An Evaluation Of Grazing Value Of Maize And Companion Crops For Wintering Lactating Ewes, E. A. Van Zyl, C. S. Dannhauser Jun 2023

An Evaluation Of Grazing Value Of Maize And Companion Crops For Wintering Lactating Ewes, E. A. Van Zyl, C. S. Dannhauser

IGC Proceedings (1977-2023)

Northwestern KwaZulu-Natal (KZN), in South Africa, is well known for its sheep production from natural rangeland in summer (October to May). During winter, however, the nutritional value of the rangeland cannot maintain young growing sheep or pregnant and lactating ewes. With this in mind, Lyle (1991) suggested the use of planted pastures for the winter. Crichton et al (1998) and Esterhuizen & Niemand (1989) suggested the use of maize crop residues for both cattle and sheep during winter, whereas Moore (1997) evaluated grazing (not harvested) maize for this purpose. He found that the crude protein content of the crop was …

The Use Of Forage Supplements To Overcome Seasonal Shortages Of Grazed Herbage In Dairy Production Systems, A. Hameleers, D. J. Roberts Jun 2023

The Use Of Forage Supplements To Overcome Seasonal Shortages Of Grazed Herbage In Dairy Production Systems, A. Hameleers, D. J. Roberts

IGC Proceedings (1977-2023)

In most dairy production systems, grazed herbage is potentially the cheapest forage resource. However, while the availability is affected by seasonal changes in herbage growth, and/or between year variations in climatic conditions, the requirements of dairy production systems tend to remain constant throughout the season. This paper summarises five experiments that examined the effect of the characteristics of the forage supplement (dry matter, DM; metabolisable energy, ME, content; Type) and the effect of stage of lactation and access method to the supplement on animal performance.

Year-Round Forage Systems For Beef Cows And Calves, J. P. Fontenot, W. M. Clapham, W. S. Swecker, Jr. D. Fiske, J. B. Hall, J. H. Fike, G. Scaglia Jun 2023

Year-Round Forage Systems For Beef Cows And Calves, J. P. Fontenot, W. M. Clapham, W. S. Swecker, Jr. D. Fiske, J. B. Hall, J. H. Fike, G. Scaglia

IGC Proceedings (1977-2023)

Beef cow systems in the USA are based on forages with little or no concentrates fed. Tall fescue (Festuca arundinacea Schreb. L.) is one of the important pasture forages in the lower Northeast and upper South (Allen et al., 2001). Limited research has been conducted on year-round all forage systems based on cool season forages. Stockpiling tall fescue in late summer-early fall provides good quality forage that is usually grazed rather than harvested. Forage systems including tall fescue and clover (Trifolium repens L.) produced excellent performance in beef cows and calves, with minimum inputs (Allen et al …

Alternative Feedbase Systems For Southern Australia Dairy Farms. 3. Economic Returns From Extra Dry Matter Consumption, D. F. Chapman, S. Kenny Jun 2023

Alternative Feedbase Systems For Southern Australia Dairy Farms. 3. Economic Returns From Extra Dry Matter Consumption, D. F. Chapman, S. Kenny

IGC Proceedings (1977-2023)

Growth rates of the 'traditional' perennial ryegrass pasture frequently fail to meet the seasonal feed requirements of herds in non-irrigated dairy systems in southern Australia, leading to a dependence upon additional feed at these times of the year. Farmers commonly purchase this feed off-farm, which can be costly. Growing extra feed on-farm may be more cost effective but will require additional inputs such as N fertiliser and alternative pastures/crops. The gross return to dairy farms of growing extra feed at certain times of the year can be estimated by connecting biophysical models of pasture growth to farm systems models and …

Alternative Feedbase Systems For Southern Australia Dairy Farms. 2. Seasonal Variability, S. Kenny, D. F. Chapman, D. Beca Jun 2023

Alternative Feedbase Systems For Southern Australia Dairy Farms. 2. Seasonal Variability, S. Kenny, D. F. Chapman, D. Beca

IGC Proceedings (1977-2023)

