Calcium And Phosphorus Ratio In Soil, Native Grasses, Water And Bovines And Its Correlation With Productivity, Anandamoy Kundu, Jaisunder, S. Jeya Kumar, R. B. Rai

IGC Proceedings (1977-2023)

Minerals play vital role in growth, sexual maturity, conception and milk production. Reproductive problems viz. delayed puberty in heifers, post pubertal anoestrus, repeat breeding and prolonged post partum anestrous, prolonged service period and calving interval in cattle has been observed to be a major cause for poor productive and reproductive performance under this island ecosystem. Therefore, the study was undertaken to correlate the extent to which calcium and Phosphorus were responsible for reproductive performance of bovines. In Andaman & Nicobar Islands, the concentrate feeding to bovines is uncommon. Thus bovines are fully dependent on grazing or forage feeding. Most of …

IGC Proceedings (1977-2023)

Xenobiotics like heavy metals are increasing in environment due to industrialization, urbanization and agricultural practices which pose threat to animal health and quality animal products. Safe animal feeds are important for health of animals, environment and for the safety of foods of animal origin especially milk (Prasad et al., 2012). To address the issue, monitoring of xenobiotics especially heavy metals in the fodder, feeds and animal products is necessary. The aim of the present study is to find out the status of heavy metals in feeds and milk of Gulbarga district in Karnataka.

Effect Of Arbuscular Mycorrhizae On Nutrient Content And Seedling Quality Of Important Fodder Tree Species Of Central India, Ashok Shukla, Anuradha Jha, Anil Kumar, V. D. Tripathi

IGC Proceedings (1977-2023)

Acacia nilotica, Albizia procera, Dalbergia sissoo and Leucaena leucocephala are important multipurpose tree species (MPTs). These are being utilized in agroforestry systems at ICAR-Central Agroforestry Research Institute (ICARCAFRI), Jhansi and are also being utilized in reforestation programme in Central India. The success of any agroforestry model and/or reforestation programme depends upon the quality seedling materials. Nursery-produced seedlings can be an effective means of ensuring successful establishment of agroforestry models and/or reforestation programme. However, such seedlings sometimes fail to establish themselves in the fields. The poor performance of planted seedlings is often associated with transplant shocks and low seedling …

Endophytes For Improving Ryegrass Performance: Current Status And Future Possibilities, Alison J. Popay, David E. Hume

IGC Proceedings (1977-2023)

The endophyte N. lolii was introduced naturally into New Zealand and Australia when perennial ryegrass seed was brought into these countries. Although the presence of the endophyte was recognised early in the 19^th Century, its effects were only discovered in the early 1980s when it was found that these Wild-type strains of endophyte caused ryegrass staggers, a neuromuscular condition of grazing animals (Fletcher and Harvey 1981), and that they also protected their hosts from the effects of Argentine stem weevil (Listronotus bonariensis) a serious pest of ryegrass in New Zealand (Prestidge et al. 1982). These endophytes …

Mineral Status Of Livestock, Soil, Feeds And Fodders In Ajmer District Of Rajasthan, Sheela Choudhary, Ramkesh Meena, Sunil Dutt Choudhary, Poonam Yadav

IGC Proceedings (1977-2023)

A large number of Indian livestock suffer from deficiencies or imbalances in minerals because they are mainly maintained on crop residue based rations and grazing without access to mineral supplement (Mc Dowell et al., 1993). Deficiency or imbalance of single or multiple minerals results in enzymatic dysfunction and hormonal imbalance associated with fertility of animals (Maurice, 2003). In India where dietary concentration of fodder fed to the animals are unknown or highly variable due to availability, season, location, forage, species and animal potential (Sharma et al., 2003), it is important to determine plasma mineral concentrations in animal region wise, …

Prescribed Fire: A Proposed Management Tool To Facilitate Black-Tailed Prairie Dog (Cynomys Ludovicianus) Colony Expansion, Felicia D. Archuleta, Paulette L. Ford

IGC Proceedings (1977-2023)

Black-tailed prairie dogs (Cynomys ludovicianus) are considered a keystone species in grassland ecosystems. Through their burrowing activities, they conspicuously alter grassland landscapes and provide foraging, shelter and nesting habitat for a diverse array of grassland species, in addition to serving as prey for the endangered black-footed ferret (Mustela nigripes). Due to a combination of factors, the lands currently occupied by prairie dog colonies are thought to represent less than 10% of their historical range. Black-tailed prairie dogs have difficulty colonizing areas with tall and/or dense plant cover. We examine how manipulations of grassland vegetative structure through …

