Chicken offals as pig feeds

Could any one  introduce me to a simple process on  how i can process  broiler offals (heads, feet, viscera) into protein source for my pigs at the farm. I feel am wasting alot of good protein whenever i slaughter my broilers and i burry those valuable wastes. thanks


Dear Isaac,

The TECA Team is currently asking for information about your question on recylcing broiler offals for pigs. We will come back to you as soon as possible.

Best regards,



Dear Issac,

Through FAO document repository, we have found the following publications that may help you:

Please, pay a special attention to the feed/food safety issues (for humans and animals) associated with the use of animal waste. We urge you to read carefully about sanitary issues related to the “recycling” of any animal waste: “Organic wastes are subject to rapid deterioration and contamination by microorganisms, some of which are extremely pathogenic (it means that they can cause severe health issues)”!

We recommend you to read:

Feed from animal wastes: state of knowledge => Chapter 3 HEALTH HAZARDS AND SAFETY CONSIDERATIONS (http://www.fao.org/docrep/004/x6518e/X6518E04.htm#ch3

We hope this would help,

Best regards,

The TECA Team

The ‘one-liner’ request from Ssekatawa Isaac refers – he wanted to know more about feeding poultry waste to his pigs. This is an interesting question.

Challenging opportunities then, most of which are based upon the extent of the industrial processing that can be introduced to handle the quantities of wastes available. And, herein is the first issue – the need to invest in waste disposal and/or processing methods that will handle what are potentially highly toxic materials. Given the location of the majority commercial-scale broiler producers/plants close to consumers, this brings further issues of handling, disposal and use (for best) within an industrial setting. This, notwithstanding, local by-laws in the low-income countries are frequently flouted, and we have all seen broiler plants located adjacent to residential communities.

So, pending environmental sensitivity, read the introductory section ‘General’ in the reference source provided by the TECA Team under ‘Health Hazards & Safety Considerations’ at: http://www.fao.org/docrep/004/x6518e/X6518E04.htm#ch3. The potential contamination of foods derived from waste poultry materials – heavy metals, herbicides, hormones, veterinary drugs, wood preservatives and more are sufficient to scare you (i.e. you, the client buying pig meat) off this source of food for life. That is, if your buyers ever find out.

The extent of the high temperatures that are required when processing (according to the second TECA reference source at: http://www.fao.org/docrep/003/w3647e/W3647E06.htm#ch6) described the loss of feed quality that comes from the destruction of key amino-acids and reduced levels of lysine. So, even supposing that you can work your way through those tables of recommended contents for protein paste, feather meal, meat & bone meal and similar, you would still need to have access to the industrial plant with which to produce them. Alternatively, perhaps there is an industrial-scale plant in your region to which you can deliver your pre-set quantities of poultry waste; and buy back the meal produced.

Note Cuban experience from the 10-year period leading up to the mid-80s in the text (all the FAO texts provided by the TECA Team are dated)[1] and imagine the investment required to service 20 waste food processing plants that eventually provided fed for 400-500 thousand pigs. Only in a centrally-planned economy can you marshal the processing, logistics, storage, transport, technical skills and more required and, importantly, state financing for an industry that has mixed value.

If you’re a small-scale broiler producer consider the production of biogas from poultry wastes – for all non-commercial materials. There is more information to help with choices at:

http://answers.practicalaction.org/our-resources/collection/biogas-6. Download the ‘Biogas Digest’ and explore basics, application, products and cost benefits. Just about every low-income country has explored biogas development with public sector R&D, design and demonstration plants, and sometimes commercial application.

Convert wastes into a source of energy and you can by-pass all those difficult health and safety issues. Use the biogas on site or sell into the local community and use those off-set costs and/or income derived to purchase alternative feeds such as soya, groundnut and/or blood meals with which to feed those pigs – much easier to handle, store and feed.

Who was it said that agro-production on small-scale should be easy?
