“…Забезпечення захисту свиней, підвищення неспецифічної резистентності організму і продуктивного потенціалу до стресових впливів є одним із головних завдань ефективності галузі свинарства (Solà-Oriol, & Gasa, 2017;Lee et al, 2016;Chowdhury, Haque, Islam, & Khaleduzzaman, 2009;Danchuk, Karpovskyі, Trokoz, & Postoі, 2017). До факторів, що стримують розвиток свинарства слід віднести незаразні хвороби, на частку яких припадає 60-80 % випадків захворюваності через недотримання мікроклімату (Cherny, Shchepetilnikov, Mytrofanov, & Machula, 2019;Lukashchuk, Slivinska, & Shcherbatyy, 2018;Pluske, Turpin, & Kim, 2018), порушення режимів годівлі та напування (Lykhach, Lykhach, Ivanov, & Zasukha 2017;Krempa, Kozenko, & Chornyi,2020), адинамії і гіпоксії, раннього відлучення поросят і перегрупувань, високої контамінації повітря мікрофлорою (Rybachuk, Galatyuk, & Romanyshyna, 2019) і недотримання принципу «все порожньо-все зайнято», а також неповноцінної годівлі (Grushanska, & Kostenko, 2017;Krempa, & Kozenko, 2018). Досліджень щодо так званих «факторних інфекцій» або «патологій високих технологій», як зараз озвучують, недостатньо, хоча вони і завдають значної шкоди інтенсивному свинарству.…”

“…3 ), через 4-6 год проявляється гіпоглікемія, вони можуть смоктати свиноматку лише 6-8 разів на добу замість 22-28 разів і у неї розвивається мастит. У сисунів знижуються на 15-20 г СДП на кожен градус при температурі повітря нижче + 15 °C, а споживання корму підвищується (Cherny, Shchepetilnikov, Mytrofanov, & Machula, 2019;Jayaraman, & Nyachoti, 2017;Einarsson, Brandt, Lundeheim, & Madej, 2008).

Data on the role of ensuring and maintaining comfortable hygienic parameters, sanitary regimes and technological methods aimed at realizing the genetic productive potential, reducing morbidity and safety, as well as increasing the resistance of the pig's organism under conditions of their intensive use in industrial complexes was summarized in this article. We emphasized that under the conditions of pig breeding, the genetic productive potential is practically realized only by 40 %, due to non-observance of the hygiene condition of keeping and technology of growing. We are talking about the genotypes of domestic breeding pigs, which are actively replaced by breeds of foreign companies, while, under equal conditions, they are not inferior to those imported from abroad, neither in terms of productive qualities, nor in terms of reproductive and adaptive abilities.It has been shown that the air temperature has the greatest effect on the animals' health among all abiotic factors, especially on sucker piglets, at a temperature of + 12 ° C and a humidity of 80% and above, as well as when the air is contaminated with microflora over 100 thousand CFU/m 3 we diagnosed hypoglycemia. In addition, pig breeding farms are unsafe in sanitary and environmental terms.Aerostases (stagnant zones) often registered in pigs ' farm, due to unregulated ventilation, 25-30 % in 2-row and up to 35-40 % in 4-row barn. The average daily gains decrease by 7-12 %, the milk production decreases by 10-13 % due to the lack of free access of pigs to water. Success in pig breeding is ensured by replacement young animals raised on their own farm, and not imported from other countries.Attention should be focused on prevention of early weaning of piglets (live weight not less than 7 kg at 24-28 days of age), regrouping, movement, which leads to the manifestation of stress, diarrhea, growth depression. Prevention of respiratory diseases is based on strict sanitation, adherence to the principle "everything is empty -everything is busy" and maintaining sanitary breaks. According to our research in a number of pig breeding farms more than 23% of sows are prematurely culled after 2-3 farrowings due to, infertility, limb diseases.

The results of the experiments were used to evaluate the morphological and protein composition of blood, as well as the quality of meat from pigs of different stress resistance. The studies were carried out under the conditions of PJSC ‘Stepovyi’ in Zaporizhzhia Region on Large White (LW) pigs and Large White/Charcoal Landrace (LWCL) crossbreeds. During the study period, the hygienic conditions of keeping, feeding and watering of the animals, their growth and development, clinical condition and morbidity were evaluated. After reaching a live weight of 100 kg, the pork meat quality (pH, moisture content, oxyproline, tryptophan) of slaughtered animals was studied. It was found that the LW genotypes were superior to the local LWCL by the number of leukocytes in passively resistant (PR) animals — by 2.7%, in stress resistant (SR) animals — by 3.15%, and in stress sensitive (SS) animals they were inferior by this indicator by 7.7%. There was no significant difference in erythrocyte content between SR and SS, but erythrocyte content was 8.53% lower in PR. The concentration of hemoglobin was higher in PR animals of the Large White cross. The latter were superior to LW in terms of total protein: PR — by 2.26%, SR — by 1.9%, in terms of albumin — PR had an advantage of 16.6%, SR — by 7.69% (p < 0.05). Gamma globulin content was 6.44% lower in SS animals. They were superior to LW in terms of live weight: PR — by 14% at one month of age; by 4.2% at four months of age, SR — by 6.2%, but the difference between SR and SS was not significant. PR animals of the Large White breed were superior in terms of hemoglobin content. The level of total protein in blood serum was higher in crossbred genotypes: in PR — by 2.26%, in SR — by 1.9%. The concentration of albumin was higher in the crossbred animals than in the LW: PR — by 16.6%, SR — by 7.69%, and the level of gamma globulins was 6.51% lower in the SS. In terms of live weight, crossbred genotypes outperformed LW: passive resistant genotypes — by 14% at one month of age, stress resistant genotypes — by 6.2% and 4.2% at four months of age. The crossbred genotypes reached 100 kg live weight: PR — at 180 days, SR — at 183 days, SS — at 191 days, which is 4, 5, and 12 days earlier than LW, respectively. In crossbred pigs, the positive correlation for thoracic girth was 0.6942 and 0.8310, and for withers height — 0.6643 and 0.6811. In terms of body length, animals of the crossbred genotype were superior to LW: PR by 4.2%, SR by 1.46%, while the difference in chest girth and body length in SS individuals was not significant. Lung weight was 0.84% higher in PR and 3.7% higher in SR, and kidney weight was 9.8% higher in PR, 6.56% higher in SR, and 1.37% lower in SS. LW animals were superior in heart weight. Behavioral responses (fighting, skirmishing) were more pronounced in the crossed genotypes, especially in SR and SS animals. A higher level of tryptophan was found in the meat of SR crossbred animals, oxyproline — in PR and SR, pH of meat — in Large White PR and SR ranged from 5.61 to 5.72 units, in crossbred animals this indicator did not exceed the values of 5.03–5.21 units. Defects in meat with PSE (pale, soft, exudative) signs of LW were found: in PR — 0.4%, SR — 0.63%, SS — 3.7%, and in LWCL respectively — 2.3%, SR — 2.1%, SS — 4.21%, in local — defects in meat with DFD (dark, firm, dry) signs were manifested in 3.1%, 2.15%, and 5.1%
