This year two courses were hosted at Brunchilly and Alexandria, with participants travelling from Helen Springs, Soudan and Gallipoli Stations. Right: Participants from Helen Springs identify species in red country DEPARTMENT OF RESOURCES BARKLY BEEF www.nt.gov.au/dor 1 The courses are offered every two years and are a great opportunity for men and women that have just started a career in the pastoral industry, or are new to the Barkly region, to learn about cattle production on the Barkly. The principles of each topic are based on those previously developed for other regions in the Northern Territory, but have been customised in line with Barkly information. A range of topics are covered over a 1-2 day course including pasture species and dynamics which covers the major Above: Participants from Brunchilly and Helen Springs differences between red and black soils, perennial species versus annual species and the different stages of plant growth and what this means for pasture quality. The next topic, land condition and monitoring, follows on well and introduces the concept of the ABCD framework for assessing land condition, and how this can affect carrying capacity and therefore profitability in a beef business. The course teaches how to recognise the major weed species of the Barkly, and what to do or who to contact if they are found. Participants are taught how to recognise poisonous plants and the symptoms of poisoning to cattle. A session on biodiversity highlights the importance of the Barkly region, the different species that reside here and how this is related to cattle production. The course is finished off with a session on animal nutrition. This topic covers the basics of the ruminant’s Above: Casey Collier (DoR Tennant digestive system, nutrient requirements and leads on to Creek) assists participants identify flora explaining the major supplementation regimes across Northern species at Alexandria Australia. Interactive sessions are held throughout the course where participants are taken out into the paddock and shown the main differences between red and black soils, how to identify different species of grasses, forbs and shrubs, and identify the differences in land condition. Overall, there was an overwhelming positive response from participants and courses will again be offered in 2014. Who’s New in the Zoo? Jane Douglas is the new face around the Tennant Creek - Department of Resources office. Jane joined the Pastoral Production team on the 30th April this year as a Technical Officer, Level 3. Jane will be working mainly on the Barkly district projects. She transferred from the Victoria River Research Station where she completed a 2 ½ year stint as a Technical Officer. Jane grew up on a high country sheep, beef and deer station in the South Island of New Zealand. Following high school, she commenced a Bachelor of AgriScience degree at Lincoln University. However after 2 years, the need to get back to the stations was too DEPARTMENT OF RESOURCES BARKLY BEEF www.nt.gov.au/dor 2 strong, so she went back to working on extensive sheep and beef stations around the South Island. In 2006, Jane flew to the Northern Territory for a 6 month working holiday at Tipperary Station. It didn’t take long for the outback lifestyle, and lack of snow, to convince Jane to stick around. She then went on to other cattle properties around Proserpine, QLD and Derby, WA, as well as a stint at working the wheat harvest in southern WA. In her 4 years of working in various places around Australia Jane found that the Territory had been her favourite place, so in 2009 the move was made to the Victoria River District, first to Victoria River Downs Station, then to the Victoria River Research Station (Kidman Springs) as a DoR Technical Officer in November 2009. While at Kidman Springs, her ongoing interest in Agri-Science and the research and development work being performed by the Pastoral Production team prompted Jane to resume her Agri-Science degree studies by correspondence. When the opportunity to further her career within the Department became available, she jumped at the chance to join the research and extension side of the Pastoral Team and so here she is, DoR Tennant Creeks’ newest recruit. Say Hello to her at the office, Tennant Creek Show or around the district.

This practical guide to managing heifers has been developed using results of recent research and existing knowledge of best practice heifer management. It provides practical information on management practices and the biology of heifers to help cattle producers to make informed management decisions. This publication is an outcome of MLA-funded projects conducted in northern Australia. Although the publication has focused primarily on heifer management in extensive beef herds, the principles have equal application to all beef herds across northern Australia despite any differences in scale of operations, breeds, climatic conditions or pasture types. It is a short, readable guide to best practice management written for graziers, station managers, head and other stockmen and students of animal husbandry. • Digital copies can be downloaded at http://www.mla.com.au/Publications-tools-and- events/Publication-details?pubid=5823 • Hard copies can be ordered by calling the MLA membership services hotline on 1800 675 717 or email [email protected] Or from the Department of Resources - Email: [email protected] DEPARTMENT OF RESOURCES BARKLY BEEF www.nt.gov.au/dor 3 Key Messages for Heifer Management Improving re-conception rates in first-calf heifers can significantly improve herd profitability. General principles that can be applied to the management of replacement heifers include: Body condition at mating has the greatest effect on heifer fertility Consecutive stocking and good pasture in heifer paddocks are the cheapest ways to achieve good body condition. Supplements may be cost effective. Heifers should be segregated from the breeder herd, grazed on the best paddocks and may need supplements over the post-weaning dry season to reach critical mating weight. The majority of heifers should be at or above the critical mating weight (CMW) at the start of joining. The CMW for Bos indicus heifers is 320-340kg. Bos indicus heifers tend to reach puberty at heavier weights and at a later age than Bos taurus heifers. The heifer needs to have a body condition score (BCS) of 3.5 (on BCS scale of 1-5) or higher at calving to maximise the chance of getting pregnant again while rearing her calf. If heifers are selected before joining, this should be based on growth over the post-weaning year, and not on weight at weaning, which largely depends on age. Mate more heifers than are needed for replacement using young bulls evaluated for breeding soundness, ‘calving ease’ and ‘low birth weight’. Select replacement heifers from those that get pregnant early in the joining period- and on temperament. Ideally, heifers should be mated for only three cycles (63 days). On extensive properties, pregnancy diagnosis can be used to identify heifers that conceived early in the mating period. Yearling mating will give good results only if heifers are heavy enough (on good country) and are of early-maturing breed types. The best type of heifer will be that suited to the environment and target market. Genetic improvement is faster through crossbreeding than through selection. Bull selection will have a much greater impact on herd improvement than selecting heifers or cows. Calf losses in first-calf heifers are often high (>20%) and mostly occur around the time of birth. Muster and wean first calf heifers before the main breeder herd. Wean calves early, down to 100kg (3 months), or even earlier if heifer survival is at risk. Vaccinate all heifers against botulism and against any other diseases that could have significant economic impact. Maiden heifers are a good group to use if an artificial insemination program is planned.

The manual updates and expands on the Katherine Best Practice Manual released in 2009. The manual was produced with funding support from Meat & Livestock Australia (MLA). The manual is a comprehensive snapshot of how to manage properties and run cattle in the Top End. There are Chapters on Infrastructure and Station Development, Land management, Cattle Breeding, Cattle Management, Cattle Nutrition, Animal Health, Floodplain Production and other topics of interest. The manual is available in three formats, a hard cover book, online (on the DoR and MLA web sites) and as a CD. Most of the hard cover books have been allocated, but CDs will be available to supply requests for copies. Books will be sent to or delivered to Top End producers by Extension Officers. Copies of the book will also be available in Departmental and Community Libraries.
