Pasture Heterogeneity Created By Grazing Of Cattle Biotypes With Different Body Size, M S. Cid, M A. Brizuela, M S. Aello, C Ferri
IGC Proceedings (1977-2023)
Cattle grazing leads to the generation of patches differing in forage quality and quantity even in virtually monoespecific pastures. This work assesses the effect of two biotypes of different growth rate and mature body weight on the patchiness of a tall fescue pasture. We analysed height, herbage mass by unit surface, and proportions of heavily and lightly utilized patches through a residual herbage mass gradient generated by both biotypes at four stocking rates from March to December. At the end of spring the residual herbage of paddocks grazed by the small biotype was more heterogeneous. The percentage of heavily utilized …

Forage Productivity And Animal Performance On Different Grass/Legume Pastures For Grazing Management, Sung Seo, Joung Kyong Lee, Dong Eun Shin
IGC Proceedings (1977-2023)
A grazing trial was carried out to determine the effects of different grass/legume pastures on forage productivity, nutritive value, and animal performance. The pasture mixtures were mainly orchardgrass (OG)+ladino clover(T1), mainly OG+alfalfa(T2), mainly perennial ryegrass+alfalfa(T3), and grasses alone (mainly OG, T4). The pastures were rotationally grazed 7 times with growing heifers in 1991 and 1992. The proportion rate of ladino clover in T1 mixtures rapidly increased from 21% up 54 to 68% during the grazing season. However, the rate of alfalfa in T2 and T3 ranged between 12% and 23%. The annual dry matter yield ranged from 9.19 in T4 …
Beef Production From Grazed Grass And Grass/Clover Swards, Edward G. O'Riordan
Beef Production From Grazed Grass And Grass/Clover Swards, Edward G. O'Riordan
IGC Proceedings (1977-2023)
grazed grass (fertiliser nitrogen treated) and grass/clover swards, during two grazing seasons which extended from early-April until mid-November. Both permanent (Treatments A, B and C) and reseeded (Treatment D, E and F) swards were respectively stocked with 3000, 2500 and 2000 kg liveweight/ha in Spring using fifteen steers/treatment (liveweight = 570kg/head). There were small and generally non-significant treatment effects on final liveweight in both years, but heavier carcasses were observed on the reseeded swards (P<0.05). Clover based swards (Treatments B, C and E, F) produced heavier carcasses (P<0.05) than the nitrogen fertilised grass swards (Treatments A and D). Pasture production ranged from 7540 to 10,469 and from 6360 to 11,606 kg DM/ha in year 1 and 2 respectively, with highest yields being observed on the nitrogen fertilised treatment and on the reseeded swards.

Cattle Weight Gain And Sward-Animal Nitrogen Relationships In Grazed Hemarthria Altissima Pastures, L E. Sollenberger, G F. Lima, J F. Holderbaum, W E. Kunkle, J E. Moore, A C. Hammond
IGC Proceedings (1977-2023)
Limpograss (Hemarthria altissima [Poir.] Stapf et C.E. Hubb.) in vitro digestion is greater than most perennial grasses adapted to Florida. Weight gain of cattle grazing limpograss has been lower than expected due in part to low herbage N concentration. Experiments were conducted on limpograss pastures to assess N fertilization, overseeding of the legume aeschynomene (Aeschynomene americana L), and feeding of N supplements to cattle as means of overcoming this limitation. Greater N fertilization, overseeding aeschynomene, and supplementation (corn-urea mixtures) increased weight gain 0.30, 0.23, and 0.24-0.35 kg d-1, respectively, over control treatments. Herbage digestible organic matter:crude protein ratio …

White Clover Content In New Zealand Pastures Affects Milksolids Production, S` L. Harris, D A. Clark
IGC Proceedings (1977-2023)
As a preliminary experiment to measuring milksolids (fat plus protein) production of dairy cattle grazing swards containing different levels of white clover (Trifolium repens L.) nine Jersey and nine Friesian cattle housed indoors during late lactation and fed diets containing either 20, 50 or 80% white clover with the balance perennial ryegrass (Lolium perenne L.). During the first 10 day measurement period cows were fed ad libitum and during the second 10 days feeding was restricted to 75% of metabolisable energy requirement. Milk yields of cows fed 50 and 80% clover were 18% and 10% greater than for …
Pasture Species Effects On Animal Performance, T J. Fraser, S=J S. Rowarth, T L. Knight
Pasture Species Effects On Animal Performance, T J. Fraser, S=J S. Rowarth, T L. Knight
IGC Proceedings (1977-2023)
Increasing concerns about food quality have resulted in investigations into the effects of different forage species on animal production and carcass quality. Pure species plots of high-endophyte ryegrass (Lolium perenne L.), white clover (Trifolium repens L.), chicory (Cichorium intybus L.), plantain (Plantago lanceolata L.) or lotus (Lotus corniculatus L.) were established and lambs grazed the species for 120 days during summer. Pasture species influenced growth rate, hot carcass weight, GR, wool growth, faecal egg counts, adult nematodes at slaughter, and sheep meat odour and flavour. Lambs grazing white clover, lotus or chicory outperformed those grazing …

