The effects of complete mixtures from various domestic producers in nutrition of growing pigs

Abstract

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.

Ispitivani su efekti ishrane smešama od pet proizvođača na proizvodne rezultate, svarljivost hranljivih materija i cenu kilograma prirasta u ishrani svinja u porastu. Dobijeni rezultati su pokazali da se: najbolja proizvodnja kod svinja postiže ishranom kontrolnom smešom A, nešto slabiji obrokom B, pa smešama C, D i E proizvođača. Stepen iskorišćavanja suve, organske materije i proteina je bio bolji kod obroka A i B a nešto slabiji kod preostalih C, D i E obroka. Najjeftiniji prirast je ostvaren kod A i C smeša , zatim sledi kod smeše B a najnepovoljnije cenu prirasta svinje su bile na obrocima D i E između kojih nije bilo razlika. U celini dobijeni rezultati u ovom radu su pokazali da se, korišćenjem smeša različitih proizvođača u Srbiji ostvaruju razlike u proizvodnim rezultatima, stepenu iskorišćavanja hranljivih materija i ceni kilograma prirasta svinja u porastu. .
