Effects of ambient temperature on growth performance, blood parameter, and fat deposition of geese from 14 to 28 days of age

Effects of citric acid supplementation on growth performance, intestinal morphology and microbiota, and blood parameters of geese from 1 to 28 days of age

“…Alanine amino transferase ( ALT ), aspartate amino transferase ( AST ), total protein ( TP ), albumin ( ALB ), globulin ( GLO ), creatinine ( CRE ), urea, and uric acid ( UA ) in plasma were determined as described by Liu et al. (2022b) .…”

Welfare of ducks, geese and quail on farm

“…Bogenfürst ( 2017 ) found temperatures up to 28°C did not affect egg production negatively. Recent studies with White Sichuan geese aged 14–28 days showed that the upper critical level of ambient temperature for 28‐day‐old body weight and weight gain were around 26°C (Liu et al., 2022a ), while the upper critical levels of ambient temperature from 28 to 49 days of age for weight gain and feed intake were 25.19°C and 23.97°C, respectively (Liu et al., 2022b ). To get rid of the excess heat, Domestic geese may thermoregulate through panting, heat exchange in water via the beak, legs and feet or spreading of the wings.…”

Effects of drinking water temperature in winter on growth performance, water consumption, surface temperature, and intestinal development of geese from 21 to 49 days of age

“…Indeed, the adverse effects of extreme ambient temperatures (cold or hot) on the growth and development of livestock and poultry should not be ignored. In a low-temperature environment, the negative effects of cold stress on animal growth, such as increased feed intake but reduced production performance ( Sahin et al, 2001 ; Alves et al, 2012 ; Shit et al, 2012 ; Olfati et al, 2018 ; Zhou et al, 2021 ), damaged intestinal health ( Liu et al, 2022 ), and increased mortality ( Balog et al, 2003 ), which can cause huge economic losses to the poultry industry. Therefore, it is crucial to find suitable ways to prevent or alleviate this negative effect induced by extreme ambient temperature during the life cycle of poultry.…”
