IGC Proceedings (1977-2023)
La prairie de Crau se caracterise par un contexte climatique mediterraneen, un mode d'irrigation par submersion et des facteurs pedologiques particuliers. Destinee principalement a la production de foin, la prairie de Crau n'est generalement paturee qu'a l'automne. Les evolutions, tant dans la conjoncture de l'elevage que dans celle des productions fourrageres, conduisent aujourd'hui a envisager d'accroitre !'utilisation par le paturage, notamment au printemps. Ce sont differents aspects comportementaux de la brebis, importants a prendre en compte pour la gestion de l'herbe, dont nous presentons ici l'etude.

IGC Proceedings (1977-2023)
In chilean arid and semiarid mediterranean ranges with a rainfall of 250 to 600 mm mainly during fall and winter and with a drought period of six to seven months per year natural pasture develops being the main forage source for sheep production. Productivity level is based on a 70-75 lambing percentage and 0.8-0.9 lambs/ewe/year, equivalent to 25-30 kg/ha/yr (at a stocking rate of 1 ewe/ha/yr). The first objective of this research was to quantify the reproductive and productive potential of Precocius Merino ewes, under intensive system with mating every eight months. The second objective was to study the performance …

The Potential Role Of Temperate Pastures For The Production Of Fat Lambs In The Sub Tropics, N M. Tainton, D I. Bransby, M B. Hardy, T M. Du Plessis
IGC Proceedings (1977-2023)
In the sub-humi\i (700-1000 mm rainfall p.a.) sub-tropical regions of Southern Africa, fat lambs have traditionally been produced as a by-product of extensive merino based wool production systems. Natural grassland (veld) or summer growing sub-tropical pastures have formed the basis of the forage system, with dryland winter cereals and root crops often used to supplement the diet. To improve the level of production, a more reliable source of high quality forage needs to be provided to the lactating ewes and to the lambs from birth to slaughter. This need has led to the investigation of possible intensive fat lamb systems …

Animal Production Evaluation Of New Herbage Varieties, J.M M. Munro, D A. Davies
IGC Proceedings (1977-2023)
Although it is now universally accepted that animal performance is the ultimate test of any grassland innovation, few herbage varieties have been evaluated in terms of meat, milk or fibre production. Over the last decade, however, several large grazing trials with beef cattle or sheep have been carried out at Aberystwyth (Munro and Walters, 1986). These have mainly involved promising new Station ryegrass varieties (Lolium spp.) which have completed preliminary screening for yield, persistence and feed quality. In the first trial, comparing two perennial ryegrass (L. perenne) and two cocksfoot (Dactylis glomerata) varieties, steers on Mascot ryegrass …

Forward Rotational Grazing On Digitaria Decumbens Pasture With Weaned Female Creole Goats In Guadeloupe, G Alexandre, H Baudot, P Cruz, S Prache
IGC Proceedings (1977-2023)
Tropical herbage production regulation, obtained through fertilisation and irrigation, doesn't solve the problem of the low nutritive value and the low level of voluntary intake of this herbage. These problems are particulary important with young growing animals regarding to their low ingestive capacity and their high growth requirements. Different pasture management systems have been tested in Guadeloupe (French West Indies) in order to propose a better utilization of tropical pastures.

The Use Of Fertilizer Nitrogen And Increased Animals Production From New Zealand Hill Pastures, D A. Clark, M G. Lambert
IGC Proceedings (1977-2023)
In New Zealand hill pastures, winter and early spring growth is often less than the maintenance of breeding ewes. In late spring and summer, pasture growth often exceeds requirements leading to pasture quality problems. It is usually uneconomic to overcome these problems by conservation, supplementary feeding or adjustement of animal numbers. An increased herbage accumulation in late winter as a result of fertiliser N application, should increase post-lambing ewe liveweights and hence lamb growth rates ; increase ewe mating weights and hence improve flock prolificacy with consequent improvements in the utilisation of summer pasture. Two experiments examined the effect of …

The Performance Of Sucking Lambs Grazing Unfertilized An Fertilized Natural Pasture And Rangeland Under Subarctic Conditions, Olafur Gudmundsson
IGC Proceedings (1977-2023)
Under subartic conditions natural pastures and rangelands are not very productive and are often vulnerable to erosion when overgrazed. The grazing season is also very short, often only four to five months, during which time the lambs have to reach slaughter weight. It is therefore critical to increase carrying capacity and production of the land. Several studies have tested fertilizer use to increase plant production under these condition (e.g., Thorsteinsson and Sigurbjornsson, 1961 ; Arnalds 1974; Arnalds et al. 1980). However, while these studies have shown a manifold increase in forage production and a shift in plant composition to a …

