Aeschynomene And Carpon Desmodium: Legumes For Bahiagrass Pasture In Florida, Lynn E. Sollenberger, R. S. Kalmbacher Jun 2023

Aeschynomene And Carpon Desmodium: Legumes For Bahiagrass Pasture In Florida, Lynn E. Sollenberger, R. S. Kalmbacher

IGC Proceedings (1977-2023)

Soils and climate are very diverse across Florida, and no single legume has state-wide adaptation. However, aeschynomene (Aeschynomene americana), an annual, and carpon desmodium (Desmodium heterocarpon) cv. Florida, a perennial, are the most commonly used legumes for grazing on the central and southern peninsula, which produces 65% of Florida's beef calves. Both grow well with bahiagrass (Paspalum notatum), which is the main pasture grass, with ~1M ha state-wide. Circa 65K ha of bahiagrass contain at least limited quantities of aeschynomene and 14K ha contain carpon desmodium.

Rhizoma Peanut: More Than A ‘Lucerne’ For Subtropical Usa, M. J. Williams, K. H. Quesenberry, G. M. Prine, C. B. Olson Jun 2023

Rhizoma Peanut: More Than A ‘Lucerne’ For Subtropical Usa, M. J. Williams, K. H. Quesenberry, G. M. Prine, C. B. Olson

IGC Proceedings (1977-2023)

Rhizoma peanut (Arachis glabrata) was introduced to Florida from South America in the 1930s. Selections 'Arb' (PI 118457) and 'Arblick' (PI 262839) were released in the 1960s, but their use was very limited due to slow establishment and low productivity. The University of Florida released 'Florigraze' (PI 421707) in 1978 and 'Arbrook' (PI 262817) in 1986. These cultivars produced much higher dry matter yields. Thereafter, rhizoma peanut began to gain commercial acceptance. These cultivars are used throughout the Gulf Coast region of the USA for commercial hay production, pasture, creep grazing, silage, balage, and living mulch (French et …

Relative Yields And Nutritive Value Of Whole Crop Rice Harvested On Four Successive Dates For Forage In Korea, Jong-Geun Kim, Y. C. Lim, E. S. Chung, S. H. Yoon, S. Seo, M. J. Kim Jun 2023

Relative Yields And Nutritive Value Of Whole Crop Rice Harvested On Four Successive Dates For Forage In Korea, Jong-Geun Kim, Y. C. Lim, E. S. Chung, S. H. Yoon, S. Seo, M. J. Kim

IGC Proceedings (1977-2023)

About four million tons of forages are fed to ruminants in Korea, but half of them rely on rice straw as roughage and 0.6 million tons of forage was imported. The lack of forage results in increased imports of concentrate feeds and increased production cost. Now, Korea has about 1.1 million ha of rice fields, but as a consequence of world trade negotiation, Korea will open the rice market from next year. It is expected that due to aging farmers and lower rice price, about 0.2 million ha of paddy field will not be cultivated for grain rice. Therefore, we …

Nutritional Evaluation Of Banana Peelings From The Various Banana Varieties In Different Regions Of Uganda, J. Nambi-Kasozi, Elly N. Sabiiti, F. B. Bareeba, E. Sporndly Jun 2023

Nutritional Evaluation Of Banana Peelings From The Various Banana Varieties In Different Regions Of Uganda, J. Nambi-Kasozi, Elly N. Sabiiti, F. B. Bareeba, E. Sporndly

IGC Proceedings (1977-2023)

In Uganda, peri-urban agriculture is very important in sustaining livelihoods of the increasing population in urban and peri-urban (U & PU) areas. However, this form of agriculture has a number of problems, feed shortage being the most important. The agricultural produce brought in from the rural areas is marketed in raw form hence increasing the crop wastes in the market areas. The crop wastes, if properly sorted, can serve as alternative feeds for the animals kept in the U & PU areas. Banana (Musa spp) peelings (BP) constitute the largest proportion of all the crop wastes in most …

Changes In Grass Quality Of Coastal Meadows In Estonia, Tiina Köster, Karin Kauer, R. Viiralt, A. Selge Jun 2023

