Performance of growing pigs given diets in which fish meal was replaced by Tra catfish by products

Abstract

The effects of diets with four different protein sources were determined with respect to average daily gain, feed conversion ratio, back fat thickness and economic benefits in growing pigs. The four treatments were based on cassava root meal as energy source: A control treatment (FM) was cassava root meal plus marine fish meal; Treatment BM was cassava root meal plus catfish broken meat by-product meal; Diet OE was cassava root meal plus oil extracted catfish by-product meal and Diet BH was cassava root meal plus bone and head catfish by-product meal. The four diets were fed to twenty four growing pigs in a Randomized Complete Block Design with four treatments and six replications, and the experimental unit was one pig. There were differences among the diets in the average daily gain (ADG), dry matter intake (DMI), feed conversion ratio (FCR) and back fat thickness, with a descending trend from BM, OE, FM and BH (p < 0.05). The DMI, ADG, back fat thickness and iodine number were highest in BM (1955g, 629g, 13.7mm and 52.8, respectively) and lowest in BH (925g, 182g,7.81mm and 40.1, respectively). FCR in BM was the lowest (3.13 kg/kg gain) and highest in BH (5.31 kg/kg gain). It can be concluded that growth performance on the treatment with catfish broken meat by-product meal (BM) was best, followed by OE, FM and BH.
