Integration Of Wildlife And Cattle On Communal Lands In Kangwane, South Africa, M Stalmans, A Van Wyk, M T. Mentis
Integration Of Wildlife And Cattle On Communal Lands In Kangwane, South Africa, M Stalmans, A Van Wyk, M T. Mentis
IGC Proceedings (1977-2023)
The feasibility of integrating wildlife with the current livestock husbandry on communal lands in KaNgwane was investigated. Present stocking rates were 3 times the recommended figure for production farming. This fitted predictions based on the Jones-Sandland model for populations where the major consideration is maximum number of animals rather than high productivity. The integration of game was seen as a means to increase economic output, while spreading benefits from the use of natural resources to the community at large and establishing a form of ecologically sustainable land use. The active involvement of the community in the planning process and their …
Game Production On Private Land In South Africa, J C. Pauw, M J.S Peel
Game Production On Private Land In South Africa, J C. Pauw, M J.S Peel
IGC Proceedings (1977-2023)
The game industry on private land in South Africa has grown considerably in the last 30 years, resulting in a greatly increased biodiversity on private rangeland. However, animals are not domesticated and management is difficult. Management becomes even more complex because commercial game production normally involves a number of species, including domestic stock, in the same production system. Mixed livestock-game ranching holds certain advantages for management and is generally perceived to be more profitable than either alone. Because of human preferences, a lack of clearly defined management objectives and lack of practical management recommendations, veld is generally heavily utilised and …
Overcoming Limitations On The Productivity Of Browsing Ungulates In Africa, Norman Owen-Smith
Overcoming Limitations On The Productivity Of Browsing Ungulates In Africa, Norman Owen-Smith
IGC Proceedings (1977-2023)
In African savannas primary production by woody plants may match that by the grass layer. However, maximum population levels attained by browsing ruminants are only one tenth of those reached by similar sized grazers, The productivity of browsers is limited because (I) much foliage is out of reach, and dispersed by wind when shed; (2) most palatable trees are deciduous, leading to a food bottleneck during the late dry season; (3) leaves of many woody species are rendered unpalatable, indigestible or toxic by plant secondary metabolites. Management actions to overcome these limitations include (I) lopping trees to restrict their height; …
Economic And Ecological Features Of Livestock And Wildlife Utilization In Africa, J I. Barnes
Economic And Ecological Features Of Livestock And Wildlife Utilization In Africa, J I. Barnes
IGC Proceedings (1977-2023)
This paper looks at livestock and wildlife utilisation in Africa within the framework of total economic value (TEV), which includes both utilisation and biodiversity values. In Africa, traditional use of wildlife involves open access systems on public land, Here, free ranging, public wildlife resources are used to produce subsistence or marketed meat and skins at smaII scale. Traditional livestock systems involve open access use of rangelands. Here, livestock are kept at small ·scale to produce draft power, milk, meat and as a store of .value. Commercial use of wildlife involves restricted access systems on both public and private lands. Here, …
Conservation Of Biodiveristy In Managed Rangelands, With Special Emphasis On The Ecological Effects Of Large Grazing Ungulates, Domestic And Wild, Patrick Duncan, Peter J. Jarman
Conservation Of Biodiveristy In Managed Rangelands, With Special Emphasis On The Ecological Effects Of Large Grazing Ungulates, Domestic And Wild, Patrick Duncan, Peter J. Jarman
IGC Proceedings (1977-2023)
Biodiversily with its different components (genes, species and ecosystems) is defined in relation to rangelands, whose Importance in its conservation is described. At the fine scale grasslands are much more diverse than tropical rain forest, and are comparably diverse at a regional scale, at least in Africa. Rangelands are crucially important world wide for 1he conservation of plants, and also for birds and large mammalian herbivores. Large ungulates (and other large herbivores) ace "keystone" species in these·ecosystems, playing a crucial role in the maintenance of diverse communities of plants, birds and invertebrates associated with such grasslands. Modification of the natural …

