This study analyzed the proximate, minerals, phytochemical profiles and antioxidant capacity of Dysphania ambrosioides (L.) Mosyakin & Clemants and Crassocephalum crepidioides (Benth.) S.Moore leaf meals as potential feed additives. The result of the proximate analysis revealed that C. crepidioides contained higher moisture (6.66%), ash (21.04%), crude fibre (3.85%), crude fat (5.41%), crude protein (17.11%) contents and lower carbohydrate content (45.60%) than D. ambrosioide leaf powder which had 6.31% moisture, 13.69% ash, 3.09% crude fibre, 4.48% crude fat, 15.99% crude protein and 56.12% carbohydrate. The result of the mineral analysis showed that D. ambrosioides contained higher concentration of sodium (19.8ppm), potassium (51.05ppm), calcium (29.18ppm), magnesium (24.1ppm), iron (0.42ppm) manganese (0.33ppm) and zinc (0.91ppm) compared to C. crepidioides leaf meal at sodium (18.71ppm), potassium (41.87ppm), calcium (25.77ppm), magnesium (20.34ppm), iron (0.28ppm) manganese (0.13ppm) and zinc (0.36ppm). The result of the phytochemical analysis revealed that aqueous extract of C. crepidoides possessed higher total phenolic (13.34 mgGAE/g) and flavonoid (2.29 mgrutin/g)) contents than that of D. ambrosioides at (13.07 mgGAE/g) and (1.62 mgrutin/g) respectively. The Tannin and phytate contents were significantly higher in D. ambrosioides leaf meal at 2.39mg/g and 40.28 mg/g respectively, compared to that of C. crepidioides at 2.12mg/g and 29.4mg/g, respectively. The aqueous extract of D. ambrosioides exhibited higher that antioxidant free radical scavenging activity (24.83%) than that of C. crepidioides (16.42%). In conclusion, this study has shown that these two vegetables contained nutrients and antioxidant and could be used as alternative feed additives in animal nutrition.

Minerals have crucial roles in terms of vital function in the organism including hormones, enzymes, cell formation etc. Oxidative stress and related hormones, regarding infectious diseases, affect all functions of body including mineral taking, metabolism and excretion. The purpose of this study was to investigate the effect of the pox disease on blood minerals composition of sheep and lambs. This study was conducted on 20 healthy sheep, 20 poxvirus infected sheep and their lambs (Totally 80 subjects). One-shot blood samples from sheep and lambs were collected and serums were separated immediately. Serum mineral levels were analysed in the atomic absorption spectrophotometer. In general, the level of Cu in infected animals was higher than in healthy ones. Zn, Fe, Mg and Na levels of healthy animals were found higher than infected subjects. The difference between healthy and infected animal groups for serum Ca and K levels was not significant. Positive correlations were found between serum Zn, Fe, Mg and Na levels. However, a negative correlation was found between Cu-Zn and Cu-Fe pairs. Consequently, Cu, Zn, Fe, Mg and Na levels in serum, which are vital for animal organisms, showed significant changes in sheep and their lambs during poxvirus infection. To rapid healing or prevention of the diseases, mineral disorders must be corrected urgently.

In this research, some physicochemical and microbiological characteristics and mineral compositions of marmalades produced by traditional method using Berberis integerrima Bunge (purple barberry), Berberis vulgaris L. (pink barberry), Rosa pimpinellifolia L. (black rosehip), Rosa canina L. (pink rosehip), Malus sylvestris Miller (sour apple), and Vaccinium corymbosum L. (blueberry) wild fruit naturally grown in Bayburt and Trabzon provinces were determined. As a result of the research; pH 2.56-4.18, titration acidity (in terms of citric acid) 0.62-3.40%, dry matter 53.65-64.90%, water soluble dry matter 52.28-64.53%, water activity 0.818-0.894 and HMF (5-hydroxymethyl-2-furfural) were detected in the range of 5.81-53.40 mg/kg. As a result of microbiological analysis, total aerobic mesophilic bacteria, coliform group bacteria and yeast-mold were not detected in any of the samples. In the marmalade samples, the macro minerals Ca, K, P and Mg are ranged from 23.56-425.12 mg/kg, 1275.74-5918.10 mg/kg, 21.98-921.26 mg/kg and 125.50-776.23 mg/kg, respectively. Of the micro-minerals Fe 4034.85-22346.74 µg/kg, Mn 531.63-15065.91 µg/kg, Zn 345.40-6250.76 µg/kg, B 2872.99-7300.37 µg/kg, and Ba were found between 689.31-6455.24 µg/kg. The results of heavy metal analysis showed that marmalade samples were within reliable limits. It is concluded that these fruits, which are not usually consumed as table, but have rich mineral composition, characteristic taste and pleasant aroma, can be evaluated in marmalade production. In the years when the yields of wild fruits are high, it can be processed into products with long shelf life such as jam and marmalade and converted into added value can contribute to the regional economy.

