Comparison Of Two Systems Of Pasture Allocation On Milking Intervals And Total Daily Milk Yield Of Dairy Cows In A Pasture-Based Automatic Milking System, Nicolas A. Lyons, Kendra L. Kerrisk, Sergio C. Garcia

IGC Proceedings (1977-2023)

In pasture-based automatic milking systems (AMS), cows usually have a lower milking frequency (MF, the number of milking events in any 24 h period) than those reported in indoor housing systems (García and Fulkerson 2005). Moreover, milking intervals (MI, the interval between consecutive milking events, measured at every milking session in hours since the previous milking event) are higher, with up to 30% of milking events occurring with intervals above 16 h in grazing systems (NA Lyons unpublished data). Milking events occurring with long intervals have a negative effect on milk yield (Schmidt 1960) and udder health (Hammer et al. …

Animal Behaviour And Pasture Depletion In A Pasture-Based Automatic Milking System, Nicolas A. Lyons, Kendra L. Kerrisk, Sergio C. Garcia

IGC Proceedings (1977-2023)

In an automatic milking system (AMS) feed is used as an incentive to encourage voluntary and distributed cow traffic to the milking unit (Prescott et al. 1998). Therefore the timing, placement and size of feed allocations need to be managed in order to achieve targeted milking events per day.

Behavioural studies allow the construction of time budgets (Gibb et al. 1998), and aid understanding of how cows modify their behaviour under different management regimes (Johansson et al. 1999). To date there are no published reports on how different location of feed incentives affect cows’ behaviour upon arrival at …

Grazing Behaviour Of Dairy Cows When Grazing Forage Rape In A Pasture-Based Automatic Milking System, Ajantha Horadagoda, Cameron E. F. Clark, Kendra L. Kerrisk, Mohammed R. Islam, Ravneet Kaur, Sergio C. Garcia

IGC Proceedings (1977-2023)

Forage rape (Brassica napus L.) is a high producing, high nutritive value forage that has been successfully introduced as a grazable forage in conventional, intensified pasture-based dairy systems to fill autumn-winter feed gaps (Garcia et al. 2008). However, incorporation of forage rape as a grazing forage option for automatic milking systems (AMS), in which cows enter and exit grazing areas voluntarily, has not been investigated yet. We conducted an observational study to investigate the suitability of using forage rape in AMS and gain understanding of cow’s foraging behaviour when grazing this forage. The outcomes of this piece of …

Effect Of Sugar Promoters On Biomass Yield And Sugar Content Of Napier Bajra Hybrids, Rajiv K. Agrawal, G. Prabhu, K. K. Singh, Sultan Singh, M. M. Das, Satendra Kumar

IGC Proceedings (1977-2023)

In India deficiency of green fodder is estimated to the tune of 35.7% and this difference is likely to increase in coming period due to possible decrease in acreage under fodder crops as the cultivated land is being utilized for urbanization and other industrial uses. In tropical countries like India, crop residues from cultivated crops and grasses (mainly monsoon grasses) constitute the basal diet of livestock. But the nutritive value of these grasses is low (protein and digestibility) than the fodder crops and even in green stage is able only to meet the maintenance requirement of animals. A conservative estimate …

Semi-Mechanized Harvesting Solutions For Cultivated Fodder Crops, Chandra Shekhar Sahay, P. K. Pathak, B. Narsimlu, C. R. Mehta

IGC Proceedings (1977-2023)

In case of harvesting and threshing, the level of mechanization in India is 60-70 per cent for wheat and rice and less than five per cent for other crops (Mehta et al., 2014) that include fodder also. Herrmann et al.(2011) established that overall area capacities of machine decreased the by 4-24 per cent on taking finer chopping length of 4-6 mm compared to common chopping length of 8-10 mm in the ensiling chain of maize - establishing that finer work in ensiling commands less capacities and higher input costs. Since there is a strong correlation between effective field …

Introduction Of Grass Pea As A Suitable Summer Crop After Barley Harvesting In The Semi-Arid Areas, Khoshnood, Mahmoud Pooryousef, Shiv Kumar

IGC Proceedings (1977-2023)

Forage production during summer season is a big challenge in the semi-arid dry areas. Forage crops become more important with increasing demand for meat and milk in the developing countries (Delgado, 2003). There are suitable opportunities to increase forage production without any decrease in cultivated areas under major cereal crops. Grass pea (Lathyrus sativus L.) and other neglected crops offer viable options for forage production. Forage crops cannot be recommended for cultivation at the expense of cereal crops which are defined as strategic crops for food security in most countries including Iran (Anonymous, 2010). Therefore, it is necessary to …

Influence Of Cutting Interval On Yield And Quality Of Purple Guinea Grass (Panicum Maximum Td58) Under Irrigation, Witthaya Sumamal, Pornchai Lowilai

IGC Proceedings (1977-2023)

Most of dairy farmers in the northeast of Thailand are smallholders. They have limited pasture area led to lack of good quality roughage throughout the year, especially during the dry season. Farmers usually fed their cattle with agricultural by products, which have low quality and supplemented with commercial concentrate feed. It leads to high milk production cost and more problems of cattle performance. It is necessary to develop and improve the feed quality and quantity, especially pasture, the cheapest and major source of cattle feed. Due to the limited pasture area, intensive pasture system is recommended. They need a suitable …

Influence Of Foliar Sprays Of Thiourea And Sulfuric Acid Against Frost Injury In Berseem, Balwinder Kumar, R. S. Sarlach

IGC Proceedings (1977-2023)

Berseem (Trifolium alexandrinum L.) is an important winter season fodder crop which occupies 2 million ha area in India (Kumar et al., 2013). Berseem is generally grown as pure stands or in mixture with annual grass species for feeding to the livestock. During severe winter month periods from December to February, berseem growth is slow due to low minimum air temperature or cold wave or frost occurrence which affects fodder availability to the livestock. To increase growth of berseem either in pure stand or in mixture, farmers generally use excessive urea which not only affects nodule development in …

Integrated Farming Systems In The Frame Work Of Bio-Economic Modelling For Sustainable Development Of Small And Marginal Farmers Under Changing Climatic Scenario, U. K. Behera

IGC Proceedings (1977-2023)

In order to meet the multiple objectives of poverty reduction, food security, competitiveness and sustainability several researchers have recommended to adopt integrated farming systems (IFS). IFS is an approach in which different landbased enterprises are integrated within the bio-physical and socio-economic situations taking farmers preference and goal in to consideration. This is a multi-disciplinary approach and very effective for solving the problems of small and marginal farmers (Gangwar, 1993). Under the gradual shrinking of land holding in India and other developing countries, it is necessary to go for IFS to make farming more profitable and sustainable. In agricultural research and …

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)

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 …

Effect Of Fertilization Level And Cutting Pattern On Species Diversity Of Meadow Stand, Pavel Knot, Josef Raus, Michal Kvasnovský, Jiri Skladanka, Frantisek Hrabe

IGC Proceedings (1977-2023)

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. …

Increasing Feed Conversion Efficiency In Automatic Milking Systems: The Impact Of Grain-Based Concentrate Allocation And Kikuyu (Pennisetum Clandestinum) Pasture State On Milk Production, Ravneet Kaur, Cameron E. 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 …

Increasing Feed Conversion Efficiency In Automatic Milking Systems: The Impact Of Grain-Based Concentrate Allocation And Kikuyu (Pennisetum Clandestinum) Pasture State On Kikuyu Pasture Digestibility, Cameron E. 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 …
