The objective of this work was to evaluate the effects of parboiled rice whole bran (PRWB) inclusion in laying diets for Japanese quails, on their performance, egg quality, and economic viability. A total of 448 17-week-old quails were weighed and distributed in a completely randomized design with seven treatments and eight replicates of eight birds each. A control diet (no PRWB) and six diets, containing 5, 10, 15, 20, 25, and 30% of PRWB, were tested. The increasing levels of PRWB did not affected nutrient digestibility coefficient, dietary energy use, feed intake, egg production, egg weight, egg mass, and the economic viability indices. However, there was a linear decrease in egg shell percentage, specific weight, and yolk color. The inclusion of up to 30% PRWB in the diet allows nutrient utilization and performance similar to those obtained by the control group, and it is economically viable.

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.

One hundred and twenty (100♀ + 20♂) 30-weeks-old dual-purpose breeding hens of Gimmizah strain were housed in individual cages in a semi-open house. Birds were distributed randomly into five treatments of 20♀ + 4♂. The 1st treatment was fed a control (unsupplemented) diet (17.5% CP and 11.4 MJ per kg diet) containing 0.10 mg Se/kg (low level). The 2nd, 3rd, 4th and 5th treatments were fed the control diet supplemented with 0.15 and 0.30 mg Se/kg from inorganic (sodium selenite) and organic (selenomethionine, as Se-yeast Selplex&reg; Alltech, Nicholasville, USA) sources, respectively. The total concentration of Se in experimental diets was 0.25 (medium level) and 0.40 ppm (high level). Feed and water were provided ad libitum throughout the experimental period (30&ndash;50 weeks of age). Different Se levels of the organic and inorganic form and their interaction did not significantly (P &gt; 0.05) affect egg production percentage, and most of egg quality traits. Egg weight and egg mass significantly (P &lt; 0.002) increased and the feed conversion ratio (FCR) significantly (P &lt; 0.04) improved due to Se supplementation compared with hens fed the control diet. Piped embryos and spleen percentage significantly (P &lt; 0.05) decreased due to Se supplementation. In addition, the level of organic and inorganic Se and their interaction significantly (P &lt; 0.0001) decreased the plasma cholesterol concentration. Tibia Ca and P percentages and yolk selenium concentration significantly (P &lt; 0.03; P &lt; 0.0001 and P &lt; 0.0001, respectively) increased due to Se supplementation and the greatest increase was recorded by a group fed diet with the high level (0.40) of organic Se. The duodenal and intestinal mucosa of the ileum was negatively affected by the high level of inorganic Se while chickens fed the organic form showed less toxic effects in hepatic and splenic tissues than those receiving the inorganic form. In conclusion, the organic and inorganic Se supplementation at 0.15 and 0.30 mg/kg diet, which corresponded to a dietary level of 0.25 and 0.40 mg/kg diet, improved the productive and reproductive performance of Gimmizah breeding hens. A decrease in plasma total cholesterol and an improvement in the bone mineralization were observed. The level of 0.25 mg/kg diet of organic Se was adequate to enrich eggs, which may be recommended for practical application and which would improve the consumer health benefit.

Significant Difference

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.

The Impact

Laying hens require substantial quantities of calcium (Ca) to maintain egg production. However, maintaining recommended dietary Ca through inclusion of limestone may impede nutrient digestibility, including that of other minerals. It was hypothesized that providing a separate source of dietary Ca in the form of limestone grit would preserve Ca intake of hens offered diets containing suboptimal Ca concentrations. Furthermore, the impact of dietary phytase at a “superdosing” inclusion rate on the voluntary consumption of limestone grit was evaluated. One hundred and forty-four laying hens (19 weeks of age) were assigned to one of six dietary treatments in a 3 × 2 factorial arrangement comprising three dietary Ca concentrations (40, 30, and 20 g/kg) and ±dietary phytase (3500 FYT/kg diet) on an ad libitum basis for six weeks. Limestone grit (3.4 ± 1.0 mm) was provided to all hens ad libitum. Hens offered diets containing phytase consumed significantly less limestone grit p = 0.024). Egg weight, rate of lay, and egg mass were unaffected by dietary treatment (p > 0.05). Egg shell weight % (p < 0.001), shell thickness (p < 0.001), and shell breaking strength (p < 0.01) decreased in line with dietary Ca levels. In summary, dietary superdosing with phytase reduced the consumption of a separate limestone source in individually housed, early lay ISA Brown hens. Egg shell quality variables but not egg production worsened in line with lower dietary Ca levels.

