MGH Agricultural Technologies is proud to be the global leader in Automated Nesting Systems for the Turkeys Breeders Industry.
Our systems are installed and used in hundreds of farms across five continents. Every day, millions of eggs reach our customers cleaner, faster, and cheaper. MGH sets the standards for automated nesting systems around the globe.
MGH system offers two types of nesting systems: wide and regular.
THE ADVANTAGES OF THE MGH AUTOMATED NESTING SYSTEM
The Conveyor Belt
Preparing for the hen placement
- Open the nest open
- Make sure the traps are at working position or upper position (according to the breeder’s decision)
- Place a pile of straw / shavings in each nest.
- Flap clip up with the flap retainer (if your training includes straw in the nests).
* All preparations must be completed before the hens are placed
From hen placement to the first egg
- Activate the nests 1 – 2 times a day.
- Minimize the entries to the barn, avoid staying at the front of the barn.
From the first egg to the third day
- Enter the barn a few times a day to collect floor eggs and place them in the nests
* If you frequently find eggs on the same place of the floor, there must be a reason for it. Identify the problem and solve it. The hens acquire their laying habits fast, so resolving the problematic spots needs to be done ASAP.
From the fourth day to 30% of production
- On the 4th day, remove all the eggs from nests. From this stage on, the eggs will be collected for incubation.
- On the 4th day, collect the eggs three times a day by activating the nests manually. Place the eggs on belt by hand.
- Add 1-2 collections every day according to the increase in production.
- When no more straw is left in the nests, release the flap from the flap retainer.
- At 20% of production, gradually lower the traps to a working position (do it within 3-4 days).
From 30% to peak production
- Close the nests at night.
- Set the system to automatic mode. The nests should be closed for five minutes.
- The collection cycle (the time interval between collections) should be at least one hour.
- Avoid unnecessary activity near the nests until the hens reach peak laying.
Training the birds should be done carefully and gradually by means of a stepped process.
- Collection intervals – When the hens reach peak daily production, activate the nests every hour. The interval between collections should be at least one hour. The morning and afternoon intervals can be longer than one hour.
- In order to increase the percentage of hen replacement in the nests during collection, the nest should be closed for five minutes.
- It is important to synchronize the collection of floor eggs during the automatic collection. The worker should walk along the ramp and remove the hens from the ramp.
One of the advantages of the MGH Egg Collection System is its durability. On many of our customers’ farm’s we see systems that have been working for 25 years. A system with such a long life span needs to be well maintained. On our many visits to clients, in Israel and all over the world we have noticed a common phenomenon of neglect to the pneumatic systems particularly with regard to the pistons.
The main reasons for this are:
- In contrast to other parts like the spring, the trap, the mat and more,
where the difference between a damaged part and a functioning part is
clear, the piston is a kind of “closed box”. The parts are concealed inside
and the deterioration in performance quality is slow.
- Compared to the maintenance of the remainder of the system, which is
characterized by quickly and simply replacing parts, maintaining the
pistons requires a high technical competence, a “clean” technical work
area and appropriate tools.
According to MGH performance criteria a “non-functioning nest” means 5 hens without a place to lay eggs. In other words: every nest is important. The problem becomes critical
in the case of the pistons because each piston is responsible for operating 32 nests. Therefore the importance of a proper functioning of the pistons is critical !!!
The purpose of this document is to give you, dear customers, tools and recommendations with respect to the pistons and the pneumatic system, information on issues such as: fault detection and characterization; preventative maintenance; planning and operating correctly and more. We hope that this document will enable the desired quantum leap in quality.
Tests and fine-tuning:
- Fine-tuning the pistons:
- Because the piston fork is fixed, the piston rod tends to turn and therefore the piston length changes. The result: Loss of adjustment of the doors.
- One must tighten the nut under the piston fork towards the fork itself in order to prevent the fork turning.
- If the doors associated with a particular piston are not aligned with the rest of the pistons then one needs to “close” or “open” the piston fork and in so doing, to adjust the doors to the desired alignment. Then you need to adjust the doors so that in the position of “open nest” all the flaps are in contact with the cable.
- The rule of thumb for the adjustment of the piston fork is: there should remain a margin of 3mm until the beginning of the thread on the piston rod after tightening the nut.
- Testing for leaks.
Check systematically that there are no air leaks in the system:
- Around the piston rod.
- Disconnect the pipes connected to the piston, one by one in order to find leaks in the pistons.
- Check the air connectors and the pipes along the length of the nests (in the case of damage to the general pipe system.)
- Pistons of 100 mm diameter will “run” 30 regular nests (modules of 5) or 32 wide nests (modules of 4). There is a high likelihood that the pistons will not have enough power to push a larger amount of nests.
- Pistons of 80 mm diameter (if there are still any) will “run” a maximum of 20 nests. In general it’s recommended to work only with pistons of 100mm diameter.
- It is recommended to initiate replacement of the gaskets once every 10 years in order to ensure proper operation of the pistons.
- While replacing the gasket, check to see that the piston’s pipe is whole and that the piston rod is not scratched.
- Before inserting the “sliding seal” (the seal on the piston rod) check that the piston rod is not worn.
- Record the replacement dates on the piston after replacing the piston seals in a way that won’t be erased over the years.
- A number of coops should not be operated concurrently as this reduces pressure in the system.
Water in the compressor: Water in the compressed air causes damage to the pneumatic system and accelerates deterioration.
- Drain the compressor tank a number of times a day (it is recommended to do this automatically using a tap with a timer.)
- Make sure that a water drainage unit is installed at the beginning of the lines.
- Install greasers in order to lubricate the valves and the other parts of the system.
- Install an air dryer.
- In the compressor: 8 -10 atmospheres.
- In the pressure regulator at the beginning of the line: 8 atmospheres.
- Make sure that appropriate nozzles are installed at inputs to the piston, including filters before and after the nozzles (to prevent blockages). Pistons of 100 mm diameter – nozzles 18 mm and pistons of 80 mm diameter – nozzles 14 mm.
