Number og boxes per AMS farm 1.4 1.0 1.3 1.8 13...| How Much Milk in Produced via AMS? • Figures from Norway 2011: • 35 % of all stalls are free-stalls (increasing due to animal welfare regulation – new tie-stalls are forbidden since 2004) • 50 % of cows are in free-stalls • 40 % of free-stalls have an AMS • 50 % of the cows in free-stalls are milked with AMS • Means that 25 % (soon 33 %) of all cows are milked with AMS The Driving Force for This Development • In Norway at least: • • • • • Pressure on Animal Welfare (new regulations) Example: Soft bedding mandatory from 2006 New tie-stalls forbidden from 2004 All cows in free-stalls from 2024 (eventually2034) All cows at least 8 weeks on pasture from 2013 (moved to 2014) • • • New building are costly Labor is expensive Costs are oil-driven • Quota for sales from 2002 BUILDING COSTS (44 barns) Næss, 2011) 305 days accumulated milk yield Free-stalls Simensen et al., 2010 Tie-stalls NKVet Symposium, Reykjavik 17 Cost example • Building cost are cheaper per barn up to 1000 m2 • 1000 m2 compares to appr. 50 dairy cows, means cheaper stalls for barns > 50 cows • In Norway hard to find roughage to > 100 cows (transportation costs) • With AMS you save 300,000 NOK in building costs • If you save one man-power each years it means 500600,000 NOK yearly • Cost of one AMS appr. 1,000,000 NOK • Increased milk production by 360 kg milk. With 60 cows this means 21,600 kg at NOK 2.80 = 60,500 NOK The Importance of The Free-Stall Construction NKVet Symposium, Reykjavik 19 The Free-Stall • Critical meassures for cleanlyness in stalls, cows, milk quality and cell count AMS (3,955 lactations) • AMS increases 305 days milk yield by 360 kg • BUT, • Not • in 1st parity!! MILKING • Animal movements very important: – Animals in and out – Sorting of animals to special needs sections – Milking stall or AMS/VMS is the wheel in the free-stall and have to be planned and placed with care – Must have a relation to cow movements to: • • • • • • • Calving area Cows having calved Drying off and dry period Insemination Pregnancy testing Treatment area (disease) Claw trimming area Control of Transport Mechanism for Infectious Agents •Active Passive •Cows and other calves • Personal movements •Trading live animals • Hygiene •Import restrictions (The Danes!!!) •Buying Equipements NKVet Symposium, Reykjavik 13th May 2013 23 Production impact from Corona-virus time Produksjonstap pga Corona-epid. Late impact ? diarea 24 NKVet Symposium, Reykjavik infected 25...| The importance of diagnostics! • Is it OK to supplement Selenium or vitamin E without knowing the cows really need it? • Is it OK to give vaccination without have the diagnosics in place beforehand? (BRSV, Mastitis (coli and others),)? • Is it OK to continue to treat cows for mastitis without knowing that you are on to a Str.agalactiae herd, or a Mycoplasma herd? • Etc., etc. Are also included???: Paratb? Salmonella? Mycoplasma bovis? Etc.

Restricted use of antimicrobials High degree of disease prevention (Salmonella, paratb, BVDV, Mycoplasma bovis, etc.) Free of several serious diseases (Tb, IBR/IPV, BLV, BVDV) Next to be attacked? (Corona, BRSV, Neospora etc.) Integrated highly sophisticated management systems including animal recording systems • • • In larger herds you have to: Know where you are (survey, diagnostics) Know the landscape and the connections (epidemiology) Know how to go through (tools, web-based information) Gather knowledge and necessary resources (humans) Set goals and train = and you will succeed NKVet Symposium, Reykjavik 13th May 2013 57
