Dr. Kevin Burgoon Purina Honor Show Chow Nutritionist Feed conversion ratios (the amount of feed eaten by a fish relative to the amount that fish provides for human consumption) vary among species, but farmed fish are far more efficient at converting feed than wild fish or other farmed animals such as cows and pigs. been emphasized for this reason. What are potential alternatives to feeding fish to fish? In lactating cows, when compared to other sources of undegradable protein such as soybean meal or cottonseed meal, fish meal gave higher results (Broderick, 2005; Broderick et al., 2000; Korhonen et al., 2002), improving amino acid balance and reducing N excretion (Ohgi, 2004; Abu-Ghazaleh et al., 2001; Schroeder et al., 2000). can give a total estimate of quality. herring as an industrial raw material actually started as early as about 800 AD sharing sensitive information, make sure youre on a federal about 50 per cent, and the oil content reduced to about 4 per cent.
