Abstract Introduction. Foodstuffs of special nutritional use and dietary supplements, especially in the case of sportsmen, have been known and widely used in human nutrition, nourishment, and convalescence for many years. Aim. The aim of the study was to assess the nutritional value of two groups of special dietary formulations and, in particular, to compare the nutrient and energy content declared by producers with that revealed by the present analyses. Material and methods. The nutritional value of two groups of formulations was assessed. The first group comprised formulations for undernourished subjects or those with contraindications to use diets with normal content of proteins and/or fats. The second group of formulations included products intended for strengthening the organism and targeted mainly at sportsmen. Samples of purchased products were analyzed for the content of basic components: dry matter, total protein, crude fat, crude ash, and structural carbohydrates. The content of carbohydrates and energy value was calculated mathematically. Additionally, the content of selected minerals (calcium, potassium, sodium, magnesium, iron, zinc, copper, manganese) was determined. Results. The content of carbohydrates, proteins, and especially fat in the chemical composition of the analyzed products declared by the producers differed from the levels determined in this study. In the mineral composition, differences were noted in the content of macroelements, while the content of micronutrients did not differ from the declared values. Despite the differences in the composition, the declared and calculated calorific values in all formulations were similar. Conclusions. There were differences between the declared and determined contents of nutrients in the analyzed formulations. The labels of the special-purpose industrial formulations purchased in pharmacies provided more information about their composition and nutritional value, whereas the information presented on the labels of the athlete supplements were less informative. Consumption of the supplements, in particular those dedicated for sportsmen, should be supervised by a doctor or dietitian.

The study examined the yield, chemical composition and nutritive value of energy tree leaves under one year rotation, and considered the methods and results in the entire tree utilization. The proportion of leaves was 31 % for Salix cv. Aquatica and 16 % for S. viminalis of the total biomass yield. The dry matter yield of leaves amounted to 3—5 tn DM/ha. The average chemical composition of willow leaves was as follows: dry matter 27 %, ash 7.7 %, crude protein 19.5 %, ether extract 4.9 %, and crude fibre 14.1 %. The content of tannins was 4.1 % in willow leaves and 3.4 % in alder leaves. Fertilization had a significant effect on the ash and protein contents of willow leaves. Crude fibre content of alder leaves was higher compared to willow leaves. In vitro digestibility of willow leaves was 64 % for organic matter and pepsine-HCI soluble protein was 65 % on average. Fertilization improved the digestibility 6—8 %-units. Calcium content of willow leaves was 10g/kg DM, phosphorus 3g/kg DM and magnesium 2.8 g/kg DM. The amount of trace elements was considerably high. On account of the high content of protein and minerals willow leaves are a considerable source of feed for domestic animals or wild ruminants. The harvesting and conservation of leaves is still a technical question that has to be resolved.

This research aimed to improve dairy production and increase the income of dairy farmers using locally available feed resources. Small-scale milk producers rely heavily on available feed resources in the locality which are either indigenous in the area or introduced species for feed and nutrition of their dairy cattle and buffalos. Their milk output depends mainly on seasonal fluctuations in the quality and quantity of natural forage. Crop residues such as corn stover and rice straw which are high in fiber but low in nutrients serve as a feed supplement and filler to the daily diets of dairy cattle and buffalos. Cagayan Valley is an ear of top corn and rice-producing region. The potential of crop residues as feed supplements or raw materials of dairy cattle/buffalo feed mix is great. But dairy farmers still face the scarcity problem of quality feed resources for dairy animals especially during the dry season. The supply of forage is very low during the dry spell. Inadequate feed mix and low nutritive value of feed mix result in low or no milk production. Producing green corn and ensiling it to produce green corn silage preserves and prolong the storage life of forages. In this way, a stable supply of feed mix for dairy animals is assured year-round. Type of Paper: Empirical. Keywords: adoption and commercialization, dairy industry, financial viability, green-corn silage production, indigenous grasses, smallholder farmers.

In view of growing requirements of the food industry regarding elderberries (genus Sambucus), a need to increase their productivity and improve their chemical composition has emerged. With this purpose in mind, numerous elderberry interspecific hybrids have been created. In the present work, the content of minerals in their crucial plant parts was studied. It was also investigated whether superior genotypes regarding the mineral composition of berries and inflorescences could be predicted at early stages of plant development. The results showed that elderberry leaves contained the highest amounts of Ca, Mg, Mn, Zn, and Sr, while K and P were predominant in fruit stalks. Fe and Al prevailed in roots and Cu in bark. Although berries showed lower mineral content compared to other plant parts, their mineral content is not negligible and could be comparable to other commonly consumed berries. Genotypes with a favorable mineral content of inflorescences and berries could be predicted on the basis of known mineral composition of their shoots and leaves. The study also indicates that S. nigra genotypes and the majority of interspecific hybrids analyzed are suitable for further genetic breeding or cultivation.

Forest rangelands contribute largely to goat diets in the Mediterranean area. Information about browsed plant quality is essential for adequate feeding management. The purpose of this study was to evaluate the temporal changes in chemical composition and in vitro digestibility of the main plant species selected by goats in the Southern Mediterranean forest rangeland during two consecutive years; these were very contrasted (dry and wet). The browsed species were composed of herbaceous, eleven shrubs, and four tree species. Overall, large variability in chemical composition, in vitro organic matter digestibility (IVOMD), and metabolizable energy (ME) was observed among species, grazing season (spring, summer, and autumn), and years within each species. Crude protein (CP) content varied from 60 to 240 g/kg dry matter (DM). The fiber fractions, except for Quercus suber, increased significantly by advancing maturity. Due to the water stress, the lignin level presented a higher value during the spring of the dry year. Condensed tannin (CT) content varied from 2 to 184 g/kg DM. CP, IVOMD, and ME showed a negative correlation with lignin and CT. Based on the results presented herein, it is concluded that the nutritive value of the browsed plant species was highest in the spring and lowest during the summer and autumn of both studied years. With a good grazing management strategy, the selected plant species by goats could guarantee high-quality feeding resources throughout the year.
