反芻牛羊動(dòng)物飼喂一般都以蛋白質(zhì)為主,膨化尿素可以為反芻牛羊等動(dòng)物飼料提供生長(zhǎng)所需的蛋白質(zhì)。一般牛養(yǎng)殖的配方中玉米占60%,豆粕占20%,麥麩占14%,食鹽0.8%,一般我們認(rèn)知的豆粕,菜粕,全脂大豆等蛋白原料是牛羊主要飼料牧草類食物,大部分地區(qū),大多的草,能夠利用的并不多,尤其是較大型的養(yǎng)殖場(chǎng),所用的牧草較多,但是在每個(gè)季節(jié)都有差異,一般都要根據(jù)季節(jié)得變化來調(diào)整飼料的飼喂方式。尤其是冬春季,牛的飼草質(zhì)量較低,在飼草上加喂適量膨化尿素,更好的吸收飼料中的營(yíng)養(yǎng),可促進(jìn)反芻牛羊增肥和健康,提高飼喂效果!
在當(dāng)前蛋白質(zhì)飼料缺乏并價(jià)格高昂的情況下,如何促生長(zhǎng),降低成本,提高養(yǎng)殖經(jīng)濟(jì)效益是擺在養(yǎng)殖飼養(yǎng)方面的重要問題。而新型非蛋白氮膨化尿素的誕生,無疑是解決了這種難題,它既是一種成本低廉的反芻動(dòng)物蛋白質(zhì)代用飼料,科學(xué)飼喂的話可以解決蛋白質(zhì)飼料不足,節(jié)約蛋白質(zhì)飼料資源,降低飼料成本和提高養(yǎng)殖經(jīng)濟(jì)效益。
飼料級(jí)膨化尿素與普通的工業(yè)尿素不同,膨化尿素粗蛋白≥200%,含氮量≥32%、水分≤10%、鉛(mg/kg)≤30、總砷(mg/kg)≤10,普通尿素含氮量≥46%,在瘤胃中分解速度過快,對(duì)反芻動(dòng)物瘤胃會(huì)有不好的影響,
膨化尿素在反芻動(dòng)物上要科學(xué)飼養(yǎng),在飼喂過程中也要注意幾個(gè)事項(xiàng):
一、膨化尿素配合一定的精料或容易消化的碳水化合物(如 糖蜜、淀粉等)作為微生物的營(yíng)養(yǎng)源增加適口性,碳水化合物是瘤胃微生物利用氮合成蛋白是不可缺少的能源,效果更好,以利于增加牛的采食量。
二、膨化尿素溶于清水或糖漿中,灑在新鮮青綠牧草上,讓牛舔食。會(huì)有更多的過瘤胃蛋白,蛋白質(zhì)在真胃和小腸消化吸收,利用效率更好。(不可以直接讓牛飲用)
三、 小于六個(gè)月的幼齡反芻動(dòng)物也不可以使用,因?yàn)榱鑫高€沒有發(fā)育好,里面沒有微生物菌群,不能自身合成菌體蛋白讓其吸收。
Ruminant cattle and sheep animal feeding is generally based on protein, and puffed
urea can provide the protein needed for growth for animal feed such as ruminants and
sheep. General cattle breeding formula in corn accounted for 60%, soybean meal
accounted for 20%, wheat bran accounted for 14%, salt 0.8%, generally we recognize
soybean
meal, rape meal, full-fat soybean and other protein raw materials are the main feed forage grass food for cattle and sheep, most of the area, most of the grass, can not be used much, especially
larger farms, the use of more pasture, but in each season there are differences,
generally
according to seasonal changes to adjust the feed feeding method. Especially in winter
and spring, the quality of cattle forage is low, and feeding an appropriate amount of
puffed urea on the forage to better absorb the nutrients in the feed can promote the
fattening and health of ruminant cattle and sheep, and improve the feeding effect!
In the current situation of protein feed shortage and high price, how to promote
growth, reduce costs, and improve the economic benefits of breeding is an important issue in breeding and feeding. The birth of a new type of
non-protein azophosed urea undoubtedly solves this problem, it is not only
a lowcost ruminant protein substitute feed, scientific feeding can solve the protein feed shortage, save protein feed resources, reduce feed costs and improve the economic benefits of breeding.
Feedgrade puffed urea is different from ordinary industrial urea, puffed urea crude protein ≥ 200%, nitrogen content ≥ 32%, water ≤ 10%, lead (mg/kg) ≤30, total arsenic (mg/kg) ≤ 10, ordinary urea nitrogen content ≥ 46%, decomposition in the rumen is too fast, there will be a bad impact on the rumen of ruminant rumen,
Puffed urea should be scientifically raised on ruminants, and several things should be
paid attention to during feeding:
First, puffed urea with a certain concentrate or easy to digest carbohydrates (such as molasses, starch, etc.) as a source of nutrition for microorganisms to increase palatability, carbohydrates are rumen microorganisms using nitrogen synthesis protein is an
indispensable energy source, the effect is better, in order to facilitate the increase of
cattle feed intake.
Second, the puffed urea is dissolved in water or syrup, sprinkled on the fresh green
grass, and let the cow lick and eat. There will be more rumen proteins, which are
digested and absorbed in the true stomach and small intestine, and are used more
efficiently. (You can't drink it directly from the cows)
Young ruminants less than six months old can not be used, because the rumen has not yet developed well, there is no microbial flora in it, and it cannot synthesize the
bacterial proteins by itself for absorption.
