Defoliation Impact On The Above And Belowground Productivity Of Festuca Arundinaceae Schreb, Hennie A. Snyman, P. J. Malan 2020 University of the Free State, South Africa

Defoliation Impact On The Above And Belowground Productivity Of Festuca Arundinaceae Schreb, Hennie A. Snyman, P. J. Malan

IGC Proceedings (1977-2023)

The main objective of pasture management is to maximize plant productivity and ensure sustainable animal performance, without inducing pasture deterioration. Many researchers indicated that plant survival and sustainable production is a function of seedbed preparation, irrigation and defoliation, with defoliation having the largest impact on plant persistence (Fulkerson and Donaghy, 2001). The net effect of defoliation (degree of intensity and frequency) can therefore either be beneficial or detrimental to survival and productivity of a pasture. The aim of this study was to quantify the impact of different intensities and frequencies of defoliation on above- and belowground phytomass production of the …

IGC Proceedings (1977-2023)

The per capita availability of land is consistently decreasing, while food and fodder demand is increasing. Indiscriminate and injudicious use of farm inputs for achieving potential yield of crops has not only enhanced the cost of cultivation but also threatened the environment and sustainability of the system. Combination of these factors and their interface are serious threats to agriculture and mankind. In rainfed condition of central India, fodder sorghum+cowpea –wheat is potential cropping system among farmers maintaining 2-4 livestock’s. The conventional tillage system which inverts and mixes the soil, introduces large amounts of oxygen into the soil and thus stimulates …

IGC Proceedings (1977-2023)

Pearl millet (Pennisetum glaucum L.) is important minor millets cultivated both for food and fodder. The dual purpose nature of pearl millet has recently identified due to its profused tillering, repeated harvesting and absence of anti nutritional factor. In fodder crops, the production potential can be manipulated by fertilizer management and time of harvest. In this regard, peal millet no exception, scientific study on cutting and nitrogen management on green fodder yield, quality and grain yield is meagre. Therefore, the present investigation was under taken to study the influence of cutting management and nitrogen levels on green forage and …

Deficiency of feed and fodder accounts for half of the total loss in dairy farming therefore, forages are called as backbone of livestock industry. The scarcity of green forages and grazing resources in the country has made the livestock to suffer continuously with malnutrition resulting in their production potentiality at sub-optimum level as compared to many developed nations (Anonymous, 2012). Arunachal Pradesh is well known for its ever green vegetation and biodiversity under hilly ecosystem. Though, it is situated at remotest part of country but possess huge scope of livestock farming. Namsai district of Arunachal Pradesh is a bordering district …

IGC Proceedings (1977-2023)

Dairy farming is an important and prevalent subsidiary occupation along with agriculture in the state of Punjab. But because of declining land holding, the pressure on land is so high that there is little scope of expanding the area under forage crops. Crop intensification either in space (intercropping) or in time (sequential cropping) or both is the feasible option left to the farmers for enhancing the fodder production. The green fodder is deficit by about 25% in the state and there is around 65,000 ha area under Agroforestry. There is a need to explore possibility of growing fodder crops under …

IGC Proceedings (1977-2023)

Brachiaria species play a strategic role in ruminant production systems in Brazil, covering an estimated pasture area of approximately 90 million hectares (Karia et al., 2006), however, these pastures are subject to different degrees of degradation due to inadequate management. In pasture management, field measurements such as canopy height, for example, are used by managers as a tool to establish parameters for the optimal point to cut the forage and for the post-grazing residue, in order to maximize production by harvesting at maximum of herbage mass accumulation, and to avoid problems associated to overgrazing, by setting ideal post-grazing height …

The distribution of grasslands and their floristic composition is related to the climate at the largest scale. Particular grassland is affected by bedrock, soil, water regime, altitude, nutrient status, local climate, disturbance etc (Gibson, 2009). Grasslands provide not only production functions but also large scale of ecosystem services such as nutrient cycling, sequestration of carbon dioxide, prevention of soil loss and many others. Ability of grasslands to afford both production and ecosystem functions depends among others on the floristic composition (Chytry, 2007). Semi-natural permanent meadows, as a result of the concurrence of many factors, represent a great reservoir of biodiversity. …

F. Clark, Ajantha Horadagoda, Helen Golder, Sergio C. Garcia, Kendra L. Kerrisk, Mohammed R. Islam

IGC Proceedings (1977-2023)

Pasture is typically offered to dairy cows in three allocations in pasture-based automatic milking systems (AMS). However, due to voluntary cow movement and distribution of milkings, some dairy cows access fresh pasture and other cows access depleted (stale) pasture. The first cows moving to an allocation of fresh pasture are offered ad-libitum, high quality pasture as opposed to cows arriving to the same allocation during the middle or end of the day accessing poorer quality, high fibre (neutral detergent fibre, NDF) pasture. In addition, grain-based concentrate (GBC) is allocated independently to this pasture state. The ability to increase feed …

Fungicide Sensitivity Of Sclerotinia Sclerotiorum Isolates Selected From Five Different States That Use Different Fungicide Treatments, Cristian Wulkop Gil

UCARE: Research Products

Sclerotinia sclerotiorum is a plant pathogenic fungus that causes a disease called white mold that can infect more than 450 plant species including soybeans, dry beans, green beans, canola, and sunflower. This pathogen is capable of up to $252M in losses every year (U.S. Canola Association, 2014). Fungicides are widely used in developed agricultural systems to control disease. However, resistance to the most effective fungicides has emerged and spread in pathogen populations and there have been multiple reports of S. sclerotiorum isolates becoming resistant to certain fungicides. Since different fields in different states use different fungicide treatments on plants and …

