Trial Analysis

Effects of Mentha piperita (peppermint) extract and juice on performance and immune parameters were evaluated in laying hens. A total of 252 Babcock laying hens were allocated to seven treatments with four replications of nine hens. The control hens were fed a basal diet without supplementation. Other hens were given diets supplemented with mentha extract (ME) at 50 (50ME), 100 (100ME), and 200 (200ME) mg/kg of feed or with 50 mentha juice (50MJ), 100 (100MJ) and 200 (200MJ) mg/L that was provided in the drinking water. No significant differences were detected among treatments in bodyweight, feed intake, egg mass, egg production, eggshell breaking strength, Haugh unit, and haematological and serological parameters. The ratio of gram feed to gram egg mass (feed conversion) was significantly better in the birds that received 100ME and 200ME compared with the control hens. The yolk colour index was higher in mid trial analysis (28th day). Thus, although the ME supplementation had a positive effect on feed conversion ratio and egg yolk colour at dosage rates up to 200 mg/kg, further research is needed to establish the efficacy of this herbal product and to determine the most appropriate amount to include in diets for laying hens.

Abstract An experiment was conducted with 64 Tetra SL laying hens (placed into four groups) to determine the AMEn value of feed grade crude glycerol (DM 92%; glycerol 86.80%; methanol 0.04%; fat 0.49%; ash 4.67%; GE 15.59 MJ/kg). All groups were given a 100 g basal diet per day (AMEn value 11.46 MJ/kg; protein 16.97%; Ca 3.49%; P (non-phytate) 0.56%; lysine 0.82%; methionine 0.40%; cysteine 0.29%; threonine 0.60%; tryptophan 0.19%), which was supplemented with 5%, 7.5% and 10% glycerol for the three experimental groups. Hens were placed in metabolism cages (4 hens/treatment in four replicates). After a 10-day adaptation period, excreta was collected and weighed individually for 10 days. The AMEn value of crude glycerol (86%) was calculated as 15.30 MJ/kg for laying hens. During the experiment, egg production (90.0-90.8%), egg weight (56.8-58.0 g) and egg mass (51.2-52.7 g) were not affected by dietary treatments. Feed conversion was significantly reduced by a 10% glycerol supplementation. We concluded that crude glycerol’s energy is efficiently used by laying hens, and more efficiently than by broilers. The established 15.30 MJ/kg AMEn value of crude glycerol when fed in the daily ration to laying hens means that they utilized 97.6% of the glycerol’s GE content.

Completely Randomized Design

This study evaluated the effect of pequi peel meal in the diet for laying hens on performance and egg quality. Hy-Line® Brown hens (n=160) aged 55 weeks with 1642±63g body weight were distributed in a completely randomized design with five treatments and four replications of eight birds each. The treatments consisted of isometric substitution of corn by pequi peel meal at 0, 2.5, 5.0, 7.5 and 10%. The performance and internal and external egg quality were evaluated. Egg production, egg mass and feed conversion worsened linearly with increasing replacement of corn with pequi peel meal, while the yolk color increased linearly. The other variables related to performance and internal and external egg quality were not significantly affected by the treatments. It can be concluded that the use of pequi peel meal replacing corn in laying hen diet does not change the internal and external egg quality, improves the pigmentation of egg yolk, and impairs performance of laying hens.

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.

The objective of this study was to evaluate egg production and quality after including crude corn oil with high acidity (CCOHA) in the feed of laying hens. The design was completely randomized to three treatments and six replicates each. The sample included 90 hens of the Lohmann LSL lineage, housed in cages; each cage contained five animals and constituted an experimental unit. The evaluated feeds were corn-based feed with degummed soybean oil (CSO), corn-based feed with CCOHA (CC) and sorghum-based feed with CCOHA (SC). At the end of the 28-day cycle, the following productivity parameters were evaluated: egg weight at laying (EWL), laying percentage (LP), feed conversion per dozen eggs (FCDZ) and feed conversion per egg mass (FCEM). The evaluated internal and external quality parameters of the eggs were yolk percentage (YP), yolk index (YI), and yolk pH (YpH); albumen percentage (AP), albumen index (AI), and albumen pH (ApH); percentage shell (PS) and shell surface area (SSA); Haugh unit (HU) and egg yolk color (EYC). There were no significant differences in EW, LP, FCDZ, and FCEM between the experimental feeds. Moreover, the use of crude corn oil with high acidity in laying hens rations did not influence the parameters of YP, YI, YpH, AP, AI, ApH, PS, SSA, HU, and EYC.

