  An experiment was conducted with 80 unsexed broilers of the Arbor Acress strain to determine the capability of a carrot and fruit juice wastes mixture (carrot, apple, mango, avocado, orange, melon and tree tomato) in the same proportion for replacing corn in broiler diet. This study involved a Completely Randomized Design (CRD) with 5 treatments (0, 5, 10, 15 and 20% of juice wastes mixture in diets) and 4 replicates per treatment. Diets were isonitrogenous (22% crude protein) and isocaloric (3000 kcal/kg diet). Measured variables were feed consumption, average daily gain, feed conversion, as well as percentages of abdominal fat pad, carcass, digestive organs (liver, pancreas and gizzard) and heart. Data were analyzed by analysis of variance for CRD. Increasing juice wastes mixture levels in diets increased feed consumption (p<0.05) and average daily gain (p<0.01), while improving feed utilization efficiency (p<0.05). These treatments also affected (p<0.05) abdominal fat pad percentage but had no effect (p>0.05) on carcass, liver, pancreas, gizzard or heart percentages. In conclusion, up to 20% of juice wastes mixture could be included for the broiler diet to effectively replace up to 40% corn in the diet.

  The Juice Wastes Mixture (JWM) is a combination of waste from carrot and some fruits (apple, mango, avocado, orange, melon and tree tomato) in the same proportion after their juices were squeezed for fresh drink. The JWM could be as an alternative potential feed for replacing corn in the broiler diet. The problem of JWM as broiler feed is the high in crude fiber and low in metabolic energy contents. After processing the JWM by soaking in 20% concentration of rice hull ash filtrate for 72 hr (IJWM), its crude fiber decreased, while its metabolizable energy increased. An experiment was conducted to evaluate the utilization of IJWM in broiler diets. The experiment was performed in a completely randomized design with different levels of IJWM (0, 20, 25, 30, 35 and 40%) for replacing corn in the broiler diets. The variables measured were feed consumption, average daily gain, feed conversion, live body weight, abdominal fat pad percentage, carcass percentage, liver percentage and pancreas percentage. Every treatment was repeated 4 times. The results showed that the IJWM influenced the feed consumption, average daily gain, live body weight, feed conversion and abdominal fat pad very significantly (P<0.01). Meanwhile, liver percentage and pancreas percentage were not affected by the IJWM. In conclusion, the IJWM could be included up to 40% to effectively replace 80% corn in the broiler diets.

  This research was conduct to study the effect of high intensity movement raining on the amino acids metabolism and distribution in internal organ and ntestinal morphosis. About 40 Sprague-Dawley male rats were randomly divided intoexercised group and sedentary group. On day 10 after the initiation treatment average daily feed intake became significant lower and the average weight became significantlower on day 12 compared with the sedentary group. There was not significant difference about amino acids in the serum but valine which was significant lower than sedentary groups. Movement training increased significantly all amino acids content except cysteine in the intestinal tissue but failed in the liver and muscle eventhough all amino acids were higher in the muscle than sedentary group but cysteine. Amino acids digestibility was lower in exercised group and it became significant lower when it comes to lysine and histidine. Additionally, movement training decreased the numbers of lymphocyte but had no effect on the goblet cell villi height and crypt depth in middle jejunum.

  The problem of juice waste mixture as poultry diet was high in crude fiber and low in metabolizable energy contents. Experiments were performed to improve the nutrient quality of juice waste mixture by using steam pressure. The first experiment was designed in a completely randomized design with 4 different incubation times of juice waste mixture (0, 15, 30, and 45 minutes) in Autoclave (15 psi pressure and 121°C), and each treatment was replicated 5 times. Measured variables were crude fiber, crude protein, crude fat. The second experiment was to compare of crude fiber, crude protein, ether extract, NDF, ADF, cellulose, hemi-cellulose, lignin, nitrogen retention, amino acid profile, and metabolizable energy of juice waste mixture between treated vs. untreated one. The results showed that the crude fiber, crude protein, and crude fat of juice waste mixture were significantly affected (P<0.05) by incubation time in autoclave. The incubation time for 30 minutes decreased crude fiber and crude fat, but increased crude protein contents of the juice waste mixture. The crude fiber, ether extract, NDF, ADF, cellulose, and lignin contents between untreated vs treated reduced from 17.10, 6.24, 34.30, 24.40, 12.20, and 11.80% to 12.02, 4.06, 32.62, 22.05,10.50,11.55%, respectively. Meanwhile, nitrogen retention, crude protein, hemi-cellulose, and metabolizable energy increased from 59.99, 8.40, 9.90%, and 1744 kcal/kg to 65.51, 13.35, 10.57%, and 2550 kcal/kg, respectively. In conclusion, the incubation time for 30 minutes in autoclave was the best treatment for improving the nutrient quality of juice waste mixture.

