“…This exploratory approach allowed us to anticipate an ABU pattern based on the production system adopted by the farms in northern and southern Vietnam. The relationship between the production system and ABU in Vietnam has been explored before (Kim et al, 2013;Luu et al, 2021). But to our knowledge, this is the first study to explore the association between farming practices (as a group or by individual variables) and patterns (which group several variables associated with each other) of ABU in northern and southern Vietnam.…”

“…In Vietnam, three or four types of chicken production systems are usually described (backyard, semi-intensive and intensive farms) (Burgos et al, 2007;Desvaux et al, 2008;Duc and Long, 2008), but more complexity may be required to properly describe chicken farming diversity. Previous studies have determined heterogeneity in the amounts of antimicrobials used in different systems (Carrique-Mas et al, 2015) and in practices surrounding their usage (Kim et al, 2013;Luu et al, 2021). However, few studies have compared the usage between the 3 production systems at the same time.…”

“…Concerns about the use of antimicrobials in animal husbandry extend to its use as a growth promoter, especially when there is a discussion about its routine administration and in sub-doses. The incorrect and uncontrolled use of antimicrobials, in addition to leading to increased resistance, altering metabolic pathways, and impairing the integrity of the human, animal, and environmental microbiota, leads to inefficiency of these molecules ( Tyrell et al., 2019 ; Luu et al., 2021 ). Some studies of antimicrobial resistance surveillance have already found genes of clinical importance along pig husbandry samples.…”

Antimicrobial resistance is a major threat to public health. Antimicrobial use in animal husbandry is a major concern since it can favor an increase in antimicrobial resistance among farms. Herein, we aim to better understand and characterize the main resistome profiles in microbial communities found in pig farms. Sampling of swine manure was performed in two different timepoints (October 2019 and January 2020) in each of the 14 different swine farms, located in the mesoregion of Western Santa Catarina state in Brazil, a pole of swine product production of worldwide importance. Samples were divided into three groups: farms with the opened regimen and no usage of antimicrobials (F1; n = 10), farms with the closed regimen and usage of antimicrobials (F2; n = 16), and farms with the closed regimen and no usage of antimicrobials (F3; n = 2). The metagenomic evaluation was performed to obtain and identify genetic elements related to antimicrobial resistance using nanopore sequencing. We used ResistoXplorer software to perform composition, alpha and beta diversity, and clustering analysis. In addition, PCR reactions were performed to confirm the presence or absence of seven different beta-lactamase family genes and five phosphoethanolamine transferase gene variants clinically relevant. Our findings based on the identification of resistance genes at the mechanism level showed a prevalence of alteration of the drug target (72.3%) profile, followed by drug inactivation (17.5%) and drug efflux (10.1%). We identified predominantly aminoglycosides (45.3%), tetracyclines (15.9%), and multiclass (11,2%) resistance genes. PCoA analysis indicates differences between F1 and F2 profiles. F2 samples showed increased diversity when compared to the F1 group. In addition, herein we first report the identification of mcr-4 in a slurry sample (C1F1.1) in Santa Catarina State. In general, our findings reinforce that many factors on the practices of animal husbandry are involved in the resistome profile at the mechanism and class levels. Further studies to better understand microbiome and mobilome aspects of these elements are necessary to elucidate transmission pathways between different bacteria and environments.

“…The issue of achieving planned indicators of reproductive qualities is acute for veterinary specialists [3]. Currently, many methods and means have been developed that contribute to achieving the target indicators of reproductive and productive qualities of pigs, but only a part of them are produced by industry and is available on the commercial market; the efficiency of preparations available to the consumer is not always sufficient, the expediency of their use is often not economically justified [4,5]. In the light of the above, it seems promising to develop, test and introduce new therapeutic and preventive means into practical veterinary medicine; such means ensure the preservation of health, the realization of productive and reproductive qualities of animals, the use of which would be economically feasible [6,7].…”

The purpose of this work was to realize the reproductive qualities of sows and the productivity of young pigs with immunotropic preparations PigStim-C and PigStim-M. To set up the experiment, 30 heads of nursing sows were selected on the 15th day after the first farrowing. The selected sows were divided into 3 groups according to the breed, reproductive qualities and reproductive health according to the principle of pairs of analogues. It was found that intramuscular injection of the immunotropic drug PigStim-C to animals of the 1st experimental group (and PigStim-M to animals of the 2nd experimental group) at a dose of 5 ml per head on the 15th, 20th, and 25th day after farrowing contributes to: reducing the period from weaning to coming into heat and the onset of the optimal period for insemination by 4.5-9.1%; an increase in the success of insemination from 90% in the control group to 100%; an improvement in sows’ prolificacy by 8.1-8.6% and a decrease in the number of stillborn piglets by 16.7-33.3%; a decrease in the number of sows with prolonged farrowing by 2-3 times resulting in a decrease in the occurrence of postpartum pathologies of reproductive organs, such as metritis-mastitis-agalactia syndrome, as well as an increase in the therapeutic measures' efficiency in case of their occurence; a decrease in the disease incidence of young pigs obtained from these sows during the next farrowing by 36.8-41.5%, an increase in their viability by 1.45-2.97% and an increase in live weight at the end of the growing period by 0.16-0.18 kg, rearing – by 1.1-1.22 kg, and when removed from fattening – by 3.6-4.0 kg.
