Morpho-biochemical parameters of blood and antioxidant protection of the body of repair pigs using natural metabolites

Abstract

The authors conducted experiments to study the effect of natural metabolites fed to repair pigs in the last three months before insemination on their growth, changes in their live weight, the chemical composition of milk and the content of immunoglobulins in it, as well as morphological and biochemical blood compositions, protein, carbohydrate and lipid metabolism in pregnant and suckling sows. Four groups of repair pigs were formed for research white breed (control and three experimental) at the age of 6 months, 20 heads each, which were kept in separate machines. The control group received the basic diet, without additives. The pigs of the experimental groups were fed natural metabolites from the sixth to the ninth month inclusive. The animals of the I experimental group were fed organic selenium (Selenium) as part of the compound feed – 0.3 kg / t of feed, II experimental group – succinic acid at the rate of 20 mg / kg of live weight (frequency of 10 days), III experimental group - Carolin preparation (beta-carotene oil solution) – 15 ml / head per day. At the ages of 6.5 and 9 months, 5 pigs from each group had blood taken from the ear vein in the morning before feeding for research. The object of research was repair pigs of large white breed and Krasnodar meat type. Feeding of animals both in this experiment and subsequent ones was carried out taking into account detailed feeding standards. The composition and nutritional value of the diets were calculated using the «Kormoptimaexpert» program.
