新玉米的特點：

1. 新玉米下來，需要一個月的后熟期，即淀粉轉化過程。

　　如果轉化未完成，則能量不足，雞群表現為減料、消瘦，雞群腸道病加重。

2. 新玉米水分大，易發霉。

　　霉菌的衍生物霉菌毒素會破壞機體的免疫系統，大大降低雞體的抗病能力.

3. 新玉米的營養價值低。

有自作聰明的農戶，因新玉米的營養價值低而添加油脂，結果適得其反，更會加重腹瀉，既浪費錢財，又損害雞群健康。

新玉米新小麥，科學分析發現，都要經過兩次成熟，才能將產能發揮到極致，剛下市的玉米小麥，含有一種不易被動物吸收的大分子多糖，粘性大，不吸收，吃的稍多，就會引起消化不良，腹瀉等不適。有人用鮮嫩的玉米煮熟或燒熟，多吃幾口就有反應。新小麥加工成面粉，吃起來粘性大，口感澀，影響消化。

只有放置一個月以上，讓糧食第二次成熟，使大分子多糖轉化成容易吸收的淀粉，能量才能被很好利用，這個過程叫淀粉化過程。

新玉米的危害

1. 水份含量大而不穩定。

2. 新玉米成熟滯后性易引起拉稀現象和過料，這個危害，陳玉米就沒有。

3. 新玉米中有毒素的危害、霉菌的危害要大于陳玉米，需注意霉菌和霉菌毒素危害的區別。

霉菌毒素對不同雞群的影響：

蛋雞：

1、病雞采食量大大減少，精神萎靡并因厭食而體重下降：

2、產蛋量迅速下降，產畸形蛋，白殼蛋、薄殼蛋、軟皮蛋增多；

3、腸道病增多，出現經常性拉稀，而且拉稀癥狀嚴重，排黑色粘性糞便，采食減少，死亡率增加；

4、雞冠腫大、發紅、出現“假公雞”現象。

肉雞

1、初期癥狀表現為精神不振，有呼吸道癥狀，主要表現呼吸困難，呼吸頻率加快，有羅音，有的甩頭，流淚、眼水腫、大群內可聽見有呼嚕聲；

2、發病中后期呼吸道癥狀基本消失，病雞精神沉郁，畏寒，閉眼呆立，給予驚嚇刺激后迅速躲開，縮頭垂尾，翅膀下垂或羽毛蓬亂不整，采食和飲水急劇減少，出現死亡現象；

3、病雞眼結膜渾濁不清，有的出現失明而影響采食；

4、病雞拉稀嚴重，飼料轉化率降低，排白色，白綠色、黃綠色稀糞，糞便呈油性“魚腸”樣或爛胡蘿卜樣，有的病雞少數排出綠色糞便，糞便中有未消化的飼料和粘液，沾污肛門周圍羽毛；

5、病雞素囊內有積液，頸部膨大。

6、雞群生產水平下降，少量病雞發生跛行，最終衰竭死亡。

解決的辦法：

玉米放置一個月以后再用，也可以新、陳玉米按一定比例摻合，逐漸替換，待一個月以后完全替換。更換飼料期間飼料中需添加和美嘉“霉毒痢凈”，具有抑霉解毒、物理吸附、化學結合、增強免疫力之功效。

The characteristics of the new corn:

1. The new corn, need a month after ripening period, namely starch conversion process.

If the conversion of unfinished, the energy shortage, chickens characterized by reduction of material, angular, chickens intestinal disease.

2. New corn moisture, easy to moldy.

The derivatives of mold mycotoxin can destroy the body's immune system, reduce the resistance of the chicken body.

3. The nutritional value of new corn is low.

A smart Aleck farmers, because of the low nutritional value of new corn add grease, backfired and more can aggravate diarrhea, waste money already, and impair the health of the crowd.

New corn wheat, scientific analysis, found that it takes two mature, to get to the maximum capacity, just the delisting of maize and wheat, contains a kind of not easy to be absorbed by animal macromolecular polysaccharide, big viscosity, do not absorb, eat a bit more, it will cause indigestion, diarrhea and other discomfort. People with fresh corn boiled or cooked, eat a few mouth there is reaction. New wheat into flour, eat big viscosity, taste astringent, affect the digestion.

Only placed one month or more, make food for the second time to mature, make the macromolecular polysaccharide into easy to absorb starch, energy can be good use, this process is called starch process.

The dangers of new corn

1. The water content and unstable.

2. New maize mature hysteresis easy cause diarrhea phenomenon and the material, the harm, Chen corn, there is no.

3. The new corn with toxins, mould of the hazards than Chen corn, attention should be given to the difference of the mold and the mold toxin harm.

The influence of mycotoxin on different crowd:

Layers:

1, the sick chicken feed intake reduce greatly, depression and for anorexia and weight loss:

2, egg production fell rapidly, eggs with deformity, soft, thin shell egg, preserved egg white shell egg increase;

3, intestinal disease increased, frequent diarrhea, and severe diarrhea symptoms, black sticky waste, to reduce food intake increased mortality;

4, comb swelling, redness, appear "fake rooster" phenomenon.

chicken

1, the early symptoms are depressed, have respiratory symptoms, mainly difficulty breathing, breathing is accelerated, rale, some head, tears, eye edema, can be heard within a large group of snoring sound;

2, in mid and late onset of respiratory symptoms disappeared basically, depressed of ill chicken spirit, chills, close your eyes stay, to frighten away immediately after the stimulation of its tail, wings prolapse or feathers tumbled not whole, feed intake and water decreased dramatically, death occurs;

3, disease corns conjunctival turbidity is not clear, some feed in blindness and influence,

4, severe disease chicken diarrhea, reduce feed conversion, white, white and green, yellow-green, loose stool, stools oily or rotten carrots "lift fire" samples, some sick chicken minority discharge green manure, waste of undigested feed and mucus, contamination around the anus feathers;

Five, sick chicken vegetable capsule has effusion, neck).

6, chickens production levels drop, a few sick chicken claudication, final failure death.

The solution:

Use corn placed one month later, also can be new, Chen corn mixed according to certain proportion, gradually replaced, to completely replace a month later. Replace the need to add in feed during the feed and jia "mildew toxic dysentery net", has a "mould suppression detoxification, the effect of physical adsorption, chemical combination, enhance immunity.
