Enterococcus faecium SF68® (SF68®) is considered one of the best
characterized probiotic active ingredient worldwide.
The strain has been isolated in Sweden from a healthy newborn baby in
the sixties and has been demonstrated to have clinical benefits for
humans (Wunderlich et al., 1989).
Furthermore, this probiotic strain is also effective in modifying the
immune response of piglets, young dogs, mice and cats (Bakhshi et al., 2006;
Benyacoub et al., 2005; Bybee et al., 2011; Scharek et al., 2005; Simpson et al., 2009).
Manufacturer: Cerbios-Pharma S.A. Switzerland 2
Cernivet® LBC ME10 is registered in EU for the use in:
• Calves up to 6 months,
• Chickens for fattening,
• Sows (2 weeks before farrowing and during lactation),
• Piglets up to 4 months and
• Pigs for fattening.

The application of probiotics to ruminant animals is relatively rare due to
the presence of pre-gastric fermentative rumen.
Nevertheless, a novel route of probiotic application via teat canal directly
into the mammary lumen of dairy animals has been developed for the
prevention and treatment of mastitis (Ryan et al., 1998, 1999; Crispie et al., 2008;
Klostermann et al., 2008; Beecher et al., Frola et al., 2012).

In our recent studies, a preparation of SF68 was used to substitute for the
commercial antibiotic dry cow formula in Holstein cows and was found
with extra benefits of enhancing the local innate immune function (Peng
et al. 2013) and accelerating the involution process (Tiantong et al. 2014)
of mammary gland during the acute phase of drying-off.

METERIALS AND METHODSCow selection and management
Lactating, second parity Holstein cows at 24 - 56 months of age were raised at the
University Farm of National Chung Hsing University (Taichung, Taiwan).
Milk stasis was practiced when cows were reaching the final two months of pregnancy.
Milk yield was less than 5 kg/day.
The experimental procedures have been approved by the committee of Care and Use of
Agriculture Animals of the university.

Figure 8 Summarized result of
two individual neonatal calves
showing the blood total leukocyte
count and function, plasma total
protein content and composition
of gamma-globulin and albumin,
and plasma MMP-2 level.
The most prominent change observed in the current study in association with intramammary
SF68 infusion is the elevation of MMP-2 level, both systemic and local mammary gland.
The presence of MMP in animal tissues and fluids has been used as supplementary information
for diagnosing diseases monitoring organ remodeling, including horse arthritis (Jouglin et al.,
2000), cow mastitis (Rabot et al., 2002) and different stages of mammary gland involution (Yu et al.,
2012).
The higher MMP-2 level in plasma and colostrum is very likely related to some subclinical
proinflammation in the body and mammary gland.
No change in most of the conventional physiological parameters of experimental cows during
the nearly two-month period following SF68 infusion.
Regarded clinically normal of final stage of pregnancy, the parturition, the colostrum quality
and the neonatal calves of Holstein cows after intramammary SF68 infusion.
Higher levels of the novel proinflammatory index MMP-2 in cow plasma and initial colostrum
associated with SF68 infusion might imply subclinical systemic and mammary gland
inflammation.
Lower casein composition in the initial colostrum might reveal suboptimal mammary
synthetic capacity at partum, and, therefore, warrants more investigations.
