- Stockowner Biosecurity
- Stockowner Biosecurity (PDF: 364 kB)
- Authors: Sandy Clark, Colin Mason
- ISBN: 1854828975
- Published:Apr 2009
- The prevention of infectious disease to livestock farm herds and flocks is more important as margins tighten and exotic diseases threaten. Constant attention to detail and vigilance for signs of disease are vital for the protection of your animals and business. Stockowners need to consider the disease risks when employing contractors, helping neighbours, attending livestock auctions, agricultural shows and visiting any facility where animals are kept. There are guidelines which, if adhered to, can prevent unnecessary disease incursion with the associated loss of income and hardships.
- Biodiversity And Animal Health
- Biodiversity And Animal Health (PDF: 386 kB)
- Authors: D J Roberts, S Stewart, and C Mason
- ISBN: 1854828827
- Published:Mar 2009
- Both biodiversity and animal health are important issues on livestock farms. Carefuly integrated farm management can benefit both wildlife and livestock and reduce diffuse pollution. This note summarises some of the examples where improving biodiversity can also improve animal health and other examples where there is a potential conflict between the two areas.

- Authors: Dave Merrilees & Seamus Donnelly
- ISBN: 1854828592
- Published:Jan 2007
- Woodchip corrals have been used as a cost-effective system for overwintering cattle compared with conventional housing. Operational performance in Scotland and elsewhere indicates that not only is stock health and welfare better from rearing outdoors but economic performance is also enhanced.
- Condition Scoring The Modern Dairy Cow
- Condition Scoring The Modern Dairy Cow (PDF: 460 kB)
- Authors: Dr Geoff Pollott
- ISBN: 1854828444
- Published:Jan 2007
- The condition score of a cow is a useful piece of information to have, particularly when it is recorded periodically throughout lactation and acted on.
- Managing Body Condition Score In Dairy Cows
- Managing Body Condition Score In Dairy Cows (PDF: 164 kB)
- Authors: Derek Kennedy
- ISBN: 1854828436
- Published:Dec 2007
- Dairy cows, like most other animals, mobilise bodyfat during early lactation to meet the substantial energy demands of milk production. This is especially characteristic of modern dairy cows. By keeping cows in the correct body condition, good productivity can be achieved and health and welfare problems reduced.
- Biosecurity – Vehicles Visiting The Farm
- Biosecurity – Vehicles Visiting The Farm (PDF: 183 kB)
- Authors: Derek Kennedy, Mark Crawshaw
- ISBN: 1854828428
- Published:Dec 2007
- There are a number of actions individual farmers can take to minimise the risk of vehicles bringing disease onto their farms. In the event of an infectious disease outbreak, farmers should have a contingency plan. In some cases, the authorities may specify what minimum biosecurity measures they would expect farmers and farm visitors to adhere to.

- Health Status Of Breeding Cattle For Sale
- Health Status Of Breeding Cattle For Sale (PDF: 54 kB)
- Authors: George Caldow, Sheila Rusbridge, Mark Crawshaw, George Gunn
- ISBN: 1854827715
- Published:Feb 2003
- The health status of animals at sale is important for two reasons. Firstly the animal itself needs to be free from the major diseases if it is to breed successfully and have a long and productive life. Secondly these animals should be free from the major diseases so that they do not endanger either the health of the other animals at the sale or the health of the herd that they are sold in to.
- Design Of Cattle Farm Steadings For Maximum Biosecurity
- Design Of Cattle Farm Steadings For Maximum Biosecurity (PDF: 60 kB)
- Authors: Mark Crawshaw, Basil Lowman, Jack Bishop, George Caldow
- ISBN: 1854827421
- Published:Jan 2003
- It is obviously difficult to redesign existing farm steadings to provide maximum biosecurity. Knowing the ideal layout to minimise the entry of infectious disease will allow any future modifications/extensions etc to enhance rather than detract from the biosecurity of the unit.

- Recommendations For The Design Of New Safe & Efficient Cattle Handling Systems
- Recommendations For The Design Of New Safe & Efficient Cattle Handling Systems (PDF: 166 kB)
- Authors: Dr Simon Turner
- ISBN: 1854828061
- Published:Oct 2004
- Investing in a new handling system is a major commitment and design faults will either have to be corrected at a later date or contended with for the life of the system. Spending time at the outset developing a safe and efficient design appropriate to your needs is therefore easily justified. As the ease and safety of handling depends largely on how well the behaviour of the animal is exploited, the starting point in the design process should be understanding what features encourage calm movement.
