Three hundred and ten 12-week-old laying Japanese quails (Coturnixcoturnix japonica) from gray and white varieties (155 each) were randomly selected from the initial population and kept in individual battery cages. The measurements of growth and egg production were determined to derive residual feed intake (RFI). The relationship between RFI and egg quality, blood parameters, and carcass characteristics was also determined. The results indicated that the gray quails had significantly higher egg mass and lower broken eggs compared to the white quails. A significant increase of eggshell strength and shell percentage was found in eggs produced from gray quails compared to their white counterparts, although their shell thickness means weresimilar. The results of multiple regression analysis clearly identified a significant effect of metabolic body weight and egg mass for the computation of expected feed intake, rather than body weight gain, in both varieties of Japanese quails. A strong positive correlation between RFI and feed intake in both gray and white quail varieties was found. The same trend was also observed for feed conversion ratio (FCR). Therefore, including RFI in the selection criteria of Japanese quails in order to improve FCR under high environmental temperature is highly recommended.

The present study was conducted to evaluate the optimum level of dietary inclusion and the form of feeding sapu-sapu fish (SSF) as a single protein source for feed components of small holder Mojosari duck farming. A total of 180 twenty four wk-old laying ducks were fed with two forms (sun-dried and ground-fresh) and three levels of SSF (10, 20 and 30%) from 24 to 32 wk of age. Experimental diets were formulated containing 105.1; 141.5 and 177.9 g/kg crude protein and 3078; 3065 and 3052 kcal metabolizable energy (ME) /kg diet. Production performance and egg quality were measured. The form of SSF had a significant effect (P<0.0001) on feed intake, egg production, feed conversion, egg mass and egg number except final body weight. No significant effects (P>0.05) were found on all of the performance parameters measured due to feeding levels of SSF except feed intake and final body weight. The interaction of form and feeding level was significant (P<0.05) on egg and body weights. Low performance and egg quality were observed in the birds fed a diet containing the dried SSF. It can be suggested that local ducks required 20% SSF as a single protein source for maximum egg production (41.2%) and total egg number per wk (3.1 eggs/bird/wk) during 8 wk of rearing period. Egg quality can be improved by feeding the fresh SSF. However, due to be sufficiently better processing technique, the dried SSF would be potential to replace the common fish for laying ducks.

Effect Of Feeding

A trial was conducted to evaluate the requirement of digestible lysine at various protein levels in the diet of WLH layers (BV-300) from 25-44 weeks of age. Layers (528) were fed with diets containing two protein levels i.e. 13.36 and 15.78 % each with 5 % concentration variations of lysine (0.50, 0.55, 0.60, 0.65, and 0.70) and a control with 17 % CP and 0.70 % lysine. Each diet was fed to six replicates of eight birds. Egg production, feed intake, body weight were not influenced either by the concentration of lysine or by level of protein in diet. Increased (P d” 0.05) egg weight and egg mass were observed with increasing lysine in diets. Better feed efficiency was observed with increasing lysine concentration. It can be concluded that WLH layers require approximately 0.65% lysine with 13.36% CP or 0.63% lysine with 15.78% CP (i.e. 598.80 vs 570 mg/h/day) in diet.

A study was conducted in order to estimate the sodium requirements of Japanese laying quail (Coturnix coturnix japonica). In this study, we used 280 Japanese quails at 128 days of age, with an average weight of 9 ± 5.2 g, and an egg production rate of 82.3 ± 0.94%. An experimental design methodology was employed, completely randomized with five treatments and seven replications. Each replicate consisted of eight quails, with a total of thirty-five experimental units. The experimental diets were based on corn and soybean meal, and contained five different levels of sodium (0.08%, 0.12%, 0.16%, 0.20% and 0.24%). The diets were isocaloric and contained equal concentrations of amino acids, with an electrolyte balance of 250 mEq/kg. The parameters we evaluated were feed intake (g/quail/day); egg production per quail per day (%); egg weight (g); egg mass (g/quail/day); and feed conversion by egg mass (kg/kg) and per dozen eggs (kg/dz). In addition, we evaluated the composition of the eggs in terms of the absolute (g) and relative (%) mass of the yolk, albumen and eggshell. We also measured the body weight variation (g) and viability (%) of the quails. There were no significant effects (p>0.05) on the described parameters. No nutritional disorders occurred related to the level of inclusion of sodium in the diets. The inclusion of 0.08% sodium in the diet of laying Japanese quails was satisfactory to maintain egg production and quality without losses in feed intake or feed conversion.

