Heat stress has to be managed by a combination of management methods.
1) House management
2) Nutritional management
A. HOUSING MANAGEMENT
Maintaining coolness in the poultry house is an important management option. It starts with the planning of house design and also management of the house and the birds after house construction.
Outside of the poultry house, don't allowed tall trees and weeds, it will restrict air flow, while bare ground can reflect heat into the poultry pen. Low cut grass is best as it helps to absorb the sun and heat.
B NUTRITIONAL MANAGEMENT
A ) AVAILABILITY OF COOL DRINKING WATER
Water is the important media for heat loss. About 70-80% of the bird's heat production is dissipated via panting ( evaporating cooling). Adequate water provision is a must as water restriction even for a short period is disastrous for poultry in hot weather. Even though birds drink more water,it's retention in the cells is less because of loss of electrolytes.
B) REDUCTION OF WATER TEMPERATURE
Overhead tanks should not be exposed to constant heat in hot weather. Location of water tanks in shaded area or provision of shade over water tanks keeps water cool. Insulation of water tanks with retaining material reduces the water temperature further. Water pipes must run under ground and any exposed pipes have to be covered to prevent heating of the pipes.
C) WATER TREATMENT
Bacteria grow much more rapidly in the water lines during hot weather. We suggest to do whatever possible to treat your water with water sanitiser that is acidifiers to minimize microorganisms in the gut.
D) FLUSHING THE PIPELINES.
Cooling drinking water by flushing water lines during the afternoon has been shown to increase feed consumption and sustain egg production in heat - stressed layers.
E) ENERGY AND PROTIEN IN FEED.
Fats are excellent sources of energy for poultry to compensate for lower feed intake. Fat is also more digestible ingredient that generates less metabolic heat during digestion compared to starch. Fat has also been shown to slow down feed passage through the gastrointestinal tract, and therefore increases nutrient utilization. Up to 5% or 10% oil can be used.
Reduce the level of protein content in your layer diet during hot weather and you can supplement your Amino acid during this hot weather by using KEPRO AMINO ACIDS as supplements. Heat increment with protein catabolism is more than that of carbohydrates and fat.
F) TIME OF FEEDING
Timing of feeding is an important factor in alleviating heat stress in poultry production. Feed intake and digestion produce *7* % additional heat in body of birds which is maximum 3.5-4hrs after feed intake. It will be better don't offer feed to birds 4hrs before environmental maximum temperature Broilers chickens are appear to be more responsive to the timing of feeding than laying hens. Feed should always be fresh and not be stored for longer period.
G) USE OF VIT E + SEL + C all found in SHARIGROW and Sharivit
Vitamin E + SEL + C wsp is a concentrated water-soluble powder for use in drinking water. Selenium is necessary for growth and fertility and has an interaction with vitamin E that allows each to partially substitute the other. Selenium also has anti-oxidant action. Vitamin E main functions in livestock is to boost anti-oxidant defense,protects cell membrane and to enhances immune function. Vitamin C is essential as a co- enzyme in certain oxidative processes,it is necessary for normal folic acid function and it is also essential for normal wound healing and preserving normal capillary function.
H) USE OF VITAMINS AND ELECTROLYTE
Use of Vitamins and Electrolytes supplements like SHARIGROW and SHARIVIT in drinking water to replenish the loss of sodium, chloride, potassium and bicarbonate in the urine. The electrolyte supplements are best used in anticipation of a rapid rise in environmental temperature.
I. Avoid excessive activity during the hottest part of the day. The hot weather is a great stress on the birds, so avoid bothering and disturbing the birds during periods of peak heat. Adjust work schedules and lightning programs so that routine work is done early in the morning it night. Management practices that require bird handling, such as beak trimming, transfer and vaccination should be done in the early morning hours.
J. AVOID OVERCROWDING OF YOUR FLOCK .
By reducing the number of birds in a poultry house,you are reducing the amount of body heat produced which can be become critical during the hottest part of the day.
