This study aims to determine the effect of partial replacement of traditional feed ingredients like corn and rice bran with brown seaweed Sargassum crassifolium on broiler performance. The study employed a fully randomized design, incorporating four replacement treatments (0%, 6%, 12%, and 18%) of brown seaweed Sargassum crassifolium within the broiler diet. Each treatment was replicated five times. A total of 100-day-old chicks were used in the experiment and reared under standard conditions. The results showed that inclusion of brown seaweed Sargassum crassifolium up to 18% in broiler diet did not affect (p>0.05) daily feed intake, daily weight gain, feed conversion ratio, live weight, carcass percentage with skin and without skin; however, it significantly (p<0.05) reduced the abdominal fat pad percentage of broiler. In conclusion, the inclusion of brown seaweed Sargassum crassifolium in the broiler diet up to 18% reduces corn utilization by 24.49% and rice bran by 54.45% at the starter period and reduces corn up to 21% and rice bran by 50% at the grower period without interfering with their performance.

Thus, the utilization of these wasted tea leaves for poultry diet is still limited due to the high in crude fibre content. Therefore, it is necessary to find out a method for solving this problem. One of the methods is a fermentation by using Aspergillus ficuum. This fungi is known as a microbe which produces cellulase for reducing fibre content. The objectives to investigate the appropriate rice bran (RB) and wasted tea leaf (WTL) combinations and incubation times when fermented with Aspergillus ficuum, and to study the effects of this fermentation process on enzymes (cellulase and protease) activity, and alteration of dry matter, crude fibre and crude protein contents. This experiment was performed in a completely randomized design in a 4 x 2 factorial arrangement of treatments with 4 replicates. The first factor was RB and WTL combination as follows: 100:0% (A1), 90:10% (A2), 80:20% (A3), 70:30% (A4). The second factor was incubation times as follows: 7 days (B1) and 9 days (B2). These combinations of RB and WTL were fermented by using Aspergillus ficuum at the dose of 6.3 x 10 12 CFU/mL. Measured variables were cellulase and protease activities, and alteration percentage in dry matter (DM), crude fibre (CF) and crude protein (CP). There was an interaction between RB:WTL combination and incubation time in cellulase activity (P<0.01) and CF content (P<0.01). Increasing WTL up to 10% in RB: WTL combination significantly augmented (P<0.05) cellulase activity at 9 days incubation time. The reduction percentage in CF occurred at 90:10% RB and TLM combination and 9 days incubation time. The incubation time for 9 days decreased the protease activity (P<0.01) as well as the reduction percentage in DM (P<0.05). The 90:10% RB and WTL combination improved the increasing percentage in CP (P<0.01). In conclusion, the appropriate RB and WTL combination and incubation time for fermenting the combination ratio of RB:WTL by using Aspergillus ficuum was 90:10% at 9 days incubation time.

The ability to induce a fermentation substrate by microbes dependent on the availability of an inducer in the medium. The enzyme activity would increase when a suitable inducer was in the medium. In order to increase protease and cellulase activities of Rhizopus oligosporus in processing Cassava Leaf Meal (CLM), it was necessary to add CLM in medium producing an inoculum Rhizopus oligosporus. This study was conducted in a completely randomized design with 4 treatments and 5 replications. The treatments were ratios of RB to CLM as follows: 100:0% (A), 90:10% (B), 80:20% (C), and 70:30% (D). The observed variables were protease activity, cellulase activity, dry matter content, organic matter content and the total colony of Rhizopus oligosporus numerically. The different ratios of RB to CLM significantly affected protease and cellulase activities as well as the content of dry matter and organic matter. The addition of 10% CLM to the RB medium increased protease and cellulase activities and reduced dry matter and organic matter contents. However, when more than 10% CLM was added, it reduced the protease and cellulase activities and increased dry matter and organic matter content. The highest total colony of Rhizopus oligosporus was numerically in treatment B (90:10% of RB to CLM ratio). The appropriate ratio of RB to CLM mixture as the inoculum of Rhizopus oligosporus, based on their enzyme activities, dry matter, and organic matter contents, and the total colony was 90:10% (treatment B).