IGC Proceedings (1977-2023)
Conceptual models of both the metabolisable energy (ME) balance of sheep in relation to the environment and the effects heavy grazing on vegetation and soils will form the basis for the development of a sustainable grazing system for wool production in the Falkland Islands. Research which integrates plant community ecology, agricultural meteorology, sheep energetics, grazing systems and socio-economics is described.
Wool Production From Annual Pastures Intensively Grazed By Wethers In Southern Western Australia, M W. Hyder, A N. Thompson, P T. Doyle, M Grimm, P J. Michael
Wool Production From Annual Pastures Intensively Grazed By Wethers In Southern Western Australia, M W. Hyder, A N. Thompson, P T. Doyle, M Grimm, P J. Michael
IGC Proceedings (1977-2023)
Intensively grazing annual pastures in southern Western Australia to target amounts of feed on offer increased the greasy wool production per hectare three-fold or more compared to production from a setstocked grazing regime. Feed on offer was maintained at 0.8, 1.1, 1.4, 2.0, 2.8 t DM/ha during spring and wool growth per hectare compared to that of sheep set-stocked at the district average of 8 sheep/ha. The role of intensive grazing as a tactic to increase production and profitability of wool producers in Mediterranean environments is discussed.

Milk Production From Ruzi Grass Alone, Ruzi Mixed With Leucaena And Ruzi Supplemented With Dolichos Lablab, S Tudsri, S Prasanpanich, S Swasdiphanich
IGC Proceedings (1977-2023)
Three groups of dairy cattle were compared under different grazing managements viz. strip-grazed on pure ruzi grass (Brachiaria ruziziensis), strip-grazed on mixed pasture between ruzi and leucaena (Luecaena luecocephala) and strip-grazed on pure ruzi and supplemented with lablab (Lablab purpureus). The results showed that the animals that received the legumes through supplementary or mixed with the grass produced higher in daily milk yield (13.63 and 13.26 kg/cow) and fat percentage (4.7 and 4.5) than that of the pure grass alone (12.00 kg/cow for milk yield and 4.2 % for fat). This advantage was due …

Zea Mays Grazing In Cattle Production Systems, V Mundy, B E. Anderson, T L. Gompert, T L. Mader, C A. Shapiro
IGC Proceedings (1977-2023)
Nebraska producers have used silage maize (Zea mays L.) hybrids as a grazed forage in dairy and beef production systems. In an onfarm case study, farmers and researchers collaborated to gather information on production practices, grazing management, and plant characteristics of grazing maize within three forage-based dairy and beef systems. Production practices were generally similar to conventional grain corn production, except that in one system maize was seeded directly into a suppressed grass sod. Milk production from grazing maize was 23 kg/day/animal, compared to 24 kg/day/ animal before using maize and 22 kg/day/animal after using maize. Average gain of …

Grazing Management Of Lotus In Eastern Australia: A Participatory Approach, M J. Blumenthal, J F. Ayers, Z Hochman
IGC Proceedings (1977-2023)
Both Lotus uliginosus Schkukr and L. corniculatus L. require lenient grazing management for persistent production. However, grazing systems, where Lotus is adapted in eastern Australia are based on intermittent set stocking. Conflict between plant ecophysiology and the adverse influences of traditional grazing systems that limit the adoption of new grazing management technology have been addressed by a participatory (co-learning) research and development process. The approach taken involved the use of a facilitator who ran an initial meeting to involve stakeholders and subsequently established “colearning” groups and “co-learning” experimental sites. These sites are monitored, progress is reviewed, and knowledge is …

Tropical Forage Seed Production In Southeast Asia: Current Status And Prospects, C Phaikaew, L Guodao, A Abdullah, M Tuhulele, E Magboo, B Bouahom, W Stur
IGC Proceedings (1977-2023)
The demand for forage seed in southeast Asia has increased in recent years. More than 1,200 tons of seed were produced in Thailand in 1995 with smaller quantities of seed having been produced in China, Lao PDR, Malaysia, Philippines and Indonesia. Large quantities have been produced of Brachiaria ruziziensis, Stylosanthes hamata, Stylosanthes guianensis and Panicum maximum. There are good prospects to increase forage seed production and to develop trade between countries in the southeast Asian region. There is a need to increase seed production of widely adapted species, and expand production of forages for other purposes such as turf …

