The objective of this work was to evaluate fish oil replacement by soybean oil in diets, as for the effects on the performance and body composition of juveniles of fat snook (Centropomus parallelus). The experiment was carried out in a randomized block design, with three treatments (lipid sources) and six replicates, in a 60-day period. Fat snook juveniles (24.17±0.28g) were distributed in 18 experimental tanks of 200 L each, equipped with aeration and heating systems, under continuous water renovation (800% per day). Three isoproteic (44% CP) and isoenergetic (4,635 kcal CE kg-1) diets were formulated to comprise three replacement rates (0, 50, and 100%) of fish oil by soybean oil. Biometric analyses were done to evaluate fish performance, and two entire specimens from each replicate were used for body composition analyses. The zootechnical indices of weight gain (38.68±5.41 g), feed conversion (1.38±0.10), and specific growth at 1.70±0.18% weight gain per day were considered satisfactory. Lipid source substitution does not affect the performance and body composition of fat snook juveniles, which suggests that soybean oil can replace fish oil in diet formulation.

This study aims to determine the performance of  ducks on the effect of differences in cage temperature. This study used 54 5-week-old male ducks selected from 66 ducks. The research method used was randomized block design (RBD). The treatment used is the regulation of the temperature of the cage which is divided into three temperature levels, namely: A (cold temperature), B (room temperature), and C (hot temperature). The observed variables were duck performance in the form of feed consumption, body weight gain and feed conversion. The results of this study indicate that the difference in temperature of the cage became a very significant (P<0.01) on the consumption of rations, weight gain and conversion. The results of the study concluded that the maintenance of ducks at three different cage temperatures had a very significant (P<0.01) on feed consumption and body weight gain, but had no effect on feed conversion. The best results were found in the temperature of the cold cage with the consumption of rations of 2964.33 g/head, which resulted in body weight of 711.83 g/head of g/head, and conversion of 4.2. While the body weight of 1437 percentage of carcass was 67.64% in the study. The highest yield IOFC results (income over feed cost) cage in cold temperatures with a profit of Rp. 3,375.15/head. The maintenance of  ducks at three different cage temperatures had no significant effect (P>0.05) on the weight of the spleen, thyroid and kidney and the work of the spleen, thyroid and kidney organs was still normal

It was used 72 pigs, 36 castrated males and 36 females, with initial weight of 14.97 ± 0.36 kg to evaluate levels of dietary available phosphorus (aP). The animals were distributed in a completely randomized block design, with six levels of aP (0.107; 0.214; 0.321; 0.428; 0.535 and 0.642%), six replicates and two animals (one castrated male and one female) per experimental unit. Air temperature and relative humidity in the room were kept at 24.5 ± 1.2°C and 76.3 ± 8.5%, respectively. The levels of aP influenced both daily feed intake and daily weight gain, which increased in a quadratic way up to the estimated levels of 0.420% and 0.443%, respectively and feed conversion, which improved in a quadratic manner up to the estimated level of 0.461%. It was observed the effects of levels of aP on quantity of phosphorus and ash in the bone, which increased in a quadratic manner up to the estimated levels of 0.525% and 0.520%, respectively. Levels of Ap affected daily protein deposition in the carcass, which increased in a quadratic way up to the estimated level of 0.394%. There was no effect of levels of aP on daily fat carcass deposition. Levels of aP that provided the best results for daily weight gain, feed conversion and bone mineralization in swines with high genetic potential for lean meat kept in thermoneutral environment, from 15 to 30 kg are 0.443, 0.461 and 0.525%, respectively, corresponding to estimated daily intakes of 5.25, 5.45 and 6.14 g of aP.

With the objective of evaluating levels of lactose in diets for piglets weaned at 21 days of age, it was carried out an experiment with 72 animals, with average weight of 6.12 kg, distributed in a completely randomized block design with four diets (0, 4, 8, and 12% lactose), six replicates, and 3 animals per experimental unit. Animals were fed the experimental diets from 21 to 35 days of age and they were fed a lactose-free basal diet from 36 to 49 days of age. The lactose levels did not affect daily weight gain, feed intake and feed conversion of piglets from 21 to 35 days of age. The use of lactose levels in the diets also did not affect performance of the piglets assessed from 21 to 49 days old. Diets also did not influence villous height, crypt depth and villous:crypt ratio. Lactose resulted in greater diversity and balance of the intestinal microbial community. The Lactobalillus spp. richness increases with the addition of lactose in diet up to the level of 8% in relation to the total number of intestinal microorganisms, which may a possible improvement of intestinal health.

This study was conducted to analysis the effect of levels of white kabesak (Acacia leucophloea Roxb.) Willd. leaves in the diet on feed intake, digestibility and body weight gain of Kacang goats. The completely randomized block design using 5 treatments and 5 replications was used in this experiment. The treatments were 5 concentrate feeds containing different levels of white kabesak leaves i.e. 0, 10, 20, 30 and 40% in the dry matter (DM) basis (representing T0, T1, T2, T3 and T4 treatments, respectively). The feeds were set up to contain 11.5-12.5% of crude protein (CP). Concentrate feed and native grass was fed at ratio of 60 : 40 was fed to 5 local male goats (age 1-1.5 years old and initial weight of 16.7±5.0 kg). The results showed that DM, organic matter (OM), and CP intake of T0 was not significantly different from those of T1 goats, but it was significantly higher (P<0.05) than those of T2, T3 and T4. The DM, OM, CP, and crude fiber (CF) digestibility as well as body weight gain in T2 goats were significantly higher (P<0.05) and had feed conversion ratio that was significantly better (P<0.05) compared to those of the other feed treatments. In conclusion, the most optimum level of white kabesak (Acacia leucophloea Roxb.) Willd. leaves used in concentrate feed for goat was 20 %.

The objective of this study was to evaluate different textures and storage forms of corn in piglet diets. Two experiments were conducted, one of which tested digestibility of nutrients and the other diet performance. In the digestibility trial, 24 crossbred (Landrace X Large White) barrows with an initial weight of 18.7 ± 1.5 kg were used. They were kept in metabolic cages in a randomized block design using the factorial arrangement 2 X 2 (type of corn - dent and flint X type of storage - moist grain silage and dry grain) and six replicates, with one animal as the experimental unit. The values of metabolizable energy (ME) obtained were 3841 kcal of ME/kg of dry matter (DM) from dry corn, 3912 kcal of ME/kg of DM from moist corn, 4022 kcal of DM from ensiled dry corn and 3928 kcal of ME/kg of DM from ensiled humidity corn. The ensilage process increases the digestibility coefficient of dry matter and crude protein and increases the digestible energy of the diets, independent of the process form. The type of corn did not influence these variables. In the performance trial, 60 barrows (initial weight of 6.5 ± 1.5 kg) of the same stock were used during 28 days of post-weaning distributed in the same experimental design, with five replicates and three animals as the experimental unit. The treatments did not influence the daily weigh gain or the daily feed intake. The dentate corn and the ensilage process decreased the feed conversion of the independent form (no significant interaction). The substitution of dry for ensilage corn increased the digestibility of the nutrients in the diets and the feed conversion of the piglets from 7 to 15 kg. Dentate corn promotes best feed conversion in this phase.
