THE EFFECTS OF COMPLETE MIXTURES FROM VARIOUS DOMESTIC PRODUCERS IN NUTRITION OF GROWING PIGS

The effects of nutrition using complete mixtures from five producers on production performance, digestibility of nutrients and cost of
1 kilogram of gain in nutrition of growing pigs were investigated. Obtained results showed that: the best pig production is realized using control mixture A, slightly lower results with diet B, followed by mixtures C, D and E. Degree of utilization of dry, organic matter and protein was best in diets A and B, and slightly lower in remaining C, D and E diets. The cheapest gain was realized by using mixtures A and C, followed by mixture B, and the least favourable cost of gain was recorded in pigs fed diets D and E, without any established differences between them. In general, obtained results showed that by using the mixtures from various manufacturers certain differences in production performance were established, also in the degree of utilization of nutrients and cost of kilogram of gain in growing pigs.
