Sustainable Quality Fodder Production Under Temperate Mountain Agriculture In Kashmir, Mushtaq Ahmad, Gul-Zaffar, Intikhab Aalum Jehangir, S. M. Razvi

IGC Proceedings (1977-2023)

Inadequate supply of quality feed and fodder is the primary cause of lower productivity of milch animals in India. Oats (Avena sativa L.) is an important fodder crop in J&K. Jammu and Kashmir state the fodder requirement is about 4.31 million tonnes against the available 3.26 million tonnes (Anonymous, 2008). Kashmir valley experiences a long lean period of winter, resulting in scarcity of green and quality fodder which results in drastic decrease in milk production. Therefore, to meet the need of animal products, there is a great importance of fodder cultivation to compensate fodder scarcity during lean period ( …

Forage Options For Dairy Cows, Mohammed R. Islam, Sergio C. Garcia

IGC Proceedings (1977-2023)

To remain competitive internationally, the Australian dairy industry will need to increase milk production per unit of land by producing and utilising more from home-grown feed. In the context of decreasing land availability but increasing feed cost per unit of land, increasing production and utilisation of home-grown feed is crucial to increase milk production in pasture-based dairy farms (Fariña et al., 2011). Pure pasture-based systems can achieve a maximum of ~20 t dry matter (DM)/ha/yr, although in practice top commercial farmers hardly exceed 15-16 t DM/ha. A strategy to increase productivity of forages is to select adequate combinations of …

IGC Proceedings (1977-2023)

The agriculture of seventies in the hot arid zone of India (western Rajasthan) was chiefly the subsistence farming involving rearing of livestock in association with rainfed cultivation of guar, moth and pearl millet. Pasturelands dominate among different land use systems and provide main support to the huge livestock population of the region (Kar et al., 2009). With the advent of Indira Gandhi Canal and commencement of tube-well technology in 1985, livestock based economy saw a change in the land use and large tracts of sewan grass (Lasiurus sindicus) came under the plough. Further, in arid zone as …

Identification Of Niches For Integration Of Brachiaria Grasses In Smallholder Mixed Crop-Livestock Farming Systems In Kenya, Donald M. G. Njarui, Elias M. Gichangi, Mwangi Gatheru, Michael N. Njunie, Elkana Nyambati, Keziah W. Ndungu, Joseph G. Mureithi, Sita R. Ghimire

IGC Proceedings (1977-2023)

Inadequate quantity and quality of feed is the major constraint to livestock productivity in Kenya. Low rainfall, lack of adapted forages and poor management of sown forages are major factors that affect feed resources production. In most of the farming systems, forages are relegated to the less fertile and degraded soils resulting into poor growth. As a result the growth is poor resulting in deficient in minerals content, low crude protein (CP) and energy. The situation in exacerbated by climate variability and frequent drought. On the other hand, feed resources derived from crop residues, particularly cereals are of poor quality …

Evaluation Of Baby Corn Hybrids On Varying Plant Population And Nutrient Levels, M. Hargilas

IGC Proceedings (1977-2023)

India is a largest producer country of the milk with largest livestock population in the world. Main herds of cow/ buffalo exist in surrounding areas of town and cities for supply of milk. The animal productivity directly depends on the availability of good quality green fodder. At present, the country faces a net deficit of 35.6% of green fodder, 26% of drycrop residues and 41% of concentrate feed ingredients (www.dare.nic.in/nodel/87). To overcome this problem, there is a need to shift from sole food and fodder crops to the dual or multipurpose food cum fodder crops. Under this situation, baby corn …

Spider Fauna (Araneae: Araneomorphae) In Natural Grasslands Of Uruguay With Different Livestock Management, Álvaro Laborda, Rafael A. Tosi-Germán, Sebastián Donate, Oscar Blumetto

IGC Proceedings (1977-2023)

In Uruguay natural grasslands sustain cattle ranching and are the country’s main renewable resource. This ecosystem not only serves a productive function, but also functions in geophysical processes of soils and sustaining the nation’s biodiversity through complex trophic webs (Berretta 2009). Increased pressure from human activities that exploit natural resources makes it necessary to possess tools for detecting disturbances in ecosystems and assessing their conservation status. Identifying indicator taxa is essential for evaluating the degree of impact on natural grasslands and for applying this in the development of management plans for this habitat type (Avalos et al. 2007; Cardoso …

Yak Rearing On High Altitude Pastures Of Northeastern Himalaya Of India: Their Utilization Strategies And Rejuvenation, Vijay Paul, Sanjit Maiti, G. Krishnan, D. Medhi, S. M. Deb

IGC Proceedings (1977-2023)

Yak rearing on alpine pastures is the main occupation of the highland pastoral nomads (Brokpa and Dokpas) of north-east (NE) India. These pastoral nomads living in the remote mountains solely rely on high altitude pastures for their nutritional and livelihood security because of virtual existence of agricultural activities in this area. They rear yaks under transhumance and utilize various pastures while migrating from low land winter pastures to high altitude alpine pastures during summer. Therefore, the temperate and alpine pastures are the major feed resources for the yaks. The indiscriminate use of pastures and impending climate change results …

Daugherty Water for Food Global Institute: Faculty Publications

Human consumption of freshwater is now approaching or surpassing the rate at which water sources are being naturally replenished in many regions, creating water shortage risks for people and ecosystems. Here we assess the impact of human water uses and their connection to water scarcity and ecological damage across the United States, identify primary causes of river dewatering and explore ways to ameliorate them. We find irrigation of cattle-feed crops to be the greatest consumer of river water in the western United States, implicating beef and dairy consumption as the leading driver of water shortages and fish imperilment in the …

