Grasscutter Rearing and Production

 Grasscutter Rearing and Production Origin and physical features  The grasscutter belongs to the order Rodent and family Thryonomidae which contains only genus Thryonomys. This rodent is widely known through Africa, South of Sahara and it is commonly referred to as the grasscutter, cane-rat or cutting grass.  They are heavily built, thick, set with rounded muzzle, small round ears, short tails and harsh bristly fur.  They have a peculiar bristle tail which readily fractures near the base if seized, much like the easily atomized tail of the lizard; a phenomenon that is of tremendous protective value.  The coarse bristly coat has no under-fur, though under magnification some sparsely scattered extremely fine straight under-fur is visible.  The overall appearance is usually dark brown, speckled with yellow or grey above butty white below.  The chin and throat appear white.  The head is a bit small for the size of the body.  The small circular ear is covered strong and well padded and are armed with powerful straight claws.  There are five digits feet.  Females have three pairs of mammary glands on the belly, while the male testes are not rodents.  The total body length (head to tail) ranged from 40 to 60cm and its tail length ranges from 7-25cm.  Grasscutter grows to a considerable weight.  The mature male sometimes reaches more that 9kg, while the female can attain between 5-7kg body weights.  Its growth rate is less than that of rabbit of an improved breed and more than that of the local rabbit in a tropical environment.  The animal has many predators including leopards, mongoose and python in addition to man. Reproduction and Breeding

A male and female grasscutter attains their sexual maturity at 5 and 7months respectively.  A male grasscutter can be paired with 3-5 females.  There are two methods of mating – permanent and controlled mating methods.  The gestation period is 152 day (5 months), meaning that with good management, the animal can litter twice in a year.  The average litter size is always 5.  The young ones can be weaned in about 4-6 weeks, after a resting period of about 10 days mother can be paired with the male again.  They are mature for food in 10-12 months, which raise their body weight to about 5-7kg.  They have the possibility of producing 2 times a year with good management and feeding, and they can constantly reproduce 4yrs before selling them out as old layer. Handling Grasscutter can be handled either by tails or by the limb.  For easy handling, wire mesh cages can be used to move animal from one place to the other. Feeds and Feeding Procedure

of grasscutter farming embarked upon by the farmer (breeding or fattening), provision of quality and adequate nutrition is essential to the success of each grasscutter rearing.  Balanced feeding that takes into consideration nutritional requirements and regularity of feeding are essential factors responsible for the animals’ good health, growth and reproduction.

Initial start-up investment


Build a wooden cage for N30,000

Purchase 1 family of four grasscutter (one male and 3 females) = N45,000

Get your food supplements (soya bean, crushed animal bone, PKC) for N20,000

Miscellaneous = N5,000


Total = N100,000



Expected Income/profit on investment


1 female can give birth to an average of 4 animals within 6 months


Therefore, 3 females x 4 = 12 animals in 6 months


If they reproduce another 12 animals in the other 6months; it shows that 1 family of grasscutter will reproduce an average of about 30 animals in a year.


1 grasscutter weigh between 4-5kg at maturity, that can be sold for an average price of N6,500


Hence, N6,500 x 30 = N195,000


Therefore: Net profit for rearing 1 family of grasscutter will be N195,000 – N100,000 = N95,000


Don’t forget that the first set of 12 grasscutter animal litter will also reproduce their kind in another 5-6 months.  Therefore, your animals will keep multiplying as the young ones will grow to reproduce more.
