Chemical And Nutritive Values Of Three Ensiled Residues (Broad Beans, Peas And Soybean) In Comparison With Yellow Lupin Silage, J Efe Serrano Jun 2025

Chemical And Nutritive Values Of Three Ensiled Residues (Broad Beans, Peas And Soybean) In Comparison With Yellow Lupin Silage, J Efe Serrano

IGC Proceedings (1977-2023)

The agro-industrial residues of legumes in Portugal has increased recently in animal feeding, but with little information about the nutritive values of these diets. The few values from literature (Economides and Had­jidemetriou, 1974; Boza and Guerreiro, 1981 ; Escandon et al., 1983) or in Tables of Food Composition are quite different. In south of Portugal, the yellow lupin is an expanding forage used in sheep diets as hay or silage. The purpose of this work, and others in progress, was to compare the feeding value of silages made from three important residues with the yellow lupin silage.

Effects Of Wilting And Formic Acid On The Chemical Composition And Nutritive Value Of Elephant Grass Silage Pennisetum Purpureum Schum) Purple Cultivar, W Lavezzo, Otavia E.N.M Lavezzo, C Rossi, I A. Bonassi

IGC Proceedings (1977-2023)

At the beginning of the growth the Elephant grass had a good dry matter production and a good nutritive value and due to this it is often used for ensilage in Brazil. However, when best suited age for ensilage (50-60 days), its water content is high making normally difficult to get suitable silages. Although reasonable silages of Elephant grass have been obtained with no additives (Tosi et al., 1983), the wilting and formic acid utili­zation during the ensilage have resulted in good quality silages (Silveira et al., 1979) with good nutritive value (Lavezzo et al., 1984). The purpose of this …

Corn Crop Grown With And Without Tropical Legumes For Silage Making, J A. Obeid, M E. Cruz Jun 2025

Corn Crop Grown With And Without Tropical Legumes For Silage Making, J A. Obeid, M E. Cruz

IGC Proceedings (1977-2023)

Under Brasilian conditions the beef and milk production rely almost exclusively upon the use of natural or cultivated pastures. However, due to the characteristics of the climate with a warm and rainy season and a cool and dry season, the forage growth rate and animal production presents both high and low peaks, resulting in slaughtering age of 4-5 years and a low average milk production (Pedreira, 1973). Improvement of forage production has been one approach for increasing animal production. However, the above measure brings a higher attention to the feeding of the animals in the dry season. Most often, use …

Changes In The Chemical Composition Of Wheat For Silage During Development In A Warm Climate, G Ashbell, Z G. Weinberg Jun 2025

Changes In The Chemical Composition Of Wheat For Silage During Development In A Warm Climate, G Ashbell, Z G. Weinberg

IGC Proceedings (1977-2023)

Wheat for silage in Israel is usually grown as a winter crop in a double-cropping system. In such a system, the wheat is harvested before it reaches maturity and the land is then ready for the summer crop. The periods between the various matu­ration stages of wheat are relatively short, especially in a warm climate. Ash bell (1984) and Ashbell et al. (1985) found that the greatest changes in nutritive components of the whole wheat plant occurred between the flowering and the milk ripening stages. During that period there is an increase in dry matter (DM) and water soluble carbohydrates …

Fire Effects On Herbage Yield And Nutritive Value Of Natural Grasslands In Uganda, E N. Sabiiti, R W. Wein Jun 2025

Fire Effects On Herbage Yield And Nutritive Value Of Natural Grasslands In Uganda, E N. Sabiiti, R W. Wein

IGC Proceedings (1977-2023)

Fire has long influenced the development, maintenance and productivity of nearly 80% of the Uganda natural grasslands which are important for livestock grazing. However, tra­ditional burning appears to reduce the productivity of these natural pastures, especially in the Acacia/savanna grassland since there is no proper fire regime (fire intensity, severity and frequency) used by these pastoralists/as there is limited research that gives reliable data on how to use prescribed fires on these pastures lands (Sabiiti et al., 1986; Sabiiti and Wein, 1987; Harrington, 1974). Consequently, most of these pastures have been invaded by coarse and less nutritive grass species …

