Coxiella burnetii is also zoonotic, presenting a concern for public health. Despite their economic importance in the livestock sector in Sub-Saharan Africa, little attention has been given to these pathogens of sheep and goats. This cross-sectional study aimed at establishing the infection rates of Coxiella burnetii and Ehrlichia ruminantium in clinically healthy sheep and goats from Chalinze and Muheza districts in Tanzania. The PCR results revealed that of 223 animals sampled, (31.8%, n = 71) were positive for at least one pathogen. The most frequently observed pathogen was C. burnetii (16.1%, n = 36), followed by E. ruminantium (12.6%, n = 28) and their co-infections (3.1%, n = 7). The prevalence of these TBPs differed significantly (p = 0.020) among sheep (27.9%, n = 17) and goats (34.1%, n = 57). The prevalence of C. burnetii was (11.5%, n = 7) in sheep and (17.9%, n = 29) in goats. On the other hand, the prevalence of E. ruminantium was (9.8%, n = 6) for sheep and (13.2%, n = 22) for goats. The co-infection of C. burnetii and E. ruminantium differed significantly (p < 0.001) among small ruminants. Only the prevalence of C. burnetii increased significantly (p = 0.038) with increasing age. The observation of DNAs of TBPs in apparently healthy sheep/goats suggests that these animals have either established a state of enzootic stability against the pathogen or infection was by non-pathogenic variants of the pathogen. Such animals continuously act as sources of infection for ticks and other hosts, including humans, hence facilitating the transmission and maintenance of the pathogen in an area. It is thus essential to continue monitoring these pathogens regardless of the clinical status of the small ruminants.","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 4","pages":"193"},"PeriodicalIF":1.7,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144035931","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}

This study evaluated the effects of Moringa oleifera leaf meal (MOLM) supplementation on intake, growth performance, oxidative stress, behavioral responses, and economic outcomes in early weaned Landlly piglets. A total of 16 Landlly piglets, weaned at 35 days with an average body weight of 8.66 ± 0.38 kg, were used in this study. These piglets were randomly divided into two groups, with 8 piglets in each group. The control group was fed a basal diet, while the treatment group received the same basal diet supplemented with 5% MOLM. MOLM supplementation significantly improved growth performance, with the treatment group achieving a 9.24% higher final body weight and a 17.73% greater body weight gain compared to the control group (P < 0.05). Oxidative stress, measured through malondialdehyde levels, was significantly reduced in the treatment group (P = 0.04), indicating that MOLM mitigated lipid peroxidation and oxidative damage. Behavioral observations revealed a significant reduction in stress-related like belly nosing (P < 0.001). Additionally, cortisol levels were significantly lower in the treatment group by day 14 (P = 0.013). MOLM supplementation resulted in a lower cost of rearing per piglet and a higher net profit. This study concluded that MOLM supplementation not only improved growth performance, reduced oxidative stress and stress-related behaviors but also provided a substantial economic benefit, making it a viable nutritional strategy for improving the profitability in piglet production systems.","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 4","pages":"194"},"PeriodicalIF":1.7,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144055515","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}

Tsetse entomological surveys, AAT prevalence data together with environmental (climate, vegetation and topographical) explanatory data were used to map the presence and prevalence risk. Tsetse fly surveys were done and the vector was found mostly in areas north of Lake Kyoga and islands in Lake Victoria. Animal trypanosomiasis prevalence data was obtained from published works and samples collected and analysed during COCTU field operations. AAT was mostly prevalent in northern region. Through linear regressions, it was found that AAT prevalence was mainly significantly (P ≤ 0.001) contributed by temperature variance, precipitation of driest month, precipitation of the warmest quarter, precipitation of coldest quarter and recent annual mean precipitation climatic and vegetation cover. Tsetse flies trapped per day (FTD) were significantly (P ≤ 0.05) associated to precipitation of the wettest quarter, precipitation of coldest quarter and annual mean land surface temperature difference climatic factors. Topographical factor (altitude or elevation) did not influence the model outcome for both while vegetation didn't influence the vector model outcome. AAT and tsetse flies were widely prevalent in the northern and northeastern regions of the country (areas north and northeast of L. Kyoga). The risk reduced in areas south of the lake with the exception of areas around big water bodies and some conservation areas. These findings indicate that initiative-taking measures in vector and disease control should be directed towards the northern hemisphere of the country.","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 4","pages":"191"},"PeriodicalIF":1.7,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144048283","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}

It encodes a protein that has emerged as a promising molecular target for the management of metastatic disease and has shown potential for clinical utility. However, studies investigating the association between this gene and growth traits in sheep are lacking. This study aimed to assess the possible biomarker capacity of KISS1 by evaluating its association with growth traits in two economically important sheep in the Middle East, the Iranian Karakul and the Iraqi Awassi. Genotyping was conducted using PCR-single-stranded conformation polymorphism (SSCP), and the variation of the KISS1 gene was linked with several growth traits at three-month intervals starting from birth until one year of age. In a total of 180 Karakul sheep and 200 Awassi sheep, only one SNP (72G > C) was detected, which had not been previously reported in sheep. The identified novel SNP showed significant associations with the majority of growth traits measured at the ages of three, six, nine, and twelve months. At the age of three months onward, lambs with GG genotypes showed higher growth trait values compared with those with the GC and CC genotypes, respectively. Due to these remarkable associations, the 72G > C SNP is suggested as a promising marker for growth traits in both breeds. This is the first study that demonstrated the importance of KISS1 as a possible tool for evaluating growth traits in Awassi and Karakul breeds with the possibility of being applied to other breeds via large-scale investigations.","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 4","pages":"187"},"PeriodicalIF":1.7,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144041463","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}

The incidence of SB was 6.64%. Among the evaluated risk factors, BCS was a significant risk factor for SB. There was a 73.7% lower odds (lower odds odd ratio, OR = 0.246) of SB for dams with a gestation length ≥ 305 days, compared to those with a gestation length < 305 days. The risk of SB decreased steadily with increasing dam parity. The odds of SB were 2.48 times higher in male calves compared to female calves. In comparison to the spring season, the probability of SB doubled during the summer season. Calf blood serum analysis showed that SB-born calves had higher blood biochemical and cytokines alterations than normal-born calves. On the other hand, immunoglobulins and glutathione peroxidase were significantly lower in SB-born calves. Our results indicated that factors related to the induction of inflammation and/or disrupted immune system responses, such as obesity, high temperature, and oxidative stress, are the main evoking factors for SB in buffaloes; therefore, protective measures against SB in Egyptian buffaloes should be based on controlling these factors, either by nutritional interventions or management practices.","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 4","pages":"183"},"PeriodicalIF":1.7,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12021697/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144011818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
