The effects of humic acid on feed consumption, egg production, feed efficiency, egg weight and external and internal egg quality of laying hens were studied during feeding periods. A total of 180 (Hysex Brown) layers (36 weeks of age) were used in this experiment. There was one control and two experimental groups, each containing 60 hens and 4 subgroups. The experimental period lasted 16 weeks. At the end of the experiment, the supplementation of humic acid had a significant effect on feed consumption and feed efficiency. An increase in egg production was determined when humic acid was added to the diets at 30 g/t of feeds (91.70%) and 60 g/t of feeds (91.32%). There were no significant differences between the groups in egg shell thickness, egg shell breaking strength, yolk index, albumen index and Haugh unit. It can be therefore concluded that the dietary supplementation of humic acid at doses of 30 and 60 g/t feed can be used to improve egg production, egg weight and feed efficiency.

ABSTRAK. Penelitian ini bertujuan untuk mengevaluasi kinerja produksi dan kualitas telur ayam petelur yang diberi air gambut (AG) dan air non gambut (ANG). Penelitian ini menggunakan 30 ekor ayam petelur strain lohman brown umur 15 bulan dengan pemberian pakan ransum komersial. Penelitian terdiri dari dua kelompok ayam dengan jumlah masing-masing 15 ekor. Kelompok pertama diberi minum AG dan kelompok kedua diberi ANG. Peubah yang diamati adalah konsumsi air minum, konsumsi ransum, produksi dan massa telur, konversi ransum, bobot telur, indeks putih telur, indeks kuning telur, tebal cangkang telur dan nilai haugh unit. Data penelitian dianalisis dengan uji-t untuk mengetahui perbedaan antar kelompok perlakuan. Hasil penelitian menunjukkan bahwa konsumsi air minum, konsumsi ransum dan konversi ransum secara statistik berbeda nyata. Konsumsi air minum pada perlakuan AG (286,57 ml/ekor/hari) lebih tinggi dari pada perlakuan ANG (264,24 ml/ekor/hari), demikian juga konsumsi ransum (98,82 g/ekor/hari vs 90,10 g/ekor/hari). Sedangkan konversi ransum pada perlakuan AG (2,71) lebih baik dari pada perlakuan ANG (3,18). Pada peubah kualitas telur hanya bobot telur yang menunjukkan perbedaan nyata. Bobot telur pada perlakuan AG (55,85 g/butir) lebih tinggi dari pada perlakuan ANG (54,18 g/butir). Kesimpulan dari penelitian ini adalah pemberian minum dengan AG mampu memperbaiki kinerja produksi ayam petelur, terlihat dari konsumsi air minum, konsumsi dan konversi ransum. Sedangkan pada kualitas telur hanya terlihat dari bobot telur.  (Performance and egg quality of laying hen given peat water and non peat water) ABSTRACT. The aim of this study was to evaluate the performance and egg quality of laying hens given peat water (PW) and non-peat water (NPW). This study used 30 laying hens strain lohman brown aged 15 months with commercial ration feeding. The study consisted of two groups of chickens with 15 chickens each. The first group was given PW and the second group was given NPW. The variables observed were water consumption, feed consumption, egg production and mass, FCR, egg weight, albumin and yolk index, egg shell thickness and haugh unit value. Data obtained were analyzed using t-test to determine the differences between treatment groups. The results showed that water consumption, feed consumption and FCR were statistically difference. The daily water consumption in PW treatment (286.57 ml/bird/day) was higher than in NPW treatment (264.24 ml/bird/day), as was ration consumption (98.82 g/bird/day vs 90.10 g/ bird/day). While the ration conversion in PW treatment (2.71) was better than that of NPW treatment (3.18). In the egg quality variable, only egg weight showed a significant difference. Egg weight in PW treatment (55.85 g/egg) was higher than in NPW treatment (54.18 g/egg). The conclusion of this experiment was the given peat water to laying hens was able to improve the production performance, indicated by water consumption, feed consumption and FCR. Meanwhile, the quality of eggs can only be seen from the egg weight.

This study was conducted to appraise the effects on egg quality and production performance of laying hens when drinking water was supplemented with calcium (Ca) and magnesium (Mg). A total of 384 (64-week-old) Hy-line Brown laying hens were assigned at random to four treatments, which consisted of CON: unsupplemented drinking water; T1: drinking water + 2 mg/L Ca + 250 mg/L Mg; T2: drinking water + 4 mg/L Ca + 510 mg/L Mg /10 L; and T3: drinking water + 5 mg/L Ca and 760 mg/L Mg. The experiment lasted six weeks. Water intake increased linearly in week 1 with the rising levels of Ca and Mg in the drinking water. Increasing the Ca and Mg levels improved eggshell strength (week 2 (P =0.01), week 5 (P =0.01), and week 6 (P = 0.03), and eggshell thickness (week 6) (P =0.02) and reduced the rate at which eggs were broken (week 4) (P =0.01). The supplemental Ca and Mg did not affect egg production, egg weight, Haugh unit, albumen height, eggshell colour, and yolk colour compared with CON. Nor did they influence the Haugh unit and albumen height after storing for 1, 5, 10 and 15 days. In conclusion, adding Ca and Mg to the drinking water increased the thickness and strength of the eggshells.

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.

An experiment was conducted to determine the effects of feeding diets containing 0, 5, 10, and 15% ground raw rapeseed to three replicates of 14 laying hens each. Isocaloric isonitrogenous diets were fed for a 28-day experimental period and performance and egg quality parameters were measured. Egg production was depressed at the two higher levels of rapeseed inclusion but was not affected at the 5% level of inclusion. Haugh unit, albumen height, and shell deformation were not affected significantly (P > 0.05) but egg weight decreased progressively as rapeseed inclusion increased. Feed consumption was significantly depressed (P < 0.05) at the 15% level of rapeseed and slightly reduced at the other levels.

