In this study the "special cocktail enzyme" for double-low rapeseed meal(DLRM) based diet were screened out by the in vitro incubation system, and a feeding and digestibility trials were conducted to validate the effects of the "special cocktail enzyme" application to DLRM based diets for pigs and broilers, and to evaluate the relationship between nutrient digestibility and animal performance.

A field experiment was conducted to study the different effects of special compound fertilizer.

Aim to fertilizer present situation of the current tobacco production in Chuxiong state,conventional for of the status and raw materials of Chinese cigarettes on request to tobacco raw,and the application of application of the conventional Flue-cured tobacco special compound fertilizer exist drawbacks,this paper used field experiments, Comparison with the same field,demonstration and promoting.

Production of feed compound enzymes from cottonseed husk by fermentation;

Study on conditions for producing feed compound enzymes;

Study on fermentation technology of compound enzymes employed to pig feed;

Extracting conditions and stability of feed enzyme-complex;

The solid plate fermentation process of this strain was optimized and animal feeding experiments were carried out,the results showed that the feed enzyme-complex produced by strain.
