Abstract

Present paper shows the results of a long time experiment in sows fedwith different protein levels. In these investigations 130 sows housed under practical production conditions were used for a period of fourreproduction cycles. There were three treatments: Treatment I: one diet during whole reproduction cycle - high oversupply of protein and energy (one-phasic feeding) Treatment II: two different diets in pregnancy and a third one in lactation usually in practice; oversupply of protein in pregnancy (three-phasic feeding) Treatment III: three-phasic feeding, supply with protein and energy adequate to requirements in pregnancy and a protein reduced, amino acid supplemented diet in lactation (supplemented amino acids: L-lysine, DL-methionine and L-threonine) Reproduction performance, persistence, development of body weight and N excretion of the sows were investigated. No negative effect of treatment III could be detected. In the long run a positive effect on breedperformance was established. N excretion was over one third lower compared to treatment II. Treatment I influenced persistence negative. These sows exhibited a higher body weight gain and higher body weight dynamics caused by energy oversupply. From third farrow a greater numberof difficulties in farrow, still-born piglets and piglets squeezed todeath, sows with MMA-syndrome and sows with hurts of extremities weredetected. These are reasons for a short utility duration of the sows and a low breeding performance. In the fourth reproduction cycle sows of treatment I brought up 1.1 piglet more compared to sows of treatment III. This effect was significantly.
