An Interdisciplinary Approach For Increasing Yield And Improving Quality Of Forages, J R. Wilson 2025 CSIRO

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 2025 Chiba University

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. …

Diseases caused by vector-borne plant pathogens cause adverse impacts on yield resilience, food security, and farmer livelihoods, which are bound to aggravate under global change. Biological control is routinely discounted as a mitigation strategy for plant diseases, partially due to scarce and inconclusive empirical support. Here, using curated field survey data for 58 persistently or semi-persistently transmitted pathogens, we employ a multi-method approach to assess the role of resident (i.e., naturally occurring) biological control agents in these pathosystems. Our meta-analyses show how in planta pathogen incidence is strongly affected by vector abundance and infectivity. Meanwhile, biological control agent density negatively …


Six Lineages Of Cercospora Are Responsible For Cercospora Leaf Blight And Purple Seed Stain On Soybean In Brazil, Leandro Luiz Borges, Thiago Freitas Ferreira, Marina Garofalo Lana, Isabela Delpupo Caliman, Newton Deniz Piovesan, Burton H. Bluhm, Luiz Orlando de Oliveira 2025 Universidade Federal do Parana

Six Lineages Of Cercospora Are Responsible For Cercospora Leaf Blight And Purple Seed Stain On Soybean In Brazil, Leandro Luiz Borges, Thiago Freitas Ferreira, Marina Garofalo Lana, Isabela Delpupo Caliman, Newton Deniz Piovesan, Burton H. Bluhm, Luiz Orlando De Oliveira

Plant Pathology Faculty Publications and Presentations

The genus Cercospora is widely distributed and causes foliar diseases, including those affecting soybean. Cercosporoid species exhibit high intraspecific variation, and the lack of distinct morphological features has led to host plant association becoming a key criterion for species delimitation. Recently, in addition to C. kikuchii, other species such as C. cf. flagellaris, C. cf. sigesbeckiae, and C. cf. nicotianae have been linked to Cercospora Leaf Blight (CLB) and Purple Seed Stain (PSS) in soybean. In this study, phylogenetic and phylogeographic analyses were used to identify six Cercospora lineages responsible for causing CLB and PSS across Brazil. A total of …


Interactions Of Biorational And Synthetic Dmi Fungicides For Control Of Fruit Diseases, Johanna Wesche 2025 Clemson University

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 …

The Effect Of Cellulolytic Enzyme Preparations As In Vitro Improvement For Forage Digestibility, G Bertin, Ph Hellings

IGC Proceedings (1977-2023)

The systematic study of commercial preparations of fungal cellulases has been undertaken with the aim of determining the principal components and the contribution of each to the digestion of the plant cell wall. These enzymes, normally have three fold role-silage preservative by hydrolysing the cellulosic wall of plant material, cellulases make available fermentable sugars to the lactic bacteria. -Improvement of digestibility we can increase gain by 1 % of the dry matter in forage. - Improvement of intake if the animal digests more quickly his gut will empty more rapidly thus making it available sooner for a new intake of …


Effect Of Cellulase Preparation On Fermentation Of Silage, E No, Y Harasawa, A Ataku, n Narasaki, T Sueyoshi 2025 Rakunogakuen University

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 …


Effects Of Sample Drying Method On Estimates Of Nutritive Value Value, S Uchida, H Hayashi, T Horigome 2025 Okayama University

Effects Of Sample Drying Method On Estimates Of Nutritive Value Value, S Uchida, H Hayashi, T Horigome

IGC Proceedings (1977-2023)

The influence of different drying methods for the sample used for analysis on the estimates of the nutritive value of silage was investigated. The silages and hay were made from the same grass and fed to three wethers to determine digestibilities. The samples for analytical use of silages and hay fed, and feces excreted, were prepared by three drying techniques of freeze drying (F), oven drying at 60 C (L) and oven drying at 100 C (H) and then each dried sample was ground in a Wiley mill to pass a 0.5 mm screen. The residual moisture in prepared samples …


Effect Of Lactic Acid Bacteria On Silage Fermentation, Ph Hellings, G Bertin, M Vanbelle 2025 Catholic University of Louvain

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 2025 University of Pisa

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.


