Forest Grazing In Taiwan, M D. Huang, K J. Chen, Y J. Wu, J C. Yang
Forest Grazing In Taiwan, M D. Huang, K J. Chen, Y J. Wu, J C. Yang
IGC Proceedings (1977-2023)
Due to the shortage of man-power in rural regions, forest grazing was tested as an alternative to eliminate the noxious plants dispersed on the timber plantations in Taiwan. Tree growth was not affected, when Hereford heifers were introduced to 4-year-old Taiwania cryptomerioides plantations(at 1,600 m altitude). Although indigenous water buffaloes were less tolerant to heat than the European cattle( Hereford and Holstein), they were able to show moderate body weight gain in the tough forest environment. Partial blood profiles obtained from buffaloes and cattle gave the same conclusion.
Effects Of Spring Mangement On Herbage Mass And Sward Characteristics In Ryegrass White Clover Pasture, B M. Butler, A.C P. Chu, P.N P. Mathews, C J. Korte
Effects Of Spring Mangement On Herbage Mass And Sward Characteristics In Ryegrass White Clover Pasture, B M. Butler, A.C P. Chu, P.N P. Mathews, C J. Korte
IGC Proceedings (1977-2023)
The effects of grazing intensity and frequency were investigated on a ryegrass/white clover pasture. Large differences in herbage mass between treatments arose mostly from ryegrass reproductive stubble during spring and mid-summer and from dead reproductive stubble during mid-summer and early autumn. Leafy, vegetative pastures were achieved during the reproductive growth period by maintaining a sward residual of less than 500 kg leaf DM/ha (sward height 9 cm) and a grazing interval of less than 14 days (pre-grazing height 20 cm). The evidence suggests that reducing the mass or size of individual reproductive tillers can be equally effective as that of …

An Interdisciplinary Approach For Increasing Yield And Improving Quality Of Forages, J R. Wilson
An Interdisciplinary Approach For Increasing Yield And Improving Quality Of Forages, J R. Wilson
IGC Proceedings (1977-2023)
The contribution of some basic plant disciplines, principally physiology and histology, to the improvement of pasture yield and quality is discussed. Studies of temperate pasture grasses have identified several sources of loss of potential yield and have provided selection criteria for increasing yield. Integration of this physiological research with studies of forage consumption on the same pastures is proving a valuable inter- disciplinary approach to defining management options for maximising pasture and/or animal productivity. In tropical grasses, research towards increasing total dry matter yield is perhaps unwarranted but there is need for more co-operative studies involving plant and animal scientists …
Contribution Of Grassland Science To The Development Of Forage Production And Future Perspectives For Grassland Farming In Japan, H Oizumi
IGC Proceedings (1977-2023)
The utilization of grassland in Japan dates to fairy old times, but its real improvement in terms of industry did not start until the termination of the World War II. As the climatic conditions in Japan differ very much from those of European coutries, the style of grassland farming in Japan is somewhat different from that of Europe. The improvement of grassland farming in Japan after the World War II was divided into four stages, according to the tendency of the number of cattle and the acreage of forage crops. The Japanese Society of Grassland Science was established in 1954. …

Interactions Of Biorational And Synthetic Dmi Fungicides For Control Of Fruit Diseases, Johanna Wesche
Interactions Of Biorational And Synthetic Dmi Fungicides For Control Of Fruit Diseases, Johanna Wesche
All Dissertations
Biological fungicides are increasingly investigated as sustainable alternatives to synthetic fungicides in fruit crop protection. This dissertation examines the interactions between two commercial biological fungicides, Bacillus subtilis AFS032321 (Theia) and metabolites of Pseudomonas chlororaphis AFS009 (Howler EVO); and demethylation inhibitor (DMI) fungicides, with a focus on compatibility, synergistic potential, and resistance implications. In vitro assays revealed that commonly used DMI fungicides difenoconazole, metconazole, tebuconazole, and propiconazole inhibited vegetative growth of B. subtilis at concentrations above 50 µg/ml, whereas mefentrifluconazole promoted colony expansion. Under controlled conditions, lesion development on detached fruit was inhibited synergistically when Theia was combined with the growth-promoting …

Effect Of Cellulase Preparation On Fermentation Of Silage, E No, Y Harasawa, A Ataku, N Narasaki, T Sueyoshi
IGC Proceedings (1977-2023)
The effects of cellulase preparation (Meicelase) on silage fermentation were studied using the first cutting alfalfa and timothy. In one-liter laboratory silos with Meicelase of 0, 0.2, 0.4 and 0:8% of the fresh grasses, the fermentative quality was examined throughout a 30 day ensilage period. The amount of the lactic acid in the silage with the Meicelase was considerably greater than the control silage with no additive. In addition, the pH of that silage was low and the content of water soluble carbohydrate (WSC) was high. However, the differences in the amount of Meicelase applied had no effects in the …

