Nutrition effect of pheasant parent flocks to production results

Abstract

This paper presents a literature review of nutrition pheasant parent flocks in aviaries. Nutrition affects to the number, size, and biological quality of the eggs directly from the necessary nutrients that provide by diet, or indirectly through the body’s reserves, which are provided in the past. Comparing the recommendations of the various standards (AEC, INRA, NRC) and the value for the content of nutrients that are used in the experiments and the pheasant, the differences can be observed, especially in the protein content. Norms recent (NRC) calls on the similarity between the needs of pheasants and turkeys and recommend optimal balance of protein and energy (Mcal ME for each maximum 5.6% protein). By the way, in recent experiments, more attention is paid to micronutrients (trace elements, vitamins), physical form of concentrated feed and the etc. Because of these problems and shortcomings it is necessary to continue research, to the current recommendations for nutrient content corrected in order to reduce feeding costs and achieve better results of parent flocks.

U radu je dat pregled literaturnih podataka iz ishrane matičnog jata fazana u volijerama. Ishrana utiče na broj, veličinu i biološki kvalitet jaja direktno preko neophodnih hranljivih materija koje se obezbeđuju obrokom, ili indirektno preko telesnih rezervi koje su obezbeđene u ranijem periodu. Poređenjem preporuka iz različitih normativa (AEC, INRA, NRC) i vrednosti za sadržaj hranljivih materija koje se koriste u eksperimentima i na fazanerijama, mogu se uočiti razlike, pre svega u sadržaju proteina. Normativi novijeg datuma (NRC) pozivaju se na sličnost potreba fazana i ćuraka i preporučuju optimalan odnos energije i proteina (za svaku Mcal ME maksimalno 5,6% proteina). Osim toga, u eksperimentima novijeg datuma više pažnje se poklanja mikro-hranivima (mikroelementima, vitaminima), fizičkoj formi koncentrovane hrane i sl. Zbog navedenih problema i nedostataka neophodno je nastaviti istraživanja, kako bi se dosadašnje preporuke za sadržaj hranljivih materija korigovale, u cilju smanjenja troškova ishrane i postizanja boljih proizvodnih rezultata matičnog jata.
