Opfindelsen angår en fremgangsmåde til fodring af grise i stier, hvor foder fra en foderbeholder doseres til et trug, hvorfra flere grise kan spise efter behov, og hvor det med en føler detekteres at truget er 5 tomt, når grisene har spist hovedsagelig alt foderet i truget.The invention relates to a method for feeding pigs in paths where feed from a feed container is dosed into a trough from which more pigs can eat as needed and where it is detected with a sensor that the trough is empty when the pigs have eaten essentially all the feed in trough.
Ved en kendt metode til fodring af grise deles der med bestemte faste tidsintervaller tørfoder ud i truget, enten manuelt eller ved hjælp af en fodrings-10 automat. Den uddelte tørfodermængde er tilstrækkelig stor til, at alle grisenes sult kan stilles med en enkelt udfodring. Grisene æder tørfoderet direkte og kan efter behov drikke vand ved vandtappesteder i stien eller ved en separat drikkeventil i truget. Ved denne 15 fodringsmetode æder den enkelte gris i løbet af et kort tidsrum en større mængde foder i konkurrence med de øvrige grise i stien, og alle grisene har fri adgang til at drikke vand fra vandtappesteder og opblande yderligere vand i foderet.In a known method of feeding pigs, dry feed is dispensed into the trough at certain fixed intervals, either manually or by means of a feeding machine. The quantity of dry fodder distributed is sufficiently large that all the pigs' hunger can be satisfied with a single feeding. The pigs eat the dry feed directly and can, as needed, drink water at tap water points in the path or at a separate drinking valve in the trough. By this 15 feeding method, a single pig eats a greater amount of feed in competition with the other pigs in the path over a short period of time, and all the pigs have free access to drink water from tap water and mix up additional water in the feed.
20 Ved en anden kendt metode til fodring af grise, æder grisen foder og vand samtidig i form af vådfoder, som forudfremstilles ved at opblande en stor mængde tørfoder med en så stor mængde vand, at vådfoderet bliver pumpedygtigt, så at det i store portioner til de få 25 forudbestemte fodringstidspunkter kan pumpes hen til og ned i truget.20 In another known method of feeding pigs, the pig simultaneously eats feed and water in the form of wet feed, which is prepared by mixing a large amount of dry feed with such a large amount of water that the wet feed becomes pumpable, so that in large portions for the few 25 predetermined feeding times can be pumped up and down the trough.
En sådan metode kendes fra DE-A-32 18 438, hvor en føler detekterer at truget er tomt, når grisene har spist foderet i truget. Ved tomt trug sender føleren et 30 signal til en styreenhed, som registrerer den tid, det har taget for grisene at spise foderet. Ved det næste forudbestemte fodringstidspunkt justerer styreenheden dert uddoserede fodermængde i afhængighed af den tid, det tog at spise den sidst uddoserede fodermængde.Such a method is known from DE-A-32 18 438, where a sensor detects that the trough is empty after the pigs have eaten the feed in the trough. In the case of empty troughs, the sensor sends a signal to a control unit which records the time it has taken for the pigs to eat the feed. At the next predetermined feeding time, the control unit adjusts its dosed feed amount depending on the time it took to eat the last dosed feed amount.

2 væske i truget. Væsken tilføres ved hjælp af både en væskedoseringsenhed og af i truget anbragte drikkevandsventiler, som grisene kan påvirke for at opblande yderligere væske i foderet.2 liquid in the trough. The liquid is supplied by means of both a liquid dosing unit and by drinking water valves arranged in the trough, which the pigs can influence to mix further liquid in the feed.
5 Det er et formål for opfindelsen at anvise en fremgangsmåde til fodring af grise, som får grisene til at vokse hurtigere.It is an object of the invention to provide a method of feeding pigs which causes the pigs to grow faster.
