This study was carried out to determine the effects of two different cage systems (enriched and conventional) and low and high stocking densities on performance, egg quality and egg shell microorganisms. In study, two different genotypes were used to native (Atak-S) and foreign (Lohmann) hens occurred of 864 hens used. As the cage system, the battery type was used in the conventional system and the enriched cage type was used in the alternative system. The results indicated that genotype and cage system significantly affected egg production and egg mass in the laying period (18-76 weeks). It was determined that Lohmann genotype and conventional cages had significantly higher egg production and egg mass in this period. It was seen that hens consumed significantly higher feed in enriched cages than in conventional cages, and were significantly better feed conversion ratio in low stocking density compared to high stocking density. The effects of genotype and cages system on the quality characteristics of eggs were found to be significant, and it was determined quality characteristics of Lohmann eggs were better (especially eggshell quality. In addition, it was understood that the internal quality of the eggs in the conventional cages and the external quality characteristics of the eggs in the enriched system were positively affected. The total numbers of microorganisms were determined to be higher on shell of eggs from enriched cages than conventional cages. The total numbers of microorganisms were higher in enriched cage eggs compared to conventional cage eggs. However, stocking density was not a significant effect on the microbial load of the eggshell.

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.

The present study was conducted to know the production and reproduction potentials, and egg quality characteristics of Nageswari duck under intensive management condition. Data were collected from a nucleus flock of Nageswari ducks that have been maintained from day old to 72 weeks of age at AI center, Bangladesh Agricultural University, Mymensingh, from May 2015 to October 2016. Irrespective of sex, the average live weight of ducklings at day old, 1st, 3rd, 5th, 7thand 9thweeks of age were observed to be 38.85±1.40, 99.06±2.93, 373.29±8.73, 650.31±11.26, 867.74±11.79 and 1076.11±16.34 g, respectively. There was a steady increasing trend observed in live weights for both drakes and ducks from 17thto 72 weeks of age. The average age of sexual maturity and weight were found 130±1.83 days and 1400.84±12.68g respectively. The average egg weight and annual egg production were 58.20±1.50g and 204.23±14.19 no’s, respectively. Hen day egg production was found 55.67±2.74% while the peak production was observed at 26th week of age. The estimated mean egg mass production (g/b/day), feed intake(g) during laying, feed conversion efficiency and performance efficiency index of Nageswari duck were 32.40±2.29, 154.85±2.27, 4.63±0.21 and 20.92±1.37, respectively in Nageswari duck. The external egg quality characteristics like shape index, egg breaking strength, shell thickness and membrane thickness were observed to be 74.59±0.61, 2.00±0.03 kg/cm2, 3.99±0.06 mm and 0.50 ± 0.02 mm respectively whereas, internal quality attributes such as albumen index, yolk index, yolk color score and Haugh unit were 8.89±0.29, 34.36±0.61, 8.42±0.28 and 86.29±1.06, respectively. In conclusion, the studied parameters of Nageswari duck provided some breed specific baseline information and year round actual production potentials of this genetic resource under intensive management condition that could be utilized for future conservation and breeding programs in Bangladesh.Bang.

Effects of dietary Garcinia kola meal (bitter kola) on the performance and egg quality characteristics of laying hens were investigated. Four layers diets were made such that diet T0 (control) contained no Garcinia kola meal while diets T2.5, T5.0 and T7.5 contained 2.5%, 5.0% and 7.5% Garcinia kola meal, respectively. Each diet was fed to a group of 30 laying hens at 30 weeks of laying life for 84 days, using completely randomized design (CRD). Each group was further sub-divided into three replicates of 10 hens each. The layers on T2.5 and T5.0 diets added significantly (P < 0.05) less body weight than those on T0 and T7.5 diets. There were no significant differences in their feed intake (P > 0.05). T2.5 significantly (P < 0.05) depressed hen-day egg production but enhanced egg weight. Feed conversion ratio (g feed/ g egg) was not affected by the treatments (P > 0.05). Egg quality indices (egg shape index, egg specific gravity, Haugh unit, egg shell thickness, albumen index and yolk index) were not affected by the treatments (P > 0.05). Egg shell index was significantly (P<0.05) enhanced by Garcinia kola meal. At 2.5% level, it significantly enhanced percent albumin and reduced percent yolk (P<0.05). Cost of egg production (N/kg eggs) was adversely increased as the level of Garcinia kola meal increased.

The goal of the present study was to evaluate the influence of increasing levels of dietary calcium on performance, egg quality, and the amount of calcium retained in the meat and excreted by Japanese quails at the final production. Four hundred 46-58-week-old Japanese quails were distributed in a completely randomized design consisting of five calcium level treatments: T1 = 2.95%, T2 = 3.25%, T3 = 3.55%, T4 = 3.85% and T5 = 4.15% calcium. The performance variables included feed intake (g bird-1 day-1), egg production (%), feed conversion by egg mass and per dozen eggs, egg mass (g), and viability. For egg quality, we assessed egg weight, percentage of albumen, yolk weight, percentage of shell, and shell thickness. We also evaluated the amount of calcium present in the meat and the amount of calcium excreted by quails. Increasing levels of calcium linearly influenced feed conversion, weight of yolk, and percentage of eggshell. Shell thickness increased up to the 3.85% calcium treatment. Calcium content of the meat differed among the quails; the quails fed the lowest level of calcium (2.95%) showed higher calcium content in meat, whereas calcium excretion increased with increasing levels of calcium in the diet. In conclusion, the addition of 3.85% of calcium in quail feed at the end of production improved eggshell quality, and maintained internal quality and performance within the recommended standards for the production phase tested in quails. Levels higher than 3.85% calcium negatively influenced the parameters analyzed.

