Aim. The aim is to identify the differences in the accumulation of manganese, zinc, copper and molybdenum in the hair of farm animals (cows and goats) and their spatial differentiation in the valley of the Lower Dniester. Methods. Sampling and sample preparation were carried out in accordance with generally accepted methods. The determination of metal content in hair samples was carried out in accredited laboratories using atomic absorption spectrometry (AAS) and Inductively Coupled Plasma Spectroscopy (ICP-S). Results. For the first time, data are presented on the content of biogenic metals (manganese, zinc, copper, molybdenum) in the hair of the tail of black-and-white cows and Russian White and Saanen goats in the valleys of the Lower Dniester. Conclusions. It is shown that the concentration of trace elements in the hair of farm animals reflects the relative homogeneity of the biogeochemical conditions of the Lower Dniester valley. It is established that cows and goats are characterized by a sharply differing elemental status for the studied metals estimated on the basis of an analysis of their concentrations in the hair of the tail. At the same time, the effect of hair color on the content of elements was revealed only for molybdenum in cows, and for goats there were no significant interbreed differences in metal concentrations.

In the Republic of Kazakhstan over the past decade positive changes have been observed in increasing the number of farm animals, increasing their productivity, and increasing the gross production of milk, meat and other products. At the same time the development of dairy cattle breeding is mainly due to the breeding of Black-and-White, Red Steppe, Simmental breeds and their intra-breed types as well as imported from abroad Holstein breed. The purpose of the research was to analyze ways to improve the intra-breed type Karatomar of Black-and-White breed in Northern Kazakhstan. Research work has been carried out on breeding animals such as Karatomar type cattle of Black-and-White breed in LLP “Experimental farm Zarechnoe” in the Kostanay district in the Kostanay region. The dynamics of growth and development indicators, reproductive traits of heifers of a new intra-breed type Karatomar of Black-and-White cattle have been studied. A comprehensive assessment of their economically useful traits in the first lactation, determined by the resistance of animals to climatic and forage conditions, the efficiency of breeding of animals of different genotypes has been conducted. It has been found that the replacement heifers – daughters of American breeding sires inherited precocity and showed higher growth energy after 6 months of age and continued to grow rapidly until 18 months. The advantage in metabolism was in the daughters of Holstein sires of the American selection Orbit 4078, and the increased immune status of the organism in the daughters of the sire of the domestic selection Yamal 975 as the most adapted to the conditions of Northern Kazakhstan. The best ability to increasing the milk yield, stable lactation activity, high milk productivity, gross content of dry matter and nonfat milk solids have been characterized by the daughters of sires of the American selection Orbit 4078 and Lowrider 4129. Analysis of economic indicators of milk production has been shown that from cows – daughters of sires Orbit 4078 and Lowrider 4129 for 305 days of lactation received 15,8 and 15,2 % more milk of base fat, the expenditures of EFU per 1 kg of production was lower by 10,2 and 5,9 %. A higher level of profitability has been observed in the group of daughters of the sires Orbit 4078 – 35,5 % and Lowrider 4129 – 33,1 %, which was 8,5 and 10,8 % higher than in the group of daughters of the sire Yamal 975.

In order to fi ll the existing protein defi ciency in the rations of farm animals in particular dairy cows it is necessary to input feed lupins as widely as possible in crop rotations. Lupin is a very versatile forage crop it can be used in feed as herbage, in the form of haylage, silage, in compound feed as a protein additive, as well as a green manure crop to increase soil fertility. Questions of protein nutrition should be to be quickly resolved, both in the production of protein and in its standardized rational use. Unbalanced protein rations increase feed consumption per unit of production, thereby increasing its prime cost. In the world soya is generally recognized as a protein feed, but in the Kaliningrad region as in most of regions in our country, it does not maturate being a heat-loving crop. Under these environments the inclusion of extruded lupine grain in the composition of energy-protein concentrates for the production of compound feed has become an alternative to replacing expensive soya. The researches have been carried out it the cattle farm of LLC “Temp” in the Guryevsky area in the Kaliningrad region (March-May 2019) on feeding lactating cows energy-protein concentrate from extruded grain of narrow-leaved lupine, fl ax, triticale, subjected to heat treatment on a press extruder. For this purpose two groups of lactating cows of Black-and-White breed (control and experimental) have been formed using the method of pairs of analogs per 11 heads in each. Cows of the control group have received the main ration of the farm, and cows of the experimental group in addition to the main ration have received compound feed with extruded energy-protein concentrate based on lupine. As a result of research, the positive infl uence of energy-protein concentrate based on lupine in compound feed on the dairy productivity of cows has been established. Recipes of concentrate and compound feed with concentrate for lactating cows, the volume of inclusion of components in the concentrate and in the compound feed have been calculated. During the experiment, the milk yield in the experimental group of cows has increased by 62,4 kg or 8,0 %, than in the control group. From the cows of the experimental group the conditional profi t has been received in the amount of 1684,8 rubles per head.

The aim of this study was to provide, for the first time, data on the concentration of potentially toxic elements (PTEs) in soils and bulbs of elephant garlic (Allium ampeloprasum L.) cultivated in Valdichiana, a traditional agricultural area of Tuscany, Italy. Bulbs of elephant garlic and soil samples were collected in four cultivation fields and analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) to determine the concentrations of As, Cd, Co, Cr, Cu, Ni, Pb, Sb, Tl, U, V, Zn. The concentrations of these PTEs in bulbs and cultivation soils were used to calculate geochemical, ecological and health risk indices. The results of this study suggest that, although bulbs of elephant garlic from the Valdichiana area may present slightly high concentrations of Cd, Ni and Pb, the associated health risk based on the daily intake is absolutely negligible. Cultivation soils had somewhat high Cu concentrations probably due to the diffuse use of Cu-based products in agriculture, but showed overall a very low ecological risk.

BackgroundMost intracranial stents contain nickel alloy, and nickel allergy or hypersensitivity is common. Neurological injury following endovascular treatment with a nickel containing intracranial stent has been reported in patients with purported nickel allergy, but it is unclear whether these reactions represent true nickel hypersensitivity. We quantified nickel release from commonly used intracranial stents to investigate whether such stents should be avoided in patients with nickel allergy.MethodsWe examined nickel release from seven commonly used intracranial stents: Enterprise, LVIS Jr, Neuroform, Wingspan, Zilver, Pipeline Flex Embolization Device, and Surpass Evolve. We incubated each stent in human plasma-like media for 30 days. Dimethylglyoxime (DMG) spot testing was performed on each stent to detect released nickel at 0 and 30 days. Inductively coupled plasma–optical emission spectroscopy (ICP-OES) was then used to quantify the nickel concentration of the media at 30 days. Nickel currency and nickel standard for atomic absorption spectrometry were used as positive controls.ResultsDMG spot tests indicated nickel release only from nickel currency at 0 and 30 days of incubation. No nickel release was detected from any stent at 30 days using ICP-OES.ConclusionsNickel release from commonly used intracranial stents is negligible. These results suggest that previously reported hypersensitivity to these stents may be misattributed to nickel allergy, and that patients with nickel allergy may be safely treated with select nickel-containing stents.
