An analysis chemical composition of 33 samples of five cereal grains harvested in oneyear led to a conclusion that the greatest variations and statistically significant differences (P≤0.01) among cereals existed in their content of crude protein, crude fibre and the following fractions of dietary fibre: NDF,ADF, TDF, IDF and SDF.Analyzed winter wheat and winter rye varieties differ significantly (P≤0.01) from other cereal grains in their content of magnesium, potassium, sodium, phosphorus, manganese, zinc and show a statistically significant difference (P≤0.05) in the content of calcium and copper. The average total content of amino acids was highest in wheat and lowest in winter barley. Lysine was found to be the first amino acid limiting (CS) the quality of protein in all analyzed varieties of cereal grains, with the exception of rye, while tryptophan was found to be such an amino acid for animals (WE). The high content of essential amino acids (EAA) was reflected in EAAI, which forWH ranged from 71% (spring barley) to 84% (winter triticale), and forWE from 51% (winter barley) to 60% (winter triticale).

Polycratic reversed-phase high-performance liquid chromatography (RPHPLC) was used for estimation of the octanol/water partition coefficient for three highly hydrophobic long chain orcinol homologs. The homologs studied (C 15:0, C 17:0 and C 19:0) showed high preference for hydrophobic phase as evidenced by their high octanol/water partition coefficient (log P o/w ) values of 7.02-7.74; 8.71-9.47 and 10.49-11.32 for the 95% prediction interval, respectively. Experimentally estimated values were compared with log P values calculated with the use of several fragmental systems. The experimental values of log P o/w are in best agreement to those calculated with the use of the Klopman system (Klopman, Gv Namboodiri, K. & Schochet, M., 1985, /. Comput. Chem. 6,28-38). The lack of appropriate standard compounds with known log P 0/w in the range over 6 markedly affected the accuracy of experimental determinations.

Seed dormancy is of particular importance in the cultivation of cereals, as it directly affects the quality of crop yield. If the dormancy period is too short, this may lead to pre-harvest sprouting, whereas a dormancy period that is too long may cause uneven germination; both of these scenarios are associated with economic losses. Most enzymes engaged in the metabolism of abscisic acid (ABA) have been identified, and significant progress has been made in understanding the role of this phytohormone in the induction and maintenance of dormancy, mainly as a result of research conducted in Arabi-dopsis. Much less is known about the metabolism and function of ABA in cereal grains, especially in relation to dormancy and germination. This review focuses on the regulation of ABA metabolism in dormant and non-dormant cereal grains, in both the dry state and upon imbibition. Moreover, this review describes the influence of factors such as after-ripening, light, temperature, nitric oxide, and reactive oxygen species (ROS) on the dormancy and germination of cereal grains. These factors, with the exception of ROS, appear to affect the level of dormancy and germination of grains through regulation of ABA metabolism.

Cereal grain resorcinolic lipids (S-n-alk(en)ylresorcinols) at micromolar concentrations are able to protect the erythrocyte membrane against hydrogen peroxide-induced lipid oxidation. The antioxidative effect is dependent upon chain length of alkylresorcinol molecules. The C15:0 homolog (IC50 of 10 uM) exhibited strongest activity whereas for long chain homologs (C19: 0 and C23 : 0) IC50 values were higher, 32.5 and 59 uM, respectively. The protective effect of alkylresorcinolic antioxidants was also dependent on their incorporation into the membrane, that is governed by their water-membrane partition coefficient The results obtained show that alkylresorcinols should be recognized as hydrophobic, membrane-localised antioxidants.

Because dilution plating is more labor intensive than direct plating, we would like to propose the use of a direct plating technique for estimation of Penicillium verrucosum abundance in cereal grain in incubation studies, with use of very selective and indicative for the fungus agar DYSG medium. The proposed method is based on the measurement of the diameter of P. verrucosum colonies grown around cereal kernels placed on DYSG medium. In three different experiments wheat grain contained a great range of P. verrucosum CFU number (from <25 to 77 x 10⁶ per 1 g). When P. verrucosum CFU number was at least as high as 10² per 1 g of the grain, 100% of the wheat kernels, placed on the surface of DYSG medium, were surrounded by colonies of P. verrucosum. The diameter (x, mm) of P. verrucosum colonies surrounding wheat kernels on DYSG medium was correlated with the fungal CFU number (y) on the wheat grain. The relationship is described by the exponential regression equation (y = 0.1258 e 0.9309x, R²=0.96). The relationship became linear (y = 0.404 x-0.901, R² = 0.96) after transformation of P. verrucosum CFU numbers to logarithms to base 10.

