Abstract: It is the object of the present invention to provide a condom application strip attaching system capable of automatically attaching a condom application strip having a slit adapted to accept a semen-storing receptacle within a condom. A mandrel to be covered with a condom is vertically attached on the outer margin of a rotating turntable which is indexed to stop at predetermined positions for predetermined times. A manipulating arm support is arranged inside the turntable corresponding to the mandrel. A first condom unrolling device, a second condom unrolling device, a condom application strip manufacturing device, a pressing device, a pair of flat spatulas, a first condom rolling device, a second condom rolling device, and a condom removing device are arranged in sequence outside and along the turntable to effect the entwining of a condom application strip within a condom.

Abstract: A feed for swine containing a casein digestion product of which a principal component is casein phosphopeptide, and a method of breeding a swine which comprises feeding a feed for swine containing 0.01 to 1 part by weight of a casein digestion product of which a principal component is casein phosphopeptide per 100 parts by weight of usual feed for swine. By feeding the feed for swine of the invention, the absorption of minerals, such as calcium and iron is promoted in pregnant sows, resulting in the improvement in the blood properties and milk quality. Piglets are slao improved in the blood properties and ossification degree by feeding the feed for swine of the invention.
