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.

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 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 study was conducted to investigate the phenotypic features, morphometry and production potentialities of indigenous dwarf chicken (IDC) of Bangladesh under intensive management condition. A total of 48 females and 12 males were collected from different districts and the experiment was performed at BAU Poultry farm for a period of 75 weeks. The predominant plumage and skin color were black and white, respectively. The average shank length, shank circumference and live weight (28 weeks) in adult males and females were 7.5 and 4.69 cm, 6.28 and 3.69 cm, and 1.77±0.38 and 1.10±0.077 kg, respectively. The reduction of live weight for dwarf male and female chickens relative to their normal shanked counterparts (NSC) at same age was 12.91 and 16.91%, respectively. Hen day egg production, average egg weight, average feed intake and FCR (feed conversion ratio) of IDC were recorded 37.43%, 38.25 g, 69.57g and 4.58, respectively. The average age and weight at sexual maturity were recorded as 166.53 days and 1093 g, respectively. IDC consumed 11.13% less feed than NSC during 1-20 weeks. Survivability of IDC up to 0-8, 1-23 and 24-75 weeks of age were found 97.25, 94.90 and 95.24%, respectively. The study reveal that IDC had relatively lower adult weight and consumed less feed without affecting egg production compared to NSC under intensive management condition and could be exploited its potentiality for development of mini layer under semi-scavenging system of Bangladesh.Bang.

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

Background and Aim: The use of antibiotics as growth promoters in the feed of poultry, has contributed to an increase in the antimicrobial resistance of foodborne pathogens worldwide. Hence, the development of new effective alternatives to antibiotics that do not hinder productivity is imperative. For this, the aim of the present study was to determine whether oregano essential oil (OEO) extracted from Lippia origanoides is a suitable alternative to growth-promoting antibiotics (GPAs) for improving the performance, egg quality, and intestinal morphometry of ISA Brown laying hens. Materials and Methods: A total of ninety-six 70-week-old ISA Brown laying hens were randomly assigned to four treatment groups with four replicates per treatment and six hens per replicate. The treatments consisted of four different diets that were formulated according to the nutritional requirements of the genetic line and the production phase with and without the addition of GPA and OEO: NC, which did not contain OEO or GPA; GPA, which included 50 ppm zinc bacitracin as a GPA; 80OEO, which included 80 ppm OEO and no GPA; and 150OEO, which included 150 ppm OEO and no GPA. Results: All of the OEO and GPA treatment groups had a better feed conversion ratio than the NC group. However, the addition of 150 ppm OEO to the diet improved the percentage egg production and egg mass, as well as the external and internal quality of the egg compared with the other treatments. In addition, both the 80OEO and 150OEO treatments improved the yolk color, shell thickness, and shell color, as well as parameters related to the intestinal morphometry compared with the NC group. Conclusion: The findings of this study indicate that 150 ppm OEO can be used as a substitute for GPA to improve the performance, egg quality, and parameters related to the intestinal morphometry of ISA Brown laying hens.

Two factorial trials, each including three commercial laying hybrids, were conducted to study the effects of a short laying rest on postrest performance of hens and on egg quality. A total of 1800 hens laying at 65% on an average (70 wks of age) were subjected to one of the following treatments: no rest (control, C) or feeding only whole-grain barley (WB) or fasting (F, Trial 1 only) until the rate oflay dropped to 0%, after which the birds were returned to the previous all-mash diet. The second laying period was six months. Egg production of the WB and F hens ceased within one week on an average and the birds were out of production for 10 days. Laying intensity during the second production period did not differ significantly between the treatments in each trial, but egg weight and daily egg mass production increased as a result of the rest treatments. The laying rest procedures reduced feed intake, improved feed efficiency and increased live weight significantly. Egg shell and albumen quality traits were significantly better in the laying rest groups than in the controls. Significant differences in performance and egg quality between the hybrids were mainly ascertained in Trial 2. The results suggest that a short laying rest is a feasible means of improving egg quality towards the end of the laying period. It can be accomplished successfully by feeding whole-grain barley.

The present study aimed to evaluate the effect of dietary Moringa oleifera (M. oleifera) leaves and/or seed powder on laying Japanese quail performance in terms of egg production, egg quality, blood serum characteristics, and reproduction. In total, 168 Japanese quails (120 hens and 48 males) at eight weeks of age in laying period were randomly distributed to four treatment groups, with six replicates per group and seven birds (five hens and two males) per replicate. The first group (G1) served as a control group, while G2, G3 and G4 groups were supplemented with M. oleifera leaves (ML) and M. oleifera seeds (MS) and their combination ((1 g/kg ML; 1 g/kg MS; and 1 ML g/kg + 1 MS g/kg (MSL), respectively). From the results, feed consumption, feed conversion ratio, egg weight, fertility and hatchability from fertile eggs, egg and yolk index, and Haugh unit were not affected by dietary treatments. However, egg production, egg mass, eggshell thickness, and hatchability were significantly increased and blood aspartate transaminase (AST) and urea decreased in the MS treatment. Both triglycerides and total cholesterol were reduced (p < 0.05) in all treatments with ML, MS, and MSL, with no significant differences in alanine aminotransferase (ALT), albumin, total protein, globulin, and A/G ratio among dietary treatment. Our results clearly indicated that the inclusion of M. oleifera seeds in Japanese quail diet significantly increased egg production and improved hatchability, along with some egg quality parameters, and also lowered some blood biochemical components.

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.

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.
