The paper attempts to analyze and evaluate the investment policy of open-end pension funds. The authoress discusses the investment efficiency of the funds. She also indicates the present and past methods for such evaluation. The paper also describes the types of assets that the pension funds may invest in, along with the investment limits. The ending part of the paper is an evaluation of the investment performance of the entire pension market in the year of good investment results, i.e. 2005. This evaluation allows do demonstrate the influence of the investment policy on the functioning of an open-end investment fund. The results obtained by the funds and the way they invest the money of their members will, after all, determine the level of benefits for future pensioners.

Under current regulations, it is possible to export processed animal proteins originating from tissues of animals other than ruminants. In order to ensure appropriate control, studies were undertaken to adopt a real-time PCR method for the analysis of processed products of animal origin. The material consisted of raw by-products of beef, pork and poultry. In the assays, mitochondrial DNA was used. The modified method is capable of detecting ruminant DNA at a level of 0.025%. The results of validation studies demonstrate that the real-time PCR method can be used in routine tests to identify ruminant DNA in raw animal by-products.

The aim of this paper was to present the results of comparative evaluation of the usefulness of PCR method for the detection and identification of bovine DNA in feeds. In the validation study, the limit of detection for PCR was determined as 0.05% for bovine meat and bone meal (MBM). Among 132 feed samples, bovine DNA was detected in eight (6.06%) samples. In the next stage of the study, sediment and flotate from the investigated samples were examined with PCR. Out of 132 sediment and flotate samples, bovine DNA was detected in eight (6.06%) and nine (6.82%) samples, respectively. On the basis of the results obtained with the use of the PCR, it is possible to state that the molecular biology methods can, at present, be used as supplementary tools for detection and identification of bovine MBM.

The aim of the study was to present the results of comparative evaluation of the usefulness of PCR and microscopic methods for the detection of Processed Animal Protein (PAP) in feedingstuffs. In the validation study, the limit of the detection for PCR was determined on 0.05% for beef, 0.1% for pork and 0.2% for poultry meat and bone meal (MBM). Among 62 doubtful samples of feedingstuffs examined by microscopic method 41 (66.13%) were found as positive. Based on the results obtained with the use of the microscopic and PCR methods it is possible to state that the molecular biology methods can, at present, be used as a supplementary method in PAP detection.
