More than 25 years at producers' service!

In the fall of 1995, the ministère de l'Agriculture des Pêcheries et de l'Alimentation du Québec (MAPAQ) made available to Quebec beef cattle breeders the Programme d’analyse des troupeaux de boucherie du Québec (PATBQ) in order to facilitate herds performance monitoring.

In the spring of 2016, the administrative mandate was handed over to the Centre de développement du porc du Québec (CDPQ) to ensure the delivery of the program to users, as well as its development according to the needs of the beef cattle industry.

An essential program, a reference guides for the beef sector

The Programme d’analyse des troupeaux de boucherie du Québec (PATBQ) is a technical-economic and genetic evaluation tool. It act as a reference that guides the beef industry, thanks to its database and analysis software, and it supports breeders for purebred or commercial beef cattle selection decisions. It allows the compilation of on-farm herd data in order to determine strengths and weaknesses of a business. In the medium-term, it helps to increase the business' income and provides valuable services to several beef industry skateholders.

Analysis software and database  

The PATBQ's analysis software and database provides, among other things, performance and pedigree data from nearly 700,000 purebred and cross-bred beef cattle.

In 2020-2021, 266 Quebec beef cattle producers, as well as around 30 stakeholders in contact with these producers (advisors from the Bovi-Expert Group and MAPAQ, supervisors and data entry agents), used the PATBQ software.

Purebred Breeders/Expected Progeny Differences (EPDs)

The program support purebred breeders in their efforts of genetic improvement. Herd performance is combined with pedigree information and translated into Expected Progeny Differences (EPDs), which are updated 12 times a year. This data allows them to progress in terms of high economically important traits, such as:

  • Calf growth

  • Maternal ease

  • Reproduction

  • Carcass quality

  • etc.

Names and abbreviations of EPDs frequently encountered in beef production are available here.

Commercial Producer/Across Breed Comparison (ABC)

Commercial producers also benefit from Across Breed Comparisons (ABC) data reference to support their selection decisions, such as replacement heifers choice. As with EPDs, this data can be expressed in percentile ranks. The producer can therefore easily, for example, classify his cows in decreasing order of calving ease genetic potential to guide his management decisions (e.g. culling).

Attestra electronic tag activation (formerly ATQ)

Another interesting feature of PATBQ is that it offers the option of automatically transferring the electronic tag activation and mortality information to Attestra. Then, the producer doesn't have to report the same information in two different places.

Summary of the main benefits for users

In addition to constituting an essential reference for the beef sector, the data and functionalities of the PATBQ allow users to :

  • Achieve genetic progress in purebred and commercial herds for economically important traits,

  • Compare herd performance with regional and provincial benchmarks in order to identify improvement priorities,

  • Improve breeding practices and herds productivity and profitability,

  • Simplify information exchanges between producers and provincial beef databases (Attestra, PBQ, FADQ, etc.),

  • Deliver consulting services adapted to each farm's priorities.

Group strength !

Participating in PATBQ allows you to follow the evolution of your herd's performance year after year. You can also compare yourself with other registered farms in your region and province, which greatly supports decision-making. With this tool, we know where we are going! "

A dynamic team always there for you

The team dedicated to PATBQ is multidisciplinary, including breeding specialists, geneticists and other professionals with common objective of offering the best tool to program members in order to ensure herds genetic progress.
