在高温环境下鸭会张口呼吸以增加体内热量分发以及热应激带来的影响,鸭采食量会随温度的升高而降低,因而应依据实践状况停止恰当的调整,以保证鸭摄入正常所需的营养。
In high temperature environment, ducks open their mouths to breathe in order to increase the heat distribution and the influence of heat stress. The feeding intake of ducks will decrease with the increase of temperature. Therefore, appropriate adjustment should be stopped according to the actual situation to ensure that ducks take the normal nutrients.
1、维生素及矿物质的添加:夏季天气酷热,鸭体排泄的钠和钾增加,由于喘息的频率增加,血浆中的二氧化碳浓度降落,有可能呈现呼吸性碱中毒,因而,在日粮或饮水中,补加额外的钠和钾,以及在饮水中补加碳酸盐均有利于维持电解质均衡,在饲料中添加0.1%---0.5%碳酸氢钠有效减轻热应激。高温时饲料中的营养物质易被氧化,此外热应激也易形成鸭生理慌张,降低对维生素C的合成才能,增加了对维生素营养物质的需求,因而应恰当增加电解多维的运用量,在每千克饲料中添加100-200毫克维生素C,有利于减轻热应激对鸭机体的不利影响,同时可使其他营养物质免遭氧化。
1. Addition of vitamins and minerals: In hot summer, the excretion of sodium and potassium from ducks increases. As the frequency of wheezing increases and the concentration of carbon dioxide in plasma decreases, respiratory alkalosis may occur. Therefore, supplementation of additional sodium and potassium in diet or drinking water, and supplementation of carbonate in drinking water are conducive to maintaining electrolyte balance. Addition of 0.1%-0.1% in feed is beneficial. - 0.5% sodium bicarbonate can effectively alleviate heat stress. At high temperature, nutrients in feed are easily oxidized. In addition, heat stress can easily cause duck physiological panic, reduce the ability to synthesize vitamin C and increase the demand for vitamin nutrients. Therefore, it is necessary to increase the amount of multidimensional electrolysis and add 100-200 mg of vitamin C in every kg of feed, which is conducive to alleviating the adverse effects of heat stress on duck's body, and at the same time can make other kinds of food available. Nutrients are protected from oxidation.

2、调整饲喂时间:白昼酷热时减少饲喂或不饲喂,而在晚上或清晨饲喂,并恰当驱逐鸭群增加采食量,每次喂料时不要加过多的饲料,料要坚持新颖,避免霉变,料筒要每天清空一次,不能累加,高温、高湿的天气,再加上喷水降温,饲料很容易呈现结块蜕变,影响适口性,形成鸭厌食,严重时发作中毒。中午时可恰当添加青菜或西瓜皮以缓解热应激。

2. Adjust feeding time: reduce feeding or not feeding in hot day, but feed in the evening or early morning, and properly expel ducks to increase feed intake. Do not add too much feed when feeding. Feed should be novel and avoid mildew. Feed cylinder should be empty once a day, not cumulative. High temperature and humid weather, coupled with spraying water to cool down, feed is easy to cake and metamorphose. The sound is palatable, forming anorexia in ducks and poisoning in severe cases. At noon, vegetables or watermelon peels should be added properly to alleviate heat stress.
3、供应新颖饲料:夏季高温高湿饲料容易霉变,既形成营养成分的流失又容易形成霉变发作霉菌毒素中毒,因而应增强饲料的保管措施,防晒防潮,备料时应恰当减少备料量;以5-7天料量为好,以保证饲料的新颖。
3. Supply of new feedstuffs: In summer, high temperature and humidity feedstuffs are easy to mildew, which results in loss of nutrients and mildew and mycotoxin poisoning. Therefore, it is necessary to strengthen the measures of feedstuff preservation, protect against sunshine and moisture, and reduce the amount of material reserved appropriately; 5-7 days of feedstuff is the best to ensure the novelty of feedstuffs.
