%GP


we got the neighbours dispersal catologue last week and he had used all the skagvale bulls we imported.
while reading the pedigrees we noted that skagvale confidence has 91% GP daus but is -0.1 for overall type and -0.3 for mammery system 66% reliability.
In the same catalogue we note that raider has 93% GP daus and a 995 reliability with OT being +1.4 and MS +1.1
leadoff also has 91% GP and an OT of +1.2 and MS 1.0 numerous other bulls like skychief and astrojet are all over 90%gp and +1
my question is how can a bull have so many GP daus and be minus for type?

Re: %GP


Skagvale bulls or cows are not main stream breeding it is disqalification for index breeding . For reliability 66% is big value pedigree ( think about index pedigree ) , at Skagvale bulls not have 500 daughters for good reliability and reset pedigree value at his index for type .

Re: %GP


I think also that %GP is heavily dependent on the quality of the herd to start with. Almost any bull will give you almost all GP in some herds whereas even the best type sires in the world could not make some herds average GP.
The overall type figures and udder scores are the scores relative to all other bulls being used at the same time. So if the Raiders outscore the SKagvales in that particular herd at that particular time then Raiders will get higher type scores than Skagvales. We have seen many examples of stock bulls in great herds getting very high percentage GP but not qualifying for high type score because either they did not do as well as other bulls being used at the time or the confidence level was very low or the parentage would not suggest a high type sire until reliability increased to prove otherwise.

I think you are right in those assumptions. A lot of the type score is based on how well the animal does relative to her herd mates. You can also really see this percentage of GP swing as bulls recieve their proof. Semen is then mated rather than just put on any old cow as test semen was used. Generally it also goes into better herds, so daughters have a better start in life. As the saying goes "They all have mothers!" And the top type bulls in Canada first crop sit at 78% GP or better, whereas the second crop bulls should improve heavily on this.

Re: %GP


these figures came from the HFAA and I dont think they apply just to this herd as all their confidences are either GP or VG
regarding the skagvale bulls, all bar high country were progeny test and all of them have in excess of 200 head registared plus what went into grade herds , some herds used 100 straws of each and have 30 or more daus of each milking, so I think that they have as many if not more daus around than most progeny test bulls.of course we knew that pedigree influence would mean that these bulls will have a minus proof

Re: %GP


% GP is a big question !!!

One of the highest bull of the moment,
the Storm son, Titanic, has a low % GP compared to other bulls but He has some really Type indexes.

How is that possible?

I think that people should be able to read pedigrees and understand what a bull is. I hope Titanic is not "The Titanic".

Yes, i agree, the industry as a whole should make more readily available explanations of how type scores are reached. And Titanic as a name did make me think when I was ordering him!!! But, bear in mind, all his use would be in test herds, some of which Good Plus would be the best animals in the herd. Also consider the "difference" in standards of classification for different countries. Canada has been and still is the toughest country for classification

Re: %GP


I disagree for the last part of you thread.

Canada is the toughest country for classification only for foreign bulls!!!

Titanic is just a F&L bull.
Do you use to look at bull's daughters pictures before buying and usying a bull?

I do and I will never use a Bull that has that kind of weak daughters, Titanic daughters are from Canada!!! and they are weak anyway !!!

Look how much weak he is!!! a Real "TITANIC"
