Definitions

  • the invention relates to a method of feeding animals, wherein the animals are fed ad lib. when they have a weight which is below a given value, while they are fed restrictively when the weight passes the given value.
  • the invention relates to a feed dosing system comprising a plurality of feed dosing units which receive feed via one or more rotatable pipes.
  • the invention relates to use of the method and of the feed dosing system.
  • feed bowls or long cribs where the feed bowls may be used for dry feed as well as aqueous feed, while long cribs are used for aqueous feed, cf., however, the following.
  • a feed dosing system having a plurality of feed bowls is known from WO 2006/097103 A1.
  • the feed bowls are connected to feed dispensers so that feed is transferred from the feed dispensers via vertically extending pipes.
  • an object of the invention is to provide a method and a feed dosing system, in which effective feeding of pigs may be carried out in the two phases, where, as mentioned, feed is given ad lib. in the first phase, while feed is given restrictively in the second phase.
  • the object of the invention is achieved by a method of the type defined in the introductory portion of claim 1 and by a feed dosing system of the type defined in the introductory portion of claim 4, which are respectively characterized in that, during the ad lib.
  • the animals are given feed from one or more feed bowls and are given feed in a limited amount from one or more long cribs, while the animals, when they are fed restrictively, are given feed from one or more feed bowls and one or more long cribs, and in that the feed dosing units are connected at the bottom with a plurality of feed bowls via vertically extending, thick pipes and are connected with a plurality of long cribs via vertically extending, thin and inclined pipes.
  • the given weight is adapted as to whether it is female or male pigs which are fed.
  • An expedient structure of the feed dosing system is, as stated in claim 5, that the feed bowls and the long cribs are configured as a common long trough, which provides the advantage that cleaning is easier to carry out, and that the distribution of aqueous feed may be performed evenly in the long trough.
  • a distributor unit is connected between the inclined pipes and the long trough, said distributor unit having at least two compartments which are separated by a partition wall, each of said compartments having one inlet and two outlets, said two outlets extending obliquely downwards toward the long trough at their respective sides relative to the axis of symmetry of the inlet, and, as stated in claim 7, that the inlet leads into a box which merges into two boxes, which extend obliquely at each side relative to the box and are ter- minated by the outlets.
  • compartments in the feed dosing system are configured as a circular pipe in which a helical partition wall is arranged, which reduces the number of corner joints inside the distributor unit, which in turn facilitates cleaning, as the inner side of the pipe itself and the partition wall then serve as slide faces.
  • the feed dosing units are formed by a rotatable pipe which is provided with holes along its longitudinal axis, said holes being disposed axially and radially offset relative to each other.
  • the feed is advanced in the rotatable pipe via a worm conveyor, and that at least one collection magazine is arranged below the rotatable pipe at a plurality of the holes of the rotatable pipe, said collection magazine being adapted to be filled with feed during the advancing movement of the worm conveyor.
  • the invention also relates to use. This use is defined in claim 20.

  • fig. 2 shows parts of a feed dosing system according to the invention
  • fig. 3 shows the feed dosing system of fig. 2 with a distributor unit incorporated in it
  • fig. 4 shows the distributor unit of fig. 3 in greater detail
  • fig. 5 shows the distributor unit of fig. 4 seen obliquely from above
  • fig. 6 shows an alternative dosing system having a feed dosing unit formed by a rotatable pipe
  • figs. 7A/7B show the rotatable pipe of fig. 6 in various working posi- tions
  • fig. 8 shows another embodiment of the rotatable pipe of fig. 6,
  • fig. 9 shows the rotatable pipe of fig. 8 in another embodiment
  • fig. 10 shows structural elements in the coupling of the rotatable pipes of figs. 6 - 9.
  • Fig. 1 shows two curves 1 , 5 in an X 1 Y system of coordinates, where a weight (for a pig) is indicated along the X- axis, while the Y-axis indicates feed amount expressed in feed strength or nutritive content per weight unit of a pig.
  • Curve 1 is a typical feed curve used for wet feeding, while curve 5 shows a typical course in the use of ad lib. feed dispensers.
  • the curve 1 consists of a rising (here rectilinear) section 2 and a constant section 3, where the transition between the rising section 2 and the con- stant section 3 is designated 4.
  • the curve 1 illustrates two phases of a feeding course, in particular for wet feeding of pigs, where phase 1 is represented by the rising section 2 on the curve 1 and is tantamount to the pigs being allowed to eat wet feed ad lib. in their first period of growth, which ends at the point 4 on the curve where the pigs have a weight of about 62 kg. Then, restrictive feeding is adopted, as shown by the constant section 3.
