Implications And Improvements In Nutritive Value On Plant Performance And Grassland Management, D Clark, J R. Wilson
Implications And Improvements In Nutritive Value On Plant Performance And Grassland Management, D Clark, J R. Wilson
IGC Proceedings (1977-2023)
Lignin modification is one method of improving plant nutritive value and is used to illustrate methods and consequences of plant manipulation. The effect of modifying lignin organ, tissue or enzyme levels on plant performance is inferred from recent scientific work on a range of species. Selection for higher whole plant digestibility is sometimes negatively correlated with plant yield. However, there is sufficient variation in both characters that improvement new not inevitably lead to decreased yield. Cultivars selected for low leaf strength or more digestible stems usually have lesser amounts of sclerenchyma and vascular tissue with less lignin and thinner walls. …

Comparative Study Of Four Varieties Of Cowpea. 2. Nutritive Value And Voluntary Intake, M A. Gabra, K M. Ghobrial
IGC Proceedings (1977-2023)
Pour varieties of cowpea (Vigna spp.) were sown lo study the effect of varieties on nutritive value and voluntary intake by sheep in 4 metabolism trials. Results showed that the feeding value as total digestible nutrients, starch value (SV) and digestible crude protein (DCP) of the different varieties were 63.05-65.61 %, 56.22-58.50% and 12.64-13.08%, respectively. Nitrogen balance was positive with sheep fed green forage. The voluntary intake from SV and DCP by sheep could cover the maintenance requirements from energy and protein with surplus for production.

Genetic Improvement And Nutritive Value Of Lucerne: Crude Protein Content, P Rotili, G Gnocchi, C Scotti
IGC Proceedings (1977-2023)
Stratigraphical analysis of a lucerne (Medicago saliva L.) stand was made to show the effect of leaf age and health, and of leaf-stem ratio, on crude protein content, These data show that when the analysis was made on stems of the same age and on leaves of the same age, health and physiological state, the variability of this trait is negligible, which makes it very difficult to breed for crude protein content. Nevertheless ii is possible to improve the protein content by selection for physiological trails such as leaf persistence and tolerance of early culling.

Plant Improvement: The Evaluation And Extension Processes, A S. Laidlaw, K.F M. Reed
IGC Proceedings (1977-2023)
Registration and evaluation systems throughout the world range from voluntary registration to compulsory schemes involving assessment of taxonomic and agronomic characteristics. Evaluation can be confined to agronomic tests simulated under grazing management or extended to feeding-value trials. Criteria include adaptation to climate and soils, persistence and seasonal growth, annual dry matter production, resistance to pests and diseases, and association with beneficial organisms. The need for stress (e.g. drought, low nutrients, acidity, salinity, heat or cold) to be given more emphasis in programmes in specific localities is suggested. In developing regions the emphasis is screening a wide range of grasses and …

Achievements And Perspectives In The Breeding Of Forage Grasses And Legumes, A.J P. Van Wijk, J G. Boonman, W Rumball
IGC Proceedings (1977-2023)
Successful breeding progrnmmes on forage grasses and legumes have in common that they made seed and plant material of superior genetic and physical quality available to the end-user at competitive prices. This was achieved by government- and privately-funded breeding programmes. A distinction between these two types of breeding organisations is made and discussed. Achievements in various areas are presented and the constraints the breeder is faced with ore given. It is felt that highly advanced genetic designs are not directly applicable, but that progress can continue to be made by applying classical procedures at a greater level of efficiency.

Dry Matter Production And Nutritive Value Of Forage Of Digitaria Eriantha Cv. Irene In Two Locations Of The Central Semi-Arid Region Of Argentina, C A. Frasinelli, H J. Petruzzi, J H. Veneciano, C M. Ferri, V V. Jouve, N P. Stritzler, O A. Terenti
IGC Proceedings (1977-2023)
The aim of this experiment was to compare dry matter (DM) production rates and nutritive value of a warm-season grass, Digitaria eriantha cv. Irene, in two locations of Central Argentina, Santa Rosa (SR) and Villa Mercedes (VM). The plants were established in two identical groups of plots, within a randomized block design. DM rates were calculated from serial, out of phase clippings, and in vitro dry matter digestibility (IVDMD) and crude protein (CP) content analyzed on subsamples. The study lasted for three consecutive growing seasons. Results showed that DM production rates were generally higher (P<0.05) in SR than in VM, but IVDMD and CP content showed no clear trends between both locations. DM production tended to lower from year 1 to 3, related to processes of N depletion from soils (VM) and diminishing rainfall (SR). It is concluded that D.eriantha is a very promising warm-season grass to Central Argentina. Data of nutritive value obtained in one location can be used in others, but results of DM production rates should be taken under the conditions where they will be used.
Separate Harvest Of Leaves From The Stems Of Lucerne Stands, L Schmidt
Separate Harvest Of Leaves From The Stems Of Lucerne Stands, L Schmidt
IGC Proceedings (1977-2023)
Lucerne leaves have significantly higher crude protein and lower crude fibre contents than the stems. The present methods for separating the leaves from the stems have serious deficiencies. Early harvesting, for example, weakens the lucerne stand, and sifting after artificial drying impairs quality. Above that, preparation of leaf protein concentrates is rather expensive. Field trials with a pronged cylinder which strips the leaves from the stems produced leaf yields of ž 80 % with a stem portion of £ 15 % (containing ž 26 % crude protein and £ 18 % crude fibre in the dry matter). Lucerne leaves can …
