Nutritional value, performance, carcass quality, visceral organ size, and blood clinical chemistry of broiler chicks fed 30percent tannin-free fava bean diets

Two experiments were conducted to evaluate the chemical and nutritional values of 5 tannin-free fava bean (FB) cultivars (FB9, FB10, FB13, FB17, and FB24) on growth, visceral organ size, and blood clinical chemistry of broiler chicks fed a corn-soybean meal 48 (SBM48) diet containing 30percent tannin-free FB. In the first experiment, 49 Hy-line roosters, 55 wk of age, were individually precision-fed 30 g of each FB cultivar and soybean meal 44 (SBM44). Protein, methionine, and lysine contents of the FB seeds (0.005percent tannin) were 27.7, 0.23, and 1.98percent of DM, respectively. The AMEn of all FB cultivars was 2,839 kcal-kg and higher (P andlt; 0.05) than SBM44. The true lysine digestibility of FB10 (94.1) was higher (P andlt; 0.05) than FB9 (89.0percent) and FB24 (89.2percent), but comparable with the other fava beans. The FB cultivar's true methionine digestibilities were similar among each other and to SBM44. In a battery feeding trial, 6 corn-SBM48 diets containing 0 (control) or 30percent of FB9, FB10, FB13, FB17, or FB24 seeds were each fed to Ross 308 1-wk-old male broiler chicks for 14 d. The determined FB nutrient values were used in formulating FB-containing diets. Birds fed FB-containing diets had better (P andlt; 0.05) weight gain and feed conversion than those of the control. When compared with the control birds, relative weights of abdominal fat pad and liver were reduced (P andlt; 0.05) by 30percent inclusion of all dietary FB varieties, except for FB17 and FB13, respectively. Broiler chicks fed the FB13 diet had plasma thrombocyte and white blood cell (WBC) differential counts higher (P andlt; 0.05) than those fed the FB10 diet and WBC count higher (P andlt; 0.05) than the birds fed the FB17 diet. In conclusion, tannin-free FB was lower in protein, methionine, and lysine, but higher in AMEn, compared with SBM44. Moreover, FB seeds, especially FB10, can be included in a broiler chick diet with no adverse effects on performance, but FB13 increased WBC count. © 2014 Poultry Science Association Inc.
