Le Duc Ngoan ; Ogle, B. ; Lindberg, J. E., 2001. Effects of replacing fish meal with ensiled shrimp by-product on the performance and carcass characteristics of growing pigs.. Asian-Aust. J. Anim. Sci., 14 (1): 82-87

36 crossbred (Large White * Mong Cai) pigs, with an average initial body weight (BW) of 19.4 kg, were randomly allocated to one of 3 different dietary treatments in which the crude protein of the fish meal (FM) was replaced with 0, 50 or 100% ensiled shrimp by-product (ESB) (Vietnam [date not given]). The animals were fed restrictedly and at the end of the experiment at a BW of about 90 kg, 6 representative animals in each treatment group were slaughtered for carcass quality evaluation. Animal growth performance and daily feed intake were significantly reduced (P<0.05) by the inclusion of shrimp by-products in the diets, whereas feed conversion ratios and carcass measurements were not significantly affected (>0.05). Daily weight gains of the pigs fed with 100% FM and 50% ESB diets were significantly (P<0.05) higher than those of pigs fed the 100% ESB diet. In conclusion, from an economical as well as performance point of view, ESB can replace 50% of the crude protein of FM in cassava root meal and rice bran-based diets for growing pigs with a low genetic growth potential.
