Non-ruminant animals contribute significantly to Kenya's agricultural economy through diverse products that meet the nutritional and commercial needs of the population. These animals, which do not possess a rumen for digestion, include species such as poultry, pigs, and rabbits. Understanding the range of products derived from non-ruminants and their market potential is essential for agriculture and extension professionals tasked with improving livelihoods and food security. This chapter explores the definition, importance, and varieties of non-ruminant products within the Kenyan agricultural context.

6.1 Non-ruminant products

Non-ruminant products form a vital category within animal agriculture, offering a broad range of consumable and industrial goods. They come from animals such as chickens, pigs, ducks and rabbits, which digest their feed through a simple, single-chambered stomach. The diversity of these products supports many economic activities, from smallholder farming to commercial enterprises, especially in peri-urban and rural areas. The sections below clarify key terms, highlight the importance of these products and describe their types.

6.1.1 Definition of terms

The terminology surrounding non-ruminant products is the foundation of clear communication in agricultural practice and extension services. Precise definitions help an extension officer, a farmer and a trader to speak about the same product in the same way. For example, a pig farmer who asks for a "baconer" price must be understood to mean a pig reared to a heavier weight for curing, not a young pig sold for fresh pork.

Definition of non-ruminant animals

Non-ruminant animals are species that have a single-chambered stomach rather than the multi-chambered stomach of ruminants. They digest their food mainly through enzymes in the stomach and small intestine, not through microbial fermentation in a rumen. Examples include poultry (chickens, turkeys, ducks), pigs and rabbits.

Non-ruminant products defined

Non-ruminant products are all consumable and usable outputs obtained from non-ruminant animals. They include meat, bacon and pork, eggs, hides, skins, feathers and other by-products. The products serve both food and industrial markets, contributing to nutrition and income.

Related terms: primary products and by-products

Primary products are the main outputs raised for direct consumption or sale, such as meat and eggs. By-products are secondary outputs such as feathers, manure and offal, which have commercial value in industries such as fertiliser production, animal feed and crafts.

Distinguishing non-ruminant from ruminant products

Non-ruminant products differ from ruminant products in composition and production cycle. Poultry meat is generally leaner and is ready for sale much sooner than beef or goat meat, which affects market planning and consumer choice.

Market terminology

Non-ruminant products are usually grouped by source species and intended use. The following terms are used in the market:

• Broiler: a chicken bred and raised for meat, ready for sale at a young age.
• Layer: a hen kept for egg production.
• Porker: a pig raised to a lighter weight and sold for fresh pork.
• Baconer: a pig raised to a heavier weight and sold for bacon and cured products.
• Dressed carcass: the animal after slaughter, bleeding and removal of feathers or hair, skin (where removed) and internal organs, ready for sale as a whole carcass or in cuts.

6.1.2 Importance of non-ruminant products

Non-ruminant products play a major role in nutrition, income and livelihood diversification. Their short production cycles and suitability for small-scale systems make them accessible to many farmers, especially women and youth. Their importance spans food security, income, employment, industry and environmental efficiency.

Contribution to food security

Non-ruminant products provide high-quality protein, vitamins and minerals. Eggs and poultry meat are relatively affordable sources of nutrition for urban and rural households, helping to reduce protein shortage in diets.

Economic empowerment and income generation

Smallholder farmers earn income from selling meat, eggs and by-products. Example: a farmer who keeps a few sows can sell weaners or fattened pigs several times a year because pigs grow quickly and have large litters, giving money for household needs and farm inputs.

Employment creation

The non-ruminant sector supports jobs in production, feed supply, slaughter, processing, transport and marketing. A small egg-trading or chicken-dressing business, for example, can employ young people at the farm gate and in local markets.

Raw material supply for industries

By-products supply other industries. Feathers can be processed into feather meal for animal feed, skins can be made into leather goods, and slaughter waste can be used in feed and fertiliser production.

Environmental sustainability and resource use

Non-ruminant animals generally need less land than grazing ruminants, and they can be integrated into mixed farms. Example: a farmer who keeps poultry or rabbits alongside a vegetable plot can use their manure on the crops, improving resource use and reducing waste.

6.1.3 Types of non-ruminant products

The non-ruminant products covered in this unit are meat, bacon and pork, hides and eggs. Each has its own quality requirements, buyers and handling needs. Knowing these helps a producer decide what to sell, in what form and to whom.

