Abstract :

Climate change can securely affect the productivity and economic viability of the Livestock Production Systems. High ambient temperature affects particularly high yielding, low disease resistant and low heat tolerant crossbred population than the indigenous livestock. Heat stress induced by change in climate also affects the reproductive performance of dairy animals compared to meat producing animals. The negative impact of temperature rise on total milk production in India has been estimated to be 1.6 million tonnes by 2020 and more than 15 million tonnes by 2050. An increase in the global temperature of only 1.5 to 2.5o C may lead to extinction of approximately 20-30% of livestock and animal species in the world. To mitigate the adverse effects of extreme weather events, technologies suitable to local conditions and modifications in housing of animals, managemental and feeding practices need to be designed for future. Environmental modifications aiming at microclimate of the animal to help alleviate heat stress problems are structural orientation, ventilation, use of cooling system along with shade is the best. An integrated approach was made in the model project on the â�?�?Environmentally Controlled Housingâ�?. It was designed for Dairying cattle at Dairy Experimental Station, College of Veterinary Science, Tirupati under Sri Venkateswara Veterinary University by giving due consideration to orientation of shed, roof projection and microenvironment of the animal by providing cooling system besides comfort to the animal and reducing the labor costs involve in feeding and management. The micro environment around the animal is modified by to increase the heat dissipation and cooling the air around the animal to reduce the heat load and stress on the animal.