Productivity Of Silvipastoral Areas And Management Needs In Arid Regions Of India, N C. Jain
IGC Proceedings (1977-2023)
In an extremely arid state of India (Rajasthan) having high livestock concentration and vast degraded lands, the State Forest Department has developed community and forest lands into silvipastoral areas by sowing grass (mainly Cenchus ciliaris and C. setigerus) in association with trees. Surveys have revealed high variability in pasture establishment and productivity in different regions. Cenchrus established well in most regions, except the extreme south, if proper sowing methods with closer spacing were followed and soil conservation measures undertaken. Closure from animals helped in favourable grass succession. Establishment of Dichanthium annulatum and Stylosanthes hamata was relatively poor, Analysis of …

Sheep And Forage Productivity In Rubber Plantations, I Tajuddin, D T. Chong, K F. Ng, W W. Stur, H M. Shelton
IGC Proceedings (1977-2023)
The concept of integration of sheep with rubber plantations for weed control and meal production is rapidly gaining recognition in Malaysia. A series of experiments were set up with ACIAR support to determine the level of forage and animal production achievable in rubber plantations and to introduce and evaluate new forage germplasm for sheep grazing under rubber. These experiments showed that (i) the productivity of the currently used cover crops and naturally occurring further as rubber trees matured, (ii) the proportion of the unpalatable cover crop Caloponuim caeruleum increased rapidly with sheep grazing in immature rubber, (iii) reasonable sheep live-weight …
Pastures As The Secondary Components In Tree-Pasture Systems, Chin Peng Chen
Pastures As The Secondary Components In Tree-Pasture Systems, Chin Peng Chen
IGC Proceedings (1977-2023)
The multi-stata canopy structure of rain forest allows only I% sunlight penetration, too little for the survival of forage beneath it. However, man-made forest plantation (rubber, oil palm and coconut) allows more light for forage species. Initially, 60-70 forage species were recorded under these modified forest canopies but only one third of them survived heavy shading. Forage dry matter yields declined from 2.8-4.8 I/ha DM at immature phase of plantations, to 0.1-1.0 I/Im at mautre phase. Nutrients. available to grazing animals from forages under plantations were guile high (18.4 kg Nit DM and 5609 MJ MEit DM) from native forages, …
Grazing Potential Of Desiccation-Tolerant Tropical And Subtropical Grasses, Y A. Sutaryono, D F. Gaff
Grazing Potential Of Desiccation-Tolerant Tropical And Subtropical Grasses, Y A. Sutaryono, D F. Gaff
IGC Proceedings (1977-2023)
Some desiccation-tolerant grasses possess the potential for use as a grazing source for animals. Some species compared favourably in nutrient content and digestibility with other tropical animal fodder grasses. The Sporobolus species, S. aff, fimbriatus, S. lampranthus, S. pellucidus, together with Eragrostis invalida and Eragrostiella nardoides showed the most promising combination of desirable characteristics. Resurrection grasses contained potentially toxic substances, but, it appears, in amounts harmless to animals, Animal feed trials are needed to test their real feed value, palatability and non-toxicity to animals.

