The effect of different pre-mixtures in nutrition of fatteners

Abstract

We have been witnesses to import of numerous premixes produced by various producers and of different quality in regard to concentration of ingredients which are their main components. In our previous studies (Živković et al., 2010) we obtained results confirming that in use of domestic premix more economically efficient production is realized in nutrition of sows and piglets, so this research was carried out with objective to verify the effects of several different imported premixes and those produced according to domestic concept, in nutrition of growing-fattening pigs. Research was performed on private farm in the vicinity of Šabac in Serbia. Nutrition of fattening pigs using mixture which contained adequate premix of domestic production improved the growth rate by 7.6% without any significant difference in food conversion. Cost of feed when domestic premixes were used in nutrition of fattening pigs was by 4.1% lower and value of realized pigs by approx. 4.51% more favourable when domestic premixes were used in nutrition of investigated animals. Dressing percentage of pigs on domestic premixes was higher by 2.0%, and there was no difference in meatiness between compared groups of animals in the experiment. In general, obtained results showed that use of both types of compared premixes can be recommended, but it is more economically efficient to use domestic premixes in nutrition of fattening pigs.

Poslednjih deset godina svedoci smo uvoza mnogobrojnih premiksa raznih proizvođača različitog kvaliteta u pogledu koncentracija ingredijenata koji ulaze u njihov sastav. Relativno je malo podataka (Živković et al., 2010) o efektima njihove nutritivne vrednosti kod svinja, zbog čega su ova ispitivanja i izvedena sa ciljem da se provere efekti palete premiksa iz uvoza i onih proizvedenih po domaćem konceptu čiji je idejni tvorac prvoimenovani autor ovoga rada, u ishrani svinja u tovu. Istraživanja su izvedena na privatnoj farmi svinja u Platičevu u okolini Šapca u Srbiji. Dobijeni rezultati su pokazali da se ishranom tovljenika smešama sa odgovarajućim koncentracijama domaćeg premiksa prirast poboljšava za 7,6% uz skoro identičnu konverziju hrane. Cena hrane korišćenjem domaćeg premiksa u ishrani je bila za 4,51% povoljnija te je cena ostvarenog prirasta bila za 4,51% povoljnija od onoga ostvarenog ishranom smešom istog sastava uz korišćenje premiksa iz uvoza. Na liniji klanja pokazalo se da nije bilo bitne razlike u mesnatosti u polutkama, ali je grupa na obroku sa domaćim premiksom iskazala za 2,0% povoljniji randman. U celini dobijeni rezultati su pokazali da se preporučuje korišćenje obeju vrsta upoređivanih premiksa, ali je ekonomičnije koristiti domaće premikse u ishrani svinja u tovu.
