Abstract

FIELD: agriculture.

SUBSTANCE: feeder comprises feed duct, feeding pan and grid. The feeding pan bottom is protected by a rubber insertion 4-6 mm thick to prevent damage of the poultry beak. The grid is fitted by an above set split ring with beams to separate the grid into additional sections. The split ring is fitted with a catch on the one side, and a hinge on the other side to form a solid ring when connected.

EFFECT: restraining movement of poultry neck during feeding, reducing scattering of feeds and poultry death.

Description

The invention relates to industrial poultry, in particular to feeders for poultry.

The purpose of the invention is the restriction of the movement of the head of the bird during feed consumption, the reduction of placer feed and the death of chickens.

Known bunker feeder, commercially available with cell batteries such as BGO-140, which has a removable extension. Thanks to the removable extension, it is possible to feed the repair young from one feeder from 1 to 140 days without installing additional trays and feeders. The disadvantage of this feeder is that it is used only in single-tier cell batteries, and its large metal consumption [1].

Known feeder for poultry, including a feed line to which a hopper is connected, vertically moving and having a fence. Under the hopper there is a feed bowl having a cone-shaped base. The disadvantage of this feeder is that it is not used in commercially available cell batteries, it is metal-intensive, has a “screw-nut” control device, which, under conditions of high humidity in the house, quickly corrodes and fails [2].

The drawing shows a feeder for feeding chickens, General view.

The form and material of the base of the feeder, as well as devices restricting the movement of the head of the bird during feed consumption, are of great importance for the feeding of the bird, its quantitative and qualitative indicators during the growing process.

When using feeders, there is a spread and significant loss of feed. The use of feeders with a round convex shape of the base in combination with an additional rubber coating of the base provides the smallest scattering and high gain in live weight with minimal feed costs.

In the last growing period, as a result of frequent blows of the beak to the metal bottom of the feeder, the number of birds with changes in the shape of the beak significantly increases (erasing horn covers, curving, pecking, etc.). Beak defects are most commonly found in birds with high live weight.

Up to 5 days of age, chickens are fed from pallets and then bunker feeders are used. To accustom chickens to the noise of working mechanisms, they first turn on the feeders without filling them with food. After 7 days, chickens are already fed from hopper feeders supplied with commercially available cell batteries. Falling through the grate that covers the feed tray with feed, the chickens are driven into the feed line, the next ones fill the feed tray itself. When the feed line is turned on, the feed falls asleep to the chickens in the feed compartment of the feeder, as not all chickens are able to independently get out of the tray, and they die. The poultry house is not able to release all the chicks from the chickens before distributing the feed. With the improvement of the hopper feeder, an additional split ring with a loop is installed on the grating with dividing rods. On an additional detachable ring, beams are fixedly fixed, which divide the cells of the lattice of the hopper feeder into segments. The formed segments in size do not allow chickens to fall into the feed tray. With an increase in body size, when the chicken no longer falls into the feed tray, the split ring is removed and used for the next landing of the chickens.

Serially produced metal bunker and groove feeders do not ensure bird safety. When feeding, significant changes in the shape of the beak are observed: the abrasion of the horn covers, their bending or pecking, which occurs because the bird strikes the bottom of the feeder with great force. Injury to the beak affects the increase in live weight and the safety of the livestock. Insert a raw rubber insert from 4 to 6 mm thick into the feeder, grooved or bunker, so that the entire surface of the feeder (on three sides) is protected. Rubber of lesser or greater thickness is not cost-effective to use.

The hopper feeder contains a feed pipe 1, through which feed is fed to the feed tray 2, which is closed by a grate 3. An additional split ring 4 contains beams 5 that divide the grate 3 into additional segments that prevent chicks from falling into the feed tray 2, the bottom of the feed tray is closed by a liner 6 from rubber 4-6 mm thick to prevent injury to the bird's beak.

An additional split ring 4 at its ends has a latch 7 on one side and a loop 8 on the other, which form a continuous ring when they are connected and secured to the grate 3.

Hopper feeder works as follows.

The feed through the feed line 1 enters the feed tray 2 and fills it, on top of the feed tray 2 is covered with a grid 3, the dimensions of which are calculated on the size of the head of an adult bird, regardless of the cross used.

A detachable ring 4 with beams 5 is put on top of the grate 3 to divide the grating into additional segments, the detachable ring having a latch 7 on one side and a loop 8 on the other for forming a continuous ring when connected.

An additional split ring 4 is put on top of the grill 3 and secured to it. Rays 5 constitute an inextricable connection of an additional split ring 4, which divide the lattice 3 into additional segments. The sizes of the segments that are formed between the grill 3 and the beams 5 prevent the chicks from falling into the feed tray 2.

The use of a raw rubber liner for feeding the birds showed that the number of birds with changes in the shape of the beak decreased by 2%, the safety increased by 2.8%, the life of the feeder increased by 30%.

Tests of the bunker feeder showed that the live weight of the bird at 40 days of age was 2269 ± -4.51 g in 1997, ± 11.4 g in the control. The cost of feed per 1 kg of increase in live weight - 2.92 kg at 2.88 kg - in the control. The safety of the livestock was 98.1%, with 96.5 in the control.

Loss of feed from spilling over 40 days - 1.64% at 3.10% in the control.

The number of birds with changes in the shape of the beak is 4.7%, while 10.2% of the total number is in the control.

Studies have shown that for eight days with three to four times feeding, up to 10% of chickens in the same cage with an unimproved feeder were injured and died. Losses of birds amounted to 3,000 goals. in one landing.
