep,since under the present system of pig-breeding the greater portion of the foodused in the different districts is of a verysimilar character—indeed, much of it has

a common origin—having been importedfrom abroad

As a rule, comparatively speaking verylittle difference is noticeable in the

Trang 13

development, form, and character of pigsbred in the various parts of the country,whereas with some of the otherdomesticated animals a very considerablechange follows the removal of sheep of apure breed from one district to another.The quality and quantity of the wool,flesh, and bone are all affected Anexactly similar effect is noticeable whenhorses of a particular breed are movedfrom one district to another For instance,

a Shire foal bred in the Fens may possessthe characteristic bone, flesh, and hair, yet

if it be moved into portions of the Easterncounties where the soil is of a totallydifferent character, it will when maturedhave lost, to a very considerable extent,its peculiar characteristics of bone andhair The changes wrought may be due in

Trang 14

small measure to climate, but thepredominant cause must be due to thevariation in the food grown on soils of adifferent character.

This question of the original cause orcauses of the varying colour of the pigs indifferent localities appears to be equallydifficult of solution As to the continuation

in certain districts of pigs of one colour,custom and even prejudice have a greateffect So strong is this prejudice thatsome persons will even declare that thepork of pigs of the fashionable colour inthe neighbourhood is superior to that frompigs of any other colour As this weakness

is common in districts where black andwhere white pigs are kept it must beadmitted that prejudice alone must be the

Trang 15

foundation of the belief.

Probably the safest conclusion to arrive atwith respect to the variation in colour ofthe pigs noticeable in certain districts isthat in the long ago the native pig in thewild state was of the colour of the soiland the herbage in which it sheltered, andwas thus less conspicuous to its enemies,whether human or animal A markedinstance of this is to be found in the colour

of the common or original pig found insome parts of the country where the soil is

of a decidedly red colour In the districtreferred to one actually hears some farmsspoken of as "red land farms." What morenatural than to find in the districts inwhich land of this hue predominates thatthe pigs should be a red rusty hue such as

Trang 16

was the original colour of that breed ofpigs now called the Tamworth breed.Some persons, who do not agree with thistheory of the origin of the variouscoloured pigs, cite as a proof of theirbelief the fact that in so many districts thepigs are of a mixed colour, and that thispeculiar marking is equally as general inlocalities as is any particular or specialcolour in the pigs This is perfectly true,and it is probably due to exactly the samecauses, fancy, prejudice, or custom Theresidents in certain districts have grownaccustomed to certain things or certainforms, and are loth to change; themanufacturer of any article must humourthe actual or fancied requirements of hiscustomers if he is to secure success; and

Trang 17

in a similar manner the breeder of pigs has

to consider and to produce pigs of theform, size, and colour which are most indemand Further if, as confidently alleged,there is a preference in some districts forpork from pigs of a certain colour, then thebutcher naturally offers a higher price forpigs of that colour which most fully satisfythe fancies of his customers, and thus wefind a similarity of form and colour in thepigs of various districts

As to the origin of these parti-colouredpigs, the explanation offered is that even

in pre-railway times there was a certainamount of interchange of the differentlocal breeds of stock This would beaffected in various ways, which need not

be specified

Trang 18

At the present time we have severaldefined and distinct breeds of pigs whichhave secured recognition at our principalagricultural shows Indeed it may beclaimed that the exhibitions of live stockwhich have become so general in all parts

of the country have been one of the chieffactors in fixing to a certain extent the typeand character of certain local breeds.Within the memory of the present writerthe classification of pigs at our principalshows was of a very simple character; itconsisted of classes for pigs of a whitecolour and for pigs of any other colour.There was no attempt at any definition as

to size, form, and quality of the pigs.These points were left entirely to thejudges, who naturally were led to favourpigs of the type which they bred There

Trang 19

was thus a greater amount of uncertainty

as to the success of an exhibitor's stockthan at the present time This uncertainty—save as to the members of the ShowCommittees or their friends—wasincreased by the unfair system ofwithholding from the knowledge of theaverage exhibitor the names of thoseselected to judge

The necessity of some definition, if only

of colour, quickly became obvious Atfirst classes were established for pigs ofcertain colours; then the prizes wereoffered for pigs of certain breeds, whichwere more or less loosely defined Now

at the chief shows the pigs exhibited in thevarious classes must be qualified for entry

in the herd books of the particular breeds

Trang 20

At the Royal Agricultural Shows therehave been classes for pigs of the LargeWhite, Middle White, Berkshire,Tamworth, Large Black and LincolnshireCurly Coated breeds; whilst for the nextshow classes for pigs of the so-calledGloucestershire Old Spots breed are to beincluded As showing the changes whichare in progress it may be noted that twobreeds of pigs which had classesprovided for them at the Royal and someother Shows have become extinct Thesewere the Small White and the Small Blackbreeds—the sole cause of theirdisappearance being the unsuitability ofthe pigs of the breeds to supply the presentrequirements of the consumer.

