This research investigates the effects of adding vitamin E, vitamin C, vitamin E+C, and alpha lipoic acid to feed rations for Japanese quails (Coturnix coturnix japonica) exposed to heat stress. The aspects studied were growth performance, carcass composition and breast meat characteristics. Five groups of quails, containing 50 birds each (250 Japanese quails: 150 female and 100 male) were used. The 21-days-old birds were fed for a period of 21 days, and they were kept in a controlled environment with a temperature of 34˚C between 08:00 and 17:00 and a temperature of 24˚C for the remaining part of the day. The five groups under study included: a control group without any additive (BS), a group fed diets with vitamin E (BSE), with vitamin C (BSC), with vitamin E+C (BSEC) and with lipoic acid (BSLA). The supplement additions to the diets did not affect the growth performance and carcass composition of the birds. The TBA (malonaldehyde) value of the BS group was significantly higher (P < 0.001) than in the other groups. L*, a*, and b* values in muscle samples, superficialis pectoralis muscle (SPM) and deep pectoralis muscle (DPM), were determined. In the samples from the SPM, the L* value of the BS group was higher than in the BSC group; the a* value of the BSE group was higher than in the BS group; and the b* value of the BSC group was higher than in the BS group (P < 0.05). In the samples from the DPM, the L* value of the BS group was higher than in the BSEC group (P < 0.05); the a* values of the BSE and BSEC groups were higher than in the BS group (P < 0.05); and the b* values of the BSC, BSEC and BSLA groups were higher than in the BS group (P < 0.01). In the microbiological analysis of meat, total aerobic mesophilic bacterial counts of the BS and BSE groups were higher than the counts in the BSC, BSEC, and BSLA groups (P < 0.01); coliform bacterial counts were higher in the BSE group than in the BSC group (P < 0.05); and lactic acid was higher in the BSE and BSEC groups than in the BSC and BSLA groups (P < 0.01). In conclusion, the supplemented antioxidants did not exhibit any significant effect on growth performance, but they significantly decreased lipid oxidation in the meat.

This study was conducted to determine the effects of dietary vitamin C (L-ascorbic acid) and vitamin E (a-tocopherol acetate) on lipid peroxidation status measured as MDA and serum triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), as well as some other serum metabolite and mineral concentrations of Japanese quails reared under heat stress (34º C). One hundred-eighty 10-day-old Japanese quails were randomly assigned to six treatment groups, three replicates of 10 birds each. Using a 2 × 3 factorial design, the birds received two levels of vitamin C (100 and 200 mg/kg of diet) or three levels of vitamin E (125, 250, or 500 mg/kg of diet). Greater dietary vitamin E and vitamin C resulted in a greater serum T3, T4, and TSH (p=0.001), but lower ACTH (p=0.001) concentrations. Serum concentrations of T4 and TSH increased to a greater extent by increasing dietary vitamin C when greater vitamin E levels were fed (interaction, p=0.001). Serum glucose, urea, triglycerides, and cholesterol concentrations decreased (p=0.001), while protein and albumin concentrations increased (p =0.001) when both dietary vitamin C and vitamin E were increased. Serum activities of SGOT and SGPT were not influenced by dietary vitamin C or vitamin E (p>0.43). However, serum activity of AP increased (p=0.001) by increasing both dietary vitamin C and vitamin E. Increasing both dietary vitamin C and vitamin E caused an increase in serum concentrations of Ca, P, K (p=0.001), Fe, and Zn (p=0.01) but a decrease in serum concentrations of Na (p=0.001) and Cu (p=0.01). Interactions between vitamin C and vitamin E were detected for Ca, P, Na, and K (p =0.001). Greater dietary vitamin C and vitamin E resulted in a greater serum and liver vitamin E, C, and A (p_0.05), but lower MDA (p=0.001) concentrations. Results of the present study conclude that supplementing a combination of dietary vitamin C (200 mg) and vitamin E (250–500 mg) offers a good management practice to reduce heat stress-related decreases in performance of Japanese quails.

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.

This experiment was conducted to evaluate the effects of vitamin C (L-ascorbic acid) and vitamin E (α-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°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 α-tocopherol acetate/kg of diet or 250 mg of L-ascorbic acid plus 250 mg of α-tocopherol acetate/kg of diet. Although feed consumption of the hens was similar (P > 0.05) among treatments, supplemental vitamin C and E significantly increased final body weight, egg production, and improved feed efficiency (P < 0.05). Egg weights were also greater (P < 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 < 0.05). Each dietary supplement of vitamin C and vitamin E improved the egg quality (P < 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 < 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.

Three experiments were conducted in a climatic chamber to determine the effects of vitamins D3 and C supplementation on performance, body temperature, and egg quality under thermoneutral temperature (24.8º to 27.0º C), a cyclic heat stress (26.2º C for 16 h and 32.1º C for 8 h) and a constant heat stress (30.0º to 32.0º C) for three weeks in each temperature. One hundred forty-four White Leghorn hens aged 31 weeks were used in a completely randomized design with a factorial arrangement of 3 x 3: vitamin D3 (2,500, 3,000, and 3,500 IU/kg) and vitamin C (0, 200, and 400 ppm), with a total of nine treatments with four replicates of four hens each. Parameters measured included feed intake (FI), feed:gain (FG), egg production (EP), egg weight (EW), egg mass (EM), rectal (RT) and dorsal temperatures (DT), percentages of albumen (AP) and yolk (YP), Haugh units (HU), yolk index (YI), shell percent (SP), shell thickness (ST) and egg specific gravity (ESG). Vitamin D3 influenced the parameters SP, ST, ESG and DT; vitamin C influenced YI, SP and ESG. There was no influence of environmental temperature only on HU. It was concluded that higher levels of vitamin D3 and 200 or 400 ppm of vitamin C can be improve eggshell quality and that heat stress impaired the main characteristics evaluated.
