Global demand for food is increasing, which pressures for greenhouse gas emissions reduction or neutralization to mitigate the climate change. In this context, Brazil has developed technologies to produce beef with lower carbon emissions. This study aimed to evaluate a low carbon strategy for intensifying beef cattle raising in areas of consolidated use in sandy soils of the Brazilian Cerrado, West of Bahia's State, through enteric emissions, liveweight gain (LWG) and changes of stocks of soil organic carbon (SOC) from 0 to 40 cm layer. SOC calculations were performed in 2019 and 2021 using the DNDC model and Urquiaga et al. (2016) protocol, while enteric methane emissions used the ALU model. |

Abstract: We determined the polymorphism C242T of the aromatase gene (Cyp19) and its allelic frequency, as well as the effect of the variants on productive and reproductive traits in 71 purebred Santa Inês sheep, 13 purebred Brazilian Somali sheep, nine purebred Poll Dorset sheep, and 18 crossbred 1/2 Dorper sheep. The animals were genotyped using the PCR-RFLP technique. The influence of the animal's genotype on its performance or on the performance of its lambs was analyzed by the least square method. Another factor assessed was the importance of the animal's genotype in analysis models for quantitative breeding value estimates, and whether there were differences among the averages of breeding values of animals with different genotypes for this gene. In the sample studied, no AA individuals were observed; the AB and BB frequencies were 0.64 and 0.36, respectively. All Brazilian Somali sheep were of genotype BB. All 1/2 Dorper BB animals presented a lower age at first lambing, and the Santa Inês BB ewes presented a lower lambing interval. In these same genetic groups, AB ewes presented higher litter weight at weaning. This is evidence that BB ewes have a better reproductive performance phenotype, whereas AB ewes present a better maternal ability phenotype. However, in general, animals with genotype AB presented better average breeding values than those with genotype BB. |
