Effect of different levels of honey on physiological, growth and carcass traits of broiler chickens during dry season | Učinek dodajanja različnih količin medu na fiziološke, rastne in klavne lastnosti pitovnih piščancev v sušnih razmerah

إنجليزي. The objective of this trial was to investigate the effect of different levels of honey in drinking water on the responses of broiler chickens during dry season in hot humid tropics. Three hundred Oba Marshall broiler chicks were used for this study. The day-old chicks were randomly assigned to five treatment groups with each treatment having four replicates of 15 birds. The first 4 treatment groups were daily supplied drinking water without honey (0H), with 20 ml (20H), 40 ml (40H) and 60 ml (60H) of honey per liter of water. The fifth group received drinking water supplemented with 500 mg vitamin C per liter of water (C). Records on daily weight gain (WG) and feed intake (FI) were taken. Feed conversion ratio (FCR) was calculated as the ratio of gain to feed consumed. The supplementation of honey in the drinking water for broiler chickens in 60H during hot dry season in the hot humid tropics improved some stress indices, body weight gain and relative spleen weight.

السلوفينية. Cilj raziskave je bil proučiti vpliv dodajanja različnih količin medu v pitno vodo pitovnih piščancev med vročim in suhim obdobjem v vročih in vlažnih tropih. Za to študijo smo uporabili 300 pitovnih piščancev provenience Oba Marshall. Enodnevni piščanci so bili naključno razporejeni v pet poskusnih skupin, s štirimi ponovitvami s po 15 piščanci v vsaki skupini. V prvih štirih skupinah so piščanci dobivali pitno vodo brez medu (0H), z 20 ml (20H), 40 ml (40H) in 60 ml (60H) medu na liter vode. Peta skupina je dobivala pitno vodo, dopolnjeno s 500 mg vitamina C na liter vode (C). Merili smo dnevne priraste (WG) in količino zaužite krme (FI). Izkoriščanje krme (FCR) smo izračunali kot razmerje med prirastom in porabo krme. Dodatek medu v pitni vodi za pitovne piščance v skupini 60H v vročem in sušnem obdobju v vročih in vlažnih tropih je izboljšal nekatere pokazatelje stresa, pitovne lastnosti in povečal relativno maso vranice.
