Influence of the new pre-starter feed on metabolism and immune status of piglets

Abstract

A protein-vitamin-mineral concentrate (PVMC) containing plant protein has been developed for balancing compound feed for early weaned piglets. It uses a component from complete-fat fl axseeds, which contains polyunsaturated linolenic acid. The composition of the concentrate includes legumes, processed by special technology for the removal of anti-nutritional substances. Data on the effect of pre-starter compound feed containing the developed concentrate on the metabolism of nitrogenous substances in the body and some indicators of the neurohumoral link of the immunity of suckling pigs have been presented in the article. The animals had an intensive metabolism of nitrogenous substances. 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 (coefficient A/G) was optimal – 1,55–1,67. The presence of a large amount of urea and glucose in the blood (3,05–3,72 and 6,60–5,80 mmol/l) has indicated that crossbred piglets had intensive synthetic processes associated with their growth. They contributed to the accumulation of M and G classes of immunoglobulins in the blood. The IgG content in the blood was 0,58–1,36 mg/ml, and IgM was 0,71–0,80 mg/ml. In terms of the amount of immunoglobulin G, the experimental group of piglets significantly exceeded the control group. Intestinal microbiocenosis in animals that have been received the new pre-starter compound feed was optimal. It has been dominated by positive microfloralactic acid and bifidum-bacteria, which inhibited the growth of pathogenic microflora, increasing the resistance of the piglets of the experimental group. Average daily gains in body weight were almost the same in both groups at the level of 253–254 g. Research results indicate that the new concentrate and pre-starter compound feed containing it had had the favorable effect on nitrogen metabolism and the immune status of the body of suckling piglets.
