“…Moreover, PHY increased ruminating activity of cows in SARA1 (Kröger et al, 2017), which likely increased salivary secretion, thus possibly diluting ruminal LPS and BA or increasing their passage out of the rumen. Furthermore, PHY may increase the reticuloruminal motility by stimulating chemo-sensitive epithelial receptors in the reticulorumen, abomasum, and duodenum (Mamaghani et al, 2013;Mendel et al, 2017). Therefore, it can be speculated that increased reticuloruminal motility enhanced the removal of deleterious compounds from the rumen as increased reticuloruminal motility also enhances digesta outflow of the reticulorumen.…”

Subacute ruminal acidosis (SARA) causes ruminal dysbiosis, thereby increasing the risk of systemic metabolic disorders in cattle. We recently showed that supplementation with phytogenic compounds (PHY) or autolyzed yeast (AY) counteracted negative effects of SARA by improving ruminal pH and microbiome. This study investigated the effects of an intermittent SARA challenge on the ruminal concentration of biogenic amines (BA) and lipopolysaccharides (LPS), as well as on the blood metabolome. We also evaluated effects of PHY and AY on the latter variables. Eight rumen-cannulated nonlactating Holstein cows were arranged in an incomplete 4 × 3 Latin square design with 4 experimental runs and 3 treatment groups. During each run, cows were switched from an all-forage diet (baseline) to an intermittent concentrate-challenge diet with a forage:concentrate ratio of 35:65 (dry matter basis) to induce SARA for 1 (SARA1) or 2 (SARA2) wk, separated by 1 wk of forage-only feeding. The 3 treatment groups were no additive as control, PHY, or AY. During baseline, SARA1 and SARA2 rumen fluid samples were collected for analysis of BA and LPS. Blood samples were taken during baseline and SARA1 for a targeted metabolomics approach. High-concentrate feeding caused a 9-fold increase in ruminal LPS during SARA1 and an 11-fold increase in SARA2 compared with the baseline. Elevated concentrations of ruminal BA were found during both SARA periods, with histamine showing the strongest increase during SARA1. Moreover, a decrease in phosphatidylcholines, lysophosphatidylcholines, sphingomyelines, and several AA in the blood during SARA1 were detected. Supplementation of PHY decreased concentrations of LPS (-43%), histamine (-66%), pyrrolidine (-38%), and spermine (-54%) in SARA1 and cadaverine in SARA2 (-50%). Moreover, cows that received PHY had higher concentrations of cholesterol (+26%), several AA, and phosphatidylcholines in SARA1 compared with control cows. For AY, decreases in ruminal ethanolamine (-21%), methylamine (-52%), histamine (-54%), spermidine (-44%), and spermine (-80%) in SARA1 were observed, whereas in the blood an increase in tryptophan was noticed. In conclusion, the SARA was associated with markedly increased concentrations of LPS and BA in the rumen fluid and undesirable shifts in the plasma metabolome. Supplementation of PHY and AY counteracted some of these changes and therefore may help in attenuating negative effects of high-concentrate feeding in dairy cattle.

“…In the context of the gradually restricted or fully banned use of antibiotics in the diets of food-producing animals, phytogenic feed additives like medicinal plants and their extracts have attracted wide spread attention due to their plant-derived property and growthpromoting effect (Lei, Yun, Kang, & Kim, 2018;Mendel, Chłopecka, Dziekan, & Karlik, 2017;Si et al, 2006). Numerous previous studies have shown that plant extract scan be effective in improving the growth and health of pigs (Windisch, Schedle, Plitzner, & Kroismayr, 2008).…”

This experiment was conducted to evaluate the effects of plant extract YGF251 supplementation in different protein level diets on growth performance, nutrient digestibility, blood profiles, fecal microbial shedding, and fecal gas emission in growing pigs. A total of 144 pigs (24.72 ± 1.54 kg) were randomly assigned to the treatments in a 2 × 3 factorial arrangement of dietary protein levels (15.50%, 14.00% or 12.50%) and plant extract YGF251 levels (0 or 0.05%) with 6 replications per treatment and 4 pigs per pen. Pigs fed low protein diets had reduced average daily gain (p < 0.05) and increased feed conversion ratio (p < 0.01) compared with pigs fed high protein diets. The apparent total tract digestibility of nitrogen was decreased (p < 0.05) when reducing dietary protein level. Fecal ammonia and hydrogen sulfide emissions were reduced (p < 0.05) when reducing dietary protein level. In conclusion, the results of the current study indicated that reducing dietary protein level impaired growth performance and nitrogen digestibility but reduced ammonia and hydrogen sulfide emissions in growing pigs. Dietary supplementation with 0.05% herbal extract YGF251 was not effective in improving growth performance, nutrient digestibility, or in decreasing gas emission in different protein diets.

“…Essential oils have become an integral part of everyday life and can be used as natural additives in many foods and in the compounding of cosmetics and perfumes, as well as in pharmaceutical industry because of their antibacterial, antifungal, antioxidant and anti-carcinogenic properties. 1,2 Croton is the second largest genus of Euphorbiaceae, with approximately 1200 species distributed mainly in the tropical regions of the world. 3,4 Several species of Croton present essential oils and active constituents such as terpenoids, flavonoids and alkaloids.…”

Caracterização do Complexo de Inclusão do Óleo Essencial de Croton zehntneri e β-Ciclodextrina Preparados Através da Secagem por Atomização e Liofilização Resumo: Croton zehntneri (CZ) é uma espécie aromática da família Euphorbiaceae, nativa do Nordeste do Brasil, rica em óleo essencial (CZEO) com propriedades antioxidante, vasorelaxante, bactericida e fungicida. Apesar dos inúmeros potenciais biológicos e farmacológicos, óleos essenciais são instáveis e possuem limitada solubilidade em água, características que podem ser melhoradas pela formação de complexos de inclusão com ciclodextrinas (CDs). No presente estudo, o complexo de inclusão de CZEO e β-CD foi preparado por co-precipitação acoplada à liofilização e secagem por atomização. O complexo de inclusão foi caracterizado por espectroscopia vibracional (espectroscopia Raman e FT-IR) e a eficiência de complexação determinada por cromatografia gasosa acoplada à espectrometria de massa (CG-EM). Foi observado que a co-precipitação acoplada à liofilização possibilitou uma maior eficiência de complexação quando comparada ao spray drying. A espectroscopia Raman confirma a formação do complexo de inclusão entre CZEO e β-CD por ambos os métodos de preparação.
