In aquacul- ture, probiotics are generally used to improve the ecological environment and inhibit pathogenic microorganisms, thereby reducing the incidence of diseases.They have been more and more commonly used in the intensive aquaculture of shrimp, and require certain nutritional conditions and need to reach a certain number to produce a good performance. In this paper, the basic nutrition requirements of the common- ly-used probiotic Bacillus and its water quality-improving effect were investigated to provide theoretical guidance for production.展开更多

These different indexes were compared for using them in assessing the body condition. There was a linear relationship (y=0.9444x-20.139; r=0.9454; p<0.01) between RKFI and KMFI. A linear relationship (y=0.9348x+1.1843; r=0.9875; P<0.01) between TMFI and FMFI also occurred for gazelles. There was a curvilinear relationship (y=31.44Ln(x) -44.403; r=0.8643; P<0.01) between FMFI and RKFI. FMFI remained high, while RKFI decreased to a certain extent. After most of the kidney fat was used, the femur marrow fat abruptly decreased. The results showed that the kidney fat index is more adequate for evaluating the population nutrition in good condition, but marrow fat index was more useful for assessing in poorer nutritional condition.展开更多
