Organic acids have recently been identified as promising replacements for antibiotics in aquafeeds that promote fish growth and feed efficiency. This study evaluated the inclusion of fumaric acid (FA; 0, 5, 10, 15, 20, and 30 g/kg) in diets (350 g/kg CP; 3.4 kcal digestible energy/g) of Nile tilapia juveniles. Fish (average weight 1.7 ± 0.1 g) were distributed in three 40 L aquaria per treatment (13 fish/aquaria) in a completely randomized design. Over 35 days, the fish received the experimental diets three times daily to apparent satiety. The maximum weight gain, feed efficiency ratio, and protein efficiency ratio were recorded in fish supplemented with 14–15 g/kg FA. After 28 days, Enterobacteriaceae was registered only in the gut of tilapia without FA augmentation. Gram-negative bacteria in the fish gut decreased (p < 0.05) in fish receiving 17 g/kg of dietary FA, increased after this level. The intestinal villi height and width were affected (p < 0.05) by FA levels and feeding time. Thus, inclusion of 15 g/kg of FA was effective in promoting growth, improving intestinal morphometry, and decreasing negative gut bacteria of Nile tilapia juveniles after 35 days.

In order to evaluate the performance of Nile tilapia (Oreochromis niloticus), daily feeding amounts were varied in an experiment following a completely randomized design for 154 days and consisting of four treatments with three replications each, totaling 12 tanks with 3 m3 (3 x 1 x 1 m) of area each at densities of 5 fish m-3 (initial) and 3 fish m-3 until the end of the experiment. Throughout the experimental period, the daily amount of feed was varied and delimited for each feeding time (8h00, 11h00, 14h00 and 17h00) as: 25; 25; 25 and 25% in daily treatment 1 - T1; 20; 30; 30 and 20% in treatment 2 - T2; 30; 20; 20 and 30% in daily treatment 3 - T3; and 20; 30; 20 and 30% in treatment 4 - T4. Feed was offered six days a week, with extruded isocaloric (1,412 KJ) and isoproteic (32% crude protein) diets from 2 to 4 mm. Every two weeks, a sample containing 30% of stocked individuals was collected in each replication to monitor fish growth. Nile tilapia (O. niloticus) fed in daily amounts of 20; 30; 20 and 30% showed a better growth performance in the final of experiment, mainly on biomass, final average weight and feed conversion.

Abstract: Fish growth descriptions constitute the parameters which are influenced by internal and external condition. The external factors include water quality, feed quality and feed quantity. Feed quality including the simpicia papaya particle size which contains protease enzyme and saponin as additional ingredients for grouper feed. Currently, grouper’s growth is relatively low, when in fact the protein content of its feed is high. This research aims at obtaining data on charachter particle of papaya simplicia powder and the grouper’s absolute weight and grouper’s protein efficiency ratio which is fed with simplicia papaya powder. The research is conducted using Completely Randomized Design with 5 treatments and 3 repetitions (A: 60 μm simplicia papaya 3.5% application, B: 100 nm simplicia papaya 3.5% application, C: 60 μm simplicia papaya 2% application, D: 100 nm simplicia papaya 2% application, and E: 0% without simplicia papaya). Simplicia papaya powder was made from dried papaya, then mashed using disc mill and filtered with sieves measuring 60 μm and 100nm and the grouper cultivation is done in a Floating Net Cage in Pangandaran Regency. The addition of papaya simplicia at A and B to the grouper’s feed has some highest average daily gain by 3.70 % and 3.73 %. The characteristics of simplisia papaya powder size 60 μm and 100 nm do not have a different effect on the growth performance of grouper seeds.

The need to seek for alternative feed materials with nutritional and medicinal values to support livestock growth necessitated this study. Forty-five unsexed rabbits crosses (Chinchilla × Newzealand white) 5- 6 weeks old with average weight of 720g were used in a 10- week feeding trial to evaluate the performance of growing rabbits fed on varying levels of dried okra leaves. The rabbits were assigned into five treatment groups containing dried okra leaves (DOL) at 0%, 2.5%, 5%, 7.5% and 10% inclusion levels for dietary treatments (T1, T2, T3, T4 and T5) respectively. Each treatment consisted of 9 rabbits and replicated thrice with each replicate consisting of 3 rabbits in a completely randomized design. Data collected were subjected to one-way analysis of variance (ANOVA). Results indicated that daily feed intake was significantly (P<0.05) largest in rabbits fed 5.00% inclusion level of dried okra leaves (84.57g) and least in rabbits fed 0.00% level of inclusion of dried okra leaves (72.12g). Feed efficiency (FE) was poorest (P<0.05) in rabbits fed 10.00% DOL (0.15%) and best (0.20%) in rabbits fed 2.50% dried okra leaves. It was concluded that okra leaves can be included in diets for growing rabbits and 2.50% level of dried okra leaves inclusion is recommended for adoption by farmers to maximize profit.

