Productive Performance, Ovarian Follicular Development, Lipid Peroxidation, Antioxidative Status, and Egg Quality in Laying Hens Fed Diets Supplemented with Salvia officinalis and Origanum majorana Powder Levels

This study aimed to assess the effect of dietary supplementation with different levels of Salvia officinalis and/or Origanum majorana on productive performance, ovarian follicular development, lipid peroxidation, antioxidative status, and egg quality in laying hens. Two hundred and ninety-four 45-week-old Bovans brown hens were allocated into seven groups, with seven replicates of six hens each. The first group was fed with the basal considered as a control (A); the second (B) and third (C) groups were provided with the same control diet further supplemented with 0.5 and 1 kg/ton Salvia officinalis, respectively; the fourth (D) and fifth (E) groups received the control diet further supplemented with 0.5 and 1 kg/ton Origanum majorana, respectively; while the sixth (F) and the seventh (G) groups were offered a diet supplemented with 0.5 kg/ton Salvia officinalis and 0.5 kg/ton Origanum majorana and 1 kg/ton Salvia officinalis and 1 kg/ton Origanum majorana, respectively. No significant effects were observed in the final body weight (BW) and feed intake (FI) of the laying hens. In the diets supplemented with Salvia officinalis and Origanum majorana, the egg weights for groups C, F, and G had significantly higher values only compared to group D. The supplementation of the diets with Salvia officinalis and/or Origanum majorana significantly (p < 0.05) increased the Follicle stimulating hormone (FSH), luteinizing hormone (LH), and estradiol estrogenic hormone concentration, except for Origanum majorana at both levels with regard to estradiol. The dietary utilization of Salvia officinalis and Origanum majorana did not significantly alter the plasma glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT), total protein, albumin, globulin, and High density lipoprotein (HDL) parameters. Cholesterol, glucose, triglyceride, and Low density lipoprotein (LDL) were decreased (p < 0.05) in the birds fed with Salvia officinalis and/or Origanum majorana supplemented diets. Moreover, at both doses, the dietary supplementation with Salvia officinalis and Origanum majorana decreased (p < 0.05) the yolk cholesterol and liver Malondialdehyde (MDA) levels. In addition, the dietary enrichment with Salvia officinalis and/or Origanum majorana decreased (p < 0.05) the palmitoleic and stearic fatty acids’ egg yolk concentration. In contrast, the yolk linoleic fatty acid concentration was significantly increased by Salvia officinalis and/or Origanum majorana. In conclusion, dietary supplementation with Salvia officinalis and/or Origanum positively affected productive performance, ovarian follicular development, antioxidant activity, hormonal status, and steroidogenesis in Bovans brown laying hens.

Antimicrobial And Antioxidant Activity

Aromatic plants of Labiatae family are used in poultry diets because of their antimicrobial and antioxidant activity. The notion is that hens raised in organic systems face several health and environmental challenges. Hence, the objective here was to assess hens’ performances and the quality of their eggs in such systems following a dietary supplementation of Salvia officinalis L. in powder form. The experiments were conducted over two successive years (1 and 2). They lasted 16 weeks each and involved 198 laying hens aged 40 weeks old randomly assigned to three groups: Con (control diet), Sal-0.5%, and Sal-1.0% (diets supplemented with Salvia officinalis L. at 0.5% or 1.0%, respectively). The malondialdehyde (MDA) levels in egg yolks in year 2 were lower in both Sal-0.5% and Sal-1.0% compared to the Con (p < 0.05). The total number of Enterobacteriaceae in eggshells were lower in Sal-1.0% compared to the Con (p < 0.05) in both years. The results suggest that a dietary supplementation of Salvia officinalis L. at 1.0% improves the antioxidant status and reduces the microbial load of eggs produced in organic systems.

<p>To evaluate the effect of dietary supplementation of DL-methionine and L-lysine in hypoprotein diets on productivity and egg quality, a total of 240 White Leghorn laying hens (Hybrid L-33) of 26 weeks during laying peak period were placed for 49 days, according to completely randomized design with four treatments and 10 repetitions. Dietary treatments consisted of a control diet (no amino acid supplementation) (T0) and supplementation of 0.03% DL-Met and 0.04% L-Lys (T1); 0.06% DL-Met and 0.08% L-Lys (T2) and 0.09% DL-Met and 0.12% L-Lys (T3). At 26 and 33 weeks of age, 30 eggs per treatment were collected to determine internal and external egg quality parameters.</p><p>The experiment diets did not affect the viability and feed intake. Supplementation of essential amino acids, especially the T3 improved egg weight (54.30 to 58.30 g), laying rate (76.89 to 85.45%) and mass conversion (2.52 to 2.11 kg/kg) (P<0.05). At 33 week, the albumin height (7.21 to 8.23 mm), Haugh units (86.70 to 91.15) (P<0.05) and shell surface (67.10 to 69.20 cm2) increased by the effect of supplementation of DL-Met and L-Lys. The results allow recommending the dietary supplementation of 0.09% DL-Met and 0.12% L-Lys in hypoprotein diets to improve productivity and egg quality in laying hens.</p>