Variability Of A Tropical Savannah And Its Influence On Management Practices And Animal Weight Gains, R R. Vera, B Rivera, J H. Weniger Jun 2025

Variability Of A Tropical Savannah And Its Influence On Management Practices And Animal Weight Gains, R R. Vera, B Rivera, J H. Weniger

IGC Proceedings (1977-2023)

The savannah of the Colombian and Venezuelan plains have been relatively well studied from a floristic point of view and several major plant communities are recognized (Blydenstein, 1967). Nevertheless, the potential contribution of these plant communities to ruminant production have not been studied, except for the largest of these associations, that of the well­drained high savannah. Paladines and Leal (1979) have shown that it has low carrying capacity and sustains low levels of ani­mal production both per head and per animal, despite moder­ate levels of primary productivity. In effect, animal weight gains range from 70-90 kg head-1 and 18-40 kg …

Yield And Quality Of Signal Grass Stockpiled At Different Dates, E A. Pizzaro, R R. Vera

IGC Proceedings (1977-2023)

The savannas of the 'Cerrado' region of Brazil extend over 20 % of the brazilian territory, supporting over 50 % of the beef cattle industry (Kornelius et al., 1979). During the long dry season there is a pronounced deficit of quality in the natural savannas; conserved and standing crops (Pizarro and Vera, 1980; Paiva et al., 1978; Vera et al., 1981) pure legumes stands have been tested successfully to supplement the native veg­etation (Tergas et al., 1983). Large leafy yields have been reported during the second half of the dry season (Vera et al., 1981 ; Pizarro et al., 1985). …

Distributions Of Yields And Nutritional Value In Native Pastures In South China, Zhiqiang Lai Jun 2025

Distributions Of Yields And Nutritional Value In Native Pastures In South China, Zhiqiang Lai

IGC Proceedings (1977-2023)

There are about 40 millions ha of gqtzeable hill tussocky pastures in south China, generally with an elevation below 500 m and slopes between 6 to 30°. They are suited to ruminant animal husbandry with good rainfall, long growth period and a variety of high yielding plants. But most of the swards are improperly used and managed. This damages the pasture resources, and causes erosion due to overgrazing resulting in ecological unbalances and eventually, hazards the development of ruminant husbandry. The aim of this trial was, by studying the growth rhythm, seasonal distributions of the yield and nutritional value of …

Year Round Protein Of Native Grasses Of Lesotho, C J. Goebel, G Seutloal, V Ramakhula Jun 2025

Year Round Protein Of Native Grasses Of Lesotho, C J. Goebel, G Seutloal, V Ramakhula

IGC Proceedings (1977-2023)

Rangelands of Lesotho are primarily located in the "sour veld " region of southern Africa. Percentagewise, the lands are cxtc11sive and furnish large quantities of forage for various type, of grazing animals. Detailed information upon nutritive qua I I ty of the native grasses would be of major benefit to assist in planning rotation grazing programs during critical periods or the year. In addition, there is a need for information of the nutrttional quality of introduced grasses to Lesotho's rangelands.

Dorycnium And Other Mediterranean Species - Their Use For Forage And Soil Conservation In Semi-Arid Environments Of New Zealand, B J. Wills, J.S C. Begg, J S.S Sheppard Jun 2025

Dorycnium And Other Mediterranean Species - Their Use For Forage And Soil Conservation In Semi-Arid Environments Of New Zealand, B J. Wills, J.S C. Begg, J S.S Sheppard

IGC Proceedings (1977-2023)

Dorycnium is one of several Mediterranean plant species that have been under evaluation for soil conservation purposes in New Zealand since the 1970's. In the dry South Island hill country, particular problems exist in relation to drought-prone, wind and frost affected, low to moderate fertility soils. In many cases these areas can provide for stock wintering and lambing, but in a semi-arid climate they produce little stock forage and provide an ideal habitat for rabbits. The two Dorycnium species described in this paper are nitro­gen fixing, leguminous plants which have shown considerable promise for revegetation in drought-prone and semi-arid areas …