THE PIG

CHAPTER I NON-PEDIGREE PIGS

Although the more general use of called pedigree pigs has tended to modifythe characteristics of the various localbreeds of pigs, yet it is possible to find acertain number of pig breeders whoadhere to the type of pig which has been inthe past most generally found in theirdistrict This type was undoubtedly fixed

so-by the wants or fancies of those resident inthe particular portions of the country

Trang 25

In the past it has been the practice whendescribing these local breeds to write asthough they were confined to certaincounties It may be that pigs of a peculiar

or characteristic type are more numerouswithin the borders of various counties, butthis is by no means always the case Thehabits and pursuits of the inhabitantsrather than the soil and climate—as withhorses, cattle and sheep—have thegreatest influence on the form, size andquality of the local pigs, whilst use andcustom appear to determine the colour ofthe pig We are of opinion that it will bemore instructive if we give a shortdescription of some of the more commontypes of these local breeds of pigs, andmention the names of those counties inwhich they are more generally found

Trang 26

Amongst the most distinct of these localbreeds is that which is variously termedthe sheeted or saddle-backed pig, which

in the United States has a society to lookafter its interests, and where it bears thename of

The Hampshire

Just why our American cousins shouldhave decided to call these sheeted pigsHampshires is not on the surface, since theoldest writers on pigs give to the county ofSussex the credit of being their originalhome The description given by Sidney ofthe Hampshire pig is that "it is a coarseand useful black pig, inferior to theBerkshire, and not in the same refinedclass as the Essex." Richardson writes

Trang 27

"The Hampshire breed is not infrequentlyconfounded with the Berkshire; but itsbody is longer and its sides flatter; thehead is long and the snout sharp Thecolour of the breed is usually darkspotted; but it is sometimes blackaltogether, and more frequently white."The sheeted pig has also been bred in thecounty of Essex for over a century, but it

is recorded that it was introduced into thiscounty by a Mr Western whosubsequently became Lord Western, andwhose estate was situated in Essex

In Sidney's book The Pig, we read, "West

Sussex, Hampshire, Berkshire, Dorset,Shropshire and Wales had indigenousblack or red and black breeds of swine;and between the whites, the blacks and the

Trang 28

reds the parti-colours were producedwhich have since in a great degreedisappeared under the influence of prizes,generally awarded to pure breeds ofsingle colours."

Sidney also states "that Youatt and all theauthors who have followed him down tothe latest work published on the subject,occupy space in describing various countypigs which have long ceased to possess, ifthey ever possessed, any merit worth theattention of the breeder."

The Rudgwick, which is another name forthe sheeted pig, is included in the list.Richardson at a still earlier date describesthe Sussex breed as "black and white in

colour, but not spotted; that is to say, these

colours are distributed in very large

Trang 29

patches; one half—say, for instance, thefore part of the body white and the hinderend black; or sometimes both ends black

and the middle white or vice versâ; these

pigs are in no way remarkable; theyseldom feed to over twenty stone Theyare well made, of middle size, and theirskin covered with scanty bristles Thesnout tapering and firm, the ears uprightand pointed, the jowl deep and the bodycompactly round They arrive at earlymaturity, fatten quickly, and the flesh isexcellent."

Richardson also writes, "There is anotherimproved Essex breed, called the EssexHalf-Blacks, resembling that which I havedescribed in colour, said to be descendedfrom the Berkshire This breed was

Trang 30

originally introduced by Lord Western,and obtained much celebrity," etc etc.

He then quotes from The Complete

Grazier, sixth edition, as follows: "They

are black and white, short haired, fineskinned with smaller heads and ears thanthe Berkshire, but feathered with insidehair which is a distinctive mark of both;have short snubby noses, very fine bone,broad and deep in the belly, full in thehind quarters, but light in the bone andoffal They feed remarkably fast and are of

an excellent quality of meat The sows aregood breeders, and bring litters of fromeight to twelve; but they have the character

of being bad nurses." If this allegationwere true at the time it was written, it isnot at the present time as the Half-Blacks

Trang 31

or sheeted sows are both prolific andfirst-rate mothers.

Malden describes the Sussex: "A largebreed called the Rudgwick, was one of thelargest in England There appears to be adoubt as to whether the coloured pig wasdescended from the spotted Berkshire orthe black and white Essex They were ofmedium size, of good quality generally,but of somewhat heavy bone." Thegenerally accepted view is that the Essexsheeted pig was descended fromimportations from the county of Sussex.These sheeted pigs are still occasionallymet with in Essex, but the system ofcrossing which is generally followed bypig breeders in the county is graduallyreducing its number, although even

Trang 32

amongst the cross-breeds the peculiarmarking occasionally shows itself At thetime of writing there is a movement onfoot to form a society for the purpose ofreviving the breed From the utility point

of view the sheeted pig has much torecommend it, but whether or not one ormore of the breeds of pigs whosepedigrees are already recorded do notpossess at least equal merits must be leftfor decision by others

