Abstract

The use of agricultural waste in poultry diets presents a sustainable solution to reduce feed costs and environmental waste. This study investigates the nutritional enhancement of banana peel flour (TKPF) and cassava peel flour (TKSF) through fermentation. The fermentation process significantly improved the crude protein content and metabolic energy of both by-products, with TKPF showing an increase in protein from 7.08% to 11.25% and metabolic energy from 2010 Kcal/kg to 3072.50 Kcal/kg. Similarly, TKSF exhibited a 30.56% increase in crude protein (from 11.84% to 15.46%) and a 68.5% increase in metabolic energy (from 1310 Kcal/kg to 2210 Kcal/kg). Both fermented products also demonstrated a reduction in crude fiber and anti-nutritional factors, making them more digestible and safer for poultry. The findings suggest that fermented banana and cassava peels can be used as cost-effective and environmentally friendly alternatives to traditional feed ingredients in poultry diets.

Abstract

This study aimed to evaluate the interaction between Palm Fatty Acid Distillate (PFAD) and high-tannin mangrove fruit extract (Sonneratia alba) on the in vitro digestibility of dairy cattle feed fiber fractions. The experimental design used a completely randomized factorial 3×4 pattern with three replicates. The first factor was the PFAD level (0%, 3%, 6%) and the second factor was the mangrove fruit extract dose (0%, 0.5%, 1%, 2%). Fermentation was carried out using the Tilley and Terry (1963) rumen stage method using fresh goat rumen fluid. The parameters observed included the digestibility of neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose, and cellulose. The results showed that PFAD, mangrove fruit extract, and their interaction had a significant effect (P<0.05) on the digestibility of NDF and cellulose, but did not have a significant effect on ADF and hemicellulose. The combination of 3% PFAD and 0.5–1% extract provided the highest digestibility. Increasing PFAD and tannin reduced digestibility due to the fat coating effect and the formation of tannin complexes with structural carbohydrates. The combination of PFAD and mangrove tannin can be optimized as a functional feed additive based on local resources that improves rumen fermentation efficiency without reducing fiber digestibility.

Abstract

HIGHLIGHTS- Bacillus sp. probiotics can replace 100% inorganic phosphate fertilizer.- Sorghum stem diameter strongly correlates with juice volume.- Juice yield was not affected by phosphorus dose or Bacillus sp. colony size.- Sorghum juice sugar content reached 11.77–12.75% Brix.- Phosphate-solubilizing bacteria improved phosphorus availability in ultisol. ABSTRACTThis study was conducted to observe the effects of phosphate-solubilizing bacteria (PSB) combined with different phosphorus fertilizer levels on the juice characteristics of the BMR sorghum mutant line. The research was carried out at the Edufarm of the Faculty of Animal Science, Andalas University, Padang, using a randomized block design (RBD) with four treatments and four replications. The treatments were as follows: P0 = Urea + KCl + 0% TSP + PSB; P1 = Urea + KCl + 50% TSP + PSB; P2 = Urea + KCl + 75% TSP + PSB; and P3 = Urea + KCl + 100% TSP (control). The PSB used was obtained from Waretha Probiotics, consisting of Bacillus sp. culture at a dose of 10 mL per planting hole, equivalent to 10⁷ cfu/g. The parameters measured were sugar content (%Brix), volume of stem juice (mL), and the correlation of various parameters with stem juice volume. The results showed that the application of probiotic Bacillus sp. and different dosages of phosphorus fertilizer did not result in significant differences for all parameters (P > 0.05). Sugar content and juice volume ranged from 11.78 to 12.75 (%Brix) and 188.75 to 218.5 (mL/stem), respectively. The correlation coefficient analysis indicated significant positive correlations between stem diameter (r = 0.575*) and fresh stem weight (r = 0.504*) with the volume of sorghum stem juice. It was concluded that the application of PSB from Bacillus sp. can replace phosphorus fertilizer, producing sugar content and juice yield comparable to the 100% P fertilizer treatment. A correlation was observed between stem diameter and fresh stem weight with stem juice volume. PSB was found to play a crucial role in increasing phosphate availability to plants. The implications of this research include the potential production of forage sorghum with high Brix content for ruminant energy and Water-Soluble Carbohydrates (WSC) for silage production.

Abstract

Brown Midrib (BMR) sorghum is a mutation-derived variety with low lignin and high non-structural carbohydrate content, potential as a ruminant forage. The ratoon system allows for repeated harvesting without replanting, thus providing an efficient forage supply. This study aimed to evaluate the agronomic characteristics and biomass productivity of BMR mutant sorghum in primary plants, the first and second ratoon. The study was conducted experimentally using a randomized block design with three treatments (primary, first ratoon, and second ratoon plants) and four replications. The parameters observed included agronomic components (plant height, number of tillers, stem diameter, and leaf size), stem sugar value (Brix), proportion of plant structures (stems, leaves, and panicles), panicle production, forage production, and livestock carrying capacity. The results showed that plant height was not significantly different (P>0.05) between primary and ratoon plants, while stem diameter and leaf size decreased gradually from the first to the second ratoon. The Brix value showed a highly significant difference (P<0.01), with the highest value in the first ratoon and the lowest in the second ratoon. The proportion of stems and leaves decreased in the second ratoon, whereas the proportion of panicles and panicle production increased significantly (P<0.01). The highest forage production was obtained in the second ratoon at 52.08 tons/ha, while the total production of the three harvests reached 112.28 tons/ha with a carrying capacity of 8.8 AU/ha. From the results of this study, it can be concluded that the ratoon system does not reduce the biomass productivity of BMR mutant sorghum and can maintain agronomic quality until the second ratoon. With its high production potential and good regrowth ability, BMR mutant sorghum is worthy of development as a sustainable forage source in ruminant livestock farming systems.
