Background Due to the tendency to reduce antibiotic use in humans and animals, more attention is paid to feed additives as their replacement. Crucial role of feed additives is to improve the health status, production efficiency and performance. In this original research, we estimate the potential influence of garlic (Allium sativum) extract and probiotic formula including Enterococcus faecium, Lactobacillus rhamnosus and Lactobacillus fermentum on the intestinal microbiota of sows, using the next generation sequencing method (NGS). Results Our results indicate that the overall species richness as well as the composition of swine gut microbiota may be shaped by regular feeding with supplemented additives. On the Family and Genus level both additives (garlic extract and probiotics) seem to decrease microbiome diversity and richness. However, when it comes to garlic supplementation, we found the opposite trend on the Species level. Conclusions The analysis of the selected microbial function indicates that both additives used in this study (garlic extract and composition of probiotics) seem to create a greater metabolic potential than estimated in a control group of sows. A general trend of losing or decreasing members of pathogenic species in the swine microbiome seems to occur in relation to both supplemented additives. In the prevention of some bacterial diseases supplemented additives could be considered for future use.
The present study aimed to evaluate the influence of a garlic extract and probiotic strains, Enterococcus faecium, Lactobacillus rhamnosus and Lactobacillus fermentum, on sows and their offspring. A total of 24 sows and the 301 piglets they farrowed were used in this trial. The animals (sows and piglets) were assigned to 3 groups: group A, supplemented with garlic extract; group B, supplemented with probiotics; and the control group C, without supplementation. The trial lasted from the 80th day of gestation to the weaning day for sows. For piglets, results were analyzed during two periods, from the 8th day to the 56th or the 147th day of life, in order to determine the more desirable duration of supplementation. Morphological and biochemical blood parameters, as well as body weight and piglet losses, were recorded. At weaning, the piglets supplemented with probiotics were heavier than the rest of experimental population (P ≤ 0.01). On the day of sale for slaughter, the pigs from the control group were on average 15 kg lighter (P ≤ 0.01) than those from both supplemented groups. Differences in blood parameters were also noted between the groups. Our findings suggest that the use of a garlic extract and probiotic bacteria may help improve pig performance at various stages of the production cycle.
The human microbiome in terms of the number of bacteria exceeds the number of cells in the human body. It is defined as an additional "forgotten organ" and plays a key role in maintaining a high health status, which is conditioned by the maintenance of certain proportions and natural relations between bacteria and cells of the host organism. New diagnostic methods can enable profiling not only the human microbiome, but also livestock. An innovative analytical method, which is next generation sequencing (NGS), is increasingly used in the study of the microbiome. Many bacteria are referred to as "uncultivated" or "non-culturable" and metagenomics has played an important role in detecting these bacteria and has contributed to the development of new media for their cultivation. The main application of NGS in microbiology is to replace the conventional characterization of pathogens based on the assessment of morphology, staining properties and metabolic traits with their genome related characteristics. There are several platforms i.e. "diagnostic tools" that use a variety of DNA sequencing technologies, among others Ion Torrent Personal Genome Machine (PGM), Pacific Biosciences (PacBio) and Illumina MiSeq. In the case of swine microbiome, studies of the microbiome with the use of modern sequencing technologies seem to be particularly interesting in the aspect of the upcoming, inevitable changes in preventive and therapeutic procedures in animals. Analyses of this type enable an in-depth assessment of the impact of specific factors on the population of intestinal microbes and learning how to "form" the composition of the microbiome in order to improve the quality of husbandry and to maintain the proper pig’s health status, integrate with the concept of the shared human and animal health.
