The conditions for the polyenzyme method were pH of 7.0, temperature of 50℃, alkaline and neutral protease concentration of 1.5% respectively, hydrolysis time of 120 min, and flavorase concentration of 2.0%, for 60 min. The new gravy making technology yields a nutritious and delicious gravy containing 40.3% of total essential amino acids, with delicious amino acids Glu, Asp, Gly, Ala, Pro and Ser comprising 49.5%, total and amino nitrogen being respectively 1.9 and 1.1 g/100 g (amino acid nitrogen being 61.0% of total nitrogen), The polyenzyme method was used to make 14.8% protein gravy from Harengula zunasi offal. In addition, in inorganic elements, the phosphorus content is the highest.展开更多

Fresh blood prevented from coagu- lation, mixed with maize offal, was sun-dried, ground, mixed again with blood and ground into a meal after drying again. The crude protein, fat, fibre, ash, ADF and gross energy contents of SDMBM were, 362.0, 45.5, 31.8, 69.3, 52.3 g/kg DM and 4.245 kcal/g, respectively. It was ade- quate in all essential amino acids for growing broiler chickens except methionine. Eighty 14- day-old commercial broiler chicks were ran- domly allocated to four dietary treatments (fed ad libitum;four replicates each) consisting the control diet (0 g SDMBM/kg diet), which con- tained fishmeal, groundnut cake and soybean meal, and three other diets (50, 100 and 150 g SDMBM/kg diet). In a feeding trial, the starter (14 to 35 d) and finisher (35 to 49 d) dietary treat- ments did not have significant impact (P > 0.05) on body weight gain, efficiency of feed conver- sion, mortality and final body weights. The con- trol diet was inferior (P < 0.05) to 50, 100 and 150 g SDMBM/kg diets for feed cost per unit weight gain in the starter phase, 100 g SDMBM/kg diet in the finisher phase, and 100 and 150 g SDMBM/ kg diets for the whole period (14 to 49 d). Overall, the 100 and 150 g superior (P < 0.05) to the con- trol diet in cost of production per unit weight gain and all the SDMBM diets greater than con- trol in economic benefit per unit weight gain. Results suggest that dietary SDMBM up to 150 g/kg diet has a positive effect on broiler per- formance and can totally replace more expen- sive fishmeal.展开更多
