【摘要】：近年來,植物性飼料添加劑得到了廣泛的研究和試用,最初應(yīng)用是因?yàn)槠涮厥獾臍馕犊梢源龠M(jìn)動(dòng)物唾液和消化液的分泌,提高采食量。后來,研究者發(fā)現(xiàn)植物性飼料添加劑中的化學(xué)活性物質(zhì)可以有利于保證腸道的菌群健康,提高畜禽的抗病能力、促進(jìn)動(dòng)物生長。隨著近年來消費(fèi)者對于食品安全的重視以及肉雞養(yǎng)殖行業(yè)的發(fā)展要求,正確合理地選擇和使用添加劑越發(fā)重要。本課題就植物性飼料添加劑在白羽肉雞飼養(yǎng)中的實(shí)際應(yīng)用進(jìn)行驗(yàn)證,以指導(dǎo)飼料生產(chǎn)中肉雞日糧的合理配制。試驗(yàn)所使用的植物性飼料添加劑(英文名BIOSTRONG#174;510,簡寫為BSG)。主要成分:植物精油(薄荷精油、肉桂精油)、植物苦味物質(zhì)(苦艾草)、辛辣物質(zhì)(辣椒素、大蒜)等。結(jié)果表明,日糧中添加植物性飼料添加劑在一定程度上促進(jìn)了肉雞生產(chǎn)性能,提高了腸道健康和消化吸收能力,提高了肉雞的抗氧化能力,并且提高了收益。本課題還就植物性飼料添加劑在商品蛋雞飼養(yǎng)中的實(shí)際應(yīng)用進(jìn)行了驗(yàn)證,以指導(dǎo)飼料生產(chǎn)中蛋雞日糧的合理配制。結(jié)果表明,在蛋雞日糧中添加BSG對其應(yīng)用前期可通過調(diào)整飼料營養(yǎng)成分大大降低采食量(降低13.2%),減少飼料損耗,節(jié)約飼料成本。但中長期添加BSG在一定程度上會(huì)降低雞蛋哈氏單位、蛋殼厚度、蛋殼硬度、蛋白高度、蛋黃顏色,影響雞蛋品質(zhì),降低雞蛋等級(jí)。這些實(shí)際生產(chǎn)的數(shù)據(jù)為植物性飼料添加劑在肉雞、蛋雞飼養(yǎng)中的合理使用提供了基礎(chǔ)數(shù)據(jù)。
[Abstract]:In recent years, plant feed additives have been extensively studied and tested, initially because their special odors can promote the secretion of animal saliva and digestive fluids and increase feed intake. The researchers found that the chemical active substances in plant feed additives can help to keep the intestinal flora healthy and improve the disease resistance of livestock and poultry. Promote the growth of animals. With the attention of consumers to food safety and the development requirements of broiler breeding industry in recent years, It is more and more important to select and use additives correctly and reasonably. This paper verifies the practical application of plant feed additive in raising white feather broiler. In order to guide the rational preparation of broiler diets in feed production. Plant Feed Additives used in the experiment (BIOSTRONG#174H510, abbreviated as BSGG). Main ingredients: essential Oil of Plant (essential Oil of Menthol, essential Oil of Menthol, essential Oil of Menthol, essential Oil, essential Oil, essential Oil, essential Oil, etc. The results showed that the addition of plant feed additive to the diet promoted the performance of broiler to some extent. It can improve intestinal health, digestion and absorption ability, antioxidant ability and income of broiler. The practical application of plant feed additive in commercial laying hens was verified in this paper. In order to guide the reasonable preparation of laying hens diet in feed production, the results showed that adding BSG to the diet of laying hens in the early stage of application could greatly reduce the feed intake by adjusting the nutritional composition of the feed (reducing 13.2% and reducing the loss of feed). However, adding BSG in the medium and long term will reduce the eggshell thickness, eggshell hardness, egg height, egg yolk color and egg quality. These actual production data provide basic data for the rational use of plant feed additives in broiler and laying hens.
