Association of milk traits with SSCP polymorphisms at the growth hormone gene in the Serrana goat

Polymorphism in Growth Hormone Gene and its Association with Production Traits in Goats

“…The result showed significant statistical association of SSCP in the Eith exon regions with milk yields in the third and fourth lactation (P=0.044, P=0.034, respectively). This significant association of SSCP pattern for exon V with milk yield in the third and fourth lactation was in agreement with Malverio et al (2001), but contrary to Marques et al (2003). It had been described t h a t those animals with high milk yield revealed superior GH average levels when compared to those observed in animals with lower production, which indicated association of selection for milk yield with increased GH levels of blood (Sorensen et al, 2002).…”

Single nucleotide polymorphisms in intron 1 and intron 2 of Larimichthys crocea growth hormone gene are correlated with growth traits

“…SSCP analysis in GH has been reported in many farm animals, such as bovine and goat , Ferraz et al, 2006, Marques et al, 2003, Malveiro et al, 2001, but not as frequently in fish. Using denaturing polyacrylamide gel electrophoresis (DPAGE) and SSCP, Mo et al (2004) detected polymorphisms in intron 2 of GH1 among 162 carp individuals, which were from seven wild crucian carp colonies, two goldfish colonies, and one Fangzheng crucian carp colony.…”

“…The polymorphism in the exon region of olive flounder GH was associated with both body weight and head length (Ni et al, 2006). In domestic livestock, mainly in cattle and goats, some studies have shown associative effects between bovine GH (bGH) or goat GH (gGH) polymorphisms and milk yield (Høj et al, 1993;Marques et al, 2003;Lei et al, 2007), demonstrating close links between GH polymorphisms and some economically important traits. Therefore, GH has been considered a candidate gene for genetic marker identification for traits such as growth, productivity, milk production, carcass size, and immune response in livestock.…”

Biodiversidad caprina iberoamericana

“…Diversos estudos têm sido realizados visando a caracterização genética das raças caprinas portuguesas, baseados tanto na utilização de marcadores gené-ticos neutros (Bruno de Sousa et al, 2011), como marcadores monoparentais (Pereira, Pereira, Van Asch, Bradley e Amorim, 2005) ou polimorfismos de genes codificantes (Marques et al, 2003). Para além destes estudos que incluíram apenas raças portuguesas, outros trabalhos têm comparado estas no contexto das raças caprinas da Península Ibérica e com raças do Norte de África (Pereira et al, 2009), do Brasil , Ribeiro et al, 2012, assim como da Europa e do Médio Oriente (Cañon et al, 2006).…”
