Silage Quality

The experiment was carried out to evaluate the possibility of ensiling common vetch - oat mixtures sown at five different seeding rates. Two effects were studied: seeding rate of common vetch and oat in the mixtures and application of bacterial inoculant. The pH, DM (Dry Matter) content, ammonia nitrogen, soluble nitrogen, lactic, acetic and butyric acids were determined on silages. DLG method was utilized for classification the silage quality. Common vetch and oat were grown in binary mixtures at the experimental field of the Institute for forage crops, Krusevac - Serbia, and were tested at five different mixture rates: pure vetch, 25% vetch + 75% oat, 50% vetch + 50% oat, 75% vetch + 25% oat and pure oat. Application of bacterial inoculant affected higher content of ammonia nitrogen and acetic acid (P< 0.05), but lower content of soluble nitrogen (P< 0.05). Depending on the seeding rates of common vetch and oat, 75 : 25 common vetch - oat silage had the highest content of lactic acid and the lowest content of butyric acid. Contents of DM, pH and ammonia nitrogen were similar in all silages ranged from 307.2 to 318.5 g kg-1, from 4.27 to 4.54 and from 16.1 to 19.1% ?N, respectively. According to the DLG method for silage quality evaluation, similar quality grades were founded.

Compositional Quality

Wilting grass before ensiling has become a firmly established practice, since it provides economic advantages due to the increment of the dry matter content of the forage before ensiling. Most forage crops contain less than 20 per cent of dry matter when they are cut thus reduction of the weight of crop to be transported provides advantages (Gordon et al., 1999). Also, research has shown that such practices yield improved and reduced effluent loss from the silo and higher feeding value of the silage. Wilting of grass prior to ensiling has been widely adopted as a means of reducing effluents produced and improving the fermentation quality of silage. The aim of this research was to assess the effect of differing wilting periods and silage moisture levels of silage quality and microbial growth levels.

Silage Quality

The ensiling of soybean and entire maize plant was done in experimental siloses with or without inoculant Sill-All (produced by Alltech inc). The experiment was organized as two-factorial (2 ? 3, n = 3), where factor A was inoculant (a1 = without inoculant, a2 = with inoculant), and factor B was soybean and entire maize plant ratio (b1 = 1: 0; b2 = 2: 1 and b3 = 1 2). Inoculated silages at average had more lactic acid, lower pH values and higher content of ammonia nitrogen, nonsoluble nitrogen and NFE (P < 0.05). The included of entire maize plant in mixture produces high effect on reduction proteolysis. With the increase of entire maize plant share the decrease of pH values and amount of butyric acid, ammonia nitrogen, soluble nitrogen, crude protein and crude fiber was observed. According to the DLG method for silage quality evaluation, silages without inoculant had second class, and silages with inoculant had first class. Improvement in silage quality with the included entire maize plant from fourth to first class, was achieved.

Initial Compaction

To study the effects of compaction and moisture content on ensiling losses, silage quality, and palatability, forage crops ranging in dry matter content from 19.8 to 36.5 per cent were ensiled at initial densities varying from 15 to 44 lb. per cubic foot. These experiments were conducted in 1954 and 1956, using metal silos of half-ton capacity, covered with perforated wood covers.Spoilage was closely related to compaction, decreasing significantly as the degree of compaction was increased, but was not influenced by the moisture content of the crop. Fermentation losses were significantly reduced with increases in either ensiling density or dry matter content.The quality of the resulting silages, as indicated by chemical analyses, was affected by both moisture content of the forage and the degree of initial compaction. Acidity of the silages was highest from the forages of high dry matter and heavy compaction, and showed a significant correlation with fermentation loss. Fermentation losses were also significantly correlated with the ash content of the silage, with increases in crude fibre, and with decreases in dry matter of the material during ensiling.Free choice palatability tests indicated a preference by heifers for the more heavily compacted forages.

