The invention relates to a preparation method for an ostrich fodder. The ostrich fodde comprises main components in percentage by weight: 12 to 16 percent of erythroculter powder, 10 to 12 percent of millet flour, 8 to 10 percent of soybean straw powder, 4 to 6 percent of barley flour, 2 to 4 percent of grass seed powder, 8 to 12 percent of wheat flour, 4 to 8 percent of soy protein powder, 8 to12 of corn flour, 8 to 10 percent of rice flour, 2 to 4 percent of calcium powder, 2 to 4 percent of cod-liver oil, 1 to 3 percent of salt, 1 to 3 percent of Danshen Roots, 2 to 4 percent of Indian Buead, 1 to 3 percent of Amur Corktree Bark, 2 to 4 percent of elecampane, 1 to 3 percent of Unibract Fritillary Bulb, and 2 to 4 percent of ginkgo seedse. The preparation method comprises the following steps: taking the powder according to the proportion, putting all the powder into a compound stirrer for stirring; taking out the mixture, and putting the mixture into a ring mode crusher for crushing; then taking out the mixture, putting the mixture into a dryer for drying; taking out the mixture, and putting the mixture into a ring mode bulking machine for bulking; taking out the mixture, transferring the mixture into a ring mode hard granulation machine, and generating the sediment hard granule fodder; then screening the fodder by a screen of 80 mesh; and ensuring the weight of each granule is 0.2 g, sealing and packing the fodder according to the required weight.

The present invention discloses an ostrich sinew and bone medicated liquor, said medicated liquor contains alcohol, sugar, solids and ostrich sinew and bone, and its preparation includes the following steps: soaking the ostrich sinew and bone and Chinese medicinal materials in alcohol, the filtering and blending so as to obtain the invented product which richly contains gamma-globulin, mucopolysaccharide and several track elements and has the good action of resisting senility and activating immunity of human body.

The invention discloses a preparation method of a catalyst for preparing biodiesel. The preparation method comprises the following steps: cleaning an ostrich egg eggshell by utilizing distilled water to remove impurities on the surface of the eggshell, and drying the eggshell for 12 to 20 hours at the temperature of 90 to 110 DEG C; crushing the eggshell, and filtering the crushed eggshell by utilizing a 160-mesh to 180-mesh sieve; and placing the filtered eggshell in a muffle furnace, roasting the eggshell for 2h at the temperature of 800 to 1000 DEG C under the condition of introducing nitrogen, so as to obtain white solid powder of the catalyst for preparing the biodiesel, and vacuum drying and storing the prepared catalyst. The preparation method has the advantages: (1) the raw material for preparing the catalyst is low in price, wide in source and good in regeneration effect; (2) the catalyst prepared in the method is relatively high in catalytic activity, and experiments show that the yield of the biodiesel can reach more than 90 percent; (3) the catalyst is recyclable, and when the catalyst is reused for six times, the yield of the biodiesel still can reach more than 80 percent.

The invention discloses a bionic tendon-bone synergetic rigid-flexible coupling sand-crossing mechanical foot which comprises a foot body mechanism, a buffering and damping mechanism, a flexible passive control mechanism, a main toe and an auxiliary toe. The bionic tendon-bone synergetic rigid-flexible coupling sand-crossing mechanical foot takes examples from biological structure and assembling of the foot tendon-bone of an ostrich and the tendon-bone synergetic working principle, the buffering and damping mechanism can decrease the speed when the foot falls on the ground, and the impact on the ground is reduced; and under the effect of a flexible passive control system, the main toe and the auxiliary toe are open when falling on the ground, a torsion spring is compressed to store energy,the main toe and the auxiliary toe are closed when leaving the ground, and the torsion spring is bounced off to release the energy. According to the bionic tendon-bone synergetic rigid-flexible coupling sand-crossing mechanical foot, opening and closing of the two toes are controlled in a passive mode, through the movement of hitting the ground of the main tone, the number of power sources is decreased, the energy loss is reduced, the supporting area of the foot and the ground is increased, and the stability during travelling of a foot robot is improved; and the buffering and damping mechanism and the flexible passive control mechanism are combined through a lever, and the impact of the ground to the foot is effectively reduced.

Disclosed is an antibody produced using an ostrich. Also disclosed is a method for producing the antibody. By using an ostrich, it becomes possible to produce antibodies (particularly antibodies for medical use), which have been hardly produced by using the mammals such as the mouse and the rat, homogeneously in a single body, in large quantities and in a simple manner. The method can overcome a disadvantage of lot-to-lot variation which may occur in the production of polyclonal antibodies using other animals.
