Llama
IgG and It's Role as an Indicator of Health Status |
|
Over
the last year many articles have mentioned the measurement of IgG
as a method of evaluating the future health of a newborn llama.
More farms are beginning to utilize this technique and
veterinarians look at the level of this protein in older animals
with signs of sickness finding indications that IgG may be useful
in determining treatments.

Testing
to Develop Normals on Newborn Crias from Birth to Weaning |
|
Forty
newborn crias were monitored for IgG levels every 3 weeks until
weaning. Due to schedule conflicts some period bleeds were
omitted. All of these crias were born between 1995 and 1996 in the
Pacific Northwest (of the United States of America). A total of 5
crias were transfused by intraperitoneal infusion to raise their
passive transfer above our required 800 mg/dl. All tests were done
on Triple J Camelid RID kits. Donald Jorgensen |

Cow
Colostrum: An Alternative Supplement for the Newborn Llama |
|
A
newborn llama goes from a sterile womb to an environment filled
with bacteria, viruses and toxins. Protection against these
possible sickness-causing invaders comes from the dam's colostrum.
Immunity is developed through her daily existence with exposure to
barnyard contaminants as well as immunizations she might have been
given over the years. Protection comes in the form of antibodies.

How
to Correct Abnormal IgG Levels in Newborn Llamas |
|
Triple
J Farms has developed a method of monitoring passive transfer in
the newborn llama by using a radial immunodiffusion test. To date
we have monitored over 300 mother IgG colostrum titers and the
next day serum levels of IgG in the cria. By observation of the
cria's activity, weight gain, and general health we have
determined what we consider to be adequate IgG levels in the 24
hour cria. A cria may not achieve this level due to a difficult
birth, poor milk, improper sucking reflex, lowered body
temperature, etc.

The
Advantages of Measuring IgG in Llama Colostrum |
|
For
the past seven years Triple J Farms has been studying the use of
the measurement of llama IgG in improving the management and
breeding of llamas. This paper is preliminary data on monitoring
the IgG concentrations in llama colostrum over several years and
its relationship to passive transfer and the health of newborn
crias.

Questions
and Answers About Llama IgG and Plasma Transfer |
|
Includes
six questions and answers. For example: Question #1 -
I'm not sure if my cria nursed much the first 24 hours, but she's
4 days old and seems healthy. Is is necessary to get an IgG done?
If so why?