Forage Production And Performance Of Beef Yearlings Grazing Diploid And Tetraploid Crested Wheatgrass, J D. Bruynooghe, R.D H. Cohen, N W. Holt, P G. Jefferson
IGC Proceedings (1977-2023)
A series of experiments were conducted during 1994 and 1995 at Swift Current, Saskatchewan, Canada to evaluate forage production and animal performance on tetraploid Kirk (Agropyron cristatum (L.) Gaertn.) and diploid Fairway (Agropyron cristatum (L.) Gaertn.) crested wheatgrass pastures under grazing conditions imposed by beef (Bos taurus) yearling steers at four stock density levels (3, 4, 6 and 8 steers ha-1). Total ungrazed forage production for Kirk was greater (<0.05) than Fairway (6302 kg ha-1 vs. 5235 kg ha-1) in 1994 but less (P<0.05) than Fairway in 1995 (3709 kg ha-1 vs. 4633 kg ha-1). Animal performance (average daily gain, animal grazing days and total animal production) did not differ (P>0.05) for steers grazing either Kirk or Fairway pastures. Plant vigour and available energy reserves following one season of grazing were evaluated through etiolated growth with …

Vertical Distribution In Grass Swards: Interactions Between Dry Matter And Nutritional Quality, D R. Buckmaster, R H. Mohtar, S L. Fales
IGC Proceedings (1977-2023)
A field experiment was conducted to study the distribution of mass and quality over plant height throughout the growing season in a pure stand of orchardgrass (Dactylis glomerata L.). When plant density (expressed as kg DM/ha per cm height) is plotted against a height of strata, all treatments show a similar linear shape distribution. ADF and NDF concentrations declined with sward height. Fall treatments had lower ADF and NDF concentrations than summer treatments. Conversely, CP concentrations showed an increase with plant height. Fall treatments showed higher CP than spring and summer treatments. Defoliation management did not affect orchardgrass quality. …

Productivity And Genotypic Diversity Of Trifolium Ambiguum In The Central Caucasian Mountains, Georgia, R G. Patterson, P R. Espie
IGC Proceedings (1977-2023)
Trifolium ambiguum occurred in12 diverse grassland communities, ranging from 1700 m to 2850 m, in the Kasbegi region, Central Caucasus. Total herbage mass in mid summer ranged from 310 to 763 g/m2with T. ambiguum composition ranging from 0.5 to 51%. Maximum T. ambiguum production occurred in fertile, regularly mown hay meadows, but was reduced in severely grazed pastures. It has persisted in these communities after centuries of grazing or cutting, without fertiliser input. T. ambiguum ploidy levels were predominantly diploid (82% frequency of occurrence), often in conjunction with triploid (18%) or tetraploid (27%) genotypes. The triploid T. ambiguum genotype ( …

Nitrogen Nutrition Of Brant (Branta Bernicla L.) Grazing On Saltmarsh And Pasture Species, G Q.A Anderson, M Andrews, S M. Percival, J S. Kirby
IGC Proceedings (1977-2023)
Captive brant Branta bernicla were fed a range of food plants to determine their ability to digest nitrogen and specifically soluble protein. Soluble protein levels in droppings were only a small fraction of those in plants, indicating substantial uptake or conversion. For white clover Trifolium repens L., uric acid content indicated that at least 50% of excreted nitrogen had been metabolised, strongly suggesting that a substantial fraction of soluble protein is utilised by the geese. Carbon/nitrogen ratios increased from plants to droppings while carbon/hydrogen ratios remained nearly constant indicating greater uptake of nitrogen relative to carbon. T. repens was found …

Evaluation Of Morphological, Biological And Chemical Properties For Breeding On New Fodder-Grass Cultivars, S Kozlowski, B Golinska, P Golinski
IGC Proceedings (1977-2023)
Our work is an attempt to emphasize the importance of grass morphological, biological and chemical properties in the process of development of new forage cultivars. Results of our investigations indicate that there are realistic possibilities of developing grass cultivars with improved nutritive properties. However, breeding works can only be effective if a wide range of different properties can be taken into consideration and if, simultaneously, mutual correlations occurring between them are also considered. High mutability of properties revealed by lower taxonomic units of the species observed in Poland indicates that they can constitute a valuable material for breeding work on …

Alfalfa Seeding Patterns And Their Relations With Vegetative And Reproductive Development, R B. Medeiros, A.V A. Jacques, C Nabinger
IGC Proceedings (1977-2023)
This study was conducted to understand how plant density (17, 61 and 89 plants m-2) and row spacing (30 and 90 cm) affect plant development and the consequences on potential seed yield (PSY) and agricultural realized seed potential (ARSP) of alfalfa (Medicago sativa L.) in south Brazil. Both variables were not affected by row spacing but were negatively correlated to plant population. This was a consequence of a higher allocation of assimilates to reproductive structures at low plant competition, denoted by a positive correlation between these two variables and reproductive parts growth rate. Despite the benefits of the low plant …

