50,000 actual pounds of milk in a 365-day lactation … Is still an enormous achievement for any Holstein cow!

 

50,000 pounds  (actual, not “Mature Equivalent”—which old timers call “Maybe Eventually”)  is 137 pounds per day, every day for a year.     While a normal lactation less than the world record cows (82,600 pounds in Japan;  78,170 pounds in the USA;  68,900 pounds for Red & Whites), it is still a magnificent 99th percentile achievement for any dairy cow.

Our combine of  “real numbers”  AI studs may have the most sons of such cows

The ”Big Genomic AI studs” have adapted the IVF- ET technology to its most extreme level, thus their embryo donors never calve—never produce a drop of “real” milk.    The surgical process in use to harvest oocytes [eggs] from juvenile ovaries basically ruins the donor for any production.
With the exception of bulls big studs may buy from a handful of competing breeder-dairymen, you will never see a production record (or classification score) on the ancestry of their Genomic sires.
    There are now bulls in AI service with no verified lactation or classification records for their nearest three generations of dams and grandams.

Examples  of  “real numbers”  cows behind bulls we offer

54 HO 929  Joliam DR Gamechanger- ET     (aAa 6 1 5)     
A1A1 Beta Casein            $ 15
This even-tempered and intelligent bull is owned by No Bull Solutions.     His dam is the amazing USA world-record holder Selz-Pralle Aftershock 3918 who has twice exceeded 70,000 pounds (in fact, she did this back to back with only 55 days dry between!)  so has  three 50,000# lactations.
Her life production total of 317,150 pounds means she averaged 153 pounds per day in milk!!

54 HO 935  Jeffrey-Way Sporty *RC- ET       (aAa 2 4 3)                                           $ 15
This bull’s EX 94- 3E “Gold Medal” dam proves that polled in no way interferes with production.   Her last three lactations all exceed 50,000 pounds milk on 2x milking; with a life total to date of over 316,170 pounds at 12 years of age she continues to soldier on adding to exceptional totals.   Six of his seven nearest pedigree dams have made lactations above 40,000 pounds, proving this sort of behavior is maternally heritable.

Also worth considering:   
566 HO 1303  Misty-Moor Porsche- ET    (aAa 3 1 5)     A2A2
His lower Somatic Cell Scores reinforce that healthy udders produce more milk, like his momma!
                                       288 HO 0237  Adaway Rio 2183    (aAa 3 4 5)     A2A2  &  BB
He has three maternal dams all over 40,000 pounds at immature ages, and is our highest PTAM.
