The camelid male breeding soundness examination (BSE) is strongly recommended because natural mating remains the primary breeding method due to the challenges in semen cryopreservation and artificial insemination. Guidelines for the BSE have been proposed but not adopted in practice. The investigation of male reproductive failure includes history, general health examination, examination of the genitalia, semen evaluation, and testing for contagious diseases. Difficulties in ejaculate collection and semen viscosity are challenges in camelid male fertility investigation. This review summarizes the outcomes of BSE in our practice on South American camelids (SACs) and camels. The results and discussion are presented under four main categories: congenital defects, <i>impotentia coeundi, impotentia generandi</i>, and male reproductive emergencies. There is a difference between camels and SACs in the incidence of various disorders. Congenital defects are common in SACs in particular cryptorchidism, testicular hypoplasia and rete testis cysts. Orchitis is more common in camels, particularly in areas where brucellosis is prevalent. Testicular degeneration occurs in all camelids and has been associated with heat stress, aging, systemic diseases and overuse of anabolic steroids. Precise diagnosis of fertility impairment may require disease testing, testicular biopsy, cytogenetics and endocrine evaluation. A significant proportion of males are referred because of reproductive emergencies, due to poor management, which results in loss of genetic potential. Implementation of regular BSE is possible in SACs but can be difficult in dromedaries because of the large variation in breed characteristics and management systems.</p>","PeriodicalId":7955,"journal":{"name":"Animals","volume":"15 19","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12523255/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145297965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective control may lie in dynamic Integrated Pest Management (IPM), which relies on routine monitoring and adaptation to farm conditions. This study investigated how PRM infestations affect the night-time activity of hens. Three groups of eight hens, housed in enriched cages, were monitored with night-vision cameras over a two-month period, both before and after artificial PRM introduction, while PRM levels were simultaneously recorded. To quantify changes in behaviour, we developed an activity-monitoring algorithm that extracts both group-level and individual night-time activity patterns from video recordings. Group activity between 18:00 and 03:00 was analyzed hourly, and individual activity between 21:00 and 00:00 was classified into four activity categories. Before infestation, group activity declined after 19:00, remained low from 20:00 to 01:00, and peaked just before the end of the dark period. After infestation, activity remained elevated with no anticipatory activity peak towards the end of the dark period. Individual data showed an increase in time spent in the most active activity category from 24% to 67% after infestation. The rise in calculated activity was supported by a nearly 23-fold increase in annotated PRM-related behaviours, specifically head shaking and head scratching. These findings suggest that PRM mostly disrupted sleep from two hours after lights-off to two hours before lights-on and may have acted as a chronic stressor.

Plateau ruminants have long been subjected to extreme environments characterized by hypoxia, cold, and nutritional scarcity, which makes their dependence on energy metabolism particularly pronounced. However, existing research on the regulatory effects of dietary energy levels on the colonic function of plateau ruminants is still quite limited. This study involved 60 healthy male Pamir yaks with consistent body conditions, which were randomly divided into three groups: a low-energy diet group (YG, Neg 1.53 MJ/kg), a medium-energy diet group (QG, Neg 2.12 MJ/kg), and a high-energy diet group (RG, Neg 2.69 MJ/kg). Each yak was provided with 5 kg of mixed feed daily over a 170-day feeding trial. The results indicated that a high-energy diet enhanced growth performance in yaks (<i>p</i> < 0.05). However, it also induced local colonic inflammation, decreased levels of immune factors (IgA, IgG, and IL-10), and increased the abundance of potentially pathogenic bacteria, such as <i>Klebsiella</i> and <i>Campylobacter</i> (<i>p</i> < 0.05). Conversely, a medium-energy diet fostered the proliferation of beneficial bacteria such as <i>Bradymonadales</i>, <i>Parabacteroides</i>, and <i>Mogibacterium</i> (<i>p</i> < 0.05), and preserved immune homeostasis. Additionally, multi-omics analysis revealed that the QG group was significantly enriched in key metabolic pathways, including pyruvate metabolism and glycine, serine, and threonine metabolism and panto-thenate and CoA biosynthesis pathways, among others (<i>p</i> < 0.05), demonstrating a synergistic regulatory effect among the microbiome, metabolism, and host. In summary, a moderate-energy diet can promote the proliferation of beneficial bacteria in the extreme environment of the plateau. By regulating pathways such as Amino acid, Nucleotide, and Lipid metabolism, it coordinates the expression of key host genes and metabolite levels, effectively balancing immune signals and energy metabolism. This interaction establishes a beneficial microbial-metabolism-host pattern that supports colon health.</p>","PeriodicalId":7955,"journal":{"name":"Animals","volume":"15 19","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12524189/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145298170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assumed two broiler chicken populations with contrasting linkage disequilibrium (LD) levels, 38,500 SNPs, and 1000 genes controlling feed conversion ratio. We applied recurrent genomic selection over seven cycles. The genomic selection efficacy, expressed as realized total genetic gain, was proportional to the LD level and genotypic variance. Genomic selection required model updating to achieve a higher efficacy. The training set size required by genomic selection can be as low as 10%/generation. Under this low-cost scenario, the genomic selection efficacy was slightly lower than the maximum efficacy. There is no difference between genetic evaluation methods regarding the decrease in the genotypic variance due to selection. In general, additive value prediction accuracies and realized genetic gains were highly correlated. The accumulated inbreeding level was not high due to avoidance of sib cross.