The standard feedbase on non-irrigated dairy farms in southern Australia is perennial ryegrass- dominant pasture supplemented by concentrate feeds, silage and hay to fill seasonal feed gaps. Using models, Chapman et al. (2005) concluded that dairy producers in this region can increase forage consumption and operating profit through the use of summer-active pastures and double-cropping (winter cereal grown for silage, followed by a summer grazing crop). However, these results were based on long-term average pasture and crop growth rates and therefore do not account for seasonal variability associated with climatic variation, which is important in southern Australia. This paper …

Alternative Feedbase Systems For Southern Australia Dairy Farms: 1. Predicted Pasture/Crop Consumption And Farm Financial Performance, D. F. Chapman, S. Kenny, D. Beca Jun 2023

Alternative Feedbase Systems For Southern Australia Dairy Farms: 1. Predicted Pasture/Crop Consumption And Farm Financial Performance, D. F. Chapman, S. Kenny, D. Beca

IGC Proceedings (1977-2023)

Traditional perennial ryegrass-based pastures have significant limitations for efficient feeding of dairy cattle in dryland dairy regions of southern Australia. These include strong seasonality of growth, with 50 - 60% of total annual dry matter arriving in spring and little or no growth during summer. There is clear potential for improving total forage production and the seasonality of forage supply in these regions through the use of alternative pastures (Nie et al. 2004) and fodder crops. This series of papers applies a modelling approach to investigate the potential improvements in farm productivity and profitability resulting from their use.

Seasonal Herbage Accumulation Of Different Dairy Pasture Types In Southern Australia, J. Tharmaraj, D. F. Chapman, Z. N. Nie Jun 2023

Seasonal Herbage Accumulation Of Different Dairy Pasture Types In Southern Australia, J. Tharmaraj, D. F. Chapman, Z. N. Nie

IGC Proceedings (1977-2023)

Perennial ryegrass pastures, which are the mainstay of dairy feeding systems in southern Australia, are characterised by strong spring growth, little summer/autumn growth, and poor persistence. These limitations impose costs to farm businesses through the purchase of additional fodder to fill feed gaps, and regular re-sowing of pastures. The objective of the research reported here was to investigate the potential for alternative pasture types with different seasonal growth characteristics to improve the seasonal distribution of feed supply and overcome some of the limitations associated with perennial ryegrass.

Seasonality Of Forage Production Of Coastcross-1 With Different Sources And Applications Of Phosphorus, José C. Pinto, Í. P. A. Santos, A. E. Furtini Neto, A. R. Morais, E. E. Mesquita, D. J. G. Faria, I. F. Andrade Jun 2023

Seasonality Of Forage Production Of Coastcross-1 With Different Sources And Applications Of Phosphorus, José C. Pinto, Í. P. A. Santos, A. E. Furtini Neto, A. R. Morais, E. E. Mesquita, D. J. G. Faria, I. F. Andrade

IGC Proceedings (1977-2023)

Brazil presents high potential for meat production from pastures. However, the feeding of ruminants depends on the conditions and the climate. Approximately 80% of the annual production of dry matter (DM) occurs in the period October to March (spring - summer). In the autumn and winter production is low associated with high humidity and low temperatures in the south and low rainfall in the tropical north. The situation is exacerbated by inadequate management practices and low soil fertility, particularly low levels of phosphorus (P). The objective of this experiment was to evaluate the seasonality of production of DM of coastcross-1 …

Study On Re-Growth And Nutritional Potentials Of Eleusine Indica L In Chitwan, Nepal, P. R. Regmi, Naba R. Devkota, M. Sapkota, M. P. Sharma Jun 2023

Study On Re-Growth And Nutritional Potentials Of Eleusine Indica L In Chitwan, Nepal, P. R. Regmi, Naba R. Devkota, M. Sapkota, M. P. Sharma

IGC Proceedings (1977-2023)

The efforts to use exotic fodder species to solve the problem of green roughage scarcity in Nepal, have had only limited success because the species are not persistent. Use of local forage species, such as Eleusine indica, which is widely adapted and tolerant of repeated cutting (Lowry et al., 1992), could be possible solution to the problem. The objective of this study was to understand the re-growth potential of E. indica with respect to nitrogen fertiliser application and cutting management and to determine its feeding value in the dry season.

