High Instantaneous Spring Stocking Rates To Improve Year Round Herbage Utilization In Argentine Dairy Production, M H. Wade, D E. Dalla Valle
High Instantaneous Spring Stocking Rates To Improve Year Round Herbage Utilization In Argentine Dairy Production, M H. Wade, D E. Dalla Valle
IGC Proceedings (1977-2023)
In much of Buenos Aires Province, Argentina 60% of the year’s pasture production occurs during spring. This trial was carried out to test the minimum area necessary for grazing in the period of maximum pasture growth in the 3 to 4 months of spring, so that in turn the maximum potential area for forage conservation could be estimated. At the two levels of herbage allowance aimed for (achieving 18.1 and 36.6 kgDM/cow/d), herbage intake was 11.1 and 13.4 kgDM/cow/d and milk production 20.9 and 22.3 l/cow/d respectively. While these differences were not significant, the trial demonstrated a potential of 70 …

Effects On Intake Of Supplementing Low-Quality Roughage With Protein-Rich Feeds, J.J. M.H. Ketelaars, G A. Kaasschieter, M Kane
IGC Proceedings (1977-2023)
Intake responses of ruminants to supplementation with protein-rich concentrates or legume hays have been related to the ratio of nitrogen (N) content and organic matter digestibility (OMD) of the basal feed. Marginal intake effect of supplements, i.e. change of organic matter intake (OMI) from the basal feed per unit OMI from supplement, decreased on average from 1.7 to 0 and -0.8 g. g-1 at N/OMD of 0.010, 0.016 and > 0.030 g. g-1, respectively. Marginal effect of supplements defined as change of total digestible organic matter intake (DOMI) per g DOMI from supplement was 2.5, 1 and 0.3 g. g-1 for …

The Effect Of Sward Height And Bulk Density On Herbage Intake And Grazing Behaviour Of Dairy Cows, C S. Mayne, D Mcgilloway, A Cushnahan, A S. Laidlaw
IGC Proceedings (1977-2023)
The effects of sward height and bulk density on herbage intake and grazing behaviour of dairy cows during 1 hour grazing periods was investigated. Sward factors had a marked effect on dry matter (DM) intake/bite, which ranged from 0.4 to 1.1 g, and this was reflected in hourly intake rates. Intake/bite was largely influenced by sward height, reflecting increased bite depth in taller swards, with inherent differences between swards at low sward heights largely attributable to differences in bulk density (BD). The results indicate that DM intake rates up to 4.0 kg DM/hour can be achieved in short term grazing …

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 …

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 …

General And Specific Combining Ability In Forage Maize Aptitude Part 2: Land Races, C G. Lopez, L M. Bertoia, R Burak
IGC Proceedings (1977-2023)
Eight argentine land races of maize (1 to 8) were evaluated in a diallel mating scheme for ear, stover and total digestible dry matter yield. For the average of four environments, the crosses 1x2 and 1x4 do not show significant differences with the best check (Cargill Semiden 5) for total digestible dry matter yield. Using the Gardner and Eberhart diallel analysis only the sum of squares of cultivars for stover digestible dry matter yield was significant, suggesting that additive effects are very important in controlling this trait, while for ear digestible dry matter yield both additive and non-additive effects are …

Salix Babylonica, A Traditional Fodder With Promising Potential, K Wangdi, W Roder, P Thinlay
IGC Proceedings (1977-2023)
In Bhutan, tree fodders are important for ruminant nutrition, especially during the dry winter season. Salix babylonica is the preferred species for temperate regions. Farmers above 2000 m plant it widely for fodder, fuel, and fencing. Lack of fodder availability during the dry season, and competition with other crops are its main disadvantages. Crude protein content of S. babylonica leaves declined from 25% in May to 11% in October. Voluntary intake was 78 and 85 g dry matter/W0.75 and live weight gain 330 and 64 g day-1 for growing bulls and sheep, respectively. Dry matter disappearance after 48 hours of …

Differences Between Adapted Populations Of Dactylis Glomerata L. In Argentina, A Andres, M Barufaldi
IGC Proceedings (1977-2023)
Nine adapted populations of orchardgrass (Dactylis glomerata L.) were collected from different grassland environments of Buenos Aires Province, Argentina, in order to investigate genetic differences between and within populations. Fifty plants per population were clonally propagated and transplanted as spaced-plant trial in a randomized design with three replicates. The results indicated large differences between and within populations for most attributes measured. Attributes related with the expression of foliar diseases and seed yield had the highest broad-sense heritability values. The results suggest that the genetic variation found in the adapted populations of orchardgrass has been mainly determined by the environmental …
Soil Nitrification Inhibition With Plantain (Plantago Lanceolata), M. E. Peterson, P. M. Fraser, C. R. Anderson, N. I. Joyce, H. G. Judson
Soil Nitrification Inhibition With Plantain (Plantago Lanceolata), M. E. Peterson, P. M. Fraser, C. R. Anderson, N. I. Joyce, H. G. Judson
IGC Proceedings (1977-2023)
One strategy to reduce nitrogen losses from intensively grazed forage systems is to slow the first stage of soil nitrification, specifically inhibiting the microbial oxidation of ammonium to nitrite. Plantain (Plantago lanceolata) leaves and roots are known to contain several bioactive compounds (e.g., aucubin, catalpol and verbascoside) that may contribute to this inhibition. Recent laboratory studies indicate that this inhibition occurs via consumption by grazing animals of precursor bioactive compounds in aboveground biomass and their subsequent excretion as secondary metabolites in urine and/or via active exudation from the roots. Different cultivars of plantain have been shown to impart …

Complete assemblies of all telomeres, and of ten chromosomes were derived. The chromosome-scale genome size of elephant grass (2n = …
Rangeland-Centered Agroecosystems In Indian Central Himalayas: Operationalizing Ecological Sustainability In Mountain Agriculture, Vir Singh
IGC Proceedings (1977-2023)
Himalayan Mountains are home to unique agroecosystems harboring unique inter- and intra-species diversity in uncultivated and cultivated lands. The uncultivated lands are largely the rangelands which are ecologically more stable ecosystems than the cultivated lands which are ecologically prone areas. Rangelands, cultivated areas, and livestock in mountain agriculture are in organic linkages with each other, woven into a complex unitary whole, functionally oriented to produce foods and other life-supporting products – such as feed, fiber, fuel, fertilizers, etc. – and provide vital ecological functions. Rangelands in fragile Himalayan mountains serve as a key component of agriculture and the biodiversity conserved …

On this basis, Fisher discriminant analysis was used to divide the samples into a training set and test set according to a ratio of 7:3. The spectral characteristic parameters and vegetation indices were used to identify the three main plants and bare land. Results showed that under Fisher discriminant analysis, …
Invasive Annual Grass Issues In Canadian Rangelands, V. Maloney
Invasive Annual Grass Issues In Canadian Rangelands, V. Maloney
IGC Proceedings (1977-2023)
It has been understood for several years now that Canadian grasslands are among the world’s most endangered ecosystems. While the endangerment of the world’s coral reefs and rainforests may make the news more often, the increasingly fast decline of native Canadian grasslands is having a major impact on species diversity as well as global carbon supplies. In this paper, I will discuss the impact invasive annual grasses have had on two important rangeland ecosystems in Canada. Furthermore, strategies for protecting and restoring these invaluable lands will be discussed.
