Effect of porcine somatotropin on metabolism, testicular size and sperm characteristics in young boars
ABSTRACT The aim of this study was to evaluate the effect of pST injections on metabolism, testicular size, and sperm characteristics in young boars. Sixty 22-day old piglets were divided into two groups: pST (n=30) and Control (n=30). The pST group was submitted to pST injections (90µg/kg body weig...

Sixty 22-day old piglets were divided into two groups: pST (n=30) and Control (n=30). The pST group was submitted to pST injections (90µg/kg body weight) every three days up to 330 days of age. Blood collections were performed weekly. Testicular weight was measures at 22, 82, 142, 202 and 365 days of age. Libido and fresh semen characteristics were evaluated between 150 and 210 days of age. Semen characteristics were also evaluated during a 72h storage period (15ºC). Testosterone, albumin, and phosphorus blood concentrations were higher in the pST group (P |

The pST group had a higher IGF-I concentration in seminal plasma (P=0.05) and higher testicular weight (P<0.001) compared to the Control group. The pST group had higher ejaculate volume (P<0.001), total sperm count (P=0.047) and number of inseminating doses/ejaculate (P=0.047). During the 72h storage period, the pST group had a lower number of morphological alterations (P<0.001) compared to the Control group. In sum, pST injection in young boars increased testosterone concentration, testicular size, and sperm quality.
RESUMO O objetivo deste estudo foi determinar o efeito da administração de pST sobre o metabolismo, o tamanho testicular e a qualidade espermática de cachaços jovens. Foram usados leitões com 22 dias de idade, divididos em dois grupos: pST (n=30) e controle (n=30). O grupo pST foi submetido a injeções de pST (90µg/kg de peso vivo) a cada três dias até 330 dias de idade. Peso testicular foi avaliado aos 22, 82, 142, 202 e 365 dias de idade. Libido e qualidade do sêmen fresco foram avaliados entre 150 e 210 dias de idade. Qualidade espermática foi avaliada durante refrigeração (15ºC) por um período de 72 horas. Concentrações sanguíneas de testosterona, albumina e fósforo foram maiores no grupo pST (P<0,05). O grupo pST apresentou maior concentração de IGF-I no plasma seminal (P=0,05) e maior peso testicular, quando comparado ao grupo controle (P<0,001). O grupo pST apresentou maior volume espermático (P<0,001), concentração espermática (P=0,047) e número de doses espermáticas por ejaculado (P=0,047). Durante o período de 72 horas de refrigeração, o grupo pST teve menor número de patologias espermáticas (P<0,001). Assim, conclui-se que a administração de pST aumenta a concentração sanguínea de testosterona, o tamanho testicular e a qualidade espermática de cachaços jovens.]]></description><identifier>ISSN: 0102-0935</identifier><identifier>ISSN: 1678-4162</identifier><identifier>EISSN: 1678-4162</identifier><identifier>DOI: 10.1590/1678-4162-9481</identifier><language>eng</language><publisher>Universidade Federal de Minas Gerais, Escola de Veterinária</publisher><subject>growth hormone ; pST ; semen ; swine ; testicle ; VETERINARY SCIENCES</subject><ispartof>Arquivo brasileiro de medicina veterinária e zootecnia, 2018-01, Vol.70 (1), p.73-81</ispartof><rights>This work is licensed under a Creative Commons Attribution 4.0 International License.</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c339t-615ea18bef81848c3b91b831cd4f014319fade8f02f0c0916274d100d719a2063</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,314,776,780,860,881,27901,27902</link.rule.ids></links><search><creatorcontrib>Rabassa, V.R.</creatorcontrib><creatorcontrib>Feijó, J.O.</creatorcontrib><creatorcontrib>Perazzoli, D.</creatorcontrib><creatorcontrib>Pereira, C.M.</creatorcontrib><creatorcontrib>Schild, A.L.P.</creatorcontrib><creatorcontrib>Lucia Júnior, T.</creatorcontrib><creatorcontrib>Corcini, C.D.</creatorcontrib><creatorcontrib>Schmitt, E.</creatorcontrib><creatorcontrib>Schneider, A.</creatorcontrib><creatorcontrib>Pino, F.A.B.D.</creatorcontrib><creatorcontrib>Bianchi, I.</creatorcontrib><creatorcontrib>Corrêa, M.N.</creatorcontrib><title>Effect of porcine somatotropin on metabolism, testicular size and sperm characteristics in young boars</title><title>Arquivo brasileiro de medicina veterinária e zootecnia</title><addtitle>Arq.