Influence Of Foliar Nutrition Of Selenium On Phytochelatines Content In The Forage Of Red Clover (Trifolium Pratense L.), Iva Klusoňová, Pavel Horký, Jiří Skládanka, Markéta Komínková, Vojtěch Adam, René Kizek, Petr Škarpa, Lucia Hodulíková

IGC Proceedings (1977-2023)

Selenium (Se) is an essential element significantly influencing health status of animals and humans. The insufficient supply of organism with this element leads to many disorders. Conversely, higher intake can be toxic. As a part of selenoproteins, it regulates the antioxidant system and thus prevents the oxidative destruction of biological membranes and prevents the damage of the body by heavy metals. Consequently, its deficiency disrupts the overall health of animals and humans because of involvement of selenium compounds in many biological functions. Selenium concentration of plant biomass is derived from its content in the soil and may considerably vary depending …

Some 63 species are introduced belonging to 37 genera and 9 families. Compared to other deserts of the world, this desert has higher number of endemic species, i.e. 6.4%. Poaceae and Leguminosae are the largest species. All these species have typical habitat-plant cover …

Strategies On Poisonous Plants Problem In China, Xinlei Gao, Mengli Zhao, Jing Wang, Bin Han, Walter D. Willms

IGC Proceedings (1977-2023)

Poisonous plants are widely distributed on large areas of native grasslands of China, causing livestock poisoning and grassland degradation, which severely impacts the development of animal husbandry. Of the almost 300 poisonous species that are responsible for livestock losses in China, locoweed, drunken horse grass and Langdu cause the greatest impact. Many strategies have been developed to minimise the impact of poisonous plants including the treatment of livestock that have been poisoned, controlling poisonous plants and managing livestock grazing. Both physical and chemical traditional methods are still used to eliminate poisonous plants while biological control using specific insects may eventually …

Mechanics Of Combining Divergent Herbivores In Cultivated Pastures, James P. Muir, William D. Pitman, José C. B. Dubeux Jr., Jamie L. Foster, Mércia V. F. Dos Santos

IGC Proceedings (1977-2023)

Sustainable intensification of cultivated pastures is needed in ruminant production if we are to feed a growing world population expected to exceed 9 billion by 2050. Planting pastures of diverse, and therefore more productive and resilient, plant species has been proposed and researched. Despite illustrative examples from wild grasslands (Hofmann, 1989) and rangelands (Glimp, 1988), very little research and even less application of multiple herbivore species (MHS) in cultivated pastures has followed. We review the specific mechanics of divergent domesticated ruminants and theorize how these could best be combined to sustainably intensify meat, milk and fiber production from cultivated pastures …

Effect Of Grazing On Soil Fertility And Trace Elements Of Temperate Desert Steppe In Northwestern China, T. Jiao, J. P. Wu, W. X. Cao, J. Qi, S. G. Zhao

IGC Proceedings (1977-2023)

Grazing is the dominant land use of temperate desert steppe in northwestern China. It is well established that the grazing process has impacts on plant production and biodiversity (Li 1997), but less is known about the effects of grazing chemical characteristics of grassland soils. Livestock feeding activities, especially the provision of supplementary sources, may influence pasture nutrient cycle, and in turn change the chemical composition of the grassland soil (Rong et al. 2001). Soil fertility may be affected by the type use and grazing intensities because these may cause alterations in soil physical and chemical properties as well as …

Effects Of Se And Co Combined Fertilizer On Production Of Alfalfa, Xiao Guo, Xiao-Lei Jie, Hua-Feng Hu

IGC Proceedings (1977-2023)

Selenium(Se) and cobalt (Co) are important essential trace elements for forage and animal production (Yang et al. 1998, Arvy 1993). The supplementation of Se in animal diet significantly increases Se-Glutathione peroxidase (GSH-Px ) activities in the liver, testes, spermatozoa and seminal plasma (Abdelrahman et al.1998), Selenium is also a key component of a number of functional seleno-proteins. GSH-Px is the best characterized of the family of selenoproteins. In Henan Province, the fine grass and green milk production zones are mainly distributed along the riverbank of the Yellow River where soils are sandy and sterile with lower Se and Co …