Dette opnås med en fremgangsmåde, som ifølge opfindelsen er ejendommelig ved, at når føleren detekte-10 rer tomt trug doseres der automatisk både en ny tørfodermængde og en væskemængde, der i et forudbestemt forhold afpasses efter den doserede tørfodermængde, og at foderet ikke opblandes med yderligere væske.This is achieved by a method which according to the invention is characterized in that when the sensor detects empty trough, both a new quantity of dry feed and a quantity of liquid are automatically dosed, which in a predetermined ratio is adjusted to the metered dry feed quantity and that the feed is not mixed with additional fluid.
Som følge af at der doseres en ny portion frisk-15 blandet foder til truget, så snart grisene har spist den foregående portion op, har grisene hele tiden adgang til efter lyst- at æde friskblandet foder. I storstier, hvor der er væsentlig flere grise end ædepladser ved truget, medfører den frie adgang til foder, at gri-20 sene i et roligere tempo spiser hyppigere men mindre ad gangen, hvilket øger grisenes tilvækst. Ved hyppig ud-dosering af små fodermængder påvirkes grisenes nysgerrighed og de lokkes til fodertruget af bevægelserne og lydene fra doseringsmekanismen, og det har vist sig, at 25 grisene spiser lidt, når de alligevel er ved truget.As a result of dosing a new portion of fresh-mixed feed for the trough, as soon as the pigs have eaten up the previous portion, the pigs are always able to access freshly mixed feed according to their desire. In large paths, where there are significantly more pigs than eating places at the trough, the free access to feed causes the pigs to eat more frequently but less at a time, which increases the growth of the pigs. With frequent dosing of small amounts of feed the pigs' curiosity is affected and they are lured to the feeding trough by the movements and sounds of the dosing mechanism, and it has been found that the 25 pigs eat little when they are still in the trough.
Det er med opfindelsen erkendt, at grisenes tilvæksthastighed afhænger af forholdet mellem den indtagne væske- og tørstofmængde. Ved den traditionelle vådfodring, hvor det forblandede foder skal være pumpe-30 dygtigt, er væskemængden for stor i forhold til tørstofmængden, hvilket navnlig for smågrise fører til at grisenes sult delvis stilles af væskemængden i vådfoderet, hvilket mindsker grisenes tilvæksthastighed. I stier, hvor grisene har fri adgang til at drikke fra 35 vandtappesteder ved at opblande vand herfra i foderet, er der ligeledes tendens til at en del af sulten og ikke bare tørsten stilles ved drikning af vand.It is recognized by the invention that the growth rate of the pigs depends on the ratio of the amount of liquid and dry matter consumed. In the traditional wet feeding, where the premixed feed must be pumpable, the amount of liquid is too high in relation to the amount of dry matter, which in particular for piglets causes the pigs' hunger to be partially offset by the amount of liquid in the wet feed, which reduces the growth rate of the pigs. In paths where the pigs have free access to drink from 35 tap places by mixing water from them in the feed, there is also a tendency for a part of the hunger and not just the thirst to drink water.

3 ' Ved fremgangsmåden ifølge opfindelsen doseres foderet i form af tørfoder, hvilket giver mulighed for efter ønske at indstille forholdet mellem den doserede tørstofmænde og den doserede væskemængde, så at grisene 5 kan gives netop den mængde væske i forhold til tørstofmængden, som er optimal for tilvæksthastigheden.In the method according to the invention, the feed is dosed in the form of dry feed, which allows, if desired, to adjust the ratio of the dosed dry matter to the dosed liquid amount, so that the pigs 5 can be given exactly the amount of liquid in relation to the dry matter amount which is optimal for growth rate.
Ved en foretrukken fremgangsmåde afhænger det forudbestemte forhold mellem den doserede tørfoder- og væskemængde af grisenes vægt eller alder, hvilket mu-10 liggør, at mindre grise med henblik på at øge tilvæksten kan gives forholdsvis mere tørfoder i foderblandingen end større grise.In a preferred method, the predetermined ratio between the dosed dry feed and liquid amount depends on the weight or age of the pigs, which means that smaller pigs can be given relatively more dry feed in the feed mixture than larger pigs, in order to increase the growth.
