The present invention provides a management method for quantitatively feeding sows based on backfat, which is carried out step by step according to the following stages: the first stage: after the sow is weaned, the second stage: 1-30 days of pregnancy after mating, the third stage: 31-31 days of pregnancy 85 days, the fourth stage: after 85 days of gestation and the fifth stage: after giving birth. Adopting the management method of the present invention to raise sows can adjust the body condition of individual sows to the best state, so that the overall pig population is uniform and healthy, and feeding with evidence can reduce the waste of feed caused by blind feeding, and promote the development of newborn piglets. The weight of the sow is uniform and reasonable, which promotes the maximum productivity of sows and prolongs the reasonable service life of sows.

The invention provides a novel sow feeding method. According to the method, each sow is divided into four different physiological stages including the first half period of gestation, the latter half period of gestation, the suckling period and the weaning estrualization stage, and corresponding fodder is fed at each stage in a matched mode. By the adoption of the method, the problems of sow constipation, poor mammogenesis, great weight loss after weaning and long dioestrus are effectively solved, the problems that the birth weight of piglets is small, uniformity is poor, the weaning weight is low and the rate of survival is not high are also solved, and thus the rate of survival of the piglets at the nursing period and the use efficiency of the sows can be better improved.

A device for interrupting the gestating cycle of a mosquito includes a container having a bottom wall and side walls. A generally porous sheet of material is placed over the upper opening thus formed in the container by securing it to the periphery of the container. Double sided tape, mechanical clips, etc. may be used to attach the porous material to the periphery of the container to cover the open area. The porous sheet of material is farametis and contains apertures that are small enough to prevent an adult mosquito from passing through it but yet allow evaporation of water placed into the container and water molecules through the apertures. A sticky substance is placed on the outer surface of the porous sheet. Water is evaporated from the container and water molecules are released through the apertures into the atmosphere above the porous sheet. Gestating mosquito's are attracted to the device and attempt to enter the container to lay there eggs in the water within the container but can not. Instead, the mosquitoes are immobilized on the surface of the porous material when retained by contact with a sticky substance and prevent it from laying eggs in the container or any other body of water. This breaks the reproductive cycle of the mosquito.

The invention discloses a method for breeding transgenic livestock rich in polyunsaturated fatty acid. The method comprises the following steps of: guiding DNA molecules which have a sequence 1 and a sequence 2 in a sequence list into somatic cells of a mammal to obtain transgenic cells in which a delta-12 fatty acid dehydrogenase and an omega-3 fatty acid dehydrogenase are expressed; cloning embryos by using the transgenic cells as nuclear transfer donor cells and using isolated ovocytes as nuclear transfer acceptor cells by nuclear transfer technology; and transplanting the cloned embryos into a uterus of the livestock by a non-operation method for gestation to obtain the transgenic livestock. The method of the invention can ensure that the delta-12 fatty acid dehydrogenase and the omega-3 fatty acid dehydrogenase are stably expressed in the body of a transgenic pig and that the content of omega-3 polyunsaturated fatty acids (PUFAs) in meat of the livestock is improved obviously.
