Re: %GP
How imporant is a sire's %GP? If I have an EX 91 cow from a bull with 45% GP, is she less of a cow than another one of mine who is EX 91, but by a bull with 70% GP? Is a VG 85 cow from a bull with 80% GP, better than either one.
I can see how %GP might help you decide what bulls to use, but I wouldn't put too much faith in it as a great individual breeding tool.

Re: %GP
We ae not tlaking about, which cow is better, but which bulls we trust more, certainly ove 100 daughters with over 80% GP helps to trust a bull.
I totally disagree on cow values, obviously a Cow VG89, class winner at the national show from my homebull Don, on the paper values less than a G+82 James x Bellwood(Bormio full sister), that I have.
In Italy if a cow is not in the top 1000 ranking, she could hardily send bull to A.I.

Re: %GP
Few of us are lucky enough to send a bull to a stud and have him make the lineup.
Your truly great cow, Donetta, from which Don decends, is a Rockman daughter. What if you had been told reliably, that Rockman daughters had bad legs and were hard milkers? That was true of the AVERAGE Rockman daughter.
Would you have thought, "I don't need that." and not purchased her? No bull has all or even most daughters like the "average".(or it wouldn't be an average) It is the true cowman who can pick the winner.
We had two Rockman daughters, both decent cows. One was a high GP, the other a VG. Not EX legs, not fast milkers, but certainly good enough.
Proofs are only guidelines. Remember who picks the bulls to be sampled, and of those, the ones who pick bulls making it into the main stud lineup. It's the studs selling the semen. Certainly not the dairymen milking the daughters, who have to actually milk the daughters to see who are really the good bulls, by then the studs are pushing a new set of bulls.
I would have more confidence in a bull, like your Don, picked and used by a worthy breeder, than the ones picked by the computer.
If you breed from the average, you will have an average herd. From the average herd you cull to get a top herd.

Re: %GP
Who You are?
How do You know that well my families?
Well My father puchased her because He saw her mother ! If you read my messages you could see that a lot of bulls we are using are not high indexes bulls, what we look at first of all are pedigrees, than daughters and in the end at numbers.
In fact We are currently flushing the Don daughter, Neve, and all Donnetta family.
Just one more things, Olimpia comes from Donnetta. Come to see my herd and see how it is average. It's not our fault if regulations say the only young bulls sired by top 100 Bulls can be sampled, so sometimes we have to use high indexes bull.

Re: %GP
RDC--I am just using your bull as an example, that one's own judgement is worth trusting. I believe the bottom half of a pedigree is the most important when selecting a bull to use or an animal to buy.
We are very fortunate in the USA to be able to use semen on any bull we choose, whether from a private collection or a stud. The government only compiles the information.
If the bull is collected properly from a US goverenment approved facility, and he meets US health requirements, his semen can be shipped worldwide. It is the importing countries who keep the bull out, if they choose to do so.

Noway for Mtoto to have soft feet!!!!
Which were their mothers?
Mtotos' could be thick that's why I suggest to use Champion on Mtotos'.
Mtoto's Uk proof is -2.6 for milking speed.
Champion's canadian score is 78 ( 85 average ).
Looks like you could be waiting a while for them to finish.
Could It be so even beacause they produce more milk then the others?
People said so even about a Bull of Mine, (they said that he was slow), Posal Aerostar Donay, He is the 10th bull with 99% rel. for Milk Production World Wide, 2nd Aerostar son, only WInchester is better.
I do not trust people with average on 1st lact. cow of 80000 or 90000 kg, obviously for them Donay and Mtoto, +20% on the average for milk production, are extremely slow.
