However, at present,there are still a lot of damage to FAW, and the situation of FAW in China is worrying. In this paper, the concept of FAW and brand are sketched and the importance of FAW is emphasized through analyzing the impact of FAW on the brand and consumption of animal products in China. Advices that more importance should be attached to FAW, animal welfare awareness should be promoted to publicity, and FAW legislation should be speed up are proposed.展开更多

It effectively reduced nitrogen, phosphorus, chemical oxygen demand and biochemical oxygen demand in the water by 67.3%, 73.2%, 38.1% and 15.5%, respectively, during May to September 1998 when the water eutrophication was developing. This could control water eutrophication and produce pearls, shellfish meat and shells. This is an economical and effective way to control water eutrophication by using the ultra strong filtering capability of freshwater pearl mussels.展开更多

The effects of the fish meal replacement by maggot meal on the growth performance of M. anguiUicaudatus were studied by comparing the growth performances and body indica- tors of M. anguillicaudatus fed with different feed groups. The results showed that the final weight, weight gain rate, specific growth rate of the M. anguillicaudatus in group H40 showed no significant difference with the control P 〉0.05 ）, but was significantly higher than that of other groups P 〈0.05 ）. Moreover, except group H40, the feed coefficients of all other groups were significantly higher than that in control group （P 〈0.05 ）. The M. anguillicaudatus in group 1-140 had the highest condition factor and COR and the lowest viscera index, all of which showed significant differences with the other replacement groups （P 〈0.05） but the difference with the control group was not significant （P 〉 0.05）. Thus, a proportion of 40% of the fish meal replaced with maggot meal in the mixed feed for the M. anguilli- caudatus could improve the growth performance and physique indexes of M. anguillicaudatus.展开更多

For several consecutive years, the annual slaughter swine has reached to more than 700 million head, 70 million head of carcasses, about 2 million tons. The number will be even more if cattle, sheep and poultry had been considered. If handled improperly, the large number of carcasses of livestock and poultry will seriously pollute environment and even bring food safety issues and harm to public health security. More and more concern has been attracted on harmless disposal of dead animals. Of all the harmless disposal methods on carcasses of livestock and poultry, the application and research of alkalizalion hydrolysisar （ AH ） are less and only restricted in the higher-level security laboratory field in China. The method of alkalization hydrolysis has the advantages of completely inactivating pathogenic microorganisms （including prions）, no harmful gas, simple operation, low cost, etc, which has the value of research and application. This paper summarized the characteristics and the sterilization effect of alkaline hydrolysis, and discussed the processing and application of AH products of animal carcasses ,meanwhile, introduced the types, research and application state of AH in China, finally, briefly discussed the application prospect of AH in China.展开更多

With the development of artificial insemination,breeding boar plays an increasingly important role in pig production and the welfare of it is becoming more and more important. The problems existing in the welfare of breeding boar in China scale pig farm were analyzed from the aspects of rearing method,feed,environment condition,exercise,artificial semen collection,sexual behavior and environment enrichment and the corresponding measures or countermeasures were put forwards to improve their welfare level.展开更多

Modern scientific research shows that animals, like humans, have complex nervous systems and have certain perception of music. Music can affect animal emotions, affect animal immune function and so on. As people pay more attention to farm animal welfare, more and more researches regard music as a means to improve animal welfare. In this context, the research on the impact of music on the welfare of swine has also begun to attract attention in recent years. This paper briefly reviews the related concepts of animal welfare, its relationship with humans, the mechanism of music and its research on the impact on swine in order to attract more professionals and researchers in animal welfare, music and pig farming.展开更多
