Going off further topic here (again!), but out of interest TK, why bred at all from the low fertility ladies? My dad did operate a fairly loose spring system, so naturally our better cows calf in the spring every year. We have between 20-25% replacement rate, so for me to maintain the herd I need to get in around the 20heifers coming through the system every year. The LM bull by us was used to cleanup on any of the late calving cows who tend to be the ones with low fertility. Now that I'm using sexed I'd hope I can be alot more selective again, I'll be aiming for more than 20heifers, so as I can grow the herd over the next few years, but I'm not going to let my culling policy change at all if I can, and will avoid breeding from infertile cows if at all possible, esp if they are outside of the feb/march window.
When I say low fertility I mean lower. Anything not incalf this year in december will be gone (all going to plan). Lower would be cows that require 2+ attempts
Why breed from lower fertility at all? Simple, no cow was ever born who didnt have some useful traits, it's just a matter of how to limit their negative traits.
As I said anything that falls into 2 catagories is bred to beef if bred (classed as milkers non-breeders), 3 and it's a cull.
A lower fertility cow has that issue, but she may have high MS kgs, longevity, good SCC, good milking speed or high immunity. I fit the bull to need rather than my own personal ideology to make a balanced cow (mind you I weigh SCC and longevity more than most)
Breed for a single trait was what caused the flaw in every breeds, in holsteins it was yield with no consideration for fertility. In NZ it was fertility with little consideration for longevity or yield. In NR low SCC which ended with slow milkers (I could list them all but who cares)
Now the best holstein breeders are producing fertile moderate to high yield, NZ is importing holstein genetics to add to the mix, NR is selecting for yield and speed with minimum standards for fertility which bulls cannot go below.
We do have afew specific issues in the herd itself however, short teat length has definitely become a problem, with the cow leaking and having higher SCC. I might consider that Monty above for them, at the second I'm trying to select a high EBI HO with as positive teat length as possible for these cows.
I would definitely pick MO over HO for that issue, not enough recording of leakage in their breeding countries. In MOs it it a carry over trait from the past but the other option is to select a NR with high TMI for leakage on their system
Is there an argument for a Co-op modelled beef factory? Is it possible? Time to take these cowboys head on, it's no secret that meat processing is a lucrative business in this country.
Yes. Everytime I've asked this question of beef farmers, their answer is invariably "it was tried before" my pointing out that 90% of the milk coops of the past are gone now, some went bust too, is ignored