6.1.3.1 Meat

Meat is the edible flesh of slaughtered animals and is the main product from broilers, spent layers, ducks, turkeys, rabbits and pigs. It is valued for protein, iron and B vitamins. Example: a broiler farmer can sell birds live, as dressed whole carcasses, or cut into portions such as thighs, breasts and wings for different buyers such as households, butcheries and eating houses.

Meat is marketed in several forms:

• Live animals: birds or rabbits sold to buyers who slaughter them themselves.
• Dressed carcasses: whole slaughtered animals, cleaned and ready for cooking or cutting.
• Cuts and portions: parts such as legs, breasts, wings or rabbit saddles, sold by weight.
• Offal: liver, gizzard, heart and kidneys, sold separately and often popular with buyers.
• Processed meat: sausages, nuggets and similar items made from trimmed meat.

Rabbit meat is very lean and suits buyers who want low-fat meat, while chicken is widely accepted because it is easy to cook and portion. Quality depends on the age of the animal at slaughter, its health, feeding, humane handling before slaughter, and hygienic slaughter and chilling. Meat from slaughtered animals should come from healthy animals passed by a qualified meat inspector before it is sold.

6.1.3.2 Bacon and pork

Pork is fresh meat from pigs, while bacon is pork that has been cured, and often smoked, so that it keeps longer and has a distinct flavour. The type of pig matters: porkers are slaughtered at a lighter weight (roughly 60 to 70 kg live weight) to give tender fresh pork, and baconers are grown heavier (roughly 90 to 100 kg live weight) to give longer sides with a good lean-to-fat balance for curing. Example: a farmer supplying a butchery with fresh pork would raise porkers, while one supplying a bacon processor would raise baconers of a suitable breed and finish.

Common pork cuts and their uses include:

• Leg: roasted fresh or cured as ham.
• Loin: lean chops and roasts.
• Shoulder: roasts, mince and sausage meat.
• Belly: fatty cut, the main source of streaky bacon.
• Back: lean cut used for back bacon.
• Head, trotters and offal: sold separately for stews and processed foods.

Pork must be inspected and cooked thoroughly before eating, because pigs can carry parasites that infect humans if the meat is undercooked. Buyers prefer carcasses with firm pink meat, white firm fat and no unpleasant smell. Pork and bacon should be kept clean and cold between slaughter and sale.

6.1.3.3 Hides

Hides and skins are the outer covering removed from slaughtered animals. Strictly, "hides" come from large animals and "skins" from small ones, but both are raw materials for leather and related goods. Non-ruminant sources include pigs, rabbits and, in some cases, ducks and other poultry. Example: pig skin can be sold to a leather processor, while rabbit skins can be dried and used for crafts, slippers and trimmings.

The value of a hide or skin depends on its quality, which is affected by:

• Flaying damage: cuts and holes made by careless removal reduce the usable area and the price.
• Parasites and disease: mange, scars and lesions leave marks that remain on the finished leather.
• Handling after slaughter: hides left uncleaned and unprotected begin to rot quickly.
• Size and thickness: larger, even skins are more useful to the leather industry.
• Cleanliness: dirt, blood and flesh left on the skin lower quality.

A hide or skin should be removed carefully, cleaned of flesh and fat, and kept cool and clean until it is sold or taken for further treatment. Some pigs are scalded and scraped so that the skin stays on the carcass as pork rind, in which case the skin is eaten rather than sold as a hide.

6.1.3.4 Eggs

Eggs are produced mainly by layer chickens, and also by ducks, turkeys and quails. They are nutritious, containing protein, fat, vitamins and minerals in a convenient package, and they give farmers a continuous income because hens lay throughout the year once mature. Example: a layer farmer with a flock in full production can collect eggs daily and sell them to households, shops and bakeries, whereas meat producers must wait for animals to reach slaughter weight.

An egg is made up of:

• Shell: the protective outer covering, made mainly of calcium; it should be clean and unbroken.
• Shell membranes: thin layers under the shell that help to keep out bacteria.
• Albumen (egg white): the clear protein layer; in a fresh egg it is thick and firm.
• Yolk: the yellow centre rich in fat, vitamins and minerals.
• Air cell: a small space at the blunt end that grows larger as the egg ages.

Eggs are usually sold in trays of 30, sorted by size and cleanliness. Quality is checked by looking at shell cleanliness and soundness, and by candling, which means passing a bright light through the egg to see the yolk, air cell and any cracks or blood spots. Eggs should be collected often, kept clean, and handled gently to avoid cracks.
