Resumo: | Two experiments have been performed to evaluate the efficiency of ultrasound to visualization the external genital of fetuses goat. The first study determined the ideal period to sex goat fetuses by the ultrasound in the transrectal way being considered external genital structures. Daily had been monitored, 94 fetuses, being Boer (n = 36), Alpine Brown (n = 31) and Anglo-Nubian (n = 27), from day 40th to 60th of gestation, using linear transducer of 6.0 and 8.0 MHz. The final positioning of the genital tubercle (GT) occurred at day 47.11 ± 1.45 in the males and at day 45.62 ± 1.36 in the females and visualization of the structures of the external genital in the day 49.42 ± 2.20 (scrotum), day 49.37 ± 2.19 (penis), day 49.23 ± 1.75 (nipples) and at day 49.98 ± 2.52 (clitoris). The scrotum, penis, nipples and clitoris had been only visualized, respectively, after days 2.28 ± 2.16, 2.23 ± 2.23, 3.62 ± 1.50 and 4.36 ± 2.27 of the end of the GT migration. The data had shown that the migration of the GT in the female fetus is earlier (P < 0.05) than in the male and that the visualization of the scrotum and the penis is earlier (P < 0.05) than nipples and clitoris, having no difference (P > 0.05) between same sex structures. It was concluded that ultrasound by the transrectal via is an important tool to identify the fetal sex in goat and that is possible to sex fetuses of the studied breeds before 55th day of gestation, considering only the visualization of the external genital structures. The second study the objective was to determine the ideal period to early sex goat fetuses proceeding from simple (SP) and twin (TP) pregnancy. Daily 94 fetuses of Boer (11 SP and 25 TP), Alpine Brown (10 SP and 21 TP) and Anglo-Nubian (8 SP and 19 TP) had been examined, from day 40 to 60 of gestation, to determine the day of the final positioning of the GT and the first visualization day of the scrotum, penis, nipples and clitoris, using a double frequency (6.0 and 8.0 MHz) linear transducer. The final positioning of the GT of male fetuses in the SP occurred in the day 46.83 ± 0.72 and in the females was at day 45.71 ± 1.10, with no difference (P > 0.05) between female and male fetus, as well as between breeds. The visualization of the scrotum occurred in day 49.17 ± 2.41, penis in day 49.25 ± 2.09, nipples in day 49.06 ± 1.78 and the clitoris in day 50.88 ± 3.26, having no difference (P > 0.05) between visualization days. The scrotum, penis, nipples and clitoris had been only visualized, respectively, after days 2.33 ± 2.35, 2.42 ± 2.19, 3.35 ± 1.46 and 5.18 ± 2.81 the migration end of the GT, with no difference (P > 0.05) between scrotum, penis and nipples and between nipples and clitoris, however the clitoris visualization was later (P < 0.05) than scrotum and penis. In TP, the final positioning of the GT of the male fetuses occurred at day 47.13 ± 1.59 and the females at day 45.54 ± 1.45, having difference (P < 0.05) between female and male fetus. The visualization of the scrotum occurred in day 49.43 ± 2.13, penis in day 49.33 ± 2.25, nipples in day 49.21 ± 1.66 and clitoris in 49.36 day ± 1.83, with no difference (P > 0.05) between the visualization days. The scrotum, penis, nipples and clitoris had been only visualized, respectively, after days 2.30 ± 2.15, 2.20 ± 2.25, 3.68 ± 1.54 and 3.82 ± 1.72 in the end of the GT migration, with no difference (P > 0.05)involving scrotum and penis, between nipples and clitoris, although the visualization of the clitoris was more delayed (P < 0.05) than the scrotum and penis. One concludes that the ultrasound by the transrectal via is an efficient to identify the goat fetal sex of the studied breeds before day 55th of gestation, only considering the visualization the external genital structures in simple and twin gestation. |

