Two Agfacts have been produced to cover the topic of ‘records for beef producers’:
The recording systems outlined present a package of practical records for beef producers. You can change them to suit your particular needs. The number of records maintained and the detail recorded will vary according to individual needs and how the information is to be used. Each record should have a specific objective and be used for that purpose.
While many beef producers achieve genetic improvement in their herds without keeping individual cow records, a sound management program and careful subjective selection assessment are required. Individual cow records allow for objective assessment of heritable and repeatable traits. They enable you to accurately measure genetic improvement and monitor individual cow fertility and production.
The record formats shown in this Agfact cover individual breeding cow records that can be applied to breeding herds. The emphasis is on recording production information that is useful in selection decisions for herd improvement and herd fertility monitoring.
What you record will depend on your needs and your capability to record information. The records you choose to keep should be related to the purpose you are going to use them for, such as selecting heifers, culling cows or forming a nucleus herd for breeding bulls.
Producers interested in performance recording and registering animals with BREEDPLAN will require more detailed record keeping. Information recorded should mostly be on:
General records of:
Annual records of:
If you are going to record information about individual animals, you need to be able to identify each animal in the herd over a number of years. The easiest way to achieve this at present is to use National Livestock Identification System (NLIS) electronic devices (ear tags / rumen bolus), or plastic ear tags.
The Australian beef industry has adopted a whole-of-life identification system (NLIS). The electronic ID devices used in this system are easily linked to computer-based record-keeping systems commonly available. For further information, see National Livestock Identification System.
Plastic ear tags and NLIS ear tags are not loss-proof! Where permanent identification is necessary, a back-up management tag or ear tattoo is desirable.
Adopting any ear tag or NLIS identification program is pointless if you do not plan to ‘mother up’ cows with their annual calf drop, or record individual animal information.
Ear tags and NLIS tags/boluses are used to give an individual number, to indicate age and, if required, to show the breeding of the cow or cow group. For example, ‘810’ may represent cow number 10, born in 1998 — the first number shows the year of birth and the following numbers identify the individual cow.
Different-coloured tags or the addition of letters above the identification number can be used to record the sire. Cows that fail to rear a calf can have their ear tag notched to identify them for culling and disposal.
A useful alternative to the common plastic ear tag is the pink ear tag system — note that the pink ear tag system will be reviewed in 2006, in conjunction with the rollout of NLIS. Calves can be tagged with pink ear tags (the pink colour denoting HGP-free status), individually numbered in addition to displaying the tail tag number. This means you can use the ear tag instead of the tail tag, and have the benefit of using it as a management tag as well.
Calves treated with HGPs can be tagged with orange non-NLIS ear tags — these calves must have their ‘off’ ear (the right ear) punched with a triangular punch.
Two systems exist for tagging calves: tagging at birth or tagging at marking.
Tagging at birth can be done in two ways:
Tagging at marking:
The NLIS tags can be applied at birth or at marketing — this is only done when you wish to record individual animal information.
Having taken the effort to implement an identification system, the next step is to decide upon a system of office records to store the information you wish to keep.
A range of options exist for keeping permanent herd records in the farm office. Traditionally the most versatile of all these options was the use of cow record cards, one card for each cow. However, with the developments in technology, both simple and advanced computer software programs for herd recording are now available. Laptop computers can also be used in the yards to avoid duplication of information.
The National Livestock Identification System provides the direct link to computerised office records.
Individual breeding cow records need to be kept in a simple, easy-to-use format. Cow record cards have the following advantages:
An example of a cow record card is given to the right. A record card size 12.5 cm × 20 cm is recommended. On the back of the card, vaccination and health details can be recorded.
An alternative to using cards is to use pages in a loose-leaf folder, with one page per cow. This gives the flexibility to move record pages into groups, but this method is more cumbersome than a card system.
Computer programs are rapidly becoming the most preferred and reliable source of herd recording.
Herd bulls can also be recorded on a computer or card system. The card entries can show age, breeding description, vendor, purchase price, annual joining records, health treatments, frame size, testicular size, and details on breeding soundness and identification.
By adopting a card system in the office, all you need in the paddock and the yards is a notebook with headings drawn up for the information you want to keep. Transfer the details as soon as possible, straight onto the cow record cards or computer, taking care to avoid any duplication.
Notebooks used in the paddock and yards can be lost, damaged or fouled up easily. Use a biro, rather than a pencil, to record notebook entries. Pencil entries can become obscure if the notebook gets dirty or wet.
If you do not wish to adopt a cow card system, two other useful records you can keep are a mating group record and a calving book.
This is a group record and not an individual record, although it does allow you to record details on individual cows within the group (see the example below). The main advantage of a mating group record is to check on group fertility (both bull and cows).
If you use cow record cards, then keep mating group records in the notebook. This avoids duplication.
The mating group is a useful herd management record to identify bull fertility problems in both single-sire and multiple-sire joining. It also helps with examining calving spread. Not all the cows joined in each mating group will calve with other cows from that joining group.
The calving book (see extract below) allows you to record calving details as cows calve in their calving groups. It is a paddock notebook and the key record required for a software or cow card system.
The layout illustrated is taken from the calving book produced by BREEDPLAN. The format shown is recommended because:
If the calving book is the only record kept, then you will have all the calves born listed together, along with a record of the cows that calved.
Cows that failed to calve need to be recorded also.
Individual breeding-cow records will allow you to utilise performance information for selection. Often, records will have to be adjusted to make meaningful comparisons between individuals. Remember that comparisons can be made only between animals run together and treated alike.
Records must be relevant to your purpose and must be recorded with ease. Ease of recording is dictated by:
Beef Cattle Advisory Officers are available to assist beef producers to develop recording programs for their individual herds.
