Potato tuber colour is an important factor that influences consumer preferences. Eastern plain region of India contributes about 50% of total potato acreage and production. Consumers in this region generally prefer red skinned varieties. Growing awareness for nutrient rich food can create a niche market for nutritious potatoes. Potato is crop of choice for mineral biofortification owing to better mineral bioavailability due to its high ascorbic acid and minimal phytate content. Iron and zinc are the essentially required minerals for good health. Considering the nutritional importance of these elements and wider prevalence of their deficiency in Indian sub-continent, thirteen Eastern regions red skinned advanced hybrids and varieties were evaluated to find the genetic diversity for iron and zinc content. A significant wide range of contents was observed for both the elements. High heritability of both mineral suggests feasibility of selecting genotypes for breeding nutrient rich varieties. Identified genotypes can be utilised as parental lines for future breeding programme and can be released as nutrient rich potato variety.

The nutritive value of 26 cultivars of dry, mature subterranean clover was evaluated at Shenton Park, Perth, Western Australia. The cultivars were divided into 3 maturity groups according to flowering time and each cultivar was sown in blocks comprising 4 replicates. The plots were grazed by sheep at 2-week intervals during the growing season. Dry mature plant material and soil were sampled in summer to examine the effect of grazing and cultivar on seed yield and nutritive value of feed residues. Cultivars heavily grazed in spring had a low herbage mass. There was no difference in seed yield and seed weight between heavily and lightly grazed cultivars. Dry matter digestibility and mineral content of dry residues was inconsistent for the 2 grazing treatments. The dry matter digestibility of dry, mature subterranean clover ranged from 40 to 56%, with a wide range of crude fibre, nitrogen and mineral content for the 26 cultivars. While most minerals in the dry residues were above the requirement for sheep, 7 cultivars had a zinc content less than the maintenance requirement for sheep. There was an imbalance for all cultivars in calcium: phosphorus with a range of 4–10: 1. Concurrent estimates on the yield and composition of seed indicated that seed can be resource of minerals for grazing animals in summer. Most cultivars had a seed yield over 100 g/m2 with that of 9 cultivars being over 130 g/m2. Seed was rich in nitrogen, sodium, phosphorus, potassium, magnesium, zinc and copper, and poor in sodium, calcium and manganese. However, there were no cultivars with an appropriate ratio of calcium and phosphorus. The imbalance in nitrogen and sulfur was a result of high nitrogen content with the ratio ranging from 19: 1 to 29: 1.

Evaluation of the quality of complementary flour and its nutritional adequacy in relation to infant’s nutritional requirements was done to four different types of complementary flour (composite cereals with groundnuts, maize, millet and sorghum). The collected samples were analysed for determination of macronutrient, micronutrients and phytate content. The mean protein content in all types of complementary flour was 7.30 ± 2.52 g/100 g. A significant difference in protein content between composite cereals (p ≤ 0.001) and other types of cereals-based foods was observed. Fat and iron content were found to be inadequate in all types of complementary flours. Phytate content ranged from 59.47 - 1176.8 mg/100 g, the highest content was observed in sorghum. On the other hand, the mean iron and zinc content in all types of complementary flour was 5.25 ± 1.35 mg/100 g and 2.99 ± 1.36 mg/100 g respectively. The molar ratios of phytate:iron and phytate:zinc were at a level that would tend to inhibit bioavailability of iron and zinc in 97% and 45% of analysed samples respectively. An association between anaemia and phytate:iron molar ratio (AOR = 4.2, 95%, 1.2 - 6.9) was observed. The quality and adequacy of nutrients in cereal-based complementary flour has shown to be inadequate and likely to be compromised by the presence of phytate.

AbstractThe main objectives of this study were to compare the prediction accuracy of different Bayesian methods for traits with a wide range of genetic architecture using simulation and real data and to assess the sensitivity of these methods to the violation of their assumptions. For the simulation study, different scenarios were implemented based on two traits with low or high heritability and different numbers of QTL and the distribution of their effects. For real data analysis, a German Holstein dataset for milk fat percentage, milk yield, and somatic cell score was used. The simulation results showed that, with the exception of the Bayes R, the other methods were sensitive to changes in the number of QTLs and distribution of QTL effects. Having a distribution of QTL effects, similar to what different Bayesian methods assume for estimating marker effects, did not improve their prediction accuracy. The Bayes B method gave higher or equal accuracy rather than the rest. The real data analysis showed that similar to scenarios with a large number of QTLs in the simulation, there was no difference between the accuracies of the different methods for any of the traits.

This study investigated the influence of three soil moisture irrigation regimes on concentration of seed iron and zinc content of four biofortified bean varieties promoted for eradication of malnutrition in Sud-Kivu highlands. A field experiment was conducted in the Hogola marsh highlands during two cultural seasons B2013 and B2014. The experiment design was a RCBD with a split plot arrangement where the main plots were 110 m2 and split plots 20 m2. A strategic application of homogenisation of the experimental site’s soil fertility by chemical fertilizers of the type: CaCO3, KCl and DAP was conducted out. Four biofortified varieties (CODMLB001, RWR2245, HM21-7 and RWK10) constituted main factor, while water regimes respectively [bottom of the slope: R1 = 48% soil moisture, at the middle of the slope R2 = 37% soil moisture and at the top of the slope: R3 = 29% soil moisture according to the gradient of humidity] represented secondary factor and seasonality, tertiary factor. The study showed that the concentrations of iron and zinc were highly correlated with soil moisture regimes. The variety HM21-7 demonstrated better adaptability because it showed a low rate of reduction of iron and zinc concentration under the three soil moisture regimes and was therefore best suited to fight malnutrition in the Sud-Kivu province.