Changes In Grass Quality Of Coastal Meadows In Estonia, Tiina Köster, Karin Kauer, R. Viiralt, A. Selge

IGC Proceedings (1977-2023)

In Estonia the reason for reduction in coastal meadows and expansion of the stands of the common reed (Phragmites australis) is the discontinuation of traditional use of grasslands which were previously grazed and cut. Phragmites australis usually produces dense and monospecific stands at the waterline, where species richness is low. It can survive in ungrazed shore meadows, but it suffers from grazing (Tyler, 1969). The investigated Phragmitetum australis association had been influenced by grazing activities, but it remained rather sparse and due to that had relatively low productivity, reaching 3.11 t DM/ha. Traditionally coastal meadows have been used …

Diversity And Variation In Nutritive Value Of Plants Growing On 2 Saline Sites In Southwestern Australia, Hayley C. Norman, R. A. Dynes, D. G. Masters Jun 2023

Diversity And Variation In Nutritive Value Of Plants Growing On 2 Saline Sites In Southwestern Australia, Hayley C. Norman, R. A. Dynes, D. G. Masters

IGC Proceedings (1977-2023)

In south-western Australia 10% or 1.8 million ha of the farmed area is affected by dryland salinity and a further 6 million ha are at risk of salinity (NLWRA, 2001). Animal production from saltbush (Atriplex spp.)-based pasture systems represents the most likely large-scale opportunity for productive use of saline land in the short to medium term. Feeding saltbush-based pastures as a maintenance feed during the prolonged autumn feed gap typical in Mediterranean-type climates maximises their economic value. The aim of this study was to explore the diversity and nutritive value of plants that typically persist in saltbush-based saltland pastures.

Variations In Nutritive Values Of Two Different Desert Forage Plants Growing In The United Arab Emirate Environment, T. Ksiksi, A. Bamakhrama, M. Satri Jun 2023

Variations In Nutritive Values Of Two Different Desert Forage Plants Growing In The United Arab Emirate Environment, T. Ksiksi, A. Bamakhrama, M. Satri

IGC Proceedings (1977-2023)

Forage plants in desert environments have to withstand both shortages in resources and over grazing during most years. This variation in resource availability is associated with variation in the nutritive values of the plant species. Moreover, these differences are not only seasonal but also vary between plant parts. Variations in nutritive values in key species, therefore, need to be better understood in order to sustainably feed livestock (Abdurazak et al., 2000), because effective management requires adequate knowledge of the interaction between the animal, the pasture and the environment (Kassilly, 2002). Forage toxicity could, however, cause irreparable damage to production. …

Factors Affecting Forage Quality Of Native Species In Iranian Rangelands, Hossein Arzani, J. Torkan, H. Kaboli, M. Zohdi Jun 2023

Factors Affecting Forage Quality Of Native Species In Iranian Rangelands, Hossein Arzani, J. Torkan, H. Kaboli, M. Zohdi

IGC Proceedings (1977-2023)

Animal performance is closely correlated with the nutrient value of the forage available and this is affected by different factors (Arzani et al., 2001). Crude protein content (CP), digestible dry matter (DDM) and metabolisable energy (ME) were considered particularly appropriate for evaluation of range forage quality. This paper reports on factors affecting the forage quality of range species grown in Iran.

Determination And Comparison Of Forage Quality Of Five Species In Different Phenological Stages In Alborz Rangelands (Iran), A. Ahmadi, Hossein Arzani, A. A. Jaafari Jun 2023

Determination And Comparison Of Forage Quality Of Five Species In Different Phenological Stages In Alborz Rangelands (Iran), A. Ahmadi, Hossein Arzani, A. A. Jaafari

IGC Proceedings (1977-2023)

In order to evaluate grazing capacity and integrated management of rangelands and grasslands , it is necessary to be aware of the quality of range plants. Phenological (growth) stage has the greatest effect on forage quality with most of the qualitative indices decreasing with the progress of the phenological stage (Holecheck et al., 2001). This research studied the changes in forage quality for species in the Alborz rangelands.

