A nutritional evaluation of diets containing meat meal for growing pigs. 5. Effect of rate of feeding on growth promoting ability of meat meal and meat and bone meal and the relationship between pig and rat responses

Abstract

Experiments were conducted to determine the effect of rate of feeding on the differences in growth promoting ability of wheat-based diets containing meat meal or meat and bone meal as the sole protein supplement for pigs. The value of laboratory rats in assessing diet quality for pigs was also investigated. There was no difference in the growth promoting abilities of diets containing MM or MBM under restricted feeding but under ad lib. feeding variation between the diets occurred. Rat responses to the dietary treatments were inconsistent with the pig responses. The results confirmed previous findings that under restricted feeding meat meals and meat and bone meals had similar growth promoting abilities for pigs.
