Feeding level of repair piglets and subsequent productivity of sows in conditions of steppe zone

Abstract

The purpose. To study productivity of standard and author’s balancing feed additives at growing pigs.Methods. Groups-analogs (control and experimental), zootechnical, statistical, morphological, economic. Results. Expediency is proved of feeding repair piglets and sows with author’s feed additives at their add-on to feed compounds twice less, than standard. Conclusions. The recommended feed additives improve utilization of nutritive matters of a ration on synthesis of products due to rising its digesting. That favours to increase of daily average incremental values of repair piglets, decrease of expenditures of feedstuffs for 1 kg of mass increase and augmentation of productivity of sows.
