The objective of this study was to determine the effect of dietary calcium levels on productive and reproductive traits of European male quail (Coturnix coturnix). A total of 60 European male quail, at 35 days of age, weighing 248.9g ± 8.1g were distributed in a completely randomized experimental design with five calcium levels (1.5, 2.0, 2.5, 3.0 and 3.5%), and 12 replicates per treatment (one bird each replicate). The experimental period was 35 to 70 days of age. At 70 days of age, the parameters of male productive traits assessed were: feed consumption, calcium consumption, weight gain and body weight of birds. The reproductive traits analyzed were: hatchability and fertility of eggs. Early, intermediate and late embryonic mortality were also evaluated. The diet containing 3.16% of calcium provides higher percentage of hatched eggs and did not show a negative effect on productive performance of European quails.

Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (p > 0.05). Adjusted feed conversion for control (1.23) was less than red (1.27; p = 0.001) and green (1.26; p = 0.009), with blue (1.25; p = 0.056) tending to be different during the experimental period. In Trial 2, there were no treatment effects on average body weight, feed consumption, and adjusted feed conversion during this study (p > 0.05). Body weight gain between d 1 to 14 for purple (490.78 g/bird) was more than orange (467 g/bird; p = 0.013) and yellow (461 g/bird; p= 0.004), with control (474 g/bird; p = 0.052) tending to be different. Results indicate that these feed colors had some, albeit limited, influence on broiler performance parameters.

ABSTRAKPenggunaan acidifier baik organik atau sintetis dapat meningkatkan optimalisasi nutrien di dalam saluran pencernaan.  Optimalisasi nutrien diharapkan dapat meningkatkan performa ternak khususnya puyuh. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan dua macam acidifier terhadap performa puyuh fase grower. 100 ekor unsexed puyuh (Coturnix coturnix Japonica) fase grower umur 14-40 hari digunakan dalam penelitian yang menggunakan rancangan acak lengkap dengan lima perlakuan dan empat ulangan. Bahan pakan yang digunakan adalah jagung kuning, dedak, konsentrat puyuh komersil, sari belimbing wuluh, dan asam sitrat sintetis. Perlakuan yang dicobakan terdiri dari perlakuan kontrol (P0), penggunaan 0,3% asam sitrat sintetis (P1), penggunaan 0,25% sari belimbing wuluh (P2), penggunaan 0,6% asam sitrat sintetis (P3), dan penggunaan 0,5% sari belimbing wuluh (P4). Variabel yang diamati adalah konsumsi ransum, pertambahan bobot badan dan konversi ransum mingguan. Penggunaan sari belimbing wuluh memiliki konsumsi pakan yang lebih rendah  (P<0,05) pada minggu pertama dibanding kontrol dan asam sitrat sintetis.  Penggunaan asam sitrat sintetis meningkatkan pertambahan bobot badan pada minggu pertama (P<0,05). Penggunaan asam sitrat sintetis nyata dapat menurunkan konversi pakan minggu ke tiga dan empat dibanding kontrol dan asam organik belimbing wuluh. Kesimpulan penelitian ini yaitu penggunaan sari belimbing wuluh sebagai acidifier belum menunjukkan perbaikan performa yang signifikan sedangkan penggunaan asam sitrat sintetis memiliki performa yang lebih baik dibanding perlakuan kontrol dan penggunaan sari belimbing wuluh.Kata kunci: acidifier, asam sitrat, belimbing wuluh, puyuh fase growerABSTRACTThe organic and synthetic acidifiers could improve the optimization of nutrients utilization in the quail digestive tract. Furthermore, the optimization of nutrients is expected to improve quail performance. This study was aimed to determine the effect of using two types of acidifiers (Averrhoa bilimbi juice and synthetic citric acid) on the grower phase of quail performance. Total of 100 unsexed quails (Coturnix coturnix japonica) grower phase aged 14-40 days were used in this research and designed as a completely randomized design of five treatments and four replications. Feed ingredients used were yellow corn, rice bran, commercial quail concentrate, Averrhoa bilimbi juice (organic acidifier), and synthetic citric acid. The treatments consisted of control (P0), 0.3% synthetic citric acid (P1), use of 0.25% Averrhoa bilimbi juice (P2), use of 0.6% synthetic citric acid (P3), and use of 0.5% Averrhoa bilimbi juice (P4). The variables observed were weekly feed intake, body weight gain, and feed conversion. The result showed that utilization of Averrhoa bilimbi juice has lower feed consumption (P<0.05) in the first week compare to control and synthetic citric acid, and synthetic citric acid utilization increases body weight gain in the first week (P<0.05). The use of synthetic citric acid significantly reduces feed conversion in the third and fourth weeks compared to control and organic acid groups. The conclusion of this study is the utilization of Averrhoa bilimbi juice as an acidifier has not shown significant improvements in quail performance. The use of synthetic citric acid has a better performance compared to control and Averrhoa bilimbi juice utilization.Keywords: acidifier, organic acidifier, citric acid, growing quail

