Measures For Increasing The Efficiency Of Hot-Air Drying Of Forage, Siegfried Prufer, Gerd Neubert
IGC Proceedings (1977-2023)
In the GDR, the drying of wilted green forage as well as of whole plants of cereals and grain maize considerably improves the efficiency of hot-air drying as a whole. The processing of wilted crop and the inclusion of whole-plant drying in the drying pattern cause the throughput to increase by 30 to 50% and fuel consurnption per ton of dried crop to decrease by up to 50 %, in comparison with drying of fresh green forage containing 15 to 18 % dry matter. Hot-air drying is particularly suitable for feed production along industrial lines. -Being but little dependent on …

Gdr Standard Plant For Producing Feed Pellets On Straw Basis, Gerheard Schmidt
IGC Proceedings (1977-2023)
Following the international trend, livestock production units are growing in size. Straw, a major feed reserve, must be effectively utilized to meet the growing roughage requirements, especially of ruminants. Therefore, in the GDR a standard feed pelleting plant (type GF A) was developed and put to commercial production. The various machines and equipment employed in the different stages of the GFA pelleting technology are explained in detail. The use of that standard feed pelleting plant shows the advantages of processing straw for semi-finished and finished feeds.

The Efficiency Of Producing And Feeding Complete-Ration Feed Briquets Containing Forage Chop, G V. Blagoveshcheski, V M. Sokolov
IGC Proceedings (1977-2023)
Production of forage chop from a clovertimothy mixture is efficient when harvesting the forage between the shooting of clover (35 to 40 cm stand height) and mid-flowering. For high-temperature drying, each vegetative stage of the plants requires a clearly defined regime. When establishing formulas for complete-ration feed briquets containing clovertimoihy chop harvested before clover budding, the protein/carbohydrate ratio must be balanced by supplementing the ration with 30 p.c. barley meal and 29 p.c. straw; when the mixture was harvested during budding, phosphorus supplementation (one p.c. monocalcium phosphate) is necessary, whilst the mixture harvested during flowering has to be supplemented with …

The Production Of Dry Feeds From Straw And Green Forage In The Gdr, Fritz Berg
IGC Proceedings (1977-2023)
In the GDR, at present about 9% of the feed energy requirement of cattle is covered by dry feeds, above all mechanically processed and chemically treated straw as well as dried green forages. This share is expected to rise to 15 % in forthcoming years. On the basis of technological fundamentals devised by animal nutritionists, corresponding production processes are being developed and perfected. They allow to convert the feedstuffs into a physical and chemical form favourable to high intake; in addition, the feeding value of high-fibre feedstuffs is improved. In this way, the feedstuffs are fed in favourable combination as …

Evaluation And Determination Off Actors Defining The Length Of Thin-Stalked Green Forage Chop, Peter Szendro
IGC Proceedings (1977-2023)
A more exact analysis of the length distribution of chopped material from thin-stalked green forage crops provides more information for the further processing of this material and for comparing the quality of work of the different technologies. Material cut into longer and less homogeneous chop with heavier destruction of the green plant particles shows properties more suitable for further processing than chop harvested with a self-propelled precision-chop forage harvester. In consideration of the special importance of the questions discussed it seems advisable to continue the experiments and to perform them under production conditions as well; the results thus obtained will …

Material And Processing Characteristics Of Grasses And Grass Silages, Manfred Muller, Georg Otto
IGC Proceedings (1977-2023)
Material and processing characteristics are essential initial values for planning of procedures in industrialized crop production. From the technological stages and process sequences from grass mowing to removing the silage, the following key operations can be derived: chopping,. compressing, storing, and removing. For adequate planning of procedures it is necessary to determine the quantitative relations between the essential factors: chopper throughput, proportion of short chop, crude fibre content, and relative final density. A relation suitable for practical application and providing sufficient accuracy is established for estimating the mean dry matter content of a trailer load. If highquality silage is to …

Losses And Stability Of Silage In Dependence On The Degree Of Air Influence, G Weise, H Rettig, G Suckow
IGC Proceedings (1977-2023)
On the basis of model concepts of physical gas exchange, a method has been developed for studying the complex relations existing between the parameters indicating ensilability and the specific local conditions for silage making (degree of anaerobiosis). Conclusions are drawn as to quantitative relations between the depth of the peripheral layers of a silage stock that are endangered by air, the initial density of the silage material, and the sealing of the silage top during the filling and storage periods. Therefrom, certain thresholds can be derived for minimum filling height per day as depending on the initial density of the …

Factors Influencing The Formation Of Effluent In Forage Ensiling, G Peters, F Weissbach
IGC Proceedings (1977-2023)
The amount of effluent formed in ensiling forage crops depends, above all, on the dry matter content of the initial material, on the pressure exerted on the feed stock, and on the kind of crop ensiled. Expected values of effluent amount were derived from model experiments and calculations. Adequate wilting of suitable forage crops will allow to reduce or prevent effluent formation. The degree of wilting required depends on the height of the feed stock and on the kind of silo used. The limit of 30 % DM in initial material, so far generally accepted for effluent formation, only applies …

