Suzie, those symptoms of Pesti are for older cattle, although in a paddock situation it is rare to see any symptons at all. In a feedlot, especially on induction, when young animals are under stress you may see symptons, but more likely other diseases will show such as pneumonia as Pesti lowers the immunity to other diseases, and it is the other diseases that kill them, a bit like AIDS.
What Jilleroo would be referring to is the possibility of your calf being born a PI (persistently infected). If a cow gets Pesti while pregnant between a certain no. of days, I can never remember exactly, and if she doesn't lose the calf then it will usually be born a PI. It's immune system not being developed when infected, it treats the virus as being part of itself, ie friendly and will not develop antibodies to it and be always infected.
These calves when born are often weeds or have something wrong with them, they usually do not grow as well as their cohorts. A t weaning many good judges can pick them out from the rest. Occaisionally they can appear normal, in fact there have been show champions that have been found to be PI's.
In my 1st lot of calves I had 1 definate PI, he did not grow well so I held him over the winter, a couple of new cows I got were exposed to him, they had their first calves ok, but the following year the younger one had a very small weedy heifer that was born without an anus, another great cow had a very small bull calf, in fact he could walk under the belly of other calves, he survived but never did well. Their were another couple of suspects, but I suspect all of these were from Pesti. I then tested the cows and all had antibodies to Pesti, a couple showed evidence of recent infection.
Most of my cows have lifetime immunity now, but all heifers are now vaccinated before going in calf, then a yearly booster after calving. Otherwise since the herd is now clean, as the older cows are replaced with young, the herd would gradually become susceptible again setting up for a big crash from socialising over the fence for example.
Got 3 calves today, the first two were heifers, the 3rd a bull, he was a heifers calf, I had to give a bit of a hand, in fact had to get the chains on both legs and walk him out, a moderate pull, my feet against her buttocks, but all is well, I can't afford to lose any bull calves, they are a bit scarce.
I think I got mange, an itchy rash on my leg just getting worse, my little foxie Jamie is very itchy and she sleeps with me, she swings off the pigs that Bo gets then I handle them, usually throw them up onto the truck with help from my leg. Anyhow I am going to get a scalpel blade out tomorrow and do a scraping, see if I can find any mites under the microscope. I will go into town tomorrow and see what I can get for them. I might just go to CRT and pick up some Equimec, for the dogs at least, but I might work out a dose rate for me.
Suzie you must be a bit of a youngster not having seen round 50c coins, your hubby must have been a bit of a cradle snatcher. Anyhow that was a fortunate discovery, amazing how the loose change adds up. Aren't the round ones worth a bit more now? I have a couple of the paper $100 notes in the filing cabinet, they are supposed to be worth a bit more too. A few years ago afellow brought them in to pay his bill, he had been keeping them, I felt real bad about taking them from him, I couldn't bring myself to bank them, so they are sitting there for my grandchildren.