  • a more "aggressive" feeding which, as mentioned, is used in particular when feeding in connection with ad lib. feed dispensers supplied with dry feed, is illustrated by the curve 5, where it will be seen that the first phase corresponding to the curve section 5 changes to restrictive feeding already at the point 4A when the pigs have a weight of about 43 kg. The time of the transition to the restrictive feeding is thus accelerated.
  • 9 and 9A designate feed dosing units known per se, which receive feed from above via a supply pipe 10. From the feed dosing unit 9, a vertically extending, thick pipe 11 and two inclined pipes 12, 13 are connected downwardly.
  • the inclined pipes 12, 13 are connected in a wall 14, cf. also fig. 2, with a distributor unit 18, whose mode of operation will be explained more fully in connection with fig. 4 and fig. 5.
  • the feed dosing unit 9A is connected with a vertically extending, thin pipe 19 having the same dimensions as the pipes 12A, 13A.
  • a through-going long trough with areas 15, 16 is arranged, where the area 15 is disposed below the thick pipe 11 which is terminated by a nipple 11A.
  • the feed dosing unit 9 with the thick pipe 11 , the nipple 11A and the area 15 corresponds to a feed bowl which is intended for ad lib. feeding, while the same feed dosing unit 9 with the inclined pipes 12, 13 and the area 16 corresponds to a long crib which is preferably intended for restrictive feeding.
  • the feed dosing unit 9A is terminated by a thin pipe 19 which has the same function as the inclined pipes 12A and 13A, and is thus used in connection with restrictive feeding.
  • the feed dosing system is set such that feed is constantly supplied to the area 15 of the long trough via the thick pipe 11.
  • the feed dosing system is set such that the areas 16, 16A are supplied with a limited amount of feed within 24 hours, which is optimum for pigs with precisely the weight they have. Since the areas 16, 16A are elongated, it is ensured that the pigs do not "fight" about the feed, since this would mean that the smallest pigs would get too little feed and thus a smaller growth than desirable, while the bigger pigs would get a too strong growth because of a certain overfeeding.
  • a distributor unit 18 has an inlet 20 and two outlets 27, 28.
  • the inlet 20 leads into a box 2OA, which merges into two boxes 27A, 28A which are angularly offset relative to each other and are terminated by the two outlets 27, 28.
  • a partition wall 21 which divides the distributor unit into two compartments, is arranged in the boxes between the inlet 20 and the outlets 27, 28.
  • Slide faces 22, 23 are provided along the outer side edges 29, 30 of the partition wall 21 perpendicularly to these side edges, where the free edge 22A of the slide face 22 is oriented oppositely to the free edge 23A of the slide face 23.
  • the partition wall ends at a point 31 , where also the slide faces 22, 23 meet and continue in their respective boxes 27A, 28A toward the outlets 27, 28, which are disposed angularly offset at each side of the axis of symmetry of the box 22A which extends through the point 31.
  • the slide faces are shown to be composed of a straight section in the box 22A, which, in the boxes 27A, 28A, merges into a curved section or a section with a bend (not shown) which is terminated by a recti- linear section.
  • the above structure of the distributor unit may be configured as a pipe, where a helical partition wall is arranged centrally in the pipe. In this case, too, the pipe will have one inlet and two outlets, as the pipe is terminated downwardly by two pipes.
  • the dosing system here consists of a feed bowl 15 which is con- nected at each side with a long crib 6 and 16, respectively, although the number of feed bowls and long cribs may be varied.
  • Feed for the dosing system is supplied via a reservoir (not shown) to a pipe 32, from which it is conveyed through a rotatable pipe 33 by means of a worm conveyor (not shown), as will be explained later.
  • 3A, 6A designate two feed portions, and, as will be seen, there are several feed portions below the feed bowl 15 and the long crib 16.
  • the feed portions 3A, 6A are uniform in terms of weight, since feed portions of non-uniform weight will result in a non-uniform amount of feed to the animals, so that the "strongest” animals” will get too much feed, while the “weakest” animals will get too little feed.
  • the rotatable pipe 33 is shown with two openings, which are designated 34 and 35.
  • the opening 35 is disposed above the thick pipe 11 or the thin pipe 19 (not shown) in fig. 2, W
  • the opening 35 is disposed above the long crib 16.
  • the openings 34 may be disposed above the thick pipe or the thin pipe, so that feed cannot be supplied to the thick pipes 11 and the thin pipes 19, while the openings 35 are disposed above the long cribs 16, so that feed is just supplied to the long cribs 16 (fig. 7A).
  • the openings 34 may be disposed above the thick pipe or thin pipe, so that feed may be supplied to the thick pipes 11 and the thin pipes 19, while the openings 35 are disposed so that feed cannot be supplied to the long cribs 16 (fig. 7B).
