The Effect Of Supplementation Of Setaria Grass With Cassava Or Gliricidia Leaves On Growing Sheep, S S. Sitorus
IGC Proceedings (1977-2023)
In tropical areas, grasses are the main forage offered to ruminant, eventhough they have low quality such as native grass crude protein of about 7-12 %, and napier grass about 9-14 %. Recently in Indonesia, plantation of setaria grass was introduced especially in transmigration and watershed areas, regardless its nutritive value, and its influence on animal performances. Similar with other grasses, setaria grass has a low nutritive value and when fed alone can not meet the production requirements. More over, Jones et al. (1970) reported that cattle with setaria in a grazing system can lead to the death due to …

La culture de la luzerne (Medicago sativa L.) dans le Nord Ouest du Maroc se heurte a de nombreuses difficultes parmi lesquelles les conditions pedoclimatiques defavorables a son implantation. C'est la raison pour laquelle les systemes fourragers de cette region reposent essentiellement sur !'utilisation en vert du bersim (Trifolium alexandrinum L.) pendant l'hiver et le printemps. Cependant, la tres forte teneur en eau de cette plante la rend tres difficile a conserver, ce qui pose des problemes de calendrier alimentaire pour les troupeaux laitiers pendant l'ete et le debut d'automne. De ce fait, !'introduction du Ray-grass d'Italie (RGI) a …

Proportion Of Leaves And Floral Tillers And Nutritional Quality Of Prolific And Non-Prolific Seed Yielding Cultivars Of Smooth Bromegrass, S Bittman, Z Mir, D H. Mccartney
IGC Proceedings (1977-2023)
In the semi-arid clima\e of the Canadian Prairies most herbage production occurs in May and June whereas the grazing season lasts until October. Summer and fall pasture consists largely of mature, quiescent vegetation with senescent leaves and lignified stems. Floral tillers of some temperate grasses have a higher rate of leaf senescence than non-floral tillers (Bittman et al., 1988) and are rejected by grazing cattle. Floral tillers of Stipa viridula Trin. and Pascopyrum sinithii (Rydb.) Love had 2 and 4 % units lower protein content and digestibility, respectively, than non-floral tillers (White, 1983). In the Parkland region of the prairies, …

Nutritive Value And Production Of Cool-Season Under Two Harvest Regimes, T Kunelius
IGC Proceedings (1977-2023)
In Atlantic Canada, Phleum pratense L. is the predominant grass species grown for conserved feed and pasture. Although P. pratense is a persistent grass species under 2 cut systems (Kunelius and McRae, 1986) it does not perform adequately under intensive management. Secondary grasses for the Atlantic region include Dactylis glomerata L., Festuca pratensis L., Bromus inermis Leyss., and Lolium-Festuca hybrids. There is considerable interest in the performance and quality of secondary grasses and those of Lolium-Festuca hybrids in particular, under various management regimes. In this experiment the growth and quality of several cool season grasses were determined under four and …
Change In Composition And Quality Of A Temperate Species Mixed Pasture Grazed Over Three Years At Two Stocking Rates With And Without Nitrogen Fertilizer, K Betteridge, D A. Haynes, J R. Sedcole
IGC Proceedings (1977-2023)
Animal production is not only affected by pasture mass and its seasonal distribution but also by the composition and quality of the consumed pasture (Rattray and Clark, 1984). Legumes have a higher nutritive value than grasses, but may be suppressed by application of artificial nitrogen (N) when soil N status is low (Ball and Field, 1982). Nutritive value of pasture falls as it matures due to a rise in fibrous tissue and a decline in digestibility, and mineral and protein content (Ulyatt, 1978). However, vegetative growth can be prolonged and quality maintained by greater utilisation of pasture in late spring …

Smooth Brome Response To Rate And Date Of Mefluidide Application, B Anderson, R S. Moomaw, C A. Shapiro
IGC Proceedings (1977-2023)
Smooth brome (Bromus inermis Leyss.) often produces over 70 % of its annual growth during spring. Summer growth and forage quality are poor. Mefluidide suppresses seedstalk production and improves forage quality of many cool-season grasses (Sheaffer and Marten, 1986). This study evaluated the response of smooth brome to date and rate of mefluidide application.