Br. contains active compounds (such as steroids, flavonoids, saponins, and tannins) which can have several health benefits, including lowering cholesterol LDL and triglyceride as well as increasing feed consumption, body weight, and carcass weight of broilers. Therefore, the current experiment was conducted to evaluate the effect of Miana plant flour (Plectranthus scutellarioides (L.) R. Br. in the diet on blood serum lipid profiles and physiological organs of broilers. The experiment was performed on 100 dayold broiler chickens from strain Arbor Acres CP-707. The experiment was designed in a completely randomized design with five different levels of Miana plant flour (0%, 5%, 7.5%, 10%, and 12.5%) in broiler's diets as treatment, and each treatment was repeated four times. The diet was arranged iso-protein (21%) and iso-energy (2900 kcal/kg). The serum lipid profile measurement included the analysis of total cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL). Physiological organ analysis entailed the percentage of liver weight, pancreas weight, gizzard weight, small intestine weight, and length of parts of the small intestine (duodenum, jejunum, and ileum) of broilers. The results showed that the inclusion of Miana plant flour in the broiler's diet could significantly affect total cholesterol, triglycerides, HDL, and LDL in the serum of broiler chickens, and it affected duodenum length significantly. Furthermore, the inclusion of Miana plant flour in the broiler's diet had an insignificant effect on the percentage of liver weight, pancreas weight, gizzard weight, small intestine weight, and length of each part of the small intestine (jejunum and ileum) on broilers. In conclusion, the inclusion of Miana plant flour as much as 12.5% in broiler's diets reduced total cholesterol, triglycerides, and LDL, and increased the HDL and duodenum length without adverse effects on the other physiological organs of broiler chickens.

The addition of 10% CLM to the RB medium increased protease and cellulase activities and reduced dry matter and organic matter contents. However, when more than 10% CLM was added, it reduced the protease and cellulase activities and increased dry matter and organic matter content. The highest total colony of Rhizopus oligosporus was numerically in treatment B (90:10% of RB to CLM ratio). The appropriate ratio of RB to CLM mixture as the inoculum of Rhizopus oligosporus, based on their enzyme activities, dry matter, and organic matter contents, and the total colony was 90:10% (treatment B).

Present research was carried out to evaluate lycopene and nitrogen retention and crude fiber (CF) digestibility of steaming tomatoes waste powder which was combined with oil. Tomatoes waste in this experiment were local fresh tomato rejected from tomato field around West Sumatera province, Indonesia. The experimental factors were included the type of oil (palm and coconut oils) and dosage of oils (0.25, 0.5, 0.75, 1, and 1.25 %), and each treatment was replicated three times. The results indicated there was an interaction between the type of oil and dosage of oil on lycopene retention, and CF digestibility, while the type of oil and dosage of oil affected lycopene retention significantly. The dosage of oil also influenced lycopene retention, nitrogen retention, CF digestibility significantly. The addition of coconut oil in steaming tomato waste powder increased lycopene and nitrogen retention, and CF digestibility higher than the addition of palm oil to steaming tomato waste powder in broiler chickens. The lycopene and nitrogen retention, and CF digestibility of steaming tomato waste powder added 0.5% coconut oil was the best level for lycopene and nitrogen retention, and CF digestibility in broiler chickens.

This study used 100 DOC (day old chicken) broilers of Arbor Acres CP 707 strains. This study used a completely randomized design (CRD) with five treatments; each treatment was repeated four times. The treatments were presented as brown seaweed (Turbinaria murayana), by a rate of 0, 2.5%, 5%, 7.5%, and 10% in broiler ration. Data were analyzed using Analysis of Variance (ANOVA), and Duncan's Multiple Range Test to reveal the significant differences between different treatments applied. The results showed that the use of Turbinaria murayana up to the level of 10% in the ration can maintain performance, carcass quality, do not interfere with physiological organs, and can reduce the content of abdominal fat, liver fat and broiler liver cholesterol. The study concluded that the use of Turbinaria murayana as a rations supplemental material up to the 10% level can stimulate broilers' performance and carcass characteristics.

Br. contains active compounds (such as steroids, flavonoids, saponins, and tannins) which can have several health benefits, including lowering cholesterol LDL and triglyceride as well as increasing feed consumption, body weight, and carcass weight of broilers. Therefore, the current experiment was conducted to evaluate the effect of Miana plant flour (Plectranthus scutellarioides (L.) R. Br. in the diet on blood serum lipid profiles and physiological organs of broilers. The experiment was performed on 100 dayold broiler chickens from strain Arbor Acres CP-707. The experiment was designed in a completely randomized design with five different levels of Miana plant flour (0%, 5%, 7.5%, 10%, and 12.5%) in broiler's diets as treatment, and each treatment was repeated four times. The diet was arranged iso-protein (21%) and iso-energy (2900 kcal/kg). The serum lipid profile measurement included the analysis of total cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL). Physiological organ analysis entailed the percentage of liver weight, pancreas weight, gizzard weight, small intestine weight, and length of parts of the small intestine (duodenum, jejunum, and ileum) of broilers. The results showed that the inclusion of Miana plant flour in the broiler's diet could significantly affect total cholesterol, triglycerides, HDL, and LDL in the serum of broiler chickens, and it affected duodenum length significantly. Furthermore, the inclusion of Miana plant flour in the broiler's diet had an insignificant effect on the percentage of liver weight, pancreas weight, gizzard weight, small intestine weight, and length of each part of the small intestine (jejunum and ileum) on broilers. In conclusion, the inclusion of Miana plant flour as much as 12.5% in broiler's diets reduced total cholesterol, triglycerides, and LDL, and increased the HDL and duodenum length without adverse effects on the other physiological organs of broiler chickens.
