“…The FCR showed a linear or quadratic ( P < 0.05) increasing response to increasing temperature. Our results were partly supported by previous studies in broilers ( Sohail et al, 2012 ; Zhang et al, 2015 ; Yi et al, 2016 ; Sahin et al, 2017 ; He et al, 2018 ; Ma et al, 2018 ; Song et al, 2018 ) and ducks ( Sun et al, 2019 ; Xie et al, 2019 ), which showed that high ambient temperature depresses feed intake, body weight, and weight gain. When ambient temperature is higher than the thermoneutral temperature, it can lead to higher body temperature and, thus, heat burden.…”

“…Birds subjected to high ambient temperature are characterized by altered physiology, behavior and performance ( Wasti et al, 2020 ). Specifically, high ambient temperature reduced feed intake and body weight gain, increased feed conversion ratio ( FCR ) in broilers ( Quinteiro-Filho et al, 2010 ; He et al, 2018 ; Ma et al 2018 ) and ducks ( Sun et al, 2019 ; Xie et al, 2019 ). Similarly, high ambient temperature decreased body antioxidant capacity ( Sahin et al, 2017 ), nutrient absorption and intestinal immunity ( Yi et al, 2016 ), impaired intestinal morphology ( Song et al, 2018 ), deteriorated carcass quality in broilers ( Zhang et al, 2012 ), and reduced breast and leg meat yield of growing White Pekin ducks ( Sun et al, 2019 ; Xie et al, 2019 ).…”

“…The optimal performance temperature for growing broilers has been reported to range from 18 to 24°C ( Saleh et al, 2021 ). In Pekin ducks, the upper critical ambient temperatures for starter ducks and growing ducks were 31.3 and 27°C, respectively ( Sun et al, 2019 ; Xie et al, 2019 ).…”

“…This categorisation needs be accepted with some scepticism as ducks may be more heat tolerant than are broiler chickens. The upper critical temperature during the growing period for LW, LWG and feed to gain ratio for ducks were reported to be 27.4°C, 27.4°C and 26.0°C respectively (Sun et al 2019). For growing broilers (3-7 weeks) at 25°C, there was no effect on LWG or feed to gain ratio compared with growing at 20°C, but at 30°C all performance measures were depressed (Donkoh 1989).…”

Context. Commercial ducks often experience high temperature in summer and nutritional strategies could help them cope under these conditions. Aims. To assess the effects of water and feed supplements on the growth performance of Pekin ducks exposed to high ambient temperature. Methods. Commercial Pekin ducks were supplemented with betaine in feed, betaine or vitamin C in water or had feed withdrawn for 9 h/day or provided with water alone, during Weeks 5 and 6 of age. Water was supplemented with an 'in house' electrolyte formulation and betaine in Week 6, only. The treatments were applied to two strains, the Cherry Valley (CV) and a commercial line selected from the CV strain for higher breast muscle yield identified as CVP2. On Days 29-41 of age, shed temperature was increased to 30.5°C for 9 h (08:30-17:30) and then returned to 22.7°C for the remainder of the day. Individual liveweights of ducks were measured on Day 28, Day 35 and Day 41 of age. Feed intake and water consumption were measured over Days 14-28, Days 29-35, and Days 36-41. On Day 41, one male and one female from each pen, were weighed, euthanised and the total breast muscle was removed and weighed. Key results. In Week 5, all supplements supported a higher LWG, although this was limited to 4.3-6.3%, with no effects on feed intake or feed to gain ratio. In Week 6, these same supplements provided no benefit and, in fact, vitamin C had a negative effect (−4.7%) on LWG. In Week 6, the electrolyte + betaine improved LWG by 17.1%, with no effects on feed intake or feed to gain ratio. The supplements had no effects on breast muscle weight or yields. The CVP2 selected line had a substantially higher LWG, with nearly all this being due to the 15.8% higher gain seen in males, as LWG of females was similar for both strains. Conclusions. Using electrolytes as a nutritional intervention can help Pekin ducks cope with adverse high temperature and should be evaluated under more extreme high-temperature challenges. Implications. Water electrolyte supplementation can support Pekin duck performance under high-temperature challenge.

“…A duck's thermoneutral zone ranges from 7 to 23 • C (Huang et al, 2008;El-Badry et al, 2009), with the optimal ambient temperature in a commercial housing system suggested to be from 10 to 15 • C (El-Shafaei et al, 2016;Farghly et al, 2017;Sun et al, 2019). Ducks may display signs of heat stress at temperatures as low as 15 • C, through increased panting.…”

Although we have been farming ducks for at least 4,000 years, with some accounts suggesting domestication having begun more than 38,000 years ago, there are still many unknowns for optimizing domestic duck welfare in a commercial setting. Ducks being waterfowl, are semi-aquatic and have unique behavioral needs when compared to other commonly farmed poultry species. Providing ducks with open water which allows for full body immersion so that they may perform their full repertoire of water-related behaviors is important for their health and welfare. However, in a commercial setting this remains challenging due to biosecurity, contamination, health, and management concerns. An important question is therefore how best to provide ducks with a commercially feasible and safe water source in which they can derive maximum welfare and health benefits with no adverse consequences to health or global water resources. This review considers the amount of water provision necessary to satisfy duck's water-related needs to enhance yet not compromise their welfare in a commercial setting based on current knowledge, as well as identifies the outstanding questions for future research to address.
