Effect of feeding sows PVMA Intermiks on digestibility and metabolism of pigs

Abstract

Pork production in modern conditions associated with the use of feed and dietary supplements as part of diets, because without them to provide animals essential nutrients almost impossible. Especially for little Ingredient grain rations. Therefore have resorted to creating new PVMA. These concerns and PVMA Intermiks PS – 7.5% and Intermiks LS – 20% – according to gestation and lactating sows. So were conducting research on the influence of feeding PVMA Intermiks sows in different periods of the reproductive cycle of feed digestibility and metabolism of nitrogen, calcium and phosphorus in their piglets weaned at 28 days age. Research groups conducting two–analogues pigs of large white breed balance method, under which the pigs were kept in individual cages and accounted for eight days consumed feed, feces and urine color. The live weight per head was 9 kg. Sows experimental group during 85 days gestating 7.5% by weight was replaced grain mix PVMA Intermiks PS, and next to farrowing and weaning piglets at 28 days age, replaced 20% concentrated feed on PVMA Intermiks LS. Sows in the control group were kept in complete feed appropriate. After all born piglets up to 14 days eating a special supplement Intermiks SP «Bambino» – 25%, and from 14 to 28 days – Intermiks SP – 25%. Studies have shown that feeding sows PVMA Intermiks increases performance polycarpous 10.8% weight in the pig–breeding nests by 25.3% and 13.3% macrocarpa. The weight of a piglet at birth the control and the experimental groups was 1.05 and 1.19 kg and at weaning at 28 days of life – 8.52 and 9,1 kg. Piglets from sows receiving PVMA Intermiks had higher levels of digestibility of crude oil (3.3%) and fiber (to 5.37%). No significant difference was obtained for the digestibility of dry, organic matter and protein compared to piglets from sows with complete feed in the diet. In the experimental pigs tends to increase the number of nitrogen retained in the body (14.5 %) and from the accepted and digested (by 4.4 and 6.0%). Terms feeding lactating sows gestation and no likely impact on calcium and phosphorus in pigs weaned at 28 days age.
