The Patin catfish (Pangasius sp.) is a species of fish that is widely cultivated both in quarantine and in ponds. The success of Patin catfish cultivation is influenced by several factors, one of them is the feed. Patin catfish need essential amino acids to meet their needs. The addition of the amino acid (lysine) in the commercial feed not only affects the metabolism of the fish but also the content of Omega-3 and Omega-6 would be found in the fish. This study was conducted to observe the influences of essential lysine on the content of Omega-3 and Omega-6 of Patin catfish. This was an experimental study with a completely randomized design method, consisting of four treatments and five replications. The treatment which was given to experimental fish was commercial feed with the addition of lysine at different doses. The result indicated that the addition of lysine in commercial feed for 30 days of this research had a significant effect (p < 0.05) on the increase in the content of Omega-3 and Omega-6 in Patin catfish meat (Pangasius sp.). Based on the results of the current study, Patin catfish can be a good source of Omega-3 and omega 6 if the feed that is used in the cultivation process, contains lysine as an amino acid source.

The demand of fish meal as a protein source of feed increases with the increasing of fish culture activities, so this activities needed alternative protein sources to reduce the use of fish meal. The feed ingredient can be used as an alternative protein source is chicken intestine silage meal. The purpose of this research were to determine the percentage of chicken intestine silage meal to substitute fish meal in feed formulation of catfish fry based on the growth and feed efficiency. This research was conducted in June-July 2014 in the Laboratory of Aquaculture, Aquaculture Program, Faculty of Agriculture, Sriwijaya University. Research methods using Completely Randomized Design with six treatments and three replications (A : commercial feed, B: 0% chicken intestine silage meal and 100% fish meal, C: 25% chicken intestine silage meal and 75% fish meal, D: 50% chicken intestine silage meal and 50% fish meal, E: 75% chicken intestine silage meal and 25% fish meal, F: 100% chicken intestine silage meal and 0% fish meal). Results showed the utilization of chicken intestine silage meal significant effect on growth and feed efficiency, but not significant on survival catfish fry. Utilization of chicken intestine silae meal could substitute 100% fish meal in feed formulation of catfish fry.

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.

The aim of this study was to evaluate the physiological, zootechnical, and environmental benefits of the use of growth-promoting virginiamycin in the pirarucu diet. The research was conducted at the Carlos Eduardo Matiazze Fish Center, Federal University of Rondônia. In this study, 96 pirarucu fish were distributed in excavated nursery, divided into two treatment groups, control (0.0 mg kg−1) and treatment (75.0 mg kg−1) of feed with virginiamycin, with 8 replications in a completely randomized design. With virginiamycin being incorporated into commercial feed, for 107 days of cultivation, the fish were slaughtered with an average weight of 9.18 kg. Carcass weight, flesh, residues, and internal organs/guts were evaluated to calculate slaughter yields, Spearman’s correlation, and subsequently regression. For the quantification of micronuclei, a count of 1,000 cells per blade was determined. The means of the results obtained were contrasted by the Student’s t-test (α = 0.05). Virginiamycin did not cause oscillations in the limnological variables of the nursery but could reduce micronucleated erythrocytes. The average yields in carcass, flesh, and waste were 67.43, 53.4, and 43.14%, respectively. Virginiamycin provided strong correlations (ρ2) for better productive yields and lower slaughter residue. The hepatosomatic index indicated a strong relationship between liver weight and fat. Virginiamycin may be recommended for fish farming in pirarucu fattening because it contributes to the productive efficiency and sustainability of the fish farm system.
