“…Insufficient practical application of semen cryopreservation and artificial insemination of birds, which is partly due to the low efficiency of existing methods of freezing ejaculates, is a constraint on the development of the poultry industry (Dimitrov, Atanasov, Surai, Denev, 2007;Donoghue, Wishart, 2000;Douard, Hermier, Magistrini, Blesbois, 2003). In the process of freezing and thawing of ejaculates of birds a sharp decrease in physiological characteristics of spermatozoa is observed that is explained by a high level of damage of plasma membranes of sexual cells of birds (Fattah, Sharafi, Masoudi, Shahverdi, Najafi, 2017;Froman, 2003;Hudson, Omprakash, Premavalli, 2016). First of all, it indicates the imperfection of existing technological approaches and applied diluents for bird ejaculates (Iaffaldano, Meluzzi, 2003;Kotlowska, Dietrich, Wojtczak, Karol, Ciereszko, 2007;Kucera, Heidinger, 2018).…”
