Effects of potassium diformate (Formi® LHS) in combination with different grains and energy densities in the feed on growth performance of weaned piglets

摘要: Summary To examine the effects of Formi®LHS (Norsk Hydro a.s., Oslo, Norway)on growth and health performance weaned piglets fed on diets at different energy levels, three experiments were conducted. Experiment I comprised 48 crossbred (German Landrace × Pietrain) (7 kg live weight) in single rearing battery cages a metabolism barn, experiment. II with 72 Landrace, 9 kg groups animals kept flat-deck boxes an experimental farm experiment III 96 (8 kg again cages. In equally allotted to four treatment receiving complete feed (type starter feed) containing either 13 MJ ME/kg or 14 MJ ME/kg without supplementation 1.8% Formi®LHS. based barley, wheat, corn, mixture them prepared applied resulting eight treatments. Feed intake, weight gains, conversion (kg feed/kg gain), occurrence diarrhoea recorded. low-energy level improved final weights by 5 12%, respectively, daily gains 8 18%, 6% each, intake being higher 1 8%, respectively. With up 10%, 14%, 11% than unsupplemented group, but particularly group feeding, these data lower those Formi®LHS-supplemented group. did not improve feed. there no differences consumption efficiency between grains. increased all types 14 9%, significantly only combination wheat. was barley–wheat–corn diet (6, 4 7%, respectively) corn diet.
