myostatin gene

But surely it shouldn't be in native breeds....just talking from a Angus point of view I see new bulls like gear fury and westellen diageo are carrying it as for that bull Peter pershore he no more looks like an Angus . I say the neighbour's lim bull must have slipped in somewhere in the back breeding

AFAIK belgian blues started off from shorthorn cattle that lacked the gene, recessive might be the technical word. By in-breeding or crossing only animals with the double muscle within the shorthorn breed they eventually ended up with the belgian blue breed. It happened after WW2 when food was still scarce.

It's possible a bit of out crossing happened in Canada with angus cattle before they closed the herd book, now 10 or 12 generations on of pedigree breeding the recessive (?) gene has managed to sneak it's way in to pedigree angus cattle here. Or maybe it was always there.

Myostatin gene from my understanding is ok a trait, the problem is-if it becomes the double mystatin gene--as its the BB then! which not good for angus pb breeding... limousine had the myostatin gene, but its a ok gene... as for that pershore bull-no harm never was a true angus.. see his pics--more a black lim/bue cross.. along irish folk never used him...

I don't know but @patsy_mccabe or @tanko can point you in the right direction

they get one from each parent your not going to get a double nt821 off a friesian cow for example

Not many bulls have two Q genes afaik, are you looking at a bull that has two?

I see Claddagh McCabe has two Q genes which is very unusual for a Lim. Madison and Joskins have one Q and one F.

Just used 2 F’s and 2 Q’s for an example, thought it might be simpler

Have myostatin tested some of the cows, 2 F’s, 1F, F+Q, 1Q, 1N are some of the results, I just wanted to understand if 1 gene came from the dam & 1 from the sire, or is it a possibility of different options based upon the combination. That way I can avoid certain bulls for certain cows. I’d like to avoid 2Q’s or 2N’s. I’d No Calving issues with 2 F’s

ya ur right one comes from dam and one from sire best bulls to use on cows with a q or n are double f loki, eby etc. doesnt mean u cant use q/f but just more risk plenty of bulls with q gene used on blue cows without much hassle

The Q cows are 1st cross CH and 2nd gen LM. The N is a CHxAAxBB. I put Lodge Hamlet on a CH heifer once and had to section due to extreme muscle with bone. I now know that heifer is 1F 1Q. My ideal sequences are ++ 1F, 2F, 1F 1Q, 1F 1N

Can you tell the Myostatin status from the genomics test alone? I've suspected that if the calving difficulty figure is higher than the average of the parents, then the Q gene has been carried to the offspring.

I mean if it's so important, why don't ICBF include it in the genomics test?

Some fekin double muscled Limerick Hurlers atm...

Where can you see these results on ICBF?

I got a calf done during the summer as wasn't sure of sire (used 2 different straws) and it's blank. Does it take a while to get the results for myostatin?

That's great to know. Only seems to be available for animals genomic tested since 2021. I have one heifer here that is Myostatin F94L/Q204X. Surprised at her as she came back easy calving on the Genomics.

Is it possible to see the Myostatin for the AI bulls on the ICBF database?

Are they limousin? They call the double F94L, the profit gene, for good reason - less calving difficulty and better milk and fertility. Stick to double F94L bulls to breed replacements and maybe try a few tested F94L/Q204X on bigger framed cows with good calving difficulty.

Agree if ICBF showed the bulls myostatin it would be beneficial

As heifers ? Eby or lm2014. As cows ,if you’ve 3/4 bred limousines or good half breds. Blues only show on the road.

Ya they are LM & 3/4 LMX.

I just checked my CH bull results on icbf and he is showing up as nocopy for everything on the list so what does that mean?