Effect Of Seed Rate Of Trifolium Repens In Pasture Overdrilling, P. Goliński, S. Kozłowski, B. T. Golińska Jun 2023

Effect Of Seed Rate Of Trifolium Repens In Pasture Overdrilling, P. Goliński, S. Kozłowski, B. T. Golińska

IGC Proceedings (1977-2023)

In the region of Wielkopolska, unfavourable climatic conditions, particularly periodical shortage of precipitation, have contributed to a rapid degradation of pastures in dairy farms. In grass-clover mixtures Trifolium repens (Tr) is found to disappear very quickly from the sward. In consequence the DM yield and herbage quality in summer is low. One of the methods of improving of pasture sward and reducing the seasonality of forage production is overdrilling (OD). Many factors affect the success of this undertaking (Sheldrick 2000). This research investigated the response to one easily adjustable factor, that of seed rate (SR).

Tissue Damage And Nutritive Value Of Warm-Season Grasses Following A Freeze, S. W. Coleman, J. Breman, A. S. Blount, K. H. Quesenberry Jun 2023

Tissue Damage And Nutritive Value Of Warm-Season Grasses Following A Freeze, S. W. Coleman, J. Breman, A. S. Blount, K. H. Quesenberry

IGC Proceedings (1977-2023)

Bahiagrass (Paspalum notatum Flugge) is a major forage for livestock in the subtropics of the U.S.A. However, it is subject to freeze damage with minimal winter regrowth, and is generally considered a poor grass for stockpiling due to poor quality of the residue. Bahiagrass genotypes have been found showing a range of leaf freezing tolerance in the in the field (-30 C) (Blount et al., 2001). Other C4 grasses have been reported to have genotype-specific tolerances to below-freezing temperatures ranging from -3 to -100 C (Sakai & Larcher, 1987). This research was begun to try to understand the …

Soil Compaction In Cropland Pastures Used For Winter Grazing, B. F. Tracy Jun 2023

Soil Compaction In Cropland Pastures Used For Winter Grazing, B. F. Tracy

IGC Proceedings (1977-2023)

In the northern United States, forage availability on cool season pastures declines rapidly late in the growing season (Moser & Hoveland 1996). To supplement low forage availability in the fall and winter, producers can graze livestock on cropland pastures containing annual cover crops and crop residues. Managed properly, cropland pastures can provide livestock with abundant, high quality forage that lasts long into winter. A potential issue with cropland pastures is that presence of cattle on moist, non sod-bearing soils could lead to severe soil compaction. The objective of this particular study was to determine how winter grazing on cropland pastures …

The Effects Of Strategic Nitrogen Fertiliser Application During The Cool Season On The Composition Of A Perennial Ryegrass-White Clover Pasture In The Western Cape Province Of South Africa, J. Labuschagne, M. B. Hardy, G. A. Agenbag Jun 2023

The Effects Of Strategic Nitrogen Fertiliser Application During The Cool Season On The Composition Of A Perennial Ryegrass-White Clover Pasture In The Western Cape Province Of South Africa, J. Labuschagne, M. B. Hardy, G. A. Agenbag

IGC Proceedings (1977-2023)

Application of fertiliser N to stimulate DM production of perennial ryegrass-white clover pastures during the cool season can be an important management tool. Application of fertiliser N should however maintain clover contents between 30 and 50 percent (Martin, 1960; Harris, 1994). The aim of the study was to develop a better understanding of the effect of a strategic N fertiliser application during the cool season on the grass-clover balance and to identify possible management guidelines that would maximise dry matter production without suppressing clover content to values lower than required to maintain the benefit of clover in the pasture.

