-With the objective to establish the best metabolizable energy (ME) intake for layers, and the best dietary vegetable oil addition level to optimize egg production, an experiment was carried out with 432 30-week-old Hisex Brown layers. Birds were distributed into nine treatments with six replicates of eight birds each according to a 3 × 3 factorial arrangement, consisting of three daily metabolizable energy intake (280, 300 or 320 kcal/bird/day) and three oil levels (0.00; 0.75 and 1.50 g/bird/day). Daily feed intake was limited to 115, 110 and 105 g/bird in order to obtain the desired energy and oil intake in each treatment. The following parameters were evaluated: initial weight, final weight, body weight change, egg production, egg mass, feed conversion ratio per dozen eggs and per egg mass and energy conversion. There was no influence of the treatments on egg production (%) or egg mass (g/bird/day). Final weight and body weight change were significantly affected by increasing energy intake. Feed conversion ratio per egg mass, feed conversion ratio per dozen eggs and energy conversion significantly worsened as a function of the increase in daily energy intake. An energy intake of 280 kcal/bird/day with no addition of dietary oil does not affect layer performance.

“…Significant decreases in hepatic 3-hydroxy-3-methylglutaryl-CoA reductase, cholesterol 7α-hydroxylase, fatty acid synthetase and in representative pentose phosphate pathway activities accompanied the feeding of petroleum ether, methanol and water-soluble fractions of garlic (Qureshiet al 1983). In contrast, Reddy et al (1991) reported that feeding .02% garlic oil did not have any effect on serum and yolk cholesterol in the Babcock B-300 strain. This result might be due to the strain used in the experiments because serum cholesterol concentrations differ significantly among strains (Chowdhury et al 2002).…”

“…Similarly, Chowdhury et al (2002) observed that feed consumption, egg production and feed efficiency were not significantly affected by 0-100 g/ kg sun-dried garlic paste over six weeks. According to Reddy et al (1991), egg production and feed efficiency were not affected during or at the end of eight weeks of feeding garlic oil to the Babcock layer. Canogullari et al (2009) fed layer diets containing 0, .5, 1 and 2% garlic powder for 12 weeks period and also reported that feed consumption and feed efficiency were not affected by the diets.…”

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

“…In agreement with the present study, Khan et al (2007) reported that egg production and feed consumption were affected during the six weeks in which 0, 2, 6 or 8% garlic powder was fed to the laying hens. In contrast, Chowdhury et al (2002) and Reddy et al (1991) reported that feed consumption, feed efficiency and egg production were not affected by supplements of 0, 2, 4, 6, 8 or 10% garlic paste (P > 0.05) as averaged over the 6-week period or by supplements of 0.02% garlic oil over eight weeks. The reason for this difference might be the duration of the experiment and the fact that different garlic products were used.…”

ABSTRACT:This study was conducted to investigate the effects of garlic powder on the performance, egg traits, egg cholesterol and serum parameters of laying Japanese quails. One hundred and twenty 10-weeks-old quails were allocated to four dietary treatments. Quails were caged individually and fed diets supplemented with 0 (control), 1, 2, 4% garlic powder for 12 weeks. There were significant (P < 0.05) differences among the diets in feed consumption, feed efficiency and egg production as averaged over 12 weeks. The better values for these parameters were obtained from the 1% garlic powder supplemented group. Garlic powder addition did not significantly affect egg yolk index, egg shell weight and egg shell thickness. However, there were significant differences (P < 0.05) in egg albumen index, egg shell index and Haugh unit. There was a significant (P < 0.05) reduction in the egg yolk cholesterol concentration when the dietary level of garlic powder was increased from 0 to 4 g/kg. Plasma high density lipoprotein (HDL) cholesterol concentrations increased (P < 0.05) with increasing levels of dietary garlic powder. Plasma cholesterol (P < 0.05) and triglyceride (P < 0.05) concentration decreased with garlic powder supplementation. It was concluded that garlic powder in the diet of laying quails reduced the plasma and egg yolk cholesterol concentration.
