Effects of dietary feed supplementation of heat-treated <i>Lactobacillus sakei</i> HS-1 on the health status, blood parameters, and fecal microbes of Japanese Black calves

This study investigated the effect of heat-killed Lactobacillus sakei HS-1 (HK-LS HS-1) on the health and fecal bacteriological change of suckling Japanese Black calves as a supplement in milk replacers. Twelve calves were separated from dams to calf-hatch after calving for milk replacers feeding. They were randomly assigned to an HK-LS HS-1 supplement or a control without HK-LS HS-1 group in milk replacers. HK-LS HS-1 was administered from separation day to 3 weeks. Blood and fecal samples were examined. Two calves with a haptoglobin concentration of >500 µg/ml on day 0 were excluded from the experiment, and 10 calves were finally included. Glucose and vitamin A levels on day 7 were significantly higher (P<0.05) in the supplement group than in the control group. No significant differences were observed in haptoglobin or serum amyloid A between the groups. The number of Escherichia coli in feces was lower in the control group than in the supplement group on day 21 (P=0.06). No difference was observed in the number of bifidobacteria, but that of lactic acid bacteria was significantly higher (P<0.05) in the supplement group on day 21. The number of medications administered was significantly lower (P<0.05) in the supplement group (5.2±3.9) than in the control group (10.6±5.9) during the experimental period. The results indicated that HK-LS HS-1 is potentially beneficial for improving intestinal microbes and reducing the number of medical treatments.

“…First systematic investigations on the development of bacteria in the gut of newborn calves were carried out in the early 1960s (Smith and Crabb 1961;Smith 1965). Although there are some publications dealing with the calf's intestinal microbiome, there are only a few studies that cover the development within the first week of life (Takino et al 2017;Song et al 2018). This is surprising, considering that enteric infections in neonatal calves are amongst the major causes of calf mortality during the early stage of life (Bendali et al 1999).…”

Development of selected bacterial groups of the rectal microbiota of healthy calves during the first week postpartum

Aims:The intestinal microbiota of newborn calves is largely unexplored even if it is of great significance for their future health. Therefore, the aim of the study was to gain a better insight into the development dynamics of certain bacterial groups during the first week of life. Methods and Results: Faecal samples of healthy Simmental calves (dualpurpose breed; n = 80), bottle fed and raised in a dairy farm were taken immediately after birth and at 6/12/24/48/72/168 h (h) after birth. Samples were analysed using cultural, biochemical and molecular-biological methods. The aerobe, anaerobe, Enterobacteriaceae and Enterococcus counts of healthy calves increased significantly between 6 and 24 h postpartum (P <0Á05). Apart from the anaerobes, bacterial counts decreased after reaching a plateau at 24-48 h. Enterococcus faecalis was detected in significantly higher counts compared to E. faecium (P <0Á05). Lactobacilli developed more slowly and increased until day 7 after birth to a mean value of 6Á8 9 10 7 CFU per g. MALDI-TOF analysis of 2338 lactobacilli isolates resulted in 36 different species. Conclusions: Lactobacillus reuteri became the most common Lactobacillus sp. during the first week of life. Significance and Impact of the Study: This fact seems to be very important for the calf's intestinal health because L. reuteri is known to show in vitro bactericidal effects against bacterial pathogens and anti-infective activities against rotaviruses and Cryptosporidium parvum.

“…When meconium peritonitis occurs, early operation is a valid way to prevent the exacerbation of intra-abdominal inflammation, hyperemia and edema of the intestinal wall and intestinal adhesion, assisting in the reduction of severe infection and mortality. Takino T et al [13] pointed that the relative abundance of Firmicutes (including its families, such as Lactobacillaceae ), which supports health and immune function, was increased substantially during the first week after birth. Giri P et al [12] observed that the sympathoadrenal function could be affected by lack of a microbiome or microbial metabolites, leading to inferior health status.…”

BackgroundIn the last century, meconium peritonitis(MP)was once a highly fatal gastrointestinal. disease With the development of fetal radiological technology, abnormal signs, such as pseudocysts, can. be detected during the fetal period so that more patients can be diagnosed prenatally and receive surgery. in the early stage of life. The survival rate of MP has increased up to 80% in recent years. According to. a review of the treatment and outcomes of patients diagnosed with MP, we evaluated the influence of. early operation on survival rate and discussed the risk factors of prognosis.MethodsWe collected 79 cases of patients diagnosed with MP who were treated in our department. from October 2001 to December 2017. They were divided into 2 groups. Patients in group A were born. in our hospital. Patients in group B were born in a local hospital with suspicion of MP and then transferred. to our department.ResultsThe birth weight (BW) and gestational age (GA) of patients were higher in group A than in. group B. There was no significant difference in the proportion of premature and low birth weight (LBW). patients between the two groups (p = 0.422, p = 0.970). Their age at the time of surgery was younger in. group A than in group B (1.4 ± 2.0 vs. 6.9 ± 14.9, p < 0.001). The overall survival rate of group A was higher. than that of group B (95.0% vs. 79.5%, p = 0.038). The prognosis of premature patients was worse than. that of full-term infants for both groups (p = 0.012).ConclusionsPrematurity is a significant risk factor related to death for MP patients. The survival rate. of MP patients can be improved by early operation during the neonatal period.
