Para determinar e analisar economicamente o periodo otimo de pastejo de bovinos de corte, em pastagem nativa, sob as taxas de lotacao de 2,0, e 3,3 ha/animal para a pastagem sem adubacao e 1,4; 2,0 e 3,3 ha/animal para a pastagem adubada, respectivamente, referentes aos trabalhosT1, T2, T3, T4 e T5. Os experimentos foram obtidos de um experimento desenvolvido pela EMBRAPA-UEPAE de Teresina, na "Regiao de Mimoso" de Campo Maior, Piaui, no periodo de 22 de marco a 01 de novembro de 1978 (225 dias). O instrumental analitico foi baseado no metodo do valor atual, para o calculo do custo operacional de producao e das receitas brutas e liquidas, considerando uma taxa de juros reais com capitalizacao continua de 1% ao mes. Utilizou-se da analise tabular e uma funcaode producao de modelo quadratico, ajustada pelo metodo de minimos quadrados ordinarios, para cada tratamento. As estimativas obtidas permitiram a determinacao do periodo otimo de pastejo e a segunte ordenacao crescente de rentabilidade para os cinco tratamentos considerados: a) ao preco de Cr$ 110,00/kg de peso vivo - T3, T4, T5, T2, T1; b) ao preco de Cr$ 132,00/kg de peso vivo - T3, T4, T5, T2 e T1 e C) ao preco de Cr$ 154,00/kg de peso vivo - T3, T4, T5, T2 e T1. |

Background: Integration of high throughput DNA genotyping and RNA-sequencing data allows for the identification of genomic regions that control gene expression, known as expression quantitative trait loci (eQTL), on a whole genome scale. Intramuscular fat (IMF) content and carcass composition play important roles in metabolic and physiological processes in mammals because they influence insulin sensitivity and consequently prevalence of metabolic diseases such as obesity and type 2 diabetes. However, limited information is available on the genetic variants and mechanisms associated with IMF deposition in mammals. Thus, our hypothesis was that eQTL analyses could identify putative regulatory regions and transcription factors (TFs) associated with intramuscular fat (IMF) content traits. Results: We performed an integrative eQTL study in skeletal muscle to identify putative regulatory regions and factors associated with intramuscular fat content traits. Data obtained from skeletal muscle samples of 192 animals was used for association analysis between 461,466 SNPs and the transcription level of 11,808 genes. This yielded 1268 cis- and 10,334 trans-eQTLs, among which we identified nine hotspot regions that each affected the expression of > 119 genes. These putative regulatory regions overlapped with previously identified QTLs for IMF content. Three of the hotspots respectively harbored the transcription factors USF1, EGR4 and RUNX1T1, which are known to play important roles in lipid metabolism. From co-expression network analysis, we further identified modules significantly correlated with IMF content and associated with relevant processes such as fatty acid metabolism, carbohydrate metabolism and lipid metabolism. Conclusion: This study provides novel insights into the link between genotype and IMF content as evident from the expression level. It thereby identifies genomic regions of particular importance and associated regulatory factors. These new findings provide new knowledge about the biological processes associated with genetic variants and mechanisms associated with IMF deposition in mammals.
