The present study was carried out to investigate the effect of fresh and dry eucalyptus leaves on feed intake, digestibility, rumen fermentation activity, blood serum biochemical, milk yield and composition, feed conversion and economic efficiency of lactating buffaloes. Twenty lactating multiparous Egyptian buffaloes in 3rd and 5th lactation seasons and weighed 550 kg on average were used in complete randomized design after 8 weeks of calving (peak period) and assigned into five similar groups of four buffaloes each according to milk yield and live body weight. Animals were individually fed on a basal ration (BR) consisted of 40% concentrate feed mixture (CFM), 30% fresh berseem (FB) and 30% rice straw (RS). The first group was un supplemented and served as a control group (G1). Those in the second and third groups were supplemented with 50 and 100 g of fresh eucalyptus leaves per head per day for low level (G2) and high level (G3). Animals in the fourth and fifth groups were supplemented with 15 and 30 g of dry eucalyptus leaves per head per day for low level (G4) and high level (G5). G3 recorded significantly the highest digestibility coefficients of all nutrients and feeding values followed by G2, G5 and G4, whereas control one (G1) had the lowest values. Ruminal pH value tended to decreased with Eucalyptus leaves additive. Group 3 showed significantly the highest TVFA’s and the lowest NH3-N concentration followed by G2, G5 and G4, while G1 had the opposite trend. Moreover, G3 revealed significantly the highest concentrations of total protein and globulin and the lowest urea, urea-N and creatinine and activity of SGOT and SGPT enzymes in blood serum followed by G2, G5 and G4, while G1 had reverse values. However, serum albumin concentration was nearly similar for the different groups. Group 3 recorded significantly the highest feed intake (DM, TDN and DCP), yield of actual milk and 7% FCM, milk composition (fat, protein, lactose, SNF, TS and ash) and milk constituents yield followed by G2, G5 and G4, while G1 had the lowest values. Also, G3 recorded significantly the lowest amounts of DM, TDN and DCP per 1 kg 7% FCM followed by G2, G5 and G4, while G1 had the highest amounts. At the same time, G3 recorded significantly the highest values of feed cost, output of 7% FCM yield, net revenue and economic efficiency and the lowest feed cost per kg 7% FCM followed by G2, G5 and G4, while G1 had the opposite values. In conclusion, addition of fresh eucalyptus leaves at the level of 100 g/head/day recorded the best improvements in feed intake, digestibility, rumen fermentation activity, some blood serum biochemical, milk yield and composition, feed conversion and economic efficiency of lactating buffaloes.

“…Cows with robust immunity are often able to clear pathogenic bacteria during invasion of the udder. In addition to their powerful antibacterial influence, essential oils can be used as an alternative to antibiotics to improve feed efficiency, nutrient use, and animal health ( 64 , 74 ). Dietary supplementation with black seed oil, chamomile oil, or cretian origanum oil starting 8 weeks before calving enhanced immunity in dairy cows ( 74 ).…”

Alternatives to antibiotics for treatment of mastitis in dairy cows

Mastitis is considered the costliest disease on dairy farms and also adversely affects animal welfare. As treatment (and to a lesser extent prevention) of mastitis rely heavily on antibiotics, there are increasing concerns in veterinary and human medicine regarding development of antimicrobial resistance. Furthermore, with genes conferring resistance being capable of transfer to heterologous strains, reducing resistance in strains of animal origin should have positive impacts on humans. This article briefly reviews potential roles of non-steroidal anti-inflammatory drugs (NSAIDs), herbal medicines, antimicrobial peptides (AMPs), bacteriophages and their lytic enzymes, vaccination and other emerging therapies for prevention and treatment of mastitis in dairy cows. Although many of these approaches currently lack proven therapeutic efficacy, at least some may gradually replace antibiotics, especially as drug-resistant bacteria are proliferating globally.

“…Recent research has demonstrated the efficacy of some herbs with antimicrobial, antifungal, anti-inflammation, and immunoreactive properties [1][2][3][4]. Research on dairy cows using herbs as feed additives reported a significant decline in the somatic cell count in milk, suggesting healing of inflammation in the mammary glands [5][6][7][8][9]. However, dietary herbal feed additive alone is insufficient to cure mammary inflammation in mastitis cases.…”

Effects of different sterilization methods of herbal formula on phytochemical compounds and antibacterial activity against mastitis-causing bacteria

Background and Aim: The current phytobiotic industry is struggling to determine a proper sterilization method for an herbal formula that comprises multiple plant extracts. Hence, this study aims to investigate the effects of two sterilization methods of herbal formula on phytochemical compounds and antibacterial activity against mastitis-causing bacterial isolates. Materials and Methods: The herbal formula comprised the extracts of Piper betle leaves, Curcuma domestica, and Curcuma zanthorriza. We applied two sterilization methods – sterilization using 0.45 μM syringe filter and sterilization using an autoclave at 121°C for 15 min. After sterilization, we measured phytochemical contents (phenol and flavonoid) of the herbal formula. Using the disk diffusion method, the antibacterial susceptibility test of the sterilized herbal formula against mastitis-causing bacterial isolates was conducted. Tetracycline, erythromycin, and penicillin – common antibiotics for mastitis therapy in dairy farms – were used as standard antibiotics. Results: Compared with autoclave sterilization, syringe filter sterilization resulted in less (p<0.05) phenolic and flavonoid contents. Against Escherichia coli and Staphylococcus aureus, the filter sterilized herbal formula (E. coli: 65.9%-73%; S. aureus: 6.2%-18.1%) markedly reduced the antibacterial activity than the autoclave-sterilized herbal formula (E. coli: 2.1%- 3%; S. aureus: 4.5%-10.7%). Conclusion: This study establishes that autoclave sterilization of the herbal formula is the best sterilization method that exerts minimal adverse effects on the phytochemical compounds and could sustain the antibacterial efficacy against mastitis-causing bacteria. Hence, the herbal formula could be used as an alternative treatment for bovine mastitis.
