This review focused on highlighting the importance of the biochemical role of some additives that have a stimulating impact on in vitro maturation (IVM) of farm animal oocytes. The supportive role that these additives played has led to a noticeable increase in embryos yields. Nevertheless, there are some considerations that must be taken into account for the process of producing embryos in vitro to function optimally. Among the hormones, the famous gonadotropic hormones (follicle-stimulating hormone (FSH), luteinizing hormone (LH) and chorionic gonadotropin hormone (CG)), estradiol and growth hormone (GH) occupied a wide area in IVM, but the usage of these hormones still limited to specific concentrations as the increase in their concentrations did not give the desired effect. Due to the historical popularity and the primary role of cysteamine as an antioxidant agent, its usage has increased recently. However, this usage has also remained limited to specific concentrations, as are hormones. Besides, cysteamine was an important reason for obtaining high rates of embryos in the blastocyst stage. Conversely, there was a reservation in the use of follicular fluid (FF) and fetal calf serum (FCS). Although these two elements are rich in hormones, proteins, lipids and various growth factors, FF contains factors that inhibit the maturation of oocytes. Moreover, FCS has a negative role in the quality of resulted embryos because of the high levels of lipids (triglycerides).

Iraq and Syria are among the countries that are frequented by wild birds in great numbers and species due to the abundance of water, green spaces, moderate climate in winter and the lack of predators. The two countries fall under the migration line of birds that stretches between East Asia and East Africa. The results of the survey, which were conducted nearly twenty years ago, indicated that there are at least 400 species of migratory birds coming to Iraq and Syria (The majority are from the Accipitres (Accipitridae) and passerines (Passeriformes)). In Iraq, the marshes (Al-Ahwar) are inhabited by species of birds that are rare in other parts of the world like the Iraq Babbler (Turdoides squamiceps) and the rocking reed of Basra (Acrocephalus griseldis). The rare endangered Namaqua Dove (Oena Capensis) was seen in the Syrian Badia.  Recently, the status of the deputed birds has decreased in terms of numbers and species due to a set of reasons, the most important of which is the phenomenon of over-hunting, which has negatively affected the numbers of birds, especially birds that are threatened with extinction and included in the red list such as the Ferruginous duck (Aythya nyroca) and the Eurasian teal (Anas Crecca). The demographic fluctuation and war conditions have led to the reluctance of some species to come to Iraq and Syria and change the course of their migration to other places. The emergence of some non-traditional methods of hunting by bird hunters, such as the establishment of artificial waterbodies to attract waterfowl, led to an unprecedented decline in the numbers of these birds. The lack of legal oversight, lack of accountability, and the tendency of bird hunters to hunt in uncontrolled areas increased the great damage to wild birds in particular and to wildlife in general.

The research was conducted at the Research Center of Agriculture Faculty of the University of Aleppo. 240 chickens of Babcock B300 strain were used and distributed randomly from day one into four independent groups. Each group included 60 birds distributed into three replicates (20 birds). The control group (A group) was fed a balanced standard feed mixture (1-18 weeks) without additives, while lactic acid bacillus was added to treatments groups according to three levels (50 mg/kg feed; B group, 100 mg/kg feed; C group and 150 mg/kg feed; D group). Haematological analyzes were performed over two- time intervals (1-21 weeks and 22-32 weeks). In the first time interval, results showed that a rise in blood albumin (P<0.001) was also observed in C and D groups compared to the A group. The rates of blood globulin increased (P<0.02) in the D group compared with the rest of the groups. No significant differences were noticed across the various groups for the total number of white blood cells and lymphocytes rates. In the second time interval (productive stage), significant differences (P<0.01) were noticed across the various groups in the percentages of the total protein (the highest value was 4.75 g/dl; B group) and serum albumin (the highest value was 3.26 g/dl; D group). It is concluded from the current study that the addition of probiotics to the mixtures of laying hens had a significant improvement in the immune parameters in the blood.