IGC Proceedings (1977-2023)
The USDA Natural Resource Conservation Service (NRCS) describes and interprets range, native pasture, grazable forest, pasture, and hayland with ecological site descriptions and forage suitability groups. Ecological sites have evolved from agency range and woodland site descriptions, and have integrated alternate and more recent concepts with the traditional succession-retrogression model for site classification and interpretation. Ecological site interpretations are based on vegetation sampling by weight and composition, and other field data collection. Sample data is recorded and managed in the Ecological Site Information System (ESIS) and is analyzed to identify and develop site and suitability group descriptions. ESIS provides data …

Validation Of Arachis Pintoi As A Forage Legume In Commercial Dual Purpose Cattle Farms In Forest Margins Of Colombia, C E. Lascano, G A. Ruiz, J Valasquez, J Rozo
IGC Proceedings (1977-2023)
An on-farm pilot project was initiated in the Andean piedmont of the Amazon basin in Caquetá, Colombia to determine the contribution of the forage peanut Arachis pintoi (CIAT 17434) introduced in degraded pastures to animal production and soil improvement. Early results show that milk production in dual purpose cattle farms can be increased by 20% with A. pintoi-based pastures. However, to enhance adoption of the legume by farmers there is a need to make adjustments on pasture management and assure supply of high quality seed in the region.

A Comparison Of Steer Gains On Cunningham Leucaena And Some Alternative Psyllid-Tolerant Shrub Legumes, R J. Jones, B Palmer
IGC Proceedings (1977-2023)
Five shrub legumes, Leucaena leucocephala cv.Cunningham, L. leucocephala cv.Tarramba, L. diversifolia CPI 33820, L. pallida CQ 3439 and Calliandra calothyrsus CPI 115690 were compared for yield and steer gain in comparison to an all-grass control. Shrubs were sown in rows 4 m apart and all treatments, including the control, were sown with the grass Urochloa mosambicensis cv.Nixon. Edible legume yield was highest for L. leucocephala cv.Tarramba and lowest for L. leucocephala cv.Cunningham. In the absence of psyllid attack, liveweight gains over a 5-week period in summer were highest with cv.Cunningham (1170g/d) and lowest for C. calothyrsus (391 g/d) and the …
Grazing Impacts On The Production Stability Of Fescue Prairie, W D. Willms, J F. Dormaar, J R. King
Grazing Impacts On The Production Stability Of Fescue Prairie, W D. Willms, J F. Dormaar, J R. King
IGC Proceedings (1977-2023)
The fescue prairie in southwestern Alberta is highly productive but susceptible to grazing during the growing season. This study examined how production stability is affected by grazing impact. It was initiated in 1949 using four fixed stocking rates (1.2, 1.6, 2.4, 4.8 animal-unitmonths ha-1). Forage and livestock production were estimated over 4 or 15 years, respectively. The coefficient of variation (CV) for either primary or secondary production was constant over all rates except for the very heavily stocked paddock. Forage production, and therefore livestock production, in that paddock was dependent on precipitation during the growing season. Heavy grazing pressure resulted …

The Effect Of Different Winter Utilization Periods Of A C4 Subtropic Foggage On The Growth Of Weaners, I F. Reckling, G.H J. Kruger
IGC Proceedings (1977-2023)
A significant (P<0.05) increase in lick consumption was found, as winter progressed, which was attributed to a significant decline in the quality (P<0.05) of Digitaria eriantha foggage. Harvested treatments resulted in a significant (P<0.05) decline in residual soil nitrogen levels compared to unharvested treatments. Losses, due to trampling, on average was 21.25%. It is advocated that Digitaria eriantha ought to be utilised in summer and is only suitable for maintenance if utilised in winter.
Leucaena Leucocephala As A Supplement For Goats On Tropical Pastures, T Clavero, R Razz
Leucaena Leucocephala As A Supplement For Goats On Tropical Pastures, T Clavero, R Razz
IGC Proceedings (1977-2023)
A field experiment was conducted in the dryland farming area of Northwest Venezuela in order to evaluate three diets in grazing goats (pasture only; grazing pasture + 0.3 kg of commercial concentrate/ animal/d; grazing pasture + restricted grazing for 2 hours daily in Leucaena leucocephala) on milk production (mp) and milk composition (fat -f- and mineral concentration -mc-). The experiment was laid out as randomized block design. The data showed significant difference (P<0.05) between treatments. Milk production increased in 50 and 70% when goats had access to commercial concentrate or Leucaena graizing as well as grass pasture compared with the control treatment. Milk production in goats with access to Leucaena was insignificantly different than goats on concentrate. Treatments did not affect milk composition. The results suggest that Leucaena leucocephala can supply an adequate amount of nutrient with similar value to commercial concentrate for milk production in grazing goats.
