THE POSSIBILITY FOR FISH-MEAL SUBSTITUTION IN PIGLET FEEDING

The possibility substitution of fish meal with a high protein meal for feeding weaned piglets was investigated. The high protein meal was pr oduced by combining blood, meat and hidrolized feather meal. The fish meal was substitute TR?5Tn basis. The high protein meal was added to t he starter mash for piglets (treatment A) substituting for two-thirds (treatment B) or the complete amount (4%) of fish meal (treatment C). This reduced the average daily weight gain by 6.83% (treatment B) and 7.38% (treatment C) respectively compared to the control diet (treatme nt A). Feed conversion per unit of weight gain was 6.33% higher (treat ment B) and 8.02% higher (treatment C) than in piglets fed the control mash (treatment A). The carcass quality of the piglets fed the ration s containing high protein meal instead of two-thirds of the fish meal was comparable to the carcass quality of the piglets on control treatm ent A.
