When considering the animals you want to rear on your smallholding, it's essential to consider the precise role they will play, as each animal provides a different set of benefits.

1. Chickens:

• Meat: Broiler chickens are raised for their meat.
• Eggs: Layer hens are raised to produce eggs.
• Pest control: Chickens can help control pests in gardens by eating insects and larvae.

2. Ducks:

• Meat: Some breeds, like Pekin and Muscovy, are raised for meat.
• Eggs: Breeds like Khaki Campbell and Indian Runner are known for their egg production.
• Pest control: Ducks also eat insects and slugs, providing natural pest control.

3. Geese:

• Meat: Geese can be raised for meat, with breeds like Toulouse and Embden being popular choices.
• Eggs: Geese produce larger eggs than chickens, although they lay fewer eggs overall.
• Weed control: Geese are excellent grazers and can help control weeds in gardens and orchards.

4. Pigs:

• Meat: Pigs are raised primarily for pork, bacon, and ham.
• Waste management: Pigs can help manage food waste by consuming excess fruits, vegetables, and other food scraps.

5. Sheep:

• Meat: Sheep are raised for meat, typically lamb or mutton.
• Wool: Sheep produce wool, which can be sheared and used for making yarn, clothing, and other textiles.
• Milk: Some breeds, like East Friesian, are used for milk production, which can be used to make cheese and other dairy products.
• Grazing and land management: Sheep can help maintain pastures and control vegetation.

6. Goats:

• Meat: Some goat breeds, such as Boer and Spanish goats, are raised for meat production.
• Milk: Dairy goat breeds like Nubian, LaMancha, and Alpine are raised for milk production, which can be used to make cheese, yogurt, and other dairy products.
• Fibre: Certain breeds, such as Angora and Cashmere goats, produce fibre that can be used for making yarn, clothing, and other textiles.
• Land management: Goats are known for their ability to browse and clear brush, making them useful for controlling weeds, undergrowth, and invasive plant species.

7. Cows:

• Meat: Beef cattle breeds like Angus, Hereford, and Charolais are raised for meat production.
• Milk: Dairy cow breeds like Holstein, Jersey, and Guernsey are raised for milk production, which can be used to make cheese, butter, yogurt, and other dairy products.
• Draft animals: In some cases, cattle, particularly oxen, can be trained as draft animals for pulling carts or ploughs.

8. Donkeys and mules:

• Draft animals: Donkeys and mules are often used as draft animals for pulling carts and ploughs, as well as carrying loads.
• Land management: They can help maintain pastures through grazing.
• Guard animals: Donkeys can also act as guard animals, protecting livestock from predators such as coyotes or wolves.

9. Horses:

• Draft animals: Horses can be used for farm work, including pulling plows, carts, and other equipment.
• Riding: Horses can be used for riding, transportation, and recreational purposes.

10. Rabbits:

• Meat: Rabbits are raised for their lean, tender meat.
• Fur: Rabbit fur can be used for clothing and other textiles.
• Manure: Rabbit manure is an excellent fertilizer for gardens and can be used to improve soil fertility.

11. Bees:

• Honey: Honeybees produce honey, which can be harvested and used as a natural sweetener.
• Pollination: Bees are essential pollinators for many fruit and vegetable crops, improving yields and quality.
• Wax: Beeswax can be used for making candles, cosmetics, and various household products.

12. Fish (in aquaponics or small ponds):

• Meat: Fish such as tilapia, catfish, or trout can be raised for their meat.
• Aquaponics: Fish can be integrated into an aquaponics system, where their waste provides nutrients for plants, and the plants help filter the water for the fish.

13. Llamas and alpacas:

• Fibre: Both llamas and alpacas produce soft, warm fibre that can be used for making yarn, clothing, and other textiles.
• Pack animals: Llamas and alpacas can be used as pack animals for carrying loads.
• Guard animals: Llamas, in particular, can act as guard animals, protecting livestock from predators.

14. Turkeys:

• Meat: Turkeys are raised for their meat, particularly for holiday feasts.
• Pest control: Turkeys, like chickens and ducks, can help control pests by eating insects and larvae.
