For this purpose, records of 663 lactations from 248 buffaloes were evaluated. Total milk yield was 1344.91 liters, lactation length was 291.20 days, calving interval was 453.55 days and milk by day of calving was 2.77 liters. Parity did not significantly affect total milk yield, but had a significant effect on lactation length, calving interval and milk by day of calving interval. First calving buffaloes had a longer lactation, a longer calving interval and in consequence lower productivity than buffaloes with two and three or more calving. Second calving buffaloes had intermediate and significantly different values than buffaloes with three or more calving. Calving interval was positively correlated with total milk yield (r = 0.34983, p <0.0001) and length of lactation (r = 0.67408, p = <0.0001); and negatively with milk by day of calving (r = -0.41263, p<0.0001). In conclusion, parity affected the productive performance and calving interval, with buffaloes of one and two calving being less productive due to a longer calving interval. An increase of milk yield is related with a longer calving interval, therefore, buffaloes of one and two calving, must be provided with optimal management conditions, which allow them to support milk yield and not to compromise the reproductive performance.","PeriodicalId":36721,"journal":{"name":"Journal of Buffalo Science","volume":"7 1","pages":"13-16"},"PeriodicalIF":0.0,"publicationDate":"2018-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43757107","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}

Subclinical mastitis is characterised by a non-alteration of the milk but can cause food poisoning by production of enterotoxins in milk. Knowledge about the genetic variability within different S. aureus populations would help in the design of efficient treatments to prevent subclinical mastitis and provide useful data for epidemiological studies. The aim of this study was to characterize the genetic nature of the S . aureus cultured from subclinical bovine mastitis occurring in 16 farms in the middle western Anatolia. Methods : Two hundred sixty eight milk samples positive with California Mastitis Test (CMT) suggesting the subclinical mastitis of lactating cows in 16 different farms in the Middle Western Anatolia were collected and S. aureus were isolated. Identification was carried out by traditional tests and ribotyping confirmed the identification. Staphylococcal Enterotoxins (SE) were detected and typed by Staphylococcal Enterotoxin Test Reversed Passive Latex Agglutination (SET-RPLA) test kit. Genetic characterisation of the isolates was carried out by both ribotyping and pulsed field gel electrophoresis (PFGE). Results : A total of 77 isolates of S. aureus were purified and analysed by both biochemical identification and genotyping. Only 4 isolates (5.19 %) of S. aureus were recorded as enterotoxin positive. Genetic characterisation of the isolates was carried out by ribotyping revealed eight ribotypes while pulsed field gel electrophoresis (PFGE) was more discriminative representing 19 pulsotypes. Conclusion : This study shows no significant association between enterotoxin production, ribogroup and pulsotype profile of the S. aureus isolates collected from the Middle Western Anatolia.","PeriodicalId":36721,"journal":{"name":"Journal of Buffalo Science","volume":"7 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43863005","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}

It causes intense itching and restlessness, altering feeding habits, thus reducing animal productivity. This parasitosis is seldom studied, as it does not lead to significant animal mortality or financial losses. In this project, we evaluated the efficacy and safety of two commercially available products for control of pediculosis in naturally infested buffaloes. A total of 24 milk producing, clinically healthy female buffaloes that were naturally infested by lice were included in this study. Animals were equally distributed into two groups: group 1 was treated with a single dose of pour on Fipronil (1%, Carval de Colombia, 1 ml of product per 10 kg of live weight). Group 2 was treated with a single dose of deltamethrin (5%, Bioara, SA), at a final concentration of 0,1% applied with an aspersion pump as a single bath of 4 liters of diluted solution per animal. Lice were counted weekly from day 1 to day 58 post-treatment. Up to day 23 post-treatment, no significant differences in efficacy were observed between products.Fipronil 1% consistently exhibited an efficacy above 70% from day 8 and until 30 day of the study. These results suggest that both products are efficient and safe to control lice infestations in buffaloes. However, fipronil 1% exhibited a greater residual effect, which reduces the number of baths required to treat infested animals, and reduces the probability of selecting for drug-resistant lice populations.","PeriodicalId":36721,"journal":{"name":"Journal of Buffalo Science","volume":"7 1","pages":"8-12"},"PeriodicalIF":0.0,"publicationDate":"2018-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46838138","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 idea that the quantity of follicles and oocytes in ovaries impacts on fertility is a long-held tenet in reproductive biology (46), Follicle formation occurs during fetal life in ruminants and primates. The establishment of the pool of primordial follicles is critical to a female’s reproductive success, but very little is known about how this important developmental process is regulated. It has been reported is has been reported in buffaloes the effect of season in the gene expression of oocytes and follicles (47) .However, until now very few studies has been attempted to evaluate this fundamental hypothesis, it is possible to think that animals with low follicle count such buffaloes has lower fertility than cattle but this must be demonstrated. The aim of this review is to present evidence related to the differences in reproductive potential in two closely related bovines: buffaloes ( Bubalus bubalis ) and cattle ( Bos taurus and Bos indicus ), with special emphasis in the role of antimullerian hormone (AMH) and discuss their possible role in the application of reproductive biotechnologies.","PeriodicalId":36721,"journal":{"name":"Journal of Buffalo Science","volume":"6 1","pages":"74-80"},"PeriodicalIF":0.0,"publicationDate":"2017-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48501442","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}

From January 2014 to December 2016 a total number of 100 cows naturally affected by acute E-coli mastitis randomly were allocated into two groups.
