WELCOME TO THE DEVANAH 2025 ANGUS BULL SALE
Neil, Jo-anne and Damien have been breeding cattle and selling bulls in the Central West of NSW since 1987, initially at Cudal and since 1990 at Forbes.
Our focus is supplying docile, medium framed bulls to produce long lived, fertile females and steers who do well on grass or in the feedlot. We aim at good weights, muscling and adequate IMF/fats to ensure heifer fertility and for carcases to grade into premium brands. We are very strict on culling empties and only have one calving per year.
These bulls assessed by Roger Evans No: 13411 and Lonie Stone No: 1344. All animals were weighed, scanned for eye muscle, rib and rump fat and intra muscular fat, bulls scrotal circumference and temperament, legs, feet, muscle score, and naval assessed.
All bulls have been:
• Backlined with Baymec for lice and internal parasites
• Backlined with Fasitak for fluke (an issue just arisen in recent year)
• Vaccinated with 8 in 1 for year round protection against clostridial diseases
• Vaccinated with Piliguard to help with Pink Eye infection
• Vaccinated with Pestiguard
• Vaccinated with Lepto Shield
• Vaccinated with Bovilis MH + IBR
We were MN3 for Johnes Disease for a number of years until that scheme was discontinued. Since then we have chosen to be JBAS-6. Our Biosecurity program is overseen by Forbes Veterinary Clinic.
We have run these animals together since weaning and have aimed at having them in forward condition, fit and ready to work. They still have a couple of years before they reach their mature size, so they need to be looked after to ensure they grow to their genetic potential.
Regards, Neil , Jo and Damien

recessive genetic conditions
This is information for bull buyers about the recessive genetic conditions, Arthrogryposis Multiplex (AM), Hydrocephalus (NH), Contractural Arachnodactyly (CA) and Developmental Duplications (DD).
Putting undesirable Genetic Recessive Conditions in perspective
All animals, including humans, carry single copies (alleles) of undesirable or “broken” genes. In single copy form, these undesirable alleles usually cause no harm to the individual.
But when animals carry 2 copies of certain undesirable or “broken” alleles it often results in bad consequences. Advances in genomics have facilitated the development of accurate diagnostic tests to enable the identification and management of numerous undesirable or “broken” genes.
Angus Australia is proactive in providing its members and their clients with relevant tools and information to assist them in the management of known undesirable genes and our members are leading the industry in their use of this technology.
What are AM, NH, CA and DD?
AM, NH, CA and DD are all recessive conditions caused by “broken” alleles within the DNA of individual animals. When a calf inherits 2 copies of the AM or NH alleles their development is so adversely affected that they will be still-born.
In other cases, such as CA and DD, calves carrying 2 copies of the broken allele may reach full-term. In such cases the animal may either appear relatively normal, or show physical symptoms that affect their health and/or performance.
How are the conditions inherited?
Research in the U.S. and Australia indicates that AM, NH, CA and DD are simply inherited recessive conditions. This means that a single gene (or pair of alleles) controls the condition.
For this mode of inheritance two copies of the undesirable allele need to be present before the condition is seen; in which case you may get an abnormal calf. A more common example of a trait with a simple recessive pattern of inheritance is black and red coat colour.
Animals with only one copy of the undesirable allele (and one copy of the normal form of the allele) appear normal and are known as “carriers”. What happens when carriers are mated to other animals?
Carriers, will on average, pass the undesirable allele to a random half (50 %) of their progeny.
When a carrier bull and carrier cow is mated, there is a 25% chance that the resultant calf will inherit two normal alleles, a 50% chance that the mating will result in a carrier (i.e. with just 1 copy of the undesirable allele, and a 25% chance that the calf will inherit two copies of the undesirable gene.
If animals tested free of the undesirable gene are mated to carrier animals the condition will not be expressed at all. All calves will appear normal, but approximately half (50%) could be expected to be carriers.
How is the
genetic status of animals reported?
DNA-based diagnostic tests have been developed which can be used to determine whether an individual animal is either a carrier or free of the alleles resulting in AM, NH, CA or DD.
Angus Australia uses advanced software to calculate the probability of (untested) animals to being carriers of AM, NH, CA or DD. The software uses the test results of any relatives in the calculations and the probabilities may change as new results for additional animals become available.
The genetic status of animals is being reported using five categories:
AMF Tested AM free
AMFU Based on Pedigree AM free - Animal has not been tested
AM_% _% probability the animal is an AM carrier
AMC Tested AM-Carrier
AMA AM-Affected
For NH, CA and DD, simply replace AM in the above table with NH, CA or DD.
Registration certificates and the Angus Australia web-database display these codes. This information is displayed on the animal details page and can be accessed by conducting an “Database Search” from the Angus Australia website or looking up individual animals listed in a sale catalogue.
Implications for Commercial Producers
Your decision on the importance of the genetic condition status of replacement bulls should depend on the genetics of your cow herd (which bulls you previously used) and whether some female progeny will be retained or sold as breeders.
Most Angus breeders are proactive and transparent in managing known genetic conditions, endeavouring to provide the best information available. The greatest risk to the commercial sector from undesirable genetic recessive conditions comes from unregistered bulls with unknown genetic background. The genetic condition testing that Angus Australia seedstock producers are investing in provides buyers of registered Angus bulls with unmatched quality assurance.

