Production results of various categories of pheasants reared under controlled conditions

Abstract

The overview of domestic and foreign investigations of the effects of various intensity of ant feeding technique in various categories of pheasants. With the aim to increase number of pheasants in our country and in the world, for decades pheasant chicks are produced in pheasant farms up to the age of 5-8 weeks, and body mass of 400-450 g, after which they are released into the hunting grounds. The capacity of pheasant farms in Serbia is about 900.500 hatched chicks, and in the past four decades several tens of millions of artificially reared pheasants were released. The quality of feeding the brood stock of pheasants, which produce eggs for hatching incubator has a direct influence on number, mass and fertility of eggs, and on the mass of newly hatched chicks. The feed conversion ratio in chicks depends on the first place on energy and protein level, and also on biological value of protein. In domestic investigations of pheasant chicks feeding with the concentrate mixture with higher protein value (30% to 28 days of age and 24% to 42 days of age) and with lower stocking density (450 individuals in the group), had significantly bigger Final body mass (457.07 g) and higher daily gain (4.22 g in the first 13:31 and g in the second period), and with better feed conversion ratio.

U radu je dat pregled domaćih i stranih istraživanja efekata različitog intenziteta i tehnike ishrane na proizvodne rezultate različitih kategorija fazana. U cilju povećanja broja fazana za odstrel u svetu i kod nas decenijama se gaje fazančići u fazanerijama do starosti od 5-8 nedelja i telesne mase od 400-450 g a zatim se puštaju u lovišta. Kapacitet fazanerija u Srbiji je oko 900.500 jednodnevnih fazančića a za protekle četiri decenije u lovišta Srbije pušteno je nekoliko desetina miliona veštački odgajenih fazana. Kvalitet ishrane matičnog jata fazana koji proizvode jaja za inkubatore direktno utiče na broj, masu i fertilitet jaja, kao i na masu fazančića. Konverzija hrane kod fazančića zavisi od nivoa energije i proteina, kao i od biološke vrednosti proteina, pre svega od sadržaja metionina i lizina. U domaćim ispitivanjima ishrana fazančića smešom koncentrata sa većim nivoom proteina (30% do 15. dana života i 24% do 42. dana) i pri manjoj gustini naseljenosti (450 jedinki u grupi) rezultovala je signifikantno većom završnom telesnom masom (457,07 g) i većim dnevnim prirastima (4,22 g za prvi period odgajivanja i 13,31 g za drugi period), kao i boljom konverzijom hrane.
