Resumo: This work had the objective to determine the puberty and the spermatic representation to the males puberty (n = 22) of the Boer breeding, being determined the concentration of testosterone in relation with body weight and scrotal perimeter from Day 30 to 300 of life between spermatic motility verses spermatic mass motility, spermatic vigor, defects bigger and smaller defects of the spermatozoa in the dry and rainy seasons. In the dry season these parameters had varied from 3,7±1,1 to 34,0±4,7 (body weight), from 7,9±0,8 to 25,7±2 (scrotal perimeter) and from 259,41±172,35 to 4613,41±2892 pc/mL (testosterone). The spermatic concentration varied from 0,96±0,60 x 109/mL to 2,15±0,73 x 109/mL, the forward individual motility from 35,4%±31,2% to 64.1%±29.1%, the mass motility from 1,7±1,6 to 3,1±1,1, vigor from 2,0±1,6 to 3,0±1,5, bigger defects from 16,9%±8,9% to 4.2%±2.7% and smaller defects from 17,5%±5,7% to 3,2%±1,6%. In the rainy season ranged from 9,7±2,3 to 28,1±6,9 (body weight) from 9,5±1,5 to 22,0±3,0 (scrotal perimeter) and from 521,9±311,27 to 3417,9±2021,77 pc/mL (testosterone). The spermatic concentration diverse from 0,90±1,46 x 109/mL 2,7±1,65 x 109/mL, the forward individual motility from 16,0%±21% to 62.0%±34%, the mass motility from 0,3±0,9 to 2,6±1,7, vigor from 1,1±0,9 to 2,8±1,8, bigger defects from 18,3%±3,6 % to 3%±1.2% and smaller defects from 16,1%±6,2% to 3,4%±1,4%. It was also registered positive correlation between the concentration , testosterone and body weight (r = 0,30; r = 0,43), testosterone and scrotal perimeter (r = 0,42; r = 0,52) and between body weight and scrotal perimeter (r = 0,93; r =0,88) in the dry and rainy seasons, respectively. Also was registered positive correlation between spermatic motility versus spermatic mass motility (= 0,93; r = 0,93), spermatic motility versus spermatic vigor (r = 0,94; r = 0,92), as well as negative response between individual motility gradual versus bigger defects of the spermatozoa (r = -0,28; r = -0,25) and between forward individual motility and smaller defects of the spermatozoa (r = -0,21; r = -0,30), respectively, in the rainy and dries seasons. At the third month of age, 70.0% of the animals born in the rainy season had presented penis detachment from the prepuce , fact that only occurred in the fifth month of life in 67,6% of the animals been born in the dry season. At the four and seven months, respectively, the penis detachment from the prepuce occurred in all the born animals. The results allow to conclude that the dry season delays the unleash of the puberty, that the plasmatic concentration of testosterone is directly related with the puberty and body weight, scrotal perimeter and penis detachment from the prepuce, can be an important signify of the beginning of puberty, certified with base in a set of reproductive parameters in the young male Boer goat.

Na estação seca esses parâmetros variaram de 3,7±1,1 a 34,0±4,7 (peso corporal) de 7,9±0,8 a 25,7±2 (perímetro escrotal) e de 259,41±172,35 a 4613,41±2892 pc/mL (testosterona). A concentração espermática variou de 0,96±0,60 x 109/mL a 2,15±0,73 x 109/mL, a motilidade individual progressiva de 35,4%±31,2% a 64,1%±29,1%, o turbilhonamento de 1,7±1,6 a 3,1±1,1, vigor de 2,0±1,6 a 3,0±1,5, defeitos maiores de 16,9%±8,9% a 4,2%±2,7% e defeitos menores de 17,5%±5,7% a 3,2%±1,6%. Na estação chuvosa oscilou de 9,7±2,3 a 28,1±6,9 (peso corporal) de 9,5±1,5 a 22,0±3,0 (perímetro escrotal) e de 521,9±311,27 a 3417,9±2021,77 pc/mL (testosterona). A concentração espermática variou de 0,90±1,46 x 109/mL a 2,7±1,65 x 109/mL, a motilidade individual progressiva de 16,0%±21% a 62,0%±34%, o turbilhonamento de 0,3±0,9 a 2,6±1,7, vigor de 1,1±0,9 a 2,8±1,8, defeitos maiores de 18,3%±3,6 % a 3%±1,2% e defeitos menores de 16,1%±6,2% a 3,4%±1,4%. Foi registrada correlação positiva entre a concentração de testosterona e peso corporal (r =0,30; r =0,43), testosterona e perímetro escrotal (r =0,42; r =0,52) e entre peso corporal e perímetro escrotal (r =0,93; r =0,88) nas estações seca e chuvosa, respectivamente. Também foi registrada correlação positiva entre motilidade espermática vs. turbilhonamento espermático (r =0,93; r =0,93), motilidade espermática vs. vigor espermático (r =0,94; r =0,92), bem como correlação negativa entre motilidade individual progressiva vs. defeitos maiores dos espermatozóides (r = - 0,28; r = -0,25) e entre motilidade individual progressiva e defeitos menores dos espermatozóides (r = -0,21; r = -0,30), respectivamente, nas estações chuvosa e seca. Aos três meses de idade, 70,0% dos animais nascidos na estação chuvosa apresentaram desbridamento do pênis, fato que somente ocorreu no quinto mês de vida em 67,6% dos animais nascidos na estação seca. Aos quatro e sete meses, respectivamente, o desbridamento ocorreu em todos os animais nascidos nas duas estações. Os resultados permitem concluir que a estação seca retarda o desencadeamento da puberdade, que a concentração plasmática de testosterona está diretamente relacionada com a puberdade e que o peso corporal, perímetro escrotal e desbridamento do pênis, podem ser indicadores importantes do início da puberdade, certificada com base num conjunto de parâmetros andrológicos obtidos no macho caprino jovem da raça Boer.Submitted by (edna.saturno@ufrpe.br) on 2016-10-07T13:07:20Z No. of bitstreams: 1 Filipe Queiros Gondim Bezerra.pdf: 347211 bytes, checksum: 57418693331f5977fdbc1b87348c5c9e (MD5)Made available in DSpace on 2016-10-07T13:07:20Z (GMT).

description This work had the objective to determine the puberty and the spermatic representation to the males puberty (n = 22) of the Boer breeding, being determined the concentration of testosterone in relation with body weight and scrotal perimeter from Day 30 to 300 of life between spermatic motility verses spermatic mass motility, spermatic vigor, defects bigger and smaller defects of the spermatozoa in the dry and rainy seasons. In the dry season these parameters had varied from 3,7±1,1 to 34,0±4,7 (body weight), from 7,9±0,8 to 25,7±2 (scrotal perimeter) and from 259,41±172,35 to 4613,41±2892 pc/mL (testosterone). The spermatic concentration varied from 0,96±0,60 x 109/mL to 2,15±0,73 x 109/mL, the forward individual motility from 35,4%±31,2% to 64.1%±29.1%, the mass motility from 1,7±1,6 to 3,1±1,1, vigor from 2,0±1,6 to 3,0±1,5, bigger defects from 16,9%±8,9% to 4.2%±2.7% and smaller defects from 17,5%±5,7% to 3,2%±1,6%. In the rainy season ranged from 9,7±2,3 to 28,1±6,9 (body weight) from 9,5±1,5 to 22,0±3,0 (scrotal perimeter) and from 521,9±311,27 to 3417,9±2021,77 pc/mL (testosterone). The spermatic concentration diverse from 0,90±1,46 x 109/mL 2,7±1,65 x 109/mL, the forward individual motility from 16,0%±21% to 62.0%±34%, the mass motility from 0,3±0,9 to 2,6±1,7, vigor from 1,1±0,9 to 2,8±1,8, bigger defects from 18,3%±3,6 % to 3%±1.2% and smaller defects from 16,1%±6,2% to 3,4%±1,4%. It was also registered positive correlation between the concentration , testosterone and body weight (r = 0,30; r = 0,43), testosterone and scrotal perimeter (r = 0,42; r = 0,52) and between body weight and scrotal perimeter (r = 0,93; r =0,88) in the dry and rainy seasons, respectively. Also was registered positive correlation between spermatic motility versus spermatic mass motility (= 0,93; r = 0,93), spermatic motility versus spermatic vigor (r = 0,94; r = 0,92), as well as negative response between individual motility gradual versus bigger defects of the spermatozoa (r = -0,28; r = -0,25) and between forward individual motility and smaller defects of the spermatozoa (r = -0,21; r = -0,30), respectively, in the rainy and dries seasons. At the third month of age, 70.0% of the animals born in the rainy season had presented penis detachment from the prepuce , fact that only occurred in the fifth month of life in 67,6% of the animals been born in the dry season. At the four and seven months, respectively, the penis detachment from the prepuce occurred in all the born animals. The results allow to conclude that the dry season delays the unleash of the puberty, that the plasmatic concentration of testosterone is directly related with the puberty and body weight, scrotal perimeter and penis detachment from the prepuce, can be an important signify of the beginning of puberty, certified with base in a set of reproductive parameters in the young male Boer goat.
