“…The level of DMI observed in this experiment is aligned with the level expected for zebu cattle confined under tropical conditions (AZEVÊDO et al, 2016). The lack of effect on intake in response to probiotic supplementation was also observed by other authors (GHORBANI et al, 2002;KEYSER et al, 2007;KELSEY & COLPOYS, 2018) Weights and daily average gain in each phase and total are presented in Table 2. No statistical differences were observed for the effect of treatments on the weights performed over the experimental period.…”

“…It is observed that the use of TCP improved the feed conversion of feed into product by 12.6%. Kelsey & Colpoys (2018) used a probiotic containing strains of Enterococcus faecium, Lactobacillus acidophilus, Lactobacillus casei, and Lactobacillus plantarum and found that weaned calves receiving dietary probiotics had greater ADG and feed efficiency compared with those that did not receive probiotics. Improved performance may be partially explained by the probiotics benefits of increasing feed digestibility, preventing excess of lactate production and improving ruminal fermentation (SEO et al, 2010).…”

SUMMARY The objective of this study was to evaluate the effect of probiotic consortium on feed intake, feeding behavior, feed efficiency, fecal score, weight gain and carcass traits in finishing Nellore heifers fed high energy diets in feedlot. Twenty-four Nellore heifers were distributed in 12 pens with two animals each, being six pens per treatment. In the control treatment (CON) the animals were fed exclusively with the base diet, which contained 35% corn silage and 65% concentrate. In the treatment with probiotic consortium technology (TCP), the animals received the base diet and a single dose of 75 mL/animal/day of Bio Ciclo Completo (Global Saúde Brasil) top-dressed in the morning feeding. There was no period of adaptation to the diet. The experiment lasted 93 days. The use of TCP did not affect (P = 0.980) the dry matter intake. The average daily gain was 12.5% greater (P = 0.025) in the animals treated with TCP (0.941 kg/day for TCP versus 0.834 kg/day for CON). The animals that received TCP improved (P = 0.021) the feed efficiency by 12.6%. The animals that received TCP tended to have a better (P = 0.094) fecal score within the first 27 days of feedlot. There were no significant effects of TCP on the feeding behavior and carcass traits. Based on the results, there is a great potential of using TCP to improve productivity in beef cattle.

“…However, there has been great concern about the use of antibiotics which may result in antibiotic resistant pathogens, posing a potential risk of exposure for humans and calves [3]. The use of antibiotic in the feed of livestock was banned in European Union from 2006 and in China from July 1, 2020.…”

Objective: The aim of this study was to investigate the effects of dietary supplementation with a multi-strain probiotic (MSP) product containing of Bifidobacterium animalis, Lactobacillus casei, Streptococcus faecalis, and Bacillus cerevisiae on growth, health, and fecal bacterial composition of dairy calves during the first month of life.Methods: Forty Holstein calves (24 female and 16 male) at 2 d of age were grouped by sex and date of birth then randomly assigned to 1 of 4 treatments: milk replacer supplementation with 0 g (0MSP), 2 g (2MSP), 4 g (4MSP), and 6 g (6MSP) MSP per calf per day.Results: Supplementation of MSP did not result in any significant differences in parameters of body measurements of calves during the 30 d period. As the dosage of MSP increased, the average daily gain (p = 0.025) and total dry matter intake (p = 0.020) of calves showed a linear increase. The fecal consistency index of the 2MSP, 4MSP, and 6MSP group calves were lower than that of the 0MSP group calves (p = 0.003). As the dosage of MSP increased, the concentrations of lactate dehydrogenase (p = 0.068) and aspartate aminotransferase (p = 0.081) in serum tended to decrease, whereas the concentration of total cholesterol increased quadratically (p = 0.021). The relative abundance of Dorea in feces was lower (p = 0.011) in the 2MSP, 4MSP, and 6MSP group calves than that in the 0MSP group calves. The relative abundance of Dorea (p = 0.001), Faecalibacterium (p = 0.050), and Mitsuokella (p = 0.030) decreased linearly, whereas the relative abundance of Prevotella tended to increase linearly as the dosage of MSP increased (p = 0.058).Conclusion: The MSP product can be used to reduce the diarrhea, improve the performance, and alter the composition of the fecal bacteria in neonatal dairy calves under the commercial conditions.

“…These probiotics can regulate the balance of gut microbes, promote the growth and productivity of animals and improve host resistance to diseases [ 3 ]. To this end, they have been extensively used in dairy cattle [ 4 ], beef cattle [ 5 ], pigs [ 6 ], hens [ 7 ] and rabbits [ 8 ]. Postbiotics are defined as soluble products or metabolites secreted by probiotics that have physiological benefits to the host [ 9 ].…”

The aim of this study was to evaluate the effect of lactic acid bacteria-based postbiotic supplementation on semen characteristics and hematological and biochemical profiles in rabbits. A total of 28 males were randomly allocated into two groups. Males received a Control diet and Enriched diet supplemented with postbiotic for 15 weeks (4 weeks of adaptation period and 11 weeks of experimental period). Body weight, feed intake and semen characteristics were recorded weekly. Hematological profile was recorded at the beginning and end of the experiment and biochemical profile at 0, 5, 10 and 15 weeks. Bayesian methodology was used for the statistical analysis. Feed intake was higher in Control diet (125.2 g) than in the Enriched diet (118.6 g, p = 1.00). The percentages of abnormal spermatozoa were higher in Control diet than in Enriched diet (30% and 22%; p = 0.93) and the acrosome integrity percentage was lower (97% and 96%; p = 0.87). The hematological profile was within the range for healthy rabbits. The plasmatic level of alanine aminotransferase was higher in Control diet than Enriched diet at 5 and 10 weeks (p = 0.93 and p = 0.94, respectively) and alkaline phosphatase was similar in Control diet throughout the experiment, but decreased in Enriched diet (p = 0.97). No difference was found in kidney parameters (uric nitrogen and creatinine). Enriched diet showed higher total protein and globulin than Control diet (p = 0.99). Phosphorus was lower (p = 0.92) in Control diet than in Enriched diet. In conclusion, the addition of the postbiotic based on lactic acid bacteria seems to improve the quality of the semen and the liver profile in rabbits.