Evaluating Forage Quality As Animal Production Per Unit Of Forage And Land Area, D A. Rohweder, L Miller
IGC Proceedings (1977-2023)
The need to more adequately express feed value in forages and, that will communicate this value among agricultural scientists, agri-business clientele and producers has long been recognized world wide. Modern dairy, beef and sheep producers are becoming increasingly concerned about forage quality ; its translation into animal products per unit land area ; and its effect along with forage yield on enterprise profits. The Hay Marketing Task Force-Forage Analysis Subcommittee organized by the American Forage and Grassland Council in 1975 proposed hay standards based on in vivo digestible dry matter or energy availability (DDM) and dry matter intake (DMI) predicated …

Adaptation And Forage Quality Of Grasses Grown Under Shade, K D. Kephart, D R. Buxton
IGC Proceedings (1977-2023)
The three fundamental environmental factors which influence plant growth are water, temperature, and light. Light may be separated into photoperiod - and irradiance - related factors. Grasses adapt to reduced irradiance regimes by increasing leaf area and stem length and by decreasing leaf thickness and plant dry weight. Leaf thickness in grasses is altered by changes in cell size (Cooper and Tainton, 1968). These morphological and anatomical adjustments to irradiance regime may affect cell-wall concentration and forage quality. Adaptation to reduced irradiance has resulted in lower soluble carbohydrate concentration and increased total-nitrogen concentration (Deinum and Dirven, 1972; Wong and Wilson, …

Differences In Nutritive Value Of Lecerne Cut In Morning And Afternoon Hours, F Plhak
IGC Proceedings (1977-2023)
Beside crude fibre and protein, the photosynthetic products - nonstructural carbohydrates - are further important substances of digestible dry matter in lucerne fodder. They participate in dry matter by 15 %. In contrast to crude fibre and protein, the content of photosynthates changes expressively during the day (Plhak, 1984). The changes reach in leaves by 20 %, in stems 5 % of dry matter. The changes depend on the length and intensity ofsolar irradiance (Plhak, 1981) and cause specific weight alteration of leaves (Chatterton et al., 1972). Such variations in photosynthates content can cause some changes in dry matter digestibility …
Productivity And Nutritive Values In Three Ecotypes Of Trichloris Crinita, Native Forage Grass Of The Arid Zones Of Argentina, J Silva Colomer, J B. Cavagnaro, J Lemes, M Medero
IGC Proceedings (1977-2023)
Livestock activity in the arid and semiarid regions of the west central part of Argentina is mainly based on native grasses. On the plain areas of Mendoza province, the most important grasses are perennial, warm-season species, adapted to water stress, high temperature and high irradiance conditions (Cavagnaro, 1988). Mean rainfall of the area reached at 264 mm during the growing season. Trichloris crinita is one of the outstanding species in many areas of the mentioned region. In order to preserve genetic variability of natural populations, IADIZA (Instituto Argentino de Investigacion de Zonas Aridas) initiated a germplasm bank of native forage …

Evaluating Maturity And Preservation Method Of Alfalfa On Optimum Rations For Lactating Dairy Cattle Based Upon Neutral Detergent Fiber Concentration Of The Total Diet, R W. Hintz, D R. Mertens, K A. Albrecht
IGC Proceedings (1977-2023)
Previous research has shown that formulating rations based upon neutral detergent fiber (NDF) concentration of the total diet can be an effective means of maximizing the performance of lactating dairy cattle (Mertens, 1982). Results of these studies indicated that ration formulation using NDF is a robust procedure, but that differences in the optimum NDF level may exist between forages conserved in different manners. To determine if the method of forage preservation affects the optimum NDF concentration of diets, a study was designed to compare the response of lactating dairy cattle to diets of identical NDF concentration formulated using third-crop alfalfa …

Animal Performance As Effected By Herbage Availability And Quality In Semi-Arid Southern African Grassland, J E. Danckwerts
IGC Proceedings (1977-2023)
Rotational grazing with beef cattle is widely advocated and practised under commercial pastoralism in semi-arid grassland in southern Africa. Since animal performance is largely a function of the quality and quantity of forage ingested, changes in herbage quality and availability in these situations are likely to have an important influence on animal production. The objective of this paper is therefore to quantify changes in the quality of herbage ingested by beef cattle at different times of the year and as grazing pressure increases within periods of occupation on rotationally grazed semi-arid grassland in southern Africa. The effect of these changes …

The Intake And Digestibility Of Dry Mature Subterranean Clovers, G B. Taylor, R C. Rossiter, D B. Purser, W J. Collins
IGC Proceedings (1977-2023)
Although sheep grazing dry subterranean clover (Trifolium subterraneum L.) pasture may maintain body weight for the early part of summer, they usually lose weight during late summer and autumn, with consequent adverse effects on productivity (Purser, 1980). A decline in the digestibility of clover during plant senescence (Hume and Purser, 1975) is believed to be an important component of the reduced nutritive value of this dry feed. In a survey of dry mature stem material from a range of early flowering subterranean clover genotypes, Taylor et al. (1987a) found that in vitro digestibility ranged between 41 and 62 % …

