Influence of granulated potassium carbonate on productivity and meat quality of pigs

Potassium is the 3rd most important element in the body. It should be ingested daily with feed, as it remains in the body for a short time, and the needs of animals for potassium are very important, since potassium is a cation donor. The article reflects the results of using potassium carbonate in feeding pigs during fattening. Experiments and production tests conducted in the stud farm named after. Lenin of Tambov region. Analysis of the productivity of pigs indicates a positive effect of introduction to the diet of animals of potassium carbonate. Inclusion of 2 and 4 kg of potassium carbonate per 1 ton of feed had a positive effect on productivity, physiological processes, the clinical state of animals, digestion, the development of internal organs and the meat qualities of fattening young pigs. The average daily weight gain in pigs during fattening increased by 22 and 33 g, or by 3.0 and 4.7%. This indicates a better absorption of food in animals that received carbonate in their potassium intake. Indicators of meat productivity in pigs fed in rations of potassium carbonate were higher in slaughter output of carcasses by 0.8 and 1.2% and in meat quality indicators. The lard thickness at the 6-7 thoracic vertebra level was less in the experimental groups receiving the feed additive in both diets by 1.0 and 0.5 mm, and the area of the “muscular eye” increased, respectively, by 0.8 and 1.5 cm². Analysis of the chemical composition of the meat showed a high nutritional value from experimental animals. The meat contained 4.3-4.1% fat, 21.9-22.2% protein. These indicators correspond to high commodity and taste of meat. Calculations of the economic efficiency of pork production using potassium carbonate show that an additional net income of 194.4 and 271.8 rubles was received for 1 head with a live weight of62.7-63.6 to 109.8-111.6 kg experienced groups of fattened pigs.
