Therefore, this study aimed to evaluate the effectiveness of using acidifiers to control Salmonella Typhimurium in 65-day-old pigs by detecting the pathogen in organs at euthanasia. For this, 24 piglets were divided into two experimental groups consisting of 12 piglets each. An untreated control group (G1) and a treatment group (G2) received a liquid organic acidifier in the drinking water for 10 days (D-5 to D5). Five days after the start of treatment (D0), all piglets were challenged with 106 CFU of Salmonella Typhimurium and assessed for 12 days (D12). Every three days (D3, D6, D9, and D12), three animals from each experimental group were euthanized and then submitted for necropsy. Samples from the intestines (ileum, cecum, mesenteric lymph nodes, and ileocolic lymph nodes), liver, spleen, and lungs were collected to isolate Salmonella. The results show that, numerically, Salmonella isolation in the organs of G2 was lower than in G1 and that the number of positive cecum samples in G1 (66.7%; 8/12) was statistically different from the number of positive models in G2 (16.7%; 2/12), with a reduction of 28.6% of the total cecum positive samples in the treated group compared to the control. Therefore, it was observed that the liquid organic acidifier product could reduce the colonization of organs by Salmonella Typhimurium.

This study used a Yucatan black hairless pigs (YBHP) subpopulation to estimate its genetic diversity and population structure. One hundred four adult pigs were selected for the absence of hair, black skin (without spots), black hoof, and straight snout. The porcine-GGP-50K chip was used for SNP genotyping in YBHP, and information on Iberian and Yucatán hairless pigs from the United States (USYU) was taken from databases. All analysis was performed using PLINK v1.9 and v2.1 software. Inbreeding and fixation index values were lower in YBHP, with high observed heterozygosity and allogamy index values, which agree with those obtained in the populations of Canarias and Chato Murciano. According to the clusters generated by the “Genome-Wide Identity by State” analysis, four groups were identified, one of which included pigs from Guadyerbas, USYU, and YBHP. Between populations, YBHP was closely related to the hairless pigs from Guadyerbas, USYU, and Canarias. Principal component analysis showed the same result. According to the results obtained from the runs of homozygosity investigation, aimed to get pools consensus of regions of overlapping, 119 SNPs associated with genes and biological processes were identified. The BMP7 and NSUN2 genes were associated with epithelial cell differentiation, morphogenesis, and epithelial development. For nutrient metabolism: energy, the HADHA, PPARA, ADD1/SREBF1, and FAT1genes were identified.","PeriodicalId":9119,"journal":{"name":"Brazilian Journal of Veterinary Research and Animal Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49289226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to verify whether the injection of B vitamins at the acupuncture point governing vessel 14 (GV14) can influence the parasitic load or host parasite interaction in naturally infected ewes during the peripartum period. Four weeks before parturition, 25 ewes were divided into five treatment groups: (1) Dose Control: 0.2 mL of B complex via IM; (2) Drug Control: 2 mL Complex B via IM; (3) Acupoint Control: 0.2 mL of Water at GV14 point; (4) Control; (5) Test group: 0.2 mL of B complex at the GV14 point. Treatments were performed at weeks -3, -1, 2, 4, and 6 about the parturition time. Fecal samples to estimate the parasitic load by fecal egg counts (FEC) and total blood samples for hemogram examination were performed seven days after the treatment, coinciding with weeks -2, 3, 5, and 7 about the parturition time. The number of peripheral eosinophils was higher in group 3 than in group 1 (p <0.05). Although groups 3 and 5 had lower mean values of FEC and higher hematological values at the time of weaning, these differences were not statistically significant (p> 0.05) according to the F test. However, all animals in groups 3 and 5 maintained low parasitism levels until the end of the experiment. Further studies should be performed with larger sample sizes and minor changes to the experimental protocol to elucidate the role of GV14 acupoint stimulation in the host-parasite relationship.","PeriodicalId":9119,"journal":{"name":"Brazilian Journal of Veterinary Research and Animal Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42556371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, we found phenotypical resistance to beta-lactam antibiotics in 50% (20/40) of the strains analyzed, forming two groups, one with resistant isolates and the other with non-resistant isolates. The cytotoxicity of the isolates did not vary among the groups. In addition to having this characteristic, some multiresistant isolates produced significant amounts of toxins.

In this study, 230 Nelore heifers, 20±2 months of age, were subjected to an estradiol progesterone-based timed artificial insemination (TAI) program. On Day 0 of the TAI protocol, the heifers were examined by transrectal ultrasound to record videos of the ovaries. Later, in the darkroom of the laboratory of images, the videos were analyzed for AFC (≥ 3 mm) of each ovary. Females who failed the first TAI were resynchronized with the same hormonal protocol. The pregnancy status was evaluated by ultrasonography 30 days after each FTAI. The general mean of the AFC was 22.0 follicles. Thus, the heifers were divided into 2 groups according to AFC: Low AFC (˂ 22 follicles, n = 114), and High AFC (≥ 22 follicles, n = 116). No differences (P > 0.05) in the pregnancy per AI (P/AI) were observed between the Low and High AFC groups, and between pubertal and prepubertal categories. The P/AI was not different between heifers that displayed or did not estrus (P = 0.2). However, considering the estrus response of each AFC group, High AFC heifers that displayed estrus had greater P/AI (P = 0.01) than High AFC heifers that did not display estrus. In summary, AFC and pubertalstatus did not affect the fertility of Nelore heifers. In contrast, the P/AI of heifers that did not display estrus was lower than heifers observed in estrus only in the High AFC group.
