Balance of mineral substances in the body of new zealand breed kings when feeding vitamin-mineral supplements
It is important to balance the diets of rabbits with minerals and vitamins. These compounds are very important for the body of rabbits and take an active part in metabolic processes. Animal health, reproduction, preservation and productivity depend on them. A very important issue is the consumption of minerals by the animal, their assimilation in the body and excretion from it. The assimilation of mineral elements is influenced by security, their content in the feed, the nature of the compounds in which these elements are, the ratio between the individual mineral elements and their groups, vitamins, and so on. The author theoretically substantiated and practically proved the effectiveness of the use of vitamin and mineral supplement "Tekro" for rabbits of the New Zealand breed. According to the quantitative characteristics of the mineral elements required for animals, Calcium ranks first and is especially needed at the time of skeletal formation. The introduction into the diet of rabbits of the 3rd and 4th experimental groups of vitamin and mineral supplement "Tekro" showed increased absorption of calcium in their body. Thus, according to the indicator of assimilated Calcium, rabbits of the 3rd and 4th experimental groups predominated in control animals, respectively, by 4.1 and 7.8%. (p≤0.05). Phosphorus is also one of the main and very important trace elements and along with Calcium is involved in all metabolic processes in the body, being part of various organic compounds, proteins, phospholipids, nucleic acids. Additional feeding of vitamin and mineral supplements to experimental rabbits provided an increase in the rate of assimilated Phosphorus in the body of rabbits 2-, 3- and 4th experimental groups, in which they exceeded control counterparts by 5.4%, 6.7% and 4.2%. Feeding rabbits of New Zealand breed vitamin-mineral supplement "Tekro" in the amount of 3.5% in the 3rd experimental group also helped to increase the intensity of their growth for 45 days, provided the opportunity for better transformation of nutrients from feed into products, which was confirmed by analysis of manometric parameters and recorded the highest percentage of slaughter yield at 90 days of age, which was 8.89% higher than the control group. Also in rabbits of the 3rd experimental group at the age of 90 days higher activity of glutathione peroxidase in blood plasma was observed, which was 11.2% (p≤0.05) higher in comparison with rabbits of the control group.