Mixed-Species Grazing In The Highland Sourveld Of South Africa: An Evaluation Of Animal Production Potential, M B. Hardy, N M. Tainton
IGC Proceedings (1977-2023)
The effects of mixed-species grazing, at 5 cattle to sheep ratios all at the same stocking rale, on individual animal mass change/ ha mass change/ Ila were monitored for 2 grazing seasons, The ratios were balanced in terms of animal units which equate the expected intake of cattle and sheep. The study was conducted on a humid grasslands in which the herbage characteristically loses quality as Jt mature1. Mass gains of individual cattle were higher when the cattle grazed 10ge1her with the sheep than when they grazed alone. This was ascribed to increasing herbage availability as the ratio of cattle …
Prediction Of Live-Weight Gain Of Cattle Grazing Pastures On Brigalow Soil, M Hirata, C K. Mcdonald, R M. Jones
Prediction Of Live-Weight Gain Of Cattle Grazing Pastures On Brigalow Soil, M Hirata, C K. Mcdonald, R M. Jones
IGC Proceedings (1977-2023)
A model for predicting the live-weight gain-(LWD) of cattle from climatic conditions and pasture and cattle attributes was developed. The model was calibrated and validated against the data from a long-term grazing experiment on brigalow soil, sown with green panic pastures. When validated, the model tended to overestimate LWG as the proportion of green panic (Panicum maximum var. trichoglume) in the pasture decreased, because the model was calibrated, without considering species composition, to data from years when green panic was dominant. This study emphasises the limitations of empirical models of grazing systems. The study also implies that there …
Animal Feed Research In Eastern And Southern Africa: Historical And Actual Priorities, Samuel C. Jutzi, J C. Tothhill
Animal Feed Research In Eastern And Southern Africa: Historical And Actual Priorities, Samuel C. Jutzi, J C. Tothhill
IGC Proceedings (1977-2023)
A review of animal feed research reports from 7 countries of eastern and southern Africa is used to assess historical and actual research emphases. Priority was on feed supply and evaluation for cattle production with strong rangelands improvement programmes. Most research focused on ecologically favoured regions and larger-scale livestock commodity production. Strong efforts for the exploitation of grasses for improved feed supply were supported by legume work for feed quality improvement. There was a strong emphasis on feed agronomy work, one third of all that work involving animals. Component research results were reported with little discussion of target systems implications, …
Animal Production And Dynamics Of Pangola Grass, Ryegrass, And White Clover As Influenced By Grazing Pressure, A De Moraes, G E. Maraschin
Animal Production And Dynamics Of Pangola Grass, Ryegrass, And White Clover As Influenced By Grazing Pressure, A De Moraes, G E. Maraschin
IGC Proceedings (1977-2023)
A grazing experiment was conducted at the Estacao Experimental Agronomica - UFRGS, Eldorado do Sul, RS, from June 1989 to March 1990, to evaluate a mixed pasture of pangola grass (Digitaria eriantha), ryegrass (Lolium multiflorum) and white clover (Trifolium repens) under 4 levels of grazing pressure (GP), namely: 3.S, 7 ,0, 10.5 and 14.0 kg DM of forage on offer /100 kg live weight (LW), with 2 field replications. Average live-weight gain (LWG) decreased as grazing pressure increased. Maximum LWG was obtained at grazing pressures of approximately 12%, which was associated with DM residues …

Cultivated Pasture, Forage On Offer And Animal Responseg, G E. Maraschin, A De Moraes, L.F. A. Da Silva, J Riboldi
IGC Proceedings (1977-2023)
Animal gains on pasture are influenced by the forage dry mailer on offer (DMO). To ascertain this relationship a pangola grass (Digitaria eriantha) pasture was evaluated under forage DMO levels of 3.5%, 7.0%, 10.5% and 14.0% of live weight (LW)/head/day. Two steers were assigned to each treatment as tester animals plus a number of put-andtake steers to maintain the desired levels of forage DMO, at the Estacao Experimental Agronomica • UFRGS • 30°S, from November 1989 to March 1990 (period I) and from October 1990 to May 1991 (period II). Pasture DM production and crude protein were not …
Mineral Supplementation And Phosphorus Fertilizer Application On Native Pastures In North-East Argentina, R M. Pizzio, O Royo Pallares
Mineral Supplementation And Phosphorus Fertilizer Application On Native Pastures In North-East Argentina, R M. Pizzio, O Royo Pallares
IGC Proceedings (1977-2023)
Extensive cattle production systems in north-east Argentina are based on the use of native pastures. One of the most important limiting factors to improve production is the acute phosphorus deficiency of soils and pastures. A large experiment was set up to study the effect of phosphorus fertiliser and mineral supplementation on the liveweight gain of steers of 2 ages grazing native pastures. Supplementation with a mixture of bone meal and salt, residual effect of P fertilisation, and both treatments applied together increased the annual animal live-weight gain by 60, 66 and 106%, respectively. The response of younger steers to fertiliser …