Decomposition Processes And Effects Of Nitrate In Ensiling Green Forage, Ehrengard Hein, F Weissbach
IGC Proceedings (1977-2023)
Summary As forage production is increasingly intensified, forage batches with increased nitrate content have to be handled. The forage nitrate may be decomposed during the ensiling process. A major portion of the nitrate, however, is retained in stable lactic acid silage. Only spoilt ilages are free from nitrate. Byfar the greater part of the nitrate is reduced to ammonia. Gaseous nitrate decomposition products are produced to only a small extent. They almost exclusively consist of nitrogen monoxide. The formation of ammonia from nitrate was experimentally demonstrated by means of 15N. The reduction of nitrate involved in anaerobic post-fennentation is associated …

Changes Of The Carbohydrate Fraction In Grasses In The Course Of Vegetation And Effects On Fermentability, W Seyfarth, O Knabe, H Arnold
IGC Proceedings (1977-2023)
In experimental ensiling of Dactylis glomerata L., Lolium perenne L., Festuca pratensis Huds., Phleum pratense L., and Lolium multijlorum Lamk., the relations were studied that exist between individual plant carbohydrates and various fermentation products. There was a negative influence of sugars of the galactose group and of pentoses on the formation of silages rich in lactic acid. Growing experiments have shown the beginning of emergence of inflorescences to be the most favourable time of cutting in regard to the fermentability of green forage plants. The experimental results emphasize the necessity of more precisely describing the carbohydrate content of forage plants. …

Investigations Into The Prevention Of The Aerobic DeterioraTion Of Maize Silage, Michael K. Woolford, John E. Cook
IGC Proceedings (1977-2023)
Propionic acid and the antibiotic pimancm have been studied as potential agents for increasing the aerobic stability of maize silage. In separate experiments propionic acid at 1.25 % and pimaricin at 0.026 % of the dry matter stabilized silage for 19 and 13 days respectively, the longest storage periods examined. The influence of these agents in preventing increase in temperature was substantiated by data on microbial populations, losses in dry matter and changes in pH.

New Procedures Of Preserving Beet Tops, Hedvika Maskova, Jiri Havelik
IGC Proceedings (1977-2023)
The possibility was tested of preserving chopped (homogenized) beet tops in experimental tower silos. The treatments without preservatives were compared with treatments using propionic acid (0.5 %) and allylisothiocyanate (1: 10,000). Silage quality, dry matter losses, and secondary fermentation 24, 72, 168, and 240 hours after unloading were determined. Chopping of beet tops was found to have a positive effect on the utilization of the silo volume and on the mechanization of silage handling, and to avoid the need of supplemental compaction. Allylisothiocyanate and propionic acid had a favourable effect on the preservation process and helped to cut losses caused …

Quality Of Feeding Stuffs From Herbage As Influenced By Ensiling And Other Preservation Methods, V A. Bondarev
IGC Proceedings (1977-2023)
Artificial drying is at present the most perfect way of preserving cut herbage. It is not only the most nutrient-saving method, but it also secures best quality of feeding stuffs. In regard to the production cost, however, artificial drying is inferior to the making of wilted silage from herbage. The crop to be made into wilted silage should be wilted down to 50-55 p.c. moisture content. Picking up herbage with a moisture content of 60 p.c. and more is nothing more but an emergency step. The ensiling of grasses with admixture of formic acid gives a feeding stuff equivalent in …

Comparison Off Ormic Acid And A Formaldehyde + Formic Acid Mixture As Silage Additives, Per Lingvall
IGC Proceedings (1977-2023)
Clover-grass silages have been made in tower silos using formic acid or a formaldehyde +formic acid mixture (67: 33) as additives. Untreated controls were included. The storage losses were recorded and the feeding values of the different silages compared in experiments with growing heifers. Both additives decreased storage losses and improved the feed efficiency measured as consumption of metabolizable energy per kg weight gain.

The Effect Of Addition Of Formic Acid, With Or Without Formalin, On The Conservation Quality, Digestibility, Nutritive Value, And Nitrogen Balance Of Direct-Cut Silage, C Demarquilly, Elisabeth Grenet, J P. Dulphy
IGC Proceedings (1977-2023)
From 34 standing crops of grasses or legumes, 93 direct-cut silages were prepared: 33 without additive, 37 with formic acid (3.5 or 5 1/t), 10 with formic acid and 1.5 1/t formalin, 15 with formic acid and 3.5 to 5 1/t formalin. The conservation quality of the silages was improved by the addition of formic acid and even further by the mixture of formic acid and formalin. Silage digestibility is similar to that of the corresponding green forage, but the addition of formalin considerably reduces protein digestibility (by 2 to 8 points). The voluntary intake of silage is lower than …
