Relationship between parasites and performance in nutrias (
Myocastor coypus
) under intensive
production system

Statement of the Problem:
The nutria (
Myocastor coypus
)
is a semiaquatic rodent indigenous to South America, and
has been introduced around the world for fur and meat
farming. Concerning the parasitological aspects, little data
has been published in the literature of nutria farms. There is
also lack of data regarding to relationship between parasites
prevalence and performance of nutrias. The purpose of the
study was to evaluate incidence of parasites in nutria farms
in the Czech Republic, and then to compare performance of
animals with a high and a low parasites occurrence.
Methodology & Theoretical Orientation:
The study was
conducted on 13 farms from which, feces samples were
collected for three years. After analyses, the farms were
divided into two groups, farms with a high respectively a low
prevalence of parasites, where fertility and growth of young
nutrias were evaluated.
Findings:
The evaluation of the farms indicated infection
with the following parasites:
Trichuris
sp.,
Stryngyloides
sp.,
Trichostrongylus
sp.,
Eimeria seidelli
,
Eimeria nutriae
,
Eimeria coypi
and
Eimeria myopotami
; however, animals did
not show clinical sings of the parasitic infections. In farms
with the high parasites prevalence, litter size approximately
16% and number of weaned nutrias 18 % were lower than
in farms with the low prevalence. Slaughter weight of young
nutrias at the age of eight months was to 18% lower in males
and 24 % in females from a group with a high prevalence of
parasites.
Conclusion & Significance:
The results of the present study
indicate that even the farmed nutrias did not show clinical
sings of parasitic infections, are a reservoir of parasites. A
high prevalence of parasites decreases fertility and growth
of nutrias. Therefore, it is important to pay an attention to
prophylaxis in farms to reduce spreading of parasites and
improve performance.
Speaker Biography
Eva Tumova works on interaction of genotype and environmental conditions, including
nutrition, in poultry, rabbits and nutrias. Her recent research is oriented on the effect
of quantitative feed restriction in chickens, rabbits and nutrias on digestive physiology
and meat quality. She also conducts experiments with housing systems, oviposition
and egg quality in laying hens. Her teaching activities are in Bachelor, Master and
Doctoral programmers in poultry, rabbits and fur animal husbandry.