Short-Term Effects Of Phosphorus Application On Phosphorus Content In Soil And Dominant Species Under Ungrazed And Grazed Conditions In The Tibetan Plateau, Yajing Guo, Zhengang Guo, Yuying Shen, Xianzhi Wang

IGC Proceedings (1977-2023)

Phosphorus (P) availability in soils is an important indicator for health and growth in plants. The available phosphorus (AP) content of alpine meadow soil in northern China is low. Previous studies of alpine meadow have reported that soil nutrient levels have been significantly improved after a 9-year enclosure (Wu et al. 2010b) whereas continuous grazing over 19 years reduced total P (TP) by 25% in a Leymus chinensis steppe (Li 2001). Many studies have shown that the application of P fertilizer can improve dry matter production and forage quality in cultivated grasslands (Shi et al. 2007). However, the …

Effect Of Growth Stage On The Macro Mineral Concentrations Of Forbs And Grasses In A Semi-Arid Region Of Sudan, Sahar Ezzat, Babo Fadlalla

IGC Proceedings (1977-2023)

Ruminants grazing forages in severely mineral-deficient areas may be more restricted by this condition than by inadequacy of energy or protein. Mineral imbalances in soils and forages are responsible for low production and reproduction in grazing livestock. As grazing livestock are not usually offered mineral supplements apart from common salt, they depend upon forages for their requirements. However forages rarely fully satisfy all mineral requirements. Mineral intakes of livestock are influenced by the factors that determine the mineral content of plants and their seeds. The concentrations of minerals in plants depend largely on plant genotype, soil environment, climate and stage …

The Effect Of Different Types Of Inoculants On The Characteristics Of Alfalfa, Ryegrass And Red Clover-Ryegrass-Timothy Silage, Vilma Vrotniakiene, Jonas Jatkauskas

IGC Proceedings (1977-2023)

Silage inoculants based on lactic acid bacteria (LAB) have demonstrated improvements in energy and nutrient recovery from grass and legume silages by lowering the pH and shifting the fermentation towards lactic acid production, by reducing storage losses due to spoilage and by increasing the aerobic stability during feed-out. There are different mixtures of strains currently on the market.

The present study was conducted according to the Deutsche Landwirtschafts-Gesellschaft Guidelines for the testing of silage additives in order to assess which mixtures of lactic acid bacteria would have a greater potential to improve fermentation profile of alfalfa, perennial ryegrass and red …

The Effect Of N-Fertilization Rate Or Inclusion Of Red Clover To Timothy Leys On Fatty Acid Composition In Dairy Cow Milk, Katarina Arvidsson, Anne-Maj Gustavsson, Veerle Fievez, Kjell Martinsson

IGC Proceedings (1977-2023)

There is growing awareness among consumers of the link between diet and health. Further, the public often associates dairy products with coronary heart disease, since most of the fatty acids (FA) in milk are saturated. Therefore, it would be desirable to improve the FA profile of milk, which might be achieved by using appropriate feeding regimes. N-fertilization has been shown to influence both total fatty acid (TFA) content and the FA composition in a wide variety of species (Arvidsson 2009). The aim of this experiment was to evaluate the effects of grass silages subjected to different N fertilisation regimes fed …

Abundance, Diversity And Importance Of Some Insects In Grasslands Of Indian Arid Zone, Nisha Patel

IGC Proceedings (1977-2023)

Grasslands in arid regions are home to a large number of species of insects, which are well adapted to living in this ecosystem. Insects constitute a major part of the total faunal biodiversity of these grasslands and provide valuable ecosystem services such as pollination, decomposition, nutrient recycling, being important links in the food chain, etc. Diversity of entomofauna is a good criteria for judging the health of a grassland. However this diversity has not yet been properly studied. In the present study, attempt was made to unravel the diversity of some groups of insects in the grasslands of Indian arid …

Influence Of Grass Species On The Mycotoxins Content, Jiri Skladanka, Daniela Knotova, Pavel Knot, Lucie Hodulikova, Jan Nedelnik, Iva Klusonova, Monika Novotna

IGC Proceedings (1977-2023)

Clean and healthy phytomass is a prerequisite for producing high-quality forage. Development of microscopic fungi may lead to the formation of mycotoxins (Opitz von Boberfeld et al., 2006), which are secondary metabolites produced especially by the fungi Aspergillus, Penicillium and Fusarium (Rodrigues and Naehrer, 2012). Mycotoxins are produced due to interactions and reactions of fungi to environmental conditions (Opitz von Boberfeld et al., 2002). Mycotoxins naturally have negative impacts upon livestock, causing alterations in hormonal functions, poor feed utilization, lower rates of body weight gain, and possibly death (Duarte et al., 2013).

