Abstract

The article examines the influence of feeding conditions of suckling piglets on the indicators of their protein, lipid, carbohydrate, mineral and vitamin metabolism. The purpose of the scientific and economic experiment was to establish the effect of the suckling regime of piglets on their metabolic rates. For this purpose, 4 groups of sows with three heads in each were formed on the principle of analogues. Five days after farrowing, 10 piglets were left in each nest during weaning. This took into account their live weight at birth and at 5 days of age. The sows of the control group fed 10 piglets, while the sows of the 2nd, 3rd and 4th groups fed 20, 30 and 40 piglets, respectively.

After the piglets reached 5 days of age, the suckling regime, except for the animals of the control group, was artificially regulated. To do this, sows were expelled for the time provided by the scheme of the experiment on the playground, where they received according to the norms of feeding standard feed.

The suckling piglets received cow's milk and weaning from a place where they were fed, and had free access to feed according to age.

Studies have shown that reducing the amount of suckling piglets to 8-24 times a day compared to piglets that had free access to the sow is accompanied by an increase in blood total protein, non-esterified fatty acids, calcium, phosphorus, carotene and vitamin A. The level of creatine kinase and lipase in the blood of suckling piglets decreased to 8-24 times during the day. It was found that different subsystem regimes and the associated unequal feed intake of piglets, which regulated the time between pods, led to a decrease in their blood total lipids and phospholipids, immunoglobulins, hemoglobin and alkaline blood capacity compared to piglets that had free access. to the sow during the weaning period.
