This study aimed to assess the effect of stocking density of 10, 12, 14, and 16 birds m?2 on performance, carcass and cut yields, productivity, and bone development of broiler chickens Cobb 500®. The experimental design was completely randomized design with four treatments (stocking densities) and four replications. The assessments were performed weekly at 1, 7, 14, 21, 28, 35, and 42 days. The best live weight result was found at a density of 10 birds m?2 in the period from 1 to 7 days. No effect of density was observed on feed intake and weight gain. From 1 to 14 days, the best live weights were found at densities of 10, 12, and 14 birds m?2, in addition to a higher feed intake at densities of 10 and 12 birds m?2. Weight gain was better at a density of 10 birds m?2, showing no differences from densities of 12 and 14 birds m?2. In the period from 1 to 21 days, live weight and weight gain were higher at densities of 10, 12, and 14 birds m?2. The highest feed intake was observed at a density of 10 birds m?2, which showed no difference from the density of 14 birds m?2. A difference (P < 0.05) was observed for live weight, weight gain, and feed intake of animals reared at densities of 10, 12, and 14 birds m?2 for the phases from 1 to 35 days and the total phase from 1 to 42 days of bird age when compared to 16 birds m?2, which presented lower performance. However, feed conversion of 1-7, 1-14, 1-21, 1-35, and 1-42 days and carcass and cut characteristics showed no significant differences for all treatments. On the other hand, productivity was higher in the treatments with 14 and 16 birds m?2, but without difference between each other. No interaction (P > 0.05) was observed between stocking density and age for the assessed bone parameters. Similarly, no difference (P > 0.05) was observed for bone development of broiler chickens reared at different stocking densities for the studied parameters. Thus, the increased density of 10 or 12 birds m?2 to 14 birds m?2 has no influence on zootechnical performance, carcass and cut yields, and bone development, but increases broiler chicken productivity reared in a conventional shed without air conditioning.

This study was conducted to determine the effects of inorganic selenium (sodium selenite) and organic selenium (selenomethionine) supplementation on growth and viability of juvenile humpback grouper (Cromileptes altivelis). The experiment was designed as a completely randomized design with eight treatments and three replications. The treatment being tested was source and dosages of selenium ie., inorganic selenium (sodium selenite) supplementation with dosages of 0.5, 1, 2, and 4 mg Se/kg diet and organic selenium (selenomethionine) with dosages of 1, 2, and 4 mg Se/kg diet. Another treatment was unsupplemented selenium. Juveniles humpback grouper at an initial average length of 6,39±0,41 cm and body weight of 4,49±0,65 g were reared in 90×40×35 cm3 aquaria and fed artificial diet (pellet) two times daily (08.00 and 16.00) at satiation. Fishes were reared for 40 days at a stocking density of 12 fish per aquarium on sea water with salinity of 30–31 ppt and temperature of 28–29 °C. The results of this study showed that the source of selenium supplementation (inorganic or organic) affected growth performance, glutathione peroxidase (GPx) enzyme activity, and blood profiles of the experimental fish. Generally, it was found that selenomethionine supplementation resulted in better fish performance than sodium selenite. In sodium selenite supplementation, survival declined with the increased dosages of Se in the diet, and the supplementation at dosage of 0,5 mg Se/kg diet showed a toxic effects. Histopatological test showed that there were damage in livers, kidneys, and intestines of fish supplemented with sodium selenite from 0.5 to 4 mg Se/kg diet. On the contrary, supplementation of selenomethionine up to 4 mg Se/kg did not show any signs of toxicity and the survival was on 86.11 to 97.22%. Feed efficiency, protein retention, lipid retention, and Se retention indicated that a dosage of 4 mg Se/kg selenomethionine supplementation was the best dosage.Keywords: selenium, viability, growth, Cromileptes altivelis, humpback grouper

Tilapia (Oreochromis niloticus) is populer as resistant fish to environmental changes. Cultivating fish with a high stocking density can cause a decrease in water quality. It has an impact on susceptibility to disease due to decreased water quality. Immunostimulants from Phyto-pharmacy are needed to improve the non-specific immune system of fish from natural ingredients. Bay leaves (Syzigium polyanthum) have the potential to be used as an immunostimulant in fish. This study aimed to evaluate the extract of Salam leaves fortified in feed against the blood profile of Tilapia. The research was carried out in April - May 2018 using a completely randomized design (CRD) with 4 treatments and 3 replications. Salam leaf extract through feed affects the increase of leucocytes and blood erythrocytes of tilapia but does not affect hemoglobin levels and hematocrit levels. Doses of 2x10-2 g mL-1 increased fish blood leukocytes on day 21st to be the best treatment in this study.