Growth performance of commercial brown layer chicks (Shaver 579; n = 408) was studied in an open-sided house by feeding layer starter and layer grower diets during 0-17 weeks of age. The experimental period was divided into three phases: Phase I (0-4 weeks), Phase II (5-7 weeks) and Phase III (8-17 weeks). Both growth and feed consumption closely followed the standard data except during 10, 11, 12 weeks of age when the birds had to face some stresses. The target body weight was 1.4 kg which was achieved at proper age (17 weeks) by consuming feed almost similar to standard amount. Compensatory growth of chicks occurred during the later stage of growing period. The flock uniformity was 80% at 17 weeks. Livability of chicks was found to be excellent (99.3%) during the experimental period (0-17 weeks). It is suggested that despite some stresses, commercial brown layer chicks may achieve body weight and uniformity close to breeder’s standards when reared in an open-sided house.

Tibia Ash

A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to different cereals-soybean meal based diets on broiler performance and tibia ash. Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Supplemented phytase had beneficial effects on broiler performance. It significantly increased body weight gain (P &lt; 0.0003) and feed consumption (P &lt; 0.0361) by 6 and 7% in comparison with the control groups, respectively. No influence on feed conversion ratio and tibia ash was detected. Both body weight gain and feed intake were also significantly influenced by different cereals (P &lt; 0.0001 and 0.0348, respectively). The increasing dietary calcium level resulted in a significant increase in body weight gain (P &lt; 0.0024) and tibia ash (P &lt; 0.0016). Effects of 500 and 1 000 PU/kg were not statistically different between themselves. &nbsp;

Egg Weight

The aim of this study was to determine the effect of the genetic groups (three of local quails different with feather color, which are white, black and brown) and the egg weight (three classes of eggs are heavy, medium and light) and the interaction between them on productive performance during the growth phase (0-6 weeks of age). Eggs were individually weighed and graded into three groups: heavy (11.5-12.4g), medium (10.5-11.4g), and light (9.5-10.4g) inside each genetic group. The results of the statistical analysis showed a significant effect (p?0.05) of the genetic group (feather color), egg weight and their interaction on the productive performance during the total breeding period.The brown birds had significantly higher values of body weight, weight gain, carcass characteristics and better feed conversion ratio in all analyzed weeks. The birds which hatched from heavy eggs showed higher value of body weight, weight gain, carcass characteristics, feed consumption and better feed conversion ratio. Brown birds which hatched from heavy eggs had higher value of body weight, weight gain and carcass characteristics, while brown birds which hatched from medium eggs had better feed conversion ratio. We can therefore consider brown quail as the best for fattening purposes

