Hybrid Pig Breeding Improves the Pig Herd

One of the first companies to carry out a hybrid pig breeding program was the British Oil and Cake Millers (COCM) in the UK. Their pig improvement scheme was begun in 1963 because research had shown that many commercial strains of pigs were unable to make the best use of the company's improved pig rations. Work was carried out on the company's farms in the UK with the aim of improving three breeds: the Landrace, the Large White and the Saddleback and to produce a three-way cross hybrid pig with an overall performance that was 25% than the average.  

The scheme started with the purchase of one thousand weaner pigs, of which only 30% were acceptable genetically and visually. All the gilt pigs were performance tested, and the best 12-5% went into the foundation herd. The best sows were subsequently used to breed boars. The selection of boars was so strict that less than one in two hundred and fifty male pigs were finally used. The final hybrid pigs are used for both pork and bacon production.

Most breeders of hybrid pigs work with large numbers and use carefully selected and pure breeds. Two of these breeds are crossed to produce the hybrid sow with the benefits of improved litter numbers, milking ability and better health and vigour. The hybrid sow is then mated to an improved boar of another pure breed to produce the hybrid bacon or pork pig.

Hybrid sows are produced by "multiplying breeders" who get their breeding stock from hybrid breeding companies. These multiplying breeders usually work on a contract basis and are paid by the companies to look after the pigs. The commercial farmer buys his hybrid gilts from the company and the pure bred boars from the same company. A typical hybrid breeding program is shown in the table on the next page."

Providing an Environment Suited to Raising Pigs

The thermal environment is particularly important in pig production as a properly ventilated environment provides numerous benefits to the pig producer. These include:

  • More efficient feed use
  • Enhanced disease control
  • More comfortable working conditions
  • Faster growth rates
  • Reduced  mortality rates

The main object of controlling the pig’s environment is to reduce fluctuations in temperature. This can be achieved by the following:

  • Building on a site that has a suitable micro-climate – the topography of the site will effect the environment in the piggery, as will the orientation of the buildings on the site.
  • Having good construction and proper insulation of buildings – the more dense the materials used in the roof and outer walls, the less variable the internal temperature.
  • Good ventilation – this is required to ensure carbon dioxide and other gases (such as ammonia and hydrogen sulphide), water vapour, dust, body heat, and air borne pathogens are removed from the building
  • Artificial heating/cooling/ventilation systems, for example: fan ventilation, heating for piglets in the farrowing house, and spray cooling or fogging systems for growers, finishers or breeders.

Climate change is likely to lead to an increase in weather variability and the occurrence of extreme events. These changes include long high or low temperature periods, severe storms or flood conditions and drought.  Forward planning when building or upgrading pig housing should therefore take this into account.

Environmental concerns in pig farming, particularly about disposal of effluent as well as emission of greenhouse gases, have led to emergence of new technology to reduce pollution and to recycle as much as possible.   Effluent comprises wastewater from shed cleaning and cooling, runoff from feedlot outdoor piggeries, drinking water spills, manure and waste feed. An example of recycling is when pig manure or biomass is used to create electricity. Decomposing manure creates methane which is captured, transported and used to generate electricity to provide thermal comfort and appropriate conditions for baby piglets.

Some countries require piggeries to operate in an ecologically sustainable manner. This is to protect aspects of the environment such as air, soil, water and biodiversity. Preservation of community amenities and cultural heritage may also need to be considered. Farmers may therefore need to consider control of gas emissions, control of waste material, recycling and reuse of resources.  

Suitable treatment of the large volumes of waste solids and waste water is often the most pressing problem in pig farming. There are many different ways in which these can be  collected and treated including use of drains, pits, channels, solid separation systems (e.g. gravity and sieving methods), pumps, effluent treatment ponds (anaerobic, aerobic, evaporation and solid ponds) and  reed-beds.

Where can this course take you?

The first step towards success is to have a passion and drive for that particular interest area.  With this attitude you can build on knowledge and skills gained in this course to make connections with industry -people, organisations and businesses in the world of pigs.  Hands-on experience with pigs will be easier to find and more useful to undertake when built on top of the learning experiences you have in this course.

Graduates may use what they learn in a whole range of possible situations:

  • As a Piggery manger
  • Free range pig farmer
  • Piggery hand
  • Pig breeder
  • Research Institute roles
  • Manufacturing/supplying products to the pig industry
  • Marketing or sales
  • Wholesale/Retail Specialist
  • Teaching or writing about pigs
  • As a consultant
  • Self sufficiency
  • Caring for "pet" pigs
  • A foundation for further studies

Student Testimonial:
Arnold Taen, Netherlands
Yes [the course was a valuable learning experience]. It is providing me with new insights and development beyond my former knowledge of this subject. It also provides me with a proper basic knowledge to pursue my dreams in this career path.

Studying with ACS provides you with the ability to develop knowledge of agricultural science, but also fosters an "understanding", "awareness" and the right "attitude" that is a necessity to build either a sustainable career or business.

How can I start this course?

You can enrol at anytime and start the course when you are ready. Enrolments are accepted all year - students can commence study at any time. All study is self paced and ACS does not set assignment deadlines.

Please note that if a student is being assisted by someone else (e.g. an employer or government subsidy), the body offering the assistance may set deadlines. Students in such situations are advised to check with their sponsor prior to enrolling. The nominal duration of a course is approximately how long a course takes to complete. A course with a nominal duration of 100 hours is expected to take roughly 100 hours of study time to complete. However, this will vary from student to student. Short courses (eg. 100 hrs duration) should be completed within 12 months of enrolment. Certificates, Advanced Certificates and Awards (eg. over 500 hours duration) would normally be completed within 3 -5 years of enrolment. Additional fees may apply if a student requires an extended period to complete.
If a student cannot submit their assignments for 6 months to ACS, they should advise the school to avoid cancellation of their student
registration. Recommencement fees may apply.
