Fish silage was prepared from some fish species of the shrimp by-catch caught in Golfo Triste, Carabobo, Venezuela. Fish were ground until a particle size that would guarantee the liquefaction process was achieved. The process was accelerated by the incorporation of a 3.5% w/w acid mixture, formed by diluted sulfuric acid (1:3) and concentrated formic acid, in a proportion of 1:4. The silage process occurred spontaneously at room temperature during 17 days. Chemical, physical and microbiological tests were conducted in order to characterize both the raw material and the final product. The raw material used had adequate levels of freshness, so that it was suitable for use, thus producing a first-grade silage. A first biological evaluation was carried out in rats in order to estimate the protein quality of the silage by means of certain biological parameters such as PER, NPR and apparent digestibility percentage of the protein. The results of the first experimental period demonstrated that the fish silage protein was of optimal quality, since the biological response in rats was similar to that of the control group fed the casein diet.
鱼青贮饲料由在委内瑞拉卡拉沃沃州的特里斯特湾捕获的虾类兼捕渔获物中的一些鱼类制成。将鱼研磨，直至达到能确保液化过程的颗粒大小。通过加入由稀硫酸（1:3）和浓甲酸按1:4比例组成的3.5%（w/w）酸混合物来加速该过程。青贮过程在室温下自发进行17天。进行了化学、物理和微生物测试，以表征原料和最终产品。所使用的原料具有足够的新鲜度，因此适合使用，从而生产出一级青贮饲料。在大鼠中进行了首次生物学评估，以便通过某些生物学参数（如蛋白质效率比值、净蛋白质比值和蛋白质表观消化率）来估计青贮饲料的蛋白质质量。第一个实验期的结果表明，鱼青贮饲料蛋白质质量最佳，因为大鼠的生物学反应与喂食酪蛋白日粮的对照组相似。
