Título:  Genotype imputation in a tropical crossbred dairy cattle population.

Conteúdo:  The objective of this study was to investigate different strategies for genotype imputation in a population of crossbred Girolando (Gyr × Holstein) dairy cattle. The data set consisted of 478 Girolando, 583 Gyr, and 1,198 Holstein sires genotyped at high density with the Illumina BovineHD (Illumina, San Diego, CA) panel, which includes ∼777K markers. The accuracy of imputation from low (20K) and medium densities (50K and 70K) to the HD panel density and from low to 50K density were investigated. Seven scenarios using different reference populations (RPop) considering Girolando, Gyr, and Holstein breeds separately or combinations of animals of these breeds were tested for imputing genotypes of 166 randomly chosen Girolando animals. The population genotype imputation were performed using FImpute. Imputation accuracy was measured as the correlation between observed and imputed genotypes (CORR) and also as the proportion of genotypes that were imputed correctly (CR). This is the first paper on imputation accuracy in a Girolando population. The sample-specific imputation accuracies ranged from 0.38 to 0.97 (CORR) and from 0.49 to 0.96 (CR) imputing from low and medium densities to HD, and 0.41 to 0.95 (CORR) and from 0.50 to 0.94 (CR) for imputation from 20K to 50K. The CORRanim exceeded 0.96 (for 50K and 70K panels) when only Girolando animals were included in RPop (S1). We found smaller CORRanim when Gyr (S2) was used instead of Holstein (S3) as RPop. The same behavior was obse... Mostrar Tudo

Título:  Potential of basalt dust to improve soil fertility and crop nutrition.
Ano de publicação:  2022
Fonte/Imprenta:  Journal of Agriculture and Food Research, v. 10, 2022.
Páginas:  8 p.
Idioma:  Inglês
Conteúdo:  The search for higher yields, lower production costs, and increased sustainability in agriculture implies opti- mizing crop nutritional management. In this sense, basalt dust has shown potential to improve soil fertility and crop nutrition. Thus, the goal was to evaluate the potential use of basalt dust in a controlled environment. First, an experiment was carried out on soils with contrasting textures (sandy and medium) under a random design, with four replications. These soils were incubated with basalt dust doses for 90 days, and later analyzed for chemical properties. Then, after soil incubation, four experiments were carried out in a pot system, where maize and bean plants were grown, with four replications. Plant shoots were evaluated for dry weight and macro- and micronutrient accumulations. The results of the incubation test showed that basalt dust increased available phosphorus, potassium, calcium, and magnesium levels in the soil about twenty, ten, fifteen, and thirteen times higher than those without the basalt dust, respectively. Maize and bean plants grown in soils enriched with basalt dust showed macro and micronutrient accumulations, up to five times higher than plants without the use of basalt dust. These results showed the usefulness of basalt dust in aiding nutritional management in agriculture