Salt Tolerant Legumes From The Guadalquivir Delta (S.W. Spain), T Maranon, J M. Romero, J M. Murillo Jun 2025

Salt Tolerant Legumes From The Guadalquivir Delta (S.W. Spain), T Maranon, J M. Romero, J M. Murillo

IGC Proceedings (1977-2023)

Saline environments occupy about 15 millions ha in the Mediterranean basin (Le Houerou, 1986). Many of those areas have been traditionally devoted to grazing. Native salt tolerant ecotypes of forage legumes and grasses are increasingly menaced. Overgrazing may lead to local extinction of the most palatable races ; on the other hand, their habitats are decreasing in salt marshes by drainage and farm­land reclamation. Therefore, a coordinated program of survey, evaluation and conservation of salt tolerant plant genetic resources would be desirable in the Mediterranean basin. A project to study the ecology, physiology and nutritive value of salt tolerant annual …

Improving Pasture Resources In West Africa: Evaluation Of Forage Legumes To Meet The Social And Ecological Constraints, S A. Tarawali, M Peters, M A. Mohamed Saleem Jun 2025

Improving Pasture Resources In West Africa: Evaluation Of Forage Legumes To Meet The Social And Ecological Constraints, S A. Tarawali, M Peters, M A. Mohamed Saleem

IGC Proceedings (1977-2023)

Throughout sub-Saharan Africa, poor nutrition is a major constraint to livestock production (Henzell and t'Mannetje, 1980). In the West African subhumid and semi arid zones, the harsh dry season means that the quality of the naturally avail­able forage is insufficient to meet cattle maintenance requirements for more than half the year (Mohamed-Saleem, 1986) ; in more humid areas intensive cropping restricts access to fodder. The introduction of improved forage legumes is recognised to be a viable approach to alleviating this problem (Jones et al., 1984). In Nigeria, the International Livestock Centre for Africa (ILCA) has successfully introduced Stylosan­thes pastures to …

Structure And Function Of The Central Himalayan Alpine Grassland, India, J Ram, S P. Singh Jun 2025

Structure And Function Of The Central Himalayan Alpine Grassland, India, J Ram, S P. Singh

IGC Proceedings (1977-2023)

Extensive alpine and sub-alpine pastures occur in Central Himalaya (28-31° N lat. and 79-81° E long.) at 3.000-4.500 rn. There is a notable lack of quantitative information on high mountain grasslands in India. During the snow-free surnrner period (May to September), graziers both from plains and hills stay in these meadows to graze their sheep, horses and cattle. The primary objective of this study was to quantify the struc­ture and productivity of Himalayan alpine grassland and com­pare the same with alpine sites distributed elsewhere and those of the adjacent Gangetic plains.

Interest Of Traditional Practices To Improve Grassland Fertility In The Central Pyrenees, G Balent, M Duru Jun 2025

Interest Of Traditional Practices To Improve Grassland Fertility In The Central Pyrenees, G Balent, M Duru

IGC Proceedings (1977-2023)

In the Central Pyrenees, the decline of agriculture has led to the transformation of fields into grasslands. The study of the dynamic of this secundary succession has shown the import­ance of residual soil fertility and grazing pressure on the botan­ical composition of plots (Balent & Duru, 1984). The actuals trends of evolution consist in a general decrease of soil fertility and, an irregular distribution of grazing pressure, the free-ran­ging animals selecting, during winter and early spring, the sites of higher fertility (Balent, 1986). From the mineral and botanical compositions of the veg­etation, we examine the interest of three traditional manage­ment …

Importance Of Productive Grasslands In Protected Landscape Regions, Holecy Bohus Jun 2025

Importance Of Productive Grasslands In Protected Landscape Regions, Holecy Bohus

IGC Proceedings (1977-2023)

