“…The live weight of broiler chickens on day 8 in all three groups was almost the same at 230.2-239.5 g. Over the next week, after the introduction of the additives under study into the diet, the poultry began to grow more intensively and in the second group the live weight of chickens was 97% higher (at p<0.001), in the third group -by 10.5%. The absolute increase in live weight during the period of feeding the starter feed (days [3][4][5][6][7][8][9][10][11][12][13][14][15] was 11.7% higher in the second group (p<0.01), and 12.7% higher in the third group (p<0.001) compared to the data in the control group. The relative increase in live weight, which characterises the growth rate, during this period of poultry rearing with the introduction of the additive "Kronocid-L" to the diet is 3.3 p.p.…”
Demand for chicken meat has been growing in recent years, requiring prominent production levels and efficient feed conversion. The purpose of this study was to determine the productivity, preservation, and slaughter performance of broiler chickens, feed conversion on the background of feeding with additives with chelated forms of trace minerals. Poultry growth intensity was determined according to zootechnical methods, slaughter indicators – according to morphological methods, and statistical analysis of the results was used. By the end of the rearing period, the live weight of broiler chickens in the groups where the dietary supplement with chelated trace minerals (second group) and copper chelate complex (third group) was significantly higher than in the control group – by 6.9% and 13.8%, and the relative increase was 4.5 percentage points and 8.5 percentage points, respectively. The growth rate of broilers in terms of average daily weight gain is higher in these groups by 6.8% and 14.2%, respectively. The safety of poultry in the experimental groups is 4% better than in the control group. The feed conversion of a diet with chelated trace element additives is higher. Feed consumption in the experimental groups was reduced by 2.8% when feeding the selected additive and by 9.7% when feeding the copper chelate complex. The results of balance studies revealed an increase in the digestibility of nutrients in the diet of broiler chickens. Additives with micronutrient chelates are effective in increasing slaughter yield, meatiness of the thighs and shins, and pectoral muscles by 5.3-6.2 percentage points. The broilers of the experimental groups had a higher meatiness of the thighs and shins. The highest growth rate was found in broilers fed a copper chelate complex in their diet. The lower feed conversion in the control group is due to the lower body weight of these chickens. Based on the research data obtained, the possibility of effective introduction of additives with chelated microminerals into the diet of broiler chickens was established, which helped to increase the growth rate and meat yield. The results can be used in farm poultry farms to produce more products and reduce the cost of chicken production

“…Considering its dominant degree of oxidation, Zinc (Zn) (Gomathi et al, 2018) is an integral part of several biochemical pathways as a catalytic or regulatory co-factor. It also has a structural role in many other functional proteins (Fotina et al, 2021). (Mn) plays an essential role in various biological processes, being a significant co-factor of superoxide dismutase, transferase, hydrolase, and lyase (Bai et al, 2014;Xiao et al, 2014).…”

“…In research, scientists have found that the use of chelated compounds of Zinc, Copper, and Manganese, as a feed additive, stimulates an increase in the overall natural resistance of broilers, accompanied by an increase of 7.4 % bactericidal activity, 8.3 % phagocytic activity, and 6,6 % of lysozyme activity. In this regard, chelated elements should be used in industrial poultry, as they can be used as a potent immunostimulant that provides good quality products without antibiotics (Fotina et al, 2021).…”

“…Experiments have shown that using chelated compounds of Zinc, Copper, and Manganese increased the hatchability of chickens by 1.92 %, increased egg production by 5.8 %, and reduced feed conversion by almost 6 %. An increase in the ash level in the dry matter of day-old chicken bones by 4.3 % indicates an improvement in the skeletal structure of the offspring of the group where chelated compounds were used (Fotina et al, 2021).…”
The paper considers the use of chelated forms of micronutrients for feeding broilers. The study aims to investigate the chemical composition of broiler meat in the case of broiler chickens of Cobb-500 cross, provided Zn, Cu, and Mn chelated forms are supplied to the diet. Experimental studies were conducted in 2020 on broiler chickens of Cobb-500 cross. Two groups of 20 birds were formed to study the chemical composition of poultry meat. The birds of the control group received an essential diet supplied with sulfates of Zn, Cu, and Mn. The birds of the experimental group received a diet enriched with chelated compounds of Zn, Cu, and Mn. The study has shown that introducing Zn, Cu, and Mn chelated compounds into the diet of broiler chickens has no adverse effect on the chemical composition of meat. It has also been determined that the meat of broilers eating feed supplied with chelated micronutrients contains significantly less cholesterin but more Ca, Zn, Cu, and Mn, and several essential amino acids. These indicators prove an increase in the health benefits of chicken meat.
“…Zinc is found in several metalloenzymes such as RNA polymerase, carbonic anhydrase, and several others that affect nutrient metabolism. Zinc absorption mainly occurs in the small intestine [6]. The Zn requirement for a growing heifer is 200-300 mg and 22.8 mg/kg of ration.…”
Breeding young cattle is important, especially during the transition period from dairy feeding to concentrated dry feed. The paper presents the results of the use of biogenic metal nicotinates for weaning calves to improve metabolism in animals.
The aim of research. To investigate the effect of biogenic metal nicotinates: Zn, Cu, Fe, Co, Mn on the biochemical parameters of blood in calves after weaning.
Materials and methods. The study was carried out during 2021 in the conditions of LLC "Agrofirma Lan", Sumy region, Sumy district, Kindrativka, Ukraine for breeding young cattle. The calves of the experimental group were given compound feed and a premix of nicotinates of biogenic metals: Zn, Cu, Fe, Co, Mn, manufactured by PPronos Agro" (1 g per 1 kg of feed). In the control group, combined feed and a premix with metal sulfates were used for 30 days.
Results. An increase in the level of total protein in the body of calves of the experimental groups was established by 16.12 % in comparison with the control (p≤0.05). Also, in experimental animals, the activity of the enzymes alanine aminotransferase and aspartate aminotransferase was higher than the physiological norm, which shows an insignificant effect of nicotinates of biogenic metals on internal organs and systems. In the experimental group of calves, the level of magnesium was probably higher by 52.38 % and potassium – by 14.94 % compared to the control group (p≤0.05). It was found that the animals of the experimental groups probably had more zinc by 34.96 %; copper – by 35.72 %; iron – by 92.29 %; manganese – by 41.13 %; selenium – by 3.22 % and cobalt – by 98.33 % compared to the control (p≤0.05).
Conclusions. The positive effect of the use of biogenic metal nicotinates on the metabolism of calves at weaning has been proven. It was found that the level of total protein in the body of calves of the experimental groups was probably higher by 16.12 %, magnesium - by 52.38 %; potassium - by 14.94 %. When determining the content of inorganic substances, it was found that the animals of the experimental groups probably had more zinc by 34.96 %; copper – by 35.72 %; iron – by 92.29 %; manganese – by 41.13 %; selenium – by 3.22 % and cobalt – by 98.33 % compared to the control (p≤0.05)
