Biochemical processes in piglets that have been receiving a new pre-starter compound feed

Abstract

The feed value of modern balancing concentrates intended for compound feed to early weaned piglets is based on a combination of energy and easily digestible protein: protein-soya concentrate, potato protein, high-quality fi sh meal and dairy feeds. A protein-vitamin-mineral concentrate containing vegetable protein intended for balancing compound feed for early weaned piglets has been described in the article. It provides for the use of a component from full-fat fl axseeds, which contains polyunsaturated linolenic acid. The composition of the concentrate included pulses and oilseeds, processed by special technology for the removal of anti-nutritional substances. Data on the infl uence of pre-starter compound feed containing the developed concentrate on the body and productivity of suckling pigs have been presented. The animals from the experimental group had more intensive metabolism. The total protein content in the blood serum was in the range of 65,53–65,73 g/l, and the ratio of albumins to globulins (coeffi cient A/G) was optimal – 1,55 and 1,67. The presence of the large amount of urea and glucose in the blood (3,05–3,72 and 6,60–5,80 mmol/l, respectively) indicated that crossbred piglets had intensive synthetic processes associated with the growth of muscle tissue and internal organs. The redox processes have been intensive, which was indicated by the high content of hemoglobin in the blood at the level of 119,7–120,6 g/l and red blood cells (4,32–4,42×1012/l). The ratio of calcium to phosphorus was optimal that indicating the balanced mineral metabolism. The average daily gains in live weight of experimental animals were almost identical at the level of 253–254 g. The results indicate that the new balancing concentrate and pre-starter compound feed containing it had the favorable eff ect on the metabolism in the body of suckling piglets.
