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

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.

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.

Abstract This research aims to study and analyze the effect of adding turmeric flour (Curcuma domestica Val) in the rations on the performance of 70 weeks old Isa Brown strain of laying hens. The research method used in this study was an experimental method with a completely randomized design (CRD) step with five treatments and four replications. The number of chickens used was as many as 40 laying hens. The treatments given to the sample were P0 = feed without giving turmeric flour (control), P1 = feed with 0.3% turmeric flour, P2 = feed with 0.5% turmeric flour, P3 = feed with 0.7% turmeric flour and treatment P4 = feed by giving turmeric flour 0,9%. The results showed that giving turmeric flour in the rations of the Isa Brown strain of laying hens affected chicken performance and egg quality. This research concludes that giving turmeric flour a percentage of 0.7% in Isa Brown’s 70-week old laying hens is the best for ration consumption, Hen Day Production, egg weight, feed conversion, and egg quality: Haught Unit, yolk egg color, yolk egg index, grading egg and egg mass. Based on the haugh unit value, all eggs produced are still in the AA grade category

The present study was developed using 864 Hy-Line W36 laying hens (42 to 58 weeks of age) with a randomized experimental design in a 4x3 factorial arrangement, with five replicates and 12 birds per experimental unit and 4 evaluation periods of 28 days each. The digestible lysine levels studied were 0.675%, 0.743%, 0.811% and 0.879%, and the digestible threonine levels were 0.542%, 0.596% and 0.650%. The performance and egg quality was evaluated. There were no significant effects on the egg production, specific gravity, albumen and yolk percentage and total solids in albumen and yolk for birds submitted to the different dietary digestible lysine and threonine levels. There was significant interaction between these amino acids on the egg shell percentage and Haugh unit in fresh eggs. There was a decreasing linear effect on the feed intake with increase of digestible lysine level. Egg weight, egg mass and feed conversion demonstrated a quadratic effect with the increase of the digestible lysine level with the best results in the diets with 0.754, 0.772 and 0.795% of digestible lysine, respectively.

With the development of a large-scale and intensive production industry, the number of laying hens in China is rapidly increasing. Oils, as an important source of essential fatty acids, can be added to the diet to effectively improve the production performance and absorption of other nutrients. The present review discusses the practical application of different types and qualities of oils in poultry diets and studies the critical effects of these oils on production performance, such as the egg weight, feed intake, feed conversion ratio (FCR), and various egg quality parameters, including the albumen height, Haugh units, yolk color, and saturated/unsaturated fatty acids. This article reviews the effects of different dietary oil sources on the production performance and egg quality of laying hens and their potential functional mechanisms and provides a reference for the selection of different sources of oils to include in the diet with the aim of improving egg production. This review thus provides a reference for the application of oils to the diets of laying hens. Future studies are needed to determine how poultry products can be produced with the appropriate proper oils in the diet and without negative effects on production performance and egg quality.

