A Study Of Molecular Interface Of Grass-Herbivory Interaction In Grass, Xiaoxia Li, Gongshe Liu, Shuangyan Chen, Zhipeng Liu, Liqin Cheng

IGC Proceedings (1977-2023)

Grass-herbivore interaction is a complex process that involves wounding effects caused by herbivore feeding, defoliation effects due to leaf-surface loss during grazing, and the deposition of herbivore saliva onto the surface of plants (Chen et al., 2009). Wounding can stimulate plant growth but clearly differs from grazing (Mattiacci et al., 1995). Defoliation affects root development in grasses and alters the carbohydrate-metabolism pathway in rice. Saliva has been found to stimulate plant growth, enhance tiller and increase biomass. However, little is known about the molecular mechanisms of plant responses to grazing in molecular level. In our previous transcriptome studies, many …

Pasture Management To Improve Dry Matter Intake, Marcus F. Rose, Earl Creech, Blair L. Waldron, S. Clay Isom, Michael Peel, Kara Thornton-Kurth, Jacob Hadfield, Kerry A. Rood

All Current Publications

Agricultural producers are constantly looking for ways to maximize returns while reducing input costs. On dairy operations, a move from confinement feeding to pasture grazing offers the potential to reduce costs associated with harvest and storage of feed. In such a transition, producers sometimes report a decline in milk production and growth of livestock—both of which can strongly correlate to dry matter intake. Fortunately, dry matter intake is something that can be influenced by management practices. In this publication, we discuss the pasture management practices to improve dry matter intake.

Vegetation Dynamics In Relation To Land Use Within The High Altitude Alpine Grasslands Of Lesotho, Southern Africa, Nico Smit, G. Janse Van Rensburg

IGC Proceedings (1977-2023)

The Kingdom of Lesotho is characterized by its unique geographical feature of being dominated by rugged mountainous terrain. It is also the only true alpine region in southern Africa that supports high plant species diversity. Large areas suffer from overgrazing and erosion, as well as over exploitation of its natural resources. The livestock industry in Lesotho has long been a vital component of the economic and social structure of the country and the alpine region is considered as an important grazing resource by local Basotho herdsmen. Consequently, a study was conducted with the two objectives: to determine the phytomass, grazing …

Impact Of Development Projects On Grazing Resources Of Odisha, Binayak Dash, Bijoy Kumar Sahoo

IGC Proceedings (1977-2023)

Odisha, a state of modern India lies in the sub-tropical belt in eastern part of the country. It is the 10th largest state of India in terms of geographical area (15.57 million hectares). Out of the total geographical area, 37.33% constitute forest land and 39.69% cultivated land. These 6.180 million hectares of cultivated land is the source of food of almost 41.9 million human beings (Census, 2011) and 20.72 million livestock (Livestock Census 2012) of the state. Thus there is scarcity of land in the state. Majority of the farmers in the state are marginal and small (86.16%) owning less …

Factors Affecting Rangeland Utilization By Ranchers In The Golestan Rangelands, Iran, Reza Tamartash, Mohammadreza Tatian, Maedeh Yousefian, Fatemeh Montazeri, Hamid Mostafalou

IGC Proceedings (1977-2023)

In Iran, rangelands produce most of the forage resources for livestock. There are various types of traditional grazing systems for the utilization of rangelands, including the consultative, collective and operational multiplayer systems. In the consultative type, certain people are selected by the ranchers and they determine the utilization method and manage grazing. In the collective system, all ranchers use rangeland in common. In the operational multiplayer system, rangelands are used in common but the ranchers share rangelands by rancher-rancher negotiation. This research was undertaken to investigate the human factors as rancher's effect on rangeland utilization in different systems above mentioned.