Variation In The Quality Of Forage Of Six Rangeland Species In Different Phenological Stages, Zeid Ahmadi, H. Arzani, Hossein Azarnivand Jun 2023

Variation In The Quality Of Forage Of Six Rangeland Species In Different Phenological Stages, Zeid Ahmadi, H. Arzani, Hossein Azarnivand

IGC Proceedings (1977-2023)

An understanding of forage quality is fundamental to the measurement of grazing capacity. In addition, knowledge of forage quality is necessary for planning grazing and developing range improvement and development programmes, such as planting and seeding of rangelands. Among the different factors that affect forage quality, phenological stage is particularly important (Cook, 1972; Caballero et al.,2001). The objective of this study was to investigate the effects of plant species, phenological stages and life form on forage quality indices.

Water-Soluble Carbohydrate (Wsc) Concentrations In Ireland And Norway Of Lolium Perenne Differing In Wsc Genotype And Receiving Varying Rates Of N Fertiliser, P. O'Kiely, L. Nesheim, P. Conaghan, F. P. O'Mara Jun 2023

Water-Soluble Carbohydrate (Wsc) Concentrations In Ireland And Norway Of Lolium Perenne Differing In Wsc Genotype And Receiving Varying Rates Of N Fertiliser, P. O'Kiely, L. Nesheim, P. Conaghan, F. P. O'Mara

IGC Proceedings (1977-2023)

Cultivars bred for elevated water-soluble carbohydrate (WSC) concentration may have improved grass ensilability and nutritive value. Increasing rates of application of N fertiliser generally reduce grass WSC concentration, although it is unknown if the response is similar for normal and elevated WSC genotypes or if these factors interact with growing conditions. This experiment evaluated the effects on grass WSC concentration of varying N fertiliser application rates to perennial ryegrass cultivars of high or normal WSC genotype grown in Ireland and Norway.

Proanthocyanidins From Hedysarum, Lotus And Onobrychis Spp. Growing In Sardinia And Sicily And Their Antioxidant Activity, A. Tava, M. G. De Begedetto, D. Tedesco, G. Di Miceli, G. Piluzza Jun 2023

Proanthocyanidins From Hedysarum, Lotus And Onobrychis Spp. Growing In Sardinia And Sicily And Their Antioxidant Activity, A. Tava, M. G. De Begedetto, D. Tedesco, G. Di Miceli, G. Piluzza

IGC Proceedings (1977-2023)

Proanthocyanidins (PA), or condensed tannins, are a class of natural polyphenolic compounds, occurring in numerous plant species, including a number of economically significant forage legumes. These compounds are polymers of flavan-3-ols, and typically contain from 2 to 20 units. Their biological significance is still being debated and, in recent years, a great deal of attention has been focused on their role in ruminant nutrition. Evidence has indicated that PA, in a moderate concentration (0.5-5% DM), may have considerable importance in protecting dietary proteins against microbial degradation in the rumen, and in preventing bloat. The antioxidant activity (AA) is also an …

Predicting Intake From Indigestible Fibre, Kenneth J. Moore, J. R. Russell Jun 2023

Predicting Intake From Indigestible Fibre, Kenneth J. Moore, J. R. Russell

IGC Proceedings (1977-2023)

Dry matter intake (DMI) of forages is often estimated as a reciprocal function of fibre concentration: DMI = fibre intake capacity / dietary fibre concentration (Mertens, 1987). This theoretical relationship is based on the concept that consumption of forage diets is limited by fill and that fibre represents the bulk of forage diets. This model, however, does not account for differences in DMI which should occur among forages with similar fibre concentrations but differing fibre digestibility. To account for these differences, we proposed an intake model where DMI is a reciprocal function of indigestible fibre concentration: DMI = c / …

Validation Of Faecal Nirs For Monitoring The Diet Of Confined And Grazing Goats, S. Y. Landau, T. A. Glasser, L. Dvash, Avi Perevolotsky Jun 2023

Validation Of Faecal Nirs For Monitoring The Diet Of Confined And Grazing Goats, S. Y. Landau, T. A. Glasser, L. Dvash, Avi Perevolotsky

IGC Proceedings (1977-2023)

