We propose a metric for the analysis of the dependencies in a network of dynamic systems. We formally define the dependency and show that the derived metric approximates the 'strength' of the dependency. This metric is particularly suited for the analysis of the critical infrastructures (CI). It is vital for the CI networks to characterise and measure dependencies in order to be aware of destructive phenomena such as inter and infra CI cascading failures. The proposed metric is algorithmically simple, online data-driven and does not need the knowledge of the node dynamics.
Bull Calves Need Care Too
By far, most bull calves will never become a lasting benefit to a dairy herd, and as such may not always receive the same level of care that heifer calves do. Harmonizing your calf rearing programs will yield positive results for all calves and your bottom line. All calves require excellent care, especially in the first few days of life. Without adequate, timely colostrum and proper milk replacer/milk intake, heifer calves will produce less milk later in life, not to mention reduced likelihood of entering the...
High Fat Feeding - Case Study
The challenge Design a milk replacer feeding schedule to maximize efficient growth while considering: fat content of milk replacer encourage grain intake prior to weaning maintain growth rate through weaning cold weather feeding implications Using a higher milk volume feeding schedule and offering calves a higher fat content in a milk replacer does not mean that success at weaning will be compromised. In fact, during 2015 and 2016 research trials at the Grober Young Animal Development Centre (GYADC),...
Inter-annual variations of Poyang Lake area during dry seasons: characteristics and implications
Variations in a lake area constitute an important indicator of the modifications of the lake hydrology. This paper explores the inter-annual variations of the Poyang Lake area during the dry seasons occurring within the 1961 to 2010 period and further quantifies the severity of dryness recently endured during the 2000s. A physically based hydrodynamic model of Poyang Lake established the relation between the lake area and lake level. The lake area was calculated using the observed lake water level. Results...

Every producer has individual opportunities and challenges due to their housing environment and management strategy. The key to maximizing growth, health, and long-term profitability is establishing a sound system of care for your pre-ruminant livestock. No matter the system you choose, ensuring these 5 keys to management are acknowledged and defined for you and your team will enhance the performance of your young stock. Here are the 5 keys to success in young animal nutrition Colostrum: Proven to be the key to...
Improved Performance Through Weaning
Weaning can be a stressful event for calves. Taking the time to wean gradually can help reduce that stress and give the calf time to adjust their eating patterns to include more starter. It is important to establish the right time to wean ensuring (a) the calf has received enough milk for optimal growth and (b) is consuming enough starter to wean gently and not lose body condition after weaning. The Grober Young Animal Development Center (GYADC) compared weaning over 5 days and 10 days in individual or paired...
