THO Complex 5 (THOC5) gene involves in lipid and fatty acid metabolism. The aim of this study was to analyse polymorphism THOC5 its association with composition sheep. A total 120 rams at the age 12 month average body weight 25–30 kg used for identification using Polymerase Chain Reaction- Restriction Fragment Length Polymorphism (PCR-RFLP). 83 rams, representative from different genotypes shee...

Quantitative microscopic structure of testis in adult Arabian rams, raised under closed grazing system in Khuzestan province of Iran, was studied in four seasons over a one year period. For this purpose, thirty adult rams were randomly selected and the live weight and scrotal circumference of rams were recorded. At the beginning of each season, among the study group, four rams were randomly sel...

The present experiment was designed to investigate the subsequent influences of supplementing different levels of intact green seaweed Ulva lactuca (0%, 3%, and 5% DM) to growing sexually immature lambs during the growth period (74 d) on the seminal and testicular characteristics of sexually mature rams. Ulva lactuca was manually collected, adequately prepared, and then incorporated into lambs'...

There is strong evidence that the gonads modulate the hypothalamic-pituitary-adrenal axis. To investigate these sex differences at the adrenal glands of sheep we compared the cortisol response to ACTH (experiment 1) and measured the relative expression of oestrogen receptor alpha (ERS1), androgen receptor (AR), melanocortin 2 receptor (MC2R) and steroid acute regulatory protein (STAR) mRNA in a...

Studies over 3 years showed that testicular volume falls during summer and autumn when forage quality and availability decline and when rams are mating. Loss in testicular size may also occur in summer in the absence of mating activity and at a greater rate than loss in live weight. The results suggest that mating and nutrition may override the influence of photoperiod on testicular size and th...

In recent years awareness of the importance fatty acid composition ruminants meat and milk products has increased, with a particular emphasis on n-3 polyunsaturated acids, for example, eicosapentaenoic (EPA; C20:5 n-3) docosahexaenoic (DHA; C22:6 n-3), as these can have beneficial effects animal performance reduce risk coronary heart disease in humans. The aim this study was to investigate feed...

Reliability, availability, maintenance and safety (RAMS) analysis is essential in the evaluation of safety critical systems like nuclear power plants and the railway infrastructure. A widely used methodology within RAMS analysis are fault trees, representing failure propagations throughout a system. We present DFTCalc, a tool-set to conduct quantitative analysis on dynamic fault trees including...

The purpose of this work is to study the Etesian winds in the Saroniko Gulf to understand the complicate physical processes that generate the windstorms in the Saroniko Gulf. It is developed a study of the weather patterns characteristic of the Saroniko Gulf and a comparisons of the wind data measured on land by the station of Helliniko airport (years: 1990–2000) and at sea by a buoy (years: 20...

A technique for cannulating the external spermatic artery was developed and used, together with Krypton-85 clearance, to show that there are two compartments of blood flow (the fast and the slow) in the one region of scrotal skin of Merino rams selected for (Folds Plus) and against (Folds Minus) skin fold. The rate of blood flow of the fast compartment was seven to eight times faster than that ...
