Qatar has a flat terrain. Most areas are deserts covered with sand and soil. It is slightly higher near the west coast. Qatar has a tropical desert climate, hot and dry, and wet along the coast. The four seasons are not very obvious. The summer from April to October is the longest season of the year. The highest temperature is from July to September, which can reach 45 ℃. Winter is cool and dry. Rainfall occurs in winter, and the lowest temperature is 7℃. The average annual precipitation is only 75.2 mm.
In a hot and dry climate like Qatar, laying hens should pay more attention to breeding management, because higher temperatures, coupled with chicken body temperature, will lead to a reduction in feed intake, thus reducing egg production and profit.
In hot-dried Qatar, we must strengthen chicken coop ventilation, micro-environmental management, adequate water, management and nutrition.
(1) Improve ventilation conditions and ensure sufficient water
The house should have a good environment and sufficient fresh air. Therefore, ventilation in the house is very important. The ventilation of the chicken house can take away the heat in the house (when the outdoor temperature is lower than the indoor temperature), if the outdoor temperature is higher than the inside of the chicken house, increasing the wet curtain can allow the flowing air to take away the temperature in the chicken house. A comfortable temperature can let the eggs Chicken egg production has increased and farmers have more income.
Chicken farmers will have to prepare carefully to protect chickens from heat waves and provide enough fresh water, and prepare for high temperature alerts. Farmers can use conical ventilation fans to increase micro-environment control to manage chicken coops, wet curtains, roof fans, and sand / dust-proof air intakes.
(2) Strengthening environmental management
Qatar chicken houses can be built on well-ventilated open land and equipped with lawns or trees. Try not to use concrete and masonry floors around the chicken houses, because the cement and masonry floors will absorb heat more quickly, causing chicken house temperature Raise, and plant more flowers and trees around the house to maintain a good air flow.
(3) improve management
In Qatar, a tropical desert climate, high temperature control is the focus and foundation of breeding management. Controlling high temperature can prevent flocks from heat stress. If flocks have heat stress, take measures in time, take spray cooling, increase water consumption, The feeding frequency and the feeding amount, and the luminous time are increased. At the highest temperatures of the day, stop feeding and try to reduce chicken activity so that the chicken can be quiet.
(4) Nutritional supplements
At high and high temperatures, the feed intake of most laying hens will decrease and egg production will be reduced. Therefore, it is important to improve nutrition and maintain calorie balance in the body. Increase the protein-to-energy ratio in feed, adding 10 to 20 kg of fat per ton of feed,
Provides plant protein and increases methionine content (58%). At the same time, adjust the electrolyte balance and add more vitamin C supplements, bicarbonate and sodium chloride, and vitamin E (150 mg per ton) to the feed.