This study investigated insect pest infestation of maize, millet, sorghum, rice and wheat grains traded in the three main markets namely Monday, Baga-Road and Custom-Park markets in Maiduguri, Borno state, Nigeria. Sampling lasted from January to June 2012. Samples per grain type, each weighing one kilogram, were obtained every two weeks from ten randomly selected traders per market. Each sample was sieved in the laboratory to recover all adult insects present, both at sampling and also after one month stay (laid out in a completely randomized design). In each market, Sitophilus zeamais Motschulsky and Rhyzopertha dominica (F.) followed by Tribolium castaneum Herbst, Sitophilus oryzae (Linnaeus), Trogoderma granarium (Everts) or Cryptolestes sp. were the insect pests commonly found attacking more (between two to five) grain types. Observed highest and lowest mean insect numbers were respectively by S. zeamais in maize grains (12.13 individuals in Monday market) and T. granarium in wheat grains (0.13 individuals in Baga-Road market). Results unveil that among three markets, higher mean total numbers of insects were present in maize, rice or wheat (18-33). For all grain types, the mean numbers of damaged grains were significantly higher in Monday (53-357) and Custom-Park (46-302) than in Baga-Road (17-109) markets. Furthermore, the mean total number of damaged grains across markets was significantly higher maize, followed by rice and wheat (55-231) than in other grain types (37-41). The implications of all these results on insect infestation of different cereal grain types sold in these markets are discussed.

Two flour types (unpolished flour and polished one) and flour textures (grits and fine) of five cereal grains made up of millet, rice, wheat, sorghum and maize were evaluated under laboratory conditions for their susceptibility and progeny development in Tribolium castaneum in hot dry and cool humid seasons. T. castaneum thrived better during the cool humid season than the hot dry season. Polished flour was less susceptible to infestation and supported lower population of the beetles than unpolished flour. Index of susceptibility was 19.65-20.76% in unpolished flour and 18.89-19.76% in polished flour. The number of progeny that developed were 102.6-135.1 and 98.2-121.4 in unpolished and polished flours, respectively. Similarly, grit flour was significantly less susceptible than fine flour in both seasons. Rice, wheat and sorghum flours were less susceptible and supported significantly lower populations of T. castaneum than millet and maize flours in both seasons. Polished wheat flour supported least progeny number than the flour types of the other cereal grains. Conversely, significantly higher number of progeny developed in polished flour of millet and maize and unpolished flour of wheat. Millet fine flour and maize fine or grit flours were significantly more susceptible to infestation than flours of the other cereal grains.

The aim of the study was to evaluate the effect of replacing cereal grains and soyabean oilmeal with rapeseed cake or glycerine in the rations of high-yielding cows. The experiment was carried out on 56 Polish HF cows allotted to 4 groups of 14 animals according to body weight, milk yield, and parity. The cows were fed rations differing in protein and energy content from 6 weeks before calving to 12 weeks of lactation. The basal diet of all groups was composed of silages, meadow hay and concentrate feeds. In the experimental groups, the cereal grains and soyabean oilmeal fed to the control group (C) were replaced by rapeseed cake (30%; groups RC and RCW6 ) or glycerine (5%, group G). For the entire experimental period, no statistical differences were found among the groups in the daily intake of dry matter and other nutrients, except PDIE. The control group cows produced about 1.2 kg/day less milk (P>0.05), but the contents of dry matter, fat, protein, lactose, and urea in milk were similar. The highest concentration of free fatty acids and β-hydroxybutyric acid were found in the milk of the control cows. Introducing 5% glycerol into the diet did not cause any significant changes in production parameters. The serum metabolite profile of cows fed the experimental diets suggests that these cows could have been at a lower risk of ketosis.