Forage Production And Nitrogen Status In Mixed Fodder Crops, G. Convertini, M. Maiorana, D. Ferri Jun 2023

Forage Production And Nitrogen Status In Mixed Fodder Crops, G. Convertini, M. Maiorana, D. Ferri

IGC Proceedings (1977-2023)

In Southern Italy, the lack of rain during the summer period is one of the main factors limiting fodder crop production. Another very important parameter, linked to drought, is N fertilisation. In these conditions, it is necessary to find mixtures of legumes and grasses able to ensure good production and quality in the driest months, and to rationalise N fertilisation through control of the nutritional status of the crops at the beginning of spring. By this approach, it is possible to adjust N application during the cropping cycle. The aim of this research was to evaluate in a hilly area …

The Use Of Multivariate Analysis In Tropical Grass And Legume Seed Production In Cuban Regions, G. Febles, R. Baños, S. Yáñes, V. Torres, T. Ruiz, F. Funes

IGC Proceedings (1977-2023)

Seed production is an important activity in developing countries where pastures are the main source for animal feeding (Febles et al. 2003). Another outstanding aspect is the mathematical analysis used when a large number of species, varieties and ecotypes are used in the same study. The objective of this paper was to examine the use of multivariate analysis in studies on the effects of edaphoclimatic factors on seed production from tropical grasses and legumes.

Dry Matter Production And Nutritive Quality Of Wild Guinea Grass (Panicum Maximum) Grown Along Roadsides In Sri Lanka, Sujatha Premaratne, G. G. C. Premalal Jun 2023

Dry Matter Production And Nutritive Quality Of Wild Guinea Grass (Panicum Maximum) Grown Along Roadsides In Sri Lanka, Sujatha Premaratne, G. G. C. Premalal

IGC Proceedings (1977-2023)

Wild Guinea grass (Panicum maximum) was introduced into Sri Lanka in the 1820s for forage purposes and has now naturalised in most ecological zones, ecosystems and habitats including roadsides with the exception of hilly and semi-arid parts of the country. The enormous distribution of the grass throughout the country has contributed much to supplying livestock feeds, soil erosion control, and improvement of soil fertility. The objective of this study was to investigate the growth, dry matter (DM) production and nutritive quality of wild Guinea grass along roadsides in different ecological zones.

The Effect Of Topographic Factors On The Productivity Of Mountain Grasslands In Northwestern Benin, T. H. Avohou, Brice Sinsin Jun 2023

The Effect Of Topographic Factors On The Productivity Of Mountain Grasslands In Northwestern Benin, T. H. Avohou, Brice Sinsin

IGC Proceedings (1977-2023)

The Atacora mountains range in northern Benin (660 m altitude) is a special ecosystem in the sudanian zone because of the overriding importance of topographic factors and shallow soils. The vegetation over this mountain range consists of shrub and tree savannas, woodlands and fallows. More and more cattle herds graze on this range. But the functioning of this ecosystem is still unknown like many others in the tropical zone (Sene & Zingari, 2001). This study aims to determine the impact of topography and mountain side exposure on the productivity of the Atacora mountains grasslands in the Atacora mountains.

An Investigation On Ecological Aspects Of Crested And Intermediate Wheat Grasses In Semi-Steppe Vegetation Of Iran, Masoume Amirkhani, Mansour Mesdaghi Jun 2023

An Investigation On Ecological Aspects Of Crested And Intermediate Wheat Grasses In Semi-Steppe Vegetation Of Iran, Masoume Amirkhani, Mansour Mesdaghi

IGC Proceedings (1977-2023)

Crested and intermediate wheat grasses (Agropyron cristatum (L.)Gaertn., Thinopyrum intermedium (H.)Beauv.) are adapted to relatively dry conditions in Iran and have a significant role in providing good forage quality for domestic sheep and wild ungulates in summer rangelands. These grasses occur at altitudes of 1,200 to 1,800 m. A. cristatum is a bunch grass with diverse spikes and medium height (40 cm) and is common on open and exposed knolls, whereas T. intermedium, with height of 115 cm and with long rhizomes, is found in more moist niches in gully bottoms. The objectives of this study were to …