Land Surface Phenology In The Highland Pastures Of Montane Central Asia: Interactions With Snow Cover Seasonality And Terrain Characteristics, Monika A. Tomaszewska, Lan H. Nguyen, Geoffrey Henebry

NASA Land-Cover Land-Use Change Data Sets

Many studies have shown that high elevation environments are among very sensitive to climatic changes and where impacts are exacerbated. Across Central Asia, which is especially vulnerable to climate change due to aridity, the ability of global climate projections to capture the complex dynamics of mountainous environments is particularly limited. Over montane Central Asia, agropastoralism constitutes a major portion of the rural economy. Extensive herbaceous vegetation forms the basis of rural economies in Kyrgyzstan. Here we focus on snow cover seasonality and the effects of terrain on phenology in highland pastures using remote sensing data for 2001–2017. First, we describe …

Integrating The Bioenergy Production With Biodiversity Conservation On Semi-Natural And Riparian Grasslands, Tomasz Goliński, Piotr Goliński

IGC Proceedings (1977-2023)

Semi-natural grasslands in Poland have been identified as having extraordinary biodiversity value. In the past, the species richness of these semi-natural landscapes has been managed through grazing. However, livestock numbers are now in decline, many grasslands are abandoned and consequently the diversity of these landscapes is under threat. In order to prevent these habitats from turning to scrublands, these areas have to be extensively harvested. Regulations dictate a late harvest time to allow reproduction of the flora and fauna. Many of semi-natural and riparian grasslands are protected under the European Habitats Directive and their management is financially supported by introduction …

Integration Of Biodiversity And Agricultural Production Across Australian Temperate Grasslands, Kerry L. Bridle, Jim Crosthwaite, Louise Gilfedder

IGC Proceedings (1977-2023)

The transformation of Australian agriculture over the 20th Century saw the conversion of native pastures to improved pastures, largely through the application of artificial fertilisers. During this time biodiversity conservation was largely confined to iconic scenic reserves on public land. Today, nationally endangered temperate native grassland communities are largely confined to private land. The development of the Landcare Movement in the 1980s highlighted the role that agricultural land managers and agricultural landscapes play in maintaining biodiversity across the continent. Research into on-farm conservation was soon being funded by governments at state and commonwealth levels, as well as industry bodies. These …

IGC Proceedings (1977-2023)

North Eastern states of India particularly in Manipur livestock rearing were being considered as one of the important homestead activities in the farm household. In the rural household economy, livestock is considered as an inseparable component in the whole farm business, as the production of milk and meat as well as manure, draught and transportation depends on it. It provides nutritional security to farm family and stabilizes farm income too.

As a major source of animal feeds in Manipur, fodder trees and shrubs are highly valued by farmers. They have deep root systems enabling the extraction of water and nutrients …

Framing Effect And Pastoralist Decision Making Behavior Regarding Lambing Time-An Analysis From Inner Mongolia, China, Yanting Yin, Xiangyang Hou, Xiangjun Yun, Xiliang Li

IGC Proceedings (1977-2023)

Grassland is the largest terrestrial ecosystem in China. However, it is seriously degraded. Lower stocking rates have been necessary for rehabilitating the degraded grassland. In order to rehabilitate the grassland the government proposed the “balancing animals and grass” policy. However, it has been resisted by pastoralists. (Brown et al., 2009). The reasons for the policy’s failure have been widely discussed. To date, there has been a lack of discussion on explicitly addressing the role of pastoralist behavior regarding stock numbers and lambing time. The pastoralists continue to maintain their traditional stocking rate, and take short-term adaptive measures to balance their …

Pasture Management For Sustainable Forage Production, Pijush Kanti Mukherjee, Putan Singh, S. S. Singh

IGC Proceedings (1977-2023)

In the livestock management grazing was the major feed resources in the past and even today a significant portion of livestock is being sustained on grazing resources from pastures and other grazing lands like forest, fallow lands, cultivable waste lands etc.

During the last few decades ever increasing livestock population has created enormous grazing pressure on pasture resources leading to deterioration and destruction of pastures. This has led to the urgent need of improvement of pastures as well as judicious implementation of grazing management practices. There has been certain constraints on pasture development which include fragmentation and degradation of …

Herders’ Forage-Livestock Decision Behavior In Northern Grassland Regions Of China, Xiangyang Hou, Yanting Yin, Tingting Wang

IGC Proceedings (1977-2023)

China has approximately 393 million hectares of grasslands, accounting for 41.7% of the national land area. However, 90% of useable grasslands are degraded because of human and natural reasons. Overgrazing was the dominant factor affecting grassland condition. In order to control the grassland degradation problems, the government has proposed the „forage-livestock balance‟ policy in 2002. A series of ecological policies were (Hou et al., 2013) and outcomes have been described as a “partial improvement amidst overall deterioration”. Reasons for apparent failure of the policy have been the subject of much discussion over the years. However, there has been a …

Improving A Transhumance Livestock System Of India With Modern Technologies, Mounir Louhaichi, Arun Kumar Misra, Khem Chand, Mahesh Kumar Gaur, Douglas E. Johnson

IGC Proceedings (1977-2023)

Traditional livestock rearing systems in grasslands evolved in response to social, climatic, vegetative and technological conditions that existed scores, hundreds, or in some cases up to a thousand of years ago. Many of these systems involve vertical transhumance where flocks and herds are moved up elevation gradients for summer pasturage or horizontal transhumance in which livestock migrate across greater distances in response to regional rainfall patterns and the resulting availability of forage. In spite of the relatively low earnings of individual herders, these pastoral systems can contribute substantially to the national economies, while providing sustenance and food security to significant …
