ENTAM – 2009 Annual Meeting Report of the Activities of the WG: “Mixer Feeder Wagons” Carlo Bisaglia – Giulio Fancello ART Tänikon, Switzerland 11-12 June 2009
2. Diffusion of MFW: timeline of major developments Early 1930s 1960s 1980s 1990s late 1990s 2000s TMR: 80 years of improving target and performances First test in laboratory
Alternative roles of MFW On-farm concentrate preparation Chopping straw and bedding Mixing organic wastes for co-digestive plants Chopping-mixing organic wastes for compost
The WG: “MFW” T = testing TP = test protocol TR = test results
Aims of the WG • Collect and compare different testing methods on MFW; • develop and improve a common methodology for testing MFW in the ENTAM frame; • plan common testing and/or research activities; • observe the carrying out of official tests; • recognizing of test reports; • publication and spreading of test reports; • collect test reports in the ENTAM web site.
WG milestones and activity • 21 September 2004: launch of the WG and first technical meeting, Treviglio, Italy “an inventory of test methodologies”. • 17-19 October 2004:presentation of the Technical Groups at the 12th meeting of the ENTAM members, Athens, Greece. • 6-8 September 2005: second technical meeting and first feed mixer wagon test, Gödöllő, Hungary “an attempt of a common standard”. • 2006: a first draft test protocol was circulated on ENTAM website • 2007: independent tests were carried out by Poland on the basis of the draft protocol • 28 April 2008: third technical meeting, Treviglio, Italy “focus on MFW test procedure” • 16-17 June 2008: 15th Entam meeting, Tänikon, Switzerland: a proposal for a new draft test protocol.
Discussion on aims for a MFW test Different aims are possible as: • Evaluation of single aspects (i.e.: noise test, power requirement, opt. mixing time, etc.) • Performance test • Duration of materials (i.e.: springs and suspension fatigue, bump test on axles, knife duration, walls wearing, etc.) • Safety assessment (i.e.: EN 703: 2004, etc.) • Road Code requirements verification.
The draft performance test protocol • Technical data and machine description (following a checked-declared statement). • Parameter to be evaluated as working time, mixing/chopping ability, power requirements, residues left in the box, etc. (following compulsory-optional criteria). • Test procedures (rations choice, hopper filling level replications, etc. following compulsory-optional criteria).
research activity and proposal for the ToC “Mixer Feeder” The automation of livestock represents a top priority for research For some animals (pigs, chickens, rabbits) the feeding automation is already accomplished, but for the cows and beef husbandry, some technological barriers to overcome still exist.
research activity and proposal for the ToC “Mixer Feeder” Many research project aimed to solve these problems and to adapt Feeder Mixer Wagons to the many changes that have characterized the agricultural panorama in the recent years as: i) the farm size has greatly increased; ii) the milking robots that are nowadays a fact; iii) the general and wide diffusion of TMR for non-grazing herds but also of PMR (Partial Mixed Ration) techniques for grazing ones; iv) find a relation between the feeding frequency and the feeding timing on cows production.
Besides the traditional Feeder Mixer Wagons, the development of Automatic Feeding Systems (AFSs) or Semi-Automatic Feeding Systems (S-AFSs) for TMR and their introduction on the market since the last 3-4 years have posed new questions for research as: i) possible changing in cow behaviour, ii) increasing in feed intake, iii) simple use, iv) technical performance (chopping and mixing ability), etc.
Manufacturers of automatic feeding systems (at present 11 firms world wide) are working following different design approaches making difficult, at present, the choice, the size and the comparison of these systems due to the lack of previous experiences. New research projects are introducing the possibility to use simulation models to compare design alternatives. Therefore, part of the ToC “Feed Mixers” could be the investigation in real conditions whether the TMR AFSs could be a valid solution under technical, economical and healthy aspects and which kind of test protocol are eligible for these machines, if any.
Some research projects have been recently carried out to classify the different design developed or to estimate their costs. Some researches aim to compare the AFS technological approaches or to assess their performances. Nevertheless the technical evolution of this sector could lead a “system approach” that could introduce in the AFS technologies for the automatic control of the diet components (NIR sensors) both for their quality assessment and for their traceability. Franz Nyedegger, ART Tanikon, Switzerland, and Carlo Bisaglia CRA-ING Treviglio, Italy of the ENTAM ToC “Mixer Feeder” are carrying on activities, at present independently, on this item. Bibliography and activity report will be available at the next ToC meeting.