With this research, it was aimed to investigate the content of some heavy metals (Cu, Zn, Fe, Mn) and macro minerals (Mg, Ca, K, Na) in the water resources that meet the water needs of livestock in Iğdır. Water samples were collected from natural springs, surface waters, wells and drilling waters, Aras river and its branches in the region. The data obtained were classified in two different ways and statistical analysis was performed. 1. According to the districts; Central District, Tuzluca, Karakoyunlu, Aralık. 2. According to the type of water resources; Ağrı Mountain spring waters, Ağrı Mountain surface waters, Mountain spring waters, Mountain surface waters, west of Aras river and it’s canals, east of Aras river, Well and Drilling waters. Mineral levels of the water samples were measured by using Atomic Absorption Spectrometer with flame system. According to the district assessment, it was seen that Tuzluca district had lower values compared to other districts. When evaluated according to the type of water source, water mineral content was determined to increase as the waters flowing forward on the surface after reaching to the earth surface It was even found to have become unfit for consumption towards the end. Consequently, with this research, the levels of some heavy metals and macro minerals in the waters used for livestock in the Iğdır region were revealed for the first time with their details. Except for the waters of the East Aras river, the waters of the Iğdır region were found to be of usable quality for animal husbandry.

African eggplants are highly valued constituents of the Nigerian food. However, their nutritional potentials have not been fully tapped due to inadequate information on their nutritional and anti-nutritional qualities. This present study investigated the proximate, minerals, anti-nutrient contents as well as the estimation of mineral ratios and Mineral Safety Index of four selected edible solanum species namely, Solanum anguivi, S. gilo, S. menalogena and S. aethiopicum. The proximate contents (%) ranged from 4.19-5.46 (moisture content), 1.71-2.49 (crude fat), 4.57-5.45 (crude ash), 3.76-4.93 (crude protein), 5.20-6.30 (crude fiber) and 77.14-78.58 (carbohydrate). The solanum species were good sources of energy with total metabolizable energy of 1.458MJ-1.484MJ. The four solanum species contained high K, Ca, Mg, low Fe, Mn, Zn and Cu, while amount of Cd, Ni and Pb were very low. The mineral ratios of K/Na, Ca/Mg, Ca/K, Zn/Cu and [K/(Ca+Mg)] were below the minimum good ratios levels of 1.0, 4.17, 4.0, 8.0 and 2.2 respectively which are good for man. The anti-nutrient contents revealed low phytate, oxalate and cyanide levels. The calculated Phytate/Zn, Phytate/Ca and Oxalate/Ca were lower than the threshold levels and would support absorption and bioavailability of Zn and Ca in the samples while that of Phytate/Fe was above the critical value and this indicates unavailability of iron in these eggplant fruits. The mineral differences observed showed that S. menalogena and S. aethiopicum had greater minerals while the Mineral Safety Index results revealed that the body could not be overloaded with any of the minerals investigated. The eggplants are rich in fiber, ash, carbohydrate and minerals with moderate protein. The low level of the anti-nutrient is good and poses no deleterious effect when consumed. The eggplants have nutritional health benefits; hence, their consumption should be encouraged to address food insecurity in Nigeria
