Optimization of microelements in the composition of protein-vitamin-mineral additives for pigs growing

Abstract

The results of studies to determine the optimal level of input of a complex of macronutrients in protein-vitamin-mineral supplements are given, their influence on digestibility, the use of feed nutrients, hematological parameters, growth and development of young pigs are studied. Feeding in the composition of grain-cereal rations of 12.5% protein-vitamin-mineral supplements with elevated levels of Fe, Cu, Zn, Mn, Co, J, Se contributes to an increase in pigs by 5.5-8.5% of daily gains, by 8-12 days of early maturity, by 0.28-3.35% slaughter yield, by 12.1-19.5% meat ratio. Bringing microelements to the optimum level in protein-vitamin-mineral supplements composition contributes to a significant increase in the digestibility of organic matter and raw fat. Reducing the level of trace elements by 30% hinders the process of digestion of feed. The use of 12.5% protein-vitamin-mineral supplements with a high content of trace elements in grain-cereal rations of pigs has a significant effect on the degree of utilization of nitrogen, calcium, phosphorus, iron, copper, zinc, manganese. When protein-vitamin-mineral supplements are fed with an optimal level of trace elements in the composition of diets of young pigs, it contributes to an increase in the number of erythrocytes, hemoglobin, total protein and its fractions. A 30% increase in the level of trace elements in protein-vitamin-mineral supplements provides for obtaining high-energy meat with a high content of dry matter, protein and fat. The inclusion in the composition of grain-cereal rations of protein-vitamin-mineral supplements with the optimal level of trace elements helps to reduce the cost of feed by 5.2-7.8%, to obtain 3.8 kg of additional growth.

Influence of organic and non-organic microelements on productivity and metabolic processes in growing young pigs

“…This form improves the absorption of trace elements, as it reduces the degree of their connection with nutrients that can form insoluble compounds with trace elements found in the form of free cations. Guryanov et al (2019) reported that during the feeding by grain-grain diets, 12.5% of protein-vitamin-mineral additive with increased levels of Fe, Cu, Zn, Mn, Co, I, and Se contributed to 5.5-8.5% increase in average daily gain. Salautin et al 2020found that the addition of 10% complex of trace elements to the feed of growing pigs due to L-aspartic acid (Zn, Cu, Fe, Mn, and Co) from the norm increases the activity of most metabolic processes in the body and determines the most pronounced positive effect of feed assimilation and productive qualities.…”

“…Viktorov (2007), the introduction of cobalt, zinc, and manganese contributed to the increase in body weight by 8.2% and in average daily gain by 10.9%. Feeding of sows in the suckling period by a mixture of cobalt, zinc, copper, and iron salts contributed to better absorption of feed nitrogen, more intensive growth and development of pigs (Guryanov et al, 2019). Recent results show that trace elements have a strong effect on energy metabolism, pigs' productivity and improve the use of feed nutrients.…”

Effect of balanced mineral supplements on milk productivity of cows

“…Thus, in the available literature, there are reports of an increase in milk productivity [4][5][6] and milk quality [4; 6; 7] in cows, and an improvement in reproductive function in bulls [8]. In addition to milk productivity, there is also an improvement in the growth of calves [9], pigs [10][11][12], broiler chickens [13; 14] and rabbits [15] due to the use of chelated forms of trace elements in their feed. The reason for the growing interest of the scientific community in organic compounds is the high degree of their assimilation by the body, which provides animals with the necessary amount of trace elements and reduces the negative impact of their faeces and urine on the environment [3].…”
