“…As previously reported, improved feed efficiency and growth performance were observed by probiotics when mixed with milk replacer (Frizzo et al 2011;Novak et al 2012). The majority of milk or milk replacer bypasses the rumen and reticulum through the closure of the esophageal groove, which allows these dairy-based liquid feeds to be digested in the abomasum in a much more efficient manner.…”

The objective of this study was to assess the effect of dietary probiotics on rumen fermentation and the bacterial community in dairy calves. Twelve Holstein calves were randomly allocated to three treatments: a basal diet, the basal diet supplemented with Lactobacillus plantarum GF103 (LB) or basal diet supplemented with a mixture of Lactobacillus plantarum GF103 and Bacillus subtilis B27 (LBS). A milk replacer was fed to calves from 8 days of age. A starter and alfalfa hay was offered ad libitum from 21 and 28 days of age, respectively, and the orts were weighted daily. The ruminal fluid was sampled at 56 and 83 days of age to determine the rumen fermentation characteristics. The bacterial community was analyzed by denaturing gradient gel electrophoresis (DGGE) and the number of certain bacteria was quantified by real-time polymerase chain reaction. The ratio of total dry matter intake to average body wieght was higher in the control (P < 0.05). The DGGE fingerprint of the 16S ribosomal RNA gene was affected by the blended probiotics at 83 days of age. The number of Ruminococcus albus was lower in the LB and LBS treatment (P < 0.05). Oral administration of the probiotics affected the rumen bacterial community and the numbers of cellulolytic bacteria decreased.

“…Heinrichs et al (2003) reported that lymphocytes tended to increase in the synbiotic group as compared to control and other groups in weaned piglets. Similarly, Frizzo et al (2011) and Agazzi et al (2014) reported no significant effect of feeding probiotic on lymphocyte count in calves. On the contrary, Roodposhti and Dabiri (2012) found no significant difference in lymphocyte count in calves belonging to the probiotic, prebiotic, synbiotic and control groups.…”

“…The antibiotic residues and resistance forced researchers to look for alternatives to antibiotics. The use of probiotics (Frizzo et al, 2011, Kim et al, 2011, prebiotics (Konstantinov et al, 2004) and their combination (synbiotics) came up as a safer alternative to antibiotics (Heinrichs et al, 2003). Supplementation of probiotics causes an increase in a number of nonpathogenic bacteria which leads to competition between pathogenic and nonpathogenic bacteria (Donald et al, 2002) thus reducing the incidence of calf scours and mortality.…”

A study was conducted to evaluate the impact of probiotic, prebiotic and synbiotic as feed additives on faecal counts of coliform and E. coli along with cell mediated immune response in crossbred calves. For this purpose fifteen days old, 24 crossbred calves were divided into 4 groups of 6 calves each. The calves were assigned to different dietary treatments viz T 0 (control group) -basal diet, T 1 (probiotic group) -basal diet + Lactobacillus acidophilus @ 1 g/calf/day (2 x 10 10 cfu/ g), T 2 (prebiotic group) -basal diet + Mannan oligosaccharide (MOS) @ 4 g per calf/day and T 3 (synbiotic group) basal diet +Lactobacillus acidophilus @ 0.5 gm (2 x 10 10 cfu/ g) + 2 g MOS per calf/day respectively for a period of 90 days. Faecal samples for coliform and E. coli count were taken at 15 days interval. Blood samples were taken at 15 days interval for lymphocyte count. Blood samples were taken at 45 th and 90 th -day for lymphocyte stimulation test (LST) in EDTA coated vials. Skin fold test was done on 90 th day of experimental study. The results of study showed that there was a significant reduction in faecal shedding of coliform and E. coli in T 1 , T 2 and T 3 groups indicating lesser proliferation of pathogenic bacteria in the gut. The treatment groups T 2 and T 3 showed a significant increase in lymphocyte count whereas all the treated groups had significantly higher values of the lymphocytic index on 45 th and 90 th day post supplementation indicating improved cell mediated immunity. Increased skin fold thickness was observed post 48 hours of phytohaemagglutinin injection in T 2 and T 3 groups. It may, therefore, be concluded that supplementation of prebiotic and synbiotic is advantageous in attaining gut conditioning and enhanced immunity which may be helpful in preventing calf scours in crossbred calves.

“…Many studies have focused on the effect of probiotic applications on growth performance and animal health (Timmerman et al 2005;Frizzo et al 2010). A meta-analysis conducted by Frizzo et al (2011) showed that probiotics increase body weight gain and improve feed efficiency. Recent research has demonstrated that the effects of probiotic bacteria can reach far beyond the gastrointestinal tract.…”

ABSTRACT:In order to improve the gut microbiome of calves, probiotic bacteria can be fed as active livingcells (fermented milk), or as live but inactive (freeze-dried) cultures. Ten bifidobacterial strains with suitable probiotic properties (as determined in our previous study) were tested for survival during the freeze-drying process, and screened for their ability to ferment cow's milk. The viability of both freeze-dried and live-cell cultures during storage was also tested. All of the strains tested were able to ferment cow's milk, with average counts of 8.26 ± 0.62 log CFU/ml. Eight out of the ten strains were able to survive in milk for 2 months in counts higher than 10 6 CFU/ml. Bifidobacteria showed high viability following the freeze-drying process, with average numbers of 9.03 ± 0.22 log CFU/vial and did not decrease after 12 months of storage. The mixture of rifampicin-resistant variants of bifidobacteria (RRBs) was fed to 2-day-old dairy Charolais calves in the form of living-cells, or as freeze-dried bacteria. The control group was given no probiotics. Survival of the RRBs administered and the numbers of other bacterial groups in faecal samples was monitored by culturing. Bifidobacteria that were administered passed successfully through the upper parts of the gastrointestinal tract, and were found in numbers higher than 10 9 CFU/g for two weeks. RRBs colonized the intestines of calves for at least 63 days in both treatment groups. Significantly higher total counts of bifidobacteria were found in the treated groups, compared to the control group. Reduction in Escherichia coli and total coliforms numbers, and an increase in lactobacilli counts were observed in both experimental groups following the application of the probiotic mixtures. Our results show that both forms of administering probiotic bifidobacteria to calves are effective, but that the freeze-dried form is more suitable from a practical viewpoint.
