Effect Of Selected Tanniniferous Leaves On In Vivo Enteric Methane Emission In Sheep, M. Saravanan, R. Bhatta, L. Baruah, P. K. Malik, N. Ravi
IGC Proceedings (1997-2023)
Concentration of methane is continuously increasing in atmosphere and now almost 155% (IPCC, 2007) more than that recorded during pre-industrial era. Livestock production is a major sector accountable for high methane emission into atmospheric pool. World’s livestock is contributing around 15% of total atmospheric methane on annual basis feeds (Moss et al., 2000). Additionally, methane emission from ruminants leads to a loss of 2 to 15% of the dietary energy (Holter and Young, 1992). Due to these two crucial issues, researchers are working tirelessly to find a suitable and effective way for enteric methane amelioration accompanied with minimal inputs. …

Perennial grasses are high yielding, pest resistant and less demanding in terms of soil (Peeters, 2008), they are the most important source of roughage. Each species has certain valuable features that make it unique among others and which are desirable to be highlighted for ensuring high productivity, good forage quality, plasticity, strength of various stress conditions, as well as winter hardiness, which is particularly important characteristic of northern latitudes. It is the main task of breeders, as far as possible to combine all the aforesaid properties into one breed. In order to create such a universal variety the breeders of …

IGC Proceedings (1997-2023)
Shortage of quality feed is a persistent livestock productivity constraint and it is accentuated by climate variability and increased unpredictability of precipitation in many areas in Sub-Saharan Africa. Improved Brachiaria genotypes are some of the interventions that can improve feed security and contribute to the global climate change mitigation efforts.
Use Of Monsoon Herbage (Amaranthus Spp.) In Complete Feed Block For Sheep Feeding, R. S. Bhatt, A. Sahoo, S. K. Sankhyan
Use Of Monsoon Herbage (Amaranthus Spp.) In Complete Feed Block For Sheep Feeding, R. S. Bhatt, A. Sahoo, S. K. Sankhyan
IGC Proceedings (1997-2023)
Favourable climatic condition and faster vegetation growth during monsoon season leads to abundance of forage production, which remained mostly unutilized by the grazing herbivores. Chaulai (Amaranthus spp) is one of the local green biomass that grows very fast after first monsoon shower and is not preferably grazed in comparison to other available grazing resources during monsoon. A huge quantity (dry biomass yield of approximately 10-15 Q/ha) of this biomass is therefore gone waste in due course, not being harvested or utilized. This plant is quite rich in protein (CP 10-14%) with succulent leaves and tender stems and has varying palatability …

Nutritive Value And Cattle Preferences In An Old Boer Lovegrass Stand Treated With Biosolids In Cananea, Sonora, México, Salomón M. Moreno, Martha R. Martin, Fernando Ibarra, Roque Martínez, Agustín Cabral Martell, Francisco B. Denogean, Rafael Retes
IGC Proceedings (1997-2023)
Boer lovegrass (Eragrostis curvula var. conferta) is an introduced species planted to increase productivity on deteriorated rangelands in northern Mexico. Forage production with Boer lovegrass achieves an increase of two to three fold when compared to native grasses, however, as stands became old, pasture productivity and forage quality declines due to a reduction in available nutrients causing a reduction in grazing capacity and beef production. Previous studies have shown that biosolids enhance seedling establishment, plant growth and increases forage production in the species, but no data is available to measure changes in forage quality and animal performance. This …

Re-Growth Yield And Nutritive Value Of Winter Cereals, Gurhan Keles, Serkan Ates, Behic Coskun, Saban Koc
IGC Proceedings (1997-2023)
Cereal crops can be grazed in early winter or early spring when feed is scarce, or to utilize their high feeding value. In the early spring of 2011, the re-growth yield and nutritive value of barley (Hordeum vulgare L.), rye (Secale cereale L.), wheat (Triticum aestivum), oat (Avena sativa L.), and triticale (x Triticosecale Wittmack) grown in the Central Anatolian Region of Turkey, were evaluated after three successive weekly harvests (Cut 1, Cut 2, Cut 3) during the tillering to stem elongation stages. Plants were cut at a height of 5 cm then allowed …

The grass plant is comprised of leaf blades, leaf sheath (pseudostem), true stem and dead material each differing in digestibility and their relative proportions can impact significantly on sward quality. The objective of this study was to determine the change in the proportion and organic matter digestibility (OMD) of leaf, pseudostem, true stem and dead fractions of four perennial ryegrass cultivars throughout a grazing season.
Forage Quality And Defoliation Interval In Tall Fescue Cultivars, Mónica G. Agnusdei, Juan Ramón Insúa, Oscar Norberto Di Marco
Forage Quality And Defoliation Interval In Tall Fescue Cultivars, Mónica G. Agnusdei, Juan Ramón Insúa, Oscar Norberto Di Marco
IGC Proceedings (1997-2023)
Past research has shown digestibility decreases along leaf lifespan (LLS) in several grasses (i.e. Groot and Neute-boom 1997; Insúa et al. 2013; Agnusdei et al. 2012). This phenomenon has not yet been quantified in tall fescue (Festuca arundinacea Schreb.). Therefore, additional knowledge on the dynamics of leaf quality decline along LLS is necessary to verify the proper defoliation window necessary to optimize forage quality and production (Fulkerson and Donaghy 2001; Lemaire et al. 2009) in tall fescue. Further, this window might differ between old and new types (i.e. softer vs rough-leaved). The …

Forage Quality Indices Of Some Important Grass Species Of Iranian Rangelands, Hossein Arzani, Javad Motamedi, Mohammad Ali Zarechahouki
IGC Proceedings (1997-2023)
To be informed of the forage quality indices is one of the fundamental essentials for determination of the amount of forage sufficient for the daily requirements of animal in rangelands and wildlife habitats. This amount would be different depending on the vegetative composition and consequently the forage quality (Arzani, 2009). In this regard, grasses are considered one of the most important plants in the vegetative composition of rangelands in the country’s different climate zones that are grazed by the animals and meet a considerable amount of animal requirements (Arzani et al. 2010). Therefore, the values of forage quality indices …

IGC Proceedings (1997-2023)
It is imperative to find alternative source(s) of feed for livestock in lieu of the limited availability of conventional concentrates and the competition for this resource by man. One plant with great potential for the livestock is bitter leaf (Vernonia amygdalina). It is wide spread with about 200 species, is edible, drought tolerant, nutritious and has been found to have medicinal qualities (John 1994). V. amygdalina has an astringent taste which affects its intake. Bitter leaf meal contains 20-34% crude protein (CP) and can be used as protein supplement (Aregheore et al. 1998). With the recent introduction …
