The Effects Of Graminaceous Species And Stocking Rate On Grazing Performance Of Charolais Steers, Francoise Riviere, Odile Colin
IGC Proceedings (1977-2023)
High daily intakes of herbage with high digestibility are required to maximise animal production output per hectare from grazing. Tall fescue (TF) is well known for its high herbage production but its nutritive value may limit animal growth (Jacobson, 1969). Recently progress in sward species selection has provided· new TF cultivars with smooth leaves more digestible and better ingested by animals than the previous cultivars. The purpose of the trials reported here was to study, in comparison with perennial rye grass (PRG), the influence of new tall fescue cultivars, on steers growth grazing at two stocking rates.

In the North Massif Central lowlands of France the grazing management of the Charolais herd on permanent pasture is usually based on free grazing and low levels of nitrogen fertilizer resulting in low stocking rates i.e. 0,8 to 1,0 cow and calf per hectare. Some authors in France have reported results of grazing beef cows in areas with adequat rainfall in summer (Petit and Muller, 1980; Leblanc et al., 1983) but there is little information on the response to intensification from herds kept under drought conditions in summer. Four experiments were conducted at Jeu-les-Bois (Indre) in successive years 1978-1981 to …

Fishmeal, Cottonseed Meal, And Corn Supplements With Rumensin For Stockers Grazing Hybrid Sorghum X Sudangrass Pastures, D Hutcheson, J Mcneill, M Rouguette, B Ellis
IGC Proceedings (1977-2023)
Cattle grazing hybrid sorghum x sudangrass pastures during the summer usually gain only 60-7 5 % of their projected gain. The specific cause for this lack of gain is not known. Hybrid sorghum x sudangrass forages are considered adequate in nitrogen for stocker cattle. However, a portion of that nitrogen may be in the form of non-protein nitrogen ; thus, these forages may actually be protein deficient for stocker cattle. Fishmeal appears to be an effective source of escape or by-pass supplementary protein for the ruminant. Cottonseed meal is a typical oil seed meal and is readily available for incorporation …

Species of the genus Cynodon (Bermudagrasses and stargrasses) have a considerable potential for grazing in southern Florida (Adjei et al., 1980, Pitman et al., 1984). Preliminary evaluation studies indicate that two new stargrass cultivars, Florico and Florona ( Cynodon nlemfuensis Vanderyst var nlemfuensis) and Callie Hybrid Bermudagrass [C. dactylon (L.) Pers Tifton 44 X Callie], may offer alternatives to commercially available cultivars, due to their high forage production, persistence, cold tolerance and better nutritive value (Mislevy et al., 1981 and Brown, 1986). Little is known, however, of animal performance on these grasses under grazing. The objective of the study was …

Les plateaux herbagers du Nord du Massif Central (France) sont d'altitude moyenne (ll00 m) et beneficient d'un climat oceanique montagnard, permettant une saison de paturage de 5-6 mois. Les prairies naturelles a base de graminees fournissent une herbe abondante au printemps, mais leur production estivale peut etre fortement limitee par la pluviometrie. Ces prairies sont utilisees par des troupeaux de vaches allaitantes, sous-alimentees pendant l'hiver, qui doivent reconstituer leurs reserves corporelles au paturage. La croissance au paturage des veaux, allaites par leurs meres, depend de la qualite et de la quantite d'herbe disponible (Petit et Muller, 1980; Leblanc et al, …

Grazing has traditionally been recognized as one of the most important labor-saving means in which herbage can be utilized more economically. However, in Japan, the practice of grazing is declining due to improved farm management - more animals per farm, greater harvest yield per area and higher production performance. Grazing animals tend to be healthier and more productive than animals kept in confinement. In addition, feed cost of raising dairy heifers on high pasture system is reduced by more than 50 % relative to the conventional (dry lot) system and to 65 % when the cost oflabor and facilities are …

