IGC Proceedings (1997-2023)
The alfalfa weevil Hypera postica (Gyllenhal) (Coleoptera: Curculionidae) is one of the most destructive insect pests of alfalfa herbage in North America. Palearctic in origin, the weevil was first found in North America near Salt Lake City, Utah, in 1902 (Titus 1911), with the first Canadian record in southeast Alberta and southwest Saskatchewan in 1954 (Hobbs et al. 1959; Beirne 1971). Alfalfa weevil became an economic pest on the Canadian prairies only in the area of first location, and its distribution remained below the 51st parallel North latitude for about 40 years. In the mid-1990s, however, the weevil expanded …

Environment Impact Of Moxidectin In Sheep Faeces Upon Dung Diptera In South Of Brazil, Alda L. G. Monteiro, Susana Gilaverte, Maria Angela M. Fernandes, Alessandre P. Colavite, Paulo Guimarães, Mylena T. P. Peres, Cláudio J. A. Da Silva
IGC Proceedings (1997-2023)
Dung Diptera can be beneficial to the environment because the adults feed on, deposit eggs in, and the larval nutrition depends on the feaces of animals which significantly im-proves nutrient cycling. However, anthelmintics which are used to control internal parasites have long persistence with a long half-life in faeces. This is harmful to the coprofauna and may adversely affect the diversity of this environmen-tal system. In this study we evaluated the toxicity of moxidectin anthelmintic on the dung Diptera population in pastures of South of Brazil.

Soil Fertility Under Grassland Compared To Other Land Uses In Acid Soil Of Himachal Pradesh, India, Sharmistha Pal, Pankaj Panwar, D. R. Bhardwaj
IGC Proceedings (1997-2023)
In the last decades severe changes in land use occurred in tropical countries, due to increasing population and their demand for food resources. Forest land is rapidly converted into agriculture or pastureland which may cause significant changes in soil fertility. Land-use exerts significant effect on nutrient availability and may also influence secondary succession and biomass production (Lu et al., 2002). Nutrient cycling in agroforestry is in between natural forest ecosystems of the tropics and most of the agricultural systems with are ‘‘leaky’’ having higher nutrient losses. Research indicated that decline of soil organic matter may occur due to conversion …

Mix Cropping Of Smooth Vetch And Barley Under Cold Rainfed Conditions, Mahmoud Pouryousef, Khoshnood Alizadeh
IGC Proceedings (1997-2023)
Drylands are mainly used for wheat and food legumes production and there is increasing demand to forage crops in these areas. About 2-3 million hectares of arable lands across Iran are left as fallow every year (Alizadeh, 2010) which could be used to suitable forage crops. Considerable variation has been reported in herbage and grain yields of improved vetches (Vicia spp.) under Iranian rainfed conditions. Introduction of annual feed legumes in dryland cropping systems that are dominated by cereals would reduce pest and disease risk and increase sustainable productivity. However, vetch species as monocultures produce low forage yield under …

Quality Of Grass Fodder Cowpea Mixtures As Influenced By Row Ratio, S. Lakshmi, M. R. Anita
IGC Proceedings (1997-2023)
A serious drawback of sustainable livestock production system in Kerala is the inadequate seasonal distribution of fodder production. The quantity and quality of herbage available in the lean dry months from January to May is very low. Therefore it is imperative to develop a fodder production system that increases the availability and improves the quality of herbage in the dry summer months. Intensive fodder production systems based on grasses are increasingly becoming important to the dairy farmers of Kerala. Development of compatible persistent grass legume mixtures could alleviate acute seasonal livestock feed deficiency in dry seasons (Njarui et al., 2004). …

Ethical Use Of Cereal Legume Intercrop Forages For Feeding Of Sheep And Pasture Development, S. B. Maity, K. K. Singh, G. Prabhu, N. Das
IGC Proceedings (1997-2023)
Cereal forages are important in the feeding of livestock for their high energy and dry matter content. However, they are low in protein content and inferior in other nutritional quality than the legume forages. Ruminants required protein as well as energy to maintain their production. Supplementation of protein through concentrates is cost effective in livestock production. Besides, ruminant is unique in having the potential for cycling forage materials, poor quality protein and non protein nitrogen sources into human food supply as meat and milk (Eskandary et al., 2009). Thus, management of forages for livestock feeding either in feedlot or in …

Forage Legumes Intercropping And Nitrogen Management Effects On Performance Of Guinea Grass (Panicum Maximum) Varieties In Bundelkhand Region Of India, Mukesh Choudhary, G. Prabhu
IGC Proceedings (1997-2023)
Guinea grass (Panicum maximum Jacq.) is one of the important forage grass of the tropics with good yield potential, palatability, persistence and quality fodder (Sukhchain, 2010). The low crude protein productivity of guinea grass can be enhanced through its intercropping with forage legumes to sustain ruminant animals throughout the year. The intercropping of legumes with guinea grass will also optimize forage production per unit area, especially during rabi season. Further, its productivity can also be increased through N management as it is heavy feeder due to perennial and multi-cut nature.

IGC Proceedings (1997-2023)
Pig slurry is the most important organic resource in Korea, as estimated to be more than 15% of recycled animal manure. The use of pig slurry as an alternative organic fertilizer is the most viable recycling option as it is produced in large amount on pig farms that has usually less or not surface for cultivation of forage crops in Korea. Perennial grasses in grassland system regrow successively after harvests by cutting or grazing. The regrowth yield at each harvest would be a crucial determinant for the productivity of sward. During vegetative regrowth, soil mineral N and N reserves meet …

IGC Proceedings (1997-2023)
Dairy farming is a major branch of agriculture in Latvia. Therefore, providing livestock with high quality grass forage over the whole grazing season is of great importance. However, the cost of obtaining high quality grass forage should not be too high. Perennial forage legume-grass stands meets the required demands best of all. Inclusion of white clover in legume-grass stands contributes to the production of high quality herbage swards (Frame and Newbould, 1986; Laidlaw et al., 1995; Orr et al., 1990; Van Bockstaele, 1985). The nutritive value of white clover depends on the favorable leaf: stem ratio in total …

Yield And N Recovery By Grass Species In Response To Long Term Applications Of Manure And Mineral Fertilizer In A Cool Maritime Climate, Shabtai Bittman, Derek Hunt
IGC Proceedings (1997-2023)
Liquid manure is an important source of nutrients on many modern dairy farms. Nitrogen (N) use efficiency of slurry is usually less than chemical fertilizer, but the difference is less when tested in trials lasting at least 7 years than in short term trials (Schröder et al., 2007). The efficiency of slurry manure N can be improved by minimizing loss of ammonia after application using low emission applicators. In grass stands where injection is impractical, mitigation methods often involve spreading the slurry in narrow bands directly on the soil surface. Losses of N as ammonia, nitrous oxide and leaching have …

Presence Of Pesticide Residue In Feeds–An Assessment, Arpana Singh, S. K. Nag
IGC Proceedings (1997-2023)
The presence of varying types of toxic substances in feed is undesirable as it acts as the main source of entry of these chemicals into the animal body, redistribution and deposition in different tissues for a long time depending on the nature of the toxicants. Feed safety is equally important as food safety as both are directly linked when production of food of animal origin is concerned. Presence of pesticide residues are often reported in different feed resources (Kang et al., 2002; Sharma et al., 2005; Nag, 2006). These residues may ultimately contaminate the food chain and accumulate in human …