The study was conducted at Bangladesh Livestock Research Institute to evaluate the productive and reproductive performances of 4 pure lines conserving for the production of next generation. A total of 2000 pedigree hatched day-old chicks were wing banded and reared up to 40 weeks of age. Data were kept on daily feed intake (g/bird/day), weekly body weight (g), age at sexual maturity (days), daily egg production (%) and egg weight (g). There were highly significant differences (p<0.01) in body weight at 38 weeks, age at sexual maturity, egg production up to 40 weeks and egg weight at 38 weeks of age among the treatment groups. There were no significant differences (P>0.05) in fertility, hatchability, dead in germ, sound chick and dead in shell percentage among the treatment except cull chicks where L1 showed the highest percent of cull chicks.  Egg production at 23-28 and 35-40 weeks of age differ significantly (p<0.01) except at 29-34 weeks of age (p>0.05). Significant variations for FCR observed at 35-40 weeks of age while it was non-significant (p>0.05) at 23-28 and 29-34 weeks of age. It is revealed that line-2 is superior in terms of egg production, age at sexual maturity and egg mass where line-1 was better in terms of FCR value. Considering the results it may be concluded that there are significant variations exists regarding egg production performances among the experimental pure lines, thus could be utilized successfully for the production of high yielding strains through proper breeding programme.

The aim of this study was to determine the effects of adding orange peel (PKY), lemon peel essential oils (LKY) and PKY+LKY (respectively 300, 300, 150+150 mg/kg) to laying quail diets on performance, egg internal and external quality parameters and hatchability parameters. The eight-week trial was conducted in 20 subgroups, with 4 treatment groups and 5 replications for each treatment, and a total of 120 Japanese quails at 10 weeks of age were randomly distributed, with 6 quails (4 females, 2 males) in each subgroup. Feed intake with the addition of LKY to the diet, egg production and egg mass with the addition of PKY + LKY decreased significantly compared to the control group, and the eggshell breaking resistance with the addition of LKY and PKY + LKY increased significantly compared to the control group. However, the addition of LKY, PKY and PKY+LKY to the diet did not affect hatchability and reproduction parameters. According to these results, the addition of 300 mg/kg PKY and 300 mg/kg (150+150) PKY+LKY to breeder quail diets had an effect on the increase of eggshell qualityi, although the performance was adversely affected.

The objective of this study was to evaluate different inclusion levels of distillers dried grains with solubles (DDGS) from corn in the diet of quails. A total of 210 japanese quails (Coturnix coturnix japonica) were distributed in a completely randomized design of five treatments and six replicates, with seven quails per experimental unit. The treatments used were: control feed; inclusion of 5, 10, 15 and 20% of DDGS. The variables assessed were: feed intake, feed conversion per dozen and egg mass, egg production, egg weight, specific gravity, yolk color and economic analysis. Data were analyzed by regression model and Dunnett’s test at 5% probability. For individual feed intake, laying rate, and feed conversion per egg mass, specific gravity and yolk color by color fan, there was effect caused by inclusion of DDGS (p < 0.05), but the other variables did not show significant difference. By Dunnett’s test, for feed intake, feed conversion per egg mass, specific gravity and digital colorimeter’s L parameter, there was effect (p < 0.05). As for economic analysis, DDGS presented low cost. It can be concluded that DDGS can be used in feed at a 20% level without impairing the performance and quality of quails eggs.