Digitaria eriantha subsp. eriantha, previously known as D. smutsii (Russel and Smook 1980), is a robust perennial grass adapted to a wide range of soils and climatic conditions. In Australia, the species has performed well on a number of sites with soils ranging from« cracking clays to sandy loams» where rainfall varied between 400 and 1000 mm/annum (Strickland 1987). A similar range of adaptability has been recorded in South Africa (Brockett and Gray 1984, Dannhauser 1985). In cutting trials, D. eriantha yielded between 3500 and 15000 kg of dry matter/ha with annual rainfall of 450 and 1200 mm/annum respectively. The …

Beef production in Brazil is based on the high dry-matter production of tropical grasses, but yields are not always satisfactory. Nitrogen fertilization results in linear increases of drymatter production (Gomide et al., 1984) and also in the liveweight-gain (LWG) of the animals (Addison et al., 1985). However, due to the high cost of fertilizers, the utilization of grass pastures associated to herbaceous or shrub legumes may be an economic way to increase animal production. The aim of this work was to study the availability of dry-matter and the L WG of steers in Guineagrass (Panicum maximum Jacq.) pastures fertilized with …

In grassland based systems of animal production, it is important to choose a genotype of animal with production characteristics appropriate to the level of nutrition which can be supplied by the available resources. It is generally recognised that the most economically efficient beef cow systems are those that allow the cows to increase levels of body fat when feed is plentiful or cheap (eg. summer grazing in N. Europe) and to draw on those reserves during periods of feed scarcity or when feed is expensive (eg. winter) (Russel and Broadbent, 1985). The ability of cows to increase body reserves during …

Preweaning growth of beef calves is determined by milk production of the dam and herbage consumption by the calf. These parameters are impacted by quantity of herbage on offer and nutritive quality of the sward. Forage availability and quality are dependent upon species composition and pasture management. In the humid temperate regions, both C3 and C4 species are utilized in grazing programs with traditional grazing management being either continuous or very lax rotations. A grazing study was undertaken to evaluate the preweaning growth of calves and milk production of their dams as impacted by pasture species and intensity of management …

Throughout much of the world cattle are produced mainly on forage. High grain yields in the U.S. have led to feeding cattle high grain to minimize time in the feedlot, and overhead costs. Recent emphasis on lean meat, diet and health issues has renewed interest in finishing cattle on forages. The objective of this research was to evaluate various forage systems of beef production from conception through slaughter with minimum grain. Effects of forage system during cow-calf and growing phases on performance and carcass characteristics during the finishing phases were evaluated. The research included calves born in late winter-early spring …

Milk production levels achieved by dairy cows, and the growth rates of newly weaned calves, grazing ryegrass/white clover pastures during autumn in New Zealand are normally lower than those achieved during spring (Wilson, 1988), The present experiment was undertaken to compare the effects of milk replacers and concentrate supplementation on the grass intakes and performance of 6-11 week-old calves. A second objective was to investigate if the form in which milk replacer was fed (liquid or powder) influenced the responses. Such information is required to provide reasons for the poor performance of cattle in the autumn and also to demonstrate …

Tall fescue (Festuca arundinacea Schreb.) is the predominant forage available to beef cattle producers in the transition zone of the eastern US. The presence of the endophytic fungus Acremonium coenophialum Morgan-Jone & Garns has been associated with reduced animal performance that results in substantial economic loss to producers (Bacon and Siegel, 1988; Bush and Burrus, 1988; Stuedemann and Hoveland, 1988). Cattle producers have used N fertilization to increase productivity of fescue pastures. Renovation of fescue pastures with legumes has been a method of improving pasture quality and the performance of animals grazing those pasture (McLaren et al., 1983).

Two-thirds of the grazing lands in Queensland are on infertile soils, low in organic matter, phosphorus (P) and nitrogen (N) (Weston et al., 1981). Pasture quality is low and average liveweight gain (L WG) of steers on these soils ranges from 0.10 to 0.30 kg/day compared to 0.40 to 0.50 kg/day on more fertile soils. Low herbage production limits carrying capacity to 3-10 ha/animal. The nutritive value can be improved by (i) direct supplementation of animals with N and P, (ii) introduction of a legume together with fertilizer and/or supplement P or (iii) use of heavily fertilized improved grasses ± …
