In sub-Saharan Africa (SSA), off-veld ruminant livestock and commercial poultry production fail to meet the demand for meat and eggs. Intensified production to meet the demand requires nutritionally balanced feeds. Competition between humans, livestock and poultry for feed resources present a challenge hence the need for alternative feed resources. Indigenous trees seeds are potential sources of nutrients. Senna siamea, widely distributed in SSA, produces an abundance of seed. We evaluated, by chemical analyses, the potential of hulled (HSSM) and dehulled (DSSM) in S. siamea seed meal to supply nutrients in feeds. DSSM had higher DM, CP, EE, ash, P and gross energy (92.71±0.08%, 47.89±0.03%, 11.39±0.16%, 6.17±0.07%, 1.01±0.03% and 23.13±0.05 MJ/kg DM, respectively) content than HSSM (P<0.05). Amino acids were more concentrated (P<0.05) in the DSSM. HSSM’s CF, NDF, ADF and Ca content was significantly higher (P<0.05) compared to that of the DSSM. The DM, CP, EE and gross energy (GE) content (89.48±0.09%, 21.75±0.09%, 4.71±0.41%, and 20.46±0.04 MJ/kg DM, respectively) of the HSSM though lower compared to in DSSM, are within range of conventional plant-derived dietary protein and energy sources for feeds. DSSM’s CP and GE is higher than that of conventional dietary protein and energy sources for feeds. The TSFAs (27.88±1.36% vs 27.53±0.59%) and TPUFAs (50.42±5.18% vs 53.42±2.12%) proportion of the HSSM and DSSM, respectively were similar. HSSM (21.69±0.18%) had a significantly higher proportion of TMUFAs than DSSM (19.03±0.21%). DSSM had a higher concentration of the fatty acids per unit mass since it had more than double EE content of the HSSM. In HSSM and DSSM palmitic (19.18±0.44% vs 18.63±0.37%), oleic (21.15±0.09% vs 18.45±0.01%) and linoleic acid (43.35 vs 50.62%), respectively were the dominant saturated, monounsaturated and polyunsaturated fatty acids. S. siamea seed meals can potentially be exploited as oleic- and linoleic acid-rich dietary energy and protein sources in livestock and poultry feeds.

In order to expand the range of bakery products for healthy nutrition, documentation on mixed rye-wheat bread «Znatny» with increased biological and nutritional value was developed in 2019. The content of nutrients, the degree of satisfying human need in deficient substances, and product energy value were calculated on the basis of information provided by reference books. Adding the extract of flax and other oil-bearing seeds into the dough while mixing resulted in improvement of rheological properties of the dough and organoleptic parame ters of the bread. Functional characteristics of mixed ryewheat bread “ Znatny” are evaluated according to the content of medium rye flour, light wheat flour, sunflower oil, flax seeds, sesame seeds, and sunseed kernels that enrich the product with a lot of macro- and micronutrients necessary for human body, such as food fibers, mineral substances, vitamins, polyunsaturated fatty acids (PUFA). Due to oil-bearing seeds and sunflower oil on the list of the ingredients mixed rye-wheat bread “Znatny” is characterized by a higher content of PUFA (2.6g), which are necessary, first of all, for proper functioning of the human body. Mixed rye-wheat bread “ Znatny” exceeds the production analog mixed rye-wheat bread “ Zdorovje” in the content of vitamins E, B1 and B2 by 31.8, 13.8 и 11.1 %, respectively; in the content of food fibers (7,0 г/100 г) by 4.5%. The content of mineral substances (К, Са, Мg, Fе) in mixed rye-wheat bread “ Znatny” compared to the production analog is higher by 3.9, 63.4, 22.6, 4.0 %, respectively. In 100 g of mixed rye-wheat bread "Znatny" there are 23.6 % of average daily physiological human need in polyunsaturated fatty acids, 23.3% of food fibers, 16.2% of magnesium, 18.9% of Iron, 29% of Vitamin E, 22% of Vitamin B1

Main Street in Sarasota, Florida. A high-tech medical arts building rises from the east end, the county's historic three-story courthouse is two blocks to the west and sandwiched in between is the First Church of Christ, Scientist. A verse inscribed on the wall behind the pulpit of the church reads: “Divine Love Always Has Met and Always Will Meet Every Human Need.” This is the church where William and Christine Hermanson worshipped. It is just a few steps away from the courthouse where they were convicted of child abuse and third-degree murder for failing to provide conventional medical care for their seven-year-old daughter.This Article is about the intersection of “divine love” and “the best interests of the child.” It is about a pluralistic society where the dominant culture reveres medical science, but where a religious minority shuns and perhaps fears that same medical science. It is also about the struggle among different religious interests to define the legal rights of the citizenry.
