Efficiency of using new lecithin-containing feed additive when growing piglets

Purpose. Evaluation of the effectiveness of using new lecithin-containing feed additive when growing piglets. Materials and Methods. The object of the research was piglets of the large white breed and the new feed additive Lecitomiks. Zootechnical, clinical, physicochemical and biochemical research methods that do not require validation were used in the research work. Results. Weaned piglets of experimental group 1 (feed additive dose – 250 g / t of feed) exceeded the live weight of control analogues by 1.18 kg or 6.40%, the average daily gain by 0.04 kg or 10.81%, the absolute gain by 1.14 kg or 10.20% (P≥0.95). The piglets of experimental group 2 (feed additive dose – 500 g / t of feed) exceeded the live weight of control animals by 1.96 kg or 10.61% (P≥0.99), the average daily gain by 0.07 kg or 18.92% (P≥0.95), the absolute gain by 1.97 kg or 17.62% (P≥0.95). Hemoglobin was higher by 2.50 g / l or 2.51% (P≥0.95) in the blood of piglets of experimental group 1, erythrocytes by 0.14 × 1012 / l or 2.23% (P≥0.95) than in animals of the control group. In experimental group 2, the hemoglobin level was higher by 3.60 g / l (3.61%) (P≥0.95), the number of red blood cells was higher by 0.17×1012 / l or 2.70% (P≥0.95). When conducting a biochemical study, a significant increase in the total protein content of the blood serum of experimental piglets of group 1 was found in relation to the control ones by 3.51 g / l or 5.03% (P≥0.95), group 2 – by 4.33 g / l or 6.20% (P≤0.95). In experimental group 1, the digestibility of dry matter compared to the control group was higher by 4.20% (P≥0.95), organic matter – by 2.40% (P≥0.95), crude protein – by 2.30%, crude fat – by 6.10% (P≥0.99), crude fiber – by 4.20% and nitrogen-free extractives – by 2.40% (P≥0.95); in experimental group 2 – by 4.80 (P≥0.95); 3.00 (P≥0.99); 2.80 (P≥0.95); 7.20 (P≥0.999); 3.30 and 3.10% (P≥0.95) respectively. The suckling piglets of experimental group 1 (feed additive dose – 250 g / t of feed) exceeded the animals in the control group by 0.57 kg or 7.93% in live weight, in experimental group 2 (feed additive dose – 500 g / t of feed) – by 0.73 kg or 10.15% (P≥0.95). The values of the average daily and absolute increase in live weight of piglets in experimental group 1 were significantly higher than the corresponding results of control animals by 0.02 kg or 11.16% (P≥0.999) (average daily gain) and 0.53 kg or 11.18% (absolute increase) in experimental group 2, the average daily increase was also higher by 0.04 kg or 14.97% (P≥0.999), the absolute one – by 0.68 kg or 14.35%. When studying blood, piglets of experimental group 1 differed from control analogues by an increase in the amount of hemoglobin by 1.10 g / l or 1.13% (P≥0.95), erythrocytes – by 0.25 × 1012 / l or 4.22% (P≥0.95); in experimental group 2, the hemoglobin level was higher by 3.02 g / l or 3.08% (P≥0.95), the number of red blood cells was higher by 0.56 × 1012 / l or 9.46% (P≥0.95). The content of total protein in the blood serum of experimental piglets relative to the control analogues in the first experimental group was higher by 1.22 g / l or 1,46% (P≥0.95), in the second experimental group – by 1.63 g / l or 2.62% (P≥0.95). Safety of animals among experimental piglets is 1.60% (P≥0.95) higher than in the control. In experimental group 1, the digestibility of dry matter compared to the control group was higher by 3.20 (P≥0.95)%, organic matter – by 5.30% (P≥0.999), crude protein – by 4.10% (P≥0.999), crude fat – by 5.80% (P≥0.999), crude fiber – by 5.00% and nitrogen-free extractives – by 2.10%; in experimental group 2 – by 4.90 (P≥0.999); 8.40 (P≥0.999); 4.50 (P≥0.999); 8.90 (P≥0.999); 7.10 and 3.50% (P≥0.95) respectively. No side effects have been identified when using the feed additive Lecitomiks for piglets. Conclusion. Lecitomiks feed additive in the recommended dosage regimens has a beneficial effect on increasing the productive effect of feed and body weight gain in weaned and suckling piglets.