This study evaluated silages made with varying proportions of viticulture by-products (VC) and starch extraction from cassava (CSE). It attempted to determine the effects of these proportions on the microbial population, fermentative losses, and chemical composition. The treatments were specified as the proportions of VC in the silage (0 g/kg, 250 g/kg, 500 g/kg, 750 g/kg, and 1000 g/kg). Silages were  evaluated before (0) and after 1, 3, 7, 15, 30, and 60 days of ensiling. The experimental design was completely randomized with five  treatments, six storage times and four replications. The increased level of VC in the silage enhanced its dry matter content, ammonia  nitrogen (NH3-N), and buffering capacity, and reduced organic matter content. Fifteen days after ensiling, additional VC increased the concentration of soluble carbohydrates. The increased level of VC decreased the count of Clostridium spp. and lactic acid bacteria (LAB). The incidence of yeasts and enterobacteria was low in all treatments at all time points. Over time, losses as effluent and gases increased. Use of increasing proportions from VC in silage made with CSE increased the contents of dry matter and soluble carbohydrates and  reduced the fermentative losses of the silage. The increased amount of VC also favoured pH reduction and reduced the proliferation of undesirable yeasts, while increasing the population of LAB.

The authors showed the results of studies of productivity parameters of different early maturing maise hybrids depending on the method of sowing. Experiment included 5 variants: single- seeded hybrids Kubansky 101 and Kubansky 500, Kubansky 101 + Kubansky 500 (50 + 50% of the full seeding rate), Kubansky 101 + Kubansky 500 (25 + 75%) and Kubansky 101 + Kubansky 500 (75 + 25%). The authors carried out a biological yield survey on 10 September. This recording showed that the ultra-early-ripening hybrid Kubansky 101 CB was in the phase of milk-wax maturity of the grain, and the late-ripening Kubansky 500 CB was in the phase of cob formation. In single-species crops, the yields were naturally higher. The late-maturing hybrid yielded 82.0 t/ha, 38.1 t/ha higher than the ultra-maturing hybrid. However, the dry matter yield of the second hybrid was 15.9 % higher, and the cob yield was 29 % higher. The dry matter concentration of the hybrid Kubansky 500 was only 18.8 %. The hybrid Kubansky 101 CB had a dry matter concentration of 34.7 %. Different variations with the ratio of hybrids of different ripeness groups in the sowing showed that in green matter yield, the variants where the proportion of late-ripening hybrid is higher are superior. Thus, the presence of 75% hybrid Kubansky 500 CB allowed obtaining the highest yield of 77.2 t/ha. This yield is almost two times higher than the yield of the single-variety ultra-ripening hybrid (43.9 t/ha). However, the dry matter concentration here was 20.2 %. According to the biochemical analysis of the silage batches harvested, all the forages were benign. No oily acid was detected, and lactic acid predominated over acetic acid. Hay prepared from hybrid Kubansky 101 SV was 33.8% in dry matter content, which compares favourably with silage prepared from hybrid Kubansky 500 SV and mixtures with Kubansky 101 SV. The hybrid Kubansky 500 SV and mixtures with Kubansky 101 SV accounted for 21 % dry matter content. In silage prepared from hybrid Kubansky 101 SV, the percentage of dry matter is 24.2-25 %.

Twenty experimental silages were made from seven pasture species at different stages of maturity. In vivo dry matter, organic matter, and energy ad libitum intakes and digestibilities of the silages were determined with standardized pairs of Merino wethers. The following chemical characteristics of the silages were measured: nitrogen, ammonia nitrogen, total titratable acids, acetic, propionic, butyric, and lactic acids, total volatiles lost during oven drying, lactic acid as a percentage of the total organic acids, pH, acid pepsin dry matter disappearance, dry matter content, and in vitro digestibility and rate of digestion. When all 20 silages were considered, energy intakes on a body weight basis were significantly related to silage pH (r = 0.55) and rate of in vitro digestion (r = 0.58). When the five legume silages were removed from the analysis and only the 15 grass-dominant silages were considered, dry matter intakes were significantly related to acetic (r = –0.57) and propionic acid (r = –0.55) concentrations. Multiple regression analyses did not significantly increase the accuracy of predicting intake. The results suggested that silage intake was negatively related to the degree of fermentation that occurred during the ensiling process.

Gas Tight

Legume–grass forage was ensiled two seasons in 25-ton polyvinyl-encased stacks at dry matter (D.M.) levels of 22 to 37% or stored as field-cured hay. The polyvinyl sleeve coverings provided initial gas-tight conditions. High losses occurred in the high D.M. (32 to 37%) silage during the feeding-out period. Silage quality, as indicated by volatile fatty acid ratios, proximate principles, and digestibility coefficients, was not significantly influenced by D.M. content. When cows were fed the lower D.M. (22 to 29%) silages and hay, forage intake was inversely related to its dry matter content. Intake of high D.M. silage appeared abnormally low. Milk yields appeared to be more consistently influenced by small variations in grain intake than forage dry matter intake through both trials. Milk yields from silages were greater than from hay per unit of D.M. intake. Moisture content of forage had no significant effect on milk composition as indicated by percentage of butterfat, solids-not-fat, or protein.

