Effect ofLeuconostoc mesenteroidesKCCM35046 fermented aged garlic extract on egg production, egg quality, odour gas emissions, targetedE. colicolony, haematological characteristics and fatty acids composition of egg yolk in laying hens

Abstract

The design of this study was to investigate the impacts of dietary supplementation with aged garlic extract (AGE) by Leuconostoc mesenteroides KCCM35046 on egg production, egg quality, odour gas emissions from excreta, excreta microbiota, haematological characteristics and fatty acids composition of egg yolk in laying hens. A total of 384, 54-week (ISA-brown) laying hens were randomly assigned to one of four treatments with eight replications per treatment and 12 adjacent cages as a replication. The experimental treatments were: (1) CON; basal diet, (2) AGE.05; CON + .05% aged garlic extract, (3) AGE.1; CON + .1% aged garlic extract, (4) AGE.2; CON + .2% aged garlic extract. No significant differences were observed in feed intake (FI) and egg production among treatments (P > .05). Laying hens fed with the AGE linearly improved yolk height at Week 3 (P = .02). The inclusion of .1% AGE had increased Haughunit (HU) at Week 4 (quadratic, P = .01). At the end of the experiment, AGE diet linearly increased yolk height and egg shell thickness (P = .01 and .03, respectively). No significant differences were observed in excreta gas emission (P > .05). The supplementation of AGE linearly reduced excreta E. coli concentrations (P = .02). Inclusion of AGE led to a greater lymphocyte and IgG concentrations (linear, P = .04 and P = .03, respectively), whereas blood total cholesterol (TC) was reduced by the AGE supplementation (linear, P < .01). PUFA: SFA was increased in AGE treatment at the end of the experiment (P < .05). In conclusion, the administration of AGE at a level of .1 and/or .2% can improve egg quality, blood lymphocyte, IgG concentrations and reduced excreta E. coli and blood TC in the laying hens.ARTICLE HISTORY

The nutritional applications of garlic (Allium sativum) as natural feed additives in animals

“…In contrast, Reddy, Lightsey & Maurice (1991) and Chowdhury, Chowdhury & Smith (2002) did not find garlic paste or garlic oil affect egg weight. Similarly, Hossain, Begum & Kim (2016) also reported that no change was observed in the egg weight of laying hens fed diets supplemented with aged garlic extract by Leuconostoc mesenteroides KCCM35046. Whereas Khan, Sardar & Anjum (2007) found that laying hens fed on 2–8% dried garlic had increased egg-production intensity along with improved egg mass.…”

“…However, these observations were different from the findings reported by Yalcın et al (2006) , who observed that garlic did not significantly affect egg albumin, shell index, yolk index and HU values when the diets of laying hens were supplemented with garlic powder (0.5% or 1%) for 22 weeks. Kaya & Macit (2012) also found dried garlic powder did not positively influence eggshell thickness and HU in laying hens, furthermore, no change was found in the eggshell color, eggshell strength and yolk color ( Hossain, Begum & Kim, 2016 ). The present studies cleared that inclusion of garlic powder in laying hens increased the egg weight, yolk weight, yolk color, and HU, but no effects on eggshell.…”
