Grassland Management In Wildlife Protected Areas (Pa's) In India, R. K. Pandey

IGC Proceedings (1993-2023)

Ecological status of Indian grasslands had been a subject of conflicting opinion in the past. Existing grasslands are anthropogenic in origin except, Himalayan meadows in high altitudes. Extensive clearing of the forests for human settlements, agricultural cultivation and domestication of animals in the past have been resulted into opening of pockets/grasslands amidst the forest areas. Such tame grasslands are categorized as succession or rotational grasslands. There are four categories of PAs viz., National parks, wildlife sanctuaries, conservation reserves and community reserves. Thus, 683 PAs (102 national parks, 551 wildlife sanctuaries, 47 conservation reserves and 04 community reserves) spread over …

IGC Proceedings (1993-2023)

Ruminant livestock are essential to the livelihoods of smallholder farmers in many developing countries. Livestock production on these farms is characterised by low milk production, low live weight gain and poor reproductive performance because of poor nutrition. Access to high quality forage has been identified as key to improving livestock health and productivity. Conservation of surplus forage as hay or silage provides the opportunity to ensure livestock have access to high quality forage year-round. This paper reports on forage conservation in select countries in Asia and Africa.

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 (1993-2023)

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event) are higher, with up to 30% of milking events occurring with intervals above 16 h in grazing systems (NA Lyons unpublished data).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 (1993-2023)

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 …

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

IGC Proceedings (1993-2023)

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 (1993-2023)

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 …
