“…Feed conversion ratio at the end of fattening was lower in experimental groups (1.64 to 1.67), compared with control (1.69), which is in compliance with the results by Shalmany and Shivazad (2006), who also recorded a decrease of FCR after the application of propolis extract in the diet of chickens Ross 308. The results of FCR are comparable with values achieved by Haščík et al (2010), but Novel et al (2009) found the FCR in 42-days old chickens at the level of 2.20 to 2.30. Inconclusive differences (P ≥ 0.05) in FCR between control and experimental groups are in compliance with the results by Demir et al (2003), Acikgoz et al (2004), Botsoglou et al (2004), Gunal et al (2006), Mohamed et al (2008), Seven et al (2008), respectively Tekeli et al (2011), who point that extracts from plants and propolis do not have a significant impact on improving FCR.…”

The focus of the study was the performance of Ross 308 chickens after the application of propolis extract in their diet. The nutritional value of feed mixtures for chickens was equal, but the experimental groups were also added propolis extract in the dose of 200 mg.kg -1 (E1), 300 mg.kg -1 (E2) and 400 mg.kg -1 (E3), respectively. The results of the experiments showed that the propolis extract in the examined concentrations can be applied to the diet of chickens, since it managed to raise (P ≥ 0.05) the body weight positively (E1 -2354.60 g; E2 -2371.40 g; E3 -2382.90 g), compared to control group (2272.89 g). Total increase of body weights indicates positive tendency of propolis extract in the diet of chickens Ross 308, because higher values (P ≥ 0.05) were reached in the experimental groups (2311.60 g -E1 to 2339.60 g -E3) compared to control (2230.80 g). Total feed consumption was higher in the experimental groups, on the contrary, FCR was lower (P ≥ 0.05) in the experimental groups (1.64 to 1.67) compared to control (1.69). The best performance results were reached in the group with the greatest addition of propolis extract, i.e. in the dose 400 mg.kg -1 of feed mixtures (E3). AbstraktŠtúdia bola zameraná na skúmanie úžitkovosti kurčiat Ross 308 po aplikácii propolisového extraktu v ich výžive. Výživná hodnota kŕmnych zmesí pre kurčatá bola rovnaká, ale pokusným skupinám bol navyše pridávaný extrakt propolisu v dávke 200 mg.kg -1 (E1), 300 mg.kg -1 (E2) a 400 mg.kg -1 (E3). Výsledky experimentu preukázali, že propolisový extrakt v preverovaných koncentráciách môžeme aplikovať vo výžive kurčiat, nakoľko pozitívne (P ≥ 0,05) zvyšoval živú hmotnosť (E1 -2354,60g; E2 -2371,40 g; E3 -2382,90 g) oproti kontrolnej skupine (2272,89 g). Celkový prírastok živej hmotnosti tiež poukazuje na kladnú tendenciu využitia propolisového extraktu vo výžive kurčiat Ross 308, nakoľko vyššie hodnoty 133 (P ≥ 0,05) boli dosiahnuté v pokusných skupinách (2311,60 g -E1 až 2339,60 g -E3) oproti kontrole (2230,80 g). Celková spotreba krmiva bola vyššia v pokusných skupinách, ale konverzia krmiva bola naopak nižšia (P ≥ 0,05) v pokusných skupinách (1,64 až 1,67) oproti kontrole (1,69). Najlepšie výsledky úžitkovosti boli dosiahnuté v skupine s najvyšším prídavkom propolisového extraktu, t.j. v množstve 400 mg.kg -1 kŕmnej zmesi (E3).Kľúčové slová: kurčatá Ross 308, výživa, úžitkovosť, propolisový extrakt Detailný abstraktŠtúdia sa zamerala na skúmanie mäsovej úžitkovosti kurčiat Ross 308 po aplikácii propolisového extraktu v ich výžive. Experiment sa realizoval v testovacej stanici hydiny Katedry hydinárstva a malých hospodárskych zvierat pri Fakulte agrobiológie a potravinových zdrojov, Slovenskej poľnohospodárskej univerzity v Nitre. Do pokusu sa zaradilo 360 ks jednodňových kurčiat a následne sa vytvorili 4 skupiny zvierat: kontrolná (K) a tri pokusné (E1, E2, E3) po 90 ks kurčiat. Vlastný výkrm trval 42 dní. Kurčatá sa kŕmili systémom ad libitum rovnakou štartérovou kŕmnou zmesou HYD-01 (sypká štruktúra) do 21. dňa veku a od 22. dňa...

“…This result agrees with De Silva and Kalubowila (2012) and Netshipale et al (2012) who observed the same feed intake of restricted birds. The results of feed intake in this study do not agree with Novel et al (2009) and Boostani et al (2010) who reported reduced feed intake of restricted birds. The insignificant differences in feed conversion ratio of control, 3 and 6 h restricted group follow the findings of Dozier et al (2002) and Khajali et al (2007).…”

In a completely randomized design, one hundred and twenty one-day old (Arbor acres) broiler chicks were randomly distributed in three treatments, five replicates with eight chicks per a replicate. The treatments were: 24 h ad libitum feeding (A), B feed removal from 9:00 to 12:00 noon (3 fasting hours) and C feed removal from 9:00 to 3:00 pm (6 fasting hours). Feed restriction was applied from 8 to 28 days of age. The experiment lasted from 8 to 37 days of age. The results showed that fasting birds for three and six hours had significantly (p<0.05) no effect on body weight, weight gain, feed intake and feed conversion ratio at 37 days of age.

“…Consequently, in our study, 27 and 20 d of re-alimentation after 7 and 14 d of feed restriction, respectively, allowed to fully recover the RW of breast. Novel et al (2009) and Onbaşilar et al (2009) showed that feeding restriction had limited effect on carcass characteristics. Ocak and Sivri (2008) reported that, during re-alimentation period, the carcass components reacted more rapidly than the whole body.…”
