Lactating Ewes Were Strongly Attracted To Salt When Spread On Sodium-Deficient Undergrazed Hill Pastures, N. Mandaluniz, J. C. Ruiz, R. J. Lucas

IGC Proceedings (1977-2023)

New Zealand hill and high country pastures for sheep and cattle cover very variable topography. Shady south face hill country pastures on steeper slopes are grazed inefficiently because of their mature state and low nutritive value. Flatter more fertile areas reflect more frequent defoliation and stock camping behaviour. These inland pastures are deficient in sodium (Na) (Aspinall et al., 2004) because they are distant from coastal sea spray. Management alternatives are sought to improve pasture quality on steep, shady aspects. The provision of different nutrients such as Na or nitrogen (N), which are deficient in these under-grazed areas of …

Intake By Lactating Goats Browsing On Mediterranean Shrubland, M. Decandia, G. Pinna, A. Cabiddu, G. Molle

IGC Proceedings (1977-2023)

In Mediterranean regions goat feeding systems are mainly based on shrubland that contain a wide variety of species. There are only a few equations for predicting feed intake of stall-fed goats (Luo et al., 2004). The objective of this study was to develop a model for predicting the intake of lactating goats browsing on Mediterranean shrubland.

Metabolic Profiling Of Heathland Plants In The Diet Of Sheep, Gordon G. Allison, Mariecia D. Fraser, J. M. Moorby, J. Kopka, A. Erban, Vince J. Theobald

IGC Proceedings (1977-2023)

Little is known about how plant biochemistry influences the grazing behaviour of animals grazing heterogeneous vegetation communities. Furthermore, most biochemical profiles of grassland species are restricted to major nutritional characteristics. Recent developments in analytical techniques have made possible the detailed analysis of minor components, which can potentially affect animal feeding preferences, performance and health. Gas chromatography/time of flight mass spectroscopy (GC/TOF-MS) coupled with automated library annotation is ideally suited to the acquisition of detailed metabolite profiles of plant extracts (Wagner et al., 2003) and can be applied to other matrices such as blood and faeces. In this study GC/TOF-MS …

Grazing Behaviour And Selection Of Browse Species By Cattle, Sheep And Goats On Natural Pasture In The Sahelian Zone Of Burkina Faso, H. O. Sanon, C. Zoungrana-Kabore, I. Ledin

IGC Proceedings (1977-2023)

Pastures in semi-arid countries, are subject to seasonal variability. Browse species that are less dependent on rainfall, are highly valued. Goats are browsers, while cattle and sheep are grazers. However, faced with a scarcity of feed resources, especially in the late dry season, all animal species fall back on browse species. The objective of this study was to estimate feeding behaviour and browse species utilisation by cattle, sheep and goats on natural pasture in different seasons, and concurrently appreciate the indigenous knowledge on browse species in the study area.

Grazing Preference, Herbage Production And Quality Of Diploid And Tetraploid Lolium Perenne Cultivars In Southern Chile, Oscar A. Balocchi, Ignacio F. López

IGC Proceedings (1977-2023)

Lolium perenne is the most important plant species used in sown pasture in Southern Chile. Cultivars used are mainly diploid. However, in recent years some tetraploid cultivars have been introduced into the country. The objective of the study was to determine the effect of the ploidy of the cultivars on herbage production, nutritive value, grazing preference and utilisation of the herbage.

Effect Of Dairy Effluent On Turnip Nutritive Characteristics, Joe L. Jacobs, G. N. Ward, Frank R. Mckenzie

IGC Proceedings (1977-2023)

In southern Victoria, high summer temperatures and low rainfall lead to low pasture growth and a decline in nutritional value until rainfall commences in autumn. Annual forage crops such as turnips often are used to fill the summer feed gap. Jacobs & Ward (2003) observed that dairy effluent applied at low rates could improve turnip DM yields and crude protein content. Results from the first two years of a 3-year study comparing a range of effluent application rates on turnip leaf and root nutritive characteristics are reported.

IGC Proceedings (1977-2023)

The smallholder cattle systems of the Toluca valley in central Mexico are based on the use of maize and native grasses. Research has been devoted to nutritional characterisation of improved pastures, but native species of grasses have not been studied, despite their importance. The aim of this experiment was to evaluate the in vitro rumen degradation kinetics of four species of native pastures.

The Impact Of Continuous Grazing By Free Ranging Sheep On The Structure And Botanical Composition Of Grassland As Determined By Multivariate Analysis, G. A. Heshmati

IGC Proceedings (1977-2023)

Grazing shapes the botanical composition of vegetation at the landscape level (Oksanen et al., 1995). Sheep seek spatially scattered plants of nearly constant and high nutritional value. There is strong interaction between the grazing behaviour of the sheep and the structure of the plant community that it grazes (Squires, 1981). This paper examines the situation in a grassland vegetation grazed by free-ranging sheep in a semi arid region of North Eastern Iran.

