Plant extracts have been recognized as beneficial to human health and have been evaluated as feed additive for domestic and companion animals. This study evaluated oregano and green tea extracts fed to Jersey cows from approximately 21 d before calving to 21 d after calving on milk production, milk composition, and blood metabolites as well as investigated immunological and antioxidant attributes. Twenty-four Jersey cows with 441 ± 27 kg of BW, 3.5 ± 0.3 of body condition score (BCS), and 2.7 ± 1.8 lactations were selected at approximately 28 d before the expected parturition date and were randomly assigned to three treatments with eight cows each: without plant extracts in diet (control ? CON), addition of 10 g per day of oregano extract (OR), and addition of 5 g per day of green tea extract (GT). Feed intake, BW, BCS, blood metabolites, hemogram as well as oxidative stress biomarkers were evaluated from approximately 3 weeks prepartum to 3 weeks postpartum (transition period) while milk production and composition were evaluated during the first 3 weeks of lactation. Plant extracts did not change BW, BCS, and DM intake (DMI) throughout the transition period, but OR increased in approximately 20% total digestive nutrients and metabolizable energy intake on days 15 and 16 postpartum compared with CON. In the prepartum, OR increased in 48% platelets count compared to the CON, while GT augmented in 142% eosinophils compared with CON. Oregano extract reduced the levels of reactive species in the erythrocytes in 40% during prepartum and postpartum compared with CON, while GT reduced its levels in 24 and 29% during prepartum and postpartum, respectively, when compared with CON. In the postpartum period, OR increased in 60% the carbonylated protein content compared with CON, while GT reduced in 45% the levels of reactive species in plasma compared with CON. During the postpartum, both extracts increased in 33% the concentration of reduced glutathione when compared with CON. Moreover, GT tended to decrease feed efficiency in 11% when compared with CON; OE reduced milk pH and somatic cell count when compared with CON. In conclusion, OE and GT did not expressively affect immunological attributes in blood but reduce some oxidative stress biomarkers without compromising productive traits of Jersey cows during the transition period.

Resumo: O objetivo deste trabalho foi determinar a compatibilidade entre ativos biológicos bacterianos e produtos químicos utilizados no sistema de produção de mudas pré-brotadas de cana-de-açúcar, e a compatibilidade mútua entre cinco bactérias diazotróficas e uma estirpe osmotolerante. Os produtos químicos utilizados foram o promotor de crescimento vegetal Biozyme TF, o inseticida Regent 800 WG (fipronil) e os fungicidas Priori Xtra (azoxistrobina + ciproconazol) e Comet (piraclostrobina). Os ativos biológicos compreenderam a bactéria osmotolerante Bacillus aryabhattai (CMAA 1363), e as diazotróficas Herbaspirillum seropedicae (BR 11335), H. rubrisubalbicans (BR 11504), Paraburkholderia tropica (BR 11366), Azospirillum amazonense (BR 11145) e Gluconacetobacter diazotrophicus (BR 11281). Cada bactéria foi exposta aos produtos na concentração máxima recomendada e semeadas em meio de cultura após 1, 6 e 24h de exposição, avaliando-se a sobrevivência celular para cada período com base no número de ufc.mL -1 . Foram construídas curvas de crescimento utilizando-se dados empregando a transformação logarítmica ln(ufc.mL -1 ) juntamente com os respectivos intervalos de confiança para cada tratamento determinado. Para avaliar a compatibilidade mútua entre as bactérias promotoras de crescimento e a osmotolerante foram realizados ensaios de inibição em sobre-camada. O isolado de A. amazonense foi incompatível com todos os produtos testados, enquanto que H. seropedicae, H. rubrisubalbicans, P. tropica e G. diazotrophicus se mantiveram viáveis quando expostos a todos os produtos, independentemente do período de exposição. Bacillus aryabhattai tolerou a exposição apenas ao Regent 800 WG. Não houve inibição mútua entre as bactérias diazotróficas e a bactéria osmotolerante, de modo que esta poderá ser introduzida no pool de bactérias diazotróficas utilizadas na produção de mudas de cana-de-açúcar. Abstract: The objective of this study was to determine the compatibility between bacterial biological assets and chemical products commonly employed in the production system of pre-sprouted sugarcane seedlings. Besides, it was investigated the mutual compatibility among five diazotrophic bacteria and one osmotolerant bacterial strain. The chemical products used were the plant growth promoter Biozyme TF, the insecticide Regent 800 WG (fipronil), the fungicides Priori Xtra (azoxystrobin + cyproconazole), and Comet (pyraclostrobin). The bacteria biological assets included the osmotolerant bacterium Bacillus aryabhattai (CMAA 1363) and the diazotrophic bacteria Herbaspirillum seropedicae (BR 11335), H. rubrisubalbicans (BR 11504), Paraburkholderia tropica (BR 11366), Azospirillum amazonense (BR 11145) and Gluconacetobacter diazotrophicus (BR 11281). Each isolate was exposed to the mentioned products in the highest recommended concentration, and then they were transferred to the culture medium after 1, 6 and 24h of exposition. The evaluation was performed for each period based on the number of cfu. mL -1 . Growth curves were constructed employing logarithmic transformation data for ln(cfu.mL -1 ) accompanied by their respective confidence intervals for each treatment in order to determine bacterial survivorship. To evaluate the compatibility among growth promoting and osmotolerant bacteria, the inhibition assays in overlay were performed. Azospirillum amazonense isolate was incompatible with all products tested, however Herbaspirillum seropedicae, H. rubrisubalbicans, Paraburkholderia tropica and Gluconacetobacter diazotrophicus were able to remain viable when exposed to all products, regardless the period of exposure. The bacterium Bacillus aryabhattai was tolerant only to Regent 800 WG. There was no mutual inhibition between the diazotrophic bacteria and the osmotolerant bacteria, which implies the possibility of formulating a biological product with the osmotolerant bacterium in the pool of diazotrophic bacteria for using on pre-sprouted sugarcane seedlings production system.
