and reproduction, says Ostrenko. Animals in four experimen- tal groups were fed daily with ascorbate lithium in powder form (see Table 1). Each group contained ten two-month old pigs of the British Landrace breed at an industrial farm in Rus- sia’s Belgorod region. Weighing was done before the introduc- tion of the additive, on the fourth month and before slaugh- ter. In addition, before the animals participated in the experiment and on the 180th day of the experiment, blood samples were taken. As a result of the impact of technological stressors, an increase in catecholamines, haemoglobin, eryth- rocytes and lymphocytes in the blood occurs in fattening ani- mals, which indicates the mobilisation of energy resources as well as the bactericidal and phagocytic activity of cellular ele- ments, the scientists report. Basing on their findings, researchers claim that lithium ascor- bate has some adaptogenic and stress protective properties and prevents a sharp increase in adrenaline and norepineph- rine levels in pigs. The additive has also been found to main- tain concentrations of cortisol, which is commonly believed to be the main stress factor in the bloodstream at a physiological level. The blood samples collected during the trial showed that by acting on protein and lipid metabolism, lithium ascorbate activates functions associated with the participation of α- and β-globulins in the transport of lipids, steroid hormones, and in the performance of γ-globulin protective functions. Lithium ascorbate has a positively effect on the lipid-cholesterol me- tabolism and antioxidant status and, as a result, contributes to higher live weights and better meat quality, the scientists con- cluded. In addition, in earlier research it was found that lithium ascorbate has a positive impact on sows, increasing the num- ber of offspring and enhancing the nutritional properties of milk during lactation, Ostrenko says.
Commercial use in the pipeline Feed additives based on lithium ascorbate are not being used in pig farming anywhere else in the world, Ostrenko says. The scientific group has already filed an application to take out a patent on the new additive, which means that commercial use of the new additive is to be expected. Some Russian pig pro- ducers have already expressed an interest in the new pig anti- depressant since it is believed that the new drug could make them more competitive pricewise, including in export markets.
