Five chicks (2–6 weeks of age) were taken randomly from each of 218 broiler farms in Tabriz northwest of Iran. These chicks were submitted for post-mortem and parasitological examinations. Five Eimeria spp. were identified: E. acervulina, E. tenella, E. necatrix, E. maxima and E. mitis. The overall prevalence of Eimeria spp. among examined farms was 55.96 %(More)
Changes in selected blood and serum components and electrocardiography (ECG) were investigated in 20 adults (13 females and 7 males) of water buffaloes suffering from severe theileriosis. The age of all animals used in this study ranged 1.5-5 yr. Theileriosis was diagnosed by observation of parasites in the peripheral blood and the presence of schizonts in(More)
Nestin, an intermediate filament protein is expressed by neuroectodermal stem cells and tumors originating from cells of neuroectodermal and mesenchymal lineages. Nestin expression is prominent in embryos and remains upregulated until 3–6 weeks after birth but is downregulated afterward. Sertoli cells are nucleated somatic cells that are spanned in the(More)
Thin ewes or very over-conditioned ewes and ewes carrying multiple pregnancies are more likely to develop pregnancy toxemia (ketosis). Pregnancy toxemia is a metabolic disorder characterized by hypoglycemia and hyperketonemia resulting from incapacity of the ewes to maintain adequate energy balance (usually in the last 5-6 weeks). Available information(More)
Genetic variation among sheep breeds in resistance to gastrointestinal nematodes (GIN) has been demonstrated in several production environments. Relationships between the ovine major histocompatibility complex and resistance to GIN have been studied, but few studies have systematically examined this issue in less-developed and semi-arid regions. The aim of(More)
Spermatogonial Stem Cell (SSC) technologies provide multiple opportunities for research in the field of biotechnology and regenerative medicine. The therapeutic use of Embryonic Stem Cells (ESCs) is restricted due to severe ethical and immunological concerns. Therefore, we need a new pluripotent cell type. Despite well-known role of germ cells in the(More)
Applying a multiple trait random regression (MT-RR) in national level and for whole test day records of a country is a great advance in animal breeding context. Having reliable (co) variance components is a critical step in applying multiple traits genetic evaluation especially in developing countries. Genetic parameters of milk, fat and protein yields were(More)
This study was conducted to determine the combined effects of adding vitamin E (VitE) and selenium nanoparticle (Nano-Se) as antioxidant supplements to rooster semen extender for freezing. Semen samples were collected from 12 White Leghorn roosters and pooled. Subsequently, the samples were divided into nine equal groups using modified Beltsville extender.(More)
Background: Measurements of testosterone, scrotal circumference and libido have a great value as indicators of onset of puberty, total semen production, semen quality, control of spermatogenesis, testicular state, pathological conditions of testes and the potential sub-fertility or infertility. Therefore, the aim of this study was to determine relationship(More)
Semen collection evaluation and addition of preservatives to increase storage period of sperm are essential for successful artificial insemination. This study was conducted on 4rams (2 Ghezel Merinos and 2 Merinos Moghani) to evaluate the effect of two diluents in Khalatposhan research station. Average age of rams was 3 years. Rams were trained to serve the(More)