Evaluation Of Panicum Maximum Cultivars Under Grazing, V.P B. Euclides, M.C M. Macedo, A Vieira, M P. Oliveira
IGC Proceedings (1977-2023)
A grazing trial was conducted in Brazil, for a 3-year period, to study animal production from Panicum maximum cultivars (Coloniao, Tobiatii and Tanz5nia-1). Three 1.5-hn paddocks of each cultivar were stocked continuously with 3 steers, and additional grazers were added or removed as required to ensure similar grazing pressure in each treatment. Steers on Tanzania-I had a superior average daily gain (ADG) to those on Tobiatii and Coloniffo. However, the lack of difference in carrying capacity between Tanzdnin and Tobiatil pastures resulted in similar live-weight gain (LWG)/ha. The ADG and LWG/ ha of Coloniilo were significantly lower than the other …

Evaluation Of Brachiaria Decumbens And Brachiaria Brizantha Under Grazing, V.P B. Euclides, A H. Zimmer, M P. Oliveria
IGC Proceedings (1977-2023)
A 3-year grazing trial was conducted in Brazil, to relate changes in sward characteristics of B. decumbens and B. brizantha to animal live-weight gain (LWG). Three 1.5-ha paddocks of each grass species were stocked continuously with 3 steers, and additional grazers were added or removed as required to ensure similar grazing pressure in each treatment. Despite similar (P>0.85) annual average daily gains (ADO) of steers grazing both species, the ADO of steers grazing B. brizantha pasture was significantly (P<0.05) higher during the wet season, and significantly (P<0.05) lower in the dry period, when compared with those on B. decumbens. Annual LWG per area of both species were also similar (P>0.85). The best predictor of ADO was …

Large-Scale Property Demonstrations Of The Effect Of Sexa Stylo And Phosphorus On Beef Cattle Growth In Central Queensland, Australia, C H. Middleton, K J. Murphy, G W. Blight, Vicki-Lee Hansen
IGC Proceedings (1977-2023)
Seca style (Stylosanthes scabra) was oversown into black speargrass (Heteropogon comortus)•dominant pasture after a burn at 2 sites in central Queensland, and the pasture was continuously grazed. At one site with <5 ppm bicarbonate-extractable soil P, Seca growth was poor and gave only a small animal growth response (18 kg/steer/year) over native pasture. With the addition of superphosphate (27 kg P/ha) the Seca-native grass produced an additional live-weight gain of 70 kg/ steer/year over the native pasture control. At a second site with 6-8 ppm available soil P, Seca grew well, and with a P supplement given to steers, live-weight gains were 40 kg/steer/year more than for Psupplemented animals grazing native pasture. Oversowing Seca into native pasture with P as fertiliser or a supplement can dramatically improve animal performance. The project was conducted on private properties and was aimed to focus producer attention on this technology, which is suited to large areas of northern Australia.

