The present invention provides a feed for enhancing meat chicken feeding efficiency and additives thereof. The feed is composed by adding the additives in animal grains, and the components of the additive include polyoxyethylene sorbitan monolaurate as water soluble emulsifying agent and sorbitan oleate, and SiO2 as the carrier, in which the additives can be added into the feed for feeding the meat chicken. By the action of the water soluble emulsifying agent, the final weight for meat chicken may be increased, and the percentage of breast meat for meat chicken may be increased. Thus, the feed additive according to the present invention may improve the animal digestion capability, increase the feed utilization rate, and reduce the cost.本發明為一種提升肉雞飼養效率的飼料及其添加劑,該飼料為於一動物用穀物中添加該添加劑而構成,且該添加劑成分包含作為水溶乳化劑的聚山梨醇酯-80(polyoxyethylene sorbitan monolaurate)與油酸己六酯(Sorbitan oleate),以及作為載體的二氧化矽(SiO2),其所構成的添加劑添加於飼料後可供肉雞食用,以藉由水溶乳化劑的作用,而增加肉雞的末重,同時增加肉雞之胸肉百分比,亦即本發明的飼料添加劑可改善動物消化能力、提高飼料的利用率並降低成本。
