Abstract
It was reported that heated whole fish meal produced from mackerel and sardine induced gizzard erosion in poultry by feeding with high levels in diet, however, the influence of the heated whole fish meal on animals except poultry has not been reported. In this experiment, the influences on rat were investigated. One-month-old rats were devided into two groups of 10 rats each and they were reared in cages individualy for 8 months. The rats of test group were fed a test diet containing 20% heated fish meal that induced gizzard erosion and growth depres sion in broiler chicks. The control rats were fed a commercial rat diet. Body weight was recorded every month and the rats were sacrificed at nine months of age for visual observation of internal organs. At the same time, weights of several organs (stomach, liver, kidney, spleen, lungs, heart) and chemical values (hemoglobin, serum total protein, blood urea nitrogen, glucose, glutamic oxalacetic transaminase, glutamic pyruvic transaminase) of clinical blood test were meas ured. In these visual observations and measuring values, no significant difference was observed between the two groups. From these results, it was considered that the heated whole fish meal that induce gizzard erosion in poultry had little influence on rat.
