This study was carried out to determine the effect of a high level of aflatoxin B1 in laying hen diets, supplemented with deactivated and activated clinoptilolite, on inner and outer quality and aflatoxin B1 residues in eggs. Two experimental groups were formed and fed high aflatoxin B1 diets (965 ppb) containing deactivated and activated (450 ?C for 60 minutes) clinoptilolite (2% of diet) for 49 days. In the experiment, a total of 960 55-week-old Lohmann LSL (white) laying hens were used. Each group had 8 replicates and 480 hens. Egg weight, inner and outer egg quality parameters and egg aflatoxin B1 levels were determined in a total of 90 eggs collected on the 15th, 30th and 49th days of the experiment. Diets containing deactivated or activated clinoptilolite decreased aflatoxin B1 production in laying hen diets after incubation period of 15 days. Activation of clinoptilolite by heat treat?ment significantly reduced aflatoxin B1 level in eggs (p<0.05). In addition, the use of clinop?tilolite as an antifungal agent in the presence of high aflatoxin B1level in layer hen diets significantly increased the weight of eggs and significantly reduced the ratio of broken-cracked and dirty eggs (p<0.05). Chicken blood albumin, creatinine and calcium levels were higher in hens fed diet containing activated clinoptilolite (p<0.05). However, triglyceride and VLDL levels decreased significantly in the blood of these animals (p <0.05). In conclusion, the supplementation of hen diets containing high aflatoxin B1 with activated clinoptilolite improves production performance, egg quality and decreases aflatoxin B1 residue in the egg.

This study was conducted to appraise the effects on egg quality and production performance of laying hens when drinking water was supplemented with calcium (Ca) and magnesium (Mg). A total of 384 (64-week-old) Hy-line Brown laying hens were assigned at random to four treatments, which consisted of CON: unsupplemented drinking water; T1: drinking water + 2 mg/L Ca + 250 mg/L Mg; T2: drinking water + 4 mg/L Ca + 510 mg/L Mg /10 L; and T3: drinking water + 5 mg/L Ca and 760 mg/L Mg. The experiment lasted six weeks. Water intake increased linearly in week 1 with the rising levels of Ca and Mg in the drinking water. Increasing the Ca and Mg levels improved eggshell strength (week 2 (P =0.01), week 5 (P =0.01), and week 6 (P = 0.03), and eggshell thickness (week 6) (P =0.02) and reduced the rate at which eggs were broken (week 4) (P =0.01). The supplemental Ca and Mg did not affect egg production, egg weight, Haugh unit, albumen height, eggshell colour, and yolk colour compared with CON. Nor did they influence the Haugh unit and albumen height after storing for 1, 5, 10 and 15 days. In conclusion, adding Ca and Mg to the drinking water increased the thickness and strength of the eggshells.

Phosphorus Levels

The effects of diet type (wheat- or maize-based) and concentration of available phosphorus (AP; about 4, 3 and 2 g/kg) on the parameters of hen performance and egg quality as well as shell calcium (Ca) and phosphorus (P) contents were examined. Two experiments were carried out in which 240 and 120, respectively, older ISA Brown hens were housed in enriched cages. The interaction of diet type and AP concentration was ascertained for all evaluated characteristics except the amount of Ca and P deposited in shells in the first experiment. In the second experiment, the interaction of diet type and AP concentration was found for feed intake, egg weight, shell thickness and weight as well as the albumen quality parameters. Furthermore, Ca deposition in shells increased (P &lt; 0.001) with the wheat diet. Hens fed a maize-based diet (P &lt; 0.001) laid heavier eggs. The highest level of AP (4.1 g/kg) in the wheat-based diet significantly (P &lt; 0.001) decreased albumen height, albumen index and Haugh units (HU). These trends were the same in both experiments. The results indicate that 0.27% AP in wheat-based diet and 0.30% AP in maize-based diet are adequate for hens with the intake 115 g of feed with 3.5% of Ca without a negative impact on performance or egg quality.

