In this project, sheep wander randomly while shepherds circulate trying to herd them. This project is inspired by two simpler models: one of termites gathering wood chips into piles and one of moving sheep. You can also Try running it in NetLogo Web

Set up an in-house management system to identify and eliminate underperforming animals.ДЇor more information on flock genetics get in contact with your local District Wool Manager.If you download the NetLogo application, this model is included. This goes for breeding values but also nutritional management.

Select two or three traits which will help you achieve your goal for the flock and perfect these traits before moving onto others.

Get the foundation right, itвЂ™s not just about breeding values alone, visualize the structure of the animals and take into consideration the environment theyвЂ™ll be living in.

Develop a goal/objective for the flock, think about specific profit drivers and create a breeding plan that will achieve these goals.

For example, if ewe lambs donвЂ™t meet certain growth weights for age the progeny just wonвЂ™t produce to their full genetic potential.вЂќД¬raigвЂ™s advice for choosing the right genetics and ongoing flock management: вЂњIn-house management of your stock, in my mind, is the most important thing to get right. The condition score of an animal will have an impact on the profit drivers of the flock,вЂќ says Craig. You can buy the best genetics but if you manage them poorly then your production wonвЂ™t reflect your genetic inputs. вЂњThe biggest impact to production is nutrition. Selecting the right genetics is only part of the equation, the other part is management. Only a visual assessment can ensure the animal stands square, has no dip in the back, stands on their toes and follows through from the hips to shoulders.вЂќ If traits are the ingredients, nutrition is the chef вЂњA good foundation to build upon is vital to the success of the flock, animals need to have good structure. Getting the balance right is the trick, if you chase wool traits you could impact fertility or if you chase growth traits you could impact wool cut.вЂќДЄssessing animals based on appearance still forms part of the equation and thatвЂ™s a point Craig makes when considering the complete process. Selecting two or three traits to implement into a flock before re-evaluating the flockвЂ™s objectives is good practice. вЂњGoing after every metric at the same time overlooks the key breeding objectives of the flock and could result in an animal that isnвЂ™t fit for purpose. вЂњIt doesnвЂ™t pay to get greedy when it comes to breeding values,вЂќ says Craig.

Only its not that simple, as Craig explains. In theory, a super sheep exists, scoring the highest possible marks for every trait. On top of individual ASBVs, buyers can view combined indexes which weight certain traits and return a single number which clearly ranks animals. Australian Sheep Breeding Values (ASBVs) provide buyers with data to tailor animals to the specific goals and objectives of a breeding program.ДЄSBVs are available for many different traits including: Gone are the days of judging a ram by its appearance alone. Increasing our ability to accurately measure and manage the performance of a breeding program,вЂќ he says. We can now measure traits which we canвЂ™t see or touch. вЂњThe Merino has come a long way in the last 40 years and thatвЂ™s a credit to our stud breeders. An increase Australia-wide in recorded breeding values has undoubtedly made the job of selecting a purpose bred animal easier, however, itвЂ™s not a case of picking the best of everything and hoping to achieve the best outcome on any given property.Д®lders Goulburn district wool manager, Craig Pearsall helps explain the process by drawing on his 40 yearsвЂ™ experience, working closely with MerinoвЂ™s on the south west slopes of the Southern Tablelands in New South Wales. The same is true when it comes to choosing genetics to improve or start a flock.
