Effect of Enterococcus faecium SF68 on growth performance and in vivo digestibility in buffalo calves
The effect of dietary supplementation with Enterococcus faecium strain SF68 on growth performance, faecal consistency and in vivo digestibility in buffalo (Bubalus bubalis) calves was evaluated. Forty calves were randomly assigned at 10 d of age to one of four treatments: (A) milk replacer with no additive, (B) milk replacer supplemented with 0.17 g/l of viable (2 x l09 cfu/g) E. faecium bacteria daily for 3 days with an interval of 7 days throughout 11 weeks, (C) milk replacer supplemented with E. faecium daily for 4 weeks, (D) milk replacer supplemented with E. faecium daily for 11 weeks. A total mixed ration was offered ad libitum from 5th week of the experimental period. Faecal score was significantly better in E. faecium-treated calves than control ones. The use of E. faecium had no effect on average daily gain at any stage, total body weight (BW) gain, dry matter intake or total tract digestibility. Therefore, E. faecium supplementation may be able to act favourably on the health of the gastro-intestinal trac

Fatty acid composition of Mediterranean buffalo milk fat
The purpose of this research was to investigate the variation in fatty acid composition of milk fat from four buffalo (Bubalus bubalis) herds under different feeding management and ration composition. Changes in milk fatty acid composition were monitored on a weekly basis. Saturated fatty acids (65.5%) predominated in buffalo milk fat; monounsaturated and polyunsaturated fatty acids were 27.0% and 4.5%, respectively. Of saturated fatty acids, the content of palmitic acid was the highest (30.6%) followed by stearic acid (12.0%) and myristic acid (10.7%). Of the unsaturated fatty acids the content of oleic acid was the highest (26.6%). The average content of conjugated linoleic acid (0.76±0.33) was higher than the maximal values generally reported for dairy cow

Effect of Lupinus albus as protein supplement on yield, constituents, clotting properties and fatty acid composition in ewes' milk
The effect of feeding lupin seeds (Lupinus albus L.) as an alternative protein source in ewe diets was investigated. Two groups of 18 Sarda ewes were fed two different isonitrogenous diets: with lupin (L) seed, given after 12 h soaking, or soybean meal (SBM) as the main protein source. DMI, variations of body weight and milk production were unaffected by the treatment. Although not statistically significant, in the group fed L diet the production of milk fat and protein was higher. Clotting properties of milk were similar for the two treatments, probably due to the small differences in the milk protein contents. The fatty acid profile of milk was affected by treatment with a larger content of short (14.19 wt% versus 12.26 wt%)- and medium (49.37 wt% versus 47.76 wt%)-chain fatty acids in milk from ewes fed the L diet. CLA content was unaffected by treatment. Triglyceride content of fat from the two diets reflects the milk fatty acid composition. Indeed, milk from L diet showed a higher level of medium-chain triglycerides, which are of particular interest to consumers with concerns over health and heart disease. The inclusion of lupin seed in the diet of lactation ewes can be a means of achieving a more desirable triglyceride profile in milk fat. Milk with enhanced nutritive quality may promote wider market penetration of sheep dairy products
Plasma disposition, concentration in the hair, and anthelmintic efficacy of eprinomectin after topical administration in donkeys
Objective-To investigate plasma disposition, concentration in the hair, and anthelmintic efficacy of eprinomectin after topical administration in donkeys. Animals-12 donkeys naturally infected with strongyle nematodes. Procedures-The pour-on formulation of eprinomectin approved for use in cattle was administered topically to donkeys at a dosage of 0.5 mg/kg. Heparinized blood samples and hair samples were collected at various times between 1 hour and 40 days after administration. Samples were analyzed via high-performance liquid chromatography with fluorescence detection. Fecal strongyle egg counts were performed by use of a modified McMaster technique before and at weekly intervals for 8 weeks after treatment. Results-Plasma concentration and systemic availability of eprinomectin were relatively higher in donkeys, compared with values reported for other animal species. Concerning the anthelmintic efficacy against strongyle nematodes, eprinomectin was completely effective (100%) on days 7 and 14 and highly effective (> 99%) until the end of the study at 56 days after treatment. No abnormal clinical signs or adverse reactions were observed for any donkeys after treatment. Conclusions and Clinical Relevance-Eprinomectin had excellent safety. The relatively high plasma concentration after topical administration could result in use of eprinomectin for the control and treatment of parasitic diseases in donkeys
Feeding management and milk production in organic and conventional buffalo farms
The feeding management, milk yield and milk composition were investigated in two adjacent buffalo farms, one organic certified (on average, 220 lactating buffalo cows) and one conventional (on average, 314 lactating buffalo cows) located in the Sele Plain (southern Italy). Milk samples from the two farm were collected twice a month during the period from June to November 2006. Milk production was also recorded. The investigated milk components were the content of protein, fat, lactose, urea and the number of somatic cells. The following features about the feeding management of lactating buffalo cows were recorded during monthly farm visits: feed used, herbage utilization, ration composition. Fat and protein correct milk yield was higher in conventional farm than in organic one, but milk components were similar between the farms. The greatest differences were found in the somatic cell count, lower in organic milk than in conventional one, and the urea content, which was higher in organic milk than in conventional farm, but still within the normal range reported for buffalo milk
Efficacy of eprinomectin pour-on against Dictyocaulus arnfieldi infection in donkeys (Equus asinus).
A trial to assess the efficacy of eprinomectin (EPM) against the lungworm Dictyocaulus arnfieldi was carried out on 15, naturally-infected donkeys. Ten animals were treated with a 'pour-on' EPM preparation (at a dose of 0.5mg/kg bodyweight), and five animals acted as controls. EPM was 100% effective in eliminating faecal larvae from day 7, until the end of study at day 28. No adverse drug-reactions or side-effects were observed in any of the treated donkeys
Validation of Two Commercial Multiplex Real-Time PCR Assays for Detection of SARS-CoV-2 in Stool Donors for Fecal Microbiota Transplantation
Recurrent infection by Clostridioides difficile has recently been treated by fecal microbiota
transplantation (FMT). As viable SARS-CoV-2 was recovered from stool of asymptomatic individuals,
the FMT procedure could be a potential risk of SARS-CoV-2 transmission, thus underlying the
need to reliably detect SARS-CoV-2 in stool. Here, we performed a multicentric study to explore
performances of two commercially available assays for detection of SARS-CoV-2 RNA in stool of
potential FMT donors. In three hospitals, 180 stool samples were spiked with serial 10-fold dilutions of
a SARS-CoV-2 inactivated lysate to evaluate the Seegene Allplex â„¢ SARS-CoV-2 (SC2) and SARS-CoV-
2/FluA/FluB/RSV (SC2FABR) Assays for the detection of viral RNA in stool of FMT donors. The
results revealed that both assays detected down to 2 TCID50/mL with comparable limit of detection
values, SC2 showing more consistent target positivity rate than SC2FABR. Beyond high amplification
efficiency, correlation between CT values and log concentrations of inactivated viral lysates showed
R2 values ranging from 0.88 to 0.90 and from 0.87 to 0.91 for the SC2 and SC2FABR assay, respectively.
The present results demonstrate that both methods are highly reproducible, sensitive, and accurate
for SARS-CoV-2 RNA detection in stool, suggesting a potential use in FMT-donor screening