The differences in egg production traits in six laying hen genotypes (brown-egg hens Bovans Brown, Bovans Sperwer, ISA Sussex; white-egg hen Dekalb White; laying hens with tinted shells Moravia Barred and Moravia BSL) and the interactions of genotype and oviposition on egg quality were evaluated. The genotype affected the laying rate (P ≤ 0.003), mean sequence length (P ≤ 0.001), and time of oviposition (P ≤ 0.001). The brown-egg genotypes laid eggs approximately 1 h earlier than the white-egg genotypes and approximately 2 h earlier than the tinted-egg genotypes. Egg shell strength was the lowest in tinted-egg genotypes (P ≤ 0.001) and declined with the time of oviposition (P ≤ 0.002). Egg shell percentage (P ≤ 0.011) and thickness (P ≤ 0.011) were affected by the interaction of genotype and oviposition. None of the effects affected egg weight; however, the proportion of egg components was significantly influenced by the interaction of genotype and oviposition. The study confirmed that the differences in the egg production and egg quality of various genotypes are associated with the laying pattern.

The experiment was conducted to evaluate the production performance and egg quality of laying hens supplemented with phytobiotics and magnetized drinking water. This experiment used 2700 gauss level in Magnetized Drinking Water (MDW). The phytobiotics had two form: the non-encapsulated phytobiotics (PTO) and encapsulated phytobiotics (EPTO). There were untreated water (control) and the treated water (MDW, PTO, PTO+MDW, EPTO, EPTO+MDW). The treatments were presented by 0.6% for each treatment. The result showed highly significant (p<0.01) improvement on feed conversion ratio (FCR) but no significant effect on other production performance variables including feed intake, hen day production (HDP), egg mass, and income over feed cost (IOFC). The results indicated a highly significant improvement (p<0.01) on egg weight and yolk cholesterol. There were no significant effects on shape index (SI), shell weight, shell thickness, Haugh unit (HU), albumen height, yolk weight, yolk index (YI), and yolk color of egg quality variables. It was concluded that the encapsulated form (EPTO and EPTO+MDW) had the best improvement on FCR and yolk cholesterol, on another hand the non-encapsulated form (PTO and PTO+MDW) increased the egg weight of laying hens

Vicia faba has considerable potential as a protein supplement for farm livestock in many parts of the world. The protein content varies depending on cultivar but has been reported to range from 230 - 390 g/kg (Garrido et al 1991) The extensive use of vicia faba in laying hen diets has been limited by the, presence antinutrients such as tannins, lectins and pyrimidine glucosides which have been reported to decrease protein digestibility (Lacassagne et al. 1988) and adversely affect egg production and quality parameters such as egg number and egg weight (Guillume et al 1977). The production of low tannin cultivars of vicia faba has increased interest in its use in poultry feeds and an experiment was conducted to investigate the effects on egg production and quality of inclusion of whole ground beans; cotyledons or hulls from one such low tannin cultivar ‘Toret’.

The research aimed to determine the characteristics and quality of egg of commercial laying hens fed ration supplemented with garlic (Allium sativum) powder. The research used Completely Randomized Design (CRD) with five treatments and four replicates (5 hens each) for a total of 100 brown laying hens strain MB 402. Garlic powder contained 24.62% crude protein, 38.81% fat, and 1.74% crude fiber. The treatments of garlic powder ration were 0, 2, 4, 6, and 8%. The treatments performed were dietary, with R0 = 100% based diet (BD); R1= 98% based diet (BD) + 2% garlic meal (GM); R2= 96% based diet (BD) + 4% GM, R3 = 94% based diet (BD) + 6% GM, R4 = 92% based diet (BD) + 8% GM. The study was conducted during eight (8) weeks. Collected data were quality, weight, shell weight, albumen weight and shell thickness of eggs. Data was analyzed with Analysis of Variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT). The results showed that 8% garlic powder ration increased weight and albumen weight of eggs. There were no significant effect of treatments in yolk weight, shell weight and shell thickness of eggs. Garlic powder supplementation on laying hen ration affected egg weight and albumen weight. The addition of garlic powder on laying hen ration of up to 4% increased egg weight. Albumen weight increased until garlic powder supplementation of up to 8%. It is recommended the use of 8% garlic powder supplementation on lying hen ration without negative effects on egg quality.

