The composition and feeding value of the common heather has been extensively studied by Thomas et al. (1934, 1935, 1953, 1955, 1956). He has shown that as the heather ages the protein content declines. Thus, samples from 2-year-old growths had a crude protein content (on a dry-matter basis) of 11·9% while that of growths 8 years old was 6·5–6·9%. Little or no information, however, appears to be available on the quality of heather protein, as judged by its amino acid composition.

Исследования фракционного состава белков и жирнокислотного состава масел безалкалоидных и малоалкалоидных сортов люпина для производства кормов и продуктов питания являются актуальными в современных социально-экономических условиях, когда требуется найти альтернативу соевым продуктам. В данной работе изучались фракционный состав белков и жирнокислотный состав масла семян 11 образцов малоалкалоидных сортов люпина отечественной селекции трех видов: белого, желтого и узколистного. Самое высокое содержание сырого протеина выявлено в образцах семян желтого люпина, в семенах белого люпина содержание сырого протеина было немного ниже, а все исследованные образцы сортов узколистного люпина характеризовались самым низким содержанием сырого протеина. Суммарное количество растворимых белков в семенах люпина было высоким и изменялось от 84,21 до 92,45 %. Во всех исследованных образцах сортов белого люпина преобладала альбуминовая фракция, в семенах сортов узколистного и желтого люпина – глобулиновая фракция. Содержание сырого жира в семенах разных сортов изменялось от 4,62 до 9,28%. Обнаружены различия в жирнокислотном составе масла семян люпина разной видовой принадлежности. Жирнокислотный состав семян характеризовался преобладанием олеиновой кислоты в масле семян сортов белого люпина, при явном преобладании линолевой кислоты в сортах желтого и узколистного люпина. Researches of protein fractional composition and fatty-acid composition of nonalkaloid and low-alkaloid lupine varieties oils for food production are actual in modern social and economic conditions, when it is required to find an alternative for soybean products. In the present work, the protein fractional composition and fatty acid composition of seeds of 11 low-alkaloid lupine varieties of domestic selection of three species: white, yellow and narrow-leaved lupine were investigated. The highest content of crude protein was detected in seed samples of yellow lupine, the crude protein content in white lupine seeds was slightly lower, and all the studied samples of narrow-leaved lupine were characterized by the lowest crude protein content. The total amount of soluble proteins in lupine seeds was high and varied from 84,21 to 92,45 %. In all examined samples of white lupine varieties the albumin fraction dominated, while in seeds of narrow-leaved and yellow lupine varieties the globulin fraction dominated. The crude fat content in the seeds of the different varieties varied from 4,62 to 9,28%. Differences were found in the fatty acid composition of lupin seed oil of different species. The fatty-acid composition of seeds was characterized by the predominance of oleic acid in the oil of white lupine varieties, with a clear predominance of linoleic acid in yellow and narrow-leaved lupine varieties.

The objective of this paper was to study the amino acid composition of donkey milk inhabiting the Kegety gorge of the Chui region. As well as human milk, donkey and mare’s milk is albumin; the amount of casein is 35-45%, while cow’s milk is casein milk with casein content over 75%. The peculiarity of albumin milk is a higher biological and nutritional value, due to better amino acid balance, high sugar content and the ability to form small, delicate flakes when souring. In terms of its properties, albumin milk is closest to human milk and is the best substitute for it. The obtained results showed that the quantitative content of 7 essential amino acids out of 8, such as lysine, phenylalanine, leucine, isoleucine, methionine, valine, threonine is relatively high compared to other amino acids. Despite the absence of tryptophan in donkey milk, the percentage of 8 essential amino acids in donkey milk protein exceeds that in mare and cow’s milk.

SUMMARYThough bitter white lupin (Lupinus albus L.) is a traditional crop in Ethiopia, sweet lupins are new to the country. As a result, the nutritional value of low-alkaloid lupins has not been evaluated under Ethiopian conditions. Crude protein, amino acid and alkaloid contents of 16 cultivars of three annual lupin species grown in four lupin growing locations (Merawi, Finoteselam, Kossober-1 and Kossober-2) of Ethiopia were evaluated. Location × cultivar interaction was a significant source of variation for all traits (p < 0.0001). In all locations, blue entries had either similar (p ≥ 0.0584) or higher (p ≤ 0.0235) forage crude protein content than the Local Landrace, white group and yellow entry. Compared with the Local Landrace, white and blue entries, the sole yellow entry had higher (p ≤ 0.0148) seed crude protein content at all locations except at Kossober-2, where it had similar (p = 0.8460) crude protein content as white entries. The Local Landrace had the highest forage and seed alkaloid contents. However, sweet blue Vitabor and Sanabor entries had the lowest forage and seed alkaloid contents, respectively. Low alkaloid and higher crude protein contents of sweet lupins grown in Ethiopia show the possibility to use sweet lupin forage and seeds as cheap home-grown protein source for livestock feed and human food in the country. However, for more reliable information, the laboratory results need to be verified by animal and human evaluations of the crop.

The fluid was separated from the immature soft enamel of porcine permanent teeth in the secretory stage according to procedures reported previously (Aoba and Moreno, 1987). The protein content of the fluid was about 2.8% w/v; its amino-acid composition was characterized by high contents of Pro, Glx, Leu, and His, showing composition similar to that of the 20 kilo-dalton (kd) amelogenin or its C-terminal segments. The two major protein species in the fluid had apparent molecular weights of 13 kd and 11 kd, as determined by SDS electrophoresis; the N-terminal residue of the former was Leu, while that of the latter was Ala. The C-terminal sequence of both of them was -Met-Phe-Ser. By comparison with the published sequence of 20-kd porcine amelogenin, it is concluded that the main fluid constituents were derived by cleavages of N-terminal segments from the 20-kd amelogenin.