  • the openings 34 may be disposed above the thick pipe or the thin pipe, so that feed may be supplied to both the thick pipes 11 and the thin pipes 19 as well as the long cribs 16 (not shown).
  • Fig. 8 shows an alternative embodiment of the structure of the rotatable pipe 33, in whose interior a worm conveyor 37 extends.
  • Three collection magazines are here designated 36, 36A, 36B, which are disposed on top of the rotatable pipe 33 after this has been emptied of feed through areas, which are designated 38, cf. the schematically shown holes which are connected with the feed bowls and the long cribs.
  • the collection magazines are intended to ensure that the entire pipe 33 is filled with a uniform amount of feed before it is emptied, as they are dimensioned such that the collection magazine 36 has a larger volume than the collection magazine 36A, which in turn has a larger volume than the collection magazine 36B.
  • the collection magazines with suitable volume dimensioning are arranged longitudinally of the rotatable pipe, these will be able to receive a suitable amount of feed and thereby compensate for the varying friction.
  • the rotatable pipe 33 In a starting position, the rotatable pipe 33 is rotated so that the collection magazines 36, 36A, 36B face downwards, while the holes in the areas 38 face upwards.
  • the collection magazines 36, 36A, 36B When feed is now advanced by the worm conveyor 37, the collection magazines 36, 36A, 36B will be filled with an amount, which is commensurate with the rotatable pipe 33 receiving the same amount of feed at the locations concerned as at the inlet to the rotatable pipe 33.
  • the rotatable pipe 33 is rotated as shown in fig. 8, following which feed is supplied to the feed bowls and the long cribs in equal, metered amounts, as shown in fig. 6 at the reference numerals 3A, 6A.
  • the collection maga- zines are replaced by a through-going trough 39, which, production-wise, is easier to manufacture than several collection magazines.
  • a trough has been found to be able to provide sufficient and equally metered amounts of feed to the feed bowls and the long cribs.
  • the dosing system 40 face upwards, i.e. that the dosing system assumes a position in which it is ready to be filled with feed by the advancing movement of the worm conveyor 37.
  • fig. 10 shows schematically how the rotatable pipe 33 and the worm conveyor 37 may be coupled together.
  • 41 designates a gear wheel, which may be driven by a motor (not shown) clockwise and counterclockwise.
  • Two bearings 42, 44 are connected with an attachment part 45 for the worm conveyor 37, which, when the motor (not shown) rotates clockwise, will drive the worm conveyor forwards.
  • the rotatable pipe 33 (not shown) is mounted on another attachment part 43, so that it may be rotated to assume two positions, where one position is that the rotatable pipe has the holes facing downwards so that the rotatable pipe is emptied, while, in the other position, it has the holes facing upwards so that the rotatable pipe may be filled, as explained above.

Abstract

L'invention concerne un procédé pour l'alimentation d'animaux, de préférence des cochons, selon lequel les aliments sont disposés de sorte que les cochons puissent se nourrir à discrétion lorsque leur poids est inférieur à une certaine valeur donnée, alors qu'ils sont nourris de façon restrictive lorsque leur poids est supérieur à un poids donné. L'invention concerne un procédé et un système de dosage des aliments, ledit système comprenant plusieurs unités de dosage des aliments (9, 9A) reliées à plusieurs récipients pour les aliments (15) et plusieurs mangeoires oblongues (16), lesdits récipients pour les aliments et lesdites mangeoires oblongues formant une auge commune oblongue (15, 16), composée de tubes inclinés (12, 13, 12A, 13A) et de tubes s'étendant verticalement (11, 19) reliés longitudinalement à l'auge oblongue. Les emplacements dans lesquels les tubes épais s'étendant verticalement (11) sont reliés à l'auge oblongue sont utilisés pour l'alimentation à discrétion, alors que les emplacements, dans lesquels les tubes fins s'étendant verticalement (19) et en position inclinée (12, 13, 12A, 13A) sont reliés à l'auge oblongue, sont utilisés pour l'alimentation rationnée. Cela permet de garantir que tous les cochons, même les 'faibles', reçoivent une nourriture suffisante au cours de l'alimentation rationnée, du fait que les bagarres entre cochons en raison de l'espace restreint pour accéder à la nourriture sont évitées. Pour une distribution uniforme des aliments secs dans les mangeoires oblongues, des unités de distribution (18) sont reliées entre les tubes inclinés et l'auge oblongue, lesdites unités de distribution dans un premier mode de réalisation étant dotées de deux compartiments séparés par une cloison (21), et dans d'autres modes de réalisation, configurées sous forme de tubes pivotants pourvus d'orifices, et en option, des dispositifs de collecte sont placés dans certains des orifices.