Utilization Of Leucaena Leucophala As Fodder For Buffaloes, P C. Gupta, M A. Akbar
IGC Proceedings (1977-2023)
A feeding trial was conducted for 122 days to assess the effect of feeding Leucaena leucophala day on growth rate, utilisation of nutrients, and its toxic effects, if any, in 15 Murrah male buffalo calves about 1 year old. Calves in control group (Tl) were maintained on concentrate mixture and ad lib. wheat straw. The protein of concentrate mixture was replaced at 25% and 50% levels by leucaena protein in the rations of group T2 and T3, respectively, Leucaena hay was isonitrogenous (CP about 19%). The mimosine, tannin and 6-carotene in leucnena hay were 2.50%, 7.33 mg/g and 504.24 mg/kg, …
Increasing Cool-Season Production From Irrigated Leucaena Leucocephala, D Pratchett, S Petty
Increasing Cool-Season Production From Irrigated Leucaena Leucocephala, D Pratchett, S Petty
IGC Proceedings (1977-2023)
Annual live-weight gains of cattle grazing irrigated Leucaena leucocephala in the ORIA (Ord River Irrigation Area) average 0.7 5 kg/day al a stocking rate of 7.5 animals/ha. During the dry season the cooler temperatures reduce the growth rate of leucaena and liveweight gains are reduced lo about 0.5 kg/day. To date growth rates have been maintained by reducing stocking rates but a continuous supply of stock is now required to meet the demands of a local abattoir in the ORIA. During the cooler period a supplement of 1.5 kg maize/animal/day plus hay increased the live-weight gain of cattle to 0.75 …
Grassland Opportunities In The Subtropical Region Of South America, G E. Maraschin, A.V A. Jacques
Grassland Opportunities In The Subtropical Region Of South America, G E. Maraschin, A.V A. Jacques
IGC Proceedings (1977-2023)
Natural grasslands represent a significant proportion of southern South America, which, despite the increase in cropland, is being maintained. However, ignorance and misinformation about the potential of the natural grassland and its environment lead to poor economic results, with live-weight gains (LWG) of around 50-60 kg/ ha/year. Work on the soil-plant-animal relationship have shown that animal performance can be raised to 150-160 kg LWG/ha/year, using sound management practices. The improvement of natural grassland through lime, fertilisation and introduction of exotic species (sodseeding) can further increase production to 500-600 kg LWG/ha/ year. These results illustrate the great potential of natural grasslands …
Planning For A Farming Future, Bruce Milne
Planning For A Farming Future, Bruce Milne
IGC Proceedings (1977-2023)
We have been gathering experience in Whole Farm Planning since our involvement with the Potter Farmland Plan, 1985-1987. Our concerns rose when we reviewed the welfare of the basic finite resources; soil, water, biodiversity and air. We believed those resources were suffering as they supported us, our sheep and cattle enterprises and all other living things, Our concerns caused us to reexamine the purpose of farming. Many farm planners attempt to plan around inherited grazing, economic and trading systems without first questioning the appropriateness of those systems. We attempted to open our minds, remove the existing "fences" and commence farm …

IGC Proceedings (1977-2023)
This paper describe.s some of the spatial variation in microclimate,' soils and vegetation across the black speargrass (Heteropogon contorus) grazing lands of south-east Queensland. Differences in the establishment and survival of oversown legumes, and in animal production', associated with this variation were examined in a largescale grazing trial. The consequences of spatial heterogeneity are discussed in relation to species evaluation, restoration of degraded grazing lands and the development of sustainable grazing systems.
Land Condition And Overgrazing: A Management Paradox For The Savannas Of Northern Australia, Andrew J. Ash, John G. Mcivor, Joel R. Brown
Land Condition And Overgrazing: A Management Paradox For The Savannas Of Northern Australia, Andrew J. Ash, John G. Mcivor, Joel R. Brown
IGC Proceedings (1977-2023)
The tropical savannas of northern Australia have been an important resource for the production of beef for over a century. Excessive stocking rates regimes have led, in some areas, to degradation of the soil and vegetation resource. A state-and-transition model is used to describe the decline in land condition with overgrazing. A grazing study has been established at 2 sites to determine the consequences of a change in land condition for animal production, and pasture production and quality are being related to land condition at additional small sites. Preliminary results indicate that as pasture condition declines, pasture production decreases but …

IGC Proceedings (1977-2023)
A pure Andropogon gayanus sward was compared with a Stylosanthes spp.-A. gayanus mixed sward in order to assess the benefit of introducing N2-fixing legumes on the long-term sustainability of grazed pastures. There was no difference between the total dry matter and animal production of the 2 pastures, although the legumes fixed 67-117 kg/ha of N in 1991 with 80% of the legume N obtained from N2 fixation. Litter deposition was 20-35% greater in the mixed sward and the % N in this litter was also higher, leading to twice the amount of N mineralised in the 0-5 cm …

IGC Proceedings (1977-2023)
Legume-based pastures developed by the Tropical Pastures Program (TPP) of CIAT give spectacular increases in both stocking rates and animal live-weight gains on the savannas of Latin America, A team within the TPP is addressing the problems of their management for legume persistence and soil-plant-animal interactions, using as Its focus a grazing experiment on 2 oxisols of contrasting texture on the Colombian Llanos. The objective is to model the pastures to forecast the effect of management options on long-term persistence and nutrient cycling in grazed legume•grass associations in the Latin American savannas.
