“…Our results indicated that BS and MCE increased FPCM yields, while decreased CH 4 emissions per kilogram of FPCM. Both additives have been shown to benefit the health of cattle, BS improved digestion and increased serum IgG and IFN-γ levels [ 31 , 32 ] and MCE improved intestinal morphology and reduced the incidence of respiratory diseases based on its antibacterial and anti-inflammatory effects [ 33 , 34 ]. In agreement with our results, Choonkham et al and Souza et al [ 35 , 36 ] also reported that BS increased milk yield in dairy cows.…”

“…To our knowledge, there were few studies on MCE in dairy cows. Previous researches have shown that MCE reduces small intestinal damage and respiratory morbidity in young animals [ 34 , 37 ]. Therefore, it could be speculated that the observed improvements in lactation performance may be due to the anti-inflammatory and immune boosting capability of MCE.…”

Background Ruminant livestock production is a considerable source of enteric methane (CH4) emissions. In a previous study, we found that dietary inclusions of Bacillus subtilis (BS) and Macleaya cordata extract (MCE) increased dry matter intake and milk production, while reduced enteric CH4 emission in dairy cows. The objective of this study was to further elucidate the impact of feeding BS and MCE on rumen methanogenesis in dairy cows using rumen metagenomics techniques. Results Sixty dairy cows were blocked in 20 groups of 3 cows accordingly to their live weight, milk yield, and days in milk, and within each group, the 3 cows were randomly allocated to 1 of 3 treatments: control diet (CON), control diet plus BS (BS), and control diet plus MCE (MCE). After 75 days of feeding experimental diets, 12 cows were selected from each treatment for collection of rumen samples for the metagenomic sequencing. Results showed that BS decreased ruminal acetate and butyrate, while increased propionate concentrations, resulting in decreased acetate:propionate ratio. The metagenomics analysis revealed that MCE reduced relative abundances of Methanobrevibacter wolinii, Methanobrevibacter sp. AbM4, Candidatus Methanomassiliicoccus intestinalis, Methanobrevibacter cuticularis, Methanomicrobium mobile, Methanobacterium formicicum, and Methanobacterium congolense. Both BS and MCE reduced relative abundances of Methanosphaera sp. WGK6 and Methanosphaera stadtmanae. The co-occurrence network analysis of rumen bacteria and archaea revealed that dietary treatments influenced microbial interaction patterns, with BS and MCE cows having more and stronger associations than CON cows. The random forest and heatmaps analysis demonstrated that the Halopenitus persicus was positively correlated with fat- and protein-corrected milk yield; Clostridium sp. CAG 269, Clostridium sp. 27 14, Haloarcula rubripromontorii, and Methanobrevibacter curvatus were negatively correlated with rumen acetate and butyrate concentrations, and acetate:propionate ratio, whereas Selenomonas rumiantium was positively correlated with those variables. Conclusions The present results provided new information for mitigation of enteric methane emissions of dairy cows by feeding BS and MCE to influence rumen microbial activities. This fundamental knowledge is essential for developing enteric CH4 reduction strategies to mitigate climate change and reduce dietary energy waste.

Digestive system and respiratory tract diseases, which are frequently seen in calves during the suckling period, suppress the development of the calves or cause deaths and great economic losses. In the present study, it was investigated whether Juniper aromatic water (JOW) would be suitable for promoting the health of suckling Holstein calves. Sixteen newborn calves (n = 4, in each group) were randomly selected and assigned to the following four treatments; G1: control group, fed with whole milk (WM) and calf starter (CS), G2: fed with 1.25% JAW supplemented WM and CS, G3: fed with 2.5% JAW supplemented WM and CS, G4: fed with 5% JAW supplemented WM and CS. The supplementation of JAW significantly reduced the incidences of digestive system and respiratory tract diseases in calves. The supplementation of JAW suppressed the growth of intestinal pathogenic bacteria at weaning age but did not affect the growth of lactic acid bacteria. It did not affect the urinary and kidney systems of the calves. JAW decreased oxidative stress concentrations while a non-significant increase occurred in antioxidant defence mechanism enzymes. It showed a significant increase in Immunoglobulin A, G, and M. The best result was observed in the supplementation of 1.25% JAW. The finding of the study showed that JAW, a by-product, can be used safely in the health rearing of calves.