Denne tilpasning af foderbladingens tørstofindhold til grisenes størrelse kan ved fravænningsgrise, 15 som har en vægt på omtrent 5 kg og en alder fra 21-28 dage, hensigtsmæssigt optimeres således, at forholdet mellem den doserede vægtmængde tørfoder og den doserede vægtmængde væske sættes til omtrent 1:1. Derefter øges det nævnte forhold fra omtrent 1:1 til omtrent 1:2,5 i 20 takt med at grisene vokser til fedesvin.This adjustment of the dry matter content of the feed leaf to the size of the pigs can be suitably optimized for weaning pigs 15 having a weight of about 5 kg and an age from 21-28 days, so that the ratio of the dosed weight amount of dry food to the dosed weight amount of liquid is set to about 1 : 1st Thereafter, said ratio increases from about 1: 1 to about 1: 2.5 as the pigs grow into fatty pigs.
Ved kun at dosere en lille mængde tørfoder pr. gang, såsom fra 100-200 g pr. uddosering,vil grisene i løbet af kort tid æde fodermængden, så at der i truget hele tiden vil være friskblandet foder, hvilket kan øge 25 grisenes ædelyst og vil mindske risikoen for maveproblemer som følge af forureninger i foderet i truget.By dosing only a small amount of dry food per day. once, such as from 100-200 g / ml. dosing, the pigs will in a short time eat the amount of feed, so that in the trough there will always be freshly mixed feed, which can increase the appetite of 25 pigs and will reduce the risk of stomach problems due to contaminants in the feed in the trough.
Opfindelsen vedrører også et apparat til brug ved udøvelse af ovennævnte fremgangsmåder, omfattende en foderbeholder med en doseringsenhed, som kan afleve-30 re foder til et understillet trug, hvorfra grisene kan spise, samt en fodermængdeføler, som kan afgive et signal, når truget er i det væsentlige tomt for foder. Ap-paratet er ejendommeligt ved en tørfoderdoseringsenhed for tilledning af tørfoder til truget, en væskedose-3 5 ringsenhed for tilledning af vand til truget, og en styreenhed indrettet til at aktivere tørfoder- og væ-The invention also relates to an apparatus for use in the above-mentioned methods, comprising a feed container with a dosage unit capable of delivering feed to a subordinate trough from which the pigs can eat, and a feed quantity sensor which can output a signal when the trough is essentially empty of feed. The apparatus is characterized by a dry feed dosing unit for supplying dry feed to the trough, a liquid dosage unit for supplying water to the trough, and a control unit adapted to activate dry feed and liquid feed.

4 ' skedoseringsenhederne, når fodermængdeføleren afgiver et trug-tomt signal til styreenheden. Den automatiske dosering og blanding af en fodermængde i truget, hver gang grisene har tømt truget, sikrer at grisene altid 5 har adgang til at spise friskblandet foder med et forudbestemt væskeindhold.The 4 'shed dosage units when the feed rate sensor outputs a trough empty signal to the controller. The automatic dosing and mixing of a feed quantity in the trough each time the pigs have emptied the trough ensures that the pigs always have access to eat freshly mixed feed with a predetermined liquid content.
Apparatet ifølge opfindelsen har hensigtsmæssigt en ovenover truget beliggende væskeoverrislingsledning, som strækker sig langs foderdoseringsenheden, så at den 10 doserede væskemængde vil fordele sig jævnt udover den doserede fodermængde for opblanding hermed. Den jævne fordeling af vandet udover tørfoderet er for opnåelse af en ensartet foderblanding over hele trugets længde navnlig vigtig, når der kun doseres en væskemængde sva-15 rende til tørfodermængden, idet væskemængden i dette tilfælde er så lille, at tørfoderet kan opsuge al væsken.Conveniently, the apparatus according to the invention has an above-the-wall fluid overflow line extending along the feed dosing unit so that the dosed amount of liquid will spread evenly over the dosed feed amount for mixing therewith. The even distribution of the water over the dry feed is particularly important in order to obtain a uniform feed mixture over the entire length of the trough when only a quantity of liquid equal to the dry feed quantity is dosed, since in this case the liquid quantity is so small that the dry feed can absorb all the liquid.
