“…Both of microbes in inoculants were previously reported that those had ability to produce antibacterial substances. In term, L. plantarum secretes bacteriocins substances (Thuault et al, 1991;Gollop et al, 2005;Valan-Arasu et al, 2013) and S. cerevisiae generates oxylipins (Strauss et al, 2005) that those affect Clostridia and fungi inhibition.…”

This study was conducted to determine the effectiveness of inoculants consisted of lactic acid bacteria Lactobacillus plantarum (Lp) and yeast Saccharomyces cerevisiae (Sc) combined with the addition of rice bran on the physicochemical characteristics and palatability of king grass (Pennisetum hybrid) silage. The experiment was arranged in the randomized factorial design (3x3) consisting of the inoculants treatments (control, Lp, Lp+Sc) and the different level of rice bran addition (0, 5 and 10%) which contained 3 replications in each treatment. The measured variables were physicochemical characteristics i.e. color, odor, pH, lactic acid, Fleigh points (quality indication score), and palatability of silage. Inoculation of Lp and Lp+Sc improved silage odor and reduced fungal contamination. Silage treated by Lp+Sc and rice bran (5-10%) resulted in low pH and high lactic acid concentration and Fleigh points significantly (P<0.05). However, the interaction between inoculants and rice bran treatment was not significance (P>0.05). Either inoculation or addition of rice bran tended to enhance the palatability of silage in cattle. It concluded that the addition of inoculants L. plantarum and S. cerevisiae with/without the addition of 5-10% rice bran could improve the physicochemical characteristics of silage and its palatability to cattle.(Keywords: King grass, L. plantarum, Palatability, S. cerevisiae, Silage) (kontrol, Lp, Lp+Sc) INTISARI Penelitian ini bertujuan untuk mengetahui efektivitas penambahan inokulum bakteri asam laktat Lactobacillus plantarum (Lp) dan khamir Saccharomyces cerevisiae (Sc) dengan level penambahan dedak padi terhadap karakteristik fisika, kimia dan palatabilitas pada silase rumput raja (Pennisetum hybrid).

“…One of the ways of using sugar cane as animal feed is as ensilage. The ensilage process is a technique that consists in preserving foddering plants through acid fermentation adequacy, in which lactic acid bacteria convert soluble sugars into lactic acid (10). Although sugar cane silage has been used as a ruminant feedstuff, there is still room to study and improve sugar cane silage (5).…”

Sugar cane silage has a potential for animal feeding, but uncontrolled growth of undesirable microorganisms may cause nutritional losses and affect the animal productivity and health. The objective of this work was to evaluate the microbiological quality and chemical composition of ensiled sugar cane with and without nutritional additives after 30 days of fermentation. Yeasts, filamentous fungi and distinct groups of bacteria were enumerated by plate count methods and the chemical analyzes comprised dry matter, crude protein, fiber content, lignin, and pH. Facultative aerobic bacteria and filamentous fungi were not detected during the fermentative process in any of the treatments. The number of yeasts in five varieties of sugar cane silage without additives was about 6.55 Log CFU g -1 of silage, and with 1% ammonium sulfate and 1% urea were about 5.86 and 5.50 Log CFU g -1 of silage, respectively. The lactic acid bacteria (LAB) count without additive was about 8.62 Log CFU g -1 of silage, and with 1% ammonium sulfate and 1% urea the count was about 6.40 and 6.54 Log CFU g -1 of silage, respectively. The average percent of dry material in the three treatments was 20.76%. The addition of ammonium sulphate and urea has decreased the microbial load after 30 days but it has increased the total crude protein concentration. Additives also affected neutral detergent fiber, acid detergent fiber and lignin content in all five varieties of sugar cane silage.

“…One hypothesis is that speciic strains of LAB interact with microorganisms of the rumen improving their function and animal performance [38][39][40]. Researchers found that LAB from silage inoculants could survive in rumen luid for at least 96 hours, which would allow the probiotic activity [41].Although the efects of LAB inoculant are not well studied, there may be still, the action of a type of bacteriocin that limits the bacterial activity, which can inhibit or harm the microorganism in the rumen [39,40]. Bacteriocins are biologically active proteins produced by LAB that are active against other bacteria, mainly grampositive bacteria as Listeria monocytogenes [42].…”

The intake of DM DMI is determinant for ingress of nutrients to cater to the requirements for animal maintenance and production, principally the intake of protein and energy. The end-products of fermentation can afect the intake of silages and inluence animal performance, since some organic acids negatively inluence the intake of silage and digestibility of nutrients. For example, acetic and butyric acid have large efects on the intake of silage. Ammonia also can negatively afect the intake of silages. The digestibility can be inluenced by end-products of fermentation and change the characteristics of ensiled plants. The objective of this chapter is to explain how silage end-products of fermentation and changes in the structure of forage resulting from the ensiling process can afect the intake and digestibility of silages. Some control mechanisms of silage fermentation can be used to improve the intake and digestibility of silage. Biological or chemical additives may contribute to the increased intake of silage and improve digestibility. Appropriate management techniques can inluence the result.Keywords: acetic acid, ammonia, animal nutrition, butyric acid, forage ensiling . IntroductionEnsilage is the method of forage conservation based on conversion of water-soluble carbohydrates in organic acids by the activity of lactic acid bacteria, which reduces the pH and preserve the fresh forage [1].The ensiling process show advantages such as conservation of large quantities of forage in short time and forage conservation is less weather dependent. However, a disadvantage of the ensiling process is the relative reduction of feeding value of the silage when compared to the © 2016 The Author(s). Licensee InTech.

Although, correct management of silages and use of additives may stimulate the intake of silages and improve the digestibility of silages.The forages may have changes in the nutritive value due to the procedures during production, conservation and post-opening management and biochemical and microbiology phenomena [3]. Besides the conversion of carbohydrates in organic acids occurs by the partial breakdown of proteins, which gives the non-protein structures. These changes depend on the interaction between microorganisms on the material to be ensiled and amount and type of the substrate [4].The silage quality afects the intake and digestibility of ruminants. Basically, the main factors that can interfere with the fermentation of the silage is th...
