Understanding What Really Matters in Automatic Calf Feeding Systems
Recent scientific studies have demonstrated that by treating calves to an effective feeding programme as early as in the first weeks of their life, considerably higher milk production can be expected (so-called metabolic programming).
Many small rations - their quantity, composition, and temperature matched with age, race, sex, and state of health of the respective calves - are the optimum preconditions to deploy the calves' genetic potential to their fullest extent.
However, every farmer is faced with the issue of how to put this into everyday practice, despite a busy work schedule. Luckily the practice is (virtually) as easy as the theory when assisted by automatic feeding systems.
·         Improved quality of life for yourself
·         Healthy calves reared in groups
·         Reduced costs, improved returns
·         Safety and reliability
Here's how it works:
·         The calf is identified electronically.
·         The milk diet is freshly prepared and pumped to the teat in a matter of seconds.
·         The tubing to the teat is rinsed after every visit, plus an automatic wash cycle is run twice a day.
·         An anti-pirate valve prevents others from stealing a calf's milk ration, so every single calf gets the quantity of milk it needs.
·         An added second mixer bowl allows simultaneous feeding of two calves.
Improved Quality of Life for Yourself
Adapt calf feeding to the way you live your life! If you are one of those who wish to alleviate the burden of the calf feeding routine and have more time for the important things in life, then read on.
Gain Time
·         Your H&L 100 feeds your calves; all you do is check if the apparatus and the calves are fine.
·         Teaching the calves how to use it does not take long, and they drink on their own after only two visits in most cases. For the H&L 100 sends the milk diet to the teat immediately; this is why the calves — including the smaller ones — get their ration in a matter of seconds.
·         Transponders are identified automatically.
Enjoy More Flexibility for an Improved Quality of Life
·         Look after your calves on your own time rather than allowing the calves to rule how you organise your day. There is usually so much else to do, so many things to attend to, in particular in the morning and in the evening, that conflicts with normal feeding hours. This includes milking and feeding the cows, preparing breakfast for the family, taking the children to school, etc.
Work Easier
·         Your back will be grateful — no more strenuous bucket carrying! All you do is put milk replacer powder into the big reservoir or whole milk into the appropriate tank.
·         Thanks to the automatic wash cycle, you simply check the proper outcome of the washing.
Rely on Easy-to-use Support Tools
·         Drinking quantities, times of day the calves called, frequency of visits, drinking speed, and body weight are all presented in easily readable information screens. The data help you identify calves early that may require specific attention, and assist in taking appropriate action.
·         The calves that wear a life-long ear tag will be recognized automatically when they call for the first time at the H&L 100 and added to any approppriate data lists.
Hygiene Stations
Optimum hygiene
Tube cleaning including the teat
All tube systems used to have deposits of contaminated milk because they had not been cleaned often enough or thoroughly enough. For the first time the new Hygiene Station can automatically flush out and clean the whole milk pipeline right through to the teat after ach feed. This will reduce a calf’s exposure to bacteria, improve the health of the calves and save on manual cleaning.
         Always have a clean teat
The teat on a feeding station has the potential to spread germs. In the new Hygiene Station the teat is cleaned after every visit. Germ contamination on the teat drops by an average of 80%!
         Cleaned mucus bowl
Each calf produces mucus when drinking. With the hygiene system this is collected together with the cleaning water of the teat in a mucus bowl and washed away after each feeding process. This means that the floor area within the feeding station stays clean and dry.
         Cleaning at 65° C/150°
Temperature is a key factor when cleaning, so we can clean both the mixing jar and all hoses to the nipple at up to 65° C/150° F.
      Healthy nutrition
      Natural drinking approach
The teat at the feeding station is positioned so that it slants downwards in a similar way to the teats on the suckler cow.  This encourages the natural drinking position of the calf. When the head is stretched, this encourages the natural re? ex of the oesophageal groove and reduces the risk of milk passing into the rumen
        LED lit teat
Practice has shown that the calves can orientate better when the teat is illuminated. This increases the intake of milk during the night and during the day the stable is also calmer because the feeding process is evenly distributed over 24 hours
        Individual mixtures
Many feeding systems work with a central milk supply from which all calves get the same milk. This presents a problem: Modern feeding programmes (e.g. the metabolic programming) require a higher CMR concentration at the start of rearing (e.g. 160 g/l) to give a metabolic pulse. In the drinking phase however, a lower concentration is needed (120 g/l). Our individual animal feeding is the basic requirement for these modern feeding strategies.          
         Always freshly mixed
The central milk supply of conventional machines has another disadvantage: At 40° C/104° F, the germ content in milk doubles every 20 minutes. With the HL100 no milk residues are left in the system and the milk is freshly mixed for each calf, no matter how many calves you have!
      Straightforward work
      Calves teach themselves
As soon as a calf lifts the teat, a small amount of milk flows into its mouth. This stimulates the calf's initial drinking impulse; manual learning is necessary in only exceptional cases. IMPORTANT: When the calves are learning to use the feeder we take speci­fic care to ensure that milk is not entirely pumped into the mouth as this can easily result in fluid entering the rumen
         Can be tilted to clean
Many stations are installed directly in the pens. The Hygiene Station can be tipped forward at a 90° angle so that manure can be removed and the whole area can easily be mucked out with the use of a tractor.