Two 280-day trials, each involving 468, 22-week-old caged commercial egg-strain pullets were conducted to Compare millet and sorghum grain as the main source of energy in laying diets. Diets containing 59.2 and 0, 41.0 and 24.0, 31.2 and 36.3 and 0 and 72.5% of sorghum grain and pearl millet, respectively, were studied in both trials The diets containing millet supported egg production, egg weight, feed conversion and egg shell thickness equivalent to those of the all-sorghum diet. Except in Trial 1, feed consumption of the pullets fed the millet-containing   diets was not significantly lower than that of the pullets fed the all-sorghum diet. Haugh unit values tended to decrease as the level of millet was decreased. Feeding millet at a level as high as 72.5% Of the diet may have adverse effects on egg specific gravity and haugh units

The differences in egg production traits in six laying hen genotypes (brown-egg hens Bovans Brown, Bovans Sperwer, ISA Sussex; white-egg hen Dekalb White; laying hens with tinted shells Moravia Barred and Moravia BSL) and the interactions of genotype and oviposition on egg quality were evaluated. The genotype affected the laying rate (P ≤ 0.003), mean sequence length (P ≤ 0.001), and time of oviposition (P ≤ 0.001). The brown-egg genotypes laid eggs approximately 1 h earlier than the white-egg genotypes and approximately 2 h earlier than the tinted-egg genotypes. Egg shell strength was the lowest in tinted-egg genotypes (P ≤ 0.001) and declined with the time of oviposition (P ≤ 0.002). Egg shell percentage (P ≤ 0.011) and thickness (P ≤ 0.011) were affected by the interaction of genotype and oviposition. None of the effects affected egg weight; however, the proportion of egg components was significantly influenced by the interaction of genotype and oviposition. The study confirmed that the differences in the egg production and egg quality of various genotypes are associated with the laying pattern.

Two experiments with nine strains of Single Comb White Leghorn hens were conducted to compare laying house performance of hens given a diet of uniform protein content or a phase-feeding diet in which protein content was reduced from 156 to 148 and then to 140 g/kg at 273 and 414, or 273 and 384 days of age. Performance criteria were egg production, feed and protein intake, egg, quality, egg weight, mortality and body weight. Phase-feeding allowed reductions of 4.2 and 4.3% in protein consumption without reducing egg production, mortality or, except in one strain, body weight. There was an increase of 0.5% in feed consumption, but feed cost was reduced by 1.3%. Phase-feeding increased Haugh units by 0.3% and decreased specific gravity of eggs in one experiment, decreased percent visibly-cracked eggs in the other experiment and had no effect on percent blood spots. Depending on strain, phase-feeding had a variable effect on egg weight in exp. 1 but had no effect in the second experiment. Key words: Phase-feeding, protein utilization, egg production, hen

This experiment was carried out to determine the effects of using L-carnitine and humate alone or in combination in quail diets on laying performance, egg traits and blood parameters. A total of 280 Japanese quails aged 10 weeks, divided into one control group and three treatment groups, were used. The diets of the first, second and third treatment groups were supplemented with 100 mg L-carnitine/kg, 1.5 g humate (Farmagülatör® Dry Plus)/kg and 100 mg L-carnitine + 1.5 g humate/kg, respectively. The experimental period lasted 16 weeks. The addition of L-carnitine and sodium humate alone or in combination did not significantly affect body weight, feed consumption, egg production, feed conversion ratio, mortality, egg-shell thickness, egg yolk index and the percentages of egg-shell, albumen and yolk. Egg weight increased (P < 0.001) with L-carnitine supplementation. The values of egg albumen height (P < 0.05), egg albumen index (P < 0.01) and egg Haugh unit (P < 0.05) were increased with humate supplementation. Egg cholesterol content and blood serum parameters were not affected by the supplementation of L-carnitine with or without humate. The results in this study demonstrated that L-carnitine supplementation increased egg weight while humate addition increased egg albumen index and egg Haugh unit of laying quails. However, the combined administration of L-carnitine and humate did not have any significant effects on the parameters measured.

The aim of this paper is to present results achieved by adding dietary phytogenic additive (Biomin? P.E.P. 125 poultry) on production and quality of table eggs in the early stages of laying period in commercial Hy Line Brown hens. The experiment was conducted from 16 to 28 weeks of hens age. During the experimental period the following parameters were determined every week : egg production, percentage of second grade eggs and egg weight. The examination of egg quality was conducted at 21, 24, 26 and 28 weeks of hens age. Based on the obtained results we can conclude that the addition of dietary phytogenic additive induced an increase in egg production and egg weight and reduced the percentage of second grade eggs. Significant effects of phytogenic additive on some egg quality parameters were not established.

Lowman Brown hens, 37 – week – old were used to study the effect of dietary inclusion of 10 and 20% cocoa husk meal (CHM) at the expense of maize on hen performance and egg quality. The trial was conducted for 10 weeks. Egg production (EP), egg weight (EW), egg mass (EM), feed consumption (FC), and feed efficiency (FC) were cost/kg egg, shell weight, percentage shell and yolk colour index. Inclusion of 10 and 20% CHM in laying hen diets had no significant effect (P <0.05) on EP, EM and FE. However, FC was high appeared to be compensated for by increased egg weight. Shell weight and percent shell were not affected by dietary treatment while the 20% CHM diet increased yolk colour index. Feed cost/kg egg was lowered by feeding the test diets. The present study has shown that laying hens can tolerate and produce eggs economically on diets incorporating up to 20% CHM.
