Изучено влияние различных режимов фотопериода красного монохроматического светодиодного освещения яиц в условиях искусственной инкубации на рост, развитие висцеральных органов, гематологический профиль крови, уровень стресса, метаболизм эмбрионов кур и результаты инкубации яичного кросса «Ломанн Браун». На 21-е сутки при 24-часовом световом режиме у эмбрионов отмечалось увеличение длины и массы тела, мышечного желудка, печени, селезенки, а при 18- и 12-часовом режимах – массы тела, мышечного желудка, печени, селезенки. При отсутствии света и 12-часовом световом режиме у эмбрионов наблюдались выраженная лимфоцитопения и нейтрофилия, а также повышение уровня стресса. При 24- и 18-часовом режимах интенсивность дыхания и уровень базального метаболизма у эмбрионов на 21-е сутки развития возрастали по сравнению с развивающимися эмбрионами в отсутствие света и при 12-часовом световом воздействии. Наши исследования свидетельствуют о превосходстве 24- и 18-часового светового режима по количеству выведенных цыплят по отношению к контролю и 12-часовому освещению. Вывод цыплят при этих продолжительных световых режимах был достоверно выше, чем в отсутствие света и при 12-часовом освещении, на 1,99–2,33 п. п. и 4,99–5,33 п. п. соответственно, а выводимость яиц – на 2,16–3,32 п. п. и 3,68–4,84 п. п. Самая высокая эмбриональная жизнеспособность в течение 19–21-х суток выявлена при круглосуточном освещении, а наиболее высокая гибель плода – при 12-часовом освещении. Таким образом, полученные данные указывают на то, что в практике инкубаториев при инкубации яиц кросса «Ломанн Браун» целесообразно использовать непрерывное красное светодиодное освещение, которое способствует интенсивному развитию эмбрионов и их висцеральных органов (мышечный желудок, печень, селезенка), стрессоустойчивости, оптимизации метаболизма, а также повышению вывода цыплят и выводимости яиц.

The effect of various photoperiod modes of red LED lighting on eggs under incubation on the growth, development of visceral organs, hematological profile of blood, stress level, metabolism, chicken embryos and results of incubation of egg of Lohmann Brown cross has bee studied. On the 21st day, with a 24-hour light mode, embryos showed an increase in body length and weight, muscle stomach, liver and spleen, and at 18- and 12-hour mode – body weight, muscle stomach, liver and spleen. In the absence of light and 12-hour light mode, embryos showed lymphocytopenia and neutrophilia, and increased stress levels. At the 24- and 18 hours modes, the intensity of respiration and level of basal metabolism in embryos on the 21st day increased compared to developing embryos in the absence of light and with 12-hour light impact. The 24- and 18-hour modes were superior in terms of number of chickens bred compared to control and 12-hour lighting mode. The hatching under prolonged light was significantly higher than in absence of light and under 12-hour illumination by 1.99–2.33 p.p. and 4.99– 5.33 %, and hatchability – by 2.16–3.32 p.p. and 3.68–4.84 %. The highest embryonic viability during 19–21 days was detected with round-the–clock lighting, and the highest fetal death was detected with 12-hour lighting. Thus, in the practice of incubation of eggs of the Lohmann Brown cross, it is advisable to use continuous red LED lighting, which contributes to intensive development of chicken embryos and visceral organs (muscle stomach, liver and spleen), stress resistance, optimization of metabolism, increased hatching and hatchability.
