微生物制剂发酵脱毒菜籽饼养鱼   总被引:1,自引:0,他引:1  
<正> 菜籽饼(菜粕)是一种利用价值很高的高蛋白饲料。菜籽饼含有芥子甙、芥酸、植酸和单宁等抗营养因子,使它的营养价值大打折扣(特别是发霉的菜籽饼)。芥子甙遇芥子酶能在消化道内产生多种有毒物质,使鱼类消化道等损伤;芥酸可使鱼类生长受阻;植酸能与钙、镁、锌结合,影响机体发育;单宁除了味苦,还妨碍蛋白质的消化。 以往菜籽饼类脱毒方法主要有碱液中和法、土埋法、浸泡法、青贮法和氨化处理法,但  相似文献

This paper considers a statistical model for a production frontier that is consistent with the traditional (nonstochastic) definition of a production function given in microeconomic theory. Limiting cases of the model are the familiar average production function and an envelope production function. Maximum-likelihood estimators for the parameters of the model are defined. The three related models are applied in the estimation of a production frontier for the Pastoral Zone of Eastern Australia with use of data from the Australian Grazing Industry Survey.  相似文献

Efficient allocation of resources has usually been couched in risk less terms, partly because statistical techniques did not exist for measuring the impact of varying levels of factors of production on risks associated with production. Now that such techniques are available, methods are required for determining efficient allocations. Such models, particularly those exploiting stochastic efficiency analysis, are illustrated here with respect to empirical risk-sensitive, farm-firm production functions.  相似文献

This paper discusses many of the problems encountered in estimating production functions in a low-income farm area in Saskatchewan. It also ermines the difficulties of interpreting the estimated structural coefficients and their usefulness in policy formulation.
The econometric difficulties discussed in production function estimation are those of function selection and choice and rearmament of variables. Many of the comments are also relevant to other forms of quantitative research.
It is combed that: a great deal of arbitrariness is involved in selecting the appropriate production function model, statistical results often conflict with economic theory, it is impossible to interpret the results in a meaningful manner, and production function research is unable to. provide fruitful information for the type of policy decisions deemed desirable to change the economic structure of low-income farm areas.  相似文献

The identification of local soil variability caused by within‐field differences of macronutrients and ecological features is of paramount importance for the effectiveness of precision agriculture. We present several spatial statistical and econometric techniques to capture local differences in soil variation, ecological characteristics, and yield more effectively than the analytical techniques traditionally used in agronomy. The application of these techniques is illustrated in a case study dealing with precision agriculture in the West African Sahel. The production of millet on acid sandy soils constitutes a typical example of low soil fertility areas exhibiting small absolute but large relative differences in crop production conditions over short distances.  相似文献

Given the importance of Chinese foodgrain production both in China and in the world food market, it is useful to explore the sources of the increased variabilities of China's foodgrain production (Stone and Zhong, 1989). A production function with composite error structure and a heteroscedastic disturbance is applied to cross-section and time-series data from China. The function provides information on the contributions of inputs to production variance and therefore on risk. It is found that production variance is positively related to sown area, chemical fertiliser and irrigation, and is negatively related to electricity use. However, most of the estimates determining the marginal risk effects lack statistical significance. This suggests that the measured controllable factors do not contribute very significantly to Chinese foodgrain production variability.  相似文献

In a recent reappraisal of evidence adduced for allocative efficiency in traditional agriculture, Dillon and Anderson employed a method based on a combination of traditional economic aspects and statistical aspects of estimated production functions. However, their reappraisal involved using marginal rather than the (appropriate) joint distributions of the regression coefficients. This paper investigates the error associated with using the inappropriate marginal distribution in a reassessment of allocative efficiency in wool growing in the Australian pastoral zone.  相似文献

Based on the hypothesis of intertemporal cost minimization, this paper develops an error correction model to explain short-run dynamics of machinery demand in aggregate Canadian agricultural production. The estimated model is subjected to a rigorous sequence of hypothesis tests to check for its statistical validity. In addition, various versions of the model that are nested within the most general model are also tested. Structural parameters of the intertemporal cost minimization problem are recovered from the parameter estimates.  相似文献