I en foretrukken udførelsesform er en styreenhed indstillet i afhængighed af grisenes vægt eller alder 20 til ved modtagelse af et aktiveringssignal fra fodermængdeføleren i truget at afgive styresignaler til foder- og væskedoseringsenhederne, så at den doserede vandmængde i forhold til den doserede fodermængde vokser med grisnes vægt eller alder.In a preferred embodiment, a control unit is set depending on the weight or age of the pigs, upon receiving an activation signal from the feed rate sensor in the trough, to output control signals to the feed and liquid dosing units so that the dosed water quantity relative to the dosed feed amount grows or age.
25 Et eksempel på en udførelsesform for et apparat ifølge opfindelsen beskrives herefter nærmere med henvisning til den meget skematiske tegning, hvor fig. 1 og 2 illustrerer henholdsvis et sidebillede og et ovenfra set billede af apparatet ifølge op-30 findelsen, og fig. 3 viser et tværsnit gennem apparatet efter linien III-III i fig. 1.An example of an embodiment of an apparatus according to the invention will now be described in more detail with reference to the very schematic drawing, in which fig. 1 and 2 illustrate, respectively, a side view and a top view of the apparatus according to the invention, and FIG. 3 shows a cross section through the apparatus along line III-III in FIG.

Beholderen 2 er opad åben for påfyldning af tørfoder undtagen i et midterafsnit, hvor en beskyttelseskappe 6 for en spin-10 delmotor 7 strækker sig op fra beholderen.3, two downwardly converging sidewalls 3 which pass 5 in an underlying dosing housing 4. The sidewalls 3 are supported by two end walls 5, which overlie and fix the trough relative to the container 2. The container 2 is open upwards for filling dry food except in a middle section, wherein a protective cap 6 for a spin-10 sub-motor 7 extends from the container.
Doseringshuset 4 og spindelmotoren 7 indgår i en doseringsenhed, som valgfrit kan styres til at dosere passende små tørfodermængder til truget 1.The metering housing 4 and the spindle motor 7 are included in a metering unit which can optionally be controlled to dispense appropriate small amounts of dry feed to the trough 1.
Et doseringskammer 8 er op- og nedadtil af-15 grænset af to tagformet vinkelbukkede pladestykker 9, 9', som af med mellemrum anbragte lodrette stivere 10 er fastholdt i en indbyrdes afstand, der stort set svarer til højden af doseringshuset 4. Pladestykkerne 9, 9' strækker sig over hele foderbeholderens længde og 20 afspærrer den fri passage fra beholderen 2 til truget 1. Det øvre pladestykke 9 og dermed hele kammeret er båret af tre stivere 11, som er således forbundet med spindelmotorens aksel, at spindelmotoren 7 ved aktivering vil forskyde hele kammeret 8 op- eller nedad i 25 forhold til foderbeholderen.A metering chamber 8 is bounded up and downward by two roof-shaped angular plate pieces 9, 9 ', which are spaced apart at intervals of vertical struts 10 which correspond substantially to the height of the metering housing 4. The plates 9, 9 'extends over the entire length of the feed container and 20 blocks the free passage from the container 2 to the trough 1. The upper plate piece 9 and thus the whole chamber is supported by three struts 11, which are so connected to the shaft of the spindle motor that the actuating motor 7 will actuate displacing the entire chamber 8 up or down in relation to the feed container.
