Genetic polymorphism of myostatin gene in Sumba Ongole (Bos indicus) cattle and its association with growth traits

“…Several domestic farm animals’ MSTN gene expression has been studied for associations with performance and functional features [ 11 , 21 – 23 ]. One of the most important factors in the cattle breeding industry is the MSTN gene and the beneficial traits it is associated with [ 11 , 24 , 25 ].…”

“…The role of the MSTN gene in economic production has been identified in various breeds of beef cattle, such as Belgian blue [ 26 ], Nellore cattle [ 25 , 27 ], Piemontese young bulls [ 23 , 28 ], Russian cattle [ 2 ], Marchigiana bulls [ 3 ], and, Chinese yellow cattle [ 29 ]. The trait can be found in Australian beef cattle [ 30 ] and in some breeds of Indonesian beef cattle, such as the Peranakan Ongole (PO), the Belgian Blue × PO hybrid, and the PO × Pegolo Bali cattle [ 31 , 32 ].…”

“…European cattle breeds with heterozygous genotype variations, such as Limousine, exhibited better meat quality and growth performance than homozygous genotypes. However, it has been established that MSTN gene polymorphism and its association with growth traits in European cattle breeds [ 37 ], Angus cattle [ 11 , 12 ], Belgian Blue cattle [ 26 ], and Nellore cattle [ 25 , 27 ] and the association between the MSTN gene polymorphism and growth traits in SO cattle, one of the Bos indicus breed, have not been studied in depth. To date, the MSTN gene is considered polymorphic in other Ongole crossbred cattle, such as PO cattle, Bengali, or Zebu cattle ( B. indicus ) [ 32 ].…”

“…As it is known that the MSTN gene is related to productive qualities in other breeds of cattle, it is necessary to analyze in detail the role of the MSTN gene in SO cattle. The biological aspects of the gene have yet to be completely understood, despite its importance in beef cattle muscle development, carcass, and meat quality [ 25 , 26 , 30 , 38 ]. As one of the valuable genetic resources of Ongole beef cattle, this study seeks to evaluate the genetic variation of the MSTN gene and its association with growth traits in a population of SO cattle.…”

Influência do pH final nos parâmetros físico-químicos, bioquímicos e sensoriais associados à qualidade da carne de bovinos >i<Bos indicus>/i<

“…Animals, 11, 2291. https://doi.org/10.3390/ani11082291A maciez é uma das principais características da qualidade da carne bovina, sendo considerada prioridade pelo consumidor. A inconsistência na maciez pode influenciar as decisões de compra dos consumidores(Ferrinho et al, 2021). É conhecido que a maciez da carne é afetada por diferentes fatores, como sistema de produção, dieta, idade do animal no momento do abate, efeito do pH, entre outros.…”
