Effect of different levels of honey on physiological, growth and carcass traits of broiler chickens during dry season

Abstract

Effect of different levels of honey on physiological, growth and carcass traits of broiler chickens during dry seasonThe 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.Key words: poultry; broiler chickens; animal nutrition; honey; growth; physiological traits; carcass traits; hot dry season Učinek dodajanja različnih količin medu na fiziološke, rastne in klavne lastnosti pitovnih piščancev v sušnih razmerah 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.Ključne besede: perutnina; pitovni piščanci; prehrana ži-vali; med; rast; fizološke lastnosti; klavne lastnosti; vroče sušno obdobje bient temperature and high humidity which have been reported to affect the productive performance of chickens (Ahmad et al., 2005;Daghir, 2008).

The Physiological Response to Bee Honey Application in Broiler Chicken Diets

“…Dietary BH supplementation to broiler chickens caused numerical decreases in plasma levels of cholesterol and triglycerides compared with that of control group (Table 3). These results agree with those of Oke et al(2016) and Osakwe and Igwe (2015), who reported that the reduction in blood cholesterol and triglycerides concentrations was the most beneficial effect of BH on the blood lipid profile. On the other hand, our results disagree with Osunkeye et al (2016), who indicated that BH supplementation had no effect on plasma cholesterol and triglycerides in broiler chickens.…”

“…Plasma transaminases (AST and ALT) activity was significantly decreased (P≤0.05) in most treated groups with BH compared with the control group. This result agrees with that of Oke et al (2016), who found a decrease in activity of plasma AST and ALT enzymes in birds fed on diets supplemented with BH. These authors also indicated that the treatment with BH is beneficial and safe through modulating the liver functions.…”

“…These results partly agree with those of Oke et al (2016), who reported that there were an increase in the percentage of carcass weight, liver, heart, gizzard and edible parts due to addition of BH at levels of 20, 40 and 60 ml/ liter in drinking water. Also, Obun et al (2008) reported that the addition of BH in finisher broiler diets increased the percentage of abdominal fat.…”

“…The birds fed the diets supplemented with 0.15 or 0.20% BH displayed significantly higher (P≤0.05) means of total protein and globulin than did other dietary treatments. These results agree with those of Oke et al (2016), Osakwe and Igwe (2015) and Obun et al (2008), who reported that addition of BH in broiler diets improved plasma concentrations of total protein, globulin and A/G ratio, which might be attributed to improvement in digestion of crude protein and thus more availability of amino acids required for endogenous protein biosynthesis induced by oral administration with BH. Also, the increase in globulin level with increasing dietary or drinking water levels of BH could be attributed to the improved immune status of birds (Gheldof and Engeseth 2002), through better efficacy of the liver to synthesize enough globulins for immunological functions.…”

Influence of intravenous Egyptian fennel honey infusion on the antioxidant activities and some haemo-indices in healthy goats

“…64 Total serum globulins (Figure 4) increased significantly by the 1 st and the 4 th week respectively post intravenous infusion, while and ascorbic acid ( Figure 5) increased but not significantly. Daily ingestion of 20% solution from floral-undetected Nigerian honey 65 or intraperitoneal of 10% Egyptian 66 fennel honey solution increased serum globulin and ascorbic acid levels, 65 while daily ingestion of acasia Pakistanish honey up to 50% did not alter the serum globulin level. 67 Vitamin C raises intracellular glutathione levels and playing an important role in protein thiol group protection against oxidation, so honey vitamin C content will magnify its antioxidant effect as the profound antioxidant efficacy might be due to the synergistic action of the polyphenols such as flavonoids, and other compounds such as vitamin C. 68…”
