Core Collection Approaches And Genetic Diversity In Flemingia Macrophylla, R. Schultze‐Kraft, M. Peters
Core Collection Approaches And Genetic Diversity In Flemingia Macrophylla, R. Schultze‐Kraft, M. Peters
IGC Proceedings (1997-2023)
Core collections are a useful means to optimise the management, including conservation, of forage germplasm collections. Such optimisation is warranted in view of increasingly limited research resources. As there are several potential options to create core collections, a project is presented in which three approaches are compared: (i) based on germplasm origin information; (ii) genetic diversity assessment by agronomic characterisation/evaluation; and (iii) DNA markers. As example-species for the project, the tropical legume shrub Flemingia macrophylla is selected because of its particular multiple-use potential in smallholder production systems. An important diversity descriptor is the content of tannins influencing feed and litter …

Quality And Nutritive Value Of Mott Dwarf Elephantgrass Silage With Biological Additives, T. Clavero
IGC Proceedings (1997-2023)
This experiment was conducted to study the effects of cellulase enzymes and lactic acid bacteria on the fermentation characteristics, chemical composition and nutritive value of Pennisetum purpureum cv Mott silage. Five kinds of preparation were tested: sugar molasses (control); sugar molasses and cellulase enzymes; cellulase enzymes; concentrate of lactic acid bacteria and sugar molasses and concentrate of lactic acid bacteria. Significant differences (P< 0.05) were found in fermentation quality and chemical composition of control silage as compared to the biological additives treated silage. Addition of cellulase enzymes and lactic acid bacteria resulted in decrease of pH value, cell wall content and increased lactic acid concentration. The biological additives increased silage intake and daily live weight by growing steers.

Plant Secondary Compounds; Their Impact On Forage Nutritive Value And Upon Animal Production, T. N. Barry, D. M. Mcneill, W. C. Mcnabb
Plant Secondary Compounds; Their Impact On Forage Nutritive Value And Upon Animal Production, T. N. Barry, D. M. Mcneill, W. C. Mcnabb
IGC Proceedings (1997-2023)
Both the anti-nutritional and beneficial effects of secondary compounds in a range of temperate and tropical forages have been reviewed. Major secondary compounds in temperate and tropical forage plants occur in the phenolic fraction and include condensed and hydrolysable tannins, phenolic monomers and lignin. Condensed tannins (CT) bind to plant protein by pH-reversible hydrogen bonding. In temperate legume forages this reduces rumen protein degradation and can increase the absorption of essential amino acids (EAA) from the small intestine, with reactivity depending on CT concentration, molecular weight and chemical structure. Low concentrations of CT in Lotus corniculatus (20-40g/kg DM) increased EAA …

Performance Of Promising Forage In Eastern India And Their Nutritive Value, J. J. Gupta, A. Dey, B. P. Bhatt, S. K. Barari
IGC Proceedings (1997-2023)
Eastern region of India possesses large number of ruminant population (162 million) that depend on available feed resources (GOI, 2014). But, at the same time, an acute shortage of green fodder prevails in the eastern part of India that varies from 82 to 89 per cent. The main reason behind this gap is low land holding and negligible area under fodder production. Shortage of quality feed and fodder resources and neglect of forage crops led to decline in the productivity of Indian livestock. However, as a whole, country having 8.30 million ha area under fodder production (Anon, 2013) and out …

IGC Proceedings (1997-2023)
Nutrient intake by grazing animals depends on the amount of dry matter consumed and its chemical composition. Forage grasses, as with any other plants, produce assimilates during the day via photosynthesis to sustain live tissues, plant growth and organic reserves (Taiz and Zeiger 2013). In that context, herbage chemical composition may vary according to variations in the photosynthesis-respiration balance throughout the day. From dawn to dusk the balance increases and herbage dry matter content as well as concentration of soluble carbohydrates increase, the reverse happening from dusk to dawn. That could interfere with nutritive value and nutrient intake of grazing …