Thirty-two Holstein steers averaging 369 kg were used to evaluate the feeding value of high moisture barley (HMB). The HMB was harvested at 74.8–77.8% dry matter and ensiled whole in a concrete silo, or was treated with paraformaldehyde or organic acid mixture (propionic 80%, acetic 15% and benzoic acids 5%), and stored on a barn floor. Dry barley (DB) was harvested from the same field at a moisture level of 13.4%. Steers were fed barley ad libitum plus grass silage at the rate of 1.0% of body weight. At feeding, the dry matter content of the DB and HMB was higher than at harvesting. Total nitrogen was higher (P < 0.05) in ensiled HMB and paraformaldehyde-treated HMB compared to DB and organic-acid-mixture-treated HMB. Soluble nitrogen was reduced (P < 0.05) by the paraformaldehyde treatment. Cellulose was not significantly (P > 0.05) affected by any treatments. Daily gain, dry matter intake, feed efficiency, rib eye area, fat over 12th rib, 12th rib fat, bone and muscle were not influenced (P > 0.05) by the different treatments. Carcass yields were significantly (P < 0.05) higher for steers fed DB and ensiled HMB compared to those fed paraformaldehyde- and organic-acid-treated HMB.

 ABSTRAK Ketersediaan hijauan pakan ternak haruslah memenuhi aspek kuantitas, kualitas dan kontinyuitas. Teknologi pengawetan pakan dengan membuat silase berbahan tanaman pakan yang sesuai diharapkan dapat memenuhi kebutuhan pakan tersebut. Sorgum memiliki potensi sebagai bahan silase yang baik namun perlu ditingkatkan kualitasnya dengan menambahkan hijauan yang tinggi kandungan protein kasarnya. Penelitian ini bertujuan untuk mengevaluasi kualitas dan karakteristik fermentasi silase kombinasi sorgum dan leguminosa. Penelitian ini dilakukan dengan mengkombinasikan Stay green dan Indigofera zolingeriana (100:0, 60:40, 50:50, dan 40:60%) sebagai bahan silase untuk dievaluasi pH, kandungan bahan kering (BK), bahan organik(BO), protein kasar (PK) dan Nilai Fleigh. Silase dibuat dalam silo ukuran 1 liter yang difermentasi selama 21 hari. Hasil penelitian menunjukkan bahwa meningkatnya persentase Indigofera zolingerianadalam silase meningkatkan pH silase, BK, dan PK silase. Peningkatan pH tersebut berakibat pada terjadinya proteolisis pada PK silase. Penggunaan Indigofera zolingeriana dalam silase kombinasi dengan sorgum Stay green pada persentase 40% masih memungkinkan untuk memperoleh silase kombinasi yang berkualitas baik (Nilai Fleigh 70,13) dan kandungan protein kasar mencapai 15,68%. Kualitas tersebut selanjutnya akan menurun apabila persentase Indigofera zolingeriana dinaikkan walaupun kandungan protein kasar meningkat.Kata Kunci: Silase, Kombinasi, Kualitas, Evaluasi, Nilai Fleigh.ABSTRACTFeed availability has to meet quantity, quality and continuity aspect. Feed preservation technology by making silage from suitable forage plants is expected to meet these needs. Sorghum has the potential as a good silage material but needs to be improved in quality by adding other forage which have high crude protein content. This study was aimed to evaluate the quality and characteristics fermentation of sorghum and legumecombination silage. This research was conducted by combining Stay greensorghum and Indigofera zolingeriana (100: 0, 60:40, 50:50, and 40: 60% combination) as silage material to be evaluated for pH, dry matter content (DM), organic matter (OM), crude protein (CP) and Fleighpoint. Silage was made in 1 liter size silos which are fermented for 21 days. The results showed that the increasing percentage of Indigofera zolingeriana in silage could increase silage, pH, DM, and CP silage. The increase in pH resulted in proteolysis of silage protein. The added of Indigofera zolingeriana in silage combination at 40% was still possible to obtain good quality silage (Fleighpoint 70.13) and reaching 15.68% of silage CP content. The silage quality was decrease if the percentage of Indigofera zolingeriana increased, even though the silage CP content could increasesafterward.Keywords: Silage, Combination, Quality, Evaluation, Fleigh point
