The samples to be studied were collected in several places of Comuna Comandante Nzaji in the municipality of Huambo, in the rainy period. They were dried, milled and transferred to the National Center for Agricultural Health (Cuba) for phytochemical screening. The main groups found were primary and secondary aminos, free phenols, tannins, triterpenes and / or steroids and alkaloids. The primary and secondary amino compounds, free phenols, tannins and alkaloids were found in high amounts in the leaves of I. hendecaphlla and for C. mubango were found in this same amount in addition to amines the triterpenes and / or steroids since phenols and alkaloids They were presented in moderate quantity and tannins in a mild way.

While, the combination properties are remain unknown. Therefore, in the current study we aimed to investigate the hepatoprotective effects of oral co-administration of RES and QE against acetaminophen (AA) induced hepatotoxicity in rats. Acute hepatotoxicity was induced by a single dose of 640 mg/kg AA. Then RES and QE were administrated orally for one week. The male Wistar rats were randomly divided into 6 groups including; normal, hepatotoxic group (AA received rats), N-acetylcysteine (NAC) group: AA + 150mg/kg/day NAC, QE group: AA + 20mg/kg/day QE, RES group: AA + 30 mg/kg/day RES and combination group: AA + RES (30mg/kg/day) + QE (20mg/kg/day). At the end of experiment, serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) were measured. Also, serum level of triglyceride, total cholesterol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein were measured (VLDL-C). Then the liver structure was assessed by histopathological examination. Serum and liver total antioxidant capacity (TAC) and malondialdehyde (MDA) were measured by photometry and fluorescence spectroscopy method, respectively in serum and tissue homogenate. The combination treatment significantly alleviated activity of specific liver enzymes and modulated lipid profiles parameters more than RES and QE treatment alone. Histopathological analysis indicated combination treatment remarkably led to improve liver injury more than RES and QE treatment separately. Also, co-administration of RES and QE normalized TAC and MDA levels in serum and tissue more significantly than single treatment. Oral co-administration of RES and QE normalized AA-induced hepatotoxicity by reducing lipid levels, MDA, liver enzymes and histopathological changes.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129779931","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 ten districts of Kaffa Zone, three districts were purposively selected based on their potential for indigenous chicken population and accessibility. From each rural kebeles those households who possess a minimum of five mature indigenous chicken were purposively selected. Then, data on both qualitative and quantitative variables were collected from 300 purposively selected households using a semi-structured questioner. The results indicated that majority of the respondent were female (71.1%) and 56% of them were illiterate. The average family size per household was 5.86. Farmers mainly keep their chickens in the kitchen (60.7%) and main houses (30.7 %). Maize (55.7 %) and sorghum (20.3 %) were the major feed supplements provided by the households. The average chicken flock size, age at first egg (months), average egg/hen/clutch (clutch size), clutch number and annual egg/hen/year were 8.68, 6.09, 12.3, 3.6 and 44, respectively. The average hatchability was 80.5%. The major production constraints were predators (72.7 %) and diseases (27.3 %) across the studied districts. The type of predators which are commonly occurring included Buteo jamaicensis locally known as “Gace”, Helogale hirtula locally known as “Shiifoo” or “Wociwoco”, Felis silvestris locally known as “Haallaro” and Felis catus locally known as “Kubbi Kullaro” accounted about 54.6, 24.4, 15.5, and 5.5 % respectively. The effective population size and rate of inbreeding were 486 and 0.111% indicating chicken populations in the study area are not exposed to inbreeding. In conclusion, the current study indicates illiterate female farmers were mainly involved in care and managing of chickens under scavenging system. The performances of chickens were comparable with the national reports under scavenging system; however, these performances were influenced by predators and diseases. Therefore, educating and training women’s should be implemented to improve the overall socio-economic status of the family and benefit them. In addition, successful intervention strategy should be carried out to effectively utilize the existing potentials of indigenous chicken populations in line with predator and disease control programs. Again, conservation of the indigenous chicken populations should also be considered before they have been diluted with exotic breeds","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121961452","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 association with risk factors such as- age, sex, treatment history, and body condition were also determined in the current study. Coprological methods including floatation technique and McMaster egg counting techniques were used for screening and counting the eggs of observed gastrointestinal (GIT) nematodes. Out of 384 fecal samples examined in the laboratory, an overall prevalence of 74.7% nematode infestation was recorded and it indicates 287 sheep harbors at least one genera of nematode out of 384 animals. The study revealed significant association (P < 0.05) within sex and the higher prevalence of nematodes in female animals was recorded compered to males and the higher prevalence of nematodes in untreated sheep than treated ones was recorded with significant association (P < 0.05) between the groups. The prevalence of nematodes had no significant association with other risk factors (body condition and age). The proportion of the study animals infected mildly, moderately and severely were (76.7%), (16.0%) and (7.3%) respectively. The majority of examined animal on average had the egg per gram of feces (EPG) less than 800. In conclusion, the study revealed that GIT nematodes were major parasitic infections of black head sheep in the study area. Therefore, effective strategic treatment and public awareness creation should be instituted in the study area.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"244 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124317130","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}
