A sero-prevalence study of caprine brucellosis by using serological tests to determine the prevalence and the potential risk factors associated with brucellosis in the study area. Sera samples were collected from 384 unvaccinated and apparently healthy adult goats. The samples were examined serologically by Rose Bengal Plate Test (RBPT) for first screening test and Compliment fixation Test (CFT) for confirmations. All positive sera samples to RBPT were confirmed with CFT. Out of the total 384 samples were examined serologically 1.56% were reacted to be positive for RBPT screening tests and these positive samples continue to retest with CFT, it indicated as 0.78% prevalence of brucellosis from the examined samples. From the six-peasant association the highest sero-prevalence results recorded in CFT were Gemechu (1.75%) followed by Bissedemo (1.37%) and Shek Hussen (1.19%). Caprine brucellosis sero-prevalence statistically not significantly difference (P> 0.05) on sex (χ2 = 0.274; P= 0.600). The present study showed that caprine brucellosis is an endemic and widely distributed disease in goat, in the study area. In conclusion; In Ethiopia, domestic goats play an important role in the national economy. It has been estimated that there are approximately one hundred million domestic animals in Ethiopia, 23% of which are goats upon this caprine brucellosis have a negative influence on both food security and important export commodity. Therefore: effective extension system and programs that could raise public health awareness on disease transmission to human and how to care and handle their animals. Control programs should be designed and implemented with the participation of all stakeholders (farmers, government, privet sectors and veterinarians). Further studies should be conducted on the high-risk groups and the associated risk factors of caprine brucellosis in different agro-ecology parts of the country.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117270874","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}

Mastitis is a pathology featured to inflammation of the udder, caused by fungi, bacteria or viruses. Mastitis treatment is by antibiotics intra-mammary infusion, and the indiscriminate use can cause resistance from the bacteria, hindering the therapy of this disease. The aim of this work was evaluated antimicrobial activity of Chlorella vulgaris, Arthrospira platensis and Dunaliella tertiolecta extracts against isolates causing goat (19 strains) and bovine (16 strains) mastitis, using broth microdilution method. The extracts were obtained using Sodium Acetate Buffer, 1 M, pH 5.5 (SAB), Water (W) and Chloroform-methanol (CM). The three microalgal extracts showed interesting antimicrobial properties, the lowest MIC value was of 25 μg/mL for C. vulgaris (CM extract) and Dunaliella tertiolecta (water extract) against Staphylococcus sp. of bovine mastitis and 25 μg/mL using SAB and water extracts from A. platensis, which mostly inhibited the growth of isolated Staphylococcus sp. of goat mastitis. These results could mean a breakthrough in the veterinary pharmaceutical industry and consequently a direct and effective applicability in veterinary medicine, reducing damage caused by mastitis in bovine and goat herds.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117022590","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}

The high cost of superovulation has been cited as a major contributory factor. The research was carried out to test the effect of four different dose rates of follicle stimulating hormone (FSH) used for superovulation. Ultrasound and manual palpation were used to determine the number of follicles and corpora lutea formed. Harvesting and grading of embryos was carried out to determine the quantity and quality of embryos produced. An average of three embryos per donor was recovered, though there was a potential of more than six embryos. One third of the donors failed to ovulate, another third produced 1 to 3 embryos while a third produced over three embryos. All donor cows had several ovulatory follicles ranging from 7.7 to 13.7, but the failure for some to ovulate needs further investigation. There was no difference in embryo quantity and quality between the different FSH dose rates. The season, technique and animal factors were shown to influence embryo production. It’s recommended that super ovulation may be carried out in Kenya using 200 mgs of FSH. This will reduce the cost of embryo production by at least 25% or more depending on the number of embryos harvested per donor.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125096369","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}

Farmer’s knowledge about the disease and its management in the absence of a commercial vaccine as well as their knowledge on the existing potential vector (for FMD) such as the stable fly in the absence of mass fly control campaigns in Vina Division is necessary for the mitigation of FMD spread. A questionnaire survey was carried out in an FMD outbreak season in Vina, in August 2018 with target population including cattle owners/herders, drug sellers and veterinary chief of centers from Dang, Djalingo and Galdi cattle markets. According to cattle owners/herders, FMD outbreaks occurred at the end of the rainy season which corresponded to peak occurrence periods of stable flies in their herds. This observation creates a novel avenue on the potential transmission of FMD by the most frequent stomoxyidae and other flies in Vina Division. Antibiotics (especially Moore-Oxy®) were highly solicited for FMD management while a combination of agricultural insecticides (DD force® +CYPERCOT®, PRIME FORCE® +CYPERCOT® and SNIPER®+CYPERCOT®) and some veterinary insecticides (COW WASH®, CYPERMETHRINE®, KXTIK®, DELTAMETHRIN® and DIDETEKI® POURON) were used for fly control.

This review approached the milk fatty acids composition, physiological mechanisms and dietary modifications that may lead to changes in the fatty acids profile and their influence on human health. The proportions of saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) on milk have variations that are associated with many factors and their interactions. In the rumen, the microorganisms promote changes in the diet fatty acid profile through biohydrogenation, factor that may difficult the study of different nutritional management in the final product composition, and because that, studies should match the lipid profile with the ruminal microbiota arrangement. In the mammary gland, fat formation is a complex process which milk fatty acids are derived from “de novo” synthesis in epithelial cells and from long chain fatty acids arising from diet and adipose tissue mobilization, the last one in negative energy balance. For beneficial effects on human health, a lower n-6: n-3 ratio may reduce the risk of coronary artery disease. Future studies may continue including modifications in the fatty acid profile using different diets, but at a molecular level and with effects on gene expression of enzymes involved in the milk fat formation process. In addition, animals’ genetic manipulation and selection to obtain products with desired specific composition may be more deepen in the next studies.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133271342","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}
