Feeding of weaned piglets without using fish meal

The productivity of fattening pigs highly depends on composition of starter feed .Therefore, while feeding the weaned piglets, it is very important to have feed of high quality. This feed should be balanced according to all necessary feed ingredients. As well the fodder for weaned piglets must be safe and not make any harm to composition of intestine microflora. Sometimes feed is contaminated with Escherichia coli and Clostridium perfengens pathogens. Therefore it is necessary to find out such material for starter feed production, which would be safe, easy digestible and nutritive. This raw material should act positively on the intestine microflora of piglets. The aim of the work – to establish the influence of „HP 300“ soy protein concentrate for wellness of weaned piglets, for their growth, to compare efficiency of this concentrate and fish meal. Conclusions: 1. The pigs from both groups were healthy; there were no rejects during test period. Veterinary medical preparations were not used; 2. The positive effect of “HP 300” soy concentrate for weaned piglests depends on their age. During the first investigation period the overweight was higher by 6 % comparing with control group. Anyway, the differences are not statistically trustworhty. During the second investgation period the overweights were more higher. Making calculations during all experiment, the daily weight gain of piglets from II group (which got fodder with “HP 300”), was higher appr. by 18 % comparing with the piglets from control group. Again, differences are not statistically reliable; 3. Fodders with “HP 300” soy concentrate were better consumed. Taking into account both trials, during the investigation process, piglets from experimental group ate appr. 7 % and 31 % accordingly more feed per day comparing with control group; 4. Positive effect of soy concentrate “HP 300” was determined for fodder expenditure 1 kg weight gain to grow during second period. Piglets from trial group used less fodder by 4 % comparing to control group; 5. The usage of soy concentrate “HP 300” during all feeding period was more effective economically by 0,13Lt (7,0 %) comparing with fish meal
