“…The light duration in a lighting program is one of the most significant components of the poultry applications (Aldridge, 2019) and can also have varying effects on performance, broiler activity, growth development and physiological functioning (Hogshead, 2015;Olanrewaju et al, 2015). Researches on different light duration mainly focus on two forms of lightning: continuous lighting and intermittent lighting (Zhao et al, 2019). Application of continuous lighting and intermittent lighting programs do not constitue any different results in terms of body weight (Altan et al, 1998;Bolukbasi and Yilmaz, 2003;Rahimi et al, 2005;Ilhan and Yetisir, 2009).…”

“…(Altan et al, 1998;Bolukbasi and Yilmaz, 2003;Rahimi et al, 2005;Mahmud et al, 2011). According to Zhao et al (2019), the intermittent lighting has a significant effect on daily average feed intake of broiler chickens compared with constant lighting. Zhao et.al.suggest that the intermittent lighting might be beneficial to broiler chickens from 1 to 21 days of age.…”

“…* Significant at 0.05 probability level, ** Significant at 0.01 probability level. Zhao et al (2019), state that photoperiods and light intensities have no effect on average feed conversion ratio of the broiler chickens from 1 to 21 days of age. A similar result was obtained in the 3 rd week cumulative feed values in this study.…”

“…Although lighting program has been proven to have a significant effect on the mortality according to some studies (Classen et al, 2010;Brown, 2010;Ahmad et al, 2011;Maria et al 2011;Schwean-Lardner et al, 2013;Skrbic et al, 2015), it has not been examined in many studies in other respects.

“…Lighting, an extremely significant environmental and primary microclimate factor in poultry production, plays a pivotal role for the release of various hormones that influence growth, development and physiological functioning (Olanrewaju et al, 2006;Baser and Yetisir, 2010;Ahmad et al, 2011;Yang et al, 2015;Olanrewaju et al, 2016;Zhao et al, 2019). Physiological activities and behavioural processes of birds are externally controlled by lighting programs (Brown, 2010;Mahmood et al, 2014;Pandey, 2019).…”

The experiment was carried out to evaluate effects of point Light Emitting Diode (LED) lights source attached to the feeders and drinkers on the broiler performance compared with the standard ceiling with the bulb in environment controlled house with two clusters. Total of 3360 chicks were divided into 2 groups (control and experimental) consisting 3 replicates of 560 chicks with 12.5 birds/m 2 stocking density. Although, light intensity was measured as 18 lux at the level of feeders for the control group, it was measured 82 lux inside the feeders, 12 lux at the outer edge of them, while the measuring was showing 1 lux at 15 cm distance from the feeders 8 lux at the water dropper and zero in other areas for the experimental group. Standard rearing techniques and commercial diets were used during experimental period and parameters such as growth performance, feed conversion ratio (FCR) and mortality of broiler chicks were determined. The mean chick weight at the beginning of the experiment was similar in the control and experimental groups. There was no difference between lighting applications at the age of first week, however, at later stages, body weight (BW) was recorded significantly higher (P≤0.05, P≤0.01) in LED illumination treated group compared to control group. No significant differences were observed in feed intake and FCR between lighting treatments. In 42 day old, feed conversion ratios in control and LED lighting treated group were determined as 1.651 and 1.607, respectively (P>0.05). The mortality rates of control and LED lighting treated groups were found to be 5.24 and 3.51 (P≤0.05) at the age of 42 days. No negative effect of Point LED lights system on weekly body weight gain, feed intake, and feed conversion ratios were observed, but a positive effect on cumulative body weight and mortality. Therefore, pointed LED can be used as a lighting system in broiler production being cost effective without compromising the productive performance.

Adverse effects of heat stress during summer on broiler chickens production and antioxidant mitigating effects

et al. 2022

Broiler chicken meat is a good source of protein consumed universally, and is one of the most commonly farmed species in world. In addition to providing food, poultry non-edible byproducts also have value. A major advantage of broiler chicken production is their short production cycle, which results in a greater rate of production in comparison to other species. However, as with any production system, there are constraints in broiler production with one of the most pressing being energy requirements to keep the birds warm as chicks and cool later in the growth cycle, as a result of the cost needing mechanical heating and cooling. While this is feasible in more advanced economies, this is not readily affordable in developing economies. As a result, farmers rely on natural ventilation to cool the rearing houses, which generally becoming excessively warm with the resultant heat stress on the birds. Since little can be done without resorting to mechanical ventilation and cooling, exploring the use of other means to reduce heat stress is needed. For this review, we cover the various factors that induce heat stress, the physiological and behavioral responses of broiler chickens to heat stress. We also look at mitigating the adverse effect of heat stress through the use of antioxidants which possess either an anti-stress and/or antioxidant effects.