The aim of this study was to evaluate the influence of the dietary addition of sodium humate (HAS) on performance and immune response of laying hens during peak lay, over an eight-week period. Laying hens, aged 24 weeks old, were randomly allotted to four dietary treatments: a basal control diet or the basal diet supplemented with 0.1, 0.3 or 0.5% HAS. Each treatment had six replicates with 15 layers per replicate. Egg production, egg quality, serum antioxidant parameters and immunity indexes were measured. HAS had no significant effect on egg production or egg and shell quality, but all supplemental levels significantly improved Haugh unit values and egg yolk colour. Supplementation with all levels of HAS significantly increased serum immunoglobuline (Ig) level compared to the hens fed the control diet. Feeding either 0.1 or 0.5% HAS significantly increased serum IgM levels. The results indicated that dietary supplementation with HAS can enhance egg albumin quality and improve immunity in laying hens.

Vitamin C Supplementation

Abstract Endogenous synthesis of vitamin C may satisfy its requirement for laying hens; however, some previous experiments showed beneficial effects of dietary supplementation of vitamin C in laying hens. Thus, the results are still controversial. The objective of the current experiment, therefore, was to investigate the effect of vitamin C supplementation in diets on productive performance, egg quality, relative organ weight, and tibia strength in laying hens. A total of 504 46-wk-old Hy-Line Brown laying hens were allotted to 1 of 6 dietary treatments with 7 replicates in a completely randomized design. Each replicate had 12 hens. Diets were prepared by supplementing the basal diet with vitamin C at the levels of 250, 500, 1,000, 2,000, or 3,000 mg/kg and were fed to hens for 6 wks. Results indicated that increasing supplementation of vitamin C in diets increased hen-day egg production and egg mass (quadratic, P < 0.05), but decreased production of broken or soft-shell eggs (linear and quadratic, P < 0.01) and feed conversion ratio (quadratic, P < 0.05). These positive effects were observable at the supplementation level of 250 mg/kg vitamin C, but there were no further benefits at the greater levels of vitamin C. Increasing supplementation of vitamin C in diets had no effects on egg quality, except for a decrease (quadratic, P < 0.01) in egg yolk color with increasing vitamin C supplementation. The relative weights of the liver, kidney, and spleen were not affected by increasing supplementation of vitamin C in diets. Tibia strength was not influenced by increasing supplementation of vitamin C. In conclusion, dietary supplementation of vitamin C has a beneficial effect on egg production of laying hens. Quadratic responses of increasing vitamin C supplementation in diets reveal that supplementation of 250 mg/kg vitamin C is recommended for diets fed to laying hens at 46–52 wks of age.

Laying Performance

This study aimed to investigate the supplemental effects of fermented pine (Pinus densiflora) needle extract (FPNE) in laying hen diets on productive performance, egg quality, and serum lipid metabolites. A total of 108 40-week-old Hy-line brown laying hens were randomly assigned to one of the three dietary treatment groups: (1) basal diet + 0 mL FPNE/kg diet (CON), (2) basal diet + 2.5 mL FPNE/kg diet (T1), or (3) basal diet + 5 mL FPNE/kg diet (T2) for 6 weeks. Each group consisted of four replicates of nine hens each. Feed and water provided ad libitum. Results showed that dietary supplementation of FPNE increased egg production percentage (linear, p < 0.01 and quadratic, p < 0.05), egg mass (linear, p < 0.05), and feed intake (linear, p < 0.05) during the entire experimental period. In addition, dietary inclusion of FPNE significantly increased the eggshell color (linear, p < 0.01), egg yolk color (quadratic, p < 0.01), and eggshell breaking strength (linear, p < 0.05 and quadratic, p < 0.05) while the Haugh unit decreased (quadratic, p < 0.05). However, serum lipid profile did not differ among the dietary treatments (p > 0.05). Notably, antioxidant activity of egg yolk was improved by significantly decreasing the malondialdehyde content in egg yolks after 6 weeks of storage (linear, p < 0.001 and quadratic, p < 0.05). In summary, dietary inclusion of FPNE could improve laying performance and the antioxidant capacity of eggs.
