“…Generally, endoparasites remove essential nutrients from its host and by removing these organisms nutrients are utilized by its host for improved performance Several species of endoparasites have been found in the agouti. However, most investigators reported on the prevalence and presence of the parasites but not the effect the parasites had on the agouti (Griffiths, 1940;Cameron and Reesal, 1951;Goncalves et al, 2007;Lainson et al, 2007;da Silva et al, 2008;Suepaul et al, 2016).

“…Currently, limited information is available on the effects of parasites on performance parameters in the agouti. Due to the presence of numerous endoparasites (Griffiths, 1940;Cameron and Reesal, 1951;Lainson et al, 2007;da Silva et al, 2008;Goncalves et al, 2007;Suepaul et al, 2016), investigation of the effects of parasites on performance parameters is warranted.…”

The agouti (Dasyprocta leporina) is a rodent that is found in the Neo-tropical region. This animal is hunted for its meat but has recently been reared in captivity as a source of meat protein in rural communities. A 20-month experiment was carried out to evaluate the effect of an anthelmintic on the reproductive performance of the agouti (Dasyprocta leporina) reared in captivity. This experiment was conducted in the humid tropics of Trinidad and Tobago. Sixteen animals (15 females, 1 male) placed in each of the two treatment groups in a completely randomized study design. In treatment 1 (T1) animals were given subcutaneous injections of Endovet Ces® (Ivermectin/Praziquantel) at 0.2 mg/kg every three months. Treatment 2 (T2) was the negative control group where animals were not exposed to an anthelmintic. Reproductive data were collected at parturition which included birth weight, litter weight, litter size and gender of offspring. The results showed that there was no statistical difference (p > 0.05) between the treatment groups with respect to birth weight, litter weight, litter size and gender. However, agoutis that were dewormed had a higher birth weight (220.24 g vs 209.1 g) and litter weight (369.8 g vs 343 g). The same values were obtained for the litter size (1.7 vs 1.7) and animals that were dewormed had a higher female offspring to male offspring (2.41:1 vs 1.11:1). This experiment demonstrated that the use of an anthelmintic strategically in the management of captive reared agoutis had no statistical effect (p > 0.05) on the reproductive parameters. Therefore, these animals can be kept in captive conditions without being dewormed and produce efficiently with proper feeding and housing management.

In this review, information was summarized on endoparasites found in six non-domesticated neotropical animals. These mammals have the potential to be domesticated. The animals included three rodents, agouti (Dasyprocta leporina), lappe (Agouti paca), and capybara (Hydrochoerus hydrochaeris); a marsupial, manicou (Didelphis marsupialis insularis); and an artiodactyl, the collared peccary (Tayassu tajacu/Peccari tajacu) and a ruminant (the red brocket deer, Mazama americana). While there are many descriptions of the parasites present, the majority of publications failed to note the effect of them on the animals. Most information is available on endoparasites of capybara, while the endoparasites of the red brocket deer were the least reported. The manicou was reported to have had the most number of endoparasites, 44 species of parasites were reported, while there were only 24 endoparasites reported in the lappe. The most common parasites found in these neotropical animals were Paraspidodera uncinata, Strongyloides spp., Eimeria spp., Moniezia benedeni, Trichuris spp., Physocephalus spp., and Giardia spp. A large majority of the studies concluded that these animals were reservoirs for parasites that could affect domesticated livestock. Endoparasites of zoonotic significance were Echinoccocus spp., Trichuris spp., Giardia spp., and Cryptosporidium spp.

RESUMORodentia é a ordem de mamíferos que apresenta o maior número de espécies, representando 42% da biodiversidade mundial. No Brasil ocorrem 75 gêneros e 243 espécies que apresentam grande diversidade em sua morfologia, comportamento, modo de vida e distribuição. São considerados bons indicadores ambientais e o conjunto de informações a respeito desse grupo é fundamental para o delineamento de áreas destinadas à conservação. Entre os métodos aplicados para a avaliação da ciência, as análises cienciométricas permitem avaliar a produção científica em uma determinada área. Este trabalho objetivou realizar um estudo quantitativo da produção científica sobre a Ordem Rodentia no Brasil e, mais especificamente, no estado do Paraná, entre os anos de 2003 e 2012. O levantamento bibliográfico foi realizado por meio do banco de dados publicados no sítio do "Thomson Reuters Web of Knowledge", entre 2003 e 2012, e os trabalhos selecionados foram agrupados de acordo com o ano da publicação, bioma, temas e espécies pesquisadas. Foram identificados quatro artigos do estado do Paraná e 154 artigos do Brasil. O ambiente com maior número de publicações foi a Mata Atlântica. A maior parte das pesquisas foi desenvolvida na área de genética, com 31,8%. As principais espécies pesquisadas no período foram Akodon montensis, Akodon cursor e Oligoryzomys nigripes. O levantamento realizado por este trabalho contribui para o conhecimento do estado da arte do grupo e destaca a necessidade de se ampliarem os estudos onde esta ordem ainda não é estudada, para o melhor delineamento de áreas prioritárias à conservação.
