Use of oilseed rape meal in livestock diet

Abstract

The extraction of oil from oilseed rape seeds leaves behind the so-called meal, which has about 40% crude protein and is used as animal feed. A trial with oilseed rape lasting from 1998 till 2000 was established at the Rimski Šančevi Experiment Field of the Institute of Field and Vegetable Crops in Novi Sad. The highest average seed yield per plant (11,5 g) and the highest protein content (21,9 %) was observed in Novi Sad cultivar Sremica, meaning that the extraction of oil from its seed can leave behind the highest yield of protein-enriched meal. After their plant height, number of lateral branches, leaf number and stem thickness it was concluded that Banaćanka Sremica, Falcon, Duna and Casino have high potential for green forage yield and that they can be utilized for direct cattle feeding as a fresh forage as well as a gene donors in breeding for higher forage yield.

Nakon ekstrakcije ulja iz semena uljane repice ostaje sačma koja je zbog visokog sadržaja proteina (oko 40 %) pogodna za ishranu stoke. U periodu od 1998. do 2000. godine, na oglednom polju Naučnog instituta za ratarstvo i povrtarstvo iz Novog Sada izvedena su sortna ispitivanja 10 sorti uljane repice sa ciljem da se utvrdi njihova pogodnost za ishranu stoke. Najveći prosečni prinos semena po biljci (11,5 g) i najveći sadržaj proteina (21,9 %) imala je sorta Sremica, što znači da se nakon ekstrakcije ulja iz njenog semena može dobiti najveći prinos sačme bogate proteinima. Na osnovu visine biljaka, broja bočnih grana, broja listova i debljine stabla utvrđeno je da sorte Banaćanka, Sremica, Falcon, Duna i Casino poseduju visok potencijal za prinos zelene krme, te da se mogu iskoristiti za neposrednu ishranu stoke u zelenom stanju i kao donori gena u oplemenjivanju na povećan prinos biomase.
