The values of iodine. saponification and acid PH, composition of fstty acids of grease were analyzed both chemically and by apparatus. The results showed that acid PH, iodine value, saponification value,and unsaturation point are 1.887 and 0.784, 53.90 and 48.32, 98.80 and 100.23. and 60.05% and 58.85% are respectively for masked civet's fat and nutria's oil. Both of masked civet's fat and nutria's oil contain a little of Eicosatetraenoic acid (C-20;4), which is of great significance in nutrition and metabolism for human body. The analysis results indicate that masked civet's oil is similar to nutria's oil in iodine value, saponification value and unsaturation point. Both masked civet's fat and nutria's oil are steady and have highly nutrition. They can be widely exploited and utilized in health protection and cosmetics made industry.展开更多

The results are that the diet prescriptions which contain different digestion energy result in a extremely significant difference in energy digestibility of nutrias(P<0.01 ), the diet prescriptions which contain different digestion energy result in a extremely significant different in crude protein digestibility of nutrias.(P<0.01 ), the linear relationship presents between different digestion energy and energy digestibility, and the relationship coefficients is 0.8,dE(%)=0.62C(%)-7.18 lnCF(%)+57.78 is the regression equation between energy digestibility and crude fiber and carbohydrate in diets; dE=2985.7+18. 10w is the regression equation between weight gaining of nutrias and digestion energy of nutrias; The difference of gaining weight is extremely significant among different groups of nutrias (p<0.01 ).展开更多

Unfortunately, this caused in many instances considerable damage on large rivers along dykes and earthworks in the floodplain areas, leading to an increased risk of bank failures. However, most of these mammals belong to protected species. This work is aimed at showing positive experience in cooperation with universities, research institutes and environmental agencies regarding measures to permanently safeguard the banks using composite erosion control systems with polymer coated steel wire net （as flexible reinforcement component） and a geosynthetic （to promote vegetation growth）. The steel mesh component works as an effective long-term barrier against the intrusion of mammals, discouraging them from digging inside the core of the dyke. An analysis of the sensitive areas to be protected led also to definition of the characteristics of these interventions （length, shape, escape ways, population areas, etc.）. The study will present several additional benefits when using polymer steel nets along dykes, such as： high and durable erosion protection in overflow areas, promotion of fast and effective vegetation growth （increasing stability）, surface protection against ice impacts （in northern regions）, ease of installation, maintenance, ability to conform to irregular shapes of the slope. This work will also present the positive outcome of research studies along dykes in Germany, Austria and in Italy.展开更多
