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 artificial insemination and semen sam...
The aim of this study was to evaluate the effects of the addition of antioxidants (vitamin E, β- mercaptoethanol and their combination) to semen extender. Progressive motility, viability and pH of fresh ram semen were examined. Ejaculate samples were collected with artificial vagina from three Ghezel-Merinose rams (3 years old) during non- breeding reproduction season. Semen was diluted with a...

the aim of this study was to evaluate the effects of dilution rate and holding time on various motility parameters using computer-assisted sperm analysis (casa). the semen samples were collected from three ghezel rams. samples were diluted in seminal plasma (sp), phosphate-buffered saline (pbs) containing 1% bovine serum albumin (bsa) and bioexcell. the motility parameters that computed and rec...
this study was conducted to evaluate effects of rosemary essential oils (reo) on feed digestibility, blood and rumen parameters of ghezel sheep. four male sheep with average body weight 46±2 kg were used in a 4×4 latin square design. treatments composed of basal diet (control) in addition to diets containing 100 (ro100), 200 (ro200) and 400 (ro400) mg/day of reo. sheep's fed with 4 diets ...

To compare the relative value of the fish meal and the cottonseed meal in highly fermentable diets (40% forage and 60% concentrate with), eight cows were assigned randomly to diets with 0, 1.5, 3 and 4.5 percent of the fish meal. In the first experiment, the degradability of dry matter and crude protein of the fish meal, the cottonseed meal and concentrate in diets was estimated with different ...
Prioritization of watershed basins includes classification of sub-basins on the basis of the existing conditions and erosion intensity, which ultimately leads to protective operations and watershed management in more significant and susceptible sub-basins. In this research, in order to prioritize Ghezel Owzan-Sefidrud sub-basins against sensitivity to erosion, linear and form-based morphometric...
