Abstract:Namen raziskave je bil ugotoviti vpliv različnih svetlobnih programov na proizvodnost broilerjev, saj je perutnina zelo občutljiva na dnevno nočni ritem. Testirali smo štiri programe. V programu 1 (23S:1T;20S:4T;23S:1T) so bile živali prvi teden izpostavljene 23-urni svetlobi in 1 uri teme, od 8. do 28. Dne so bile izpostavljene 20 uram svetlobe in 4 uram teme, od 28. Do 35. Dne pa 23 uram svetlobe in 1 uri teme. V programu 2 (24S;20S:4T) so imele živali prvi teden 24 ur svetlobe, potem pa do 20 ur svetlobe in 4 ure teme, živali v programu 3 (23S:1T) so bile 35 dni izpostavljene 23-urni svetlobi in 1 uri teme, medtem ko so imele živali v programu 4 (24S) vse dni 24 ur svetlobe. Ugotavljali smo vplive svetlobnih programov na maso, prirast mase, konverzijo krmil, razmerje voda/krma, pogin in PEF (proizvodna učinkovitost reje). Najnižja masa je bila dosežena v programu 3, ki se statistično značilno razlikuje (P ≤ 0,05) od ostalih programov. Najugodnejša konverzija je v programu 3. Pogin je bil največji v programu 4. V vseh programih PEF ne izkazuje bistvenih razlik. Na podlagi dobljenih rezultatov ugotovimo, da je za rejo najprimernejši program 2 (24S;20S:4T).

Title:The impact of different lightnig programs on broiler production
Abstract:The aim of our study was to determine the effect of different lighting programs on broiler production, as poultry is very sensitive to the day-night rhythm. We tested four programs. In program 1 (23L:1D;20L:4D;23L:1D), animals had 23 hours of light and 1 hour of darkness in week 1, 20 hours of light and 4 hours of darkness during Days 8-28, and 23 hours of light and 1 hour of darkness until day 35. In program 2 (24L;20L:4D), animals had 24 hours of light in week 1, followed by 20 hours of light and 4 hours of darkness. In program 3 (23L:1D), animals had 23 hours of light and 1 hour of darkness all 35 days. In program 4 (24L), animals had 24 hours of light all 35 days. The lowest weight was recorded in program 3 and significantly different from other programs (P ≤ 0,05). Feed conversion was best in program 3. Morbidity rate was highest in program 4. PEF was not significantly different in any program. Based on our results, program 2 (24L;20L:4D), has been the most appropriate for broiler breeding.