Spotted Pigs

In many districts are found other coloured pigs, but in these the black, thewhite, and the red colours showthemselves in spots of varying size andextent Probably amongst the best types of

Trang 33

parti-these spotted pigs is the one found overthe greater part of the county ofNorthampton, and portions of the counties

of Leicester and Oxford adjoining In theformer county the pigs have more of blackthan white in their colouring, whilst in thetwo latter red spots are more often seen.This is probably due to a stronger infusion

of the blood of the Staffordshire red pigwhich is now known as the Tamworth.The blood of the Neapolitan pig throughthe Berkshire or the Small Black iscredited with being the origin of thedarker coloured Northamptonshire spottedpig The qualities claimed for thesespotted or "plum pudding" pigs as they arelocally termed, are prolificacy, quickgrowth, hardihood, and the production ofpork possessing a large proportion of lean

Trang 34

to fat meat They are also good grazers,and grow to a size quite the equal of theBerkshire In form they are perhaps moresuited for the fresh pork trade than for themanufacture of bacon of the kind now somuch in demand.

The Large White and Blue Pigs

Those large, coarse-boned pigs with hair

of a white colour and skins more or lessmottled with blue are gradually givingplace to pigs with finer hair, skin, bone,and quality of meat The coarse lop earsare being reduced in size and thickness,whilst the pig itself is becoming less gauntand its early maturity considerablyincreased by crossing with the betterquality Large White and the quickly

Trang 35

maturing Middle White These coarsewhite with blue markings pigs werecommon in the Fens of Cambridgeshire,Norfolk, the Isle of Ely and Lincolnshire,and in the counties of Bedford, Cheshire,etc.

White Pigs

Within the memory of persons now living,white pigs of varying types were found invarious parts of this country Many ofthese white pigs found in Norfolk, Suffolk,Shropshire, and Wales had little torecommend them as they were flat sided,long legged, hard feeders, and required to

be comparatively old before they could beturned into pork A vast improvement has

of late years been effected in these

Trang 36

unprofitable swine by crossing them withcompact and early maturing pigs ofdifferent colours, but mainly white pigsuntil the last few years, when LargeBlacks and even a few GloucestershireOld Spots boars have been introduced inNorfolk.

At one time white pigs of a small sizewere by no means uncommon in Suffolk,Essex, Middlesex, Yorkshire, and parts ofBerkshire, and other counties The origin

of these small, compact, and earlymaturing pigs appears to have been across of the imported Chinese on theneater and shorter country pigs of a whitecolour For a period these handsome pigswere quite fashionable amongst the well-to-do, but the general public objected to

Trang 37

the pork produced by them, owing to itsexcessive fatness The bacon curers stillmore strongly objected to the short sidesand the very small amount of lean meat inthe cured carcases During the last thirtyyears comparatively few of these pretty,but useless, pigs have been bred.

Black Pigs

The description given of the two maintypes of white pigs would apply equallywell to the Black pigs common in thiscountry, save with respect to colour Thelong flat-sided black pig was found inEssex, Suffolk, Cambridgeshire, Sussex,etc These pigs were noted for theirprolificacy, hardihood, and quick growth,whilst the sows furnished a full supply of

Trang 38

milk to their youngsters, but they weresuch slow feeders that it becamenecessary to cross them with pigs whichmatured more quickly A type of black pigsimilar in form to the Small White wasalso found in Essex and Suffolk, whilst inDevonshire, Dorset, and one or two othercounties the colour of the pigs was bluerather than black, and of a somewhatlarger size, but possessing the sameweakness, too large a proportion of fat tolean meat.

CHAPTER II PURE BREEDS

Trang 39

The task of writing a description of thevarious breeds of swine has beenrendered less difficult by the formationduring the past half-century of societiesfor the registration of the pedigrees of thepigs of the different breeds, and by thesetting up of scales of those points whichpigs for entry in the particular herd booksshould possess The first of these societieswas the National Pig BreedersAssociation, of which the present writerwas the honorary secretary for two years.

At the time of its formation the breeds ofpigs most generally recognised were theBerkshire, the Large, Middle, and SmallWhites or Yorkshires, and the SmallBlack breed It was intended that thepedigrees of the pure bred pigs of each ofthese breeds should be recorded by the

Trang 40

Association and published in one herdbook.

There is no doubt that this would havebeen an ideal plan, and would haveresulted in a saving of much labour andexpense, and decidedly more convenientfor those connected with the export trade.For reasons into which it is not nownecessary to enter, the breeders ofBerkshires determined to have a separateherd book; therefore, they started a societywhich they named the British BerkshireSociety, to distinguish it from theAmerican Berkshire Record

Subsequently the Tamworth breed of pigsbecame recognised by the RoyalAgricultural Society, and the breeders ofthe red pig joined the National Pig
