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 < 0.05) with the OEO diet than in the control. The SY diet decreased egg production and the OEO diet decreased egg mass (P < 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 < 0.05). Serum uric acid was lower with diets containing Se than the control diet (P < 0.05). Glutathione peroxidase activity was highest with SY and SY + OEO diets and lowest with the OEO diet (P < 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 < 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.

Pakan merupakan salah satu faktor yang berpengaruh terhadap performa reproduksi induk ikan bandeng. Ketersediaan pelet komersial yang spesifik untuk pemeliharaan induk bandeng hingga kini belum ada sehingga perlu dilakukan pengembangan pakan untuk menghasilkan performa reproduksi yang lebih baik. Penelitian ini bertujuan untuk meningkatkan produksi dan kualitas telur induk bandeng melalui aplikasi bahan pengkaya pada pakan. Penelitian dilakukan di unit pembenihan skala lengkap Desa Banyupoh dan Desa Sanggalangit, Bali Utara. Jumlah induk yang digunakan adalah 165 ekor yang dipelihara dalam dua buah bak volume 100 m3 (di Desa Banyupoh) dan 100 ekor yang dipelihara dalam dua buah bak volume 100 m3 (di Desa Sanggalangit). Perlakuan yang digunakan adalah pakan komersial dengan penambahan bahan pengkaya (pakan uji) dan tanpa penambahan bahan pengkaya pakan (pakan kontrol). Bahan pengkaya berupa emulsi yang terdiri atas lesitin, minyak cumi, minyak ikan, minyak jagung, vitamin E, dan vitamin C yang dicampur dalam pakan dengan dosis sebesar 120 g/kg pakan. Pakan diberikan secara at-satiation dengan frekuensi 2-3 kali sehari. Penelitian berlangsung selama 10 bulan. Parameter yang diamati meliputi frekuensi pemijahan, produksi, dan kualitas telur. Hasil penelitian menunjukkan bahwa penggunaan bahan pengkaya dalam pakan mampu meningkatkan frekuensi pemijahan induk dengan rerata sebanyak lima kali/bulan di unit pembenihan skala lengkap Desa Banyupoh dan empat kali/bulan di unit pembenihan skala lengkap Desa Sanggalangit, serta dapat meningkatkan produksi telur masing-masing sebesar 102% dan 56% dibandingkan pakan kontrol. Teknik penambahan bahan pengkaya pada pakan dapat diterapkan pada pemeliharaan induk bandeng untuk mendukung produksi telur dan frekuensi pemijahan yang baik.Feed is one of the factors affecting the reproduction performance of milkfish broodstock. Hatcheries use mostly commercial pellets to feed broodstock despite that it is not a natural feed for milkfish. Thus, the food has to be enriched to maintain or improve the spawning performance of milkfish broodstock. The purpose of this study was to improve spawning performance of milkfish broodstock through the application of enriched-formulation feed. The study was conducted at two milkfish hatcheries in Banyupoh and Sanggalangit villages, North Bali. The number of broodstock used at Banyupoh village hatchery were 165 ind reared in two 100 m3concrete tanks. In the hatchery at Sanggalangit Village, 100 fish were reared in two 100 m3 concrete tanks. The feed enrichment formulation used a mixture of lecithin, squid oil, fish oil, corn oil, vitamin E, and vitamin C. The feed enrichment formulation was prepared in emulsion form and mixed with 120 g/kg dosage of feed. As a control, the feed used was without enrichment formulation. The feeding frequency was 2-3 times per day to satiation. The experiment was carried out for 10 months. The parameters observed included egg production, egg quality and spawning frequency. The results showed that the enriched feed had increased the spawning frequency of broodstock up to five times/month at the hatchery in Banyupoh and four times/month at Sanggalangit hatchery. Egg production also had increased to 102% (Banyupoh) and 56% (Sanggalangit) compared to the control feed. This feed enrichment formulation has the potential in broodstock milkfish rearing to improve the egg production and spawning frequency.

The objective of this study was to obtain enriched eggs with low cholesterol content. Forty-eight laying hens (strain Dekalb Warren) aged 72 weeks were distributed into six treatment groups as follows: 1) Laying hens fed diet without Sauropus androgynus leaf extracts (SALE), fish oil and vitamin E (P0) as the control; 2) Laying hens were fed diet with 27 g SALE/kg diet, but without fish oil (P1); 3) Laying hens were fed diet with 27 g SALE/kg diet, 1.5% fish oil (P2); 4) Laying hens were fed diet with 27 g SALE/kg diet, 1.5% fish oil and 60 mg vitamin E/kg diet (P3); 5) Laying hens were fed diet with 27 g SALE/kg diet, 3% fish oil (P4); 6) Laying hens were fed diet with 27 g SALE/kg 3% fish oil and 60 mg vitamin E/kg diet (P5). Experimental results showed that the treatments affected (P <0.05) egg production, thick eggshell, egg white height, yolk color, the odor of eggs after the split (P <0.05). It was shown that the treatments had no effect on the contents of protein, fat, β-carotene of eggs but affected the contents of cholesterol and vitamin E of eggs. In conclusion, the treatments improved egg quality and increased egg Vitamin E but reduced egg cholesterol.

