Quantitative computed tomography has been used extensively to measure bone mineral density; particularly in the vertebral column and in the proximal portion of the femur in human beings with osteoporosis. Other potential applications of this technique include evaluation of bone adjacent to metallic endoprostheses and evaluation of fractures as they heal. Unfortunately, metal causes severe image degradation, principally seen as starburst streaking. One method used to decrease these artifacts is by imaging less-attenuating materials, such as titanium alloy. Titanium decreases image degradation sufficiently to allow accurate determination of the geometric properties of cadaveric bone. In our study, the effect of a titanium segmental endoprosthesis on bone mineral density measurement was determined by use of bone specimens from dogs and calibration standards. Titanium decreased the bone mineral density of calibration solutions from 6.8 (500 mg/cm3) to 17.7% (250 mg/cm3), and increased bone mineral density of cortical bone by 5.3%. Titanium did not affect the repeatability of these scans, indicating that the error caused by titanium was systematic and can be corrected. Our data were suggestive that quantitative computed tomography can be used to measure bone mineral density of cortical bone adjacent to titanium endoprostheses, with a predictable increase in density measurement.

Palm kernel cake (PKC) has long been known to be an importantingredient for the formulation of animal feeds. However the recommended levels of inclusion seem to vary from one reporter to another. This factor is considered important especially when formulating feeds for nonruminant diets. The variation of its major constituents such as protein, fibre and fat contents is said to depend on the sources, oil removal technology and the efficiency of oil extraction from the kernel. For comparison,a set of compilation data of 300 local PKC samples from the past years on these basic nutritional constituents were studied.Majority of the samples analysed were from southern region of Peninsular Malaysia meant for animal feeds. Mean percentagevalues and their respective standard deviations were as follows; crude protein 16.1±1.65, crude fibre 19.3±4.22, crude ash5.9±2.48, ether extract 5.6±3.36, dry matter 91.3±2.65, and metabolisable energy 7.75 MJ/kg. The objective of the study was to observe the distribution pattern of these values compared to other surveys. From this study, the highest relative standarddeviation (RSD) reached 60% for ether extract, followed by ash 42.1%, and crude fibre 21.8%. From the variation point of view,periodical results for quality control of PKC must be initiated as an useful indicator for its accuracy of each diet formulation.

In this study five samples each of serum glucose, serum cholesterol and uric acid contents were measured in Fayoumi, Rhode Island Red, Parent desi, desi Fl and desi F2 strains of chickens. Cholesterol contents were found to be lowest in desi F2 chickens whereas in other strains there was least significant difference, which can be attributed to reduced lipogenic activity in desi F2 generation. When five samples each of meat from two locations i.e. breast and thigh was subjected to proximate analysis it was found that there was no difference (P greater than 0.05) in crude protein, crude fat, total ash and moisture contents regardless of sex and strains. Dry matter contents differed (P less than 0.05) in breast meat and found to be lowest in Parent desi stocks.

The rapid method for predicting palm kernel cake quality with near infrared reflectance spectroscopy was investigated. Chemical tests for moisture, ash, crude protein, crude fat, crude fibre, total digestible nutrients (TDN), nitrogen free extract (NFE), metabolisable energy (ME), calcium and phosphorous were time
consuming and involve high cost. This technology can save considerable time by testing all the parameters simultaneously;
however accurate calibration of the equipment is essential. Near infrared (NIR) partial least square (PLS) regression models for determination of several palm kernel cake quality parameters were
developed from NIRFlex Model N-500 (Buchi). In general, reliable prediction results were obtained for the TDN (SEP = 0.85 r2 = 0.99), NFE (SEP = 0.42 r2 = 0.97) and crude protein (SEP = 0.57 r2 = 0.98)
PLS regression models.

This trial was conducted to study effect of freezing on quality of broiler meat after freezing. Meat samples were taken from two sites such as breast and thigh. The weight, moisture, protein, fat and ash contents were analyzed before and after freezing at -25 degree centigrade for 15 days using methods given in AOAC, (1990). It was observed that protein, fat and ash contents were not changed consequent to freezing. There was loss (P less than 0.05) in weight which can be attributed to drip loss when meat is thawed. This study provided evidence that there is no change in nutrients when meat is subjected to freezing.