Understanding the TransTasman Angus Cattle Evaluation (TACE)
What is the TransTasman Angus Cattle Evaluation?
The TransTasman Angus Cattle Evaluation is the genetic evaluation program adopted by Angus Australia for Angus and Angus influenced beef cattle. The TransTasman Angus Cattle Evaluation uses Best Linear Unbiased Prediction (BLUP) technology to produce Estimated Breeding Values (EBVs) of recorded cattle for a range of important production traits (e.g. weight, carcase, fertility).
The TransTasman Angus Cattle Evaluation is an international genetic evaluation and includes pedigree, performance and genomic information from the Angus Australia and Angus New Zealand databases, along with selected information from the American and Canadian Angus Associations.
The TransTasman Angus Cattle Evaluation utilises a range of genetic evaluation software, including the internationally recognised BLUPF90 family of programs, and BREEDPLAN® beef genetic evaluation analytical software, as developed by the Animal Genetics and Breeding Unit (AGBU), a joint institute of NSW Agriculture and the University of New England, and Meat and Livestock Australia Limited (MLA).
What is an EBV?
An animal’s breeding value can be defined as its genetic merit for each trait. While it is not possible to determine an animal’s true breeding value, it is possible to estimate it. These estimates of an animal’s true breeding value are called EBVs (Estimated Breeding Values).
EBVs are expressed as the difference between an individual animal’s genetics and a historical genetic level (i.e. group of animals) within the TACE genetic evaluation, and are reported in the units in which the measurements are taken.
Using EBVs to Compare the Genetics
of Two Animals
TACE EBVs can be used to estimate the expected difference in the genetics of two animals, with the expected difference equating to half the difference in the EBVs of the animals, all other things being equal (e.g. they are joined to the same animal/s).
For example, a bull with a 200 Day Growth EBV of +60 would be expected to produce progeny that are, on average, 10 kg heavier at 200 days of age than a bull with a 200 Day
Growth EBV of +40 kg (i.e. 20 kg difference between the sire’s EBVs, then halved as the sire only contributes half the genetics).
Or similarly, a bull with an IMF EBV of +3.0 would be expected to produce progeny with on average, 1% more intramuscular fat in a 400 kg carcase than a bull with a IMF EBV of +1.0 (i.e. 2% difference between the sire’s EBVs, then halved as the sire only contributes half the genetics).
Using EBVs to Benchmark an Animal’s Genetics with the Breed EBVs can also be used to benchmark an animal’s genetics relative to the genetics of other Angus or Angus infused animals recorded with Angus Australia.
To benchmark an animal’s genetics relative to other Angus animals, an animal’s EBV can be compared to the EBV reference tables, which provide:
• the breed average EBV
• the percentile bands table
The current breed average EBV is listed on the bottom of each page in this publication, while the current EBV reference tables are included at the end of these introductory notes. For easy reference, the percentile band in which an animal’s EBV ranks is also published in association with the EBV.
Considering Accuracy
An accuracy value is published with each EBV, and is usually displayed as a percentage value immediately below the EBV.
The accuracy value provides an indication of the reliability of the EBV in estimating the animal’s genetics (or true breeding value), and is an indication of the amount of information that has been used in the calculation of the EBV.
EBVs with accuracy values below 50% should be considered as preliminary or of low accuracy, 50-74% as of medium accuracy, 75-90% of medium to high accuracy, and 90% or greater as high accuracy.
Description of TACE EBVs
EBVs are calculated for a range of traits within TACE, covering calving ease, growth, fertility, maternal performance, carcase merit, feed efficiency and structural soundness. A description of each EBV included in this publication is provided on the following page.

Higher EBVs indicate more body condition of mature females.
Higher EBVs indicate heavier mature weight.
Higher EBVs indicate heavier live weight.
Lower EBVs indicate shorter time to calving.
Higher EBVs indicate larger scrotal circumference.
Higher EBVs indicate heavier carcase weight.
Higher EBVs indicate larger eye muscle area.
Genetic differences between animals in fat depth at the 12/13th rib site in a 400 kg carcase. Higher EBVs indicate more fat.
Genetic differences between animals in fat depth at the P8 rump site in a 400 kg carcase. Higher EBVs indicate more fat.
RBY % Genetic differences between animals in boned out saleable meat from a 400 kg carcase. Higher EBVs indicate higher yield.
IMF % Genetic differences between animals in intramuscular fat (marbling) at the 12/13th rib site in a 400 kg carcase.
NFI-F kg/day
Genetic differences between animals in feed intake at a standard weight and rate of weight gain when animals are in a feedlot finishing phase.
Doc % Genetic differences between animals in temperament.
Claw Set score Genetic differences in claw set structure (shape and evenness of claws).
Foot Angle score Genetic differences in foot angle (strength of pastern, depth of heel).
Higher EBVs indicate more intramuscular fat.
Lower EBVs indicate more feed efficiency.
Higher EBVs indicate better temperament.
Lower EBVs indicate less curl of the claw set.
Lower EBVs indicate more heel depth.
Leg Angle score Genetic differences in rear leg structure when viewed from the side (angle at front of the hock). Lower EBVs indicate a less angular leg angle.
$A $
$A-L $
Genetic differences between animals in net profitability per cow joined in a typical commercial self replacing herd using Angus bulls. This selection index is not specific to a particular market end-point, but identifies animals that will improve overall net profitability in the majority of commercial, self replacing, grass and grain finishing beef production systems.
The $A-L index is similar to the $A index but is modelled on a production system where feed is surplus to requirements for the majority of the year, or the cost of supplying additional feed when animal feed requirements increase is low.
While the $A aims to maintain mature cow weight, the $A-L does not aim to limit the increase in mature cow weight as there is minimal cost incurred if the feed maintenance requirements of the female breeding herd increase as a result of selection decisions.
Higher selection indexes indicate greater profitability.
Higher selection indexes indicate greater profitability.
