Previous work has shown that exposing broiler eggs to white light during incubation can improve hatchability and post-hatch animal welfare. It was hypothesized that due to how different wavelengths of light can affect avian physiology differently, and how pigmented eggshells filter light that different monochromatic wavelengths would have differential effects on hatchability and post-hatch animal welfare indicators. To determine, we incubated chicken eggs (n = 6912) under either no light (dark), green light, red light or white light; the light level was 250 lux. White and red light were observed to increase hatch of fertile ( P < 0.05) over dark and green light incubated eggs. White, red and green light exposure during incubation improved ( P < 0.05) the proportion of non-defect chicks over dark incubated eggs. Post-hatch 45-day weight and feed conversion was not affected by light exposure of any wavelength ( P > 0.05). Fear response of during isolation and tonic immobility was reduced ( P < 0.05) in broilers incubated under white or red light when compared with either green or dark broilers. Broilers incubated with white or red light had lower ( P < 0.05) composite asymmetry scores and higher ( P < 0.05) humoral immunity titers than dark incubated broilers, however, green light broilers did not differ ( P > 0.05) from dark incubated broilers. All light incubated broilers had lower ( P < 0.05) plasma corticosterone and higher ( P < 0.05) plasma serotonin concentrations than dark incubated broilers. These results indicate that white light and red light that is a component of it are possibly the key spectrum to improving hatchability and lower fear and stress susceptibility, whereas green light is not as effective. Incubating broiler eggs under these spectrums could be used to improve hatchery efficiency and post-hatch animal welfare at the same time.

Horse transportation for temporary relocation during rest periods is a common and widespread practice among horse owners, either from sport competition or working tasks. This study aimed to determine the effect of a relocation period and the multiple factors associated with a rest period on hair cortisol concentrations (HCCs) in horses. Additionally, this study reports the seasonal effect on HCCs and hair growth over a year. Thirteen police horses, Pure Spanish stallions of various ages (5–13 y), were selected to participate in this study. Hair sample collection was carried out approximately every 30 d for seven months (Study 1) and a year (Study 2). Cortisol determinations were performed by enzyme immunoassay. Interestingly, Study 1 revealed that relocated horses (n = 4) exhibited elevated HCCs compared with control horses (n = 4) after the relocation period (p < 0.05). Study 2 (n = 5) showed higher HCCs during summer compared with autumn and winter, and higher hair growth rates in winter compared with the other seasons (p < 0.05). Relocated horses had higher HCCs, suggesting a change in their welfare status, probably related to the sudden change in their surrounding conditions. However, these results should be interpreted cautiously due to the low sample size used. The nature of the relationship between HCCs and horse welfare needs to be further examined.

Тому, сьогодні настала нагальна необхідність впровадження нових ресурсоощадних технологій, які б за рівнем виробництва відповідали європейським вимогам (Lutsenko and Sameha, 2007;Grainger et al, 2008;Ghassemi Nejad et al, 2017).…”

High productivity of dairy cows in the conditions of new innovative technologies can not be obtained without providing comfortable conditions for their functioning.In this connection, the conditions for maintaining high-yielding cows in various types of livestock buildings are investigated: the traditional, 24.0 m wide and new unassembled, 32.5 m wide and 36.0 m in extreme periods of the year. The different width of the premises is due to the need to use different types of milking plants: MilkProud, Parallel, Carousel and robotic milking systems.Studies have established that volumetric-planning and technological solutions for easy-assembled premises increase the volume of space per head from 45.6 m3 to 96.3 m3 and 129.6 m3. It positively affects the conditions for the maintenance of highly productive cows. The presence in their design of side curtains and light-aeration ridge increases the speed of air in 3 times. This provides a reduction in the concentration of ammonia in 8 times, and bacterial pollution at 18.7 times compared with traditional barn.Increasing the volume of the room up to 129.6m³ per head reduces the bacterial air pollution in the winter period to a minimum value of 2.8 thousand/m³. New elements in the design of easy-assembled spaces provide resource-saving and organizing their lighting.According to the existing standards in Ukraine, the lighting in the feeding area should be at 52 lux. In traditional rooms, this level is achieved only by installing additional energy sources, which provide an increase in lighting from 31 lux to 52 lux. In new types of premises the required level of lighting is provided naturally, which leads to significant energy savings. It was established that technological solutions of easy-assembled premises provide comfortable conditions for recreation of high-yielding cows.In these types of rooms, the animals rest 12.4% and 20.0% more time compared to traditional rooms. Feeding of cows in easy-assembled premises from the stern table provides quick feeding of animals with feed. At the same time the time consumed for feed consumption in new types of barns is significantly less and is 252.0–246.0 min a day compared to 320.2 min in traditional premises where feeding is carried out from traditional feeding troughs.It is positive that in the new types of premises in animals there is a new important element of behavior – the movement, which they spend 8.6% and 9.9% of the time. New types of premises with resource-saving milk production technologies have a positive effect on the conditions for the maintenance of highly productive cows and can be widely implemented in Ukraine.
