“…The calcium found throughout pregnancy in agouti did not change compared to non-pregnant animals (7.62 ± 2:59 mg/dL) (RIBEIRO et al, 2008). These results corroborated the fact that changes in calcium levels, such as hypercalcemia, only occur when there is increased serum albumin or excessive venous stasis during sample harvesting (KERR, 2003).…”

“…The values of phosphorus levels in nonpregnant agoutis reported in the literature are 3.91 ± 1.41 mg/dL (RIBEIRO et al, 2008). In pregnant females, higher values of electrolytes may occur due to greater demand for fetus training (LANGE; SCHMIDTH, 2007), as in sheep, where it was observed that in the end of gestation, the concentration of phosphorus was close to the lower limit for the species indicating greater expenditure in these periods (BRITO et al, 2006).…”

“…Therefore, the ALT levels will only be changed when there is severe liver cell damage or muscle injury (KERR, 2003). The changes during pregnancy in agouti were defined based on reference values in non-pregnant animals (20 ± 4.6 IU/mL for Dasyprocta prymnolopha (KANEKO et al, 1997) and 28.08 ± 15.53 IU/mL for Dasyprocta sp (RIBEIRO et al, 2008).…”

ABSTRACT:The aim of this estudy was to establish the levels of serum total protein, albumin, globulin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), calcium, phosphorus, urea, creatinine, bilirubin and glucose during pregnancy in agoutis. Animals: Twelve pregnant agouti from the Center for the Study and Preservation of Wild Animals (CSPWA) of the Federal University of Piauí (UFPI) were used in this research. After identification of the estrus, the day of the coverage was confirmed by means of vaginal cytology with the visualization of spermatozoa (day zero) and confirmation of pregnancy by ultrasonographic examination after 15 days. Blood samples were collected by lateral saphenous vein puncture after physical restraint, every 10 days until the end of pregnancy, for biochemical analyzes. A completely randomized experimental design was used and the means compared by the Duncan test at 5% probability using the SAS (Statistical Analysis System). The results of the biochemical analysis of total protein, albumin, globulin, urea, creatinine, calcium, phosphorus, serum ALT, glucose, AST, total bilirubin, direct bilirubin and indirect bilirubin in pregnant agouti (Dasyprocta prymnolopha) did not differ when compared to nonpregnant females. The serum biochemical levels during pregnancy in agoutis, except for calcium and phosphorus, were unchanged compared to those found in the non-pregnant adult animal, as occurs in other species. The changes during pregnancy reflect the physiology and biology of wild species, elucidating information about the biochemical parameters during pregnancy, thus characterizing the animal as a benchmark for comparisons with other species, extolling its importance both for nature conservation and production in capivity.

“…No semiárido nordestino, esses animais são bem adaptados às características climáticas (Ribeiro et al 2008), assim, apresentam um grande potencial zootécnico, devendo--se, para tanto, direcionar um maior fluxo de pesquisas, no intuito de garantir sua conservação (Souza et al 2003) e a formação de criatórios com fins comerciais (Bonaudo et al 2005). Nos últimos anos, diversos conhecimentos têm sido gerados no tocante à biologia reprodutiva das cutias, como a caracterização morfológica dos ovários (Almeida et al 2003), tubas uterinas (Fortes et al 2005), placentação (Rodrigues et al 2003) e criopreservação de folículos pré-antrais (Wanderley et al 2012) em D. leporina, bem como o diagnóstico de gestação por ultrassonografia em D. prymnolopha (Sousa et al 2012).…”

RESUMO.-O objetivo deste estudo foi monitorar o ciclo estral em cutias (Dasyprocta leporina) criadas em cativeiro no semiárido brasileiro. Durante 70 dias, cinco cutias foram diariamente submetidas a citologia esfoliativa vaginal, e o monitoramento ultrassonográfico ovariano foi realizado a cada três dias. Um total de 8 ciclos estrais foi completamente monitorado, com duração de 28,2±0,7 dias, variando de 24 a 31 dias. Pela citologia esfoliativa vaginal, houve uma predominância de células superficiais nas fases de proestro e estro (P<0,05), seguida da predominância de células intermediárias no metaestro (P<0,05) e de células parabasais no diestro (P<0,05). Por ultrassonografia, não houve diferenças na morfologia ovariana durante as diferentes fases do ciclo estral (P>0,05). Os folículos foram identificados durante as fases estrogênicas (proestro e estro), com diâ-metro médio de 1±0,5mm. Em apenas 12,5% das fases luteais, corpos lúteos medindo 1,4±0,9mm foram identificados. Conclui-se que a associação da citologia vaginal e da ultrassonografia ovariana constitui uma alternativa viável para o monitoramento de ciclos estrais e identificação das fases estrogênicas em cutias da espécie Dasyprocta leporina. TERMOS DE INDEXAÇÃO:Dasyprocta leporina, roedores, colpocitologia, ecografia ovariana. INTRODUÇÃOAs cutias (Dasyprocta sp.) são roedores utilizadas frequentemente como fonte de alimento e extração de sua pele, couro e pelos por populações humanas (Lopes et al. 2004 The objective of the study was to monitor the estrous cycle in agoutis (Dasyprocta leporina) bred in captivity in Brazilian semiarid. During 70 days, five agoutis were daily subjected to vaginal exfoliative cytology, and the ovarian ultrasound monitoring was conducted every three days. A total of 8 estrous cycles were completely monitored, lasting 28.2±0.7 days, ranging from 24 to 31 days. By vaginal exfoliative cytology, there was predominance of superficial cells at proestrus and estrus phases (P<0.05), followed by the predominance of intermediate cells in the metestrus (P<0.05) and parabasal cells in diestrus (P<0.05). By ultrasound, there were no differences in ovarian morphology during the different phases of the estrous cycle (P>0.05). Follicles during the estrogenic phases (proestrus and estrus) were identified, with an average diameter of 1±0.5mm. In only 12.5% of luteal phases, corpora lutea measuring 1.4±0.9mm were identified. We conclude that the association of vaginal cytology and ovarian ultrasonography is a useful alternative for monitoring the estrous cycle and identifying the estrogenic phases in Dasyprocta leporina.INDEX TERMS: Dasyprocta leporina, rodents, colpocytology, ovarian echography.

“…Agouti is currently suggested as an experimental model for other species of hystricognath rodents that are vulnerable to extinction (Costa and Martins, 2008) because they can easily adapt to captivity and, thus, exhibit prolificity, precocity, and relatively short gestation period (Hosken and Silveira, 2001). These characteristics facilitate studying their physiology and exploring their zootechnical potential (Pachaly et al, 1999;Ribeiro et al, 2008).…”

View full text Add to dashboard Cite

Dasyprocta spp. (agouti) include wild rodents with highlighted ecological and economic importance, and are considered experimental models for endangered hystricognath rodents. Of late, development of techniques to conserve their genetic material as well as the formation of biobanks is increasing. In this context, this review describes the main advances in the knowledge of the reproductive morphophysiological specificities of agouti as well as the development and improvement of assisted reproductive techniques aimed at conservation, multiplication, and exploitation of their reproductive potential under captivity.
