RESUMO - Sementes de feijoeiro (Phaseolus vulgaris L.), cv. Aroana e Carioca, foram submetidas a classificação pelo tamanho, utilizando-se uma serie de peneiras manuais com crivos oblongos. Em seguida, cada fração foi armazenada, sob condições normais de ambiente, e submetida a testes periódicos de germinação e de vigor (primeira contagem, velocidade de germinação e envelhecimento acelerado) durante seis meses, conduziu-se, também, um ensaio de campo durante a época "das águas". Concluindo-se que a classificação das sementes por diferenças de espessura corresponde a uma separação de níveis de qualidade fisiológica; no entanto, a decisão final quanto a classificação depende da proporção com que as sementes menores participam do lote. ABSTRACT - The effects of bean seed size on germination, vigor and yield of bean plant (Phaseolus vulgaris L.) cv. Aroana and Carioca were studied under laboratory and field conditions. The seeds were sized into classes differing by 0.4 mm in thickness. Physiological quality of seeds from size classes was evaluated using standard germination and vigor tests (first counting, speed of germination and accelerated aging test), during six months. The results showed that seed of the rnean and larger size classes were better in physiological quality than those of smallest classes. |

Improving the efficiency of production to reduce the environmental footprints is pivotal to the sustainability of livestock systems. Despite the advances in cattle feed efficiency (FE) measurement and identification of potential mechanisms involved, much is still unclear regarding the genetic and biological basis of this trait. Nevertheless, lipid and carbohydrate metabolism have been outlined as important in determining efficient and inefficient animals. To address the role of genes partaking in these processes and previously involved with residual feed intake (RFI), we carried out a liver expression profile in Nelore steers (n = 83). Six target genes (FABP1, FADS2, PPP1R26, RGS2, SLC2A5, and UCP2) were measured by qPCR analysis. A general linear mixed model approach was applied to associate them with dry matter intake (DMI), body weight (BW), metabolic BW (MBW, kg), DMI as a percentage of BW (DMI%BW), and average daily gain (ADG, kg/d). Residual feed intake (RFI), feed conversion ratio (FCR), feed efficiency (FE), Kleiber index (KI), and relative growth rate (RGR) were also evaluated. Our results support that increased expression of FABP1 gene was associated with enhanced values for RFI and DMI. Likewise, higher expression level of SLC2A5 was related to higher KI and RGR. There was no phenotypic correlation between RFI and ADG, BW, and MBW. The positive correlations between FABP1 and SLC2A5, and between FABP1 and FADS2 gene expression suggest a putative co-regulation affecting feed efficiency phenotypes.