No primeiro estudo determinou-se o período ideal para sexar fetos caprinos pela ultra-sonografia transretal considerando as estruturas da genitália externa. Foram monitorados diariamente, 94 fetos das raças Boer (n = 36), Parda Alpina (n = 31) e Anglo-Nubiana (n = 27), do 40o ao 60o dia de gestação, utilizando um transdutor linear de 6,0 e 8,0 MHz, para determinar o dia do posicionamento final do tubérculo genital (TG) e o primeiro dia de visualização da bolsa escrotal, pênis, tetas e clitóris. O posicionamento final do TG ocorreu no dia 47,11 ± 1,45 nos machos e no dia 45,62 ± 1,36 nas fêmeas e a visualização das estruturas da genitália externa no dia 49,42 ± 2,20 (bolsa escrotal), dia 49,37 ± 2,19 (pênis), dia 49,23 ± 1,75 (tetas) e no dia 49,98 ± 2,52 (clitóris). A bolsa escrotal, pênis, tetas e clitóris somente foram visualizadas, respectivamente, após os dias 2,28 ± 2,16, 2,23 ± 2,23, 3,62 ± 1,50 e 4,36 ± 2,27 do final da migração do TG. Os dados mostraram que a migração do TG no feto fêmea é mais precoce (P < 0,05) do que no macho e que a visualização da bolsa escrotal e do pênis é mais precoce (P < 0,05) do que a das tetas e do clitóris, não havendo diferença (P > 0,05) entre as estruturas do mesmo sexo. Conclui-se que a ultra-sonografia pela via transretal é uma ferramenta importante para identificar o sexo fetal de caprinos visualizando as estruturas da genitália externa antes do 55o dia de gestação. No segundo estudo, teve-se o objetivo de determinar o período ideal de sexar fetos caprinos provenientes de gestação simples (GS) e dupla (GD), utilizando o transdutor linear de dupla freqüência (6,0 e 8,0 MHz). Foram diariamente examinados 94 fetos das raças Boer (11 GS e 25 GD), Parda Alpina (10 GS e 21 GD) e Anglo-Nubiana (8 GS e 19 GD), do 40o ao 60o dia de gestação, para determinar o dia do posicionamento final do TG e o primeiro dia de visualização da bolsa escrotal, pênis, tetas e clitóris. Na GS, o posicionamento final do TG dos fetos machos ocorreu no dia 46,83 ± 0,72 e das fêmeas no dia 45,71 ± 1,10, não havendo diferença (P > 0,05) entre feto macho e fêmea, bem como entre raças. A visualização da bolsa escrotal ocorreu no dia 49,17 ± 2,41, do pênis no dia 49,25 ± 2,09, das tetas no dia 49,06 ± 1,78 e do clitóris no dia 50,88 ± 3,26, não havendo diferença (P > 0,05) entre os dias ix de visualização. A bolsa escrotal, pênis, tetas e clitóris somente foram visualizados, respectivamente, após os dias 2,33 ± 2,35, 2,42 ± 2,19, 3,35 ± 1,46 e 5,18 ± 2,81 do final da migração do TG, não havendo diferença (P > 0,05) entre bolsa escrotal, pênis e tetas, entre tetas e clitóris, sendo a visualização do clitóris mais tardia (P < 0,05) do que a da bolsa escrotal e do pênis. Na GD, o posicionamento final do TG dos fetos machos ocorreu no dia 47,13 ± 1,59 e das fêmeas no dia 45,54 ± 1,45, havendo diferença (P < 0,05) entre feto macho e fêmea. A visualização da bolsa escrotal ocorreu no dia 49,43 ± 2,13, do pênis no dia 49,33 ± 2,25, das tetas no dia 49,21 ± 1,66 e do clitóris no dia 49,36 ± 1,83, não havendo diferença (P > 0,05) entre os dias de visualização. A bolsa escrotal, pênis, tetas e clitóris somente foram visualizados, respectivamente, após os dias 2,30 ± 2,15, 2,20 ± 2,25, 3,68 ± 1,54 e 3,82 ± 1,72 do final da migração do TG, não havendo diferença (P > 0,05) entre bolsa escrotal e pênis, entre tetas e clitóris, sendo a visualização do clitóris mais tardia (P < 0,05) do que a da bolsa escrotal e do pênis. Conclui-se que a ultra-sonografia pela via transretal é eficaz para sexar fetos através da visualização das estruturas da genitália externa, tanto em gestação simples quanto dupla, antes do 55o dia de gestação.Submitted by (edna.saturno@ufrpe.br) on 2016-08-12T14:02:16Z No. of bitstreams: 1 Cristiano Rocha de Aguiar Filho.pdf: 339447 bytes, checksum: 7967475b6ae9056cd19a6eebafa8adf7 (MD5)Made available in DSpace on 2016-08-12T14:02:16Z (GMT).

