Effects of enzyme mixture addition and nutrition pattern on production traits of weaned piglets

Abstract

With the aim to investigate the effect of adding enzyme mixture in the diet of weaned piglets and the nutrition pattern on their productive traits, the trial was performed with 56 piglets classified into 4 groups. The concentration of added enzymes was 0.1%. The body weight gain of piglets fed with enzyme mixture addition in diets with limited or ad libitum feeding was increased by 6.58 and 7.21%, respectively. The intake of feed for a kg of body weight gain in the groups III and IV was smaller by 4.35 and 7.83%, respectively, in relation to the control. Piglets fed ad libitum without addition of enzyme mixture had a body weight gain greater by 3.76% and a feed conversion ratio better by 3.48 than the group I. The highest stimulatory effect was observed in the first two weeks after weaning.

U cilju ispitivanja efekata dodavanja enzimske smeše u obrocima odlučene prasadi i načina ishrane na njihove proizvodne sposobnosti, izveden je eksperiment sa ukupno 56 prasadi podeljenih u 4 grupe. U hranu prasadi dodavana je enzimska smeša (amilaze, celulaze i proteaze) u koncentraciji od 0,1%. Dodatak enzimske smeše u kombinaciji sa ishranom po volji ili ograničenim načinom ishrane povećalo je dnevni prirast za 6,58 i 7,21% i poboljšao efikasnost iskorišćavanja hrane za 4,35, odnosno za 7,83%. Grupa prasadi hranjena po volji bez dodatka enzimske smeše imala je za 3,76% veći dnevni prirast i za 3,48% bolju konverziju hrane u poređenju sa I grupom. Posebno visok efekat ostvaren je u prvih 14 dana nakon zalučenja.