Effect Of Sward Of Perennial Rye-Grass And Red Fescue Type On Gains And Behavior Of Grazing Yearlings, M Rogalski, Z Karzoun
IGC Proceedings (1977-2023)
The output of sheep fed on pasture depends on a number of qualitative and quantitative factors of the sward (Arnold, 1981, Rogalski and Karzoun, 1988). These factors have a decisive influence on the behaviour of animals and the amount of herbage consumed by them and, consequently, on the formation of interrelations between the sward and grazing animals (Rogalski, 1978). The knowledge of these factors is very important if sheep are to be kept in the pasturing systems. Experiments presented in this paper were carried out to determine some of the interdependances and to compare the effect of botanical composition of …

IGC Proceedings (1977-2023)
A proper grazing system is the effective measure to put pasture resources to rational use. Many scholars had compared rotation grazing to continuous grazing. Some results were shown that rotation grazing can bring more herbage production and liveweight gain than the continuous grazing (Allan, 1985), but others were shown that there was no significant difference between rotation and continuous grazing, even the continuous grazing was better than the rotation grazing (Jerry et al, 1987). In the recent years, many scholars had compared the rotation to the continuous grazing in all round way, especially in grassland vegetation and soil characteristics (Heitschmidt …

Better Utilization Of Oversown Tussock Grassland In The Semi-Arid Country Of New Zealand, B E. Allen, J Keoghan
IGC Proceedings (1977-2023)
New'zealand tussock grassland management is traditionally extensive. In the South Island high country the often difficult terrain combined with a harsh and unreliable climate is not inducive to efficient utilisation. Oversowing temperate clovers and grasses and topdressing with sulphur and phosphorus based fertilisers is an accepted way to improve the quantity and quality of pasture, but little is known on how to effectively utilise the extra feed grown. Subdivision fencing is often difficult and expensive and this, together with a lack in clear management objectives, has meant that in many cases inputs into fencing have often not matched inputs into …

IGC Proceedings (1977-2023)
In south-western Australia merino sheep are the primary animal industry. Optimum stocking rates dictate that farmers must budget to hand feed grain to their sheep in late summer/autumn to guarantee their survival and production of a good quality fleece. Income is from wool and sale of surplus animals. The annual production of wool and lambs is largely constrained by the Mediterranean-type climate. Typically the summer drought lasts 3 to 7 months. In summer the dry annual pastures are low in crude protein (around 9 %) and digestibility (around 50 %) and this is associated with a low rate of wool …

Tagasaste (Chamaecytisus palmensis), commonly called 'tree lucerne', is a hardy evergreen leguminous shrub or tree, native to Palma island in the Canary Islands. It was introduced into Australia from the Royal Botanical Gardens, Kew in 1879. In south-western Australia, it has become naturalized along roadsides and at the edges of many native forests. It will grow vigorously from seed on the most infertile deep sands, reaching 3 to 5 m in height and all parts of the stem and branches are enveloped in leaves. In summer, the edible leaf and stem are around 40 % dry matter, 15 …

Studies In Production Of Weaned Merino Lambs In Relation To Pasture Species During Their First Summer In Southern Australia, H Lloyd Davies
IGC Proceedings (1977-2023)
A typical Mediterranean environment imposes problems in ensuring adequate nutrition of weaned lambs during their first summer (Allden 1959). All pasture species will have matured and set seed and generally are of low nutritive value. One solution to this problem is to graze pasture species grown under irrigation. The work reported here is on several investigations into the response of sheep in liveweight and wool production to some pure stands of grasses and legumes.

Effect Of Repeated Applications Of Fluidized Bed Combustion Residue To Reclaimed Surface Mined Pastures, M A. Cochran, J P. Fontenot, H D. Perry, V G. Allen
IGC Proceedings (1977-2023)
Reclaimed surface mined land is potentially valuable for use as pasture, but its low fertility limits its use without soil amendment (Armiger et al., 1976). The usual acidic nature of these soils may result in mineral deficiencies and toxicities in forage (Vogel, 1981). Fluidized bed combustion residue (FBCR) is the residue from combustion of coal with limestone mixed in a jet air stream in coal-burning power plants (Fennelly, 1984). The procedure is used to trap pollutants such as sulfur dioxide, nitrogen oxides, and volatile elements that would normally be emitted into the atmosphere. The FBCR retains about 50 % of …

Galicia is a humid region with mild winters in the atlantic coast of the north west of Spain. White clover and perennial ryegrass perform quite well in the acids soils, after P and lime. application. White clover potential is reduced due to the dry period in July and August. Use of N in spring could compensate this potential despite increasing seasonality. When clover is included in the sward, a low response to N application was expected, as usually happens in small plo1 experiments on an annual basis (Gonzalez, 1982). This experiment attemps to evaluate, in terms of animal production, the …
