Biochemical and Physiological Changes during Thermal Stress in Bovines (2013, background): “In terms of adaptation measures, it is generally faster to improve welfare, production and reproduction performances of animals by altering their micro-environment [12,13].”
Effects of heat stress and plane of nutrition on lactating Holstein cows: I. Production, metabolism, and aspects of circulating somatotropin. (2009, background): “2 Corresponding author: baumgard@ag.arizona.edu tion in milk production, it is generally accepted that reduced nutrient intake is primarily responsible for the diminished milk synthesis (see reviews by Fuquay, 1981; Beede and Collier, 1986; West, 2003).”
Metabolic and hormonal acclimation to heat stress in domesticated ruminants. (2010, background): “Reduced feed intake caused by heat stress has traditionally been assumed to be primarily responsible for the decrease in milk yield (Collier et al., 1982a; West, 2003).”
Climate Change, Heat Stress, and U.S. Dairy Production (2014, positive): “In dairy cows, higher temperatures lower milk output and reduce the percentages of fat, solids, lactose, and protein in milk (Kadzere et al., 2002; St-Pierre et al., 2003; West, 2003).”
Is the temperature-humidity index the best indicator of heat stress in lactating dairy cows in a subtropical environment? (2009, background): “Heat stress has adverse effects on milk production and reproduction of dairy cattle (Kazdere et al., 2002; West, 2003; Hansen, 2007).”
Adaptation to hot climate and strategies to alleviate heat stress in livestock production. (2012, background): “Shade is effective in protecting cows from solar radiation, but does not alter the air temperature or RH around the cows to maximize sensible routes of heat loss (Armstrong, 1994; West, 2003).”
Dairy cows prefer shade that offers greater protection against solar radiation in summer: Shade use, behaviour, and body temperature (2009, background): “005 by environmental factors such as air temperature, relative humidity, wind speed and solar radiation, elicits behavioural and physiological responses, including increased body temperature and respiration rate, and reduced activity and feed intake (Hahn, 1999; Ominski et al., 2002; West, 2003; Tap”
Temperature-humidity indices as indicators of milk production losses due to heat stress. (2007, background): “…and relative humidity (Igono et al., 1985; Igono and Johnson, 1990; Ravagnolo and Misztal, 2000; Bouraoui et al., 2002; St-Pierre et al., 1947 2003; West, 2003; Correa-Calderon et al., 2004) because data on the amount of thermal radiation received by the animal, wind speed, and rainfall are not…”
Different levels of response to heat stress in dairy goats (2014, background): “At THI =72–75, milk production and fertility are negatively affected in dairy cows and economic losses are expected as reviewed by West (2003). A high THI also reduces the feed intake of animals, causing a negative energy balance and BW losses.”
Contrasting responses of urban and rural surface energy budgets to heat waves explain synergies between urban heat islands and heat waves (2015, background): “In addition to human health, HWs also have significant impacts on ecosystem productivity (Ciais et al 2005), animal production (West 2003), labor capacity (Dunne et al 2013), and energy/water consumptions (Sailor and Pavlova 2003).”