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 evaluate the effects of vegetable glycerin on performance and egg quality of red-egg layers in the second production cycle. A total of 252 Hy-Line Brown layers weighing 1.919 ± 0.095 kg, at 90 weeks, were used in a completely randomized design with six treatments and seven birds per replication. The experiment lasted 84 days. Treatments consisted of a control diet (no glycerin) and five diets with increasing levels of vegetable glycerin (2, 4, 6, 8, and 10%). The following variables were evaluated: feed intake (g/bird/day); egg production (%); egg weight (g); egg mass (g/bird/day); conversion per egg mass (kg kg) and per dozen eggs (kg/dz); percentages of albumen, yolk, and shell; eggshell thickness (mm); and egg specific gravity. (Y = 67.69 + 54.23X, R2 = 0.78) and egg mass (Y = 44.84 + 42.87X, R2 = 0.66) improved linearly with the glycerin levels. A quadratic effect was observed (Y = 114.11 + 336.96 X – 3,169.6 X2, R2 = 0.52) on feed intake. In conclusion, glycerin can be used to partially replace corn in diets for layers in the second production cycle at inclusion levels of up to 10%.

The study was conducted to determine the effect of antiprolactin drug (Bromergon®) and Peppermint (Mentha piperita L.) on broodiness, laying performance and egg quality in indigenous hens. The effect of modulation of prolactin concentration on egg production, sequence length and inter sequence pauses were studied by analyzing the oviposition records. Total sixty indigenous laying hens (30-40 weeks of age), were assigned for treatment with peppermint solution and Bromergon®. Sixty laying hens were randomly divided into 4 groups (A, B, C and D) and each group remained 15 hens. Group A was kept for control, Group B was treated with bromocriptine (Bromergon® SANDOZ) orally @ 640 ?g per bird per day, Group C with 50% peppermint solution @ 10 g per bird orally and Group D was with peppermint and Bromergon® combined at previous dose. Over the course of trial, incremental dietary peppermint (Group C) significantly (p?0.05) increased egg production, body weight of treated indigenous hens than other groups. Egg shell percentage, thickness and haugh unit of hens fed diets supplemented with peppermint were greater than that of hens fed the control diet. However, peppermint supplementation did not influence other egg quality characteristics like albumen and yolk percentages and albumen height. The treated birds had comparatively longer sequences and fewer pauses. It is concluded that the physiological pauses occur during ovulatory sequences can be disrupted effectively using Bromergon® and peppermint. Prolactin levels modulated which may interfere with follicular recruitment and subsequent oviposition thereby improves egg laying potential of the indigenous hens.Asian J. Med. Biol. Res.

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.

In this study, 160 73-week-old laying hens (HyLine W-36) were used to investigate the changes in production performance and egg quality parameters of aged laying hens after injection of different doses of growth hormone (GH) and a fixed dose of testosterone (Ts). The hens were weighed individually, placed in laying cages and then randomly assigned to four treatments with four replicates of 10 birds each, in a completely randomised design. The experiment was started at the 75th week and lasted until the 82nd week of age. The treatments were: 1: injection of 100 µL distilled water (control group), 2: injection of 500 µg Ts/kg liveweight + 50 µg GH/kg liveweight, 3: injection of 500 µg Ts/kg liveweight + 100 µg GH/kg liveweight and 4: injection of 500 µg Ts/kg liveweight + 150 µg GH/kg liveweight. In this study, ovulation rate (egg production percent), egg mass and feed intake were significantly higher in Treatment 3 than the control group (P < 0.05), and in Treatment 4, feed conversion ratio was significantly higher than for the other experimental groups (P < 0.05). In addition, the birds in Treatment 3 showed greater egg weight, albumen height, eggshell weight, eggshell density and eggshell weight per surface area than the control group (P < 0.05). In Treatment 3, egg length significantly increased compared with Treatments 1 and 4 (P < 0.05), and in Treatments 2 and 4, shell breaking strength was significantly lower than for the control group (P < 0.05). In conclusion, our results showed positive effects of GH and Ts administration on egg quality parameters and production performance in aged laying hens. Taken together, in the present study Treatment 3 was found more effective in improving egg quality and production performance of the old laying hens.
