Background of Family Dairy Before robots: -milked 270 cows in a double 10 parallel parlor -6 full time employees After installing 3 Lely A3 robots: -milk 175 cows on the 3 robots -milk other 100 cows in parlor -within next year will go to 5 robots -Currently 4 fulltime employees
Background of Family Dairy One Robot = 4,500 – 5,500 lbs milk per day (Ideal) Currently: 58 cows/robot X 86 lbs/cow = 4,988 lbs/robot 2.9 – 3.1 Average Milkings per cow/day Free Flow System Pelleted grain/protein mix in robot, PMR in bunk
What the Lely Robot measures: Feed intake Activity* Rumination* Weight Milk yield Milk speed Milk Fat Milk Protein Robot visits Box times Per Quarter: - Pre Milk Time - Milk Time - Conductivity - Color + combinations of all of that... + combinations with calendar and health events. * = option
Benefits of Robot Weighs cow each milking Measures ‘Activity’ – breeding, sick cows, etc. Measures Conductivity – indication of SCC Quarter Milks each cow Robot automatically adjusts each day to the udder formation changes Robot displays ‘out of parameter’ readings for each cow (many reports to look at) Rumination Uniformity in Milking. Always shows up for work. Calls your cell when a problem occurs Easier on Cows (cull rate will lower) Etc.
Nutrition Preparation for Startup Top-dress robot pellet in parlor 1-2 weeks before startup – IDEAL Top-dress robot pellet on top of TMR when fed in bunk twice/day for 1-2 weeks - OK
Things to Remember & Do as a Nutritionist for Startup What producer feels: At startup 3 days of hell, 3 weeks of frustration, 3 months before things start clicking What to provide to producer: 1)Assist with pushing cows first couple days 2)Make regular weekly visits first 3 mo. 3)Moral support (very emotional time) 4)Watch graphs very closely each few days
Things to Remember & Do as a Nutritionist for Startup Do not look at milk production first as a performance indicator Look at refusals and # of milkings/day first and foremost, then production Get away from thinking on a herd level (one group ration) Feed hfrs and cows differently in robot Lots of info available, so make adjustments quicker than used to if needed
Nutrition Preparation for Startup 1) Feed Speed: Optimum setting is oz/minute (depends on if pellet or meal, meal lower and pellet higher) 2) Max & Min lbs feed/visit: 4-6 lbs max setting, 0 for min setting (default) (this is set based on herd production and feed table settings) 3) Must have feed tables set up correctly to herd parameters (Jeff will talk about)
Cornerstones of Feeding for Success 1) Ration fed at bunk is based on avg milk yield per cow minus 15 lbs. (even more for startup, lbs) 2) Robot pellet should be fed at min. of 4 lbs and a max. of 18 lbs in robot (approx). 3) Have a good hard pellet that is palatable and smells good to the cow. “Motivation for a cow to visit the robot is not due to pressure of udder but the want and need for concentrate.”
Collecting cows Unsuitable ration -> time in lactation 0 0 -> Energy Energy requirement Energy content feed fence: average milk production Concentrate
Most suitable ration -> time in lactation 0 0 -> Energy Energy requirement Energy content feed fence: average milk production minus 7 kg (15 lb) Collecting cows Concentrate

Nutrition Guidelines 1)Refusals: (avg # of times per day cow enters robot and can’t be milked yet) Above 1= doing well >1.5= sign of good diet but can push energy in PMR to get more milk <.8= feed in PMR an issue or displeased with robot or pellet <.4= larger herd issues or robot setting problems
Nutrition Guidelines 2) Rest Feed: (lbs of feed eligible to cow but never dispensed per day) Goal: Should be half of the number of cows per robot Look for if incorrect: –Who is causing the rest feed? –Are milkings low per cow? –Are settings correct?
Nutrition Guidelines 3) Rumination: (# minutes chewing) Goal min. avg for herd If >550: too much fiber in diet or full fill If <450: concentrates or starch possibly too high Possible adjustments: Change PMR Adjust amount of robot feed fed Rumination reliability should be 85 or higher on each cow if not adjust responders or bad responder
Achievement Important: > 2.5 milkings a cow per day > 1.0 refusal a cow per day < 5 failed milkings per robot per day >10% free time on the robot
Labor Cost vs. Robot Cost Compare Labor Cost vs. Robot Payment Robot - 6.5% Int for 7 yrs Payment of $32,819 / yr *Data from Tom Anderson (FBM Instructor)
Labor Cost vs. Robot Robot: 4700 # per day = 1,715,500 Annually Or: 17,000 cwts So : $33,000/17,000 cwts = $1.94 / cwt Or 5500 #/day = 20,075 cwts or = $1.64/cwt.
Labor Cost vs. Robot One FTE – (Full Time Equivalent Person) Should produce: 1,000,000–1,200,000 Pounds of milk annually. Remember the Robot: 1,700,000+ # Annually So the robot is replacing more than 1 FTE Equivalent.
Labor Cost vs. Robot Conventional Farm 1 FTE should manage 47 cows Robot Farm 1 FTE should manage 110 cows (this is still a question??)
Trends I am Seeing in Robots: 1. Increased production – Similar 2x to 3x 2. Equal or improved SCC counts 3. Herd health improving 4. Lower Turnover rates 5. Increased invent–market for robot cows 6. Networking of Robotic users 7. Movement to larger operations 8. Increased Pg rates Robotic Milking Technology