Goats are used for brush control and ecological management of Mediterranean grazing lands. Farmers are willing to cooperate with communities but they need an easy method to evaluate the daily intake of nutrients. A calibration of the chemical attributes of goats' diets was set-up, based on faecal near infrared (NIR) spectra (Landau et al., 2004; Table 1). The accuracy of this methodology was estimated by using the standard error of cross-validation (SECV), which represents the variability in the difference between predicted and reference values when the equation is applied sequentially to subsets of data from the calibration data set. …

Near Infrared Spectroscopy To Assess Feeding Value And Antinutritional Compounds In Legume Species, M. Odoardi, S. Colombini, G. Piluzza, M. Confalonieri

IGC Proceedings (1977-2023)

There is an increasing demand for information on the quality characteristics and chemical composition of forages in order to meet the demands of dietary specifications for feeding animals. Near Infrared (NIR) spectroscopy provides a tool for rapid and non-destructive analysis in agronomic and breeding programs of a number of chemical components of forages and grains. NIR spectroscopy in particular has the advantage of being able to simultaneously evaluate the samples for a number of qualitative traits of whole plants and seeds. In two experiments here presented, NIR Spectroscopy was used to predict: i) qualitative characteristics of field pea seeds and, …

Sample Preparation Method For Near Infrared Reflectance Spectroscopy To Predict Fermentation Quality Of Maize Silage, H. S. Park, J. K. Lee, M. C. Kim Jun 2023

Sample Preparation Method For Near Infrared Reflectance Spectroscopy To Predict Fermentation Quality Of Maize Silage, H. S. Park, J. K. Lee, M. C. Kim

IGC Proceedings (1977-2023)

Using NIRS directly on undried silage can increase error due to variability in sample particle size, temperature and water content (Givens et al., 1997). These problems can be overcome by grinding silages in frozen state with dry ice or liquid nitrogen, but such procedures are time-consuming and inconvenient due to cleanup required between samples and the need to thaw the sample for subsequent use. The objective of this experiment was to assess the effect of sample preparation methods on prediction of fermentation quality of maize silage, and to select an acceptable sample-preparation method for wet silage.

A Rapid Estimation Of Nitrogen Bound To Neutral Detergent Fibre In Forages By Near Infrared Reflectance Spectroscopy, Jérôme Bindelle, G. Sinnaeve, P. Dardenne, P. Leterme, A. Buldgen Jun 2023

A Rapid Estimation Of Nitrogen Bound To Neutral Detergent Fibre In Forages By Near Infrared Reflectance Spectroscopy, Jérôme Bindelle, G. Sinnaeve, P. Dardenne, P. Leterme, A. Buldgen

IGC Proceedings (1977-2023)

Near infrared reflectance spectroscopy (NIRS) is widely used as a rapid method for the evaluation of the chemical composition or the nutritive value of foodstuffs (Givens et al., 1997). The determination of the neutral detergent fibre (NDF) bound N (NDF-N), which is highly variable in forages (Shayo & Udén, 1999), is expensive. The purpose of this study was to test the use of NIRS in the prediction of NDF-N in various forages.

IGC Proceedings (1977-2023)

Over the past five years, Foss and DeLaval have sponsored the activities of a group of forage analysts with the aim of developing "global" Near Infrared (NIR) calibrations for parameters that are important in ruminant nutrition. The approach adopted has been based on the amalgamation of historical databases from centres worldwide and calibrations for protein and neutral detergent fibre (NDF) in dried ground forages have been developed based on databases that currently comprise approximately 30,000 records. Protein and NDF, while not the most important parameters in ruminant nutrition, were chosen for the initial calibration development exercise because of the amount …

Forage Quality As Related To Mineral Concentrations In Tropical Regions, L. R. Mcdowell Jun 2023

Forage Quality As Related To Mineral Concentrations In Tropical Regions, L. R. Mcdowell

IGC Proceedings (1977-2023)

Often tropical forages contain deficient or toxic concentrations of minerals for grazing livestock (McDowell, 2003). Tropical forages generally contain less of the more essential minerals than species grown in temperate regions (McDowell & Valle, 2000). Mineral elements in forages are dependent upon the interaction of a number of factors, including soil, plant species, stage of maturity, yield, pasture management and climate. The objective of this study was to determine the adequacy of minerals for ruminants in forages collected from seven tropical countries.

