The invention discloses a feed for different bred silver crucian carp and its preparation method. The main components and corresponding quality parts are as follows: fish meal 10~15%, soybean meal 20~25%, rapeseed meal 20~23%, enzymolysis pig blood powder 10~15%, flour 5~10%, bran 5~10%, soybean oil 3~6%, calcium dihydrogen phosphate 1~3%, compound microecological preparation 1~3%, premix 0.5~2%, and Chinese herbal feed additive 0.5~1%. The preparation methods are as follows: (1) The components of Chinese herbal feed additives are moved into the mixer to stir strongly and mix evenly, then crushed by a crusher, and then sifted by 40-100 meshes, half of the fish meal is added to mix evenly, and the mixture A is obtained; (2) the remaining half of the fish meal and other raw materials are moved to the mixer and fully mixed, then sent to the crusher to crush, the crushing speed is 300-500 r/min. Mixture B is obtained by passing the crushed material through 40-100 mesh screen; (3) Mixture A and mixture B are added to the modulator, then water vapor modulation is introduced, and feed is extruded and extruded, and then dried. The invention can improve the immunity of the allogynous silver crucian carp and reduce the occurrence of the rash virus disease.

一种异育银鲫饲料及其制备方法
本专利技术属于水产养殖
,具体涉及一种异育银鲫饲料及其制备方法。
技术介绍
异育银鲫是以方正银鲫为母本,兴国红鲤为父本经人工受精繁育的子代,该鱼具有食性广、生长快、个体大、抗逆性强,离水存活时间长,可在低温、无水条件下中短途运等优点,深受水产养殖行业的欢迎。目前异育银鲫蛋白质、氨基酸、碳水化合物、脂肪、微量元素等营养需求方面有不少的报道,如CN2015102653223的中国专利申请,生产中也可见配合饲料的相关配方,但是在水产养殖中,为了追求高的效益、集约化、高密度应激的养殖下,病害频繁发生,特别是近年来的孢疹病毒病,鲫鱼的死亡率高达80%以上,尤其对江苏盐城地区,属于高发病,给养殖业带来巨大的经济损失,为防治病原菌,抗生素及抗菌药物得到了大量使用,并造成药物残留、耐药性增强、引起动物免疫力下降,微生态失调,影响了水产养殖业的可持续发展。申请号CN2017111626385的中国专利申请公开了一种防治鲤疱疹病毒Ⅱ型病毒的异育银鲫饲料,主要由以下原料组成:鱼粉、膨化大豆、豆粕、菜粕、细米糠、面粉、豆油、磷酸二氢钙、沸石粉、膨润土、 ...