         Quick-release teat fastener
The nipple can easily be changed with a quick-release handle.
         Convenient operation
All components can be reached at a comfortable working height. This eases control. Parts that are relevant for maintenance are highlighted in yellow. The design of the station also makes it possible to place the station in the outdoor climate stable, because all parts are securely frostproof packaged.
Healthy Calves
Nature is our model. It shows us how calf rearing should take place. The calf suckles its mother's udder whenever and as long as it likes. Learn how your calves, too, will be satisfied and healthy and will develop outstandingly.
Enjoy Calm and Compliant Calves
·         Since the H&L 100 does not restrict feeding to certain times of day, calves can come and drink at any time. They will not see a nurse in you and, therefore, will remain calm when people enter the barn.
·         Younger and weaker calves have all the time they need to be awarded their full ration. The anti-pirate valve ensures that stronger calves will not steal their milk. You'll see the result: very homogeneous groups of calves!
Have the Rations Prepared as the Animals Like it
·         The H&L 100 prepares a fresh milk diet any time a calf calls: the quantity, composition, and temperature are exactly what they should be.
·         The calf is given the allocated ration in the form of several, small portions. This imitates its natural behaviour and supports healthy digestion.
Work with Flexible Feeding Programmes
·         Feeding depends on the calf's age, body weight, and breed. Five different feeding programmes as well as individual settings for every single calf are available to enable maximum flexibility.
·         Feeding various calves at the same feeder stall, but according to different programmes (e.g., milk replacer diet and whole milk diet) is possible because every ration is freshly prepared when the calf calls.
·         The H&L 100 is very gentle as it prepares the calves' transition to concentrate and forage feed. At the end of the milk diet stage, it reduces the allocated quantity in small steps of 0.2 litres (½ lb) per day, thereby stimulating the development of the forestomach system.
Achieve Optimum Calf Monitoring
·         Data lists provide a quick overview of your calves' wellbeing. Animals that may require attention appear on specific alarm lists.
·         Particularly valuable information is compiled by the animal weigh scales in the feeder stalls. The early identification of weight loss enables the singling-out of calves suffering from diarrhoea. In turn, this allows treatment before they develop a serious disease.
Administer Feed Additives Effectively and Individually
·         Minimal doses of acids (or other additives) can be added to the milk diet in order to stabilise the gastro-intestinal system.
·         Medicines can be added to the milk diet of sick calves, or electrolytes and water can be supplied with a specific dietetic programme.
·         Two dosing units are available for maximum flexibility. Choose between two powder dosers or one doser for powdered and one for liquid additives.
Accept Only the Best When it Comes to Hygiene
·         After every visit, the mixer bowl and the tubing to the teat are rinsed with clear water. No milk residues will remain in the system.
·         The H&L 100 starts a wash cycle automatically at least twice a day (more frequently with a whole milk diet).
·         The outer surfaces of the H&L 100 and the feeder stall allow for easy cleaning with water.
Reduced Costs, Improved Returns
Successful calf rearing is the cornerstone of future high performance in dairy and veal production. However, rearing requires early expenditure too. If you are one of those who want to make investments for the future of your business and still cut expenses, then read on!
Save on Feed Cost
·         Controlled feeding and early weaning enable you to save up to 15% on feed, as compared to bucket feeding.
·         Milk replacer consumption can be reduced, mainly towards the end of the milk diet stage, by adjusting the replacer concentration in the diet.
·         As a means of managing rearing costs, the H&L 100 provides listings of whole milk and milk replacer intake for every calf.
·         Cost cutting potentials can also be leveraged by relying on every calf's individual development and weaning them according to their body weight gain. This is where an electronic animal weigh scale is useful.
Safety and Reliability
The feeding equipment is just like any employee in your operation - you want it to be reliable. The H&L 100 has been developed specifically to feed your calves 24 hours a day, 365 days a year.
Rely on High-quality Components
·         All milk-carrying components are made of high quality stainless steel or food-grade materials.
·         The milk replacer reservoir, including its powerful auger, is made to sustain high loads and strains. Therefore, it will correctly dose almost all milk replacer powders.
·         The whole milk system is very effective thanks to a heat exchanger coil that is 7.5 m (25 ft) long
·         The design of the electronics has been kept simple and reliable, in order for it not to be susceptible to the harsh environment of an agricultural operation.
Get Ready to Work Whatever the Weather
·         The H&L 100 is a particularly good choice for housing calves outdoors.
·         It is equipped with an anti-freeze programme that runs automatically as soon as there is a risk of frost.
·         You can wash the outer surfaces of the automatic feeder with water: all sensitive components are water spray proof.
Keep Intruders out
·         Two large doors protect the critical compartment in which the mixer bowls are installed. This keeps flies away from the milk, thereby also avoiding plugged milk feeding lines.
·         The doors can be locked so children cannot get harmed or injured.
Be on the Safe Side with Easy Maintenance
·         A general check of the feeding equipment for proper function on a daily basis is critical. The H&L 100's maintenance menu enables you to easily test its various components.
·         The calibration of its parameters is of particular importance for the proper operation of the H&L 100. The software quickly walks you through the calibration procedure and tells you exactly what to do at every step.
·         We recommend that you have your H&L 100 serviced by a qualified technician at least once a year. This gives peace of mind: you can be sure that your automatic calf feeder is ready for the next rearing cycle.
