Epizootiološka istraživanja paramfistomoze u goveda

Epidemiological studies were undertaken at slaughter houses, live stock farms, veterinary hospitals and on household buffaloes under different management and climatic conditions in four different districts of the Punjab province. Infection rate was 7.83%, 12.33%, 7.17% and 4.25% respectively in the cattle at the slaughter house, live stock farm, veterinary hospital and at household cattle. Overall the highest prevalence in terms of season, 26% and 14.50%, was recorded during autumn at live stock farms and slaughtered cattle followed by 9.75% veterinary hospitals during summer and the lowest (2.5%) in household cattle was recorded during winter. It was observed that a higher infection rate was recorded in younger cattle (below two years of age) than older (above two years of age). Male cattle were more commonly affected than females. Snails belonging to genera Bulinus, Lymnaea and Planorbis were observed which are responsible for the transmission of paramphistomosis.Provedena su epizootiološka istraživanja paramfistomoze u goveda na klaonicama, farmama, veterinarskim klinikama i manjim gospodarstvima pod različitim uvjetima držanja i klime na području Punjaba. Invadiranost je istražena u četiri različite skupine goveda. Na klaonicama je pronađeno 7,83% invadiranih goveda, dok je na farmama taj broj bio nešto veći i iznosio je 12,33%. Među govedima na klinikama svega 7,17% životinja bilo je invadirano. Najmanji broj invadiranih goveda (4,25%) dokazan je u manjim gospodarstvima. U jesenjim mjesecima zabilježena je najveća učestalost u goveda s farmi (26%) i klaonica (14,50%). U goveda s klinika ljeti je dokazana učestalost od 9,75%. Najmanji broj invadiranih goveda dokazan je zimi u malim obiteljskim gospodarstvima (2,5%). Treba naglasiti da je najveća invadiranost zabilježena u goveda mlađih od 2 godine. Mužjaci su bili češće invadirani od ženki. Terenskim istraživanjima na istom području dokazani su posrednici, puževi iz rodova Bulinus, Lymnaea i Planorbis

Acaricidal and insecticidal effects of essential oils against ectoparasites of veterinary importance

Ectoparasitism in animals has become an issue of great concern that needs to be resolved to prevent huge economic losses occurring to livestock industry all over the world. Synthetic adrugs have been playing a major role in controlling ectoparasites, but their frequent and irrational use has resulted in drug resistance to routinely used chemicals and their residual effects on food and environment. Therefore, this approach of using chemical acaricides and insecticides is losing its popularity and effectiveness in controlling ectoparasites. So, the development of alternative approaches in ectoparasite management is currently required. Among alternative protocols, plants and their essential oils have played remarkable role in controlling different ectoparasites (ticks, flies, mites, lice) of veterinary importance. Essential oils have been proved to be cheaper, more effective and safer therapeautic agents against different ectoparasites of livestock importance

Role of Natural Antioxidants for the Control of Coccidiosis in Poultry

Avian coccidiosis is thought to be the one of the most expensive infectious diseases of poultry. Thus far, chemoprophylaxis and anticoccidial feed additives have controlled the disease but situation has been complicated by the emergence of drug resistant strains against commonly used drugs. Immunization by using vaccines has been another effective approach, but, in poorly managed poultry production systems particularly in case of broiler birds, vaccines may result in the onset of severe reactions. The other drawback of using vaccines is diversity of Eimeria strains in different geographical distributions. Therefore, vaccine strain, effective in one geographical area may not be effective in other area. A solution to these problems could be the use of antioxidant rich plant products that function by mechanisms other than those of chemotherapeutics, with the additional advantage of a natural origin. Antioxidant compounds could hold promise for the control of Eimeria infections due to the association of coccidial infection with lipid peroxidation of the intestinal mucosa. This paper reviews the research on naturally occurring antioxidants including botanical antioxidants effective against avian coccidiosis. Information regarding antioxidant activity, doses and mechanism of action of vitamin A, vitamin E, Zinc, Selenium and herbal complexes such as saponins, flavonoids, tannins, aromatic plants and their essential oils is provided in this paper, which may serve as new beneficial anticoccidial compounds and an essential component of alternative strategies for control of resistant Eimeria strains