Forage Production And Nutritive Value Of Cynodon Spp. Under Grazing In Puerto Rico, L E. Tergas, Y Q. Cabrera, A Sotomayor Rios
IGC Proceedings (1977-2023)
Livestock production in the tropics is highly dependent on forages to meet the nutritional requirements of grazing cattle. However, seasonal fluctuations on dry matter production and nutritive value are limiting factors affecting animal performance and production. Stargrass Cynodon nlemfuensis var. nlemfuensis is a highly productive grass recommended for intensive management in the humid tropics of Puerto Rico (Vicente-Chandler et al., 1974). Bermuda Cynodon dactylon and Stargrass produced high yields of quality forage and persisted under intensive grazing in the humid northern coastal plains of Puerto Rico; however, the average production of both grasses was related to rainfall distribution, decreasing during …

Prediction Of The Yield Of Nutritive Matter In Some Autumn Cut Forage Catchcrops, K Kastelic, J A. Nikolic, A Pavlicevic, T Stupica, J Cizec
IGC Proceedings (1977-2023)
Arable land often lies fallow for a time, which provides an opportunity for growing fodder catchcrops between two main crops. This practice should improve the soil structure, conserve soil moisture, eliminate many weeds, maximise land use and enable easier preparation for the subsequent main crop. Moreover, subsequent cereal yields may be increased by preceding forage legume crops (Papastylianou and Samios, 1987). The aim of present investigation was to determine the concentration of promising autumn cut catchcrops (D-value) and to assess the possibility of predicting the yield of digestible organic matter (DOM) from the yield of green or dry matter (DM).

Changes In Digestibility With Regrowth Of Some Temperate Grasses, K Watanabe, S Furukawa, A Sato, S Saiga
IGC Proceedings (1977-2023)
Many workers have reported that the decline in digestibility of temperate grasses were steep after heading in 1st cut and lenient during the regrowth in 2nd and 3rd cuts. But in some grasses, heading is observed even in 2nd and 3rd cuts, and the late stages of regrowth were sometimes accompanied by high temperature which usually accelerate the decline in digestibility. So even in the regrowth, digestibility is one of the important factors to optimize cutting stage of grasses. Cutting stages in the regrowth of grasses have been discussed from the standpoint of dry matter production (Watanabe et al., 1984; …

Feeding Behavior Of Bali Cattle Fed Gliricidia Diet, K Lana, I M. Nitis, S Putra, M Suarna, W Sukanten
IGC Proceedings (1977-2023)
Even though Gliricidia sepium has been used as fodder in the tropics, the extend of its utilization by ruminant is not well documented (NFTA, 1987). When mixed with other forages, Gliricidia sepium consumption by Bali cattle can be as high as 50 % during the wet season and increases up to 66 % during the dry season (Nitis et al., 1988). The presence of inhibiting substances has been suggested to cause the low palatibility of the Gliricidia leaf (Cheeke and Raharjo, 1987; Rodriguez et al., 1987). The objective of this experiment was to study the preference of Bali steer on …

Electronic Measurement Of Grazing Time And Intake In Free Roaming Livestock, J R. Forwood, M M. Hulse
IGC Proceedings (1977-2023)
Herbage intake is one of the critical factors in understanding why livestock perform at various levels on different forages, however acceptable methods of measuring voluntary intake of free-roaming livestock are still lacking. Commonly used indirect measurement methods estimate pasture herbage loss or animal gain, fecal output and digestibility equations, grazing behavior calculations or indicators (Greenlaugh, 1982). More direct attempts of measuring intake include the Animal Weight Telemetry System (AWATS) of Horn and Miller (1979), multiple impedance plethysmography (Stuth et al., 1981) and the conductivity transducing cannula (CTC: Forwood et al., 1985). With new technology becoming available in smaller, more affordable …

Pasture Species Preferences By Horses In New Zealand, W F. Hunt, R.J M. Hay, D Clark
IGC Proceedings (1977-2023)
The equine breeding industry of New Zealand makes a considerable contribution to the export earnings, but the production base of that industry, i.e. the equine pastures have been neglected by our researchers. Thoroughbred studs are established on ex-dairy or ex-sheep farms which are usually sown with perennial ryegrass and white clover. Ryegrass based pastures can be highly productive, but in New Zealand suffer from the Argentine stem weevil - ryegrass staggers dilemma. i.e. Low endophyte ryegrasses do not survive Argentine stem weevil, but resistant high-endophyte ryegrasses cause the animal muscular disorder« ryegrass staggers». The seasonal productivity pattern of ryegrass is …
