Effect of molasses addition to complete calf starter (CCS) and the following pellet processing was evaluated with 12 Holstein-Friesian (HF) calves (7-14 d old with $42\;{\pm}\;5.5\;kg$ average BW), with 6 calves (replicate) per treatment. The CCS was formulated with 65% concentrate calf starter and 35% local corn fodder. On the CCS, molasses was added either 5% (M5) or 10% (M10), then the mixture was pelleted and fed to the calves for 7 weeks. Molasses addition, regardless of addition level, improved (p<0.05) both the durability and hardness of the pellet which contains 35% of high fibrous local corn fodder. Upon feeding to calves, the feed intake and daily gain were numerically higher with 5% molasses addition compared to 10% molasses addition. Blood VFA level was remarkably higher (p<0.01) in calves fed M10 than calves fed M5. There was no difference (p>0.05) in blood glucose level between M5 and M10. Length and number of papillae were not different (p>0.05) by the addition levels of molasses. However, there was one exception in number of papillae at caudo-dorsal sac which were higher (p<0.05) number in M5 than M10 calves. Considering the quality of CCS pellet, calf performance and rumen development, there was no additional benefit of 10% molasses addition compared to 5%. From the results of this study, 5% molasses addition could be recommended for local farmer when they utilize local corn fodder to make CCS for HF calves in Indonesia.

To standardize proper formulation of urea and molasses, the former to increase crude protein content of tropical grass and the latter for improving its silage quality, we examined the fermentation quality of silage of fresh and wilted napiergrass (Pennisetum purpureum Schumach) with different levels of urea and molasses with or without lactic acid bacteria (LAB). Silage was made of napiergrass with conditions of fresh young (Exp. 1),young wilted for half day (Exp. 2) and fresh mature (Exp. 3). Chopped plant materials of about 1cm length were ensiled into a laboratory silo and incubated for one month at $25^{\circ}C$. The treatments were the combination of 0, 0.2 and 0.6% of urea and 0, 2 and 5% of molasses (fresh material basis) with or without LAB inoculation. After opening the silo, pH, organic acids, volatile basic nitrogen (VBN) and total nitrogen (TN) were determined. Addition of molasses significantly (p<0.01) lowered pH values in three experiments. Though molasses addition increased lactic acid production even at a higher level of urea, pH values at 0 and 2% molasses were significantly increased by urea in fresh and wilted young silages, but in fresh mature silage it occurred only when molasses was not added. VBN/TN at 0.6% urea were decreased significantly by the highest molasses in three experiments. Significant increases in TN by the increasing of urea addition were observed at all levels of molasses in wilted young and fresh mature silages. In conclusion, a combination of 5% molasses and 0.6% urea could improve the nutritive and fermentation qualities of napiergrass silage under young, wilting and mature conditions.

Influences of forage DM and addition of cane molasses on silage characteristics of berseem (Trifolium alexandrium) and lucerne (Medicago sativa) and their ruminal digestion kinetics in Nili buffaloes were studied. Berseem and lucerne fodders (at one tenth bloom) were ensiled with wheat straw in laboratory silos to achieve 20, 30, 40% forage DM and without wheat straw (control); each forage DM level was supplemented with 2, 4 and 6% of cane molasses at ensiling. The pH and lactic acid contents of berseem and lucerne silages were affected by both forage DM and addition of molasses. Dry matter, CP and true protein (TP) of berseem and lucerne silages were affected by forage DM at ensiling but were not affected by the addition of cane molasses. Higher DM, CP and TP losses were observed when berseem and lucerne fodders were ensiled either without wheat straw or with wheat straw to achieve 20% and 40% forage DM at ensiling compared with 30% DM at ensiling. Fiber fractions (NDF, ADF, hemicellulose and cellulose) of berseem silage and lucerne silage were significantly increased with increasing forage DM at ensiling. Addition of cane molasses did not affect the DM, CP, TP and fiber fractions of both berseem and lucerne silages. Berseem and lucerne ensiled at 30% DM with 2% cane molasses were screened for comparative ruminal digestion kinetics with their respective fodders. Addition of wheat straw to berseem or lucerne fodder at ensiling depressed DM and NDF ruminal degradability. However, ruminal lag time, rate of degradation and extent of digestion of silages were similar to their respective fodders. In conclusion, berseem and lucerne could be ensiled with wheat straw to increase their DM to 30% along with 2% molasses for buffaloes.