Når det øvre pladestykke 9 under kammerets bevægelse opad løftes fri af doseringshusets sidevægge, sættes det indre af kammeret 8 i forbindelse med foderbeholderens tørfoder, som derfor vil strømme ind i 30 kammeret i en mængde, der afhænger af hvor højt kammeret 8 løftes op i beholderen 2.When the upper plate piece 9 is raised upwardly by the side walls of the dosing chamber during movement of the chamber, the interior of the chamber 8 is connected to the dry food of the feeding container, which will therefore flow into the chamber in an amount which depends on how high the chamber 8 is lifted into the container. 2nd
Når spindelmotoren 7 derefter bevæger kammeret 8 nedad, lukker det øvre pladestykke for passagen til foderbeholderen, hvorefter underkanten af det nedre 35 pladestykke 9' passerer ned gennem doseringshusets bundåbning 12, hvorved det nederste stykke af kamme-When the spindle motor 7 then moves the chamber 8 downwardly, the upper plate piece closes for passage to the feeding container, after which the lower edge of the lower plate piece 9 'passes down through the bottom opening 12 of the dosing housing, whereby the lower portion of the chamber.

6 rets åbne sider frilægges, så at det i kammeret værende foder glider ned i truget 1.The 6 open sides of the chamber are exposed so that the feed in the chamber slides down into the trough 1.
Et sprinklerrør 13 med mod truget vendte væskeafgangsåbninger strækker sig over hele doseringskam-5 merets længde og ligger således midt under dette, at det nedre pladestykke 9' leder foderet uden om røret, når kammeret tømmes. Sprinklerrøret er gennem en afspærringsventil 14, såsom en magnetventil, forbundet med en forsyningsledning for tryksat vand eller valle.A sprinkler tube 13 with liquid discharge port openings facing the trough extends over the entire length of the dosing chamber and lies in the middle thereof so that the lower plate piece 9 'guides the feed around the tube as the chamber is emptied. The sprinkler pipe is connected through a shut-off valve 14, such as a solenoid valve, to a supply line for pressurized water or whey.
10 En fodermængdeføler 15 omfatter et elektrisk ledende føleorgan 16, såspm en metalbolt, der ligger med et spillerum på fra 5 til 20 mm, fortrinsvis 15 mm, over et elektrisk ledende område 17 af trugets bund, og et elektrisk kredsløb 18 til detektering af den 15 elektriske modstand over føleorganet 16 og trugets bund. Kredsløbet 18 er gennem ledninger 19 og 20 forbundet med henholdsvis føleorganet og området 17, så at en spænding kan påtrykkes føleorganet. Kredsløbets signaludgang står gennem en ledning 21 i forbin-20 delse med en signalindgang i en styreenhed 22. Når truget er tomt for foder og den af kredsløbet detekterede modstand overskrider en forudbestemt tærskelværdi, skifter kredsløbets udgangssignal, så at et aktiveringssignal afgives til styreenheden 22. Føleorganet 25 16 og kredsløbet 18 er monteret i et rør 23 af isolerende materiale, såsom plast. Føleorganet rager ud gennem rørbunden, hvilket giver grisene adgang til at slikke området omkring føleorganet rent for foder.A feed quantity sensor 15 comprises an electrically conductive sensing means 16, such as a metal bolt, having a clearance of 5 to 20 mm, preferably 15 mm, over an electrically conductive region 17 of the bottom of the trough, and an electrical circuit 18 for detecting the 15 electrical resistance over the sensing means 16 and the bottom of the trough. Circuit 18 is connected through leads 19 and 20 to the sensing means and the region 17, respectively, so that a voltage can be applied to the sensing means. The signal output of the circuit is through a line 21 in connection with a signal input in a control unit 22. When the trough is empty of feed and the resistance detected by the circuit exceeds a predetermined threshold value, the output of the circuit switches so that an activation signal is output to the control unit 22. Sensor 25 16 and circuit 18 are mounted in a tube 23 of insulating material such as plastic. The sensor protrudes through the bottom of the tube, giving the pigs access to lick the area around the sensor free of feed.
Styreenheden 22 har to signaludgange, som gen-30 nem ledninger 25, 26 er forbundet med henholdsvis spindelmotoren 7 og afspærringsventilen 14.
