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event) are higher, with up to 30% of milking events occurring with intervals above 16 h in grazing systems (NA Lyons unpublished data).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

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

IGC Proceedings (1993-2023)

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 …