Biofilms are of vital significance in bioconversion and biotechnological processes. In this work, sugarcane molasses was used to enhance biofilms for the improvement of the production of fumigaclavine C (FC), a conidiation-associated ergot alkaloid with strong anti-inflammatory activities. Biofilm formation was more greatly induced by the addition of molasses than the addition of other reported biofilm inducers. With the optimal molasses concentration (400 g/l), the biofilm biomass was 6-fold higher than that with sucrose, and FC and conidia production was increased by 5.8- and 3.1-fold, respectively. Moreover, the global secondary metabolism regulatory gene laeA, FC biosynthetic gene fgaOx3, and asexual central regulatory genes brlA and wetA were upregulated in molasses-based biofilms, suggesting the upregulation of both asexual development and FC biosynthesis. This study provides novel insight into the stimulatory effects of molasses on biofilm formation and supports the widespread application of molasses as an inexpensive raw material and effective inducer for biofilm production.

The effect of molasses addition and hot temperature on the ensiling characteristics of napier grass (Pennisetum purpureum Schum.) were studied. Napier grass was harvested five times at intervals from 22 to 39 days and each harvest was divided into two equal portions. The half portion was ensiled directly and the other half was ensiled after mixing with molasses into polyethylene bag silos of 15 kg capacity. Molasses was added at the rate of 4% of fresh weight of the grass. One half of the each treatment was conserved at a room of $40^{\circ}C$ for a month and then moved to an ambient temperature room. The other half was kept at ambient temperature for the whole experimental duration. The silages were opened 3 to 7 months after ensiling. Addition of molasses enhanced lactic acid fermentation by increasing lactic acid content and reducing pH value, ammonia nitrogen and acetic, propionic and butyric acid contents of the silages in both temperature treatments. Enhanced temperature increased pH value and decreased acetic, propionic and butyric acids.

Hydrolysis of plant protein to non-protein nitrogen (N) or ammonia can reduce quality of silage crops. Heating or non-enzymatic browning is a treatment to inhibit this hydrolysis. This experiment was conducted to examine the effects of pre-heated soybean meal and molasses on the fermentation quality of napiergrass silage. The initial growth of napiergrass was harvested at 85 days of age and immediately chopped into about 1 cm length. About 700 g of the grass was ensiled into a laboratory silo (1.0 liter polyethylene container) and incubated for 30 days at room temperature ($28^{\circ}C$). No additives (control), molasses, soybean meal and molasses + soybean meal treatments were prepared. All additives were non-heated or heated in an oven at $150^{\circ}C$ for 30 minutes before ensiling. Molasses was added at 3% on the fresh weight basis and soybean meal was added at 0.5% N, respectively. After opening the silo, pH, total nitrogen (TN), volatile basic nitrogen (VBN), lactic acid (LA), acetic acid (AA), butyric acid (BA) and dry matter (DM) contents were determined. The data were analyzed statistically by analysis of variance. Compared with control, molasses addition significantly decreased pH value, VBN/TN, AA and BA and increased LA production. Soybean meal addition significantly increased TN and VBN/TN of silage. Both molasses and soybean meal addition significantly reduced pH value, AA, and BA and increased DM and LA contents of silage. The heating of additives was only effective to reduce VBN/TN production compared with non-heated additives in soybean meal and soybean meal with molasses addition.

Two experiments were conducted to investigate effects of molasses addition to silage materials in ensiling Socheongryongtang meal on the nutritive quality of silage, palatability and various ruminal parameters in Korean native goats. In Experiment 1, Socheongryongtang meal silage was produced by the addition of 0, 0.5, or 1.0% molasses and stored for 40 days at room temperature. There were three replicates per treatment. Lactic acid contents of Socheongryongtang meal silage containing molasses(0.5 and 1.0%) were significantly(p<0.05) higher than that of the control(0%). However, the pH and butyric acid contents of Socheongryongtang meal silage containing molasses(0.5 and 1.0%) were lower than those of the control(0%). In addition, molasses(0.5 and 1.0%) increased the number of lactobacillus, but decreased the number of fungi in Socheongryongtang meal silage. In vitro dry matter disappearance tended to increase by molasses addition. In Experiment 2, three 1.5-yr-old Korean native female goats were employed in cross-over design to measure the palatability and various ruminal parameters of Socheongryongtang meal silage. Feed intake of Socheongryongtang meal silage containing molasses(0.5 and 1.0%) for 30 min significantly higher than that of control(0%). Silmilar trend was found when the feed intake was measured for 6 hr. In various ruminal parameters, molasses addition to silage materials increased propionic acid(P) and total volatile fatty acid contents, but decreased pH, acetic acid (A), and butyric acid. The A/P ratio was the lowest in 1.0% molasses treatment group. It is concluded that molasses addition in ensiling Socheongryongtang meal could enhance its nutritional quality and lengthen storage period. Also the palatability of silage was improved by the addition of molasses.