An Eco-Morphological Examination Of Tiller And Stolon Dynamics In A Zoysia Japonica Sward, M. Ito, Y. Ueda, M. Kodama, T. Okajima Jun 2023

An Eco-Morphological Examination Of Tiller And Stolon Dynamics In A Zoysia Japonica Sward, M. Ito, Y. Ueda, M. Kodama, T. Okajima

IGC Proceedings (1977-2023)

Japanese lawn grass (Zoysia japonica), which dominates in grazed semi-natural grasslands in Japan, is being reconsidered recently, because of its high adaptability to poorer conditions and its aggressive creeping habit in open fields. Zoysia has a unique potential for indeterminate multiple-node generation in the stolon tip and differential tiller formation at two tillering sites of every multiple-node (Ta in the bottom node and Tb in the mid-part), so that it displays contrasting behaviour in stolon extension and aerial tiller production in various situations (Ito et al., 2003). In this study, we examined the population structure of various …

Leaf Appearance And Elongation In Panicum Maximum Cv. Tanzania Tillers Of Varying Ages, Domicio Nascimento Jr., Rogério T. Barbosa, Valéria P. B. Euclides, S. C. Da Silva, R. A. Torres Jun 2023

Leaf Appearance And Elongation In Panicum Maximum Cv. Tanzania Tillers Of Varying Ages, Domicio Nascimento Jr., Rogério T. Barbosa, Valéria P. B. Euclides, S. C. Da Silva, R. A. Torres

IGC Proceedings (1977-2023)

A sward may be considered as a tiller population of varying ages and sizes, and these different age groups are likely to present distinct behaviour in terms of growth and herbage production. However, there is very little information on how tiller age, in association with grazing management practices (e.g. frequency and intensity of grazing), alter morphogenetic characteristics and, therefore, herbage production. Against this background, the present experiment had the objective to evaluate leaf appearance and elongation in Panicum maximum cv. Tanzania tillers of different age groups when submitted to intermittent grazing regimes.

Root Density In Panicum Maximum Cv. Tanzania Monoculture And In A Mixture With Leucaena Leucocephala With Different Densities In Mexico, H. J. Delgado Gómez, Luis Ramírez-Avilés, Juan C. Ku-Vera, J. Escamilla Bencomo, P. A. Velázquez Madrazo

IGC Proceedings (1977-2023)

In Yucatan cattle production is limited by forage availability during the dry season. L. leucocephala has good nutritive value (24 - 30% CP) and can stand drought and grazing, therefore its use in mixture with grasses is recommended. However, in association both species could compete for light, water and nutrients. The aim of this study was to assess the effect of introduction of L. leucocephala with different densities on root density of P. maximum.

Comparison Of A Biometric Method With Clipping And Weighing Method For Estimating The Yield Of Artemisia Sieberi (Case Study Zarand-E-Save Region), H. Dianati, M. Abedi, E. Shahriary, Hossein Arzani Jun 2023

Comparison Of A Biometric Method With Clipping And Weighing Method For Estimating The Yield Of Artemisia Sieberi (Case Study Zarand-E-Save Region), H. Dianati, M. Abedi, E. Shahriary, Hossein Arzani

IGC Proceedings (1977-2023)

Forage production is a most important vegetation attribute in rangeland analysis and evaluation and use in management practices. Artemisia sieberi covered about 47% of the rangeland area in Iran and scientists need to know the best method for analysis and evaluation of this species. Clipping and weighing has high precision, but this method is time-consuming and expensive and alternative methods are required. Russian scientists developed a biometric method based on plant dimensions and suggest this method for rangelands in the Middle East (discussed by Dianati, 2003). In America, Muray (1982) used plant dimensions for yield estimation and regression models for …

The Effect Of Nitrogen Fertilisation On The Morphological Development And Growth Rate Of Star Grass (Cynodon Nlemfuensis), P. P. Del Pozo, R. S. Herrera, A. Hameleers Jun 2023

The Effect Of Nitrogen Fertilisation On The Morphological Development And Growth Rate Of Star Grass (Cynodon Nlemfuensis), P. P. Del Pozo, R. S. Herrera, A. Hameleers

IGC Proceedings (1977-2023)

Nitrogen is one of the main inputs used in forage production systems to increase productivity. However, in Cuba, the availability of fertiliser N is limited and therefore if applied, needs to be used with high efficiency. Previous studies (Johnson, 2001, Del Pozo, 2003) investigated the effects of N on growth, carbohydrate and protein content but did not consider morphological changes in Cynodon nlemfuensis. A study was therefore undertaken investigating how N application influences morphological development of the plant and how these changes might affect the efficiency of use of applied N.

