dc.description.abstractIt is examined the effects of high levels organic selenium (selenium yeast) on body weight, concentration Se in blood plasma and mortality of chickens. The experiment is carried with 100 Hybro chickens, which are divided in 5 groups. The experiment lasted 42 days. Chickens are fed with standardized diets in which are added 0, 2, 5, 10 or 15 mgSe/kg diet. Chickens fed with 2 mgSe/kg diet (group II) by seventh day to the end of fourth week are registered the important higher body weight in relate to I group (P lt 0,05*; P lt 0,01**). At the end fifth week chickens of II group had a little higher body weight than the chickens of first group, but at the end of sixth week their body weight were the same. The chickens of III group had (5 mgSe/kg feed) had until fifth week of experiment higher body mass in relate to chickens first group, but this differences were not statistical significant (P>0,05*). At the end of the experiment (sixth week) the their body weight was little lower then body mass chickens of first group. Chickens of IV and V group (10 and 15 mgSe/kg feed) had little higher increasing than chickens first group until fifth week of the experiment, but at the and of the experiment chickens IV group had lesser body weight, and chickens of V group bigger body mass then chickens of I group. The concentration of selenium in blood plasma of chickens fed with high levels of organic selenium (groups II, III, IV and V) was importantly higher (P lt 0,05*; P lt 0,01**) with all experimental periods in relate with I group. The concentration of selenium in blood plasma was increased with increasing of level of selenium in diet and time exposure. The highest level of selenium in blood plasma are established at the and of experiment (sixth week), with all experimental group. There were not effects on mortality of chickens fed of the high level organic selenium.en
dc.description.abstractIspitivan je uticaj visokih nivoa organskog selena (seleniziranog kvasca) na porast, koncentraciju selena u krvnoj plazmi i mortalitet pilića. Ogled je izveden na 100 dvodnevnih Hibro pilića podeljenih u pet grupa. Eksperiment je trajao 42 dana. Pilići su hranjeni standardnim smešama u koje je dodato 0, 2, 5, 10 ili 15 mgSe/kg hrane. Pilići hranjeni sa 2 mgSe/kg hrane (grupa II) imali su značajno višu telesnu masu u odnosu na I grupu (P lt 0,05*; P lt 0,01**) od prve do kraja 4. nedelje tova. Na kraju 5. nedelje telesne mase su se neznatno razlikovale, dok na kraju 6. nedelje telesne mase su im bile iste. Pilići III grupe (5 mgSe/kg hrane) imali su do 5. nedelje tova višu telesnu masu nego pilići I grupe, ali ove razlike nisu bile statistički značajne (P>0,05*). Na kraju tova (6. nedelje) njihova telesna masa je bila čak i nešto niža, nego telesna masa pilića I grupe. Jedinke IV i V grupe (10 i 15 mgSe/kg hrane) imale su nešto veći prirast nego grla I grupe sve do 5. nedelje tova, da bi na kraju tova pilići IV grupe imali manju, a V grupe veću telesnu masu nego pilići I grupe. Koncentracija selena u krvnoj plazmi pilića hranjenih visokim nivoima organskog selena (grupe II, III, IV i V) bila je značajno viša (P lt 0,05*; P lt 0,01**) u svim ispitivanim periodima u odnosu na I grupu. Koncentracija selena u krvnoj plazmi se povećavala sa povećanjem nivoa selena u hrani i dužinom ekspozicije. Kod svih oglednih grla najviši nivoi selena u krvnoj plazmi ustanovljeni su na kraju tova (6. nedelje). Visoki nivoi selena nisu imali uticaja na mortalitet pilića.sr
