“…Shenhe et al [ 42 ] also examined the RR in the Mediterranean breed (MB) and a crossbreed (CB, Nili-ravi × Murrah) during the summer and observed that the MB is less tolerant to HS than the CB (76.84 ± 4.31 breaths/min vs. 60.82 ± 5.45 breaths/min, respectively). Wang et al [ 46 ] found similar values for RR during the HS period but also a high RR during the non-HS period. The respiration rate peak, shown as a panting mechanism, corresponds to the incapacity of the buffalo to dissipate heat during the HS period.…”

Increases in temperature and the greater incidence of extreme events are the consequences of the climate change that is taking place on planet Earth. High temperatures create severe discomfort to animal farms as they are unable to efficiently dissipate their body heat, and for this, they implement mechanisms to reduce the production of endogenous heat (reducing feed intake and production). In tropical and subtropical countries, where buffalo breeding is more widespread, there are strong negative consequences of heat stress (HS) on the production and quality of milk, reproduction, and health. The increase in ambient temperature is also affecting temperate countries in which buffalo farms are starting to highlight problems due to HS. To counteract HS, it is possible to improve buffalo thermotolerance by using a genetic approach, but even if it is essential, it is a long process. Two other mitigation approaches are nutritional strategies, such as the use of vitamins, minerals, and antioxidants and cooling strategies such as shade, fans, sprinklers, and pools. Among the cooling systems that have been evaluated, wallowing or a combination of fans and sprinklers, when wallowing is not available, are good strategies, even if wallowing was the best because it improved the production and reproduction performance and the level of general well-being of the animals.

“…All of the references [ 27 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ] agree that there was an increase in RR with the increase in THI. This result could be due to the increase in oxygen demand from the tissues under stressful conditions to try to maintain homeothermy by dissipating heat.…”

“…Among the microorganisms (archaea, fungi, protozoa and bacteria) in the rumen of the buffalo under heat stress, the most changes were seen in bacteria. While heat stress did not have a significant effect on the alpha diversity of rumen bacteria, visible changes in the β-diversity of the bacterial community were detected (Wang et al, 2022).…”

This article has been prepared to examine the effects of heat stress on livestock nutrition, yield and product quality, and to reveal strategies for adaptation and mitigation of climate change. Global climate change is primarily caused by greenhouse gas emissions, which result in warming of the atmosphere. Therefore, soil, air, water pollution and reductions in biodiversity may occur. At the same time, climate change can directly and indirectly affect livestock and animal nutrition. Heat stress results from inability to dissipate enough heat to maintain homeothermy of the animals. High ambient temperature, relative humidity and radiant energy compromise ability to dissipate heat of the animals. Ruminants, pigs and poultry are susceptible to heat stress due to their species-specific characteristics such as their metabolic rate and growth, high yield levels, rumen fermentation, sweating disorder and skin insulation. The indirect effects of climate change on livestock are changes in crop and forage production and quality, decrease in pasture/rangeland quality as a result of decrease in biodiversity and decrease in water availability. The direct effects are on the feed and water consumption, growth, milk, meat, egg, wool/hair and honey yield and product quality of the animals. These effects are primarily the result of a combination of temperature and increase in atmospheric carbon dioxide concentration, variation in precipitation, and relative humidity. Heat stress can cause significant losses in animal production, some of these may be immediate and some may be delayed. Animals under heat stress can decrease feed consumption to reduce metabolic heat. The decrease in feed consumption may cause a decrease in the growth rate of animals, decrease in milk, meat, egg, wool/hair yield and quality. The rations of animals can be manipulated to mitigate the negative effects of climate change.

“…Among the above formulae, THI 1 , THI 3 , and THI 6 are used to monitor discomfort from temperature and relative humidity in humans while THI 2 and THI 7 are used to investigate heat stress effects for cattle exposed in climatic chambers. Only THI 5 is used to determine the level of heat stress in dairy cattle reared outdoor (Bohmanova et al, 2007) with T db and RH representing dry bulb temperature ( o C), and relative humidity (%), respectively (Wang et al, 2022). Formulae used to calculate other environmental parameters (THI, adjusted temperature humidity index (THI), heat load index (HLI), equivalent temperature index (ETI), environment stress index (ESI), comprehensive climate index (CCI), relative humidity, wind speed, solar radiation and predicted globe temperature) are presented in Table 2, as reported in the study by Hammami et al (2013).…”

“…It has been developed as a climate index to determine and reduce losses associated to heat stress (Bohmanova et al, 2007). In dairy cattle, THI that exceeds a particular threshold for cattle, often leads to significant declines in feed intake, extreme water consumption, alteration in milk yield traits, and lowered fertility (Gálik et al, 2021;Wang et al, 2022).…”

Genes and models for estimating genetic parameters for heat tolerance in dairy cattle

Dairy cattle are highly susceptible to heat stress. Heat stress causes a decline in milk yield, reduced dry matter intake, reduced fertility rates, and alteration of physiological traits (e.g., respiration rate, rectal temperature, heart rates, pulse rates, panting score, sweating rates, and drooling score) and other biomarkers (oxidative heat stress biomarkers and stress response genes). Considering the significant effect of global warming on dairy cattle farming, coupled with the aim to reduce income losses of dairy cattle farmers and improve production under hot environment, there is a need to develop heat tolerant dairy cattle that can grow, reproduce and produce milk reasonably under the changing global climate and increasing temperature. The identification of heat tolerant dairy cattle is an alternative strategy for breeding thermotolerant dairy cattle for changing climatic conditions. This review synthesizes information pertaining to quantitative genetic models that have been applied to estimate genetic parameters for heat tolerance and relationship between measures of heat tolerance and production and reproductive performance traits in dairy cattle. Moreover, the review identified the genes that have been shown to influence heat tolerance in dairy cattle and evaluated the possibility of using them in genomic selection programmes. Combining genomics information with environmental, physiological, and production parameters information is a crucial strategy to understand the mechanisms of heat tolerance while breeding heat tolerant dairy cattle adapted to future climatic conditions. Thus, selection for thermotolerant dairy cattle is feasible.
