ABSTRACT - The objective of this work was to evaluate the effect of the addition of whole-crude oilseeds of linseed, sunflower, and soybean to the diet of Jersey cows, in the first third of lactation, on the following characteristics: intake, apparent nutrient digestibility, milk production and its variables, energy corrected milk, feed efficiency, energy balance, milk fatty acid profile, and blood metabolic profile. Eight multiparous Jersey cows were used in a double Latin square design. The treatments were the experimental diets with the oilseeds, and calcium salts of fatty acids were used as the control. Protein digestibility was lower for soybean, whereas that of ether extract was higher in the control, not differing between the evaluated oilseeds. There was no difference between oilseeds for milk production, milk production corrected for fat, milk nutritional content, feed efficiency, energy balance, and blood metabolic profile. The levels of milk monounsaturated fatty acids increased with the use of sunflower. Higher levels of cis-9, trans-11 conjugated linoleic acid (CLA) in milk were observed in the control. The addition of the evaluated whole-crude oilseeds to the diet of Jersey cows in the first third of lactation does not affect milk production variables, feed efficiency, energy balance, and blood biochemical profile, but alters the fatty acid profile. RESUMO - O objetivo deste trabalho foi avaliar o efeito da adição de grãos integrais das oleaginosas linhaça, girassol e soja na dieta de vacas Jersey, no primeiro terço da lactação, sobre as seguintes características: consumo, digestibilidade aparente dos nutrientes, produção de leite e suas variáveis, leite com correção energética, eficiência alimentar, balanço energético, perfil de ácidos graxos do leite e perfil metabólico sanguíneo. Oito vacas Jersey multíparas foram utilizadas em delineamento duplo quadrado latino. Os tratamentos foram as dietas experimentais com as oleaginosas, e sais de cálcio de ácidos graxos foram utilizados como o controle. A digestibilidade da proteína foi menor para a soja, enquanto a do extrato etéreo foi maior no controle, sem diferir entre as oleaginosas. Não houve diferença entre as oleaginosas para produção de leite, produção de leite corrigida para gordura, conteúdo nutricional do leite, eficiência alimentar, balanço energético e perfil metabólico sanguíneo. Os teores de ácidos graxos monoinsaturados no leite aumentaram com uso do girassol. Níveis mais altos de ácido linoleico conjugado cis-9 trans-11 no leite foram observados no controle. A adição das oleaginosas integrais avaliadas na dieta de vacas Jersey, no primeiro terço da lactação, não afeta as variáveis de produção de leite, a eficiência alimentar, o balanço energético e o perfil metabólico sanguíneo, mas altera o perfil de ácidos graxos.

The diversity of Paenibacillus species was assessed in the rhizospheres of four cultivars of sorghum sown in Cerrado soil amended with two level of nitrogen fertilizer (12 and 120 kg/ha). Two cuItivars (IS 5322.C and IS 6320) demanded the higher amount of nitrogen to grow, whereas the other two (FBS 8701.9 and IPA 1011) did not. Using the DNA extracted from the rhizospheres, a Paenibacillus-specific PCR system based ou the RNA polymerase gene (rpoB) was chosen for the molecular analyses. The resulting PCR products were separated into çommunity fingerprints by DGGE and the results showed a clear distinction between cultivars. In addition, clone libraries were generated from the rpoB fragments of two cultivars (IPA 1011 and IS 5322.C) using both fertilization conditions, and 318 selected clones were sequenced. Analyzed sequences were grouped into 14 Paenibacillus species. A greater diversity of Paenibacillus species was observed in cultivar IPA 1011 compared with cultivar IS 5322.C, Moreover, statistical analyses of the sequences showed that the bacterial diversity was more influenced by cultivar type than nitrogen fertilízation, corroborating the DGGE results. Thus, the sorghum cultivar type was the oveniding determiinative factor that influenced the community structures of the Paenibacillus communities in the habitats investigated. |
