“…Lamb meat also has high concentration of iron, which is vital for normal growth, development and helps carry oxygen around the body. Various factors, such as the concentration of minerals in the diet of the animal, hormones, age, gender and region, may cause variations in the mineral composition of the meat (Doyle 1980). Nour and Thonney (1988) reported the same results that is rich in minerals of high bioavailability like iron and zinc.…”

The aim of this study was to compare chemical parameters, fatty acid composition and mineral contents of farm animal meats which are marketed in Turkey. Different kinds of meats were purchased from the meat market including beef, lamb, broiler, turkey, ostrich and quail meat, which are mostly preferred for different reasons by consumers. However, little information exists about the composition of meats of different farm animal species. The results of proximate analysis showed that the high level of protein (24.38%) and low level crude fat (1.19 ± 0.13%) were found in turkey meats, while the low level of protein (18.75%) and high level fat (8.79%) were found in lamb meats. The fatty acid compositions of meats were in the range of 22.68–48.37% for saturated, 21.38–42.45% for monounsaturated and 3.75–47.47% for polyunsaturated acids. The highest micro mineral was determined as zinc (5.7417 ppm) in lamb and ostrich (5.0923 ppm). PRACTICAL APPLICATIONS Consumers attitudes toward meat “safety” greatly affect their overall choices and the variety of meat types available for sale. Some meats are more likely to cause heart disease – saturated fats and trans fats. These fats are usually found in foods from animals such as meat milk, cheese and butter. The dietary saturated fatty acids elevate serum cholesterol concentrations, whereas polyunsaturated fatty acids reduce serum cholesterol concentrations and monounsaturated fatty acids have little or no effect. Therefore, knowledge concerning the exact fatty acid composition of the meat is extremely important for the consumer and processing sector. This study provides comparative information to consumer and processing sector about proximate and fatty acid compositions and mineral contents of beef, lamb, broiler, turkey, ostrich and quail meats.

“…Beef mineral concentrations vary among individuals and are affected by various physiological, environmental, and within breed additive genetic factors (Doyle, 1980;Duan et al, 2011;Zarkadas et al, 1987). Few studies have evaluated mineral concentrations across several sire and dam breeds of cattle.…”

Sire breed effect on beef longissimus mineral concentrations and their relationships with carcass and palatability traits

et al. 2015

The objective of this study was to evaluate sire breed effect on mineral concentration in beef longissimus thoracis (LT) and investigate the correlations between beef mineral concentrations and carcass and palatability traits. Steer progeny (N = 246) from the Germplasm Evaluation project-Cycle VIII were used in this study. In addition to carcass traits, LT was evaluated for mineral concentrations, Warner-Bratzler shear force, and palatability traits. A mixed linear model estimated breed effects on mineral concentrations. No significant sire breed (P ≥ 0.43) or dam breed (P ≥ 0.20) effects were identified for mineral concentrations. Pearson correlation coefficients were calculated among mineral concentrations, carcass, and sensory traits. Zinc concentration was positively correlated (P ≤ 0.05) with total iron (r = 0.14), heme iron (r = 0.13), and magnesium (r = 0.19). Significant (P < 0.05) correlations were identified between non-heme or heme iron and most traits in this study. Magnesium concentration was correlated with all carcass and palatability traits.

Quantification of differences in the effective atomic numbers of healthy and cancerous tissues: A discussion in the context of diagnostics and dosimetry

As dose calculation approaches improve in accuracy, there may be an argument for the explicit inclusion of pathologies. This is more the case for breast, penile, prostate, nasopharyngeal, and stomach cancer, less so for testicular and kidney cancer. The calculated data suggest dual-energy computed tomography could potentially improve lesion identification in the aforementioned organs (with the exception of testicular cancer), with most import in breast imaging. Ultimately, however, the differences are very small. It is likely that the assumption of a generic "tissue ramp" in planning will be sufficient for the foreseeable future, and that the Z differences do not notably aid lesion detection beyond that already facilitated by differences in mass density.
