The growth performance and blood profile of forty-eight (48), six (6) weeks old rabbit bucks of cross (Chinchilla and New Zealand White) were assessed for 10 weeks. The bucks were allotted on weight equalization basis in a 2 x 4 factorial experimental layout composed of 24 rabbits into steel hutches and wooden hutches each and on four (4) varying levels (0, 5, 10 and 15 mL/litre of water, respectively) of oyster mushroom (Pleurotus ostreatus Jacq ex fr.) extract. Six (6) bucks were assigned to each treatment group and replicated three times with two (2) bucks per replicate in a Completely Randomized Design. The phytochemicals of the oyster mushroom extract showed that 9,12-Octadecadienoic acid (Z, Z)- methyl ester was the most abundant. Results showed that the feed conversion ratio was significantly (P<0.05) best (6.08) in bucks reared in wooden cage and administered 15 mL oyster mushroom extract. Significantly (P<0.05) highest triglycerides (81.00 mg/dL) was obtained in bucks on steel hutch and on 5 mL oyster mushroom extract and lowest (55.00 mg/dL) in bucks on steel hutch and on 10 mL oyster mushroom extract. The lowest (P<0.05) lymphocytes (59.00%) were recorded in bucks on wooden cage and administered 10 mL oyster mushroom extract. It was concluded that oyster mushroom extract up to 15 mL/litre of water administered in either steel hutch or wooden hutch did not impair the growth performance and blood profile of rabbit bucks.

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.

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.

Abstract The objective of this work was to evaluate the effects of dietary supplementation with fructooligosaccharides (FOS) on the performance, hematology, and immunology of pacu (Piaractus mesopotamicus) juveniles. A total of 0 (control), 2.0, and 4.0 g kg-1 of the probiotic were added to the fish diets. Fish (49.3±4.3 g) were allotted into 12 tanks of 60 L, in a completely randomized design (n=4). After 60 days, final weight, weight gain, specific growth rate, and feed conversion ratio were improved in the fish fed with the prebiotic, although feed intake was not affected by the treatments. The number of red blood cells was higher only in fish fed with 2.0 g kg-1 FOS. The opposite was observed for the hematimetric indices mean corpuscular volume and mean corpuscular hemoglobin, which decreased in fish fed with 2.0 g kg-1 FOS. The number of defense cells, such as leukocytes and thrombocytes, also increased in the prebiotic treatments. The evaluated immunological parameters were not influenced by prebiotic supplementation. Dietary FOS supplementation improved pacu growth and health.

The problem that often arises in tilapia cultivation is the low growth of fish caused by the provision of feed that contains high energy but cannot be digested by fish. Utilization of commercial feed as feed for tilapia growth is less effective because the feed is still complex so it requires energy to be broken down into more simple. The method used in this study was a completely randomized design (CRD) which was then analyzed using one way ANOVA variance. The best results were obtained in treatment 4 with an absolute weight value of 2.97, absolute length of 1.19, specific growth rate of 2.75, survival of 83.33% and feed conversion of 0.95%. The conclusion of this study is the treatment of 4 absolute weight of 2.97 g and absolute length of 1.19 cm.

This research was conducted to determine the effect of giving different lime on the survival rate and growth of snack head seeds. This writing uses a completely randomized design (CRD) with 4 treatments and 3 replications. The hypothesis being tested was that the application of the limed lime had no significant effect on survival rate, the growth of snack head seed and the specific growth rate and lime administration differed significantly in feed conversion. The study was conducted at the Wet Aquaculture Laboratory, Palangka Raya University starting from February 3 - March 3, 2020. The results showed that the administration of different lime had no significant effect on survival rate, growth and specific growth rates but had a significant effect on feed conversion. The best survival rate of snack head seeds is in treatment D (250 g) that is equal to 57.73%, the best weight growth is in treatment C (200 G) that is equal to 3.16 grams, the best length growth is in treatment D (250 g) that is 2.57 cm, the best specific growth rate is in treatment D (250 g) which is 2.92% / day, and the best feed conversion value is in treatment D (250 g) which is 1.47%. Water quality such as temperature, acidity (pH) and dissolved oxygen (DO) are still in the normal range.
