The production of phytase by three feed-grade filamentous fungi (Aspergillus ficuum NRRL 3135, Mucor racemosus NRRL 1994 and Rhizopus oligosporus NRRL 5905) on four commonly used natural feed ingredients (canola meal, cracked corn, soybean meal, wheat bran) was studied in solid substrate fermentation (SSF). A. ficuum NRRL 3135 had the highest yield [15 IU(More)
This paper deals with the estimation of square of coefficient of variation which is comparatively a more stable quantity using ratio type estimator. Its bias and mean square error (MSE) are found to the first order of approximation. An optimum subclass of estimators is also obtained and a comparative study with the conventional square of sample coefficient(More)
In this paper, we have proposed a generalized class of double sampling estimators based on ratio type estimators for estimating the population mean of the study variable utilizing the available information in the form of known population parameter(s) of two auxiliary variables. The asymptotic expressions of bias and mean square error (MSE) of the proposed(More)