The objective of this study was to evaluate the effects of different tryptophan and digestible lysine ratios for growing Japanese quails (1 to 40 days of age) with repercussions on the early stage of production (41 to 110 days of age). A total of 1000 one day old Japanese quails were distributed at random, with five tryptophan and digestible lysine ratios, 10 replicates and 20 birds per experimental unit. A tryptophan- deficient basal diet was formulated with 1.48 g of digestible tryptophan /kg, corresponding to a ratio of tryptophan and lysine of 0.14. This basal diet was supplemented with five levels of L-tryptophan (98%), replacing glutamic acid corresponding to the tryptophan and lysine ratio of 0.14 (no supplementation); ratios of 0.16; 0.18; 0.20 and 0.22, being the diets isocaloric and isonitrogenous. The performance of the birds in the growing and egg laying phases was evaluated. Although body weight and weight gain until 40 days of age had increased (P<0,001) and feed intake in the egg laying phase had decreased (P=0,037) in a linear fashion, LRP was the one with the best adjustment for those parameters. The effect was quadratic for feed intake (P=0,0069), feed conversion (P=0,0032) and viability (P<0,001) of the birds in the growing phase.  A quadratic effect was found for egg production per bird housed at one day of age (P<0,001), weight gain at 110 days of age (P=0,039) and feed conversion per egg mass (P=0,046) in the laying phase. Intake of tryptophan increased (P<0,001) and egg production per housed bird in the laying phase linearly decreased (P<0,001) with the increase in the ratios between tryptophan and lysine. The digestible tryptophan and digestible lysine ratio is 0.18 (1.88 g of tryptophan/kg and 10.5 g of lysine/kg of diet), corresponding to an intake of 20.63 mg of tryptophan per bird per day, in the diet for growing, provides greater viability of birds in the growing phase and a satisfactory performance of Japanese quails in the laying phase.

Rice is the second largest cereal crop in the world and the by-products resulting from rice processing for human consumption are potential feedstuffs to compose poultry diets. In this sense, it was evaluated the influence of parboiled rice bran (PRB) in diets for Japanese quails in growing phase on the performance and digestibility, besides of residual effects and characteristics of egg quality in laying phase. A total of 324 Japanese quails with 7 days of age were distributed in a completely randomized design, with 6 treatments and 6 replicates of 9 birds. The treatments consisted of 6 isonutritives diets, being a control diet without PRB and the others containing 5, 10, 15, 20 and 25%. At the end of growing phase the birds were allotted in cages and fed the same diet without PRB at laying phase. At growing phase, the inclusion of PRB up to 5% promoted linear reduction in dry matter and gross energy digestibilities of diet; however a linear increase in metabolizable energy was noted. Feed intake, weight gain and final weight were reduced but not altering feed:gain ratio and body composition. At laying phase, the inclusion of PRB increased the age at first egg production but no influence was verified at age to reach 50% of egg production. No effect was verified at laying percentage, feed intake, weight and egg mass and feed:gain ratio. In economical evaluation, the inclusion of up to 25% of parboiled rice bran provided best economical indexes. The inclusion of PRB Japanese quails diets at growing phase can be recommended in levels up to 25%, without incurring future losses at laying phase.

The objective of this work was to evaluate the relationships of methionine plus cystine with lysine for Japanese quails in the laying phase. Thus, it was used 480 birds at initial age of 65 days, distributed in randomized block design with 6 treatments, 10 replicates and 8 birds per experimental unit. The treatments consisted of basal diet deficient in methionine plus cystine (0.65%), with 19.6% of crude protein and 2800 kcal of metabolizable energy/kg of ration, supplemented with six levels of DL-methionine 98% (0.116; 0.167; 0.218; 0.269; 0.320 and 0.371%), corresponding to methionine plus cystine with lysine ratio of 0.65, 0.70, 0.75, 0.80, 0.85 and 0.90, and the digestible lysine set at a suboptimal level of 1.00. The parameters studied were: feed intake, egg production per hen day, egg production per housed hen, commercial egg production, egg weight, egg mass, feed conversion per egg mass, feed conversion per dozen eggs, viability of birds, weight of the egg components (yolk, albumen and shell), percentage of components of eggs, diameter and height of the eggs and specific gravity. It was observed an increasing linear effect for feed intake, egg diameter, shell weight and percentage of yolk. For eggshell percentage, it was observed a decreasing linear effect. For the weight of the eggs, the best adjustment was obtained by using the Linear Response Plateau model. A quadratic effect was observed for egg mass, feed conversion per egg mass, egg production per hen day, egg production per housed hen, yolk weight, albumen weight and height of the eggs. The relationship of methionine plus cystine with lysine of 0.84 which corresponds to the consumption of 221.0 mg/bird/day of methionine + cystine provides better performance and satisfactory quality of Japanese quail eggs.
