“…The size and shape of the folds of the magnum were in agreement with the previous reports for quails (Artoni et al, 2001;Moraes et al, 2007;Carneiro et al, 2014). Although the studies for quails are not recent, this species did not undergo the same genetic selection that happened to chickens over time, so that these data can be compared even with the current quails in this experiment.…”

This study described changes in the serum biochemistry, morphology of genital organs, long bone, and eggshell during the daily egg formation cycle in Japanese quails. Sixty quails (18-wk) were distributed in 6 groups according to hours post-oviposition (POV): 0 hr POV (16h00), 2 hrs POV (egg in magnum), and 4, 8, 14, and 20 hrs POV (egg in uterus). The magnum had higher relative weight before the next ovulation (20 and 0 hr POV), and its tubular glands showed functional variation through periods: abundant eosinophilic, PAS+, and negative Alcian blue secretion at 0 and 2 hrs, empty glands aspect at 4 hrs, and filled again at 20 hrs POV. Serum albumin and total Ca had the highest value in the 2 hrs group, and the lowest in 8 and 14 hrs groups. Egg-cycle period affected the Ca% of the medullar bone of the femur and tibiotarsus, with the lowest mean at 14 hrs POV (06h00), and the highest mean after oviposition (0 hr POV), showing the recovery of Ca stores in long bones for the next egg cycle. Analysis of the eggshell using scanning electron microscopy evidenced that palisade layer formation starts during the night (8-14 hrs POV), and most parts are secreted during the day period. In conclusion, eggshell secretion in light periods, high magnum activity and medullary bone Ca deposition during midday and afternoon, as well as the ovulation/oviposition in the afternoon, are the main characteristics of the distinct physiological aspects of the egg cycle in quails.

ABSTRACT.-Oberlender G., Pontelo T.P., Miranda J.R., Miranda D.R., Zangeronimo M.G., Silva A.C., Menezes T.A. & Rocha L.G.P. 2014. Morphological and morphometric evaluation of prepubertal gilt ovaries, uterine tubes and uterus at different oestrus cycle stages. Pesquisa Veterinária Brasileira 34(1):83-90.

E-mail: zangeronimo@dmv.ufa.br Studies are performed in developing techniques/procedures that provide greater reproductive performance in farm animals, including pigs. In this sense, the study of gilts reproductive organs at different oestrus cycle stages for assessing the presence of abnormalities and/or other parameters that may affect the future animal fertility is important. In order to evaluate the morphological, morphometric and histomorphometric features of ovaries, uterus and uterine tubes (UTs) characteristics of prepubertal gilts at different oestrus cycle stages, reproductive tracts from 48 animals immediately after slaughter were obtained. After, the structures were dissected and removed, and the ovaries were used for classification of oestrus cycle stage of each gilt in follicular phase (FP) and luteal phase (FL). Then, morphometric evaluations of ovaries, UTs, uterine horns and uterine body were performed. Besides that, medial segments of UTs and uterus were fixed in Bouin solution, processed and included in paraffin, when histological sections of 5.0 micrometers (µm) were obtained and stained with Hematoxylin and Eosin. Histomorphometric analyzes using image capture system and specific software were performed. Afterwards, data were submitted to Student's t test for assessment the statistical differences (P<0.05) between the two different oestrus cycle stages (FP × LP) and between the placement of reproductive structures (right × left antimer). Among the gilts evaluated, 35 were in the FP and 13 in LP. There was no difference (P>0.05) between morphometric parameters of ovaries, UTs and uterus of gilts in FP and LP. Likewise, in respect to the placement of reproductive structures, both in the oestrus cycle stages, as in the general average, there was no difference (P>0.05). Regarding the histomorphometric variables, gilts classified in FP presented a higher (P<0.05) height of glandular and UT epithelium compared to animals in LP. On the other hand, the diameter of endometrial glands was higher (P<0.05) in gilts at LP compared to FP. Furthermore, gilts in LP presented a higher (P<0.05) proportion of endometrium occupied by glands, whereas animals in FP had a higher (P<0.05) proportion of connective tissue and blood vessels. In conclusion, in prepubertal gilts, the histomorphometric parameters as endometrial glands diameter, the height of glandular epithelium and of UT epithelium and the proportion of 1 Received on February 7, 2013.Accepted for publication on January 9, 2014.

“…O comprimento do oviduto de marrecas de Rouen é similar ao da galinha doméstica (30 cm) conforme citado por Dyce et al, (2004), porém é menor do que o de peruas Broad Breasted Bronze que possuem o magno com maior comprimento (38,4 cm) como relatado por Verna e Cherms (1964). Moraes et al (2007) ao estudarem codornas (Nothura maculosa) notaram o magno com menor comprimento (15,2 cm) do que o de marrecas de Rouen, igualmente como em patas (20 cm) como observado por Das et al, (1965). Além disso, o magno de marrecas de Rouen possui paredes mais espessas devido à presença de glândulas em seu interior (JUNQUEIRA; CARNEIRO, 2004) cuja função é a formação do albúmen do ovo (DYCE et al, 2004).…”

Foram estudados parâmetros biométricos do oviduto de 10 marrecas de Rouen (Anas playtrynchus) adultas em fase reprodutiva. As aves foram eutanasiadas, evisceradas e dissecadas e o oviduto foi retirado e pesado em uma balança de precisão e logo depois, estendido em uma superfície plana e sem sofrer estiramento, foi medido com uma fita métrica. Os segmentos anatômicos do oviduto foram separados e medidos individualmente. Posteriormente, contou-se as pregas do magno e istmo. Os dados foram submetidos a teste de T de Student com o nível de significância p≤0,05. Os resultados foram: peso do oviduto (47,78 ± 3,47gr) ; 7,80 ± 0,40 cm de infundíbulo; 29,09 ± 4,34 cm de magno; 10,11 ± 0,34 cm; de istmo; 6,45 ± 2,26 cm de útero; 8,01 ± 2,71 cm de vagina; comprimento médio do oviduto (56,00 ± 3,60 cm); número médio de pregas do magno (de 15,00 ± 2,30); número médio de pregas do istmo (13,00 ± 2,44) e, finalmente, vagina com média de oito anéis na porção inicial. Conclui-se que o oviduto é mais leve do que os de peruas e galinhas domésticas, porém, seu comprimento é maior do que o de galinhas. O magno é a maior porção do oviduto de marrecas de Rouen. O istmo e o útero possuem comprimentos maiores do que em galinhas.
