This combined with the animal’s increased rate of bodily heat generation causes hyperthermia. Heat stress causes a variety of alterations that might result in decreased breedingeffectiveness, decreased productivity, and in severe situations, even death. Every year, heat stress causes major losses in milk production in India, resulting in enormous financial losses. In addition to its negative effects on oestrus expression and conception rate, heat stress also lengthens the dry period and increases the length of service.Cattle that are crossbred or exotic are more susceptible to heat stress, even though native breeds are more thermotolerant. Due to their darker skin, which absorbs more sun radiation, and their smaller sweat gland count (one-sixth that of cattle), buffaloes are more vulnerable to this. This reduces their ability to dissipate heat by evaporative heat loss.
Summer stress sign
Fast and feeble heart rate Breathing quickly but superficially Abnormal vital parameters include elevated heart rate, breathing rate, rectal temperature Peculiar salivation pattern Unconsciousness Body temperature of aanimal suffering from heat stroke might reach a high of 106 to 108°F.
Management of summer stress
Make sure the animals are housed in shade. Trees are the best natural shade source. A thatched roof with a minimum height of nine feet should be supplied in the absence of shade trees.
A cooler atmosphere can be achieved by thatching the roof with materials such as paddy straw, painting the roof white or installing fake ceiling insulation.
Build wind-blocking structures out of thatched walls or damp gunny bags or linen.
In a covered shed, make sure each cow has a ventilator measuring three by one foot.
The best solution in these enclosures is a heavy-duty fan to facilitate ventilation
Misting/Fogging of water on animals.
Another way to alleviate heat discomfort in animals is to physically spray or sprinkle water on their bodies.
Wallowing in the water pond is the most efficient method for buffalo to recover from heat stress.
Make sure animals have access to enough drinking water throughout the day, preferably in a shaded area.
It is recommended to practise feeding in the early morning, evening and night.
To avoid the intense heat, prefer grazing in the early morning and late evening hours.
Ration density can be raised to deliver the same nutrients while consuming less dry matter. Dietary heat increase is smaller in low-fiber and high-fermentable-carb diets than in high-fiber diets.
To satisfy the increased demand for minerals during hot weather, make careful to ensure enhanced supplementation of minerals. It is best to use a mineral mixture that is high in potassium.
Conclusion
Summer stress in dairy cattle is a pressing concern with significant economic and production-related consequences. By implementing effective management strategies and prioritizing cow comfort, dairy farmers can navigate the summer months while ensuring the well-being of their herd and maintaining milk production.
