“…In our study, the genus of Ruminococcaceae UCG-005 increased both in calves with and without dam when they grew up. Chen et al (2020) reported that Ruminococcaceae UCG-005 had the highest abundance in feces of calves fed pasteurized milk and acidified milk on 90 days, which would improve the fiber utilization ability of calves. In addition, the increased abundance of Ruminococcaceae UGG-005 (phylum Firmicutes) may again confirmed the important role of Firmicutes in the gastrointestinal tract.…”

In pastoral areas and semi-agricultural and semi-pastoral areas of Sichuan, beef cattle breeding mode is mainly dependent on nature to raise livestock. On the one hand, owing to the shortage of forage grass in spring, cows suffer from malnutrition. On the other hand, competition for milk between human and livestock further deepens the malnutrition of newborn calves, and the mortality rate even exceeds 40%, resulting in serious waste of beef cattle source resources. The objective of this study was to investigate the effect of different cultivation methods (calves with and without dam) and age on calves hindgut microbiome. Sixteen healthy calves (Yak ♂ × Pian cattle ♀, with similar birthday 0 ± 2 d and body weight 13.1 ± 1.13 kg), were selected and randomly divided into two groups. The control group was cultivated with heifers, whereas the treatment group was cultivated without heifers and was fed milk replacer during the whole 95 days formal experimental period. Fecal samples were collected on 35, 65 and 95 days of age for high-throughput sequencing. The α-diversity was different between the two groups on day 35; however, the bacterial species richness and diversity was almost not different on day 95. Principal coordinates analysis revealed significant difference between the two groups on all the three time points, and the timepoints of day 65 and 95 were closer and separated from the timepoints of day 35 in calves with dam, whereas the timepoints of day 35 and 65 were closer and separated from day 95 in calves without dam. As time passed, the abundance of Firmicutes increased, while Proteobacteria and Actinobacteria decreased in calves with dam. But in calves without dam, the abundance of Bacteroidetes and Proteobacteria increased on day 65 and then decreased on day 95. In genus level, the relative abundance of Bacteroides decreased in calf with dam while its abundance increased first and then decreased in calf without dam but both resulted in the range of 3.5~4.5%. The relative abundance of Lactobacillus decreased, whereas Ruminococcaceae UCG-005 increased in both groups as the calf grew up. It was concluded that the richness and evenness of the microbial communities was higher in calves with dam than without dam, and a stable gut microbiome in calve with dam is established earlier than calf without dam.

“…Lower pH values are optimal for digestive enzymes and thus improve nutrient digestibility, which leads to the higher body weight (b.w.) gains in animals supplemented with acidifiers ( 5 ). The digestive tract of the young calf is deficient in proteolytic and amylolytic enzymes, and that is why they are broadly used in animal feeding to support the pancreatic secretory function.…”

Introduction The rearing of calves is a difficult period for farmers due to health problems to which the animals are prone this time. Since the use of antibiotics as growth promoters has been forbidden, various innovative feed additives have been tested in many countries around the world. Material and Methods In this study, experimental (E) calves were supplemented with a novel feed additive consisting of the pancreatic-like enzymes protease and lipase, a fat-coated mixture of organic fumaric, malic, citric and sorbic acids, sodium butyrate and silicon dioxide nanoparticles. Control (C) calves received feed without additive. During the supplementation, white blood cell (WBC) counts with leukocyte differentiation, percentages of B lymphocytes and T lymphocytes and their subpopulations, phagocytic activity and oxidative burst of circulating monocytes and granulocytes were examined. Body weight (b.w.) gains of the calves were also monitored. Results The WBC counts in the E and C calves were within the reference ranges throughout the study. In the analysis of the percentages of the lymphocyte subpopulations, phagocytic activity and oxidative burst, no statistically significant differences were reported between the E and C groups. However, higher average daily body weight gains were obtained for the E calves. Conclusion The study revealed that the examined feed additive did not modulate the immune response of the calves significantly. The tendency to higher daily average b.w. gains in the E calves than in the C calves suggests a beneficial effect of this feed additive.

“…This method is a viable option to increase the shelf life of milk without altering its nutritional benefits (Anderson, 2008). Some studies have reported that feeding acidified milk or acidified milk replacer to calves led to improved weight gain and better fecal scores, which are good indicators of calf growth and development ( Li et al, 2019 ; Chen et al, 2020 ). However, further studies are needed to demonstrate improved health and performance when calves are fed acidified milk or acidified colostrum.…”

Graphical Abstract Summary: Diarrhea is a leading cause of death in preweaning calves. Acidification of colostrum is an effective tool in colostrum management. The goal of this study is to investigate the effect of feeding acidified colostrum to calves at birth on fecal microbiota during the preweaning period compared with calves fed nonacidified colostrum. Findings of this study indicated a considerable flux in the calf microbiome through the neonatal period and weaning transition. Feeding calves with acidified colostrum induced changes only in a few fecal bacteria but allowed for early colonization of Faecalibacterium compared with control calves. Faecalibacterium is a butyrate-producing bacterium that is associated with decreased diarrhea and improved growth in calves.
