Rat meal

Related feed(s) 

In many countries there are established rat control programs, and rats that have been killed can be collected and processed to produce rat meal, which can then be used as a supplementary protein source for animals. Only very limited research has been conducted to assess the feeding characteristics of rat meal.

Nutritional aspects
Potential constraints 

As with any other animal derived product, care needs to be taken to ensure that adequate heat is applied during the processing to destroy any pathogenic organisms that might be present. If rats were poisoned, then caution needs to be taken to assure that the type of poison used will not be harmful to animals that the rat meal is fed to.


Two experiments in the Philippines have studied the inclusion of rat meal in broiler diets. Rat meal was prepared from freshly collected dead rats in newly ploughed rice and maize fields. The rats were boiled, sun-dried for 3-4 days and hammer-milled. In the first experiment, rat meal was included in broiler diets at 0, 4, 8, 12% and performance (growth) was increased (Aquino et al., 1987). In a second trial, broilers fed 10% rat meal had similar or higher growth than broilers fed 10% fish meal or 10% shrimp meal (Aquino, 1985).
