NOVEMBER 2000 NEWSLETTER
Wazzzaaaaaaaahh.....!!! O.K. , it's childish
I know, but I can't really get myself into the swing of "Yuletide Felicitations",
"Merry Christmas", "Compliments of the Season" and all that jazz just yet.
I suppose Christmas might well be seen as a time for reflection on the
year past, assessment of goals and objectives achieved (or not) and re-dedication
of our commitment to new ideals to be striven towards in the new year (or
millennium, if you belong to the school of thought that says we were a
tad premature with our extravagances of last year). Apropos of all that,
was anybody bitten by the millennium bug ? Did anyone hear of any fatalities
attributed to this much maligned organism ? Nope, thought not. Great scam
though, wasn't it ? Even Santa managed to cope, though on reflection, his
operation may not be computerised yet.
On a personal note, I managed to implement
my usual quota of New Year Resolutions i.e. not a single one. To wit :
still smoking, still late with, well, just about everything, still virtually
computer illiterate, still can't dance (although brave efforts were made
to correct this shortcoming during a week on Collanmore Island in Clew
Bay), and finally, despite that wonderfully intensive week of expert instruction,
still couldn't tell you where the wind is coming from even with a weather
vane welded to the mast. I hope you all did a little better.
Next year I resolve to set more realistic
targets : try to have eaten breakfast before meeting my first customer,
try to read at least one book that owes more to literary merit than mass
market hype, ditto for at least one film, try to expose myself to at least
one live performance of , well, anything ; and if I achieve half of the
above, I will have improved my hit rate by amounts heretofore unrecorded.
It will undoubtedly not have gone unnoticed
that I have made no mention of my commitments to Pharmachem ; I would refer
you now to the word "realistic" strategically positioned in front of targets,
and let that be an end to it.
This is not to say that the rest of my colleagues
will not be beavering away as usual on all our behalves. At this point
I will take the opportunity to do a little bit of proselytising (most unlike
me, I hear you chorus). In the absence of any volunteers to ritually humiliate
themselves on a (nearly) monthly basis, may I suggest a resolution worthy
of adoption by all concerned : try to use Pharmachem more than you have
done ; if they annoy you, complain. Bitterly, irritably but above all,
constructively. It's the only way to improve the service. But, if we don't
use Pharmachem it will certainly wither, and with it will go any cohesively
structured representation of our interests as veterinary pharmacists.
That's it then, lecture over. It remains only
to wish all our readers a happy, prosperous and resolution fulfilled new
year. (I'll see you both in French's lads. It's my round). Anyone looking
for me, I'll be "heaving with pain, eating my pud...........true.."
Regards, Ian Mc etc.
The Irish Farmers Journal November 4th 2000
Winter Animal Health supplement highlights the increase in certain diseases:
Salmonellosis, Bovine Viral Diarrhoea, Calf
Diarrhoea and the respiratory diseases such as IBR, RSV and P13.
There has already been a 20% increase in the sale of vaccines this year,
with the three peak months to follow December, January and February.
In order to be adapt and have a clear understanding
of the many questions that will be forthcoming members are advised to refer
to their Pharmachem Handbook and update themselves on the relevant sections,
Respiratory Vaccines -
Bovine Respiratory Disease - Pneumonia in cattle.
These two articles cover in detail IBR, P13,
RSV. Calf Diarrhoea - Neo-Natal Calf Diarrhoea where the four main
causes of calf scour are covered,
Bacterial - E-Coli, Salmonella
Viral - Retlovirus, Coronavirus
Protozoans - Cryptosporidium,
the 1999 incidences are outlined in Figure
1 and the losses and gains in vaccines in Table 1.

Rotavirus Coronavirus E-Coli
K99 Salmonella Primary Course
Losses: Scourguard, Bovivac, Bovivac
Gains: Lactovac, Bovival
Grovax remains but availability is not dependable.

An area where prior to this season no product
was available and of major concern was Cryptosporidia. Cryptosponidia
is likely to cause one third of all calf scour. Transmission is by
faecal oral route. There was no treatment for infected animals until
the arrival of Halocur on the market this year. Halocur (halofuginone
lactate) (POM) Intervet; For the prevention of diarrhoea caused by
Cryptosporidium Parvum is new born calves on farms with a history.
It also treats cryptosporidiosis reducing
severity and duration of diarrhoea. Halocur has been demonstrated
to reduce oocyst excretion.
For oral use in calves after feeding
Calves 35kg—45kg: 8ml of Halcur once
a day for 7 consecutive days
Calves 45kg—60kg: 12ml of Halocur once
a day for 7 consecutive days
Treatment should start within 24—48 hours
of birth. Dosage @ 2ml/10kg body weight (toxicity @ 2 times dose)
Bovine Viral Diarrhoea (BVD)
Pregnancy related disease (i)
repeat breeder syndrome
(ii) embryonic death
(iii) chronically infected calves
Mucosal Disease: The calves born with
(a) Profuse watery diarrhoea
(c) Slobbering of saliva
And ill thrift
Blood sampling can be used to detect antibody
and virus. A bulk milk test can be used to screen the herd for BVD