Mineral Status Of Some Permanent Range Plants For Grazing Sheep In Semi-Arid Areas Of The Chaharmahal And Bakhtiari Province In Iran. 2. Trace Minerals, G. H. R. Shadnoush Jun 2023

Mineral Status Of Some Permanent Range Plants For Grazing Sheep In Semi-Arid Areas Of The Chaharmahal And Bakhtiari Province In Iran. 2. Trace Minerals, G. H. R. Shadnoush

IGC Proceedings (1977-2023)

The principal factors limiting the performance of grazing animals are low protein content of grasses, low energy intake due to high fibre content and mineral deficiencies or imbalances (McDowell, 1985). At least 26 mineral elements are required by at least one animal species (Church et al., 1988). These elements are generally required in small amounts. They have a great deal of importance for body tissue growth as well as for physiological functions. Mineral deficiencies and imbalances have been reported from almost all tropical regions of the world. This study was designed to measure the copper, iron, manganese and zinc …

Mineral Status Of Some Permanent Range Plants For Grazing Sheep In Semi-Arid Areas Of The Chaharmahal And Bakhtiari Province In Iran. 1. Some Macro Minerals, G. H. R. Shadnoush

IGC Proceedings (1977-2023)

A deficiency of one or more of the essential minerals in animals can lead not only to a decrease in productivity but also to metabolic diseases in case of severe deficiencies (McDowell, 1985). In general, mineral, especially phosphorous, deficiencies and imbalances are reported from almost all tropical regions of the world (Matijovic & Durackova, 1994). This study was designed to measure the calcium, phosphorous, magnesium, potassium, sodium and chlorine contents of some plant species in the semi-arid rangeland of Chaharmahal & Bakhtiari Province in Iran, because little information is available at present.

Use Of Green Sulla Forage For Feeding. 2. Effects On Lamb Carcass And Meat Quality, A. Bonanno, M. L. Alicata, G. Tornambè, F. Mazza, G. Di Miceli, D. Giambalvo Jun 2023

Use Of Green Sulla Forage For Feeding. 2. Effects On Lamb Carcass And Meat Quality, A. Bonanno, M. L. Alicata, G. Tornambè, F. Mazza, G. Di Miceli, D. Giambalvo

IGC Proceedings (1977-2023)

Diets with 2.5% of condensed tannins (CT) from carob pulp have been showed to reduce lamb carcass weight, yield and fatness, as a consequence of lower digestibility due to strong protein-tannin bonds. Moreover the diets lightened meat colour and negatively affected meat sensory properties (Priolo et al., 2000). There is evidence that some tannin-rich legumes have weaker stability of the protein-tannin complex post-rumen (McSweeney et al., 2001). Since the CT-containing sulla (Hedysarum coronarium L.) demonstrated improved lamb growth performance in comparison with CT-lacking annual ryegrass (Lolium multiflorum Lam. subsp. wersterwoldicum) (Giambalvo et al., 2005), …

Use Of Green Sulla Forage For Feeding. 1. Effects On Lamb Growth And Gastrointestinal Nematode Parasite Infestation, D. Giambalvo, A. Di Grigoli, M. L. Alicata, B. Formoso, A. S. Frenda, P. Trapani Jun 2023

Use Of Green Sulla Forage For Feeding. 1. Effects On Lamb Growth And Gastrointestinal Nematode Parasite Infestation, D. Giambalvo, A. Di Grigoli, M. L. Alicata, B. Formoso, A. S. Frenda, P. Trapani

IGC Proceedings (1977-2023)

Recent studies have shown that some forage legumes containing condensed tannins (CT), such as sulla (Hedysarum coronarium L.), can reduce the gastrointestinal nematode burden in sheep (Niezen et al., 1998) and increase post-ruminal protein availability (Waghorn et al., 1994). This study aimed to evaluate the anthelmintic and nutritional properties of sulla forage in relation to its CT content. Thus, the growth performance and the level of nematode infestation of lambs fed sulla were compared with those of lambs fed ryegrass (Lolium multiflorum Lam. subsp. wersterwoldicum), lacking in CT.