F. Clark, Mohammed R. Islam, Ajantha Horadagoda, Ravneet Kaur, Helen Golder, Sergio C. Garcia, Kendra L. Kerrisk

IGC Proceedings (1977-2023)

Automatic milking system (AMS) farms, rely upon voluntary cow traffic (the voluntary movement of cattle around a farm) for milk harvesting and feed consumption. Dairy cows on a pasture-based AMS farm typically move from depleted to fresh allocations of pasture in small groups, or individually, at differing times. The first cows moving to an allocation of fresh pasture get access to rapidly fermentable, ad libitum, high quality pasture in contrast to those cows accessing the same allocation towards the end of the access period. At the same time, grain-based concentrate (GBC) is allocated independent of the pasture state that …

The Effect Of Planting Date On The Dry Matter Production Of Italian And Westerwolds Ryegrass In The Southern Cape Of South Africa, Philip R. Botha, Janke Van Der Colf, Lethukuthula B. Zulu, Pieter A. Swanepoel

IGC Proceedings (1977-2023)

Perennial pasture species such as lucerne (Medicago sativa), kikuyu (Pennisetum clandestinum), perennial ryegrass (Lolium perenne) and perennial clovers (Trifolium spp.) make an important contribution to the fodder flow programmes for dairy production in the southern Cape. One of the main challenges when these species make up the primary pasture base within a pasture system is the mutually low growth rates during winter (Van Heerden et al., 1989; Swanepoel et al., 2014). In order to bridge pasture shortages during the critical winter months, producers establish annual Italian (Lolium multiflorum var. italicum …

IGC Proceedings (1977-2023)

Researchers are continuously searching for species that can improve the productivity and sustainability of pasture systems under adverse environmental conditions such as drought and extreme temperatures. Plant breeders have bred hybrids between ryegrass (Lolium spp.) and Fescue (Festuca spp.) in an attempt to combine the high forage quality of the former with the stress tolerance of the latter (Kopecky et al., 2008; Akgun et al., 2008). The resultant hybrids are commonly referred to as Festulolium spp. These species include Festulolium pabulare which is a cross between Tall Fescue (F. arundinacea) and Italian ryegrass …

IGC Proceedings (1977-2023)

The green fodder requirement and availability in India does not match and leaves a shortfall of about 63%. There is a little possibility of any tangible increase in fodder area due to competition from other economically competitive agricultural crops (Aulakh et al., 2012). Therefore, there is urgent need to maximize the tonnage and quality of fodder within the existing farming systems. Multicut nature of the crop ensures continuous supply of fodder. Kashmir valley possesses temperate type of climate, with snowfall and harsh conditions in the winter. Behaviour of crop under these conditions is entirely different from rest of country, …

Livestock rearing is an integral part of rural India. Livestock productivity in India is far below the desired level due to shortage in availability of green fodder for feeding the animals. The health and productivity of livestock mainly depends upon the availability of quality feed and fodders in requisite amount. The need for growing forage crops in unconventional lands is already been in discussion. In the lower Gangetic plains there farmers seldom go for fodder crops and only marginal lands are devoted for such crops. Low lying situations, marshy lands are quite frequent in the delta which may house fodders …

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 ( …

IGC Proceedings (1977-2023)

Agricultural waterways provide a buffer zone between crop fields and adjacent rivers or streams. Waterways are important resource for agriculture water management, water quality and biodiversity conservation. The total linear distance of waterway in Korea is about 180,000 km, and about 40% are concrete and about 60% are grassed waterways. At present, the percentage of concrete waterways is increasing because of their water management efficiency. Some argue that continued expansion of concrete waterways is not sustainable because it leads to potential-degradation of the earth's environment. This concern has led to renewed efforts to use grassed waterways as an alternative to …


Forage Options For Dairy Cows, Mohammed R. Islam, Sergio C. Garcia 2020 University of Sydney, Australia

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)

Automatic milking rotary (AMR) systems have the capacity to milk 800 cows. To maintain a pasture-based system whereby > 50% of the total diet is pasture (Garcia and Fulkerson, 2005), large herds milked by AMR will be required to walk significant distances. Walking distances of greater than 1-km are associated with an increased incidence of undesirably long milking intervals and reduced milk yield (Lyons N, unpubl. data). The aim of this study was to investigate the total land area required and associated walking distance for large automatic milking system (AMS) herds when incorporating complementary forage rotations (CFR; Garcia et al., …


A Historical Review Of Management Options Used Against The Stable Fly (Diptera: Muscidae), David F. Cook 2020 Department of Primary Industries and Regional Development, Western Australia

A Historical Review Of Management Options Used Against The Stable Fly (Diptera: Muscidae), David F. Cook

Animal production and livestock research articles

The stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae), remains a significant economic pest globally in situations where intensive animal production or horticultural production provide a suitable developmental medium. Stable flies have been recorded as pests of livestock and humans since the late 1800s to early 1900s. Over 100 years of research has seen numerous methodologies used to control this fly, in particular to protect cattle from flies to minimise production losses. Reduced milk production in dairy cows and decreased weight gain in beef cattle account for losses in the US alone of > $2000 million annually. Rural lifestyles and recreation are …