Effects Of Vegetation Structure And Plant Height When Grazed On Persistency Of Meadow Fescue Pasture, K. Sudo, Y. Ogawa, K. Umemura

IGC Proceedings (1977-2023)

An intensive grazing technique using meadow fescue (Mf) pasture has been developed in northern Japan, where soil freezes in winter. It has been shown that the appropriate plant height of Mf pasture when grazed for persistency is about 27 cm. When Mf and perennial ryegrass (Pr) pastures were grazed at the same plant height of 20 cm, vegetation of Mf pasture declined and plant length of Mf pasture was longer than that of Pr pasture (Sudo et al., 2002). These phenomena might be due to the effects of differences in grass species and plant height when grazed on vegetation …

Intake, Digestibility And Rate Of Passage Of Grass In Grazing By Light Breed Horses On Different Pastures, Masahito Kawai, N. Yabu, T. Asa, K. Deguchi, S. Matsuoka

IGC Proceedings (1977-2023)

In a previous study, grazing light breed horses could ingest CP and DE requirements for maintenance without supplements. However, their grazing behaviour, such as biting and chewing efficiency, which related to the passage rate of forage in the digestive tract and fibre digestibility, was affected by the pasture conditions (Kawai et al., 2004). In this study, the DM intake, digestibility and mean retention time (MRT) of grass in light breed horses were determined and compared in spring, summer and autumn on an improved pasture.

Effect Of Red And White Clover Added To A Rye Grass-Based Diet On Intake, Fibre Digestion And Methane Release Of Dairy Cows, Anette H. Van Dorland, Michael Kreuzer, M. Leuenberger, H. R. Wettstein

IGC Proceedings (1977-2023)

Forage legumes like white and red clover are widely grown in association with grass, with the intention to improve the quality of grass-based diets. However little is known about the effect of either white or red clover added to a grass-based diet on methane release, and existing studies are not conclusive. The objective of this study, applying the respiratory chamber technique, was to determine the effect of red and white clover added to a rye grass-based diet on intake, fibre digestion and methane release of dairy cows.

Proanthocyanidins From Hedysarum, Lotus And Onobrychis Spp. Growing In Sardinia And Sicily And Their Antioxidant Activity, A. Tava, M. G. De Benedetto, 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 …

Diet Selection In A Pasture Of Panicum Maximum Cv. Mombaça With Different Sward Heights, Teresa C. M. Genro, Ê. R. Prates, F. F. Cardoso, L. R. L. San'thiago

IGC Proceedings (1977-2023)

The n-alkane method allows to measure dry matter (DM) intake and to determine the proportion of grass and legume ingested by ruminants grazing mixed pastures. Dove & Mayes (1996) pointed out that using this method, beyond estimating intake of individual plant species, it may also be possible to determine intake of anatomical components of the plant. The aim of this work was to use the non-negative least squares procedure to estimate diet selection based on plant alkanes and animal faeces.

Theoretical Considerations On A One-Parameter Approach To Compare Actual And Estimated Compositions Of Multi-Component Diets, C. Elwert, M. Rodehutscord

IGC Proceedings (1977-2023)

The composition of ingested herbage mixtures can be estimated using the alkane technique (Dove & Moore, 1995), with the accuracy of the estimate assessed by linear regression of estimated and actual proportions of the dietary components (Dove, 1992). However, although the linear regression might not differ from the line of equality, large discrepancies may occur within individual components (Hoebee et al., 1998). This paper presents an approach to compare actual and estimated diet compositions using only one parameter.

An Evaluation Of The N-Alkane Technique For Determining Diet Composition In Animals Grazing Complex Swards, M. D. Fraser, J. M. Moorby, V. J. Theobald, R. Jones

IGC Proceedings (1977-2023)

The n-alkane profiles of epicuticular waxes derived from different plant species are sufficiently distinct to allow assessment of the proportions of different herbages in two-component mixtures including perennial ryegrass/white clover, heather/hill grass and rush/perennial ryegrass (Dove & Mayes, 1996). Evidence suggests the reliability of such estimates declines as the number of different dietary components increases. However, recent studies have shown analysis of additional compounds, including long-chain fatty alcohols, may improve discrimination between different dietary components. The aim of this experiment was to quantify the accuracy of such methods for determining the diet composition of animals grazing complex swards.

Using The N-Alkane Technique To Estimate The Herbage Intake And Diet Composition Of Cattle Grazing A Miscanthus Sinensis Grassland, Y. J. Zhang, Y. Togamura, K. Otsuki

IGC Proceedings (1977-2023)

Plant wax alkanes are now widely used as marker substances (Dove & Mayes 1991) for the estimation of forage intake and diet composition of grazing herbivores. The objective of this study was to evaluate this method with cattle grazing a M. sinensis grassland in Japan.