Effect Of Lactic Acid Bacteria On Silage Fermentation, Ph Hellings, G Bertin, M Vanbelle
Effect Of Lactic Acid Bacteria On Silage Fermentation, Ph Hellings, G Bertin, M Vanbelle
IGC Proceedings (1977-2023)
Inoculants were tested to determine their suitability for use as silage aids. Studies carried out in laboratory indicated (1) that the minimum inoculum should be at least 105 viable organisms per gram of fresh fodder and (2) of all bacterial strains tested, only the Lactobacillus and, specifically, L. casei improved storage characteristics. But the efficiency of an inoculant was subordinated to the fermentable sugars content of the crops. In this respect, alfalfa and second cut grass had the lowest potential for ensilage. Energy was supplied as a mixture of milled barley and amylolytic complex. The influence of a 1: 1: …

Ensilage Of Alfalfa Press-Cake. A Kinetic Model For Ph, Acidity And Nitrogen Evolution, G Amdrich, L Lencioni, R Florentini, G Anelli
IGC Proceedings (1977-2023)
A kinetic model to describe the time evolution of pH, acidity, metabolizable nitrogen and k1 • B, ( a function related to the bacteria concentration) during ensilage of alfalfa press-cake is suggested. The basic hypotheses of the model are given together with the related differential and integral equations. The kinetic model has been tested using experimental data obtained from two samples of alfalfa press-cake respectively ensiled with and without acid addition. The correlation coefficients obtained indicate the reliability of the suggested model.

IGC Proceedings (1977-2023)
Research at Ruakura has aimed at improving the economics of lucerne protein extraction, by extracting more of the protein (up to 85%) and by searching for ways to get maximum value for each of the components in the lucerne. Presently most lucerne protein concentrate is sold on the basis of its protein and xanthophyll contents, which are valued by poultry growers. Other components, including carotene, chlorophyll and vitamin E, are not valued in poultry feed and consequently could be extracted and sold separately. Carotene and vitamin E have recently been associated with cancer prevention. The paper also discusses the value …
Effect Of Drying Methods On The Nutritive Value Of Leaf Protein Concentrates Coagulated By Acidification, Heat Or Anaerobic Fermentation, M Ohshima
IGC Proceedings (1977-2023)
SUMMARY To determine the effect of heat-treatments on the nutritive value of leaf protein concentrate(LPC), several LPCs prepared by different procedures were fed to rats. The nutritive value of ladino clover LPC separated centrifugally from acidified juice and freeze-dried was compared with that of LPC prepared from the same acidified juice by heating to 70°C with an electric heater before the centrifugation and oven-dried at 70°C. The heat-treatments reduced not only the apparent digestibility of crude protein by 5%, but also the nutritionally available lysine content of LPC. Response of rats to lysine supplementation in addition to methionine was observed …

Alkali Treatment Of Rice Whole Crop Silage, T Tobino, N Mikami, A Yamazaki, R Kobayashi, K Furugouri
IGC Proceedings (1977-2023)
Application of Na OH for rice whole crop at the time of ensiling increased digestibility, intake and body weight gain of Holstein steers. As rice whole crop silage is inclined to cause secondary fermentation, when the moisture content is not sufficient, water addition to the filling material is necessary. The suitable application level of NaOH is 3 to 4% of silage dry matter and it can be applied successfully using 20 to 30% solution. The rate of notreacted Na in the NaOH applied silages was 20 to 40% and it changed wholly to the form of Na2CO3 -Na. The greater …
The Effect Of The Harvest Time, Height And Length Of Cutting On The Quality And Nutrient Yield Of Japanese Millet Silage, T Nakui, N Yahara, S Takai
The Effect Of The Harvest Time, Height And Length Of Cutting On The Quality And Nutrient Yield Of Japanese Millet Silage, T Nakui, N Yahara, S Takai
IGC Proceedings (1977-2023)
The experiments were made to determine the appropriate harvest time, height and length of cutting of Japanese millet for silage. Harvesting the millet at the end of the late dough stage was found to be the most favorable for silage, and the fermenting quality of the silage was improved by higher cutting and keeping the length of the cutting short ( < 10 mm). Dry weight yield of the plant (x) well correlated with TDN yield (Y) of the silage (r = 0.91, Y = 0.511x - 64.7). A negative correlation was obtained between the rate of temperature rise during the second fermentation process of silage broken the seal and the content of butyric acid in the silage. The second fermentation was suppressed when the butyric acid content in the total acid of the silage was more than 3 % .

Effect Of Stage Growth And Chopping Length On Ensiling Characteristics, Digestibility And Palatability Of Guinea-'A', S Panditharatne, J P. Fontenot, V G. Allen, M.C N. Jayasuriya
IGC Proceedings (1977-2023)
Ensiling of forages is a common practice in temperate areas, but is not used extensively in tropical countries. Preservation of excess forage during rainy seasons would provide a more even distribution of feed during the year. Experiments were conducted to investigate fermentation characteristics, and digestibility and palatability of Guinea-'A' (Panicum maximum, ecotype A) silage by sheep. Guinea-'A' grass was harvested after 2- and 3-week growth periods, and ensiled chopped or unchopped in 210 liter metal drums, double lined with polyethylene. Cutting grass at 2 weeks decreased pH and increased lactic acid of silage, compared to cutting at 3 weeks. Chopping …