AbstractChicken eggshell (ES) waste is a rich source of calcium carbonate (CaCO3); however, the potential of ES as dietary calcium (Ca) in old laying hens has not been explored. This study compared the effects of feeding limestone, cockle shell, oyster shell, fine ES, and coarse ES as the sole Ca source on production performance, egg quality, blood biochemical constituents, and tibia characteristics in old laying hens. A total of 450 ISA-Brown laying hens at 73 wk of age with similar egg production rate (EPR) were randomly assigned to 5 treatment groups (90 hens/group, 9 hens/replicate) for 7 wk. Dietary treatment groups comprised a corn-soybean meal based diet containing different Ca sources: (i) limestone (LS; < 2 mm and 2–4 mm mixed in the ratio of 3:7) as control, (ii) cockle shell (CS; 1–4 mm), (iii) oyster shell (OS; 3–16 mm), (iv) ES fine particles (ESF; < 1 mm), and (v) ES coarse particles (ESC; 3–5 mm). Results indicated that dietary inclusion of coarse ES particles significantly increased average egg weight (P < 0.001) and daily egg mass (P < 0.05), and decreased feed conversion ratio (P < 0.001) as compared with the other treatments. However, no significant differences in EPR, feed intake, cracked egg proportion, and mortality were observed among the dietary treatments (P > 0.05). Notably, the use of ESF led to a lower proportion of cracked eggs than ESC (P < 0.05). ESC fed hens produced the heaviest eggs whereas CS fed hens produced the lightest (P < 0.001); the particle size of ES also affected the egg weight (P < 0.05). The eggs from OS and ESC fed hens showed a greater albumen height in comparison to eggs from CS group (P < 0.05); but no significant difference was observed among the LS, OS, ESF, and ESC groups (P > 0.05). The yolk color was darker in the eggs of group ESF as compared with other dietary groups (P < 0.01). However, no significant effects on Haugh units and shell properties were observed among the treatments (P > 0.05). The blood biochemistry results were not affected by the dietary Ca (P > 0.05) except for lower levels of high-density lipoprotein percentage (HDL %) in OS and ESC fed hens (P < 0.05). The tibia characteristics including weight, length, width, and breaking strength did not differ among the dietary groups (P > 0.05). However, the ESC and OS fed hens showed higher tibia bone mineral density (BMD) than the other groups (P < 0.001). In conclusion, coarse ES as a sole Ca source had beneficial effects on the production performance, egg quality, and tibia BMD in old laying hens.

Nutritional evaluation of Delonix regia seed meal (DRSM) as an alternative energy feed ingredient in replacement of maize was carried out using one hundred and thirty-five (135) black Harco laying hens at twenty weeks old. Five experimental diets were formulated with 0 (60% Maize + 0% DRSM), 25 (45% Maize + 15% DRSM), 50 (30% Maize + 30% DRSM), 75 (15% Maize + 45% DRSM) and 100% (0% Maize + 60% DRSM) replacement of maize with DRSM weight for weight, designated as D1, D2, D3, D4 and D5 respectively. The experimental birds were randomly assigned to 5 experimental diets in a Completely Randomized Design. There were 3 replicates of 9 birds each. The feeding trial lasted for 84 days during which data were collected for 70 days with the first 2 weeks to allow the birds to acclimatize. Performance, egg quality and haematology of the experimental birds were monitored. The hen day production (HDP), egg weight, egg mass, feed conversion ratio (FCR), percentage yolk weight, albumen weight and packed cell volume (PCV) differed significantly (P < 0.05) across the dietary treatments. The HDP (%) reduced from 69.67 (D1) to 57.33 (D2), 44.33 (D3), 29.00 (D4), and 17.33 (D5). The egg mass, 38.68g (D1) reduced to 12.80g (D5). The lowest egg weight (55.26g) of the control (D1) increased to 73.94g (D5); and FCR from 2.82 (D1) to 9.23 (D5). The percentage yolk weight reduced while the percentage albumen increased with increasing substitution of DRSM for maize in the diets. Egg yolk colour improved with DRSM inclusion in the diets. The PCV values (%) were 25.20 (D1), 29.58 (D2), 28.33 (D3), 28.67 (D4), and 28.61 (D5). The optimum economic dietary inclusion of DRSM in place of maize for layers is 25% that is 45% Maize + 15% DRSM (D2); with DRSM improving the egg quality (increasing egg weight, percentage albumen and yolk colour score; and reducing the percentage yolk weight) of the experimental birds.     L'évaluation nutritionnelle de la farine de graines de Delonixregia (le 'DRSM') comme ingrédient d'alimentation énergétique alternative pour le remplacement du maïs a été effectuée à l'aide de cent trente-cinq (135) poules pondeuses harco noires à l'âge de vingt semaines. Cinq régimes expérimentaux ont été formulés avec 0 (60% Maïs + 0% DRSM), 25 (45% Maïs + 15% DRSM), 50 (30% Maïs + 30% DRS 75 (15% Maïs + 45% DRSM) et 100% (0% Maïs + 60% DRSM) remplacement du maïs avec poids DRSM pour le poids, désigné comme D1, D2, D3, D4 et D5 respectivement. Les oiseaux expérimentaux ont été assignés au hasard à 5 régimes expérimentaux dans une conception complètement randomisée. Il y avait 3 répliques de 9 oiseaux chacun. L'essai d'alimentation a duré 84 jours au cours duquel les données ont été recueillies pendant 70 jours avec les 2 premières semaines pour permettre aux oiseaux de s'acclimater. La performance, la qualité des œufs et l'hématologie des oiseaux expérimentaux ont été surveillées. La production de jour de poule (le 'HDP'), le poids d'oeuf, la masse d'oeuf, le rapport de conversion d'alimentation (le 'FCR'), le poids de jaune de pourcentage, le poids d'albumen et le volume emballé de cellules (PCV) ont différé sensiblement (P < 0.05) entre les traitements diététiques. Le HDP (%) de 69.67 (D1) à 57.33 (D2), 44.33 (D3), 29.00 (D4) et 17.33 (D5). La masse d'œufs, 38,68 g (D1) réduite à 12.80 g (D5). Le poids le plus bas des œufs (55,26 g) du contrôle (D1) est passé à 73.94 g (D5);fcr de 2.82 (D1) à 9.23 (D5). Le pourcentage de poids jaune réduit tandis que le pourcentage albumen a augmenté avec la substitution croissante de DRSM pour le maïs dans les régimes. La couleur du jaune d'œuf s'est améliorée avec l'inclusion du DRSM dans les régimes alimentaires. Les valeurs pcv (%) 25.20 (D1), 29.58 (D2), 28.33 (D3), 28.67 (D4) et 28.61 (D5). L'inclusion alimentaire économique optimale du DRSM à la place du maïs pour les couches est de 25%, soit 45% de maïs + 15% de DRSM (D2); avec DRSM améliorant la qualité des œufs (augmentation du poids des œufs, pourcentage d'albumen et de la couleur du jaune; et réduction du pourcentage de poids jaune) des oiseaux expérimentaux