This experiment was conducted to evaluate the effects of vitamin C (L-ascorbic acid) and vitamin E (&alpha;-tocopherol acetate) on egg production, egg quality, lipid peroxidation status (measured as MDA), and some serum metabolites in laying hens (Hy-Line) maintained at a low ambient temperature (6&deg;C). One hundred and twenty laying hens (18-wk-old) were divided into four groups, 30 hens per group. The laying hens were fed either a basal diet or the basal diet supplemented with either 250 mg of L-ascorbic acid/kg of diet, 250 mg of &alpha;-tocopherol acetate/kg of diet or 250 mg of L-ascorbic acid plus 250 mg of &alpha;-tocopherol acetate/kg of diet. Although feed consumption of the hens was similar (P &gt; 0.05) among treatments, supplemental vitamin C and E significantly increased final body weight, egg production, and improved feed efficiency (P &lt; 0.05). Egg weights were also greater (P &lt; 0.05) in hens supplemented with the combination of vitamin C and E than that of hens supplemented either vitamin or no vitamin (control). Haugh unit did not change upon each vitamin supplementation, but the combination of the vitamin supplement yielded a higher Haugh unit (P &lt; 0.05). Each dietary supplement of vitamin C and vitamin E improved the egg quality (P &lt; 0.05) resulting in a greater specific gravity, thicker egg shell, and heavier egg shell weight. Separately or as a combination, supplemental vitamin C and E decreased MDA, glucose, cholesterol, and triglyceride concentrations (P &lt; 0.05). Results of the present study showed that supplementing vitamin C and vitamin E, particularly as a combination, improved the performance of cold-stressed laying hens, offering a potential protective management practice in preventing cold stress-related losses in performance of laying hens. Results of the present study also indicated that the effects of vitamin C and vitamin E are additive.

Background and Aim: Copper (Cu) is a vital mineral involved in various physiological and biochemical processes, growth, and productivity of animals and birds. Birds can absorb only a small fraction of Cu and most is excreted, contaminating soil and aquatic environment which is toxic for microorganisms, plants, animals, and humans. This study evaluated the possibility of use of organic and nanoparticles sources of Cu to reduce supplementation level without compromising the performance of breeder hens. Materials and Methods: A total of 224 Swarnadhara breeder hens were divided into seven treatment groups having four replicates in each. The basal diet (control) containing 20 ppm inorganic Cu (100% of standard recommendation) and six test diets containing 20, 15, and 10 ppm (100, 75, and 50% of standard recommendation) from Cu organic source, and 15, 10, and 5 ppm (75, 50, and 25%) from Cu nanoparticles (Cu-NP), were prepared and offered to respective treatment groups for a duration of 20 weeks. Results: The hen day egg production, hen housed egg production, feed conversion ratio egg mass, albumen index, yolk index, total fat content, and color score were not affected by the source and inclusion level of Cu. The feed intake was significantly (p<0.05) lower at 15 ppm and egg weight was significantly (p<0.05) higher at 10 ppm Cu-NP supplemental level, but was non-significant in other treatment groups compared to control. The body weight gain were significantly (p<0.05) higher at 20 ppm organic and 15 ppm Cu-NP inclusion. The egg shape index and Haugh unit were significantly (p<0.05) lower at 10 and 15 ppm of Cu-NP inclusion level, respectively. The shell thickness was improved (p<0.05) at 20 and 15 ppm organic and 15 and 10 ppm Cu-NP inclusion level. The egg fertility rate was shown to be significantly (p<0.05) higher at 20 ppm organic Cu inclusion group, but the hatchability based on total number of eggs set improved (p<0.05) at 20 and 15 ppm organic Cu inclusion level while all treatment groups were comparable to control. The hatchability of fertilized egg and chick's quality significantly (p<0.05) improved, while embryonic and chick mortality after hatching before-sorting was significantly (p<0.05) reduced at 15 ppm of Cu-NP inclusion group. Conclusion: It was concluded that the inorganic Cu can be replaced with 50% of organic or 25% of nanoparticles form of Cu without jeopardizing the breeder hens' productivity, egg quality characteristics, hatchability, and progeny.

Laying Performance

Two hundred and forty laying hens were fed diets supplemented with vitamin C and selenium (Se). Vitamin C was added at 0 or 200 mg/kg, and Se was added as sodium selenite or selenized yeast at 0.3&nbsp;mg/kg. The feed intake and egg production were measured, and egg quality parameters were determined. Supplementation of the basal diet with Se significantly increased the laying performance; however, vitamin C significantly decreased feed intake and egg production. Vitamin C increased vitamin E concentration in the yolk. Both selenite and Se-enriched yeast increased the vitamin E concentration in the yolk and the Se concentration in the yolk and albumen. The oxidative stability of yolk lipids was improved in hens fed diets supplemented with sodium selenite, but not in those fed diets supplemented with Se-yeast. After 28 days of storage, however, the beneficial effect of selenite on lipid stability ceased. The supplementation of the basal diet with vitamin C significantly worsened the oxidative stability of yolk lipids, indicating that vitamin C acted as a pro-oxidant. Thus, vitamin C increased the laying performance and influenced some traits of egg quality. The combined supplementation of vitamin C and Se did not prove to be successful.

This study was conducted to determine the effect of cottonseed meal (CSM) incorporated into laying rations in place of soybean meal (SBM) at different ratios on yield traits. The birds began to lay at 6th week, 180 female and 45 male quails were used in laying period experiment. Birds were fed with rations containing 20% CP and 3000 Kcal/kg ME up to 20-week age (Laying period). CSM as a substitute, five different rations of the protein content (0, 30, 58, 86 and 100%) for SBM to basal diets based on corn-soybean meal were used. The results showed that there were no differences in terms of egg yield traits, cumulative feed consumptions and viabilities during the laying period. The highest dry shell rate and shell thickness were obtained from 5th group and 1st group, respectively. As a result, adding CSM instead of SBM in laying period were no significantly differences in terms of egg production and egg quality in laying period.