Grasslands, especially pastures, are often situated on extreme mountain sites in our country. Due to their botanical structure and natural production potential, they influence the ecological character of the region and give the impression of protected landscape. The aim is to preserve this specific character of the lanscape and on the other hand to look for the moderate grassland improvement and better utilization by nutrition and regular grazing. The untreated and non-utilized grasslands can lead to unfavourable changes of swards in the high localities. Therefore we tried to solve the moderate improvement of natural subalpine grasslands in the High Tatra …

Sociabilities, Morphologie Et Valeurs Nutritives Des Vegetations Prairiales, J M. Dorioz, Ph Fleury, B Jeannin

IGC Proceedings (1977-2023)

Les especes dominantes des prairies presentent souvent une grande plasticite phenotypique dont les manifestations les plus spectaculaires au plan fourrager sont les changements du port, du volume relatif des organes et de la phenologie (Hedin, 1945; Hayne, 1983). L'amplitude de ces variations dans une meme region est mal connue. On peut done se demander dans quelle mesure elles remettent en cause la valeur indicatrice habituelle­ment attribuee a ce type d'especes, en outre, s'il n'est pas utile de chercher a codifier la morphologie des dominantes, pour ameliorer les diagnostics agronomiques.

Planning Seasonal Forage Strategies In Dairy Farms A Linear Programming Approach, G Pichard, J Ortega, R Cussen Jun 2025

Planning Seasonal Forage Strategies In Dairy Farms A Linear Programming Approach, G Pichard, J Ortega, R Cussen

IGC Proceedings (1977-2023)

The nutritional requirement of any dairy herd varies along the year according mainly with the liveweight and the physio­logical stages of the animals. Similarily the grasslands and for­age crops have specific and characteristic seasonal behaviour, both in terms of growth rate and nutritional quality. This situ­ation is very dynamic and may become difficult to handle when several alternatives of forage species have to be combined in order to meet the animal requirements. In the humid temperate regions in Chile, most of the forage production in permanent grasslands occurs in spring because of the extreme drought during summer and low temperature-high …

Comparison Of Meat Performance Of Lambs Kept On Pastures And Intensively Fed On Pastures As Well As In Fattening Units, S Kukovics, T Schuszter, Cs Lanyi Jun 2025

Comparison Of Meat Performance Of Lambs Kept On Pastures And Intensively Fed On Pastures As Well As In Fattening Units, S Kukovics, T Schuszter, Cs Lanyi

IGC Proceedings (1977-2023)

Hungary is an exporting country in lambs which go for export either live or slaughtered. The majority of lambs are intensively fattened before slaughter or before live export. In the fattening pens (group fatting), a mixture of pelleted feed is offered ad libitum, but, in many cases, hay and/or straw are also fed. This feeding technology involves significant costs ; therefore, the testing of various fattening methods have been aimed at. Besides, we wished to study the fattening performance of imported Corriedale and Romney sheep, by using New-Zeal­and as well as Hungarian methods.

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 Performance Of Sucking Lambs Grazing Unfertilized An Fertilized Natural Pasture And Rangeland Under Subarctic Conditions, Olafur Gudmundsson Jun 2025

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 …

Studies In Production Of Weaned Merino Lambs In Relation To Pasture Species During Their First Summer In Southern Australia, H Lloyd Davies Jun 2025

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.

The Effects Of Graminaceous Species And Stocking Rate On Grazing Performance Of Charolais Steers, Francoise Riviere, Odile Colin Jun 2025

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.

Evaluation Of Three Tropical Perennial Grasses For Beef Production In South Central Florida, A Larbi, P Mislevy, W F. Brown, M B. Adjei

IGC Proceedings (1977-2023)

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 …

Efficiency Of Grazing On Growth And Nutrient Intake Of Dairy Heifers, M Okamoto, I Iketaki, N Hasegawa, N Yoshida

IGC Proceedings (1977-2023)

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 …

IGC Proceedings (1977-2023)

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 …
