To identify signatures of selection, we used four approaches, runs of homozygosity (ROH), Wright’s fixation index (F<sub>ST</sub>), cross population extended haplotype homozygosity (XP-EEH), and ratio of extended haplotype homozygosity between populations (Rsb). According to F<sub>ST</sub> results, SAR and IST were the most divergent breeds. The latter breed showed the largest ROH-based inbreeding. A large selection signature on chromosome 6 (33.26–46,31 Mb) was found by all involved approaches as associated with IST.

The prevalence of this group of pathogens may be up to 50 % in some dairies. Dry-off is a common production point to address these infections through the extra-label use of long-acting intramammary antimicrobial products which are approved for dairy cattle in the US. However, the impacts of this treatment on antimicrobial resistance development are unknown in goats. The objective of this project was to evaluate the impact of intramammary antimicrobial use at dry-off on antimicrobial susceptibility testing and antimicrobial resistance gene profiles of NAS isolates from commercial farms in the United States which were associated with persistent or new subclinical intramammary infection during the dry period in goats. The current study is a continuation of a previous study which evaluated the efficacy of intramammary antimicrobial treatment for curing subclinical mastitis caused by non-aureus staphylococci. That analysis included 260 does who provided the isolates for the current study. Antimicrobial sensitivity testing was performed using a commercially available broth microdilution plate designed for treatment of mastitis in dairy cattle on dry-off and post-kidding samples for isolates that failed to cure or developed new NAS infections after treatment with one of two β-lactam (cephaparin, CEPH; cloxacillin, CLOX) dry cow therapies or in non-treated control animals to evaluate the impact of targeted dry therapy on phenotypic and genotypic antimicrobial resistance development of NAS in dairy goats. The most prevalent NAS associated with non-cured infections for all three treatment groups was &lt;em&gt;Staphylococcus epidermidis,&lt;/em&gt; while the most common NAS associated with new infections after kidding was &lt;em&gt;S. equorum&lt;/em&gt;. There were small variations in MIC for multiple drugs when data was evaluated by treatment group and location, though these changes did not form a consistent pattern and are likely due to the small sample size and farm-level differences in pathogens. The minimum concentration of penicillin (surrogate test for β-lactamase producing strains) required to inhibit growth in 50 % of isolates (MIC50) and 90 % of isolates (MIC90) did not change for non-cured isolates after antimicrobial therapy across the entire study population.

Significant reduction in their scrotal and testicular measurements was observed, as well as changes in their sexual behavioural patterns. BB ram testosterone level also significantly reduced at Day 14 of heat treatment. Cortisol level peaked at Day 7 and declined significantly by Day 14, likely indicating that physiological adaptation towards heat stress had begun to be employed by BB rams by the end of the treatment.

Flooring is an important aspect of the housing of goats, as it directly affects their health and welfare. Goats in intensive housing systems are commonly held on organic materials, like straw or sawdust, or on slatted concrete or wooden floors or metal mesh. As all of these floor types are different from what goats encounter in nature, these floor types might not be optimal for the welfare of these goats. This article critically examines the impact of various types of flooring on the welfare of goats in intensive housing systems. We found that conventional flooring, such as straw, sawdust and slatted or mashed floors, are least preferred by goats, as compared to solid, inorganic flooring, with rubber seemingly the most preferred. These findings contrast current practices in commercial settings, where organic materials are often used, for practical reasons, which not only affects welfare, but also negatively impact the health of the goats by affecting air quality and facilitating bacterial growth. Slatted floors, though promoting a better air quality and reducing bacterial growth, were least preferred by the goats and were associated with claw health problems. Therefore, rubber mats seem, based on the available literature, to be the preferred floor type when looking at welfare of goats in small scale settings. However, further research is needed to further innovate and develop flooring that promotes welfare and is applicable in large-scale commercial settings. As the current literature often suffers from bias, future studies aiming to determine the effect of flooring on the goats’ welfare should improve repeatability of research and control external factors to prevent bias, such as indoor climate and familiarity of goats with certain types of flooring, and also determine long-term effects of flooring on goat welfare with longitudinal studies in commercial, large-scale settings.</div></div>","PeriodicalId":21758,"journal":{"name":"Small Ruminant Research","volume":"252 ","pages":"Article 107616"},"PeriodicalIF":1.4,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145044294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