Impact Of Grazing On Soil Seed Bank Replenishment Under The Mediterranean Climate Of Northern Syria, Abdoul Aziz Niane, P. C. Struik, Murari Singh, Zewdie Bishaw

IGC Proceedings (1977-2023)

Rangelands represent 70% of the semi-arid and arid Mediterranean land mass. It is a habitat for millions of people whose livelihood depends on animal husbandry. The revolutionary developments in the animal husbandry and veterinary medicines resulted in exponential increases in livestock and human populations living on and from dry lands. To respond to population growth, expansion on urbanization, transportation and road networks, land reform and rural development policies forced nomads to adopt sedentary lifestyles. The demographic changes coupled with national and international border crossing restrictions escalated opportunistic cultivation, and excessive exploitation of the scarce and slowly renewable vegetation cover of …

On-Offer And Residual Forage In A Massai-Leucaena Pasture At Different Leucaena Density, Enrique Cortés-Díaz, Juan Peñate Arcos, José L. Zaragoza-Ramírez, Pedro A. Martínez-Hernández

IGC Proceedings (1977-2023)

Mexican livestock producers in tropical areas are increasingly interested on the establishment of silvopastoral systems based on Leucaena (Leucaena leucocephala (Lam.) de Wit) and different tropical grasses as the Massai grass (Panicum maximum cv Massai); among questions raised on this is the importance of Leucaena density in relation to forage available. Then the objective of the study was to determine total and by species on-offer and residual forage in a grazed MassaiLeucaena pasture with different Leucaena density.

Improved Modelling Of Lucerne (Medicago Sativa L.) Production For Grazing Livestock, Andrew Smith

IGC Proceedings (1977-2023)

Lucerne (or alfalfa; Medicago sativa L.)-based pastures play an important role in livestock and mixed farms (croplivestock) in Australia. If lucerne is to be more widely adopted, it will be important that landholders are able to plan to maximize its benefits to their livestock enterprises (usually as a part of a diverse feed base), as well as assess the benefits and minimizing the costs of lucerne phases to subsequent crops. However, the ability to accurately model lucerne plant physiology across the full spectrum of environments, genotypes and cultivars remains elusive. This study aimed to review and revise the description of …

Use Of Native Grassland In Small-Scale Dairy Systems In The Highlands Of Central Mexico. A Case Study, P. A. Sainz-Sanchez, Carloss Manuel Arriaga-Jordan, D. Heredia Nava, C. G. Martinez-Garcia, F. Vicente, L. R. Garcia-Winder, A. Martinez-Fernandez

IGC Proceedings (1977-2023)

Small-scale dairy systems in Mexico comprise 78% of specialized dairy farms and provide 37% of national production. They are small farms with herds 3-35 cows plus replacements, and rely on family labour (Posadas-Domínguez et al., 2014).

In the highlands, many farms have native grasslands, grazed during the rainy season, and supplemented with other feeds as maize straw, maize grain and maize ears. Native grasslands have not been studied in this context. This is a case study on the use of native grassland in a small-scale dairy farm. The objective was to determine how native grasslands are integrated in feeding …

Spring Meadow Management Practices: What’S A Rancher To Do?, Tara M. Harms, Jerry D. Volesky, Mitchell B. Stephenson

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Subirrigated meadows are a valuable forage resource to ranching operations in the Nebraska Sandhills, being used for both hay production and livestock grazing.

The water table of these meadows is within one meter of the soil surface during the growing season.

In some years, wet conditions hinder meadow utilization, resulting in a buildup of standing dead and litter plant material which can lower forage production.

Investigate if burning and mowing are effective strategies to remove dead plant material from meadows • Determine if burning or mowing interact with grazing to influence end of season forage production

Burning or mowing effectively …

Plant And Animal Responses To Different Grazing Regimes On A Meadow Steppe In Northeast China, Deli Wang, Zhiming Yang, Ling Wang

IGC Proceedings (1977-2023)

Grazing by domestic herbivores is often considered to be an essential factor governing grassland vegetation and animal production (Hodgson and Illius 1996). During recent decades, there is increasing interest as a fundamental interaction between plant-animal interface, especially for the simultaneous or interactive responses of plants and animals to grassland grazing regimes (Liu et al., 2015), which benefits on improving the efficiency of grazing or grassland resource management. To achieve sustainable animal productivity and maintain the stability of grasslands, farmers or stakeholders need to employ optimal grazing strategies or regimes based on practical grassland vegetation and environments. Unfortunately, up to date …