This study was carried out to evaluate the energy levels in the diet to obtain better performance rates and quality of eggs from laying hens in the second production cycle. One hundred and eighty Bovans Goldline laying hens with 62 weeks of age were used during four 28-day periods. A completely randomized experimental design was used with four metabolizable energy levels (2,650, 2,725, 2,800, 2,875 and 2,950 kcal/kg), each with six replicates of six birds. The energy level of diet did not affect the weight of the egg, yolk, albumen and eggshell, the percentages of yolk, albumen and eggshell, yolk color and egg specific gravity. Feed intake, egg production, egg mass and feed conversion per egg mass and per dozen eggs increased significantly with increasing levels of metabolizable energy. Feed intake decreased linearly as the energy level in the diet increased. The metabolizable energy levels showed a quadratic effect on egg production, egg mass and feed conversion per egg mass and per dozen eggs. The metabolizable energy level of 2,830 kcal/kg was the most appropriate to promote better performance and quality of eggs from laying hens in the second production cycle.

Main Effects

The effects of peeling and limestone flour level on the utilisation of Alocasia macrorrhiza corm meal (ACM) by laying hens were investigated. Maize-based diets with two concentrations of limestone flour (40 and 60 g/kg) and diets containing 200 g peeled and unpeeled ACM meal/kg with the same levels of limestone flour were fed to five replicate pens containing 10 20-week-old Shaver brown pullets (1635 ± 148 g), each for 105 days. Results showed no interaction or main effects of ACM or limestone concentration on feed intake, egg weight, egg mass, feed conversion efficiency, egg shape index, surface area and Haugh unit (P &gt; 0.05). Feeding whole ACM with 40 g limestone/kg diet reduced hen-day production and shell thickness (P &lt; 0.05) but this was overcome by increasing limestone concentration to 60 g/kg diet. Peeled ACM with both concentrations of limestone flour maintained laying performance and egg quality. We concluded that feeding 200 g whole ACM depresses egg production and shell quality in laying hens, but increasing dietary limestone concentration overcomes this adverse effect. The concentration of limestone flour in the diet has no effect on laying performance. Higher inclusion levels of ACM, calcium source and level that will maintain laying performance and reduce feed cost need to be investigated.

Context Organic and herbal additives in feed may lead to more healthy animal products. For this study, we hypothesised that an organic form of selenium and/or a herbal additive (oregano, Origanum vulgare L.) may improve performance of laying hens. Aims The study was designed to determine the effects of selenium source (SS, sodium selenite; or selenium yeast, SY), oregano essential oil (OEO) and a combination of Se and OEO on performance, egg quality and blood parameters of laying hens. Methods In total, 216 Lohmann LSL-Lite laying hens, 66 weeks of age, were assigned to feed on one of six diets: control group, receiving basal diet (BD); BD + 0.3 mg SS/kg; BD + 0.3 mg SY/kg; BD + 250 mg OEO/kg; BD + 250 mg OEO + 0.3 mg SS/kg; BD + 250 mg OEO + 0.3 mg SY/kg. For each treatment, there were six replicates of six hens each for 12 weeks. Key results Feed conversion ratio was higher (P &lt; 0.05) with the OEO diet than in the control. The SY diet decreased egg production and the OEO diet decreased egg mass (P &lt; 0.05), although this effect was reversed with the SY + OEO diet. This would illustrate a synergistic effect of OEO with SY. Highest and lowest yolk colour values were found with the SY and SS diets, respectively (P &lt; 0.05). Serum uric acid was lower with diets containing Se than the control diet (P &lt; 0.05). Glutathione peroxidase activity was highest with SY and SY + OEO diets and lowest with the OEO diet (P &lt; 0.05). Birds fed the SS + OEO diet showed the highest total antioxidant capacity and those fed SY showed the lowest total antioxidant capacity (P &lt; 0.05). Conclusions Based on the results of the current study, it can be concluded that SY diet have increasing effect on egg weight in laying hens. In addition, novel synergistic effects between OEO and SY diets on improving egg production, egg mass and feed conversion ratio have been found. In terms of oxidative status, the detected synergistic effects between OEO and SS diets on total antioxidant capacity and between OEO and SY diets on glutathione peroxidase (GPx) have not been reported before, that appreciate more clarifying investigations in future. Although, dietary supplemental SY individually and also with OEO increased GPx, adding SS to diet together with OEO showed more improving effect on GPx compared to the separate usage. Implications Dietary supplemental SY can improve egg weight in laying hens. In addition, adding SY to diet of laying hens individually and with OEO have beneficial effects on oxidative status of bird in terms of GPs activity, which in turn can ameliorate the unfavourable impressions of probable environmentally oxidative stress on productive performance.

