“…However, the levels of 37.5% and 45.0% did give significantly poorer gains with the big difference occurring between the 30 and 37.5% level. These results are in agreement with Enriquez and Ross (1967) who obtained no significant differences with levels of cassava up to 30% compared with the basal containing no cassava. They observed significantly poorer gains when 40 and 50% of the ration consisted of cassava meal.…”

“…Poorer growth and feed conversion with chicks at three weeks of age with increasing cassava root meal concentrations in the diet were reported by Enriquez and Ross (1967). Supplementing the high cassava rations with 0.15% methionine largely overcome the depressing effects.…”

“…Recommended levels of cassava (Manihot esculenta Crantz) root meal (CRM) for inclusion in broiler diets range from 10 (Vogt, 1966) and 30% (Montilla et al, 1969(Montilla et al, , 1975Armas and Chicco, 1973;Enriquez et al, 1977) to 50% (Enriquez and Ross, 1967;Olson et al, 1969;Tejada and Brambilla, 1969;Chou and Miiller, 1972). The variability and lack of consistency of the reported results may have been partially due to differences in experimental conditions and in cassava root processing methods used.…”

Effects of the Addition of Vegetable Oil or Animal Tallow to Broiler Diets Containing Cassava Root Meal

Two experiments were carried out to evaluate the effects on broiler performance of increasing by 5% the metabolizable energy level of diets containing cassava (Manihot esculenta Crantz) root meal (CRM: 0, 20, and 30%) by adding either vegetable oil (Experiment 1) or animal tallow (Experiment 2). The CRM used was detoxified by sun-drying whole root chips of a high cyanide-containing (bitter) cultivar (CMC-84) on a concrete floor. All experimental diets were supplied in mash form. Supplementary vegetable oil or animal tallow did not affect (P greater than .05) growth rate. Feed conversion (feed/gain) was improved (P less than .05) during the starter (0 to 28 days) period as well as at the end of the experiments (56 days). Body weight gain, feed consumption, and feed conversion were not affected (P greater than .05) by any of the dietary treatments during the finishing (28 to 56 days) period of both experiments. Diets containing 20% CRM produced somewhat higher (P greater than .05; Experiment 1) or significantly higher (P less than .05, Experiment 2) final body weights.

“…The responses to methionine supplementation observed with snail meal diets in Experiments 3 and 4 cannot be explained on the basis of correcting a simple methionine deficiency, since calculated levels in these diets met the birds requirements. It would seem to be more likely an example of methionine's well known effect (Enriquez and Ross, 1967) in allowing detoxification of some unknown antigrowth factor in snail meal.…”

Snail meal made from the bodies of the African giant snail (Achatina fulica) was investigated for chemical composition and nutritional value for broiler chickens. The meal contained approximately 60% protein, 2% calcium, .8% phosphorus, 4.35% lysine, 1% methionine, and .6% cystine on a dry matter basis. Metabolizable energy (ME) was 14.2 MJ/kg (3400 kcal/kg) dry matter. An inhibitor was present in the raw snails that depressed growth when the meal was included in diets at levels above 10%. Boiling the snails for 15 to 20 min prior to processing completely overcame this depression. Graded levels of boiled snail meal up to 15% of the diet gave similar weight gains to those of a control diet fed to broiler chickens to 28 days of age. The growth depression that resulted from feeding 20% boiled snail meal was overcome by the addition of .25% DL-methionine. A further experiment indicated that .2 or .3% DL-methionine was required to achieve maximum performance of chickens fed 20% snail meal. A control diet, however, was not improved by adding DL-methionine beyond.1%. A significant improvement in growth was obtained from adding 5 or 10% of either fish meal or snail meal to a corn-soybean meal diet. This suggested the presence of unidentified growth factors in snail meal similar to those claimed for fish meal. (