Brachiaria And Panicum Productivity At Different Sites Within The Brazilian Amazon, F. F. C. Mello, C. E. P. Cerri, C. C. Cerri, C. A. C. Crusciol Jun 2023

Brachiaria And Panicum Productivity At Different Sites Within The Brazilian Amazon, F. F. C. Mello, C. E. P. Cerri, C. C. Cerri, C. A. C. Crusciol

IGC Proceedings (1977-2023)

Over the last 25 years more than 70 M ha of native vegetation in Brazil have been replaced by pastures for beef production. The substitution of native vegetation on such a large scale with African grasses (mainly of the genera Brachiaria and Panicum) is likely to have an impact on nutrients and organic matter composition, as well as a regional impact on hydrology and water quality.

Row Spacing And Productivity Of Russian Wild Rye Pastures In Semiarid Environments, J. D. Berdahl, S. L. Kronberg, J. R. Hendrickson, J. F. Karn Jun 2023

Row Spacing And Productivity Of Russian Wild Rye Pastures In Semiarid Environments, J. D. Berdahl, S. L. Kronberg, J. R. Hendrickson, J. F. Karn

IGC Proceedings (1977-2023)

To sustain forage yields in dry years in semiarid climates, row spacings >59cm have been recommended for Russian wild rye [Psathyrostachys juncea (Fisch.) Nevski] (Lawrence & Heinrichs, 1968). However, wide row spacings promote weed invasion, soil erosion, and elevated plant crowns resulting in a rough, "washboard" ground surface (Kilcher, 1961). Jefferson and Kielly (1998) suggested a 30-cm row spacing for optimum sustainable forage yields in Russian wild rye in the semiarid prairie region of Canada. This study aimed to evaluate the relationship between row spacing and productivity of Russian wild rye at two semiarid sites near Mandan, in the …

Production And Non-Production Functions Of Grassland In An Upland Region Of Slovakia, J. Cunderlik, L. Gonda, J. Tomaskin Jun 2023

Production And Non-Production Functions Of Grassland In An Upland Region Of Slovakia, J. Cunderlik, L. Gonda, J. Tomaskin

IGC Proceedings (1977-2023)

The importance of grassland lies chiefly in its production of good quality forage that is utilised by cattle and sheep. In upland and mountain regions the non-production functions of grassland such as landscape enhancement or water catchment are especially important. These functions are performed mainly through the sward tillering zone (boundary area between above-ground vegetation and roots) and root characteristics (Jancovic, l985). The objective of this research was to study the biomass above, at, and below ground level of three sward types at different fertilisation levels.

An Appraisal Of The Potential For Soybeans In The United Kingdom, C. A. Sawyer, G. P. F. Lane, W. P. Davies Jun 2023

An Appraisal Of The Potential For Soybeans In The United Kingdom, C. A. Sawyer, G. P. F. Lane, W. P. Davies

IGC Proceedings (1977-2023)

Soybean is a most important crop worldwide, accounting for 56% of world oilseed production and 69% of world protein meal consumption in 2003 (Soystats, 2004). Since their introduction in the early 1800's, forage soybeans have been grown widely in USA. Used originally as a forage crop, this use largely had been forgotten until Dr T. E. Devine (United States Department of Agriculture, Agricultural Research Service; USDA-ARS) released 4 new forage cultivars. Soybeans potentially offer UK farmers a high quality protein source in a short season and also meet the requirements of supermarket chains to remain GM free. This paper aims …