This study aims to get growth and feed efficiency of Nile tilapia (Oreochromis niloticus) with plant oils supplement from paring coconut (P.C.) and candlenut (C.N.) enrichment of Se in rations formula. The oil of P.C. was dominated by saturated fatty acid (SFA) lauric (42.67%), while the extract of C.N. was unsaturated fatty acids (UFA), linoleic (34.4%), and oleic (48.99%). The extract of P.C. and C.N. or mix oils added 4% in basal ration formula (28% crude protein (C.P.) with energy-protein ratio 8 kcal/kg). Completely Randomized Design (6 &times; 3) consists R1: basal ration; R2: basal formula with blend of paring coconut and candlenut oils (2% PC + 2% CN); R3: blend oils (R2) with trace additive Se; R4: 4% PC + Se; R5: 4% CN + Se; R6: control ration (32% CP). The result of production parameters showed that blend oils supplement enrichment Se 0.15 ppm in feed formula with ratio SFA: UFA = 1: 1 was the best growth rate equal with high protein feed. Feed efficiency ranged from 50.14-57.93% and protein efficiency ratio 1.72-2.06 both for CN oil (SFA: UFA = 1 : 2), paring coconut (SFA : UFA = 2 : 1) or blend oils (SFA : UFA = 1 : 1). Incorporation of blend oils with Se can be used for Nile tilapia fingerlings (&ge; 10 g). Paring coconut oil was trend increasing on feed efficiency for tilapia bigger stadium (&ge; 30 g).

The This study evaluated the effect of levels of garlic powder (0.0, 1.0, 2.0 and 3.0 g.kg-1) added to diets for Nile tilapia on animal performance, villi height and diet digestibility. The rations consisted of pellets and tilapia and were fed to apparent satiation for 60 days. 120 fish, with initial average weight of 4.20 ± 0.4 g, were masculinized and distributed in 24 aquariums of 70L in a randomized design consisting of four treatments and six replications in a closed circulation system with constant aeration. 240 fishes was used for feces collected by an indirect method (Guelph modified system) and estimation of coefficients of apparent digestibility using 0.5 g.kg-1 of chromic oxide as an inert indicator incorporated into the ration. No significant differences in performance related to organ weight, the hepato-somatic index, the viscero-somatic fat index and villi height were observed. However, the apparent digestibility coefficient of rations was negatively affected by the addition of garlic powder. Garlic powder as an additive in rations for Nile tilapia did not provide positive effects as a growth promoter and worsened the digestibility of nutrients among the tested treatments.

The effect of feeding graded levels of toasted banban ground out meal on rabbit weaners was investigated. A total of fifty white rabbit weaners of 6 - 8 weeks with an average weight of 366,7 gwere fed the graded level of tested bambara nut meal at 0. 5, 15, 25 or 35% inclusion level in a complete randomized design experiment for a period of six week. The final live weight, daily feed intake were not influcticed (P>0.05) by the level of bambara nut meal in the diet. However, positive influence of the graded level of bambara nut meal was observed on the rabbit daily weight gain, feed efficiency dressed carcass, dressing percentage and ment: bone ratjo. Rabbits on the 25 and 15% bambara nut inclusion levels were found to have similar (P>0.05) daily weight gain and dressing percentage with the control ration. Rabbit on the 5% bambara nut level diet had the least feed efficiency (0.22) and meat: bone ratio (3.6), while the dressed weights of rabbit fed the diet containing 25% bambara nut meal had the highest dressed carcass weight (501.6g). Rabbits' carcass cut-up parts as well as internal organs (liver, heart, kidneys and lungs) were not influenced by the dietary levels of bambara nut meal. But the pelt weight, empty gut weight, lipid and moisture contents were significantly (P<0.05) influenced by the levels of bambara nut meal in the diet.