The experiment was conducted to evaluate the nutritional and cooking properties of some rice varieties collected from the farmers of Noakhali region of Bangladesh. Noakhali district is situated in the coastal belt of the country and this area also termed as ‘char’ land. All of the selected varieties were grown in saline soil condition. For assessment of nutritional quality, protein, iron and zinc content were estimated. The protein, iron and zinc content ranged from 6.75 to 8.63%, 7.09 to 9.84ppm, 24.52 to 32.34ppm, respectively. The highest amount of protein, iron and zinc were found in Kajalshail variety. All of the rice varieties showed significant variation for all cooking properties studied in this work. The volume expansion ratio (VER) was varied from 1.89 to 2.20. The kernel elongation ratio (KER) was greater than 1.1 in all varieties except Carandol. On cooking Kajalshail variety exhibited highest VER and KER 2.20 and 1.19, respectively. Based on the gel consistency (GC) test, the average GC values ranged from 39.73 to 92.53mm and varieties were categorized as hard, medium and soft. On the basis of alkali spreading value (ASV) the varieties were classified into three groups namely- low, intermediate and high. ASV was found significantly and negatively correlated with gelatinization temperature (GT). The Kajalshail variety was found to have the better nutritional and cooking quality among all varieties.

Rice is one of the most important staple food crops for billions of people throughout the world. It is the cheapest source of dietary energy, protein and minerals for people but poor in micronutrients such as Fe and Zn to eliminate “hidden hunger”. In the present study, a population of 126recombinant inbred lines developed from a cross between Lemont X Satabdi (IET 4786) were used to identify high iron and zinc content coupled with yield and yield attributing traits. Analysis of Variance revealed that a considerable variation in iron and zinc existed among genotypes. The correlation study revealed that number of filled grain was positively associated with panicle length and yield per plant and number of panicles, but no significant positive correlation was observed between grain zinc content and iron content. Zinc and iron content of rice was estimated using Atomic Absorption Spectrophotometer and the samples were prepared by tri-acid digestion method. Among RIL lines, the line 57, 97,120, 48, 99, 124 contained more than 30 ppm Fe and the lines 24, 6, 9, 23, 29, 125 were found to possess more than 50 ppm Zn. The lines 9,6,48 and 57 were recorded to be high yielding with high zinc and Fe content in grain and in future these four lines look promising for multi location trial also. These high Fe and Zn content genotypes can be utilized in future breeding programme as a donor or good source for bio fortification of rice genotypes.

Abstract The aim of the study was to determine the quality and nutritional value of meat originating from pigs of Polish native pure breeds - the Puławska and Złotnicka Spotted as well as the commercial four-breed crossbreds F1 (Large White × Polish Landrace) × F1 (Duroc × Pietrain). Physicochemical properties of meat were evaluated, such as acidity, water holding capacity, tenderness, and color parameters. In addition, functional properties of meat were determined: nutritional value, mineral content and fatty acid profile. The dietetic indices of meat were also determined. The smallest acidity of muscle tissue was characteristic of the meat of the Puławska breed and the smallest meat drip loss was found in both native breeds (P≤0.01). This can confirm their greater technological suitability. The most tender was meat obtained from pigs of the Puławska breed (36.07 N/cm2). The darker color was characteristic of the pig meat of the Złotnicka Spotted breed (L* = 49.19) (P≤0.01). Meat of all three groups of the tested pigs had the quality characteristics related to normal meat. The highest content of protein was found in the Złotnicka Spotted meat (25.23%) at optimum fat content (2.25%). The high content of ash (1.63%) recorded in the Złotnicka Spotted meat meant higher content of macro and microelements, especially iron and zinc, as compared to meat of the four-breed crossbreds (P≤0.01). The highest amount of monounsaturated fatty acids (52.72%) was recorded in porcine meat of the Puławska breed, while content of polyunsaturated fatty acids was the highest in meat of the four-breed crossbreds (16.77% vs. 9.32% and 15.19%) (P≤0.01). No differences were found between the groups tested for atherogenic index. In terms of most physicochemical and functional characteristics, meat of native pig breeds was superior to the meat of commercial pigs from mass-production.

The Russian market of biologically active additives, which include pancreatine and pancreatic enzymes — amylase, protease, lipase, has been analyzed. It was established that the study group is represented by a wide range (approximately 150 names), which is represented mainly by foreign manufacturers (approximately 80%). The monotonous tendency to increase sales by volume in all regions of the Russian Federation over the past 5 years has been analyzed. It should be noted that, today consumer preferences biologically active additives of domestic production despite the significant share of imported dietary supplements in the supply structure. High demand is primarily due to the accessibility and increased trust and loyalty of modern consumers to national producers of biologically active additives .