 The environment is very important for the performance of laying hens; thus, techniques are required to improve production systems, providing better welfare for poultry and consequent increase in the quality of the final product, the egg. This study aimed to evaluate the effects of rearing system, on the floor and in cage, on the performance and egg internal and external quality of laying hens. A total of 320 Hysex Brown laying hens, with 34-43 weeks days of age, was distributed in a completely randomized design, with two treatments, floor and cage, with 10 replicates each. The parameters evaluated were: individual feed intake, egg production per replicate, feed conversion per dozen eggs, egg weight; weight and percentage participation of shell, albumen and yolk, specific gravity, body weight variation and viability of birds. The results show that the birds raised on the floor showed best results as to egg production, besides the best internal and external quality, with greater weight of egg, yolk, albumen, shell and with lower losses of eggs. Because of the negative effects of the cage system, in general, hens presented lower results when compared to results of those raised on the floor.

ABSTRACTThe use of antibiotics in chicken feed is currently banned because it can cause resistance to pathogenic bacteria and cause residues in products. This study aimed to see the effect of drinking water containing uronic acid extracted from Sargassum crassifolium (S. crassifolium) on the physical and chemical quality of Lohmann chicken eggs. One hundred and twenty laying hens were divided into 2 groups: (1) chickens given commercial feed containing antibiotics and (2) feed without additional antibiotics. The chickens were randomly assigned to one of the 5 brown seaweed supplementation treatments in drinking water A1=0.0% S.crassifolium (control); A2=2.5% S.crassifolium; A3=5.0% S.crassifolium; A4=7.5% S.crassifolium; A5=10.0% S.crassifolium. The study used a completely randomized factorial design of 5 treatments, 2 factors, and 3 replications. Each replication consisted of 6 heads of laying hens. There were no differences between treatments on the performance of laying hens (egg production, egg weight, egg mass, feed conversion); physical quality (eggshell, egg yolk, egg white, shell thickness, egg yolk, Haugh unit, egg index) and chemistry (superoxide dismutase production, thiobarbituric acid reactive substances (TBARS) and Lohmann chicken egg cholesterol) but there was a difference in feed intake. The uronic acid extracted from S. crassifolium has not been able to increase the production and quality of Lohmann chicken eggs.Keywords: lohmann chicken, quality of eggs, Sargassum crassifolium, uronic acid

This study was conducted to know the production performance of laying hen by using different graded level of linseed. At 56 weeks of age, a total of 160 laying hens were raised up to 63 weeks of age. All hens were fed a basal corn soyabean meal diet. The experiment was allowed 4 dietary treatments (T0, no addition of whole linseed in the basal diet; T1,  addition of 5% whole linseed; T2, addition of 10% whole linseed and T3, addition of 15% whole linseed) with 5 replications and per replication contains eight hens. Egg production, feed intake, egg weight of each treatment was recorded. Egg samples were collected and analyzed for egg quality. The results showed that egg production and egg mass (kg) exhibited for all dietary treatment groups were unaffected (P>0.05) by feeding linseed to the laying hens. Feed Conversion Ratio (FCR) was found significant difference within the four dietary group (P<0.05). Egg quality aspects such as yolk weight, egg weight, HU and yolk index were not differed significantly (P>0.05) among treatments.  A trend for lower yolk weight was observed in birds fed 10% linseed, where as the highest yolk weight percentage was recorded in control diet. There was no statistical difference among the different diets for yolk index. The results of the present trial suggested that feeding linseed to the laying hens has no detrimental effects on egg production and egg quality.
