Unsaturated fatty acids decreased the intracellular lipid accumulation while maintaining glucose utilisation levels. However, unlike OA, self-administration of DHA only intensified lipolysis by 25% vs induced untreated control (IC), which may have a direct detrimental impact on the whole body’s metabolic state. DHA applied in equal proportion with PA elevated triglyceride accumulation by 10% compared to IC, but applied with OA, enhanced glucose uptake without any significant changes in the lipogenic drive and the lipolytic rate, suggesting that this unsaturated fatty acids combination may offer a considerable advantage in amelioration of obesity-related disorders.","PeriodicalId":9279,"journal":{"name":"BULGARIAN JOURNAL OF VETERINARY MEDICINE","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89543854","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 birds were reared from day one to 42 days of age on deep litter system and divided into four groups. Normal feed free of aflatoxin (AFB1), was given to the control (Group 1). The feed of Group 2 was supplemented with 0.5 g/kg Mycotox NG, aflatoxin (0.5 mg/kg feed) was supplemented to the feed of Group 3 and Mycotox NG (0.05%) + 0.5 mg/kg AFB1 - to the feed of Group 4. Production parameters (body weight gain, feed intake, feed conversion) and relative organ weights were recorded. The results showed that the total feed intake, final live weight of Mycotox NG + AFB1 treated birds (Group 4) at 6 weeks of age were significantly increased (P<0.01) as compared to birds treated only with AFB1 (Group 3). The total feed conversion ratio of the group given AFB1 only (Group 3) at 6 weeks of age was significantly increased (P<0.01) compared to controls while in Mycotox Ng + AFB1 treated birds (Group-4) it was significantly increased (P<0.01) by post treatment week 1 vs controls, but not as compared to birds treated with AFB1 alone. There was a significant increase in relative weights of liver, kidneys, spleen, heart, pancreas, proventriculus and gizzard in birds fed only aflatoxin (Group 3). The co-administration of Mycotox NG (0.5 g/kg feed) with AFB1 (Group 4) reduced the relative weights of thymus and bursa of Fabricius. The study concluded that dietary supplementation of Mycotox NG could partially neutralise aflatoxicity in geese.","PeriodicalId":9279,"journal":{"name":"BULGARIAN JOURNAL OF VETERINARY MEDICINE","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81083556","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}

Previously, protozoan abortions in small ruminants were attributed to T. gondii, but the role of N. caninum in these abortions was uncertain. The aim of this study was to investigate the role of T. gondii and N. caninum in ovine abortion in Urmia, northwest of Iran using a molecular method. Overall, 130 placenta and brain samples of aborted ovine foetuses were collected. Extracted DNA from placenta and CNS tissues of the aborted foetuses were analysed using PCR with primers specific for T. gondii and N. caninum. The association of the frequency of T. gondii and N. caninum infection of aborted foetuses with age and breed in flocks was also studied. The results showed that out of the 130 examined ovine foetuses, 5.3 and 2.3 % were PCR-positive for T. gondii and N. caninum DNA, respectively. In this study, no significant differences were recorded relating to Toxoplasma and Neospora infection in different age groups in flocks and among sheep breeds included in the present study (P>0.05). The results of this study proved the importance of T. gondii and N. caninum as reasons of abortion in the studied area.","PeriodicalId":9279,"journal":{"name":"BULGARIAN JOURNAL OF VETERINARY MEDICINE","volume":"102 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80621635","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 animals were distributed in 2 groups: group I (n=1055) – control animals that did not demonstrate the tongue play orosthenic syndrome and group II (n=48) – cattle manifesting this stereotypy. Both groups were uniform with regard to age, breed, body condition and sex. They were placed under equal housing conditions (animal hygiene parameters, feed quantity and quality) and activity regimens (walks, feeding etc.). It was found out that the causes for demonstration of the tongue rolling hyperactivity in cattle were the deprivation from food and boredom, due to deficiency of environmental stimuli. The studied stereotypy was observed in cattle in different age groups – suckling and weaned calves, as well as heifers, including pregnant ones. The tongue play activity was no longer exhibited by heifers after calving and moving into the basic herd of lactating cows. The highest intensity (up to 80%) of this orosthenic syndrome was manifested before the morning feeding, between 9.00 and 12.00 AM. Most commonly, the tongue rolling activity was found out in heifers between 13 to 25 months of age. The studied oral stereotypy was not accompanied with changes in measured clinical parameters – rectal body temperature, pulse and respiratory rates, rumen movements, as well as in other activities e.g. rumination, eructation, appetite, sentience, locomotion etc.","PeriodicalId":9279,"journal":{"name":"BULGARIAN JOURNAL OF VETERINARY MEDICINE","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83566405","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}

Rabbits were equally distributed into 4 groups: 1st - newborns, 2nd - 1 month old, 3rd - 2 months old and 4th - 3 months old. The cranial subcutaneous fat pad in newborns covered dorsal and ventral cervical and interscapular regions. As age advanced, cervical lobes underwent a rapid reduction but the development of interscapular lobes continued. IsFD in rabbits from 1st and 2nd group was composed of both white and brown adipocytes, while in 3rd and 4th groups it consisted of white adipocytes only. InFD in rabbits from all tested groups occupied respective inguinal region and no age-dependent changes in shape and topography were observed. In all groups InFD was composed of white adipocytes only. The highest growth rate of interscapular and inguinal adipocytes was established in one-month-old rabbits. Differences in anatomy and histology of interscapular and inguinal fat depots in rabbits could be successfully used for comparison in other experiments in the field of adipobiology and autologous transplantation, where fat depots undergo significant morphological changes.","PeriodicalId":9279,"journal":{"name":"BULGARIAN JOURNAL OF VETERINARY MEDICINE","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80862534","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}
