| Abstract | ||||
| Fifteen rams of three breeds, five Barki, five local Awassi and five imported Awassi breed were used in the present study. The study was aimed to investigate the effects of breed and seasonal vartanons on seminal plasma amino acids concentration throughout the experimental year. Results showed that there was a breed differences (p < O.01) in the concentrations of different amino acids. Glutamic acid (a non-essential amino acid) and threonine (an essential amino acid) were the predominant amino acids in all of the three studied breed. However, the concentration of the glutamic acid was significantly higher for local Awassi breed than the other two breeds. Threonine amino acid was significantly high concentration for the Barld rams than the other two breeds. In general it was found that total free amino acids in local Awassi seminal plasma significantly higher than in seminal plasma of the other two breed. This trend was also reflected on the essential and non-essential amino acids. Total free amino acids as well as the total essential ones were increased significantly during summer season as compared to the other seasons. On the other hand, total non-essential amino acids were significantly increased throughout spring months. The increased value was more pronounced in therionine in summer and glutamic acid in spring. 'Results also showed that Barki and local Awassi breed had higher values of total amino acids at summer time which may suggest their suitability for breeding at the semi-arid of the North West Coast of Egypt. | ||||
