Early growth traits in sheep are economically important. Breeding for these traits has been shown to be problematic using quantitative genetic methods, particularly in native sheep herds. Molecular genetics is useful for sheep breeding. The gene for insulin-like growth factor 1 (IGF1) is one of the important candidate genes known for ovine early growth traits. The aim of this study was to inves...

assessing genetic diversity in eight indigenous iranian sheep breeds (ovis aries) using aflp markers
in this study genetic diversity of eight iranian sheep breeds including; lori bakhtiari, makuei, moghani, taleshi, shal, zandi, naeini and kalakui was studied by using aflp method. a total of 309 individuals were analysed that produced 121 clear polymorphic bands. the average of heterozygosity within breed (hs) was high and equal to 0.2795± 0.0255. also, the average heterozygosity between breed...
the aim of this study was to determine the effects of ecg, pgf2α and gnrh hormone on improvement of reproduction performance of cidr synchronized zandi ewes in breeding season. 500 ewes with age of 2.5-4 years and same nutritional condition were selected for this study and received cidr for 12 days. then these ewes were assigned to five equal groups. first group received no hormone (control gro...

Introduction: Microorganisms may be present in the form of spores, in honey. One of these dangerous organisms is the bacterium Clostridium botulinium spores which are capable induced botulism particularly in infants. The aim of this study was to determine the prevalence of Cl. botulinum spores in honey produced in different regions of Iran. Method: This cross-sectional study was performed in...
Background: The application of laparoscopic method for intrauterine insemination is limited in sheep industry by the high cost of equipment and low pregnancy rate of frozen-thawed spermatozoa. Both disadvantages could be decreased if chilled ram semen is transported to the farms and inseminated through cervix. Semen extender provides the requirements for sperm and affects its motility, viabilit...
introduction it has been estimated that pbp production based on fresh weight in iran is over 400,000 mt annually. pistachio by-products consist of 53.50% external hull (epicarp) with the remaining composed of leaves, mesocarp and kernel. the results of few studies showed feeding of low levels of pbp had no effects on sheep, dairy cow and goat performance. ensiled of pbp with peg, naoh and urea ...
objective: the effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. materials and methods: in this experimental study, we randomly assigned 9 zandi rams to two groups (isoenergetic and isonitrogenous diets): control (ctr...
