This disease produces changes in the animal ́s immune system that may affect vaccine efficacy. During the last 10 years many reports have highlighted the association of BLV infection with a diminished or modified immune response against routinely used cattle vaccines. Our group has focused on studying the possible role of BLV infection on the immune response elicited by foot-and-mouth disease primo or multiple vaccinations making use of serological assays aimed to characterize the antibody response in terms of IgG-subtypes and avidity. These tools demonstrated to be very useful for analyzing the effects of BLV in FMD vaccine immunity. The use of simple high-throughput assays delving on the quality of the antibody response is paramount for assessing vaccine efficacy and can help in analyzing the impact of BLV infection at herd level.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130241731","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}

Guinea pigs of both sexes weighing (5-10kg) were divided into six groups (A, B, C, D, E and F) with five guinea pigs in each group. At day zero, to establish the baseline data, all the animals in each of the six groups were bled for haematology and serum biochemistry and clinical parameters (rectal temperature, respiratory rate, pulse rate and heart beats) were recorded while general body condition and physical signs were also evaluated. Groups A, B and C were intraperitoneally (IP) inoculated with 1×106 dose of Trypanosoma brucei brucei contained in 0.5 ml of blood. Thereafter, blood samples were collected every other four (4) days for evaluation of haematology and serum electrolytes through the experimental period. Group D, E and F was uninfected control. All the infected groups (A, B, and C) had a pre-patent period of 16 days with similar levels of parasitaemia of 45.7±3.38 across the groups. The observed clinical signs among the infected groups (A, B and C) were pyrexia, pale feet, snout, pinnae and mucous membrane, anaemia, dullness, emaciation and loss of weight. In group A, a mean parasitaemia of 2.8 ± 0.84 occurred by day 16 postinfection post infection which continued to rise significantly without abating (p<0.05) to a peak count of 120.2 ± 5.48 by day 40 post infection. Similar findings were noticed across the groups. In groups D, E and F, their respective pre-infection RBC values of 6.20 ± 1.24, 6.24 ± 1.24 and 6.18 ± 1.24 remained constant (p>0.05).

The present cross-sectional study was conducted to assess hygienic practices, determination of bacterial quality of milk and isolation and identification of bacterial pathogens in milk at each critical control point throughout the value chain in MU-CVM and Kalamino dairy farms in Mekelle from August to November 2017. A total of 40 respondents were interviewed and subsequently, 84 milk samples were collected for laboratory analysis including bacterial load assessment and isolation and identification of bacteria. Total bacterial plate counts from milk were conducted. Isolation and identification of the bacteria in the milk was also conducted following standard methods. Results showed that, attendants of study dairy farms, managing their cattle in moderate hygienic environments and practicing intensive farming system. The mean total bacterial plate counts of raw milk samples analyzed were 2.15x108 cfu/ml (udder), 3.4x108 cfu/ml (storage area in the farm) and 5.96x108cfu/ml (distribution center milk container). The increment of both counts at each critical control points was observed statistically significant (P=0.000). However, there was no significant variation between the two farms (P= 0.074) in the mean total bacterial count. About 26.7%, 50%and 62.5% from teat, storage area in the farm and distribution center milk containers, respectively at MU-CVM and 40.9% from the teat, 62.5% from milk storage area and 75% from distribution center milk containers, respectively at Kalamino dairy farm were graded of poor quality. In the course of this study, the frequent bacterial pathogens isolated from raw milk samples taken from different critical points include: E. coli, S. aureus and Streptococcus spp. From the result there were hygienic practices in the study farms, but the quality of milk used for human consumption area was found inferior quality according the standard level. Thus, it is important practice proper and restricts hygienic practices, proper transportation and storage and reducing the milk storage time, raising the awareness of dairy workers to enhance the quality of milk used for human consumption.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130577998","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}

These efforts are supported by the fact that camel breeding is characterized with negligible fodders and stable building costs, in comparison to other ruminants’ species. Nevertheless, according to our findings on the field, it turns out that the conduct of camelids’ dairy farms, is often characterized by a search for immediate benefits by herders or livestock managers, to the detriment of animals’ welfare in production as well as their sanitary status [2]. For example, among the most spread camelids’ diseases, subclinical mastitis causes suffering of she-camels, if it is not detected precociously [3]. Also, clostridial diseases as tetanus and enterotoxaemia, mangue caused by Sarcoptes sp., cause pain and death of camels [4]. In addition, the negative influence of stress and unfavorable rearing conditions has been regulated by the recommandations of the Farm Animal Welfare Council [4]. In this mini-review we expose our point of view on the possibility of application of health welfare standards in camel breeding in the situation of Algeria, according to facts and field constraints. Some dominant diseases are done as example.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117044239","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}

Though the number of female cattle in Ethiopia is high (55.38% (32.0 million)), the production and reproductive performance (crucial factor) needs to be improved. For modern dairy industry, reproductive performance is the most important to determine the efficiency of dairy cattle. Even though, age at first service, age at first calving, day’s open, calving interval and number of services per conception are the most factors; management and cowlevel factors also determine the reproductive performance of dairy cow. The indigenous cattle of age at first service, age at first calving and calving interval is 34.4±2.28 to 56.16±7.56 months, 33.9 to 57.69±1.11months and 13.59±0.26 to 26.04 months, respectively. There is wastage of reproductive due to environmental, genetic, disease and management factors. So, to improve the productivity and production of native breeds, detail understanding of current performance, identifying challenges and opportunities with the causal factors is very important.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130143153","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}
