“…menthol enhanced Ca net flux rates determined for ovine rumen epithelia in Ussing chambers from 8.60 ± 1.43 to 13.24 ± 0.91 nmol/cm 2 •h and Na-mediated short-circuit currents (Rosendahl et al, 2016). In dairy cows, oral administration of 1.2 g essential oils with menthol as the major compound increased plasma Ca from 2.46 to 2.53 mM and decreased plasma urea from 4.28 to 3.92 mM (Braun et al, 2019).…”

In comparison to monogastric animals, ruminants show some peculiarities in respect to the regulation of mineral homeostasis, which can be regarded as a concerted interplay between gastrointestinal absorption, renal excretion and bone mobilisation to maintain physiological Ca and phosphate (Pi) concentrations in serum. Intestinal absorption of Ca or Pi is mediated by two general mechanisms: paracellular, passive transport dominates when luminal Ca or Pi concentrations are high and transcellular. The contribution of active transport becomes more important when dietary Ca or Pi supply is restricted or the demand increased. Both pathways are modulated directly by dietary interventions, influenced by age and regulated by endocrine factors such as 1,25-dihydroxyvitamin D3. Similar transport processes are observed in the kidney. After filtration, Ca and Pi are resorbed along the nephron. However, as urinary Ca and Pi excretion is very low in ruminants, the regulation of these renal pathways differs from that described for monogastric species, too. Furthermore, salivary secretion, as part of endogenous Pi recycling, and bone mobilisation participate in the maintenance of Ca and Pi homeostasis in ruminants. Saliva contains large amounts of Pi for buffering rumen pH and to ensure optimal conditions for the rumen microbiome. The skeleton is a major reservoir of Ca and Pi to compensate for discrepancies between demand and uptake. But alterations of the regulation of mineral homeostasis induced by other dietary factors such as a low protein diet were observed in growing ruminants. In addition, metabolic changes, for example, at the onset of lactation have pronounced effects on gastrointestinal mineral transport processes in some ruminant species. As disturbances of mineral homeostasis do not only increase the risk of the animals to develop other diseases, but are also associated with protein and energy metabolism, further research is needed to improve our knowledge of its complex regulation.

“…In DF, milk urea was slightly lower in the HFA‐100 group, but the effect was not statistically significant (Table ). Previous reports about the influence of essential oils on milk yields and composition have been inconsistent (Braun, Schrapers, Mahlkow‐Nerge, Stumpff, & Rosendahl, ; Silva et al, ).…”

In contrast to natural and historical diets of wild and domesticated ruminants, the diversity of plant species is limited in diets of modern dairy cows. Are “production diseases” linked to this? We conducted a trial to test the effects of a multicomponent herbal feed additive (HFA) on health, performance and fertility traits. A dose‐finding study (DF) with 62 cows on 11 commercial farms compared a low (50 g) and a high (100 g) dose of HFA (HFA‐50, HFA‐100) with a placebo (PL). In a subsequent field trial (FT) with 280 cows on 30 commercial farms, HFA‐100 was compared to PL. Cows were randomly assigned to HFA and PL groups and received HFA or PL individually daily from 14 days pre‐ to 300 days post‐calving. Data were analysed with mixed effects models. No differences between HFA and PL were found regarding performance, body condition score and overall culling rates. A tendency towards lower milk urea for HFA‐100 compared to PL (p = .06) was found in DF. HFA significantly reduced elevated milk acetone observations (≥10 mg/L) in the first 10 lactation weeks (HFA‐100: 4%; HFA‐50: 4%; PL: 12%) in DF. HFA‐50 significantly reduced lameness incidence (HFA‐100: 11%; HFA‐50: 2%; PL: 14%) in DF. Calving intervals were 15 days shorter in HFA compared to PL in both trials, which could be confirmed by tendency (p = .07) in FT. In both trials, the proportion of test days with elevated somatic cell score (≥3.0) was significantly lower in HFA compared to PL (DF: HFA‐100: 40%, HFA‐50: 45% and PL: 55%; FT: HFA‐100: 38% and PL: 55%) which is also reflected by tendency (p = .08) in lower culling rates due to udder diseases in FT. HFA showed no negative impact on any of the measured parameters. The effects of HFA indicate a potential of phytochemically rich and diverse feed additives for dairy cows' nutrition and physiology.

“…The influence of essential oils on the transport of various ions through the gastrointestinal epithelium was noticed not only in human and rat colon [Kaji et al 2011], but also in the rumen epithelium in cattle and sheep [Rosendahl et al 2016]. Research on this issue was also carried out by Braun et al [2018]. The aim was to study the effect of a blend of essential oils (BTX12; PerformaNat GmbH, Berlin, Germany, patent US9693971) on the cation status and feed efficiency in dairy cows during lactation.…”

Due to the abuse of antimicrobial agents, microorganisms are increasingly showing resistance to antibiotics, which is a problem not only from a medical point of view but also from an economical perspective. Microbes acquire the ability to develop resistance to antibiotics, which puts the effectiveness of therapy in question. Therefore, there was an increased interest in substances found in plants, showing strong antimicrobial activity [Król et al. 2013, Lima et al. 2013, Różański and Drymel 2009, Grzesiak et al. 2018]. An effective natural alternative are essential oils. These natural plant extracts find their application in medicine, cosmetology, food industry [Herman and Herman 2015, Kaniewski et al. 2016] and in animal nutrition [Radkowska 2013]. In addition to the effect of better feed utilization, essential oils are also useful in the treatment and prevention in various animal species [Crowell 1999].
