In the presence of Professor Dr. Hussam Jassim Bananah, the head of the Department of Animal Production, and a number of faculty members from the Department of Animal Production, Dr. Sajida Mahdi Eidan delivered a lecture on her published research titled ‘The Effect of Sil-Select and Swim-Down Techniques with Antioxidant Added to Extender on Semen Quality of Iraqi Buffalo Bulls.’ The research aimed to:

  1. Investigate the impact of using Swim Down and Sil-Select Plus techniques to separate poor-quality sperm in Iraqi buffalo bulls on semen quality after separation.

  2. Study the synergistic effect of adding antioxidants (glutamine and arginine or vitamins E and C) to the sperm extender filtered by Swim Down and Sil-Select Plus techniques on the semen quality after freezing.

The researcher recommended using Swim Down and Sil-Select Plus techniques with or without antioxidants to obtain the highest percentage of normal sperm with lower overall sperm deformities in Iraqi buffalo bulls. Additionally, these techniques aim to reduce the time required for sperm separation to enhance other sperm characteristics.

Professor Dr. Ziad Tariq Al-Dinkie gave a lecture on his published research titled ‘Effects of Modified Atmosphere Packaging Nitrogen Gas in Storage Ross 308 Broiler Hatching Eggs on Eggshell Conductance Values and Some Hatchability Traits.’ The research aimed to extend the storage period of broiler hatching eggs by reducing the gas permeability of the eggshell using nitrogen gas. The researcher recommended applying nitrogen gas pressure to hatching eggs, which could significantly prolong the storage period by more than 14 days, with a meaningful increase in the hatchability rate of fertilized eggs.

Assistant Professor Basam Ghazi Al-Khatib presented his first published research on ‘Genotyping of TSH-Β Gene G >141A Associated with Some Productive and Physiological Traits of Local Iraqi Chicken.’ The research aimed to identify the genetic structures and allelic variations of the targeted gene and study their impact on the productive and physiological performance of local Iraqi chickens. The study revealed a significant effect of different structures of this gene on most production traits, such as weight, age at sexual maturity, and egg mass production. The researcher recommended using this gene and its genetic structures in molecular genetic selection processes to improve local Iraqi chickens.

In his second published research, ‘Presence and Absence of Quantitative Traits Loci (QTL) Region on Chromosome Z and Its Effect on Some Productive and Physiological Traits in Local Iraqi Chicken,’ Dr. Basam Ghazi Al-Khatib aimed to molecularly study quantitative traits loci (QTL) on Chromosome Z, tracking genetic mutations and their impact on the productive and physiological performance of local Iraqi chickens. The study indicated a wide range of genetic variations affecting egg weight and some qualitative traits. These findings can be crucial for future development of a local strain in Iraq based on molecular technologies.

Our best wishes to everyone for success and continuous dedication in service to the department and the college…
