Abstract: Integrated classical swine fever virus (CSFV) antigen and antibody detection, elimination of low-level antibody breeding pigs, CSFV vaccine immunization and other technologies, combined with the introduction of healthy reserve breeding herds and the improvement of the pig farm bio-safety system, successfully control and eradication the CSF disease of the farm. A total of 11 568 piglet CSFV antigen negative breeding herds were constructed and keep for 7 consecutive years. The sow mating births rate is 88.15%, the annual output is 24.40 heads, the head consumption is 52.32 kg, the whole group weight ratio is 3.50, the fat pig weight ratio is 2.84, and the female pigs provide 22.36 heads per sow year. According to the data from 2005 to 2015, the pigs group death rate of Liangqi original breeding farm is 5.68% lower than the other farms of Guangxi State-owned Farm Yongxin Animal Husbandry Group Co., Ltd.; Compared to other pig farms of the company, the medicine cost of basic pigs, nursery herds and finishing pigs of the farm were1.05 yuan/kg, 4.75 yuan/head and 7 yuan/head lower than the others and the weight gain cost were 1.37 yuan/kg, 6 yuan/head and 45 yuan/head lower than the others respectively. The price of Pedigree pig, binary mixed and pigs were 750 yuan/head, 155 yuan/head and 35 yuan/head higher, Per head of commercial profit was 140.15 yuan/head higher than the other farms of the company. The Liangqi original breeding farm provided the CSFV antigen negative swine 234300 head in these 7 years.

Abstract: Aloe vera is rich in many active components, such as anthraquinones, anthraquinones and other derivatives have strong antimicrobial activity effects on many plant pathogens. The sterilizing pattern of aloe is similar to that of antibiotics, but its function is superior to antibiotics, and it does not induce mutation and drug resistance bacteria in the process of use, and it can also effectively kill the resistant bacteria caused by the use of antibiotics. At the same time, it can clear th

Abstract: 1. The conduction velocity of action potential of shrimp (Penaeus) giant nerve is very high, may reach 200-300m/sec. So far, besides shrimp, the highest conduction velocity known is the Aαfiber of mammals -~120m/sec. 2. Super-high conduction velocity of shrimp giant nerve is due to its particular structures and electrophysiological properties: (a) large diameter of the nerve, may reach 200µ; (b) thick myelin sheath, may reach 50µ; (c) small axon diameter, only about 10µ or so, in turn, there is big gap between myelin sheath and axon; (d) the area of round shaped Ranvier node-like structure is small; (e) the internodal distance is long; (f) there is Donnan potential in the gap medium. With such structure and physiological properties, as one Ranvier node-like structure is excited, the local current counter acted by Donnan potential in the gap medium, could only run in the thin axon and passes through the small Ranvier node-like structure ahead. The current density through this Ranvier node-like structure will be high and the node will be excited rapidly. Thus, the action potential will go forward fast. b3. The huge space occupied by the giant nerve, together with the formation and maintenance of the thick myelin sheath not only consume appreciably amount of energy but also produce a lot of free radical. These factors prevent the development of such giant nerve in other animals in the course of evolution.

Abstract: The marine oils and fats resources are rich, The biology and animal are survival in the high pressure and the hypoxia, the marine oils and fats containing rich ω-3 PUFA,DHA and EPA, it is impossible that they have special iatrology are replaced by land animal and vegetable oils. The coastal states all are develop the marine oils and fats resources, Present heavy metal and dioxin and some adverse factors, and the oils and fats easy oxidation deterioration, so that the pertinence process technology should be adopted in fishing and store and processing. The market-based approved the content of DHA an EPA should be more than 84%, the different process are selected in refined and enrichment and customization, in order to DHA and EPA appear low variability and invariance. The edible use from the marine oils and fats are prompted.