  Two experiments were conducted to improve Juice Wastes Mixture’s (JWM’s) nutrient quality by using Trichoderma viride and to compare between treated vs. untreated one. This JWM consists of carrot, apple, mango, avocado, orange, melon and tree-tomato in the same proportion. Experiment 1 was performed in a 3 x 5 factorial experiment of completely randomized design with 3 replicates. First factor was Trichoderma viride concentration (5, 7 and 9%) and second factor was incubation period (0, 5, 7, 9 and 11 days). Measured variables were Crude Fiber (CF), Crude Protein (CP) and Ether Extract (EE). Experiment 2 was to compare nutrient content between treated vs. untreated one. Measured variables were JWM’s CF, CP, EE, NDF, ADF, cellulose, hemi-cellulose, lignin, nitrogen retention, amino acid profile and Metabolizable Energy (ME). There was a very significant (p<0.01) interaction between Trichoderma viride concentration and incubation period in which 7% Trichoderma viride and 5 day incubation period reduced CF and EE and increased CP content. CF, EE, NDF, ADF, cellulose, hemicelluloses and lignin contents between untreated vs. treated one declined from 17.10, 6.24, 34.30, 24.40, 12.20, 9.90 and 11.80% to 12.23, 3.72, 31.55, 22.43, 11.15, 9.12 and 11.28%, respectively. Meanwhile, nitrogen retention and CP increased from 58.40 and 8.40% to 63.64 and 11.29%, respectively. ME content of treated was better than untreated JWM (1774 vs. 2599 kkal/kg). Trichoderma viride treatment improved JWM’s amino acids profile. In conclusion, fermentation by 7% Trichoderma viride at 5 day incubation period was the best treatment for improving JWM’s nutrient quality.

  Two experiments had been conducted to improve the nutrient quality of carrot and fruits (apple, mango, avocado, orange, melon and tree-potato) juice waste mixture. Experiment 1: to determine effects of rice-hull ash filtrate level and soaking length on nutrient contents of this juice waste mixture. A 3 x 4 factorial experiment in a completely randomized design with 3 replicates was performed. First factor was rice-hull ash filtrate level (10, 20 and 30%) and second factor was soaking length (0, 24, 48 and 72 h). Measured variables were: crude fiber, crude protein and ether extract contents. Experiment 2: to compare treated vs. untreated juice wastes mixture numerically. Nutrient contents (crude fiber, crude protein and ether extract), anti-nutrition contents (phytate and tannin) and nutritive values (amino acids profile, nitrogen retention and metabolizable energy) of treated juice waste mixture were compared with untreated one. Results of experiment 1: crude fiber and ether extract reduced (p<0.01) by soaking in 20% rice-hull ash filtrate for 72 h, while crude protein increased (p<0.01). In experiment 2, crude fiber and ether extract decreased from 17.10 to 12.70% and 6.18 to 5.50%, respectively. Crude protein and phytate increased from 9.58 to 12.22% and 0.84 to 1.28%, respectively. Tannin content did not differ (1.60 vs. 1.59%). Amino acid contents were improved. Nitrogen retention and metabolizable energy were augmented from 59.99 to 67.57% and from 1744 to 2717 kcal/kg, respectively. In conclusion, carrot and fruit juice wastes mixture soaking in 20% rice-hull ash filtrate for 72 h improved its nutrient quality.