The aim of this study was to investigate the effects of different levels of alfalfa meal on performance, egg quality, egg yolk cholesterol and hatchability parameters of quail breeders. In this trial a total of 90 Japanese quail breeders (30 males, 60 females), 10 weeks old was distributed 5 experimental groups randomly. Each experimental group consisted of 6 replicates of 3 quails (1 males, 2 females) in each. During the 12 weeks experiment period, birds were fed with 5 dietary groups based on corn and soybean meal and containing 0 (control), 10, 20, 40 and 80 g/kg alfalfa meal. Feed and water were offered ad-libitum throughout the experiment. The different dietary levels of alfalfa meal had no significant effect on body weight change, egg production, egg weight, egg mass, feed conversion ratio, egg shell breaking strength, egg yolk triglyceride, fertility, hatchability of fertile eggs or hatchability of eggs set. The feed intake was decreased with 10 or 20 g/kg alfalfa meal levels in the diet. The eggshell weight was best in quails fed 20 g/kg alfalfa meal, and the egg yolk cholesterol was the lowest in quails fed 40 g/kg alfalfa meal. According to the results of this study the addition of 40 g/kg alfalfa meal in laying quail diets decreased the egg yolk cholesterol levels without adverse effect on performance.

This experiment was carried with Japanese quails in the egg production phase with the objective of determining the requirements of digestible methionine + cystine (M+C) for higher production and egg quality. A total of 240 Japanese quails were distributed in a randomized complete block design. The basal diet was supplemented with different DL-methionine levels, corresponding to digestible methionine + cystine levels of 0.55, 0.61, 0.67, 0.73 and 0.79%. The characteristics analyzed were feed intake (g/quail/day), egg production (%), egg weight (g), egg mass (g/quail/day), feed conversion (dozen eggs/egg mass and kg feed/dozen eggs), egg shell (% and g), albumen (% and g), yolk (% and g) and specific gravity (g/cm³). The digestible M+C level for Japanese quails was 0.696% in the diet, corresponding to a daily intake of 186.7 mg/quail.

The present study determined, assessed and quantified the exogenous phytase on egg production and egg quality of spent hens. Ninety laying hens (ISA- Brown) received iso-energetic and iso-nitrogenous diet supplemented with 0, 0.05, 0.1, 0.15 and 0.2 % phytase and reared in cages. Each layer was fed 120g feed/day from 90 to 100 weeks of age. At the inception of the study the spent hen at the age of 90 weeks had an average egg production 65.21 %. Phytase addition in diet increased (p<0.05) egg production  (7.67, 12.17, 12.04 and 15.87 % higher than control group), egg mass output (5.5, 9.34, 7.65 and 12.72 % higher than that of control) and feed conversion, but it did not alter shell weight, shell thickness, shape index, albumen index, Haugh unit, per cent yolk and yolk color. It was concluded that reduced egg production of spent hen at older ages to some extent might have a relationship to decreased availability of phosphorus. The decreased egg production in hens at older ages could be corrected by adding appropriate phytase level in the diet. Thus, it may be possible to extend and prolonged productive life of spent hens by supplying exogenous phytase in diet. However, the effect of availability of phosphorus on egg production using larger population for a longer period may be performed to confirm the findings of the current study.

SUMMARY The aim of this study was to evaluate the effects of different forced-molting methods on the performance and quality of laying quail eggs. The experiment was conducted in a conventional shed for quails and lasted 115 days. 480 Japanese quails at an initial age of 52 weeks were used. The following treatments were evaluated: total feed fasting (control treatment); corn and soybean bran diet; high- zinc diet (7,300 ppm); wheat bran diet; and ground corn diet. A fully randomized experimental outline was used with 5 treatments and 4 repetitions. Each lot was formed by 24 quails with a total of 480 birds. Performance (production and egg weights, feed intake, feed conversion ratio per kg egg mass and per dozen eggs, viable eggs and egg viability) and egg quality (eggshell thickness and yield, specific weight and Haugh unit) were evaluated. Treatment differences were compared using the Scott-Knott test (5%). Wheat bran and high- zinc diets yielded poorer averages of egg production and feed conversion ratioper dozen eggs. Studied treatments had no influence on egg quality. Hence, we can conclude that corn- only or corn and soybean bran only feeds can be adopted as forced molting methods in Japanese quails instead of traditional fasting methods.

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.

A three months feeding trial was conducted to assess the effects of feeding varying levels of dietary protein on productive performance, egg quality characteristics and hatchability using 930 six weeks breeders quails. The birds were randomly divided into five dietary treatment groups of 186 birds, and were further replicated three times with 62 birds (50 females, 12 males) per replicate. They were fed five experimental diets containing either 18, 20, 22, 24 or 26% CP. Feed and water were provided ad libitum throughout the experimental period. The results obtained did not show significant effect (P>0.05) on final live weight, % change in body weight, feed conversion ratio, cost per dozen or crate of egg produced, hen-day-production, hen-housed production and peak egg production across the dietary treatments. However, significant differences (P<0.05) were observed for feed intake, age at peak production, egg weight and percent mortality across the dietary treatments. Dietary protein levels had no significant (P>0.05) effects on Haugh unit, egg shape index, percent egg shell, egg shell index, egg specific gravity and egg shell thickness. Significant differences (P<0.05) were observed across dietary treatments for % hatchability, fertility and chick weight at hatch. Chick weight at day-old increased with increase in the level of dietary protein. It was concluded that dietary protein level of 22%CP is required for optimum production, egg quality characteristics and reproductive performance of breeder quails in the tropics