Abstrak. Puyuh (Coturnix coturnix japonica) merupakan jenis unggas yang paling populer selain ayam dan itik di Indonesia yang diminati peternak unggas. Namun kendala utama dalam perkembangan puyuh yaitu kurang tersedianya bibit puyuh hasil persilangan dengan struktur breeding yang jelas sehingga dikhawatirkan terjadinya inbreeding. Sehingga perlu dilakukan penelitian persilangan (Cross breeding) puyuh Hybrid dengan Coturnix coturnix japonica terhadap pertumbuhan turunannya. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh persilangan puyuh Hybrid terhadap pertumbuhan, konsumsi pakan, pertambahan bobot badan dan umur dewasa kelamin turunannya. Hasil penelitian menunjukkan bahwa persilangan puyuh Hybrid dengan Coturnix coturnix japonica tidak berpengaruh nyata (P0,05) terhadap konsumsi pakan, pertambahan bobot badan, konversi pakan dan umur bertelur pertama turunannya. Namun dari hasil persilangan jantan Coturnix coturnix japonica dengan betina Hybrid memperlihatkan bahwa angka konversi pakan cenderung lebih efisien dan umur bertelur pertama lebih cepat.Response The Growing Consumption Woof and Adult Of Genders Age Which is Resulted by  Crosswise Mating Of Hybrid Quail  With Coturnix coturnix japonicaAbstract. Quail (Coturnix coturnix japonica) is the most popular type of poultry besides chickens and ducks in Indonesia that are favored by poultry farmers. But the main obstacle in the development of quail is the lack of availability of quail seeds from crosses with a clear breeding structure that is feared to occur inbreeding. So it is necessary to do a hybrid quail cross breeding study with Coturnix coturnix japonica on its derivative growth. The purpose of this study is to determine the effect of Hybrid quail crosses on growth, feed consumption, body weight gain and adult age of hereditary sex. The results showed that Hybrid quail crossing with Coturnix coturnix japonica had no significant effect (P 0.05) on feed consumption, body weight gain, feed conversion and age of first laying eggs. However, the results of Coturnix coturnix japonica male Hybrids with Hybrid females show that feed conversion rates tend to be more efficient and the age of first laying is faster.

Restricted Feed Intake

Two experiments were conducted to measure some of the effects of varying the length and the degree of feed restriction of confinement-reared pullets on laying-house performance. In general, increases in the length of time of restriction were followed by an increase in the number of days required to reach 50 per cent production, an increase in the initial egg size (first 8000 eggs), and a decrease in body weight at either 21 or 22 weeks of age. Feed restriction, in most cases, changed the pattern of egg production so that the birds came into production later than full-fed birds but subsequently "peaked" at a higher rate of production and maintained a higher rate of production for the remainder of the experimental period. Restricting the feed intake of the growing pullets resulted in a substantial feed saving during the growing period, but had no measurable effect on feed consumption during the laying period.

This study was carried out to investigate the effect of different body weight groups (light (L) = 1 400–1 500; medium (M) = 1 500–1 600 and heavy (H) = 1 600 < g) on performance and egg quality traits of Lohmann hens, 24 weeks of age, in different laying periods. A total of 288 Lohmann White layers were allocated randomly to three groups with respect to live weight, each consisting of 24 replicated cages as subgroups, comprising four hens. The study period lasting for 60 weeks was investigated as four different age periods (first period = 24–40 weeks; second period = 40–54 weeks; third period = 54–68 weeks; fourth period = 68–84 weeks). Differences in the initial live weight at the beginning of experiment among the groups continued to the end of experimental period. Considering the egg production, differences among the groups were not significant (<I>P</I> > 0.05) during the experimental period. Egg weight was determined to be lower in the group with low body weight (64.58 g) than in medium (64.97 g) and heavy hen groups (66.30 g). Differences in feed intake and feed conversion ratio among the groups were found significant, and the mean values were 123.93, 127.48 and 130.67 for feed consumption (g/day); 2.23, 2.28 and 2.27 for feed conversion ratio. Except for the feed conversion ratio, the effect of weight groups by age period interaction on performance parameters was significant (<I>P</I> < 0.01). The effects of body weight on shell strength, shell thickness and yolk index were not significant during the experimental period. However, different body weight groups significantly affected shape index, yolk colour, albumen index and Haugh unit parameters. Shell strength, yolk colour and yolk index values were affected by weight groups by age period interaction. In conclusion, Lohmann White hens in the light group in a uniform flock had higher egg production and lower feed conversion ratio values than those of other weight groups.
