Abstract Farm diversification is mainly driven by risk mitigation effects and economic gains related to complementarities between production activities. By combining these two aspects, we investigate economies in a sample of French mixed sheep farming systems rank using stochastic dominance criteria. Partially diversified (Sheep-Grass, Sheep-Crop, Sheep-Landless) fully (Sheep-Grass-Crop-Landles...

genetic improvement programs may improve disease resistance in animal production. the best-characterized genetic control of disease resistance and immune response in animals is the one associated with the major histocompatibility complex (mhc). the ovine lymphocyte antigenof drb1 gene encodes cell surface glycoproteins that initiate immune responses by presenting processed antigenic peptides to...

b ackground : anaplasma ovis infections can cause clinical symptoms in acute phase and lead to huge economic losses in flocks. the aim of the present study was to investigate the hematological and par- asitological changes in experimental anaplasmosis in sheep with iranian strain of a. ovis . m ethod: five male sheep without any blood parasite infection were selected. one hundred ml hepa-rinize...

BACKGROUND Olive trees (Olea europaea subsp. europaea var. europaea) naturally grow in areas spanning the Mediterranean basin and towards the East, including the Middle East. In the Iranian plateau, the presence of olives has been documented since very ancient times, though the early history of the crop in this area is shrouded in uncertainty. METHODS The varieties presently cultivated in Ira...

Cerebral coenurosis is the intermediary larval stage of Taenia multiceps, which affects intermediate hosts, particularly sheep and goats. In this report, gross and microscopic features of three scarce natural coenurosis cases, a one-year-old ram and two lambs of 7 month old from a flock are explained. At necropsy, numerous small cysts measuring 5 to 10 mm in diameter were observed on both cereb...

Background: Hydatidosis is a neglected cyclo-zoonotic disease in Middle East countries particularly southeast of Iran which is caused by metacestode of tapeworm Echinococcus granulosus sensu lato. Human hydatidosis is a high public health priority in the area, however there is little known from a phylogenetic perspective on molecular epidemiology of adult Echinococcus spp. in Iranian shepherd d...

INTRODUCTION At the modern age, to acquire knowledge and experience, the individuals with their own specific culture have to enter contexts with cultural diversity, adapt to different cultures and have social interactions to be able to have effective inter-cultural relationships.To have such intercultural associations and satisfy individual needs in the society, cultural intelligence and social...

INTRODUCTION Quoting an article in well-known textbooks is held as a credit for that paper. The numbers of Iranian publications mentioned in endodontic textbooks have increased during recent years. The aim of this investigation was to evaluate the number of Iranian articles quoted in eminent endodontic textbooks. METHODS AND MATERIALS Three known textbooks (Ingle's Endodontics, Seltzer and Be...

The families of TGF-β proteins are the most important growth factors in the ovary for growth and differentiation of early ovarian follicles. Three related oocyte-derived members of the transforming growth factor-β superfamily namely growth differentiation factor 9 (GDF9), BMP15 and BMPR-IB have been shown to be essential for follicular growth and ovulation. Different mutations in the GDF9 gene ...