Two experiments have been performed to evaluate the efficiency of ultrasound to visualization the external genital of fetuses goat. The first study determined the ideal period to sex goat fetuses by the ultrasound in the transrectal way being considered external genital structures. Daily had been monitored, 94 fetuses, being Boer (n = 36), Alpine Brown (n = 31) and Anglo-Nubian (n = 27), from day 40th to 60th of gestation, using linear transducer of 6.0 and 8.0 MHz. The final positioning of the genital tubercle (GT) occurred at day 47.11 ± 1.45 in the males and at day 45.62 ± 1.36 in the females and visualization of the structures of the external genital in the day 49.42 ± 2.20 (scrotum), day 49.37 ± 2.19 (penis), day 49.23 ± 1.75 (nipples) and at day 49.98 ± 2.52 (clitoris). The scrotum, penis, nipples and clitoris had been only visualized, respectively, after days 2.28 ± 2.16, 2.23 ± 2.23, 3.62 ± 1.50 and 4.36 ± 2.27 of the end of the GT migration. The data had shown that the migration of the GT in the female fetus is earlier (P < 0.05) than in the male and that the visualization of the scrotum and the penis is earlier (P < 0.05) than nipples and clitoris, having no difference (P > 0.05) between same sex structures. It was concluded that ultrasound by the transrectal via is an important tool to identify the fetal sex in goat and that is possible to sex fetuses of the studied breeds before 55th day of gestation, considering only the visualization of the external genital structures. The second study the objective was to determine the ideal period to early sex goat fetuses proceeding from simple (SP) and twin (TP) pregnancy. Daily 94 fetuses of Boer (11 SP and 25 TP), Alpine Brown (10 SP and 21 TP) and Anglo-Nubian (8 SP and 19 TP) had been examined, from day 40 to 60 of gestation, to determine the day of the final positioning of the GT and the first visualization day of the scrotum, penis, nipples and clitoris, using a double frequency (6.0 and 8.0 MHz) linear transducer. The final positioning of the GT of male fetuses in the SP occurred in the day 46.83 ± 0.72 and in the females was at day 45.71 ± 1.10, with no difference (P > 0.05) between female and male fetus, as well as between breeds. The visualization of the scrotum occurred in day 49.17 ± 2.41, penis in day 49.25 ± 2.09, nipples in day 49.06 ± 1.78 and the clitoris in day 50.88 ± 3.26, having no difference (P > 0.05) between visualization days. The scrotum, penis, nipples and clitoris had been only visualized, respectively, after days 2.33 ± 2.35, 2.42 ± 2.19, 3.35 ± 1.46 and 5.18 ± 2.81 the migration end of the GT, with no difference (P > 0.05) between scrotum, penis and nipples and between nipples and clitoris, however the clitoris visualization was later (P < 0.05) than scrotum and penis. In TP, the final positioning of the GT of the male fetuses occurred at day 47.13 ± 1.59 and the females at day 45.54 ± 1.45, having difference (P < 0.05) between female and male fetus. The visualization of the scrotum occurred in day 49.43 ± 2.13, penis in day 49.33 ± 2.25, nipples in day 49.21 ± 1.66 and clitoris in 49.36 day ± 1.83, with no difference (P > 0.05) between the visualization days. The scrotum, penis, nipples and clitoris had been only visualized, respectively, after days 2.30 ± 2.15, 2.20 ± 2.25, 3.68 ± 1.54 and 3.82 ± 1.72 in the end of the GT migration, with no difference (P > 0.05)involving scrotum and penis, between nipples and clitoris, although the visualization of the clitoris was more delayed (P < 0.05) than the scrotum and penis. One concludes that the ultrasound by the transrectal via is an efficient to identify the goat fetal sex of the studied breeds before day 55th of gestation, only considering the visualization the external genital structures in simple and twin gestation. |
