“…Lovell et al (1968) stated that crayfish meal contains approximately 18% calcium and should constitute no more than 10% of most animal rations. Kifer and Bauersfeld (1969), Lubitz et al (1943), andParkhurst et al (1944) also restricted crab meal to 10% of poultry rations, due to high calcium levels. Due to this 10% restriction, crustacean meals themselves supply little protein, therefore contributing greatly to the reluctance of feed manufacturers to include these meals in their rations.…”

“…silage may be the result of a combination of more indigestible fiber contributed by the straw and the high levels of chitin and ash in crab waste. Lovell et al (1968) and Lubitz et al (1943) reported that a high level of Ca in shellfish waste lowered the available energy in rats and chickens, respectively. In the present study, the value for DM digestibility was 50%, calculated by difference when 50% silage was fed, compared with 44% when 100% silage was fed.…”

Crab waste preserved with .2% NaOCl was mixed with wheat straw, liquid molasses, and water (32:32:16:20, wet basis) and ensiled for a minimum of 8 wk with microbial inoculant. A reduction in pH and water-soluble carbohydrates (WSC) and a higher concentration of lactic acid (4.9%, DM basis) were achieved. The trimethylamine (TMA) concentration in the silage was 11.2 mg N/100 g. In a digestion trial, 18 crossbred wethers (43 kg) were fed three diets: 1) basal, 2) a 50:50 mixture, DM basis, of basal and crab waste-straw silage, and 3) 100% crab waste-straw silage. Apparent digestibility of DM, OM, CP, energy, NDF, ADF, cellulose, and hemicellulose decreased linearly (P < .01) with increased levels of crab waste-straw silage. Nitrogen retention increased linearly (P < .05) with level of crab waste-straw silage. Apparent absorption was higher (P < .01) and retention was positive (P < .05) for Ca, Mg, Na, K, Cu, and Fe for sheep fed the highest level of crab waste-straw silage. In a 108-d trial, 30 yearling steers were fed diets in which crab waste-straw silage was included in the diet at 0, 15, and 26%, DM basis. Average daily gain tended to be highest (linear effect, P < .15) and carcass weights were highest (linear effect, P < .05) for steers fed 26% crab waste-straw silage. Average carcass quality grade was low Choice, and yield grade averaged 2.3, with no significant differences among treatments. Consumption of crab waste-straw silage did not adversely affect the taste of the meat. Results indicate that feeding crab waste-straw silage did not adversely affect nutrient utilization or performance of ruminants.

“…Starfish meal differs from crab meal in its fiber content. As the fiber is presumed to be chitinous in character and therefore of no supplementary protein value to chicks (Lubitz et al 1943), the low fiber content (0.4-0.55 percent) of starfish meal should be advantageous. The phosphorus and manganese contents of starfish meal are relatively low in comparison with crab meal.…”

“…Ewing (1943) reviewed the manufacture and use of fish meals in poultry rations. Lubitz, Fellers, and Parkhurst (1943) summarized the nutritive properties of crab meal; Parkhurst, Gutowska, Lubitz, and Fellers (1944) reviewed the research done with crab meal in starting rations. They reported that commercially produced crab meal could be used as a protein concentrate in starter and broiler rations, and could satisfactorily replace fish meal when the content and ratio of calcium and phosphorus in the ration was adjusted.…”