The study aimed to evaluate the influence of molasses in ensiling cassava and Gliricidia tops, common crop residues in the farming systems of Vietnam. Four levels of sugarcane molasses: 0, 30, 60 and 90 kg per tonne of fresh material, and two storage periods (2 and 4 months) for each of the two plant species: Cassava (Manihot esculenta, Crantz) and Gliricidia (Gliricidia sepium, Jacq.) were allocated in a 4${\times}$2 factorial completely randomized block design with 3 replicates. A total of 48 plastic bags, each one containing 10 kg herbage were used. Based on the colour, smell and mold appearance, all the silages were considered to be acceptable but with more spoiled silages with higher levels of additives. DM of herbages (25.8% and 22.4% in cassava and Gliricidia tops, respectively) were not changed during ensiling and the molasses additive had no significant effect on the silage DM. Contents of CP and NDF in the cassava tops silage decreased significantly with increased level of molasses and storage period, respectively. The mean pH values of non-molasses silages were 4.39 in cassava tops and 4.60 in Gliricidia tops. Increased additive levels significantly reduced silage pH in Gliricidia (p<0.01) but not in cassava tops silage (p=0.10). Longer storage period significantly reduced pH in both silages. The water soluble carbohydrate (WSC) concentrations of cassava tops and Gliricidia tops were reduced by 90 and 80%, respectively, after ensiling. Molasses addition increased significantly the silage WSC concentrations. HCN contents in the fresh cassava and Gliricidia tops were reduced by 68 and 43%, respectively, after 2 months ensiling, and were continuously reduced during storage. A reduction of 25% and 42% in the tannin content of fresh cassava and Gliricidia tops, respectively was found after ensiling. Storage time and molasses additive had little affect on the tannin content. Silage lactic acid concentrations were around 1,0% of DM in cassava and 1.7% of DM in Gliricidia top silages, and no effect of molasses additive and storage time was found. It is concluded that cassava and Gliricidia tops residues can be preserved successfully by ensiling, and only low levels of molasses additive are needed to improve silage fermentation.

This study was conducted in order to determine a proper level of molasses addition through the analysis of changes in appearance, nutritive and silage parameters before and after ensiling or deepstacking of broiler litter, to evaluate the effect of pelleting processed broiler litter and to develop methods to enhance palatability of broiler litter and reduce the adjustment period by ‘Hanwoo’ steers. Molasses addition was effective in ensiling and deepstacking of broiler litter and the proper addition level was about 5%. Changes in nutritive values of broiler litter by ensiling and deepstacking with or without molasses treatment were not great. Adding 5% molasses at deepstacking of broiler litter did not affect(P<0.05) in vitro digestion of dry matter and organic matter. Pelleting of broiler litter resulted in significant(P<0.05) moisture evaporation, organic matter reduction and nearly threefold increase of bulk density. Pelleting or molasses addition of broiler litter improved palatability by ‘Hanwoo’ steers and reduced the adjustment period by half(8-9 d).

Objective of this study was to investigate characteristics of inorganic components contained in liquid fertilizer produced using seaweed by adding microorganisms and molasses. Addition of dry yeast to liquid fertilizer resulted in little change in pH and considerable increase in EC with high EC value compared to other liquid fertilizers which have microorganisms additives. Also, it was appeared that the dry yeast-added treatment had higher $NH_4-N$ concentration than other treatments. In the other hand, addition of molasses resulted in low pH compared to the control which has no additives, and EC was not different depending on the amount of molasses. $NH_4-N$ concentration in the 2% molasses added treatment was lowest and it showed a significant difference in the no and 1% molasses added treatments. In conclusion, it was shown that addition of dry yeast to liquid fertilizer increased ammonium nitrogen concentration by accelerating nitrogen mineralization, while molasses has an effect of inhibiting nitrogen mineralization. With application of organic liquid fertilizer containing seaweed increased the fresh weight of chinese cabbage.
