{"title":"Is Pregnancy Length in Martina Franca Jennies Influenced by Lunar Cycle?","authors":"A. Carluccio, M. Veronesi, G. Ippedico, A. Contri","doi":"10.26502/AVSM.023","DOIUrl":"https://doi.org/10.26502/AVSM.023","url":null,"abstract":"In humans and animals there is a popular belief that spontaneous parturition, and therefore pregnancy length, could be influenced by the lunar cycle, but results from humans are often impaired by multiple variables of the studied population. In domestic animals those problems can be limited by studying restricted population, such as a single breed, reared under uniform conditions. The present study aimed to assess the possible influence of the lunar cycle on pregnancy length in Martina Franca jennies belonging to a single breeding farm. The retrospective study was performed on data collected from 96 Martina Franca healthy jennies with a normal singleton pregnancy course. The present study showed that, whit lunar cycle divided in 4 lunar phases, neither lunar phase at ovulation, nor lunar phase at foaling significantly influenced pregnancy length (371.8±6.45 days). Pregnancy length was not significantly influenced also by the month of the year in which ovulation and spontaneous foaling occurred, as well as by jennies’ age and foal’s sex. In conclusion, pregnancy length in Martina Franca jennies is very variable (335-395 days) but does not seem to be influenced by lunar phases at ovulation or at foaling, month of ovulation and foaling, and by jennies’ age and foal’s sex. Further studies are needed to clarify the reasons for this pregnancy length variability in Martina Franca donkey breed.","PeriodicalId":305084,"journal":{"name":"Archives of Veterinary Science and Medicine","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126990815","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}

Gautam","doi":"10.26502/avsm.007","DOIUrl":"https://doi.org/10.26502/avsm.007","url":null,"abstract":"Repeat breeders are the animals with more than 3 to 4 inseminations after calving having regular cyclicity yet failed to conceive. Therefore, it is considered as one of the most emerging and frustrated reproductive disorders among dairy herds in Nepal that hinders favorable productivity and causes heavy economic losses to the livelihood of the farmers. We performed a systemic review to be acquainted with hormonal therapy as a treatment of repeat breeding. The aim of the present review is to summarize the current information about the ongoing methods in the treatment of repeat breeders. Based on the review of articles, it was found that gonadotropin-releasing hormone (GnRH) administration improved the conception rate in repeat breeder buffaloes and cows bearing dominant follicle in the ovary. In repeat breeder buffaloes and heifers with predominant corpus luteum and adequate body condition score (BCS), administration of PGF2α increased the pregnancy rates. Conception rate with Ovsynch protocol (GnRH-PGF2α -GnRH-TAI) usually was improved when initiation of program done during mid-diestrus i.e. days 5-12 of estrus cycle. Exogenous progesterone administration resulted in increased serum progesterone level during PGF2α injection that usually improves fertility of lactating dairy cows. In conclusion, hormonal treatment is considered to be most effective treatment to mitigate the problems of repeat breeding syndrome in Nepal. However, the first step of treatment involves good care, nutrition, better oestrus detection, timely insemination, periodic deworming to control parasite load and management of mating with bulls.","PeriodicalId":305084,"journal":{"name":"Archives of Veterinary Science and Medicine","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122671516","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}

A recombinant chimeric protein RetroMAD1 is described for the first time in the treatment of FeLV. The chimera has an A-B-C configuration comprising of multiple documented antiviral domains that can potentially overcome single point mutation driven resistance by multidomain action. Oral administration of RetroMAD1 was given daily at 0.4mg/kg/day divided equally into two feeds roughly 12 hours apart for one month to highly symptomatic FeLV cats in Brazil. RetroMAD1 treated cats were monitored for survival until day 433 and untreated cats were monitored until day 173. A significant different in survival rate of 73% (treated N=55) versus 33% (untreated N=21) existed. Gingivitis, F.U.R.D. and anaemia were shown to improve significantly as signs indicating improvement in quality of life. Some of the RetroMAD1 treated cats were given interferon treatment by their respective vets as supportive treatment (N=14) that gave a slightly improved survival outcome compared to those given only RetroMAD1 and other supportive medication. Being orally administered, this protein may be easily administered by cat owners. In addition, biochemistry and CBC data also indicated that RetroMAD1 is safe and well tolerated. A safe, efficacious oral delivery antiviral chimera will be very useful for veterinary treatment especially if it is also broad-spectrum in nature.","PeriodicalId":305084,"journal":{"name":"Archives of Veterinary Science and Medicine","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134064821","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}

Samples of urine from aborting sows were collected to recover the pathogen, amplify its 16S rRNA gene to confirm its identity and monitor cell density in McFarland Units (MFU) as a measure of susceptibility to antibiotics. The study permitted the isolation and evaluation of Leptospira spp. morphology, demonstration of 3 amplicon products of the 16S rRNA genes with molecular sizes of 1050 to 1080 bp and identification of 2 Leptospira spp. and L. hyos after gene sequencing. The susceptibility of the identified L. hyos to Cephalexin, Neomycin, Clindamycin, Ciprofloxacin and Sulfamethoxazole prepared at different concentrations (25 μg, 35 μg and 50 μg) and evaluated after 6 and 12 hour-exposure time was marked by lower cell densities of recovered L. hyos relative to the application of higher (35 μg and 50 μg) antibiotic concentrations. Significant reduction in cell densities at 12-hr compared to data obtained on the 6-hour were demonstrated and underscored the susceptibility of L. hyos as effects of antibiotic concentration and duration of exposure time. The bactericidal action of 25 μg Ciprofloxacin; and 25 and 35 μg Sulfamethoxazole against L. hyos were established at 6-hour exposure time and that this bactericidal action was maintained until the 12-hr with the application of Neomycin and Ciprofloxacin at 35 and 50 μg and Sulfamethoxazole at 50 μg.