Ensilage Of Alfalfa Press-Cake, G Anelli, G Andrich, M Contini, L Lencioni 2025 Viterbo University

Ensilage Of Alfalfa Press-Cake, G Anelli, G Andrich, M Contini, L Lencioni

IGC Proceedings (1977-2023)

The Istituto Industrie Agrarie of the University of Pisa has developed a wet green crop fractionation process which involves the ensilage of the press-cake. This note reports some experimental results on the alfalfa press-cake ensiled with or without addition of acid. The evolution of silages was evaluated through organoleptic and chemical parameters. The good behaviour· during the ensilage shows that alfalfa press-cake is suitable to be ensiled even without previous acidification.

Coagulation Of Sheep Milk Added With Alfalfa Juice And Protein Concentrate, L Lencioni, R Florentini, A M. Pisanelli, C Galoppini

IGC Proceedings (1977-2023)

This note reports some experimental results on the preparation of food-grade products obtained by enzyme coagulation of sheep milk added with alfalfa juice, decolourized whole protein concentrate and cytoplasmic protein concentrate. Working conditions are reported together with the yields, chemical composition and organoleptic properties of the coagula. Products obtained from milk supplemented with low alfalfa juice (��5% dry basis) or protein concentrates (;;;;:10% dry basis) show a good acceptability. The ripening greatly reduces grass flavour and taste.

Effect Of Remaining Brown Juice In Wet Protein Curd On The Quality Of Leaf Protein After Drying, Y S. Cho, J K. Kim, T Horigome, S Uchifa

IGC Proceedings (1977-2023)

The influence of remaining brown juice ( deproteinised juice) in wet protein curd on the quality of resulting leaf protein was examined. Freshly cut Italian ryegrass and red clover were fractionated into protein curd, brown juice and pressed cake. Various leaf proteins were prepared by drying the protein curds retaining different amounts of brown juice at 65°C followed by acetone-washing, and by immediate acetone-washing of the protein curd. Casein-brown juice mixtures at the ratio of 1 :3 and 1: 6 were also prepared. The crude protein content of the dry matter in brown juice was very low, 9. 9% for …


The Nutritive Value Of Mixtures Of White Leaf Protein And Other Food Proteins, R Carlsson, P Hanczakowski 2025 Lund University

The Nutritive Value Of Mixtures Of White Leaf Protein And Other Food Proteins, R Carlsson, P Hanczakowski

IGC Proceedings (1977-2023)

The nutritive value of white leaf proteins were studied, as food supplements. The protein was obtained by heat­fractionation ( Chenopodium quinoa Willd.) or by de-pigmentation (Medicago sativa L. ). The leaf protein was substituting 50% of the protein in a diet, where the remaining 50% came from wheat gluten, soya bean meal, bone-meat meal, fish meal, skim milk or whey. The nutritive value was estimated by the Thomas-Mitchell nitrogen balance method. The proximate chemical composition of the food protein products, and their amino acid composition were analysed. In every mixture but the one with gluten the biological value was higher …

IGC Proceedings (1977-2023)

With the purpose of searching physiological active component(s) contained in alfalfa leaf, green leaf protein concentrate (LPC) and brown juice were tested against the effects on the inutagenicity of mutagen and hyperlipemia. LPC and brown juice were found to inactivate the mutagenicity of 2•aminoanthracene by the Ames test, and the capacity was more powerful in LPC than in brown juice. Further feeding of alfalfa LPC or its brown juice added diet to hamster reduced the total cholesterol and triglyceride levels in serum.


Influence Of The Age Of Chicken On The Metabolizable Energy Value Of Alfalfa Leaf Protein Concentrate, S Terapuntuwat, I Tasaki 2025 Nagoya University

Influence Of The Age Of Chicken On The Metabolizable Energy Value Of Alfalfa Leaf Protein Concentrate, S Terapuntuwat, I Tasaki

IGC Proceedings (1977-2023)

Influence of the age of chicken on the nitrogen corrected metabolizable energy (MEn) value of alfalfa leaf protein concentrate (LPC) was investigated. Chickens of various ages were fed diets containing certain amounts of the LPC, and droppings were collected quantitatively. The MEn of the diets was determined as the difference between consumed energy and excreted energy which was corrected with retained energy as body protein. Then the MEn value of the LPC was calculated using the values of the LPC containing diets and that of cornstarch which was obtained from data for a LPC-free diet. As a result, the MEn …

High Value Productions From Lucerne: A New Zealand Perspective, R M. Mcdonald, P E. Donnelly, R A. Mills, S R. Vaughan

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 …
