Heat Stress in Poultry – Solving the Problem:
Simple Tips to Poultry farmers.
- Current production methods often involve large numbers of birds being housed together making them susceptible to heat stress.
- Heat Stress not only causes suffering and death in the birds, but results in reduced or lost production and hence adversely affects the profit from the enterprise.
- House Heat Balance:
Heat is added to the air of a building :
- a) by the body heat production,
- b) heat from electric lights and motors,
- c) sometimes heat from the roof and walls,
- d) and heat from fermentation of the litter or accumulated droppings.
- e) Of these, the dominant source of heat is body heat.
Ways to Combat Heat Stress in Chickens:
- Management methods:
- a) Give cold water below the body temperature of the bird and addition of Vit C in drinking water
- b) Proper feeding time particularly early in the morning or late in afternoon in the tropics and during hot weather
- c) Ensuring good ventilation and air quality within the pen
- d) Proper litter management in the deep litter system
- e) Position sufficient circulation fans correctly.
- f) Insulate the house structure sufficiently to avoid solar heat gain.
- h) Reducing water temperature will ensure lowering body temperature of bird.
- I) in open houses fans, sprinklers ans side curtains should be used to mitigate heat stress.
- We have already discussed about the importance of :
- a) having right phytase in feed .
- b) and the about optimum Dietary Electrolyte Balance.
- c) role of immunomodulators in reducing the stress.
- d) which can help birds overcome fluctuations in health and production that occur during heat stress .
- Immediately advising the farmers to use electrolytes in water to maintain DEB.
- Increase by 10% Vitamins and Minerals in feed.
- Immunomodulators should be used in feed to boost immunity during heat stress which is the need of the hour
- Supply of continuous water is of utmost importance during summer.
- a) First and foremost, make sure your flock has access to clean, cool water at all times! This is crucial!.
- b) Flush water lines and waterers routinely to keep the water fresh and cool.
- In open houses fans, sprinklers and side curtains can be used.
- The use of vitamin C at 150 to 200 gms for ton of feed as an anti-stress agent, is often considered during periods of heat stress.
- In breeding poultry, vitamin C can effectively moderate as:
– warm temperature declines in egg production.
– and eggshell quality in laying hens,
– and sperm production in breeder males.
- There is a strong link between heat stress and intestinal inflammation with far-reaching consequences for intestinal barrier function.
- Probiotics and prebiotics during summer and
- Enzymes in feed during heat stress will:
- a) improve bird’s health and optimise their performance by
- b) positively contribute to microbiome modulation, leading to optimum gut health.