ABSTRACT: This study was done to determine the best value of the total electrolyte balance (BET) concerning the variables of performance and egg quality of the laying hens. We investigated 240 Hy-Line Brown laying hens, of 30 to 46 weeks of age, adopting the completely randomized experimental design, which included five treatments (1000, 1250, 1500, 1750 and 2000 μeq / kg), 8 repetitions and 6 birds per unit. The performance and quality of the birds’ eggs were evaluated in the different treatments. The results were subjected to the analysis of variance and, wherever significant effect was noted, the regression equations were estimated, taking into account the electrolyte balance (μeq / kg) as a concomitant variable, applying the SAS statistical program (2001). The consumption, production, and feed conversion variables by dozen eggs, final bird weight, egg density, yolk color, Haugh Unit, albumen weight, shell weight, and egg weight, were found to be unaffected by the experimental BET values. The values of the feed conversion per egg mass, yolk weight and uniformity were affected by the different BETs. The electrolyte balance values showing minimum feed conversion, higher yolk weight, and better uniformity were, respectively, BET = 1400, 1330, and 1250 in μeq / kg of loads at the different temperatures. From the regression equations, the value indicated was BET=1390 for the 30- to 46-week-old laying hens. The electrolyte balance of the diet was found to affect the laying hens in terms of performance and egg quality.

SUMMARY In order to evaluate the performance and egg quality of quails on different time feeding, One hundred ninety two Japanese quail (Coturnix coturnix japonica) at 24 weeks of age were distributed in a completely randomized design with two replications and twelve treatments eight birds each. The treatments consisted of two different times of feeding at 6h and 16h. The performance was evaluated by the feed intake (g/bird/day), egg production (%), egg mass (g), feed conversion per egg mass (kg/kg ), feed conversion per dozen eggs (kg/dz) and viability (%). The egg quality was evaluated by the eggshell thickness (mm), percentage of albumen, yolk percentage and average egg weight (g). The feeding time at 16h favored the performance of Japanese quails at 26 and 34 wk of age considering egg production, egg mass and average egg weight. Thus, it is recommended to feed the quails at times that coincide with the highest egg laying intensity, which ranges from 16 to 19h.

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.
