Comparison Of Composition And Degradation Characteristics Of Early Bloom Alfalfa With Fenugreek (Trigonella Foenum-Graecum) Forages Harvested At Different Stages Of Maturity, Z Mir, P S. Mir, S N. Acharya, L A. Goonewardene
IGC Proceedings (1977-2023)
The objective of this study was to compare the composition and degradation characteristics of early bloom alfalfa and fenugreek harvested after 9, 15 and 17 wk of growth. Crude protein (CP) content of fenugreek cut at 9, 15 and 17 wk was lower (P<0.05) than that of alfalfa. Neutral detergent fibre (NDF) and lignin content of fenugreek harvested after 15 and 17 wk were higher (P<0.05) than that of alfalfa. Ash content was lower (P<0.05) in fenugreek than for alfalfa. In vitro dry matter disappearance (IVDMD) of fenugreek cut at 15 and 17 wk was similar to that of alfalfa. Total in vitro gas production of fenugreek cut at the three stages of growth was not significantly different from those observed for alfalfa. Results indicate that chemical composition and IVDMD of fenugreek at all stages of …

Native Texas Ornamental Bunchgrass Performance Under Water Restrictions, C. Shadrock, K. Hays, E. Green, M. Peoples, S. Gutierrez, C. Segars, A. Chandra, J. R. Bow, J. P. Muir
IGC Proceedings (1977-2023)
Growing human populations and increasing drought conditions compete with ornamental grassland landscapes for freshwater resources. With outdoor use as the largest consumer of municipal water, irrigation restrictions will likely be increasingly implemented, restricting ornamental municipal grasslands. Substituting irrigation-dependent exotic grasses with drought-adapted native bunchgrasses could help mitigate this problem. Greenhouse (GH) trials revealed exotic ornamental bunchgrasses declined faster than natives under progressive water stress, with natives performing best under moderate water with maximum water treatments decreasing aesthetic quality. There was wide variability among accessions, indicating promising genetic diversity from which to select drought resistance for ornamentals. Native grasses performed best …

Comparison Between Geese, Peking Ducks And Mallards In Ability To Digest Common Rye-Grass, H Jeroch, R Timmler, G Guy
IGC Proceedings (1977-2023)
The aim of this digestibility experiment was to observe the differences between geese, peking ducks and mallards to digest common ryegrass (Lolium perenne L.). Adult birds were used for the trials. The grass was frozen after harvesting, stored until the experimental period and fed in fresh constitution. The birds were reared in special single cages and had free access to water and grass. Geese have the best adapted digestive tract of all waterfowl species to consume and digest high-fibre feedstuffs. Peking ducks are able to consume a lot of grass and it seems the digestibility values are similar to …

IGC Proceedings (1977-2023)
Esterase (EST), malic enzyme (ME) and superoxidodismutase (SOD) patterns were studied in 26 accessions of the Vicia sativa aggregate, including V.sativa, V.angustifolia and V.cordata. ME was monomorphic but for EST and SOD intra and interspecific and also intrapopulation polymorphism was detected. An EST marker band was detected for V.cordata. EST patterns did not allow a clear separation between V.sativa and V.angustifolia but SOD patterns grouped the taxa in general accordance with taxonomic classification. The results agree with previous reports on polymorphism in European populations of the aggregate and show that isozymes can be useful genetic markers for the …

The Role Of Leguminous Browse Plants In A Cool Mediterranean Enviornment, P A. Lane, R Reid, D Parsons
IGC Proceedings (1977-2023)
There is considerable scope for improving the productivity and persistence of pasture systems, in the temperate low rainfall zones (< 550 mm annual rainfall) of Australia and New Zealand. Alternative pasture species, including leguminous browse plants, have potential to increase the diversity and stability of these pasture systems. The genus Dorycnium (canary clover), has previously been identified as containing a number of species with desirable forage and soil conservation characteristics. Preliminary investigations have indicated that at least two species, D. rectum and D. hirsutum, produce significant quantities of forage in the year of establishment and are palatable to sheep. It is proposed that these plants may provide a valuable source of forage on land which currently lacks productive and persistent pasture. Forage produced by these plants would be allowed …

Broadleaf birdsfoot trefoil (Lotus corniculatus L.) is a popular crosspollinated, perennial legume cultivated for pasture, or hay and silage production. It does not cause bloat and can be managed to reseed to maintain stands, but significant losses occur when stands decline from disease. Wild birdsfoot trefoil with underground rhizomes was discovered in Morocco. This paper describes research to: 1) compare the morphology and anatomy of rhizomes with aerial stems, 2) determine if rhizomes could be successfully transferred to domesticated germplasm, and 3) determine the inheritance of rhizomes. Morphological and anatomical differences between rhizomes and aerial shoots of five accessions …