The aim of this paper is to present results achieved by adding dietary phytogenic additive (Biomin? P.E.P. 125 poultry) on production and quality of table eggs in the early stages of laying period in commercial Hy Line Brown hens. The experiment was conducted from 16 to 28 weeks of hens age. During the experimental period the following parameters were determined every week : egg production, percentage of second grade eggs and egg weight. The examination of egg quality was conducted at 21, 24, 26 and 28 weeks of hens age. Based on the obtained results we can conclude that the addition of dietary phytogenic additive induced an increase in egg production and egg weight and reduced the percentage of second grade eggs. Significant effects of phytogenic additive on some egg quality parameters were not established.

Canola and juncea meals (CM and JM) have been thoroughly evaluated in diets of white- but not brown-shell egg laying hens (BSLH). This study compared the effects of dietary CM, JM, or soybean meal (SBM) on production performance and egg quality of BSLH. Over 48 wk, 300 Lohmann Brown-Lite laying hens were fed diets containing SBM, 10% or 20% CM (CM-10 or CM-20), and 10% or 20% JM (JM-10 or JM-20), without (−E) or with (+E) a phytase/multicarbohydrase enzyme cocktail. Egg weight decreased with CM-20 inclusion compared with SBM (P = 0.027; SBM, 63.1a; CM-10, 61.8ab; CM-20, 61.1b; JM-10, 62.6ab; JM-20, 61.7ab; g egg−1). In a meal by enzyme interaction, enzyme inclusion decreased percent shell and egg specific gravity of only the hens fed CM-20 (P ≤ 0.008). Body weight decreased (P = 0.031; −E, 2135a; +E, 2078b; g hen−1) and feed efficiency was improved (P = 0.032; −E, 1.98a; +E, 1.95b; g feed g egg mass−1) when enzyme was included in the diet. Dietary treatment did not affect mortality (P > 0.05). All performance and quality parameters were within expected ranges; therefore, 20% CM and JM can be included in BSLH diets, and enzyme inclusion can be used to improve feed efficiency regardless of meal type fed.

Data penelitian dianalisis dengan uji-t untuk mengetahui perbedaan antar kelompok perlakuan. Hasil penelitian menunjukkan bahwa konsumsi air minum, konsumsi ransum dan konversi ransum secara statistik berbeda nyata. Konsumsi air minum pada perlakuan AG (286,57 ml/ekor/hari) lebih tinggi dari pada perlakuan ANG (264,24 ml/ekor/hari), demikian juga konsumsi ransum (98,82 g/ekor/hari vs 90,10 g/ekor/hari). Sedangkan konversi ransum pada perlakuan AG (2,71) lebih baik dari pada perlakuan ANG (3,18). Pada peubah kualitas telur hanya bobot telur yang menunjukkan perbedaan nyata. Bobot telur pada perlakuan AG (55,85 g/butir) lebih tinggi dari pada perlakuan ANG (54,18 g/butir). Kesimpulan dari penelitian ini adalah pemberian minum dengan AG mampu memperbaiki kinerja produksi ayam petelur, terlihat dari konsumsi air minum, konsumsi dan konversi ransum. Sedangkan pada kualitas telur hanya terlihat dari bobot telur.  (Performance and egg quality of laying hen given peat water and non peat water) ABSTRACT. The aim of this study was to evaluate the performance and egg quality of laying hens given peat water (PW) and non-peat water (NPW). This study used 30 laying hens strain lohman brown aged 15 months with commercial ration feeding. The study consisted of two groups of chickens with 15 chickens each. The first group was given PW and the second group was given NPW. The variables observed were water consumption, feed consumption, egg production and mass, FCR, egg weight, albumin and yolk index, egg shell thickness and haugh unit value. Data obtained were analyzed using t-test to determine the differences between treatment groups. The results showed that water consumption, feed consumption and FCR were statistically difference. The daily water consumption in PW treatment (286.57 ml/bird/day) was higher than in NPW treatment (264.24 ml/bird/day), as was ration consumption (98.82 g/bird/day vs 90.10 g/ bird/day). While the ration conversion in PW treatment (2.71) was better than that of NPW treatment (3.18). In the egg quality variable, only egg weight showed a significant difference. Egg weight in PW treatment (55.85 g/egg) was higher than in NPW treatment (54.18 g/egg). The conclusion of this experiment was the given peat water to laying hens was able to improve the production performance, indicated by water consumption, feed consumption and FCR. Meanwhile, the quality of eggs can only be seen from the egg weight.