Preventing the occurrence of mycotoxins …

Fungal Endophytes From The Aerial Tissues Of Important Tropical Forage Grasses Brachiaria Spp. In Kenya, Sita R. Ghimire, Joyce Njuguna, Leah Kago, Monday Ahonsi, Donald M. G. Njarui

IGC Proceedings (1977-2023)

Most, if not all plants in natural ecosystems are symbiotic with mycorrhizal fungi and/or fungal endophytes. This association between plant and fungi is believed to be over 400 million years old when plants first colonized the land (Redecker et al., 2000). These fungal symbionts play important roles on plant ecology, fitness, and evolution; shaping plant communities; and the community structure and diversity of associated organisms. The importance of fungal endophytes in cool season grasses production and effects of endophyte on the livestock health (Examples fescue toxicosis and ryegrass staggers) have been extensively investigated (Smith et al., 2009; di Menna …

Productivity Enhancement Of Livestock Through Promotion Of Fodder Cultivation In Jehanabad District, Shobha Rani, R. K. Sohane, Dinesh Mahto

IGC Proceedings (1977-2023)

Livestock production is the backbone of Indian agriculture and also plays a key role in providing employment especially in rural areas. In India, there is no practice of fodder production in rural areas and animals generally consume naturally grown grasses and shrubs which are of low quality in terms of protein and available energy, they are thus heavily dependent on seasonal variations and this results in fluctuation in fodder supply round the year affecting supply of milk round the year. For proper growth and development of the livestock, feed management is of great importance. In Jehanabad district, majority of the …

Biodiversity Conservation Of Indigenous Grasses To Meet Fodder Deficit In Odisha, Bijoy Kumar Sahoo, Binayak Dash

IGC Proceedings (1977-2023)

In Odisha, underfeeding of the livestock is the primary reason for decrease in production potential of the animals. On an average a desi cow of the state yields 0.214 kg of milk per day. The neglected calf management for generations also reduced the body weight of bullocks gradually. Low productivity of the indigenous and crossbred cows in the state is the absence of proper feeding material for them. The fodder availability in the state is ill matched to the livestock population. Out of the total greenfodder availability, contribution of cultivated green fodder is only 2.83% and majority (97.17 %) is …

Rhizobium-White Clover Symbiosis And Nitrogen Fixation Along A Soil Organic Carbon Gradient, Pieter A. Swanepoel, Philip R. Botha, Wayne F. Truter, A. Karen J. Surridge-Talbot, Alicia Van Der Merwe

IGC Proceedings (1977-2023)

Sustainable cultivated pasture production in the southern Cape region of South Africa requires management practices that will support soil quality (Swanepoel and Botha 2012). Soil organic carbon (C_org) sequestration is regarded as one of the most important ways to promote soil quality. Dairy farmers in the southern Cape attempt to increase C_org by following minimum-tillage practices. These irrigated dairy-pastures require high levels of nitrogen (N) to maintain highly productive pastures. Nitrogen fertilisers have be-come very expensive and severely strain profitability of these dairy-pastures. Forage legumes are frequently incorporated into the grass pastures to overcome economic and environmental …

Milk Production In Goats On Veld Hay Supplemented With Selected Legume Forages, Katsande Simbarashe, Joseph J. Baloyi, F. V. Nherera-Chokuda, N. T. Ngongoni

IGC Proceedings (1977-2023)

Alternative affordable sources of feed such as forage legumes that provide protein, vitamins and mineral elements, which are lacking in mature natural grassland pastures, especially during the dry season (Baloyi et al. 2008), can be an option. The high protein content of these legumes suggests that they have high potential for use as protein supplements in goat feeding. However, there is need for an in-depth study of the utilization of different legume forages for milk production in goats. Gusha et al. (2014) reported that supplementing with legume hays could improve poor quality roughage intake in goats. Snyman (2010) observed lower …
